Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording/reproducing device for a magnetic recording card, and more particularly to a recording/reproducing device for a magnetic recording card suitable for repeatedly reproducing the recorded contents of the magnetic recording card.

As shown in FIG. 1, a general magnetic card is constructed such that a magnetic material 3 is provided on the entire surface or in the form of a strip of a card substrate 2 made of paper or plastic, and audio, digital information, etc. are recorded thereon.

Such magnetic recording cards 1 (hereinafter referred to as magnetic cards) are used for language learning, early childhood education, education for the blind, cash payment systems, etc., and their use has been increasing in recent years.

FIG. 2 shows the configuration of a general playback device that records sound on a magnetic card and plays back the sound.

In FIG. 2, the card feed roll 4 is driven by a motor 7, etc., and a card playback head 6 is provided facing the feed roll 4 and pressed by a spring 5 etc., and the signal played back by the playback head 6 is , a card reproduction amplifier 8, and a speaker 9 is further connected to this reproduction amplifier 8.

The switch 10 is 1. It is operated by the magnetic card 1, and while it is in contact with the magnetic card 1, a power supply voltage is supplied from the power supply circuit 11 to the card reproducing amplifier 8 and the motor 7.

Further, a card guide is provided so that the magnetic body portion 3 of the magnetic card 1 can be adapted to the reproducing head 6 and run in the direction of the arrow, but it is omitted in the figure.

The reproducing operation state of the magnetic card will be explained with reference to FIG. hits the switch 10, the switch 10 is turned ON, power supply voltage is supplied from the power supply circuit 11 to the regeneration amplifier 8 and the motor 7, the card feed roll 4 rotates in the direction of the arrow, and the card regeneration amplifier 8 becomes operational.

Furthermore, when the magnetic card is inserted deeply in the direction of the arrow, the magnetic card 1 is driven by the card feed roll 4 and runs at a constant speed, and the signal recorded on the magnetic card 1 is reproduced by the card reproducing head 6. The reproduced signal is amplified by the card reproduction amplifier 8, and the reproduced sound can be heard from the speaker 9.

When the playback of the magnetic card 1 is completed and the end of the magnetic card 1 leaves the switch 10, the switch 10 is turned off, power is no longer supplied to the card playback amplifier 8 and the motor 7, and the magnetic card 1 stops playing once. ends.

Such a magnetic card has a text explanatory text on the card board 2,
Since pictures can be printed, etc., when using them for language learning, etc., it is possible to use visual and auditory skills at the same time.
It has the feature that you can play any card you want to learn as many times as you need (it has the feature of being able to play it as many times as you like, but as mentioned above, in the method of playing it using a general card playback mechanism, the card is running when playing the card, so it is difficult to play the card.) It is inconvenient to see the printed contents, the same card must be replaced many times, and the card is easily damaged.

For this reason, devices have been devised that re-record the recorded contents of a magnetic card onto an endless magnetic recording medium made in one production area and continuously and repeatedly reproduce the recorded contents of the card from this endless magnetic recording medium (for example, Showa 52-3778
No., Jitsugan No. 52-3779).

An example of such a playback device is schematically shown in FIGS. 3 and 4.

That is, in FIG. 3, the magnetic card 1 is driven by the card feed roll 4 in the direction of the arrow shown in the figure, and the card reproducing head 6 reproduces the recorded signal of the magnetic card 1, and at the same time, the reproduced signal is transferred to the same feed roll 4 and the pinch roller 12. A recording head 14 records on a one-loop magnetic tape 13 driven by a magnetic tape, and a reproducing head 15 repeatedly reproduces the recorded signal from this one-loop tape 13.

In this case, the erasing head 16 operates simultaneously with the recording head 14 and erases the signal previously recorded on the one-loop tape 13.

Now, in such a device, 1 is used only when playing cards.
It is necessary that a recording circuit that records the reproduced signal on the loop tape 13 works, and that this recording circuit is turned off after the card reproduction is completed so that the signal recorded on the one loop tape 13 can be repeatedly reproduced.

To achieve this, in the example of the above-mentioned application, as shown in FIG. Then, when the magnetic card 1 is inserted, the switch 10' is turned on and power is supplied to the card reproduction amplifier 8 and the recording circuit 18 of the 1-loop tape 13, only while the magnetic card 1 passes through the switch 10'. The recording signal of the magnetic card 1 is transferred to one loop tape 13 by the recording head 14.
At the same time, the recording signal is reproduced by the reproducing head 15.

When magnetic card 1 leaves switch 10', switch 1
0' is turned OFF, power is no longer supplied to the magnetic card reproduction amplifier 8 and l loop tape recording circuit 18, and 1
The signal recorded on the loop tape 13 is repeatedly reproduced by the reproduction head 15.

In another example, the switch 10' and the switch 17 are made to work simultaneously by inserting a magnetic card,
When the magnetic card is in contact with the switches 10' and 17, all circuits of the device are powered on and the magnetic card is played.
Recording on Loop Tape One loop tape is played back, and when the playback of the magnetic card is completed, the terminal end of the magnetic card is separated from the switches 10' and 17 and turned off, turning off all power to the apparatus.

That is, the signal recorded on the magnetic card is reproduced only once from the one-loop tape through the reproduction head 15, and then the power of the apparatus is turned off.

When repeatedly reproducing a signal recorded on a 1-loop tape, switch 17' (
This is done by pressing the button (omitted in Fig. 3).

