Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording and reproducing apparatus for magnetic recording cards and magnetic recording tapes, and more particularly to a magnetic recording and reproducing apparatus suitable for repeatedly reproducing recorded contents of magnetic recording cards and tapes.

FIG. 1 shows the configuration of a general magnetic card.

As shown in FIG. 1, a magnetic card 1 has a magnetic material 3 provided on the entire surface or strip-like shape of a paper or plastic card substrate 2, on which audio, digital information, etc. are recorded. A general reproducing mechanism for reproducing such a magnetic card is shown in FIG. That is, there is a reproducing head 6 which faces the magnetic card feed roll 4 and is pressed by a spring 5.
The magnetic card is inserted between the feed roll 4 and the reproducing head 6 in the direction of the arrow with the magnetic surface in contact with the reproducing head 6, and the magnetic card is run to perform reproduction. The feed roll 4 is driven at a constant speed by a motor or the like, but is not shown in the figure. Now, to explain the case where a magnetic card is used for language learning, the user inserts the card into the playback mechanism while looking at the characters, explanatory text, pictures, etc. printed on the magnetic card, and records are recorded on the magnetic body 3. By listening to the content, language learning is done by using the visual and auditory senses at the same time.
Although magnetic cards cannot record and play back audio for long periods of time, they can be accessed randomly, and text and explanations can be printed on each card, allowing the same card to be used over and over again. It has features such as being able to listen, making it ideal for pronunciation of foreign language words, conversation practice, etc. Now, in the method of playing magnetic cards using the above-mentioned playback mechanism, since the card is running when the card is played, it is inconvenient to see the contents printed on the card, and the same card has to be played repeatedly. In some cases, the card has to be replaced many times, which has the disadvantage that the card is easily damaged. Therefore, an apparatus has been devised in which the recorded contents of a magnetic card are transferred to another endless recording medium and the recorded contents of the card are continuously and repeatedly reproduced from the endless recording medium. (Jitsugan 51-170883
All of these devices use the recording and playback mechanism of a cassette recorder to re-record the recorded contents of the card onto a single loop of endless tape, and from this single loop tape. The advantage of this method is that by simply inserting the card into the machine once, the contents can be played continuously and repeatedly while the card is at hand, and the advantage of this method is that it is possible to play the contents continuously and repeatedly while the card is in hand. Instead, you can simply replace a regular cassette tape and play back much longer content than a card. However, all of these methods use a cassette tape recording and playback mechanism, which is relatively expensive, and the operation of starting the device, which involves loading a cassette and pressing the play button, is cumbersome.
When playing back a cassette tape, it has several disadvantages, such as the fact that if you want to play the tape from beginning to end and want to listen to it again, you have to rewind the tape and play it again from the beginning. In view of the above-mentioned shortcomings of the prior art, it is an object of the present invention to simplify the starting operation with an inexpensive device configuration, and to enable continuous and repeated reproduction of the recorded contents of a magnetic card in one playback. It is possible to provide a magnetic recording/reproducing device that can reproduce the recorded contents of a card only once. According to the present invention, power is supplied to the device by inserting a magnetic card or a back containing an endless recording medium, and when only the magnetic card is inserted, the recorded contents of the magnetic card are directly reproduced. The above-mentioned object is achieved by configuring the apparatus such that repeated playback is performed through an endless recording medium when the recording medium is inserted.

Furthermore, according to the present invention, by inserting another back containing an endless recording medium with a longer period, recorded contents that are much longer than those of a magnetic card can be repeatedly reproduced without the need for rewinding. The sixth order that can also be done is
The present invention will be described in more detail with reference to embodiments of the present invention.

FIG. 3 shows a state in which the recorded contents of a magnetic card are re-recorded on a single loop tape in an apparatus according to an embodiment of the present invention, and the contents are continuously and repeatedly reproduced from the single loop tape, and the electric circuit block at this time is shown. A diagram is shown in FIG.

FIG. 5 shows the playing state of the card, and FIG. 6 shows an electric circuit block diagram at this time. Further, FIG. 7 shows a state in which an endless tape is being played back by this apparatus, and FIG. 8 shows an electric circuit block diagram at this time. First, in FIG. 3, the drive roll 4'' is rotated at a constant speed in the direction of arrow A by a motor or the like (not shown).

