Description

[Detailed Description of the Invention] This invention relates to a recording/playback device that records or plays back when a card having a magnetic recording band is passed through a guide groove.

A recording/playback device includes a pair of pinch rollers and a head arranged opposite to each other in a guide groove, arranged vertically in parallel, and when a card provided with a magnetic recording band is passed through the guide groove, the head records or reproduces the card. For example, this technique is known from Japanese Utility Model Publication No. 119505/1983, which was proposed by the present applicant.

However, in the conventional recording and reproducing apparatus described above, the only difference is the vertical position of the left and right heads, and the switch mechanism is not specifically shown.
If a switch mechanism is provided, a switch for starting drive and a switch for stopping drive must be provided close to each head. However, 2
If separate switches are provided, each switch must be wired individually and the mounting position of each switch must be determined accurately.

The present invention has been proposed in view of the above, and uses a card that passes through a guide groove to allow a single switch to be used for both starting and stopping the drive.

The present invention will be described below with reference to the embodiments shown in the drawings. Reference numeral 1 denotes a frame with a horizontal partition plate 2 provided therein, and a guide groove 3 formed in the width direction of the frame 1 located above the partition plate 2. . On the upper surface of the partition plate 2, a first recording/reproducing head 4 and a first pinch roller 5, and a second recording/reproducing head 6 and a second pinch roller 7 are arranged side by side on the left and right with the guide groove 3 in between.

The above-mentioned first head 4 and second head 6 have different vertical positions, and in the embodiment shown in the drawings, the second head 6 is higher than the first head 4 by the height of the head. A magnetic recording band b equal to the height of the first head 4 and the second head 6 is provided in the horizontal direction on the card a to be passed through the guide groove 3, and the width of the card a is equal to the height of the first head 4 and the second head 6. 6.

Insert this card a from one end of the guide groove 3,
When the card is moved within the card slot 3, the first head 4 comes into contact with the lower part of the magnetic recording band b to perform recording or reproduction. Then, the card a gradually moves, and at the same time the magnetic recording band b leaves the first head 4, the second head 6 comes into contact with it, and the second head 6 moves into the magnetic recording band b.
Play or record the first half of .

Therefore, since both heads 4 and 6 individually record or reproduce the upper or lower part of magnetic recording band b,
Overall, it is possible to record or reproduce twice the length of the magnetic recording band b.

In the recording and reproducing apparatus described above, the gist of the present invention lies in the switch mechanism when the card a is passed through the guide groove 3. This switch mechanism has a switch mechanism 11 that faces one of a first operating rod 9 and a second operating rod 10, which are pivoted in the middle of their lengths to bearings 8, 8 provided upright on the partition plate 2. It is shown as.

One end of the first operating rod 9 has a first contact portion 12 facing near the first head 4 of the guide groove 3, and a second contact portion 12 facing near the first head 4 of the guide groove 3.
A second head 6 of the guide groove 3 is provided at one end of the operating rod 10.
It has a second contact portion 13 facing near.

The other ends of the first actuating rod 9 and the second actuating rod 10 are pivotally connected to each other by a long hole 14 and a pin 15, and the contact pieces 16, 17 of the switch mechanism 11 are connected to the second actuating rod 1.
Make elastic contact in the middle of 0.

In the drawing, 18 is a recording operation section, 19 is a microphone, and 20 is a speaker.

The first operating rod 9 and the second operating rod 10 are connected by a long hole 14 and a pin 15, and each can rotate about the bearings 8, 8 as a fulcrum. When the card a is not passed through the guide groove 3, the first
As shown by the dotted line in the figure, the first contact part 12 crosses and closes the guide groove 3 above the first head 4, and the second contact part 13 covers the guide groove 3 above the second head 6. It crosses and blocks. In this state, the contact pieces 16 and 17 of the switch mechanism 11 are not in contact, so the switch mechanism 11 is OFF.
However, when the card a is manually passed through one end of the guide groove 3, the tip of the card a presses the first contact part 12, so the first operating rod 9 is moved to the pivot point, that is, the bearing part 8,
8 as a fulcrum, and the first contact portion 12 is removed from the guide groove 3. Along with this rotation of the first operating rod 9, the second operating rod 10 also rotates so that the second contact portion 13 is removed from the guide groove 3, and as a result, the contact piece 1
6 and 17 come into contact and the switch mechanism 11 is turned on. Therefore, the first pinch roller 5 and the second pinch roller 7 rotate, and a power supply mechanism (not shown) provided in the frame is activated, so that the card a moves within the guide groove 3. Become. Since the first head 4 contacts the magnetic recording band b of the card a, it can be reproduced by the speaker 20,
Alternatively, recording can be made by pressing the recording operation section 18. Also, just before the card a leaves the first head 4 and the second pinch roller 5, the leading edge of the card a is
It passes between the head 6 and the second pinch roller 7. Therefore, the second contact portion 13
Since the second operating rod 10 and the first operating rod 9 do not rotate back, the second head 6 contacts the magnetic recording band b of the card a to record or play back. do.

When the card a moves further and its rear end passes between the second head 6 and the second pinch roller 7, the second contact portion 13 comes off the card a, and the second operating rod 1
0 is rotated back together with the first operating rod 9 by the urging of the switch mechanism 11, and the first contact portion 12 and the second contact portion 13 close the guide groove 3, respectively.

Therefore, according to the present invention, simply by passing the card a through the guide groove 3, the switch mechanism 11 is turned on by the rotation of the first operating rod 9 and the second operating rod 10, allowing recording and playback.

Further, when the card a passes the second head 6 and the second pinch roller 7, the switch mechanism 11 is activated by the return rotation of the first operating lever 9 and the second operating lever 10.
It becomes OFF. Therefore, not only is the structure and wiring extremely simple, but the switch mechanism is reliably turned ON or OFF just by inserting the card into the guide groove, and there is no possibility of malfunction.

Furthermore, when the card finishes passing between the first head and the first pinch roller, it passes between the second head and the second pinch roller, but at this time, the guide groove is formed so that the second contact part is removed. Since it is open, cards can pass through it without resistance, and the tip will not be damaged or torn. If a postcard is used as a card, the recipient can enjoy playing back what the sender has recorded.
