    [0020] [0020] Skilled artisans will appreciate that elements in the figures are illustrated for simplicity and clarity and have not necessarily been drawn to scale. For example, the dimensions of some of the elements in the figures may be exaggerated relative to other elements to help to improve understanding of embodiments of the present invention.
    [0021] [0021] The apparatus and method components have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the present invention so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein.DETAILED DESCRIPTION
    [0022] [0022] Label printers are often desired for small business use, however for occasional users, the process of Joading media may end up being troublesome. Often times, label printers require media to be fed through a system of rollers within the Jabel printer, which adds additional complications to a media loading and unloading process. The description below seeks to remedy these complications through the use of a replaceable media cartridge.
    [0023] [0023] The below described media cartridge includes a media outlet having guide walls. The guide walls aids in alignment of media from the media cartridge which simplifies the design for the label printer/media cartridge combination as the guide walls allows for the media to be dispensed for printing in a relatively straight alignment.
    [0024] [0024] The below described media cartridge includes two sections, a media chamber and a cover having a first wing and a second wing. The first and second wings have a first and a second spindle. The first and second spindle are aligned such that when the media cartridge is assembled, they are opposite each other such that the first and second spindle can retain a roll of media. The first and second spindle being integral parts of the first and the second wing allows for the media cartridge to support the media within the media cartridge without having to include additional parts. This allows for a simplification of the design which allows the media cartridge to be assembled easier for less expensive production.
    [0025] [0025] An issue that may arise when a first time user attempts to load media into a printer is the media can be put in the wrong orientation, which could damage the media cartridge or the printer itself. The below described media cartridge addresses this issue via alignment features on the rear and lower surface of the media cartridge. The alignment features can be molded directly into the media cartridge itself and make it such that the media cartridge can obviously only fit in one set orientation. The alignment features may also makes it such that the media cartridge cannot easy shift within the printer during operation.
    [0026] [0026] Examples disclosed herein are directed to media cartridge, comprising: a base including: a media chamber having a mouth, and a lower portion of a media outlet; first and second wings configured to support a media spool therebetween; and a cover connected between the first and second wings, and including: an upper portion of the media outlet, and a perimeter configured to engage the mouth of the media chamber, to suspend the first and second wings within the media chamber and place the upper portion of the media outlet adjacent to the lower portion of the media outlet.
    [0027] [0027] Additional examples disclosed herein are directed to a media cartridge, comprising: a lower wall having a T-shaped alignment ridge extending therefrom, the alignment ridge configured to cooperate with a complementary lower channel in a printer housing to orient the media cartridge within the printer housing; a rear wall including an alignment spine extending therefrom to cooperate with a complementary rear channel of the printer housing; a set of further walls defining, in cooperation with the lower wall and the rear wall, a media chamber to support a media spool; a media outlet opposite the rear wall, configured to dispense media from the media spool.
    [0028] [0028] FIG. 1 depicts a media cartridge 100, also referred to herein simply as the cartridge 100. The cartridge 100 is configured to store a supply of media, such as a spool of adhesive labels, paper or the like, although the cartridge 100 is illustrated in an empty state in FIG. 1.
    [0029] [0029] The cartridge 100 includes a base 104 that defines a media chamber to contain the above-mentioned media spool. The cartridge 100 also includes a cover 108 that is configured, when the cartridge 100 is assembled as shown in FIG. 1, to engage with the base 104 to enclose the above-mentioned media chamber. The cover 108 is also coupled to internal components of the cartridge 100 that support the media spool, as will be seen below.
    [0030] [0030] The cartridge 100 includes a media outlet 112 from which media is dispensed from the media chamber, e.g. in the direction 16 indicated in FIG. 1.
    [0031] [0031] The base 104 and cover 108 cooperate to define the media outlet 12 when the cartridge is fully assembled, as shown in FIG. 1. To that end, the base 104 includes a lower portion 120 of the media outlet 112, over which the media travels in the direction 16 to exit the cartridge 100. The lower portion 120 of the media outlet 112 can be integrally formed with a forward wall 122 of the base 104.
