Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention opens the reel hole by sliding a slider that covers the reel hole of the tape cassette, and covers the tape running surface. Unlock the lid that is open, then open the lid and set the tape cassette for digital audio that is set in the tape running mechanism,
The present invention relates to improvement of a cassette loading device to be loaded on a tape player.

[Conventional technology]

A conventional tape cassette loading device for digital audio is shown in FIG.

In FIG. 1, reference numeral 1 is a holder into which the tape cassette 2 is inserted, and a slider 3 that closes a reel hole on the lower surface of the tape cassette 2 when the tape cassette 2 is inserted hits a hook 4 fixed to the holder 1 to The bottom surface of the tape is slid to open the reel hole, and the lid 5 that covers the tape running surface of the tape cassette 2 is unlocked.

A push switch 6 is attached to a mounting plate 7 at the rear end of the pocket of the holder 1 into which the tape cassette 2 is inserted.

When the insertion is completed and the slider 3 is completely slid, the push switch 6 is operated by the tape cassette 2
The holder 1 is operated by the loading mechanism, and the tape cassette 2 is set in the tape running mechanism.

[Problems to be solved by the device]

In the above cassette mounting device, the push switch 6 must be turned on at the same time when the slider slide is completed.

Therefore, the operating position of the push switch 6 becomes very delicate.

Therefore, a method of adjusting the position of the push switch 6 by providing the mounting plate 7 with the groove 7a and the groove 7b facing each other, inserting the tip of a flat-blade screwdriver into the grooves 7a and 7b, and twisting them Was taken.

However, even if such an adjusting means is provided, it is difficult to adjust the push switch 6 once, and the workability is poor.

Further, if the position changes during use, the loading operation may not be performed smoothly.

[Purpose of device]

The present invention solves the above-mentioned problems of the conventional cassette mounting apparatus for digital audio, and expands the movement of the cassette inserted in the pocket to operate the switch, so that the position where the cassette operates the switch is accurately determined. Therefore, it is an object of the present invention to provide a cassette mounting device that does not require adjustment and that is easy to achieve.

[Outline of device]

The present invention relates to means of a cassette loading device for achieving the above-mentioned object, wherein a rotating member rotated by a tape cassette inserted in a pocket releases the locking of the operating member, and the operating member is urged by the biasing force. The switch is operated to set the cassette in the tape drive mechanism.

[Example of device]

Next, an example of implementation of the present invention will be described with reference to FIGS.

In FIGS. 1 and 2, a is a tape drive mechanism provided in the mechanical chassis b, and a lid opener c is provided on the mechanical chassis b for contacting and opening the lid 5 of the tape cassette 2. An arm 8 of the holder 1 having a pocket for inserting the tape cassette 2 is pivotally supported on the support plate d fixed to the mechanical chassis b so that the holder 1 can be opened and closed.

Then, the holder 1 hits a slider 3 that slides on the lower surface of the tape cassette 2 and slides it on the tape cassette 2 to open the reel hole on the lower surface of the tape cassette 2 and unlock the lid 5. 4 are provided.

In FIG. 3 to FIG. 6, 10 is a pin provided upright on the holder 1, into which the long hole 11a of the operating plate 11 is slidably inserted, and the rotating arm 12 is rotatable. It is pivotally supported.

An L-shaped lock hole 11b provided in the actuating plate 11 is slidably inserted into a pin 13 provided upright in the holder 1, and a spring 14 provided between the actuating plate 11 and the holder 1 causes the actuating plate 11 to have an elongated hole 11a. The lock hole 11b is guided and moved.

However, when the corner portion of the lock hole 11b is locked to the pin 13, the movement of the operating plate 11 is locked.

A pin 12 a that contacts the lid 5 is erected on the rotating arm 12 immediately before the slider 3 of the tape cassette 2 is completely slid by the hook 4.

Further, the operating plate 11 is provided with a protrusion 11c that comes into contact with the pin 12b when the rotating arm 12 rotates while the lock hole 11b is locked by the pin 13.

Further, when the rotating arm 12 is rotated, the operating plate 11 has a protrusion
Pin 11d that hits 12c and is pushed up against spring 14
Are formed.

Reference numeral 15 is a spring for returning the rotating arm 12, and 16 is a push switch installed so as to face the operating plate 11.

Next, the operation of this cassette mounting device will be described.

When the tape cassette 2 is inserted into the pocket of the holder 1 as shown in FIGS. 1 and 2, first, the slider 3 is brought into contact with the hook 4 and the slider 3 is slid.

Immediately before the slide of the slider 3 is completed and the lock of the lid 5 is released, the lid 5 is fixed to the pin of the rotating arm 12.
When the slider 3 comes into contact with the slider 12a and the slide of the slider 3 is completed, the rotating arm 12 is rotated as shown in FIG.

That is, the pin 12b of the rotating arm 12 hits the protrusion 11c of the actuating plate 11 and pushes it, so that the actuating plate 11 rotates about the pin 10 and the locking of the pin 13 with respect to the lock hole 11b is released. It

Therefore, the operating plate 11 is pulled by the spring 14, and the lock hole 11b moves while being guided by the pin 13 and the long hole 11a by the pin 10 as shown in FIG. 5, and pushes the push switch 16 to turn it on.

When turned on, the motor rotates and the holder 1 rotates in the closing direction as shown in FIG. 2 to set the tape cassette 2 in the tape running mechanism a.

At this time, since the lid 5 is opened by the lid opener c, the pin 12a is pushed and the pivot arm 12 is pushed as shown in FIG.
Is further rotated, and the projection 12c hits the pin 11d to push up the operating plate 11 against the spring 14.

At this time, the spring 14 urges the operating plate 11 to rotate counterclockwise about the pin 10, so that the lock hole
11b is locked by the pin 13.

Thus, although the mounting of the tape cassette 2 is completed, when the eject switch (not shown) is operated when the tape cassette 2 is ejected, the holder 1 reversely moves the tape cassette 2 from the tape drive mechanism a. Release and rotate in the opening direction.

At this time, the rotating arm 12 is urged by the spring 15 to move the pin 11a.
Moves in the direction of closing the lid 5 and returns to the state shown in FIG. 3, and the tape cassette 2 is pulled out from the pocket to complete the ejecting operation.

[Effect of device]

As described above, when the insertion of the tape cassette reaches a certain position, the rotating member rotated by the tape cassette unlocks the actuating member, and the actuating member is moved by its biasing force to switch the switch. Can be activated to start the loading operation.

Further, since the rotation of the rotating member can be expanded to unlock the actuating member, the timing of the switch operation can be accurately adjusted to the timing of the completion of the slide of the slider, and thus the adjustment work thereof is unnecessary. You can

Also, since the timing does not change during use,
It is possible to provide a tape cassette mounting device that does not require adjustment work or fear of failure.
