[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the shuttle body 2 is connected to the guide rod 3.
4 so that it can reciprocate. Further, holding plates 5a and 5b are attached to the shuttle body 2 with a gap slightly larger than the thickness of the card 1 so that the card 1 can be inserted and removed.

Further, the card clamper 6 and the unlock hold lever 7 are attached to the shuttle body 2 with a pin 11. They are each rotatably attached by pins 12. The card clamper 6 is provided with clamp fingers 10a and 10b for clamping the card l. The clamp fingers 10a and 10b are made of an elastic material having a large coefficient of friction with the card 1, such as rubber, for the purpose of clamping the card 1.

One end of a spring 8.9, which will be described later, is attached to the card clamper 6 and the unlock hold lever 7 in order to clamp the card 1 and release the clamp.
．． The other ends of each of the shuttle bodies 9 are attached to the shuttle body 2, respectively.

Further, a pawl 13 is formed on the card clamper 6, and a convex portion 14 is formed on the unlock hold lever 7, which engages with the pawl 13 and serves to prevent rotation of the unlock hold lever 7. has been done. Further, the card clamper 6 is provided with a slope cam 15.
As shown in FIG. 4, a release lever 16 that engages with the lever 5 is rotatably attached to the main body of the shaft.

The release lever 16 is biased counterclockwise in FIG. 4 (towards the front of the shuttle body) by a spring 17, and can be rotated clockwise without extending the spring 17.
In the counterclockwise direction, as shown in FIG. 4, the chassis body 19 serves as a stopper and is mounted in such a manner that it cannot move once.

With the above configuration, the operation of the card 1 conveyance/holding mechanism will be described below.

In FIG. 4, FIG. 4(a) shows a state before the card 1 is inserted or in a state where the card 1 can be removed, and the position of the shuttle body 2 in this state is assumed to be 1t'2A. At this time, spring 8
The claw 13 of the card clamper 6, which is biased forward and upward of the shuttle body 2, is pushed away by the lever 9, and the convex portion 14 of the unlock hold lever 7, which is biased forward and downward of the shuttle body 2.
I'm suppressing it. Since the biasing force of the spring 9 is much stronger than the biasing force of the spring 8, the spring 8 is extended and the claw 13 of the card clamper 6 is held down by the convex part of the afro-hold lever 7. . In this suppressed situation,
Clamp finger 1 provided on card clamper 6
The spacing between 0a, 10b and the holding plates 5a, 5b is set larger than the thickness of the card 1, so that the card 1 can be freely inserted and blown out.

First, the insertion operation of the card 1 will be explained. Front panel 30
Insert the card 1 from the card insertion slot 18. At this time, the shuttle main body 2 is prevented from moving by a locking means (not shown). The card 1 comes into contact with the head 7a of the unlock hold lever 7, and when the card 1 is pushed further, the unlock hold lever 7 extends the spring 9 around the pin 12 as shown in FIG. 4(b). Rotate clockwise like this. Then, the convex portion 14 that was holding down the pawl 13 releases the pawl 13, and the card clamper 6 rotates counterclockwise in the figure around the pin 11 due to the biasing force of the spring 8. As a result, the clamp finger 10a provided on the card clamper 6.

10b presses card 1. Therefore, the card 1 includes the holding plates 5a, 5b and the clamp finger 10''*1.
Clamped by 0b.

Note that the claw 13 of the card clamper 6 comes into contact with the protrusion 14 of the unlock hold lever 7, and the unlock hold lever 7 is rotated counterclockwise in the figure by the spring 9.
I try not to.

The clamping of the card 1 is detected by a microswitch (not shown), and the aforementioned locking means is unlocked! A moving motor (not shown) moves the shuttle body 2 to the fourth position.
The card 1 is moved from position A shown in FIG. 4B, in which it is protruding, to position B, shown in FIG. 4C, in which the card 1 is completely inserted into the device from the card insertion slot 18. At this time.

The slope cam 15 provided on the card clamper 6 and engaged with the release lever 16 rotates the release lever 16 counterclockwise in the figure while extending the spring 17 and passes.

The shuttle main body 2 has moved to position B in this way.

As shown in FIG. 4(d), in order to perform recording or reproduction on the card 1, it is supported by a guide rod 3.4 and reciprocated between position 1 B and position CQ by a driving means (not shown).

Next, the operation of taking out the card 1 after recording or reproduction on the card 1 is completed will be described. When recording or reproduction on the card 1 is completed, the shuttle body 2 stops at position B. After that, the shuttle body 2 is moved by a drive motor (not shown).
It moves from the state shown in FIG. 4(C) to the state shown in FIG. 4(b), that is, from position B to position A.

