When the door 34 is closed, the pusher 34e aligns the cassettes, and when the closing is completed, the detection switch 36 is operated and the closing of the door 34 is detected.

Therefore, if the door 34 is not closed due to incomplete insertion of the cassette, etc., the detection switch 36 will not operate.

Next, from among the cassettes loaded in the manner described above, an instruction is given as to which one to select and reproduce using the operation button 33.

Then, as shown in FIG. 38, it is detected whether a cassette load instruction or a cassette return instruction has been received, and if this instruction is received, the detection switch 36 detects whether the door 34 is closed and the door is closed. Loading unit 19 operates only when 34 is closed.

Before the loading arm 17 starts operating due to the operation of the loading unit 19, the engaging portion 27s of the catcher 27, the stopper rubber 2
The pin 7k of the lock lever 7a and the guide pin 6a of the holder 6 are at different positions in the front-rear direction, and this state is shown in FIGS. 17 and 18.

When the loading unit 19 rotates in this state, the gear 19h drives the loading gear 17a, and the biasing force of the spring 17f causes the notch 17c to rotate.
The loading plate 17b is rotated while the protrusion 17d is kept in contact with the protrusion 17d.

Due to this rotation of the loading plate 17b, the catcher 27, whose shaft 27a is inserted into the guide hole 17e, is rotated by the loading plate 17b.
It rises to a height corresponding to the rotation angle.

The rotation angle of the loading arm 17 is detected by the rotary encoder 20, and when the catcher 27 reaches the height of the holder 6 at the desired position, the loading unit 19 stops rotating.

When the catcher 27 stops in this way, the drive unit 11 rotates, and the drive gear 11b and the rack 2
2, the mechanical base 5 to which the drive unit 11 is attached starts to move rearward.

The shaft 27a of the catcher 27 is inserted through the guide holes 2a, 3a of the side plates 2, 3 fixed to the mechanical base 5 and the guide hole 4a of the slide plate 4, so the catcher 27 moves rearward together with the mechanical base 5. .

As a result of this movement, the roller 2 of the lock lever 27l of the catcher 27 first moves as shown in FIG.
7p comes into contact with the cam surface 7f of the panel side plate 7, the lock lever 27l is pushed up, and the lock lever 27l is pushed up.
The locking of the sub catcher 27f by the shaft 27n of the shaft 7l is released.

When this lock is released, the catcher 27
Due to this movement, the engaging portion 27s is fitted into the guide pin 6a.

Then, as the lock is released, the sub catcher 27f is pulled by the spring 27e and moves as shown in FIG.
Securely maintain the fit of a.

In this way, the engaging portion 27s and the stopper rubber 27
At the same time as the holding of the guide pin 6a by the stopper part 7g is completed, the cam part 27t comes into contact with the pin 7e of the lock lever 7a and pushes it down, as shown in FIG. 6 can be moved backwards.

With the holder 6 moving backward together with the catcher 27 and the guide pin 6a completely removed from the guide groove 7c, the mechanical base 5 operates the detection switch 23, stops the drive unit 11, and moves the mechanical base 5. make it stop.

At the same time as the stop, loading unit 19
starts rotating, and the loading arm 17 is rotated in the same direction again.

Therefore, the guide pin 6a inserted into the guide hole 17e of the loading arm 17 rises along the vertical portions of the guide holes 2a, 3a of the side plates 2, 3 and the guide hole 4a of the slide plate 4,
That is, the holder 6 also rises together with the catcher 27.

However, when the upper ends of the vertical parts of the guide holes 2a and 3a are reached, the catcher 27 and the holder 6 are moved rearward while moving the slide plate 4 backward along the horizontal parts of the guide holes 2a and 3a, and the holder 6 is The held cassette is moved above the mechanical unit 29.

Furthermore, when the guide pin 6a reaches the short vertical part of the guide holes 2a and 3a, it lowers the catcher 27 and the holder 6 by lowering the guide hole 4a, opens the cassette lid, and sets the cassette in the travel drive mechanism. And then loading gear 1
7a continues to rotate, and the loading plate 17b resists the bias of the spring 17f.
After changing the position with respect to 7a and pushing down the cassette by the force of the spring 17f to ensure that it is set in the traveling drive mechanism, the loading unit 19 stops and the tape can be played back.

In this way, when the tape is being played, the door 34 can be opened by operating the operation button 33.
You can open it and replace the cassette.

However, at the position of the holder 6 where the cassette is transported and set in the travel drive mechanism, the holder 6 that keeps the blocking plate 28 in the raised position is moving as shown in the fourth row of FIG. Plate 28 is now in a sagging position, making insertion of the cassette in this position impossible.

When the operation button 33 is pressed after the tape has been played back as described above or at any time, the tape is wound into the cassette.

After the winding is completed, loading unit 1
9 rotates in the opposite direction, drives the loading arm 17 in the opposite direction, moves the catcher 27 up and down and forward along the guide holes 2a and 3a, and also moves the slide plate 4 forward.

At this time, the detection switch 7b for the holder 6 that has been carried out is OFF, and the other detection switches 7b are ON, so the position of the guide groove 4c of the holder 6 that is being carried out is detected, and the position of the holder 6 is detected. When the catcher 27 is lowered to this point, the loading unit 19 stops.

The state shown in FIG. 32 or 33 in which the stopping position of the loading arm 17 due to this blocking is deviated either above or below the position shown in FIG. 31 where the guide pin 6a and the guide groove 7c face each other. In preparation for this case, the entrance of the guide groove 7c is made into an enlarged tapered shape.

In the case of FIG. 32, since the guide pin 6a hits the upper taper, it is pushed by this and rotates the loading arm 17.
7 pushes down the worm 19c against the spring 19f within the range of the restriction ring 19g.