Now, with the method of turning on the power to the motor and 1-loop tape playback circuit before inserting the card, as in the example above, once the power is turned on, the 1-loop tape will be played regardless of whether or not a card is inserted. If a battery is used as a power source for such a device, the switch 17 should be turned off each time to prevent the battery from being consumed more than necessary and to prevent the student from learning the next card. There is an inconvenience that you have to do.

Further, in a system in which all circuits are turned on and off by a card, one loop tape cannot be repeatedly played unless the card passing compound switch is pressed.

An object of the present invention is to provide a magnetic recording/reproducing device that eliminates the above-mentioned drawbacks.

Next, the present invention will be described in detail with reference to FIGS. 5, 6, and 7 of the accompanying drawings.

FIG. 5 schematically shows a magnetic recording/reproducing device as an embodiment of the present invention, in which a card is inserted into the device, the card is played back, and at the same time the playback signal is recorded on one loop tape. This is a sideways view of the state in which recorded contents are being played back from a loop tape.

FIG. 6 schematically shows a state in which the content recorded on the one-loop tape is being repeatedly played back after the playback of the card has been completed.

FIG. 7 is a block diagram showing the electrical circuit of the device of the present invention.

The differences between the structures in Figures 5 and 7 and those in Figures 3 and 4 are as follows:
Switches 10a, 10b are provided which are operated simultaneously by the card and supply power to all circuits of the device, and a switch 17 which supplies power only to the motor 7 and the one-loop tape playback amplifier 19 after the card has passed the feed roll. Since the other configurations are the same, the explanation will be omitted.

The operating state of this device will be explained according to FIGS. 5 to 7. First, as shown in FIG.
When the card is inserted into the device in the direction of the arrow with the card in contact with the card playback head 6, the leading edge of the card touches the switches 10a and 10.
b, the power supply voltage is supplied from the power supply circuit 11 to the reproduction amplifier 8 and the loop tape recording amplifier 18 by the switch 10a, and to the motor 7.1 and the loop tape reproduction amplifier 19 by the switch 10b. Ru.

At this time, the card feed roll 4 rotates, the 1st loop tape 13 also runs in the direction of the arrow, and at the same time the 1st loop tape recording circuit 18 becomes operational, and the erase head 16 records on the 1st loop tape first. The signal is erased.

Both the card reproducing amplifier 8 and the loop tape reproducing amplifier 19 are in the reproducing state, but since the previous recording signal of the one loop tape 13 has been erased by the erasing head 16, no reproduced sound can be heard from the speaker 9.

When the card is inserted deeper in the direction of the arrow between the card reproducing head 6 and the card feed roll 4, the card is driven by the card feed roll 4 and runs at a constant speed, and the signal recorded on the card 1 is The signal is reproduced by the reproduction head 6, amplified by the reproduction amplifier 8, guided to the one-loop tape recording circuit 18, and recorded on the one-loop tape 13 by the one-loop tape recording head 14.

The signal recorded on the loop tape 13 is sent to the recording head 14.
The reproduced sound is reproduced by the adjacent one-loop tape reproduction head 15, amplified by the one-loop tape reproduction amplifier 19, and reproduced from the speaker 9.

As the card 1 advances further, the tip of the card hits the switch 17 and the switch 17 is turned on, but the switch 10b is already turned on.
Since power is on to the loop tape reproduction amplifier 19 and motor 7, the operating status remains unchanged.

When the card advances further and the playback of the card is completed and the end of the card 1 leaves the switches 10a and 10b, the switches 10a and 10b are turned OFF as shown in FIG. Power is no longer supplied and current no longer flows to the erasing head 16 and recording head 14, and recording on the loop tape ends.

As the card advances further, the card is removed from the card feed roll 4, and when the card hits the switch 17, the card stops.

In this state, the switches 10a, 10 in FIG.
b is OFF and switch 17 is ON, so 1
Since only the loop tape reproduction amplifier 19 motor 7 is powered on, the 1 loop tape 13 continues to run as it is.
The signal recorded on the loop tape 13 is repeatedly reproduced by the one-loop tape reproduction head 15, and the reproduced sound can be heard from the speaker 9.

Next, when card 1 is removed from the device, switch 17 is turned OFF.
F, power is no longer supplied to the device's electrical circuit, and playback of the 1-loop tape stops.

In this embodiment of the present invention, the card feed roll and the one-loop tape feed roll are configured with the same motor and the same feed roll, but the same applies to an apparatus in which the two feed sections have completely independent configurations. It can have a function.

Furthermore, in the embodiment described above, the recording signal of the card is re-recorded on the 1-loop tape by the recording head, but the card is recorded using the so-called contact magnetic transfer method, in which the magnetic surfaces of the card and the 1-loop tape are closely aligned and a transfer magnetic field is applied. The functions of the present invention can also be effectively used in a device that re-records signals on a single loop tape.

In addition, if you want to listen to the playback sound when the card is in your hand, you can install another switch in the device in parallel with switch 17, and if necessary, press this switch to perform the same operation as switch 17. You can play loop tapes.

As described above, with the device of the present invention, simply by inserting the card to be played into the device, the device enters the operating state and starts playing the card, and by leaving the card in that state, the device needs to play back the sound. It can be played repeatedly repeatedly for as many times as necessary, and the playback can be stopped simply by removing the card from the device, making it ideal for learning that requires repeated memorization, such as language learning.
