The drive mechanism for the cassette holder 4 described above is provided on the left and right inner side surfaces of the cassette deck 1.

The present invention will be explained in detail below. In FIG. 3, when the motor 10 is rotated, the worm 11 is rotated. As a result, the worm wheel portion 12a of the relay gear 12 rotates counterclockwise, and the spur gear portion 1?of the relay gear 12 rotates counterclockwise. A drive gear 13 connected to C rotates clockwise around a support shaft 13a.

Therefore, the drive lever 14 fixed to the drive gear 13 also rotates clockwise about the support shaft 13a. Here, since the main rotating body 15 is engaged with the good hole portion 14a and the guide groove 8a by the driving pin 15a, the main rotating body 15 is rotated by approximately 340 rotations of the driving lever 14 clockwise. It rotates about 53" counterclockwise around the support shaft 9a. As a result, the rotated body 16 that is interlocked with the main rotating body 15 rotates around the boulder.

Since the arc portion is formed as an arc centered on the support shaft 9a, the support shaft 9a remains stationary during the above-described operation, and therefore the slide plate 9 also remains stationary.

Furthermore, the cassette lock lever 11 prevents the cassette 5 from falling during this operation. Through the above-described operations, the cassette loading device shifts to the state shown in FIG. 5. Fifth
The motor 10 rotates from the state shown in the figure, and the drive lever 14
When the drive bin 15a rotates about 520 clockwise, the drive bin 15a moves about 35 an horizontally to the left along the guide groove 8a.

Main rotating body 1 again! Since the support shaft 9a, which is the center of rotation of the slider 1, is implanted in the slide plate 9, the support shaft 9a, like the slide plate 9, is also movable only in the horizontal direction, as described above.

Accordingly, (by the horizontal movement of the drive bin 15a, the main rotating body 1
5 and the slide plate 9 move approximately 35 m+$ in the horizontal direction without rotating. At this time, Boldashi l? The cassette holder 4 connected to the slide plate 9 by the foot 9d also moves approximately 35 g horizontally to the left without rotating. Through the above operations, the cassette mounting device shifts to the state shown in FIG.
0, the guard panel 5a opens, and the cassette 11
It becomes possible to draw out and store the magnetic tape from the 10th copy. In the state shown in FIG. 6, erect viewing of the cassette 5 is realized. Incidentally, the transition from the state shown in FIG. 6 to the state shown in FIG. 3 can be realized by rotating the motor 10 in the opposite direction by an operation completely opposite to that described above.

As described above, according to this embodiment, when the J set 5 is inserted into the cassette holder 4, it is inserted from a position that allows it to be inserted slightly diagonally downward, and when the cassette 5 engages with the reel stand, the cassette 5 is erect and transparent. The mechanism for moving the cassette holder 4 to the position where it can be moved can be realized with a small number of parts, and the mechanism is extremely simple, driving only the main rotating body 15, and the cassette holder 4 supported by the slide plate 9 The holder 4 has excellent positional accuracy in the vertical, horizontal, and horizontal directions. Furthermore, by placing the supporting part of the numbered cassette holder 4 on the slide plate 9 in a position close to the straight line passing through the current 5 and the center of gravity of the cassette holder 4, the drive source when the Caret holder 4 makes a predetermined movement can be used. The load will be extremely small. By appropriately selecting the drive locus of the drive bin 15a protruding from the main rotating body 15, it is possible to cause the cassette holder 4 to perform various movements including rotation and substantially parallel movement. In addition, by moving the cassette holder 4 as described above, the insertion of the cassette 5 can be done very easily, and the cassette 5 after being installed is as good as the older brother.The quality of the product is also greatly improved, which has practical effects. There is something big about it.