Conversely, in the case of FIG. 33, the guide pin 6a is pushed up by the taper, and the worm 19c
push upward.

In this way, the guide pin 6a will be introduced into the guide groove 7c, but this will cause the drive unit 1
1 pushes the mechanical base 5 forward,
This is done when the catcher 27 and holder 6 are returned forward together with the slide plate 4 and side plates 2 and 3.

When the catcher 27 moves forward, as shown in FIG. 26, the guide pin 6a first pushes down the lock lever 7a, allowing it to move to the stopper portion 7g.

Next, as shown in FIG. 27, the guide pin 6a advances to the end of the guide groove 7c, and further movement becomes impossible, but the catcher 27 continues to move forward, and the engaging portion 27s is inserted into the guide pin 6a. deviate from

At this time, the guide pin 6a is locked by the stopper portion 7g of the lock lever 7a.

After that, the catcher 27 continues to move forward, but as shown in FIG.
The stopper rubber 27k is prevented from advancing by the guide pin 6a.

At this time, the roller 27p has passed the cam surface 7f, so when the stopper portion 27g finishes passing, it falls onto this and the roller 27n is moved to the sub catcher 27f.
is in a locked state.

At the same time, the detection switch 24 operates, and the drive unit 11 rotates in the opposite direction again to move the catcher 27 backward to the position shown in FIG. 17, and then the drive unit 11 stops.

In order to perform such an operation, it is preferable to use a switching switch as the detection switch 24.

In FIG. 39, which is the state shown in FIG. 17, the terminals a, b, and c of the detection switch 24 are
In FIG. 40, which is the state shown in FIG. 28, the state shown in FIG.
In the figure, the connection between b and c is turned on.

When the detection switch 24 is in the state shown in FIG. 39, the catcher 27 is moved up and down, but the sub catcher 27f must be locked.

However, while moving in the eject direction, the power
If the subcatcher 27f is turned OFF and happens to stop at the position shown in FIG. 39, the subcatcher 27f is not yet locked.

However, in order to lock the subcatcher 27f the next time the power is turned on, the program shown in FIG. 43 can be created.

This program issues operation commands to the drive unit 11 according to the current state based on the ON state of the detection switch 24 and the ON/OFF state of the detection switch 23.

After the holder 6 is separated from the catcher 27 in the manner described above, the loading unit 19 rotates again to lower the catcher 27 to its lowest position, completing the cassette ejecting action.

When the cassette is replaced and playback is performed, the above-described operations are repeated.

Next, another embodiment will be described below with reference to FIGS. 44 to 52.

This embodiment differs from the previous embodiment only in the catcher 27 and panel side plate 7, and all other parts are the same as in the previous embodiment, so only this different part will be explained, and the other parts will not be explained. Omitted.

In this embodiment, a gear 51 meshes with a worm 50b of a drive unit 50 having a motor 50a, an arm 52 connects the gear 51 and the mechanical base 5, and an arm 52 that rotates together with the gear 51 and operates two detection switches 53 and 54. Cam 55 to operate
It consists of

As shown in FIGS. 54, 55, and 58, when the guide pin 6a is in the position shown in FIG. 55, the detection switch 53 is OFF and the detection switch 54 is ON.

Then, the catchers 27 and 40 are moved to remove the holder 6 holding the cassette from the guide groove 4c.
When operating, the drive unit 50 is driven to rotate the gear 52 and cam 55 in the direction of arrow A in FIG.

Then, as shown in FIG. 59, the mechanical base 5 is pulled by the arm 52 and starts to move backward as shown by arrow B. At this time, the detection switch 53 is turned on and the gear 5 is turned on.
1 indicates that it is in operation, but the detection switch 5
4 is OFF.

When the retreat of the mechanical base 5 is completed, the detection switch 54 is turned on, as shown in FIG.
3 remains ON.

Next, during the eject operation to return the holder 6 to the guide groove 7c, the gear 51 is rotated by the drive unit 50 in the same direction as the beginning, that is, in the direction of arrow A, as shown in FIG. Move it in the direction of arrow B.

At this time, as shown in FIG.
continues to be ON, but the detection switch 53 shifts to the OFF state.

Then, the state shown in FIG. 58 is reached via the state shown in FIG.
operation is completed.

At this time, the detection switch 54 is in the OFF state, thereby stopping the drive unit 50, but the detection switch 53 is in the OFF state.

In this way, in this embodiment, the detection switch 5
The drive unit 50 is controlled by turning ON and OFF 4, but if the power is turned off while the drive unit 50 is rotating.
When turned off, both detection switches 53 and 54
The ON/OFF state of the mechanical base 5 determines the position and direction of movement of the mechanical base 5, and determines the operation when the power is turned on again.

In this embodiment, efficiency can be achieved at intermediate positions where a high moving speed is required, and at initial and final positions where a pressing force is required.

[Effect of idea]

As described above, in the present invention, before the tape cassette inserted into the holder from the insertion opening is conveyed by the loading means toward the tape traveling mechanism, the door is slid to close the insertion opening, and the tape cassette during loading is closed. To prevent insertion errors.

As the door closes and slides, the door pusher slides against the front side of the tape cassette under its bias and pushes the tape cassette toward the holder, so that the tape that is incompletely inserted can be removed. The cassette is pushed into position and accurately aligned.

Therefore, when the tape cassette is transported toward the tape transport mechanism, it is reliably held in the correct position of the loading means, and the tape cassette does not fall off from the loading means during transport, or the tape cassette hits a component on the way, and the tape This can prevent damage to the cassette or malfunction of the player.