The card reproducing head 6 is pressed in the direction of arrow B by a spring 5. The switch 9 opens and closes when a card is inserted, and when the card 1 is inserted between the roll C and the head 6 with the magnetic surface 3 facing the head 6, the card is inserted into the roll 4.
'', the signal recorded on the card 1 is played back by the head 6. On the other hand, the 1-loop tape 12 is stored in a bag 16 made of plastic or the like, and the 1-loop tape guide 14 and pinch roller 13
The recording head 7 with erasing function and the reproducing head 8 are provided so as to be in contact with the magnetic surface of the one-loop tape 12. There is also a switch 11 that is opened and closed by the protrusion 10 of the bag 16, and an interlocking switch 18 that is activated when the bag 16 is inserted.
a, 18b, and 18c are provided as shown in the figure. The bag 16 can be slid on and off in the direction of arrow C along the back guide 15. When the bag is attached as shown in the figure, the 1-loop tape 12 is pressed by the drive roll 4'' and the pinch roller 13 and runs in the direction of arrow D, and the symbol recorded by the erasing recording head 7 is the 1-loop tape playback head. 8.The operation of repeatedly playing back the recorded contents of the card will be explained using Figure 4.First, the 1 loop tape back 16
When attached to the device, the interlocking switches 18a, 18b, 18
In both cases, contact C1 and contact C3 contact each other, and switch 1
Electricity is supplied from the power supply 25 to the card playback amplifier 19, the 1-loop tape playback amplifier 22, the main amplifier 23, and the motor 26 from 8c to rotate the 1-loop tape, and at the same time, each amplifier becomes operational. At this time, the switch 11 is in the ON state at the convex portion 10 of the back 16, but when the card 1 is not inserted, the switch 9 is set to 0F.
Since it is in the F state, electricity is not supplied to the recording amplifier 20 and the erasure/bias circuit 21, so they are not in an operating state. Next, when card 1 is inserted into the device, switch 9 is set to 0N by card 1, and contact C1 between switch 9 and switch 18b is connected to recording amplifier 20, erasure, and bias circuit 21.
- Electricity is supplied by C3 and switch 11, and the signal becomes operational, and the signal recorded on the 1-loop tape is erased by erasing head 7'', and then the signal recorded on card 1 is reproduced by card reproducing head 6. The signal is amplified by the playback amplifier 19, guided to the recording amplifier 20, and re-recorded on the one-loop tape 12 by the recording head 7'' together with the bias signal. The signal recorded on the 1-loop tape is reproduced by the 1-loop tape reproduction amplifier 8, amplified by the reproduction amplifier 22, and then sent to the switch 18.
The signal is led to the main amplifier through contacts C3-C1 of a, and is reproduced from the speaker 24 through the main amplifier 23.
When the playback of the card 1 is finished and the end of the card leaves the switch 9, the switch 9 becomes 0FF, the recording circuit 20 and the erasing bias circuit 21 stop working, and the signal recorded on the 1-loop tape is continuously repeated by the playback head 8. will be played. Next, we will explain the operating state when there is no need to play the card repeatedly, that is, when the card is played only once, using Figures 5 and 6. First, in Figure 5, the bag is not attached to the device. switch 18 because it is not
The contacts a, 18b, and 18c are all in contact with C1-C2.

Before the card 1 is inserted into the device, the switch 9 is in the OFF state, and all circuits and motors of the device are not supplied with electricity. When the card 1 is inserted into the device, the switch 9 becomes 0N, and electricity is supplied from the power supply 25 to each amplifier 19, 22, 23 except the recording amplifier 20 and the erase bias circuit 21, and the motor 26 through the contacts C1-C2 between this switch and 18b. Supplied. The card is run at a constant speed by a driving roll 4'', and the signal recorded on the card is reproduced by a reproduction head 6, amplified by a reproduction amplifier 19, passed through contacts C2-C1 of a switch 18a, and then sent to the main amplifier. 23 and is reproduced from the speaker 24. When the end of the card is finished playing and the end of the card leaves the switch 9, the switch 9 becomes 0FF and electricity is no longer supplied to all the circuits and motors of the device, and the card is played once. Playback ends.Next, the operating state when playing back endless tape with this device will be explained with reference to FIGS. When set to , switch 1
Through the contacts C1-C3 of 8c, each reproduction amplifier 19, 2
2. Electricity is supplied to the main amplifier 23 and motor 26, and the endless tape 27 is run at a constant speed by the drive roll 4'' and the pinch roller 13, and the signal recorded on the endless tape is read by the playback head 8. is played.

In this case, since the bag 16'' is not provided with a convex portion like the convex portion 10 of the bag 16, the switch 11 is set to 0FF.
In this state, even if the switch 9 is turned ON, that is, even if a card is inserted, the recording amplifier 20 and the erasure/bias circuit 21 do not work, and no recording is made on the endless tape. The signal reproduced by the reproduction head 8 is amplified by the reproduction amplifier 22, guided to the main amplifier through contacts C3-C1 of the switch 18a, and reproduced from the speaker 24. This endless tape 27 can reproduce much longer recorded contents than the one-loop tape 12, but since the beginning and end of the tape are connected, it can be repeatedly reproduced at a long cycle like the reproduction of a one-loop tape. As described above, with the device of the present invention, the recorded contents of the card can be continuously and repeatedly played back in one playback, and if necessary, the recorded contents of the card can also be played back only once, and further, by changing the back. It is possible to repeatedly play back recorded contents that are much longer than cards.

In addition, this device uses the same drive roll to drive the card and drive the single-loop tape or endless tape, making the device very simple to operate.You can power the device just by inserting a card or inserting a puncture. Since it is ON-OFF, operation is very simple. In particular, the bag can be installed in a sliding manner, and simply by pushing it into the device, it becomes operational, so there is no need for two operations, such as setting a cassette and pressing the play button, as with a normal cassette recorder. In this way, this device is a magnetic recording and reproducing device that makes up for the drawbacks of magnetic cards and magnetic tapes and takes full advantage of their advantages.It is easy to operate, and its advantages are especially great as a language learning device. be.
