Abstract

The invention relates to a magnetic recording technique, in particular to tape recorders, and makes it possible to simplify the design of a cassette loading unit in a tape recorder. The device contains guides 15 in contact with the frontal plane of the cassette 11. Outside the area of the drive shaft 5, the guides are located at an acute angle to the cover 17 of the cassette receiver, and in the area of the drive shaft parallel to it. In this case, the axis of rotation 8 of the cassette receiver is fixed directly to the chassis. 4 il.

(57) The invention relates to a magnetic recording technique, in particular to tape recorders, and allows simplifying the design of a cassette loading unit in a tape recorder. The device contains guides 15, which are in contact with the frontal plane of the cassette 11. Outside the area of the drive shaft 5, the guides are located at an acute angle to the plate 1 7 of the cassette receiver, and in the area of the drive shaft they are parallel to it. In this case, the axis of rotation 8 of the cassette receiver is attached directly to the frame. 4 il.

The invention relates to instrumentation, and to the technique of magnetic recording, and can be used in tape recorders magnetic recording.

The purpose of the invention is to simplify the design.

FIG. I shows the proposed device without a cap, a general view; in fig. 2 - fixing the cassette receiver, working position; in fig. 3 - cassette receiver, intermediate position; in fig. 4 - the same, open position.

The device comprises a chassis 1, on which the front support 2 and the rear support 3 are installed, a fixing device 4 and a driving shaft 5, a spring 6, a bracket 7 with an axis of rotation 8, on which a spring-loaded cassette receiver 9 with a spring 10 is mounted. In the cassette receiver there is a cassette II, having front 12 and rear 13 edges and aperture 14. Guides 15 are installed on the cassette-receiver, in contact with the frontal plane of the cassette, elastic elements 16, cover 17 and protrusion 18. Guides 15 are made at an acute angle oi to the edge 17. 17. Close with position cus the network receiver cassette is spring-loaded to the front 2 and rear 3 supports by the elastic elements 16, and from the rear edge 13 side — by the spring 6 and takes position parallel to the cover 1 7.

 The device works as follows.

When released, the locking device 4 is released from the engagement with the protrusion 18 and the cassette receiver 9 begins to open by the action of the spring 10. Since the guides 15 are made at an acute angle to the cap 17 ,. then with the cassette. And they come into contact at a point closer to the drive shaft 5. Cassette II begins to move away from the front support 2-, while remaining on the rear support 3 due to the fact that the elastic elements 1 push the cartridge 1I to the rear support 3. In this case, the cassette is rotated

the direction opposite to the direction of rotation of the cassette receiver 9, and the opening of the cassette 1I moves along a circular arc. Due to this movement, the drive shaft 5 emerges from the hole 14.

In the loading position, the cassette 11 is guided along the guides 15 into the cassette receiver 9 and is pressed against the guides 15 by elastic elements 16. When the cassette 11 is closed, it is first rotated together with the cassette receiver on the axis 8 until it reaches the rear support 3. Subsequently 1 and the cassette receiver 9 continues to rotate on the axis 8 of the cassette on the side of the trailing edge 12 is in contact with the guides 15 at a point closer to the drive shaft 5. At the same time, the hole 14 moves along an arc, and the drive shaft 5 continues to Go to hole 14. The cassette receiver 9 rotates to the position when it is fixed by the locking device 4, and the front edge of the cassette 11 is mounted to the front support 2. Since the angular movement of the cassette from the moment the drive shaft 5 was inserted into the hole I4 to the position of the installation on the front support 2 small, then the drive shaft is inserted into the hole 14 without jamming

Claims (1)

Invention Formula A device for loading a cassette into a tape recorder containing a drive shaft and a cassette receiver located on the chassis with elastic elements and guides in contact with the base frontal plane of the cassette, a tape cassette holder, an axis rotated. nor the cassette receiver, located on the side of the drive shaft, of which it is read. so that, in order to simplify the construction, the guides are located at an acute angle to the krppka, with the smallest distance between the lid and the guides made from the side of the drive shaft, and the axis of rotation of the cassette receiver is fixed directly to the chassis.
