    This invention relates to the accumulation of information, in particular to tape cassette devices.
    The purpose of the invention is to simplify the cassette design. -
    Fig. I depicts a variant of a cassette device for moving a magnetic tape; FIGS. 2 to 7 show different types of modification of the flexible electrically conductive element of the current collector in the first embodiment; on Fig and 9 are different types of the second variant of the device with magnetic tape; 10-12 - different types of his third va
    ryant.
    The cassette device of the first, second and third versions contains an electrically conductive cylindrical guide element 1, made of an electrically conductive material, for example, metal tal, conjugated on a part of a circular cylindrical surface with a base of magnetic tape 2, and a flexible electrically conductive element (current collector). In this case, the cylindrical guide element 1 is installed in the cassette 3 with the possibility of fitting its concentric cylindrical hole 4 on the locating pin 5 of the cassette device connected to the source of the reference potential. one
    According to the first embodiment of the cassette device, the flexible electrically conductive element is made in the form of plate springs 6 of electrically conductive material, for example, of metal. The leaf spring 6 has at one end the first and second tabs 7 and 8. The first tongue 7 of the leaf spring 6 is tangentially joined directly to the circular cylindrical surface of the conductive guide element 1. The second tongue B of the leaf spring 6 is conjugated to a part of the circular cylindrical the surface of the cylindrical guide element 1 through the magnetic tape 2. The second tongue 8 of the plate spring 6 is located tangentially to the working layer of the section of the magnetic tape 2 joined by its base with part of the circle oic cylindrical surface electric conductivity Nogo nap.ravl cylindrical guide member 1. At the second end of the leaf spring 6 is mounted on the wall of the cassette 3.

    The plate spring 6 in the first embodiment of the cassette device may have a third tongue 9 at the end on which the first and second tongues 7 and 8 are placed. The third tongue 9 of the leaf spring 6 is tangentially aligned directly with the circular cylindrical surface of the cylindrical guide element 1 (Fig 2 and 3).
    The first tongue 7 of the leaf spring 6 can also be mated to a part of the circular cylindrical surface of the cylindrical guide member 1 through the magnetic tape 2. In this case, the second tongue 8 of the leaf spring 6 can be mated directly to the circular cylindrical surface of the cylindrical guide element 1 (Fig .4 and 5).
    In addition, the plate spring 6 can be made with U-shaped legs 10 and with a fixing foot 1, and the wall of the cassette 3 is equipped with an I-shaped holder I2 and a locking protrusion 13 (Fig. 6 and 7). At the same time, the other end of the leaf spring 6 is mated with the locking protrusion 13, and the u-shaped legs 10 are mounted on the horseshoe-shaped holder 12 of the wall of the cassette 3, mated with the fixing leg 11.
    Plate spring 6 can be performed with a locking protrusion 14, and the wall of the cassette 3rd pocket 15 (Fig. 2-5). At the same time, the other end of the leaf spring 6 and its locking protrusion 14 are installed in the pocket 15 of the cash register wall 3.
    According to the second embodiment of the cassette device, the flexible electrically conductive element is made in the form of a twisting spring 16 of electrically conductive material, such as metal. The first end 17 of the twist spring 16 mates tangentially directly to the circular cylindrical surface of the electrical conductive cylindrical guide element 1. The second end 18 of the twisting spring 16 is located tangentially to the working layer of the magnetic tape section 2 that mates its base with a portion of the circular cylindrical surface conductive cylindrical guide element 1.

    The helical portion 19 of the spring-16 twist is reinforced inside the cartridge 3.
    According to the third embodiment of the cassette device, the flexible electrically conductive element is made in the form of an L-shaped leaf spring 20 of electrically conductive material, for example, of metal. The first end of the 21 L-shaped leaf spring 20 is mated directly to the end surface of the electrically conductive cylindrical guide member 1. The second end of the 22 L-shaped leaf spring 20 is conjugated with part of the circular cylindrical surface of the conductive cylindrical guide element 1 through the magnetic tape 2. The second end of the 22 G-shaped leaf spring 20 is mated to the working layer of a section of magnetic tape 2 mated to its base with a part of the circular cylindrical surface of the guide element. At the same time, the L-shaped plate spring 20 is fixed on the cheek of the cassette 3.
    The device in the first, second and third options works in the following way.
    - In the process of moving the magnetic tape 2, an electrically conductive cylindrical guide element, 1, which is in constant electrical contact with the pin 5 of the cassette device, rotates. In the process of moving the magnetic tape 2, an electrostatic charge of its working layer occurs. However, electric charges flow from the working layer of the magnetic tape 2 to the installation pin 5 of the cassette device, which is under the reference potential through an electrically conductive cylindrical guide element 1 and a flexible electrically conductive element made in the form of a plate-shaped fipy reel 6 or spring 16 twisting an, or -label plate spring 21.