    [0032] [0032] In addition, the lower portion 120 can include guide walls 124-1 and 124-2, which may be integrally formed with side walls 126 (a side wall 126-1 is shown in FIG. 1) of the base 104, for structural support of the lower portion 120. The guide walls 124 may also constrain sideways motion of the media (e.g. in the same plane as, but orthogonal to, the direction 116) as the media exist the cartridge 100. The guide walls 124 can include ridges (visible on the outer surface of the guide wall 124- 1) to retain structural rigidity while reducing wall thickness.
    [0033] [0033] The lower portion 120 of the media outlet 12 can also include a cutout 128 at a leading edge thereof. The cutout 128, as will be discussed below in greater detail, may allow media traversing the cutout 128 to be exposed to a sensor of the printer when the cartridge is installed in the printer.
    [0034] [0034] The cover 108 includes an upper portion 132 of the media outlet 112 configured to contact an upper surface of the media as the media exits the cartridge, e.g. to mitigate against retraction of the media into the cartridge 100.
    [0035] [0035] The side walls 126 of the cartridge 100, e.g. the side wall 126-1 as shown in FIG. 1, can include respective windows 136 (a window 136-1 is visible in FIG. 1) that expose the interior of the media chamber to the exterior of the cartridge 100. The windows 136 therefore enable an operator to view the media within the cartridge 100, e.g. to assess a remaining quantity of media.
    [0036] [0036] Turning to FIG. 2, the cartridge 100 also includes structural features to align the cartridge 100 within the printer upon installation. In the illustrated example, the cartridge 100 includes an alignment ridge 200 extending from a lower wall 204 of the base 104. The alignment ridge 200 is configured to engage with a complementary alignment channel of a printer, constraining the alignment of the cartridge 100 as the cartridge 100 is installed in the printer (i.e. preventing installation of the cartridge 100 in an incorrect orientation). In other examples, the alignment ridge 200 can be provided as a channel feature extending into the lower wall 204 rather than extending out from the lower wall 204. In such examples, the complementary structure in the printer can include a ridge configured to engage with the above-mentioned channel.
    [0037] [0037] In the present example, the alignment ridge 200 is a T-shaped ridge that includes a stem 208 and an arm 212. As shown in FIG. 2, a forward surface 216 of the arm 212 is contiguous with the forward wall 122 of the base 104. In other examples, however, the arm 212 can be disposed on the lower wall 204 such that the forward surface 216 is spaced apart (rearwardly) from the forward wall 122. In addition, the arm 212 extends across the width (between the side walls 126) of the base 104 in the present example. In other examples, the arm 212 can have a reduced length, such that the arm 212 extends across only a portion of the width of the base
    [0038] [0038] The stem 208 of the alignment ridge 200 is disposed centrally on the lower wall 204 and orthogonal to the arm 212. The stem 208 extends between the arm 212 and a rear end of the lower wall 204. In other examples, the length of the stem 208 can be reduced. In further examples, the stem 208 can be disposed off- center relative to the arm 212, such that the stem 208 is closer to, for example, the side wall 126-1 than to the opposing side wall 126 (not visible in FIG. 2).
    [0039] [0039] The cartridge 100 also includes an additional alignment feature in the present example, in the form of an alignment spine 220 extending from a rear wall
    [0040] [0040] In other examples, the alignment ridge 200 can have a variety of shapes other than the T-shaped configuration shown in the drawings. For example, the ridge 200 can be angled to traverse the lower wall 204 in a diagonal direction. In other examples, the ridge 200 can be implemented as a plurality of distinct ridges or bosses, as a curved ridge, and the like.
    [0042] [0042] Turning to FIG. 3, certain internal feature of the base 104 are illustrated as the cover 108 is omitted. In particular, in addition to the side wall 126-2 and the window 136-2, FIG. 3 shows the internal structure of the alignment ridge 200 and the spine 220. In particular, the ridge 200 is formed from a plurality of cells 300 in the lower wall 204. The depth of the cells 300 varies based on the position of the cells, as the lower surface of the ridge 200 is planar (as shown in FIG. 2), while the lower wall 204 is curved. The use of cells 300 to form the ridge 200 enables the ridge 200 to retain structural rigidity while reducing material use compared to a cartridge 100 in which the ridge 200 is a solid component extending from the lower wall 204. The cells 300 can, therefore, enable manufacturing of the cartridge via injection molding, e.g. with a recyclable and/or biodegradable material. Examples of such materials include a paper foam containing paper pulp and starch. The spine 220 is also formed from a pair of cells 304 in the present example.
