    The device for transporting an ink-ribbon (6) and a correction-ribbon (7) for a type element typewriter has a cartridge holder (3) which is pivoted together with the ink-ribbon and correction-ribbon cartridge (4, 5) when the latter is inclined in order to present a part of the ink-ribbon (6) or of the correction-ribbon (7) at the printing point. The transporting and lifting of the ink-ribbon for printing are carried out by means of a cam (22) on which there are arranged several groups of elevations. The correction-ribbon (7) is driven by means of a second cam (35) which is actuated only when the machine is working in correction operation. The correction operation is controlled by pressing down the rear side of the cartridges (4, 5), their front part being raised and the correction-ribbon (7) being moved into its working position. <IMAGE>

    The invention relates to a tape drive mechanism of a printing device and can be used in a typewriter. A device for moving ink and correction tape of a typewriter containing mounted on the base in the box office with feed and receiving coils with tapes and means for moving them is known. including mounted ratchet wheels with corresponding coil coils kinematically connected to a main shaft 1 J. A disadvantage of the known devices is the relative complexity awn yc Novki means for moving katu nis ribbons into a cassette that is negative effect on reliability ma va. The aim of the invention is to increase the reliability of the device. The goal is achieved by the fact that in a device for moving the cutting and correcting tapes of a typewriter, containing cassettes with feed and receiving arcs of tape reels and means for moving them, including ratchet wheels mounted in cooperation with the corresponding coils , kinematheski associated with the main shaft, the means for moving the belts are mounted in the housing cams and tappets, mounted on the base with the possibility of interaction with the cu kinematically connected with the ratchet wheels, while the base of the cassettes is hinged in the housing and connected to the cam of the means for moving the colored tape by means of a lever. In addition, the cam of the means for displacing the dye ribbon has protrusions arranged in pairs on its opposite sides, with the height of each protrusion of one pair being twice the height of the adjacent protrusion of the other pair. Fig. 1 shows a writing machine, a general view, in Fig. 2, the same, top view, in Fig. 3-7, elements of the proposed device, in Fig. 8, proposed. device in isometric projection, bottom view; in FIG. 9, the same, second variant; in FIG. 10, cams, top view. . The frame 1 of the typewriter has an internal support pin 2 mounted on the base end of the cassette holder cassette 3 carrying the cassette 4 and 5. The cassette holder 3 can accommodate holes through which the loops of the dye tape b and the corresponding correction tape 7 can go out of the cassettes and enter them and both the loop loops formed in this way are arranged one above the other. They pass in the space between the printing device 8 and the roller 9 for paper. On the cassette holder 3 are placed the remaining parts of the device for drawing the dye tape. . A pin 11 is mounted on the panel 10, which is part of or fixed to the cassette holder 3. On the pin there are two rocker arm 12 and 13 that can rotate independently of each other. The rocker arm at its end carries a ratchet mechanism for driving the paint in one direction. tapes in cassette 4 (5). The ratchet mechanism is a ratchet needle wheel 14, in the opening 15 of which the hook 16 enters, forming the curved end of the lever 17. The end of the lever 17 is mounted coaxially on the same axis 18 as the needle wheel 14. Rviag 17 through movement fixed at its end 19 is driven from the cam follower 20, installed with the possibility of being pushed onto the rotating trunnion 21. The follower 20, as well as The cam 22, on the surface of which it moves, is located on the frame of a typewriter. The cam 22 is rotatably mounted on the frame 1 and driven through the gear pair 23, which consists of an IM attached on the cam shaft 24 of the gear 25 and the gear 26, which is mounted on the main shaft 27 of the typewriter. . The device for driving the wheels and the ratchet device for the rocker arms 13 (Figures 2 and 3 has the same structure and principle of operation as the devices described for the bark of the number 12 and serves to draw a correction tape placed in the corresponding chamber of the cassette. 28 is driven through a hook-hook 30. 30. The yoke 29 is rotatably mounted on the axis 31 of Fig. 8. For transfer to the rocker arm 29, it is connected at its end with a pull 32 dr The end of the cam follower 33. The follower 33 (FIG. 9) has a CB-6ofiy displacement in the direction of the main shaft 27, so that it can be moved together with the base of the cassette cassette 3, if the latter moves in order and, accordingly, the correction tape is brought into position for printing.