During this movement, the slope cam 15 provided on the card clamper 6 comes into contact with the release lever 16, but the release lever 16 is prevented from moving counterclockwise in the figure by the chassis body 19. The slope cam 15 is pushed up by the release lever 16, and the card clamper 6 rotates clockwise in the figure while extending the spring 8. At this time, the claw 13 of the card clamper 6, which was in contact with the protrusion 14 of the afro-lock hold lever 7 and prevented the rotation of the unlock hold lever 7, is moved to the protrusion 14.
Claw 13 that rotates downward and prevents one rotation.
As a result, the unlock hold lever 7 rotates counterclockwise in the figure, and the protrusion 14 holds down the pawl 13 as shown in FIG. 4 (pl).

Therefore, the pressure of the clamp fingers 10a, 10b that was pressing the card 1 is released, the card 1 can be taken out, and the card 1 is pushed out by the rotation of the unlock hold lever 7.

In this way, by inserting the card 1 from the card insertion slot 18, the card 1 is automatically clamped to the shuttle body 2, and when recording or playback ends, the shuttle body returns to its initial position and the card 1 is automatically clamped to the shuttle body 2. The clamp on card 1 is released and card 1 is pushed out.

Further, as shown in FIG. 4, the shuttle body 2 moves between positions A and B when loading/unloading the card 1, and moves between positions B and C when recording or playing back on the card 1. I try to do 1iii3 legs so that it moves. This is because when recording or reproducing using the card 1, the card 1 must be continuously moved back and forth in a straight line at a certain speed, and the card 1 protrudes from the card insertion slot 18 with each reciprocation. This is because if the card 1 is touched by mistake, it may interfere with recording or reproduction. Therefore, during playback, card 1 is made to completely fall within the % position.

In this way, just by inserting card 1, you can insert card 1.
It is possible to securely clamp the recording and reproducing elements without causing positional deviation during recording and reproducing, and to perform excellent recording and reproducing without being affected by external influences.

[Example of the invention] Another embodiment of the invention is shown in FIGS. 5 and 6.

The card 1 is slightly warped or twisted, which may cause problems during recording or reproduction. Therefore, in order to accurately clamp the card 1 to the shuttle body 2, card holding springs 20a and 20b are provided on the shuttle body 2.

As shown in FIG. 5, a card holding spring 20a.

20b is a boss 22a protruding from the shuttle body 2
.

22b with screws or the like, and is biased to hold down the card 1.

Further, card holding springs 20a are provided on both left and right sides of the card insertion slot 18 of the front panel 30, as shown in FIG.
, canceller 218.21 that cancels the action of 20b.
b is provided.

With this configuration, before inserting the card 1 and when the card 1 can be removed, the tip of the shuttle body 2 is at position A as shown in FIG. The tip that suppresses the movement is pushed down by cancellers 21a and 21b,
Insertion and ejection of the card 1 is performed smoothly.

When card 1 is inserted, s 4th Y (') to 4th
An operation similar to that shown in FIG. 3(b) is performed. (Description will be omitted here) Then, as shown in FIG. 5(b), the shuttle main body 2 is moved to position flu B by a drive motor (not shown).

At this time, the tips of the card holding springs 20a, 20b separate from the cancellers 21a, 21b and press the card 1. As a result, the card 1 is clamped at four locations by the retainers 5a and 5b, the card retainers 20a and 20b, and the clamp fingers 10a and 10b, so that the flatness of the card is maintained well and during recording and playback. Further, FIGS. 7 and 8 show a configuration in which a sensor for detecting that the card 1 is clamped, such as a microswitch 40, is provided. The same reference numerals are given to the same or corresponding parts as in FIG. 4, and the explanation thereof will be omitted.

FIG. 8(a) shows a state before the card 1 is inserted or when the card 1'EQ can be taken out, and the claw 13 of the card clamper 6 is held down by the convex part 14 of the unloader hold lever 7. Therefore, the inclined cam 15 provided on the card clamper 6 does not push the actuator 41 of the microswitch 40.

When the card 1 is inserted as shown in FIG. 8(b), the card clamper 6 rotates around the pin 11, as described above.

As a result, the card 1 is clamped by the clamp fingers 10a and 10b, but at the same time, the apex portion of the inclined cam 15 pushes the actuator 41 of the microswitch 40, and the drive motor (not shown) is activated, causing the shuttle body 28 to ) to the extent shown in dB.

〔Effect of the invention〕

As described in detail above, according to the present invention, the operator
The card can be reliably clamped by simply inserting the card into the arrangement and playback device, and since the card does not shift in position during recording or playback, good recording and playback can be performed.