    [0043] [0043] FIG. 3 also illustrates a media chamber 308, as mentioned previously.
    [0044] [0044] Turning to FIG. 4, certain features of an example printer 400 with which the cartridge 100 may be used will be discussed. The printer 400, e.g. a desktop label printer, includes a housing 404 to receive the cartridge 100, and a lid 408 to enclose the cartridge 100 within the housing 404 when the lid 408 is closed (the lid 408 is shown in an open position in FIG. 4). The housing 404 supports a print head assembly 412, and the lid 408 supports a platen roller 416 that, when the lid 408 is closed, cooperates with the print head 412 to form a nip through which media is drawn from the cartridge 100 for processing and dispensing from the printer 400.
    [0045] [0045] Within the housing 404, the printer 400 includes an alignment channel] 420 that, in the illustrated example, has a T shape complementary to the shape of the alignment ridge 200 discussed above. The housing 400 also defines a rear alignment channel 424 that is complementary with the shape of the spine 220 discussed above. Thus, as the cartridge 100 is inserted into the printer 400, the spine 220 engages with the channel 424 to guide the ridge 200 into the channel
    [0046] [0046] The printer 400 also includes, within the channel 420, an electrical interface 428 configured to engage with the circuit 228 when the cartridge 100 is inserted into the housing 404. Further, the lid 408 can be configured to apply pressure to the cover 108 above the circuit 228 and the interface 428, to encourage tull contact between the circuit 228 and the interface 428. In particular, the lid 408 includes a pressure bar 436 on an inner surface thereof. The pressure bar 436 is configured, when the lid 408 rotates from the illustrated open position to a closed position, to exert downwards pressure on the identification circuit 228 via the ledge 316 and spine 220. Such downwards pressure may serve to ensure contact between the circuit 228 and the interface 428.
    [0047] [0047] Also shown in FIG. 4 is a sensor aperture 432. The sensor aperture 432 can contain a sensor (e.g. an optical sensor) to detect the presence of media. As will now be apparent, when the cartridge 100 is installed within the housing 404, the cutout 128 is disposed over the sensor aperture 432, such that the lower portion 120 of the media outlet 112 does not obstruct the above-mentioned sensor. The cutout 128, in the illustrated example, is open to form a bay in the leading edge of the lower portion 120. In other examples, the cutout can be closed, to form an opening through the lower portion 120 while the leading edge remains straight.
    [0048] [0048] Turning to FIG. 5, a simplified overhead view of the printer housing 404 is shown, illustrating the channels 420 and 424. Also shown are three example cartridges 100a, 100b and 100c of different sizes. For example, the cartridge 1004 may contain Jabels with a width of two inches, while the cartridge 100b may contain Jabels with a width of three inches and the cartridge 100b may contain labels with a width of four inches (a wide variety of other Jabel dimensions are also contemplated). Respective alignment ridges and spines 2004, 200b, 200c and 2204, 220b and 220c of each cartridge 100 are illustrated. As shown in FIG. 5, each cartridge 100 can be accommodated within the printer housing 404 and guided into position via engagement of the ridges 200 and spines 220 with the channels 420 and 424. Thus, a printer 400 sized to receive labels of widths up to four inches may also be compatible with cartridges containing narrower media.
    [0049] [0049] Referring now to FIG. 6, the loading and assembly of the cartridge 100 will be discussed in greater detail. FIG. 6 illustrates the cartridge 100 in a disassembled state, prior to loading of the cartridge 100 with media. As seen in FIG. 6, in addition to the base 104 and cover 108, the cartridge 100 includes first and second wings 600-1 and 600-2. The wings 600 are connected on opposing sides of the cover 108, e.g. via living hinges 604-1 and 604-2 that permit rotation of the wings 600 relative to the cover 108.