    Since the cam follower 33 is mounted on the cassette holder 3, it can be rotated on its rotating axis so that the protrusion 34 of the pusher 33 when tilting the cassette holder 3 can be shifted to the pick-up area of the cam 35 belonging to the correction tape. The cam 35 of FIG. 9 is mounted coaxially on the main shaft 27 by a typewriter and with which it rotates. The cam 35 (FIGS. 5-7) and 10 are aligned with the cam 22 belonging to the dye tape so that the pusher 33 can engage with the cam profile only if the rear side of the cassettes 4 and 5 is sufficient, and the cassette holder 3 is rotated around its axis and the correction tape 7 is set in the printing position.
    When pushing the pusher 33 onto the cam 35, the pusher 33 rotates and transmits an oscillating movement to the rocker 29 in such a way that with each turn of the main shaft. 27, the ratchet (needle) wheel 28 for the correction tape is rotated until the cassette holder 3 is in the position at which the correction tape is placed in the printing position. While the pusher 33 rests on the cam 35, which is otherwise normal, the non-printing operation causes the type printing element to strike the correction tape pressed against the paper in the printing position. When the main shaft rotates, the protrusion 34 on the pusher 33 sliding along the surface of the cam 35 oscillates and causes stretching of the correction tape 7. in the cassette 5 for the correction tape.
    The lever 36 (Fig. 9) is mounted on a pivot axle 37 in frame 1. At the end of lever 36, a pin 38 is fixed. To retract the needle wheel 14 located on the rocker arm 12 together with the needle wheel 28 on the rocker arm 13, from the paint cartridge and The ptwar 36 can be rotated by turning the clock hand around its axis so o6pia3OM that the pin 39 of the rocker arm 12 is in contact with the pin 38. A corresponding protrusion is provided on the rocker arm 13. The protrusion 39 and its correspondence on the needle head 13. In this case, it rotates around its axis IjB, as a result of which the needle wheel 14 for the dyeing tape and the wheel 28 for the correction tape are retracted from the cassette 4 and respectively from the cassette 5. To release the rocker arms 12 and 13 to re-feed into the camera cassettes, the lever 36 is rotated clockwise, whereby the resistance force of the protrusion 39 and its correspondence on the yoke 13 disappears. If this happens, the kO1.1Speed 12 and 13 under the action of the springs 40 and 41 are rotated counterclockwise so that the needle wheels 14 and 28 grip eriferiyu coils of the ink and accordingly the correction ribbon to the receiver coils.
    A similar operation is performed by means of a mechanism (fig., In which the traction tires 43 and 43 are connected by axles 18 and 31 to the needle wheels 14 and 28 on the box) and are 12 and 13. The traction tires 42 and 43 have holes 44 and 45, which are jointly mounted on the knee of the hinge 46. The hinge 46 is located so that the shaft 47 is rotated around the horizontal axis 48 by means of the pull 47. The ha ha 47 is connected to the control lever 49, which is mainly carried beyond the size of the machine.
    During typewriter operation, the cassette holder 3 is controlled so that it sets the ink ribbon to two different heights relative to the printing position. The lift height is controlled by the cam follower 50 (FIGS. 7 and 8 meshing with the cam 22. The profile of the cam 22 (FIG. U has four protrusions, namely two large projections 51 and one of the middle projections 52. The difference between the heights the protrusions can be chosen so that in relation to the lowest point 53 one protrusion is twice as large as the other.As a consequence, when the cams “go”, the pusher 50 pushes towards a larger protrusion than when raiding, the pusher to the middle protrusion, respectively the red ribbon is transported on double If the DRA of;. Other desirable ratio at which, e.g., the ink ribbon in the inoperative position to be lowered even below the lowest point on the cam can be made even smaller actual selection cam lobes naturally depends on parameters.
    . dimensions of the device for drawing the dye tape into which it is embedded.
