Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording and reproducing device for a magnetic recording card, and in particular, a recording and reproducing device for a magnetic card suitable for repeatedly reproducing the recorded contents of a magnetic recording card (hereinafter referred to as a magnetic card). and its method.

FIG. 1 shows the configuration of a general magnetic card. As shown in Figure 1, a magnetic card 1 has a paper or plastic card substrate 2.
A magnetic material 3 is provided on the entire surface or in the form of a strip, and audio, digital information, etc. are recorded thereon. Such magnetic recording cards can be used for language practice, early childhood education, blind education,
It is used in cash payment systems, etc., and its usage has been increasing in recent years. FIG. 2 shows a general reproducing mechanism for reproducing this magnetic card. That is, magnetic card feed row 3
There is a reproducing head 6 facing the roll 4 and pressed by a spring 5, and the magnetic card is sent in the direction of the arrow with the magnetic surface in contact with the reproducing head 6 between the roll 4 and the reproducing head 6.
Insert the magnetic card between the two and run the magnetic card to perform playback. 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 when a magnetic card is used for language learning, the user inserts the card into the feeding mechanism while looking at the characters, explanatory text, pictures, etc. printed on the magnetic card, and records the information on the magnetic material 3. By listening to the content, language learning is done by using the visual and auditory senses at the same time.

In this way, magnetic cards cannot record and play back audio for long periods of time, but they do allow random access and can print text, explanatory text, etc. on each card, allowing you to listen to the same card over and over again. It is ideal for pronunciation of foreign language words, conversation practice, etc.

Now, in the method of reproducing a magnetic card using the above-mentioned reproducing mechanism, since the card is running when the card is reproduced, it is inconvenient to see the contents printed on the card.
When playing the same card repeatedly, the card must be replaced many times, which has the disadvantage that the card is easily damaged. For this reason, there are methods to play the sound by keeping the card still and moving the magnetic head, and methods to play the card repeatedly by pressing a button to move the card backwards to the playback start position after the card is played to the end using the card feeding mechanism described above. However, they all have complicated mechanisms and require time to return the head or card, so they have the drawback of not being able to reproduce audio continuously. 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. (Jet Application No. 170883/1983, Application No. 3779/1983)
. In Utility Model Application No. 170883/1983, as shown in Fig. 3, one loop tape (magnetic tape) is run using a playback and tape running mechanism of a force set recorder that has been widely used in the past, and the running of this tape is controlled. At the same time, when the card is driven once, the magnetic surface of the tape card is brought into close contact with the transfer head 7 to magnetically transfer the recording signal of the card onto the loop tape, and the recorded content of the drive is transferred from the loop tape to the playback head 8. It is a device that reproduces
In No. 79, as shown in Figure 4, Utility Application No. 51-1708
Like No. 83, the card is driven using the running of the 1-loop tape, and the recorded contents of the card are played back by the playback head 6, which is in contact with the magnetic surface of the card, and at the same time, the recording head 9, which is in contact with the 1-loop tape, is played back. These devices record on a single loop tape and play it back on the adjacent playback head 8. Both of these devices are very simple devices, and by simply placing the card in the device once, you can listen to the recorded content while keeping the card at hand. It has the great advantage of being able to be played continuously and repeatedly, and even force set tapes can be played by simply replacing the 1 loop tape pack with the conventionally widely used force set tape. It must be larger than the force set tape, a guide for running the card is required, and the conventional force set recorder must be modified. In the method of the present invention, by separately providing a simple card playback mechanism, the recorded contents of the card can be continuously and repeatedly reproduced from the power set recorder without changing the conventional power set recorder or by simply changing the configuration of the head.

Embodiment 1 An embodiment of the present invention will be described with reference to the drawings. FIG. 5 is a functional diagram showing an example of the case where the function of the present invention is performed using a conventional force set recorder as it is. .

That is, in FIG. 5, the dotted line a indicates the magnetic card reproducing machine used in this device, 10 indicates a one-loop tape cassette that can be set in a conventional force set recorder, and the dotted line b indicates the reproducing section of the conventional force set recorder. It is expressed functionally. The magnetic card player a is manufactured separately from the force set recorder and is itself constructed as an integrated unit.

The magnetic card reproducing machine a includes as basic elements a card feeding roll 4 rotated at a constant speed by a motor 12, and a card reproducing head 6 disposed opposite to this roll 4.
A switch 11 that is turned on and off when the magnetic card 1 is inserted and passed; a power source 17 that supplies power to the motor 12 and other circuits when the switch 11 is turned on; and a card reproducing head 6.
an amplifier 13 that amplifies the signal reproduced from the recording amplifier 13, a recording amplifier 15 that supplies this amplified signal to the recording head 14 with erasure (recording head 14'') in the one-loop cassette 10;
It consists of a bias oscillator 16 for supplying erasing current and bias current to the recording head with erasure (erase head 14'), and conductors connecting these as shown. The magnetic card 1 has at least one track of magnetic film along the direction of the arrow in the figure, on which magnetically recorded contents are stored (see Figure 1), and the track is guided by a guide means (not shown). is arranged so that it passes just past the card reproducing head 6. The other points are as already mentioned and need not be discussed here. In Fig. 5, when the magnetic card 1 is first inserted into the player, the switch 11 is activated, and the motor 12 and amplifier 1 are activated.
3. A power source 17 is supplied to the recording amplifier 15 and the oscillator 16, respectively. The magnetic card 1 is sent in the direction of the arrow by the card feed roll 4 while bringing its magnetic film into contact with the card playback head 6, and a recording signal is supplied from the amplifier 15 to the recording head 14 with erasing. At the same time, a bias current and an erase current are supplied from the oscillator 16 to the recording head with eraser 14.
Next, the one-loop tape cassette 10 will be explained.
A single loop tape 18 with the magnetic side facing outward is housed in a force set case to form an independent force set similar to conventional force set tape. A pair of holes 27 are formed in the one-loop tape cassette so that it can be installed directly into the force setting tape mounting section of a normal force setting recorder.

