SU667167A3 - Cassette for magnetic tape - Google Patents

Description

one

The invention relates to the field of magnetic recording, in particular to the storage of information.

Magnetic tape cassettes are known, containing two freely rotating cores, on which are paired with coils of magnetic tape. ,

However, the movement of the magnetic tape in them is uneven.

The purpose of the invention is to reduce the irregularity of the movement of the magnetic tape.

The goal is achieved by the tel that the cassette contains a lever, one surface of the free end of KOtopO is matched with the outer coil of the magnetic tape roll, and the shaft is with (The magnetic tape arriving at it, the lever is made with two projections coupled with the edges of the magnetic leita

Figure 1 shows a compact cassette with pivoting levers as guiding elements for a magnet tape, top view; figure 2 - lever;

Rectangular base I of a compact cassette; On the front 6f “psbft surface, there are 2 through holes 3-5 for magnetic heads and punching rollers. Holes 6 and 7 are designed to pass the capstan and Dowel Guides for the magnetic tape. Through the bore 3, there are felt clamping elements 8. On the coils 9 and 10, installed with the possibility of rotation. On the base 1, there is a magnetic tape. 11 is folded into rolls 12 13. nta 11 rounds the guiding rollers G4 and 15, mounted on the base 1, near which, inside the loop formed by the magnetic tape, pins 16 and 17 are inserted in the base of the cassette for the hinge fastening of the levers 18 and 19. One surface of the free end of the front end is matched to the outer side of the magnetic tape. Levers 18 and 19 are slightly bent and mounted symmetrically to the R transverse center axis 20 of the base. The free ends of the levers, at the height of the longitudinal middle axis 21, abut on the outer surfaces of the tines 12 and 13. The free ends of the levers 18 and 19 are provided with ledges 22 in the form of protrusions 23 and 24, which reduces the uneven movement of the tape.
