    专利说明:

    The invention relates to the accumulation of information, namely to magnetic tape cassettes. A vintage tape cassette containing cores mounted & foamy in a box-like housing with the possibility of free rotation and placed inside the pyneHOB / magnetic tape 1. The known cassette has a relatively simple design, however; it requires a significant amount of energy to rewind a magnetic tape from one roll to lyyrou. Also known is a tape cassette containing cores mounted in a box-like case with free rotation and placed inside rolls of magnetic tape, each of which is connected by opposite ends with a lubricating coating of plastic plates made with round holes in which the core axes are located. This cassette allows you to save on energy costs for rewinding a tape from one roll to another 2J. The disadvantage of this cassette is the considerable unevenness of the lubrication of the magnetic tape. The purpose of the invention is to increase the uniformity of magnetic tape lubrication. This is achieved by the fact that the lubricating graphite coating is made in the form of strips arranged parbol}} The lines of symmetry of the circular holes of the rubber-mass plates are made of corrugated plates, the bands of the lubricating graphite coating are placed on the tops of the protrusions of the corrugated plastic plates, the opposite sides of which are antistatic coating. FIG. 1 shows a tape cassette; in fig. 2 - the same, option. The proposed casudet contains heart boxes 1, installed in the case-like body 2 with the possibility of free rotation and also located inside the rolls of the 3 magnetic tape. Each of the 3 rims, magnetic tape mated with opposite ends with a lubricating graphite coating l 4 plastic plates 5, filled with circular holes 6, in which the axes of cores 1 are located. The lubricating graphite coating 4 is made in the form of strips parallel to the line of symmetry of the circular holes 6 plastic plates made of corrugated. At the same time, the strips of the carbon graphite coating 4 are placed on the tops of the protrusions of the corrugated plastic plates 5, the opposite sides of which are made with an antistatic coating. In the bundled cassette, the ends of the rolls, 5 3 magnetic tapes in the process of rewinding the last contact with the lazy graphite coating 4, located only on the tops of the protrusions of the corrugated plastic plates 5. This leads to JQ
    Improves the uniformity of graphite lubrication of the magnetic tape. In addition, the implementation of the lubricating graphite coating 4 in the form of strips provides a reduction in the amount of excess graphite contaminating the magnetic tape.
    The use of the invention, in addition to improving the uniformity of the lubrication of the magnetic tape, also provides a considerable simplicity of the cassette design.