    Another important relation related to the size of the protrusions of the cam 22 is that the dimensions of the pusher 20 (Fig. 6), the stubs 19, the lever 17 and the needle wheel 14 are chosen so that the difference between the lowest point 53 and the highest the protrusion 51 on the profile of the cam 22 constitutes the full increment of the stretch of the dye tape. The ratio between the lowest point 53 and the middle protrusion 52 is not critical, so smaller protrusions cause only a part of the tape's increment, as well as because the hook 16 is inserted into the holes 15 on the needle wheel 14. The part of the increment is made during the passage - a smaller projection, and the hook 16 during the subsequent passage of the larger protrusion 51 falls again into Tfo and the transport movement is not made until the projection of the cam 22 reaches the equivalent of the preceding smaller protrusion 52. Then the yoke 12 is shifted far enough to bring the hook 16 into engagement with the leading edge of the hole 15 and move the needle wheel 14 to the remainder of the increment of the draw. To install the cassettes 4 and 5 into the flap control device 49, the control lever 49 (Fig. 2 / and, accordingly, the lever 36 (Fig. 9) rotate their axes in such a way that the boxes 12 and 13 are pulled back. Then the cassettes 4 and 5 are inserted into the cassette holder 3. The lever 49 and, accordingly, the lever 36 return to its original position, as a result of which the rocker arms 12 and 13 can re-enter the holes provided in the cassettes 4 and 5, so that the needle wheels on both rocker arms 12 and 13 may capture the periphery of the pickup coils, or, if the ink or the corrective flap It is already wound on the coils — the periphery of the pulley of the paint roller and, accordingly, of the pulley of the correction tape. The tension is now completed and the typewriter is ready for operation. With each keystroke, the main shaft 27 by means of a cyclically operating drive mechanism makes one complete turn. This also rotates a pair of cogs 23 with gear wheels 25 and 2. Together with the gear wheel 26, the cams 22 and 35 fixed to it also rotate (Fig.7 and 8 /, or ONE only cam 22 (FIG. 9 ). The cam follower 20, designed to pull the dye tape in accordance with the profile of the rotating cam 22, is reciprocatingly powered KOJ3e6aHHe and through the rod 19 rotates the lever 17 around its axis 18 and hooks the hook 16 with the holes 16 in the needle wheel 14 thereby turning the needle wheel to an incremental part (figs. 4 and 8). When the next mark was printed, another protrusion of cam 22 was conducted past the pusher 20, which leads to the repetition of the described operation, and only the magnitude changes by the angle by which the lever 17 rotates. It follows that during the second cycle, the needle wheel rotates through a full step red tape. To install the typewriter and, in particular, the device for drawing the dye tape into the correction mode, the back part of the cassette b is manually pressed down, as a result of which the cassette 4 touches and the cassette holder 3 rotates around the pivot axis of the cassette holder. In this position, the cassettes 4 and 5 can be held manually, or can be fixed with locking elements 54 and 55. If the cassette holder 3 tilts on its axis, the cam 35 entering the drive of the correction tape is engaged with the protrusion 34 of the pusher 33. The subsequent printing cycle, the ha 32 shifts together with the pusher 33 and causes the yoke 29 to rotate around the axis 31, as a result of which the needle is. the wheel 28, belonging to the stretch of the correction tape, performs a part of the turn corresponding to the full step of the adjustment tape. If the cassette holder is fixed in the upturned position, and the correction tape is also after the impact of the lettered element. It is in the printing position, then unlocking can be carried out through a special, cyclically working mechanism located nearby. Fixing edge 56. (Fig. 9 is located on the cassette holder 3. With the locking face 56, the locking element 55 engages, which is pivotally supported by the spring 57 on the axle 58 fixed on the frame 1. The locking element has a rocker cam push rod 59 terminating in the plane 60 cam pusher. The plane 60 rotates clockwise if the cassette holder is 3 turned and moves the locking face 56 forward. This movement of the face 5 € permits the locking element 55 to turn over the edge 56 and hold it to the side position until the locking element 55, due to the impact of the profile of the cam 61, rotates clockwise and at the same time unlocks the face 56. As soon as the face 56 is released, the cassette holder 3 returns to its original position and is thus ready to rise during the subsequent printing cycle to the position in which the dye tape is set for printing. If a correction tape and dye tape are used, the corresponding empty cassette is removed
    And replaced by a new one. The discharge operation, in the main, is the same as with the described charging, with the rocker arms 12 and 13, on which the needle wheels 14 and 28 are pulled back, while the cassettes 4 and 5 are removed from the cassette holder 3.

    The actions have advantages compared with the use of cassettes for dyeing tape and, respectively, corrective tape, which have receiving coils with a rigid axis, in which uniform drawing steps are achieved by directly driving the periphery of the coil of tape and, accordingly, the coil pulley.
