In the above description, the drive mechanism (t) for the cassette holder 4 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 A-arm 11 is rotated. As a result, the A-arm wheel portion 12a of the relay gear 12 rotates counterclockwise, and the drive gear 13 connected to the spur gear portion 12c of the relay gear 12 rotates about the support shaft 13a in the direction of rotation.

Therefore, the drive lever 14 fixed to the drive gear 13 also rotates in the time S1 direction about the support shaft 13a. Here, since the main rotating body 15 is engaged with the elongated hole 14a and the guide groove 8a by the drive pin 15a, the drive lever 14 is rotated at the time δ1.
By rotating approximately 250 times in this direction, the main rotating body 15 rotates approximately 410 times in the counterclockwise direction about the support shaft 9a. As a result, the rotated body 16 interlocked with the main rotary body 15 rotates approximately 1050 times clockwise around the small Lugussi 1 shift 9d. Therefore, it is supported by the cassette holder 4 or cassette boulder 4 that fixes the rotated body 16].
Similarly, the lock lever 17, cassette 5, etc. are rotated approximately 1050 degrees clockwise around the holder seat 1-96.
Cassette 5 stands upright. Furthermore, as mentioned above, the guide f
Since the arc portion of Fj8a is formed as an arc centered around the support shaft 9a, the support shaft 98 remains stationary during the following operations, and therefore the slide plate 9 also remains stationary. . Further, the cassette lock lever 17 does not allow the J: cassettes 1 to 5 to fall during this operation. Through the above-described operations, the caret 1 to the mounting device shift to the state shown in FIG. 5. State 1 in Figure 5) Motor 1

Since it is stepped, the support shaft 9a, like the slide plate 9, also moves only in the horizontal direction, as described above.

Therefore, due to the horizontal movement of the drive bin 15a, the main rotating body 15
The slide plate 9 moves approximately 35 mm horizontally to the left without rotating. At this time, the cassette 4 holder 4 connected to the slide plate 9 by the holder shirt 1-9d also moves about 35 mm horizontally to the left without rotating.

By the above-mentioned operation, the cassettes 1 to 6 are installed.
The state shifts to the state shown in the figure, the current 5 is crimped to the cullet support post 20, the guard panel 5A is closed, and the magnetic chip 7 can be pulled out and stored from the cullet frontage. . In the state shown in FIG. 6, erect perspective of the lenses 1 to 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 0 in the opposite direction by an operation completely opposite to the above-mentioned hoovering operation.