    [0050] [0050] Referring now to FIG. 6, the cover 108 and wings 600 can be manufactured as a single integrated component (e.g. via injection molding as mentioned earlier), while the base 104 can be manufactured as a separate component. In some examples, however, the entire cartridge 100 can be manufactured as a single integrated component, e.g. via injection molding. In such examples, the cover 108 is connected to the base 104 via a hinge in the region 606 indicated in FIG. 6. The hinge between the cover 108 and base 104 can be implemented as a living hinge of the same material as the cover 108, wings 600 and base 104. In some examples, e.g. if a greater range of motion between the cover 108 and the base 104 is to be provided than a living hinge can accommodate, a separate hinge member can join the cover 104 and 108. For example, a paper hinge can be placed in a mold and the cover 108 and base 104 can be overmolded onto the paper hinge.
    [0051] [0051] The wings 600 are configured to engage and support a spool of media. To that end, each wing 600 is a generally planar member supporting structural features on an inner surface (the surface visible in FIG. 6) thereof. The above- mentioned features include a spindle 608-1, 608-2 that is configured to engage with a core (e.g. a cylindrical cardboard core) of a media spool. When the wings 600 are rotated relative to the cover 108 to support the media spool, the spindles 608 align to form an axis of rotation about which the media spool rotates to dispense media.
    [0052] [0052] The wings 600 can also each include at least one guide fin 612-1, 612-2. In the illustrated example, each wing 600 includes a set of guide fins 612 surrounding the spindle 608. Each guide fin 612 includes a leading end 616-1, 616-2 and a trailing end 620-1, 620-2. The ends 616 and 620 are referred to as leading and trailing in relation to the direction in which the media spool rotates related to the wings 600 when installed. As will be apparent in the discussion below, the direction of rotation of the media spool relative to the wing 600-1 is counter- clockwise (as indicated by the arrow Ri). The direction of rotation of the media spool relative to the wing 600-2 is counter-clockwise (as indicated by the arrow R2). The leading ends 616, in other words, are the furthest extents of the fins 612 in the direction of rotation, while the trailing ends are the furthest extents of the fins 612 opposite the direction of rotation.
    [0053] [0053] The guide fins 612 are angled inwards, towards the spindle 608. In other words, the leading ends 616 are closer to the spindle 608 than the trailing ends 620. Further, the fins 612 are configured to contact the media spool when the cartridge 100 is loaded and assembled. The angling of the fins 612 configures the tins 612 to guide the media on the spool towards the spindle 608, mitigating unwinding of the spool. When not mitigated, such unwinding can cause slack to accumulate in the media and negatively affect print quality. The fins 612 are curved in the present example, such that an inner edge of each fin 612 (closer to the spindle 608) is concave while the opposing outer edge is convex. In other examples, the fins 612 need not be curved.
    [0054] [0054] Each wing 600 also includes a window 624-1, 624-2 therethrough. As will be shown below, the windows 624 are configured to align with the windows 136 in the side walls 126 of the base 104 when the cartridge 100 is assembled, such that the interior of the media chamber 308 is visible from the exterior of the cartridge
    [0055] [0055] In addition, each wing 600 can include a latch 632-1, 632-2, each configured to engage a corresponding opening 636 of the base 104 (an opening 636- 1 is visible in FIG. 6). The latches 632, as shown in FIG. 6, extend from the distal edges (i.e. the edges furthest from the hinges 604) of the respective wings 600. In addition, each latch 632 extends from the corresponding wing 600 at or near a forward side of the wing 600, such that when the wing 600 is received in the base 104, the latch 632 is placed closer to the outlet 112 than to the rear wall 224. Together, the blocks 628 and the latches 632 secure the wings 600 to the base 104 when the cartridge 100 is assembled.
    [0056] [0056] Certain additional features of the cover 108 are also visible in FIG. 6. In particular, the cover 108 includes a perimeter 640 that is configured to engage the mouth 312 of the base 104, to enclose the media chamber 308. The cover 108 can also include a set of internal ridges 644 for structural rigidity.
