    The invention relates to the technical field of magnetic tape cassette components and the like and specifically to a magnetic tape backing leaf spring particularly for magnetic tape cassettes. The technical problem was to provide a leaf spring which would perform in an optimum way in the tight guide of a tape. The solution to the problem is provided by a magnetic tape backing leaf spring (1) comprising an elastically flexible reed element (2) defining by itself both supporting portions (2b) and a working portion - (2a) engageable directly with a tape (3) and being supported by the supporting portions (2b) in a projecting position from the positions of said supporting portions (2b), the working portion (2a) defining stepped zones (2c) with the supporting portion (2b) 'and being elastically deformable into an arcuate configuration in the operating position.

    The invention relates to an information storage technique and can be used in tape cassettes.
    The aim of the invention is to improve the operational parameters.
    Figure 1-3 shows the node clamp the magnetic tape, inserted into a tape cassette; 4, 5 shows the jaw assembly with a rigid magnetic screen; figure 6 is a flat scan of the spring strip.
    The device contains a spring element 1 in the form of a strip, in the central-15 zone of which there is an extruded protrusion 2 With holes 3 and notches 4 along the edges supporting part 5 with mounting surfaces 6 and projections 7 located between the side surface 8 of the protrusion 2 and the end of the element magnetic screen 9, supports 10 and P.
    In order for the pressing surface of the protrusion 2 to deflect the arcuate-25 but without concentrating the pressure on the central part of the magnetic head 12, the pressing surface of the protrusion 2 is weakened by holes 3 and notches 4 along the edges in order to reduce locally the bending resistance press the magnetic head 12 of the magnetic tape 13. In one embodiment (Fig. 3), the side surfaces 8 of the protrusion 2 converge to the magnetic tape 13 so that the working part of the assembly protrudes. This allows you to provide an accurate arcuate arrangement of the working part of the assembly - without pressure on the middle of the magnetic head 12. 40
    In order to attach the spring element 1 to the supports 1 O and 1 I, its mounting surfaces 6 comprise protrusions 7, obtained by deep drawing and allowing the spring element 1 to move 45 without restriction and set to the position of the best stress balance. The spring element 1 may be made of any appropriate flexible metal 50 or plastic material having a low coefficient of friction or may have an appropriate coating on the extruded protrusion 2.
    It is recommended to apply a magnetic screen 9 on the spring element 1, which can be made either very thin and flexible, or rigid and narrow. The magnetic screen 9 can be used in combination with a magnetic screen 14 located away from the magnetic tape 13.

    Claims (4)
    [1]
    1. The knot of a clip of a magnetic tape containing a spring element in the form; strips with a protruding pressure surface in its central zone, as well as two supports, between which a spring element is located, the mounting surface of each of the ends of the spring element encompassing the cylindrical surface of the corresponding support, which, in order to improve operating parameters, the surface is made in the form of a corresponding extruded protrusion in the spring element, and each of the parts of the spring element located between the stepped surface in The protrusion and the corresponding support are made in height and tapering towards the support.
    [2]
    2. A knob as claimed in claim 1, characterized in that the mounting surfaces of the spring element comprise protrusions and cover the respective surfaces of the supports with the possibility of rolling.
    [3]
    The knot according to claim 1, which differs from the fact that the spring element contains holes and cuts along the edges made in its central zone.
    [4]
    4. The knot of Clause 1, about tl. And h and y - and with the fact that the stepped surfaces of the protrusion in the central zone of the spring element lie in converging planes one to another.
