    • 专利摘要:
    A relatively narrow printing head scans across photosensitive material and in one scan generates a line of characters thereon. Digital control signals selectively illuminate the LEDs formed within a matrix thereof. A flexible loop of flat fiber optic filaments having their input ends coupled to the LEDs and having their output ends positioned within the print head, enables the use of a relatively small number of fiber optic filaments and yet provides for extremely high-speed recordation of the characters upon the film which contacts the print head. After a line has been photographically recorded, the film is stepped in a direction perpendicular to the direction of scanning of the print head and another line is recorded. An inexpensive and highly accurate print head carriage is disclosed, along with a unique belt drive for driving the carriage without inducing torque therein, owing to possible misalignment of the drive belt.

    and a reversible electric motor for driving one of the pulleys, wherein a finger is fastened to the carriage with a shoulder at the end, and there are holes at the ends of the belt transport body, by means of which it is fixed to the finger of the carriage.
    The invention relates to systems for forming graphic images, in particular, alphanumeric printing devices that can be used in photocomposition.
    The goal of the invention is to increase the reliability of the device.

    1065 i
    5. Device on PP. 1-4, characterized in that the carriage is mounted on two guides and has an L-shape, in parallel with each other parts of which rollers are mounted to interact with the guides, and these sections are installed with the ability to move one to another due to elastic deformation body carriage for removal of the carriage guides.
    6. The device according to paragraphs. 1 - 5, characterized by the fact that three rollers are mounted on the carriage, and the rollers are grooved.
    7. The device according to paragraphs. 1 - 6, characterized in that the printing head is mounted on the carriage by means of a carrying lever that is spring-loaded in the direction
    to the cavity of the location of the printed photosensitive mater 4, the switch master unit 5 and the master block 6 with parallel input for binary data, the print head 7, the displacement mechanism 8 (shown conventionally) of the photosensitive material 9 and fiber optic fibers 10 fixed by its output HbiN; n ends 1 1 in the print head 7 and connected with its input ends 12 to the corresponding light emitting elements of the matrix 1.
    In an experimental sample of a device, a matrix of 1 fibers consists of 16 columns with eight LEDs each, thus providing 128 separate light channels.
    The device also contains a mechanism for moving the printhead 7 in the direction perpendicular to the direction of re-moving the photocell material 9, and the optical fibers attached to each other in a flexible organ, for example, in the form of a tape 13, located in the form of a loop.
    Their end 1 1 is placed in the print head 7 at least in one row in the direction of movement of the photosensitive material 9. In the experimental sample of the device for recording, the ends of the optical fibers and the recording head are arranged in two rows of 64 in each staggered in order to prevent the parasitic passage of light and, thus, to ensure the overlapping of point sources of light. To increase durability, the flexible member of the light guides 10 comprises a support substrate of flexible material.
    The mechanism for moving the printhead 7 has a carriage 14 placed across the transport direction of the photosensitive material 9 and parallel to the plane of its arrangement the guides 15 and 16, on which the carriage 14 is mounted, and the carriage drive containing the belt unit 19 located on the jaws 17 and 18 and a reversing motor 20 for driving the pin 17. To connect the carriage 14 to the transport unit 19 on the carriage 14, the pin 21 is fixed with a shoulder 22 at the end, and at the ends 23 and 24 of the transport member 19 there are openings 25 and 26, by means of which it is fixed on the finger 21 of the carriage 14.
    The most expediently carriage 1 is C-shaped, with rollers 29-31 mounted in parallel sections 27 and 28 for engagement with guides 15 and 16. Sections 27 and 28 of carriage 14 can move one to another due to elastic deformation body carriage for removal of the carriage 14 with the guides 15 and 16.
    In order to ensure the guaranteed contact of the print head 7 with the material 9, the print head 7 is mounted on the spring-loaded spring 32 to the lever 33, which is hinged to the body of the carriage 14.
    Moreover, it is expedient that the guides 15 and 16 have a cylindrical shape, and the rollers 29 have 31 grooves so that they are held on the guides 15 and 16 without backlash. It is necessary for
    54 "
    using the device in a photo dialer machine. Using the three-roller system for installing and fixing the carriage 14 on the guides 15
    and 16 prevents the carriage from sticking when moving along guides when the manufacturing tolerances are changed.
    The device works as follows.
    When moving the print head 7 from the drive of the carriage 14, the material 9 is scanned to record a string of characters.
    After the character string has been written, the mechanism B of moving the photosensitive material 9 carries out the stepwise movement of the material 9 in the direction perpendicular to the direction
    scanning the print head 7, and the carriage 14 with the print head 7 is returned to its original position to carry out the process of recording the next line.
    The speed of receiving optical signals is very high, directly proportional to the scanning speed. This action is provided by a source of 2 gating pulses, which controls the operation of the counter 3. The source of 2 gating pulses may include a shut-off means with a photocell that is mechanically connected to the drive of the belt unit 19. Other devices can be connected to the motor shaft 20 a series of pulses having a frequency proportional to the speed of movement of the transport organ 19. In the experimental sample, the device is. The facilities use a synchronous motor to drive the print head 7. A source of 2 gating pulses, in addition to controlling the counter
    3, also activates the division and subtraction counter 34, which controls the operation of the unit specifying the sequence of operation of the unit 35, calling by
    the control circuits 36, the predetermined rotational speed of the engine 20.
    The print head 7 has a relatively small number of light guides. However, the location of their ends in
    head 7 allows you to generate a string of characters across its height, Thanks to the above mounting of the ends of the transport body 19 on
    the carriage 14 is possible to quickly (by loosening the tension of the transport body 19), detaching from the carriage 14.
    Since the number of optical fibers 10 in the proposed device is significantly less than the number of optical fibers in known devices, the probability of failure in the operation of optical fibers is much less. However, if such failures had occurred, the printing head 7, the matrix 1, would emit light. of the optical fiber and the tape 13 of the optical fibers can be easily removed from the device as one piece and replaced with a new assembly (the matrix of light-emitting elements 1 - the tape П S - - "н" "of the optical fibers - printing
    In addition to use in a photo dialer, the proposed device can be used in 10 line-by-line telecopier systems, printing systems at the output of a computer, and so on.
    Obviously, the invention is not limited only to the constructive implementation described above.