    [0057] [0057] Turning now to FIG. 7, a process for loading the cartridge 100 will be discussed. To load the cartridge 100, a media spool 700 is placed adjacent to the cover 108 (specifically, the interior of the cover 108, near the ridges 644). The media spool 700 includes a length of labels or other media joined by a removable backing or the like and wound about a core 704, such as a cardboard cylinder. The wings 600 are then rotated relative to the cover 108, as shown by the curved arrows in FIG. 7, to close onto the media spool 700 such that the spindles 608 are received within opposing ends of the core 704. The spindles 608 thus support the media spool 700 and define an axis of rotation for the media spool 700.
    [0058] [0058] Turning to FIG. 8, when the wings 600 come into contact with the sides of the media spool 700, the wings 600 are inserted into the media chamber 308 of the base 104. For example, when the cover 108 is attached to the base 104 (e.g. by a hinge in the region 606 as mentioned earlier), the cover 108 is rotated relative to the base 104 in the direction shown by the curved arrow in FIG. 8.
    [0059] [0059] As the wings 600 and the media spool 700 travel into the base 104, as shown in FIG. 9, the blocks 628 engage with the windows 136, and the latches 632 engage with the openings 636. The blocks 628 and the windows 136 have complementary wedge shapes, with upper ends of the blocks 628 and windows 136 (that is, ends closer to the cover 108 than to the lower wall 204 of the base 104) being narrower than lower ends of the blocks 628 and windows 136. The wedge shape of the blocks 628 and windows 136 mitigates against upwards motion of the cover 108 relative to the base 104, which would retract the wings 600 out of the media chamber 308. In addition, as seen in FIG. 9, a height of each block 628 is smaller than a height of the corresponding window 136, such that a portion of the window 136 remains unobstructed by the block 628 to permit visibility of the media chamber 308 through the unobstructed portion.
    [0060] [0060] The blocks 628 and the latches 632 thus prevent the wings 600 and cover 108 from returning towards the open positions shown in FIGS. 6-8, and may also mitigate movement of the wings 600 (and therefore of the media spool 700) within the media chamber 308. As also shown in FIG. 9, media goo from the spool 700 extends from the outlet 112, to be engaged by the nip of the printer 400 when the cartridge 100 is installed within the printer 400. The upper portion 132 of the outlet 112 defines a retaining wall that contacts the media 900 and mitigates retraction of the media 900 into the chamber 308, for example during transport and handling of the cartridge 100 prior to installation.
    [0061] [0061] Turning to FIG. 10, a cross-sectional view of the cartridge 100 and media spool 700 is shown. To dispense the media goo from the spool 700, the spool 700 rotates clockwise (in the orientation shown in FIG. 10). As also shown in FIG. 10, the ridges 644 within the cover 108 have curved cutout portions 1000 shaped to accommodate the spool 700. The cutouts 1000 are spaced apart from the spool 700 such that in operation, the ridges 644 do not contact the spool 700. However, during transport and handling, the spool 700 may contact the ridges 644, which act to limit the range of movement of the spool 700 within the chamber 308.
    [0062] [0062] FIG. 1 illustrates a detail view of the outlet 12 and certain components of the printer 400. As seen in FIG. 11, the Jower portion 120 of the outlet 112 includes a surface 1100 that defines an exit angle for the media 900. The printer 400 defines a media path 1104, e.g. with one or more guide structures 1108, towards the nip formed by the print head 412 and the platen roller 416. As seen in FIG. u, the exit angle defined by the surface 1100 matches the angle of the media path 1104.
    [0063] [0063] FIGS. 12A, 12B, 13A, 13B, 14A, 14B, 15 and 16 depict various views of an example media cartridge, e.g. configured to accept a first width of media such as one-inch wide labels. FIGS. 17A and 17B depict a media cartridge configured to accept a second width of media (e.g. two-inch wide labels). FIGS. 18A and 18B depict a media cartridge configured to accept a third width of media (e.g. four-inch wide labels).
    [0064] [0064] In the foregoing specification, specific embodiments have been described. However, one of ordinary skill in the art appreciates that various modifications and changes can be made without departing from the scope of the invention as set forth in the claims below.
