    A high performance self threading tape transport apparatus is packaged within a stand alone 19 inch wide frame. The tape transport apparatus includes a removable file reel and a machine reel. The removable file reel and the machine reel are arranged diagonally with a gravity assisted tape threading path. A single capstan is positioned adjacent the tape threading path with a pair of vacuum chambers situated one on each side of the capstan. The vacuum columns are offset relative to each other but incline to the tape threading path. A processing station including a magnetic transducer, is displaced relative to the tape threading path and operates to read magnetic data from the tape or to write magnetic data on the tape.

    one
    The invention relates to the field of accumulation of information, namely, entropy mechanisms.
    A tape mechanism is known, which contains the input and output nodes, which are located in the input and output coils with magnetic tape i.
    The tape mechanism also has a relatively simple design, but does not allow for sufficient uniformity of the speed of movement of the magnetic tape.
    Also known is a tape mechanism containing the feed and take-up nodes, the axes of which are placed in the feed and take-up coils with magnetic tape, the first guide roller located on the extension of the entrance wall of the first vacuum rectangular pocket, installed on opposite sides of the block magnetic heads between the exit wall of the first vacuum rectangular pocket and the drive shaft, p-located at the extension of the entrance wall of the second vacuum rectangular pocket, on the favor of the second wall which is a second
    guide roller, guide element, made with nozzles, and controlled pressure element 2.
    This tape mechanism provides a relatively high uniformity of the speed of movement of the magnetic tape. The disadvantage of such a tape mechanism is that
    Simplifying its maintenance results in a significant increase in size.
    The purpose of the invention is to reduce the size while simplifying
    5 service.
    The goal is achieved due to the fact that the axes of the feeding and receiving nodes are located on the diagonal line of the rectangular plate, the exit wall
    The first vacuum rectangular pocket and the entrance wall of the second vacuum rectangular pocket are reinforced at an acute angle to the edge of the rectangular plate with an inclination in the side of the feeding unit, controlled by a pressing element located opposite the drive shaft in a guide element, the guide surface of which is opposite first and second guide rollers under the sharp
    globular to nozzles that are capable of securing the movement of the magnetic tape in the direction of the receiving unit during refueling, the acute angle of the exit wall of the first vacuum rectangular pocket to the edge of the rectangular plate more The surface of the guide element is straight-line between the first guide roller and the drive shaft and arcuate between the drive shaft and the second guide roller.
    The drawing shows one of the possible variants of the proposed tape drive mechanism.
    The proposed tape drive mechanism contains feed and take-up nodes 2 and 3 mounted on a rectangular plate 1, the axes 4 and 5 of which are placed in the supply and take-up coils 6 and 7 with magnetic tape 8, the first guide roller 9 located on the extension of the input roller the walls 10 of the first vacuum rectangular pocket 11, and the vacuum guide elements 12. In this case the vacuum guide elements 12 are installed on opposite sides of the block 13 of the magnetic heads between the exit wall 1 of the first vacuum rectangular pocket 11 and lead they shaft 15. The drive shaft 15 is disposed on the extensions of the front wall 16 of the second vacuum rectangular pocket 17 on the extension wall 18 whose output is a second guide roller 19.
    In the proposed tape drive mechanism, the axes 4 and 5 of the feeding and receiving nodes 2 and 3 are located on the diagonal line of the rectangular plate: 1, and the control unit 1 of the pressing pressure element 20 is located opposite the drive shaft 15 in the guide element 21, made with nozzles 22. The guide surface of the guide element 21 is located against the first and second guide rollers 9 and 19 at an acute angle to the nozzles 22, mounted to enable movement of the magnetic tape 8 to the side of the receiving unit 3 when refilling it.
    In the Ribbon Mechanism, the outlet wall 1-4 of the first vacuum rectangular pocket 11 and the entrance wall 16 of the second vacuum rectangular pocket 17 are reinforced at acute angles to the edge of the rectangular plate 1 with an inclination in the direction of the feeding unit 2, and the sharp is the angle of inclination the outlet wall 14 of the first vacuum rectangular pocket 11 to the edge of the rectangular plate 1 is greater than the acute angle of inclination to it of the entrance wall 16 of the second, vacuum rectangular pocket 17, the guide surface of the guide element 21 is linear between the first guide roller 9 and the drive shaft 15 and arcuate between the drive shaft 15 and the second guide roller 19.
    In the proposed mechanism, in the process of recording or reproducing the rotation of the drive shaft 15, it is converted into a translational movement of the magnetic tape 8 wound up from the supply coil b and wound onto the receiving coil 7. During the refueling process, the end of the magnetic tape 8 from the supply coil 6 the air supplied by the nozzles 22 enters the receiving coil 7 and adheres to it due to the vacuum.
    The use of a tape drive mechanism makes it possible to significantly reduce the size while simplifying its maintenance.
