FIG. 9 is a plan view showing a procedure for mounting the cassette 5 to the magazine 32. The user first starts the magazine from the device body 31.
Then, the first cassette 5 is inserted from the notch 42 in the direction of the arrow in FIG. 9 along the cassette holder 39 to the position of the stopper 40. Next, by turning the turntable 34, another cassette holder 39 is brought to the position of the cutout 42, another cassette 5 is inserted in the same manner as the first cassette 5, and finally the cassette 5 is returned to the state shown in FIG. Are mounted.

When the loading of the cassette 5 is completed, the user can read the magazine 32
2 in the direction of the arrow in FIG.
When the switch 62 is pressed by the protrusion 44 and turned ON, the mounting of the magazine 32 is completed.

Next, the user selects the cassette 5 to be recorded or reproduced and the deck 3 to be used by means not shown. In the present embodiment, only the case where each of the cassette 5a and the deck 3a is selected is shown, but the same applies to the case where other cassettes and decks are selected, so that the description is omitted for simplicity.

FIG. 10 is a plan view showing a state where the cassette 5a to be played is not yet selected after the magazine 32 is mounted. The idler portion 50 of the rotor 52 is pushed by the upper portion of the outer peripheral surface of the turntable 34, and the lever 48 rotates clockwise against the spring 53 and leaves the stopper 54. The idler 50 acts as a pressing force on the outer peripheral surface of the turntable 34.

It is in the state of. The deck 3a is lowered to a position where the reel rest 29 does not interfere with the magazine 32, and the deck 3a is stationary with the switch 75 turned on.

FIG. 11 is a plan view showing a state in which the cassette 5a to be played is selected.After the cassette and deck selection operation by the user, the motor 45 rotates and the gear 47, the rotor 5
The turntable 34 is rotated via 2. Then, the roller 57 of the position detecting lever 55 is engaged with the concave portion 43 of the turntable 34 and the switch 58 is turned on. At this time, if the photoelectric switch 61 for the cassette 5 to be played is turned on, the motor 45 stops and is turned off. If there is, the motor 45 rotates further, and the next recess 43
A similar determination is made.

In this way, when the cassette 5a selected by the above selection operation is set on the deck 3a to be used, the motor 63 rotates and the lever 66 moves upward to push up the deck 3. Then, when the reference pin 78 comes into contact with the cassette 5, the presser 71 stops, but the lever 66 still moves upward, so that the deck 3a is pressed against the cassette 5a by the compression spring 73, and the switch 74 is turned on. At this point, the motor 63 stops, and the performance becomes possible.

When the user next selects another cassette 5a, first, the motor 63 rotates, the lever 66 moves downward, and the deck 3a
Is lowered to a position where the reel rest 28 does not interfere with the magazine 32. Then, when the switch 75 is turned on, the motor 63 stops, and then the motor 45 rotates to select the next cassette 5a.

In the above embodiment, an example in which an arbitrary tape cassette is mounted on an arbitrary deck to perform recording / reproduction has been described. However, when duplicating / editing a signal between a plurality of tape cassettes, the user can reproduce the signal by means not shown. The deck 3a and the recording deck 3b and the reproducing cassette 5a and the recording cassette 5b are selected.

Then, by the same operation as described above, the playback cassette 5a is placed on the playback deck 3a, and the recording cassette 5b is placed on the recording deck 3b.
Is set. Then, the user operates the operation buttons (not shown) or the like to start the reproduction operation of the deck 3a and the recording operation of the deck 3b, and copy / edit a signal between the cassettes 5a and 5b.

In the above embodiment, only the duplication and editing of signals by a plurality of decks has been described. However, a configuration may be adopted in which simultaneous reproduction or simultaneous recording is possible.

In the above embodiment, two decks 3a and 3b are arranged 180 ° opposite to each other. However, the decks 3a and 3b may be configured to be movable in a plane parallel to the turntable 34. It is even better to arrange the decks for the number of cassettes 5.

Further, in the above embodiment, the vertical drive mechanism 36 for vertically driving the deck 3 is shown as the deck drive mechanism for mounting the selected cassette 5 on the deck 3, but the deck 3 is supported as shown in FIG. A mechanism that swings around the shaft 79 to move up and down may be used.

In the above embodiment, the case where the cassette 5 is selected by the operation keys has been described. However, a memory circuit and a system control circuit are provided for mounting, and when the user inputs the playing order, the data is stored in the memory circuit and the system control circuit is stored. , The cassette 5 may be automatically selected, and the performance may be performed continuously.

Furthermore, in the above embodiment, the rotation of the turntable 34 was performed by pressing the outer peripheral surface against the idler portion 50 of the elastic body, but the upper portion of the outer peripheral surface of the turntable 34 and the outer peripheral surface of the idler portion 50 were geared. It may be formed so that the turntable 34 is rotated by meshing of gears.

Further, in the above embodiment, the photoelectric switch 61 is connected to the one of the identification holes 41.
Although the case where one is provided for each is shown, when the number of the photoelectric switches 61 is n, an identification signal of n bits, that is, 2 ⁿ patterns is obtained, and the identification hole 41 is formed as a pattern using this. The same effect may be obtained.

The cassette 5 may be an analog or digital music tape, a video tape such as VHS, β, 8 mm VTR, or a tape cassette of another standard.

〔The invention's effect〕

As described above, according to the present invention, since a plurality of decks capable of recording and reproduction are provided, signals can be duplicated / edited between a plurality of cassettes, and a mechanism for driving the cassettes until they can be played. A mechanism for rotationally driving the other in the magazine in which the cassette is inserted for selection of the cassette,
Because it is configured with a mechanism with one degree of freedom, with a mechanism that drives the deck up and down for mounting the cassette on the deck,
The driving mechanism is simple, the number of parts can be reduced, and the moving space for the deck and the cassette can be reduced to achieve the effect of downsizing.
