Considering incorrect insertion of the C cassette into the F cassette 1 to holder 6, for example, if the C cassette 2R is in the normal orientation (with the front lid facing forward) and the F cassette holder 6 is
In this case, the C cassette 2R and the bent portion 47. Since the center guides 214 are in contact with each other, it cannot be inserted deeper than in this figure.

Similarly, even if the C cassette 2L is pushed in while tied to the left side, the C cassette 2L cannot be inserted because it comes into contact with the bin 32 and center guide 214 of the drawer arm R17, respectively. Also, when the C cassette 2C is pushed in from the center of the F cassette holder 6, the center guide 214 and the C cassette 2G come into contact with each other, preventing insertion. Furthermore, even if the F cassette holder 6 starts moving with the C cassette inserted incorrectly as described above, the tape pull-out arm R1
7 is a lighthouse escape hole 2 formed in the F cassette holder 6
15, when the F cassette falls vertically, the tape pull-out arm R17 comes into contact with a lighthouse (not shown), making it impossible to fall vertically.

However, there is no problem when inserting the C set in the normal direction, but if the C cassette 1-2 is pushed in the longitudinal direction, as shown by the two-dot chain line in the figure, for example,
Since there are no obstacles, the C cassette 2 can easily enter deep into the apparatus, resulting in the problem that the C cassette 2 cannot be taken out of the apparatus.

In order to solve this problem, the present invention is provided with a first restricting means that prevents the C cassette 2 from being inserted into the F cassette holder 6 in any orientation. be. The first regulating means will be explained below.

In FIGS. 16 and 1F, reference numeral 207 denotes a rotating cover constituting the first regulating means, which is bent in an L direction so as to connect the left and right sides of the F cassette holder 6.
8, it can be rotated in the direction A or B in the figure. Further, the rotating cover 207 has the same center of rotation as the front cover 1' of the F cassette 1, and is shaped so as to wrap around the front cover 1', that is, not to come into contact with the inserted F cassette 1. Therefore, when the C cassette 2 is inserted into the F cassette holder 6 as shown in FIG. On the other hand, when the F cassette 1 is inserted into the F cassette holder 6 as shown in FIG.
I was able to insert it without any problem without making contact with 7, and then F
When the cassette 1 is horizontally moved and then vertically dropped and the front cover upper' is rotated and opened, the rotating cover 207 is also rotated together to obtain a problem-free F cassette mounting operation.

(Second restriction means) By the way, when the F cassette 1 is installed in the predetermined position in the device in this way, the C cassette 2 is inserted from the second insertion opening 204 as shown by the broken line in FIG. 17(b). If this occurs, the second motor (not shown) of the second cassette transfer means (not shown) is immediately driven to eject the C cassette 2 from the apparatus. Therefore, when the F cassette 1 is already installed, the C cassette 2 is inserted into the second insertion slot 204.
It cannot be installed inside the device even if it is inserted from the inside. These configurations are the second restriction means.

(Third regulatory measure) Next, the third regulating means will be explained using FIG. 18.

Note that FIG. 18 shows the state when the C cassette 2 is installed. That is, the C cassette 2 is inserted into the second insertion slot 204.
After inserting from the second cassette 1 to the transfer means (not shown)
is driven to move the connecting holder 11 from the second position shown by the broken line in the figure to the J2 position shown by the solid line, and then the first cassette transfer means (not shown) is driven so that the cassette is mounted on the F cassette holder 6. The C cassette holder 1o is moved horizontally and vertically to a third position indicated by a solid line in the figure, and the C cassette 2 is mounted at a predetermined position within the apparatus.

By the way, in the figure, a bent portion 209 is formed on the connecting holder 11 held at the first position, and this bent portion 209 is formed in the first position. It is configured so that it can come into contact with the first cassette door 205 of the insertion slot 203. Therefore, even if you try to insert the F cassette 1 or the C cassette 2 from the first insertion slot 203 with the C cassette 2 installed at a predetermined position in the device as shown in FIG. 209, each cassette cannot be inserted into the device. ...Third regulatory measure.

(Fourth restriction means) 210 is a locking member constituting the fourth restriction means;
211 is a rotating shaft, 212 is an elastic body, and 213 is a stopper. Here, the locking member 210 is attached to the second cassette door 2.
It is placed in a position that does not interfere with the rotation locus of 06.

Explain the operation.

Now, the connection holder 11 has descended to the first position, and the C cassette 1
2 is attached to a predetermined position within the device.

Here, the locking member 210 is moved by the elastic body 212 at A in the figure.
Although it rotates in the direction, it remains stationary at the position where it contacts the stopper 213. Therefore, in this state, the second insertion port 204
Even if an attempt is made to insert another C cassette 2 (indicated by the dotted chain line in FIG. 19), the front surface of the C cassette 2 and the lock member 2
10, the C cassette 2 cannot be inserted into the device.

Note that the connection holder 11 is moved from the first position to the second position i! in front of the device. ! When the locking member 210 is raised to a position (indicated by a broken line in the figure), the locking member 210 contacts the upper plate of the magnetic recording/reproducing device 200 and rotates in the direction B about the rotating shaft 211. The fourth restricting means is applicable not only to magnetic recording and reproducing devices of the insertion rotary type, but also to magnetic recording and reproducing devices having at least one insertion port. In particular, the first restricting means for preventing the insertion of the C cassette 1 into the F cassette holder mentioned above is
Can be used in magnetic recording and reproducing devices exclusively for cassettes.
And it has a tremendous effect.
