3 to 6 show a tape cassette loading device,
FIG. 3 shows the state when the first tape cassette 11 is installed, and FIG. 5 shows a state in which the second tape cassette 12 is ready for installation, and FIG. 6 shows a state in which the second tape cassette 12 is switched from a state in which it is possible to install to a state in which the first tape cassette 11 is ready to be installed. is the first tape cassette holder.

31 is a holder drive arm; 32 is an upper adapter of an auxiliary member for storing the second tape cassette 12 in the first tape cassette holder 30; 34 is the same lower adapter;
3 directly stores the second tape cassette 12.

A second tape cassette holder for holding, 35 is a lower adapter lifting mechanism, 36 is a mechanical chassis, 37 is an upper adapter lifting mechanism, and 38 is a wireless remote controller for issuing operation commands to the main body 13.

This operation will be explained next. First, let's talk about installing the first tape cassette 11 into the main body 13. Since the door 16 is normally closed, be sure to press the cassette selection button 17 first to enter the first tape cassette mode. . When the tape cassette loading device 15 is in a state where the first tape cassette 11 can be loaded, the door 16 immediately opens to the state shown in FIG. It can be inserted. Then, when the first tape cassette 11 enters the first cassette holder 30 and is pushed to a predetermined position, the holder drive arm 31 automatically starts rotating, and the mechanical chassis 36 shown by the broken line in FIG. It is transported to a predetermined position above. In this state, various operations such as recording or reproduction can be performed. During this series of operations, the upper adapter 32, which is a related member for attaching the second tape cassette 12,
, lower adapter 34 , upper adapter lifting mechanism 37 , lower adapter lifting mechanism 35 , and second tape cassette holder 33
As shown in FIG. 3, the tape cassette holder 30 remains housed at a predetermined position below the first tape cassette holder 30 so as not to interfere with the operation of the first tape cassette holder 30.

Next, the case where the second tape cassette 12 is installed will be explained. First, like last time, press the cassette selection button 17 to enter the second tape cassette mode. At this time, the operation can be performed by pressing the button directly by hand, or, as shown in FIG. 4, a command can be given using a wireless remote controller 38 that uses infrared rays or the like. In either of these methods, when the command to select the second tape cassette is received, the door 16 will automatically close once (however, if it was originally closed, it will remain in that state). In this state, the tape cassette mounting device 15 performs a switching operation from the first tape cassette mounting state to the second tape cassette mounting state. In other words, after the door 16 is closed, the holder drive arm 31 first rotates. The first tape cassette holder 30 begins to move away from the cassette insertion slot 14, reaches a position where the adapter-related members do not interfere with each other when viewed from the top (hereinafter referred to as the holder standby position), and stops. do.

Next, the upper adapter 32 including the second cassette holder 33 begins to rise by the upper adapter lifting mechanism 37, and in conjunction with this, the lower adapter 34 also begins to rise by the movement of the lower adapter lifting mechanism 35. The upper adapter 32 reaches a height corresponding to the cassette insertion opening 14, and the lower adapter 34 stops when it reaches a height that does not interfere with insertion of the second tape cassette 12. This completes the switching operation in the tape cassette mounting device 15 from the state in which the first tape cassette 11 can be mounted to the state in which the second tape cassette 12 can be mounted. After this state is reached, 1s16 is automatically opened and the state shown in FIG. 5 is achieved.

FIG. 5 shows the state when the second tape cassette 12 is installed. When the second tape cassette 12 is inserted into the second tape cassette holder 33 and reaches a predetermined position, the lower adapter 34 automatically moves up by the remaining stroke to combine with the upper adapter 32. At this time, the external dimensions of the combined product formed by the upper and lower adapters 32 and 34 and the second cassette holder 33 including the second tape cassette 12 are as follows: The shape is very similar to the first tape cassette 11 except for a part. Therefore, after the upper and lower adapters 32 and 34 have been assembled, the first cassette holder 30 begins to move toward the cassette insertion port 14 from the holder standby position described above.

When it enters in a manner that wraps around the combined object and reaches a predetermined position, both are automatically held. After that, the first cassette holder 30 is now moved in the opposite direction to the cassette insertion slot 1.
4, and is transported to the position indicated by the broken line in FIG. 5, that is, to a predetermined position on the mechanical chassis 36. Note that during this conveyance, while the first cassette holder 30 is moving horizontally, the second tape cassette 12
is in the combined object, and the tape loading operation is automatically performed by the vertical adapter drive mechanism, so that the tape cassette 11 is ready to be mounted on the mechanical chassis 36 in the same way as the first tape cassette 11. It has become.

Next, after using the second tape cassette 12, the first tape cassette 12 is used again.
The case of using the tape cassette 11 will be explained. When the eject button is operated to take out the second tape cassette 12, the tape cassette mounting device 15 performs an operation completely opposite to that described above, and the second tape cassette 12 comes out through the tape insertion slot 14. At this time, even if the door cassette 6 is not opened originally, it is controlled to open in advance with a certain time difference before the second tape cassette 12 comes out. The state immediately after the second tape cassette 12 comes out is basically the same as the state shown by the solid line in FIG. If you give it, slG will always be in the closed state like last time. Thereafter, as shown in FIG. 6, first, the upper and lower adapters 33, 34, which are adapter-related members including the second cassette holder 33, are lowered to a predetermined position by the respective elevating mechanisms 37, 35 and stopped. From this state, the first cassette holder 30 begins to move from the holder standby position toward the cassette insertion port 14, reaches a predetermined position in the upper space of the adapter-related member, and stops. When this operation is completed, the door 16 is automatically opened and the first tape cassette 11 can be inserted. This state is exactly the same as the state shown in FIG.

Thereafter, two types of tape cassettes having different shapes can be directly attached and detached in the same manner.

(Effects of the Invention) As described above, according to the present invention, two types of irregularly shaped tape cassettes can be selected and directly attached to each other, and the door is opened and closed by electromagnetic drive. It can be opened and closed by remote control. Furthermore, the door is closed during the switching operation to enable the attachment of two types of irregularly shaped tape cassettes to the tape cassette loading device, and is opened after the switching operation is completed. Safety can be ensured by preventing accidents such as fingers getting caught or foreign objects being mixed in. Furthermore, the door can be closed in conjunction with the tape cassette ejection operation, so that it can be easily opened and closed during normal operations such as recording and playback.