That is, the external dimensions of the one-loop tape cassette 10 are the same as those of a conventional standard force set, or are dimensioned so that the force set mounting portion can be used as is. power set 10
A tape guide 19 is arranged in the internal space of the tape guide 19, and a one-loop tape 18 is freely runnable therethrough. The recording head 14 with erasing described above is fixed in contact with the outer surface of the one-loop tape 18. One loop tape cassette 10 has a playback head 2 provided in a playback section b of a cassette recorder i.
Of course, recesses and holes similar to conventional force sets are provided to allow the 0v capstan 21 and pinch roller 22 to be properly associated with the one loop tape 18.

To explain the operation for continuously and repeatedly reproducing the recorded contents of a magnetic card, a 1-loop tape cassette is inserted into the mounting section of the power set recorder, and a connection is made between the recording head with erasure 14 and the card player a. (connections can be made by any means) and the power set recorder is placed in the playback state. Next, when the card 1 is inserted into the player a so that the magnetic surface of the magnetic card 1 on which recording is in contact with the card playback head, the switch 11 is turned ON by the card 1, and the erase head 14' of the recording head 14 with erase is turned on. A current flows through the tape, erasing the signal recorded on the 1-loop tape.

Furthermore, when the card 1 is inserted between the card feed roll 4 and the card playback head 6, the card 1 is run at a constant speed by the card feed roll 4, and the signal recorded on the card is played back by the card playback head 6. , regenerative amplifier 1
3. 1 loop tape cassette 10 via recording amplifier 15
One loop tape is recorded by the recording head 14'' located inside the card.The recorded signal is played back by the power set tape playback head 20, passed through the playback amplifier 23, and is emitted from the speaker 24. runs, the end of the card passes the switch 11, and when the playback of the card is completed, the switch 11 becomes 0FF, and the erasing current and recording current flowing to the erasing recording head 14 stop, and recording on the 1-loop tape ends. Finish. Now, if you adjust the card length to the length of one loop tape, the recording content of the card will be recorded on exactly one loop tape while one loop tape rotates, and will remain as it is, so the recorded content will be one loop tape length. Every time the roof fly tape rotates, it is continuously and repeatedly played by the power set tape playback head 20. In this way, just by playing the card to be played by the player, a new one is recorded on the loop tape. The contents are recorded and played back continuously and repeatedly.The above embodiment is an attempt to perform the intended function without modifying the conventional power set recorder at all, and the card player and the 1-loop tape cassette are connected by a lead wire. The feature of this embodiment is that the card reproducing machine has a simple structure with a card reproducing mechanism, since the magnetic card can be continuously and repeatedly reproduced by using the force set recorder that has been widely used in the past. There is no need for a built-in speaker and a small and inexpensive device can be used.Example 2 In the above example, the power set recorder is erased in a single loop tape cassette in order to perform the intended function without any modification. An attached recording head is provided, and this head 14 is installed at the position of the erasing head for degaussing the cassette tape in the playback section b, as shown in Figure 6, and a connector 25 is installed at an appropriate location on the power set recorder to connect the card player. It may also be possible to connect to a.

The feature of this embodiment is that a recording head with erasing is installed in place of the erasing head of the power set recorder, and it is not necessary to use a single loop tape cassette with a lead wire by simply attaching a connector that connects this head to a card player. Since there is no need to provide a recording head with erasing in the one-loop tape cassette, the one-loop tape cassette can be made at low cost. In both embodiments 1 and 2, the card player a alone cannot perform continuous and repeated playback, but it can play cards, so the card player alone can also be used as a speaker.
You may also be able to listen to the reproduced sound using earphones or the like.

Also, the playback amplifier, recording amplifier, bias oscillator, or a part thereof of the card player may be provided within the power set recorder, or may be provided as a separate set between the card player and the power set recorder. good. Embodiment 3 In the above embodiment, the card reproducing machine and the power set recorder are separate, but they may be integrated as shown in FIG.

In this case, not only is there no need for a line connecting the card player and the force set recorder, but there is also the advantage that the motor that drives one loop tape and the motor that drives one card can be used in common, as shown in the figure. Embodiment 4 Furthermore, as shown in FIG. 8, the card reproducing machine may be formed into a groove that can be detachably attached to the power set recorder, and the electric circuit may be automatically connected to the power set recorder.

Embodiment 5 A microphone 26 is connected in parallel with the magnetic card playback head 6 as shown in FIG. 9 to the device described above, and the user's voice can be recorded on a single loop tape by mixing it with the playback sound of the magnetic card. You can do it like this.

In this case, if you put the model pronunciation on a card, you can listen to the pronunciation and record your own voice at the same time, and after the 1-loop tape has rotated once, you can record how many times the model pronunciation and your own pronunciation are repeated. It is possible to continuously and repeatedly compare the results, allowing for more effective learning. As described above, according to the method (device) of the present invention, a simple card player and a one-loop tape cassette can perform functions that cannot be achieved with conventional power set recorders, namely, random access playback, single-operation recording, and continuous repeat playback. Therefore, it is very effective for educational learning that requires memorization (especially language practice).
