Abstract

PURPOSE:To further shorten the time of a recording and reproducing operation and to enhance the correctness of the recording and reproducing operation of a magnetic signal. CONSTITUTION:When a magnetic card 21 is conveyed up to the fixed position of a frame 15, a control circuit 19 turns a motor 18 to a prescribed direction and moves a mount 12 to the right direction in the figure. When the mount 12 is moved, magnetic heads 11a, 11b which are fixed to said mount 12 are faced with a magnetic stripe 21a on the magnetic card 21 and are moved to the right direction in the figure. A magnetic-signal recording and reproducing circuit 20a arranges that a magnetic signal is recorded on the magnetic stripe 21a using the magnetic head 11a. A magnetic-signal recording and reproducing circuit 20b arranges that a magnetic signal which has been just recorded by the preceding magnetic head 11b is reproduced by using the magnetic head 11a. The control circuit 19 compares both signals and judges whether the magnetic signal has been recorded correctly or not.

It is made to reciprocate twice while facing the magnetic stripe 7a.

During these two reciprocating movements, the magnetic head 1 moves twice from one end of the magnetic card 7 to the other end facing the magnetic stripe 7a, so the magnetic signal recording/reproducing circuit 8 moves twice during the first movement. At times, the magnetic head 1 records a magnetic signal, and during the second movement, the magnetic head 1 reproduces the magnetic signal, and if the magnetic signal is not recorded correctly, recording is performed again.

Furthermore, under a similar configuration, the magnetic head 1
In some cases, the magnetic head is moved back and forth only once, and magnetic signals are recorded and reproduced on the outward and return trips, respectively.

[0008]

SUMMARY OF THE INVENTION The conventional magnetic card recording and reproducing apparatus described above has the following problems. (2) When the magnetic head is made to reciprocate twice as in the former case, the time required for these two reciprocations cannot be ignored. (2) In the latter case, where the magnetic head is moved back and forth once, although the time is shorter than in the former case, misunderstandings may occur in the reproduction results on the return trip due to the directivity of the magnetic head.

The present invention has been made in view of the above-mentioned problems, and aims to provide a magnetic card recording and reproducing device that can further shorten the recording and reproducing time and improve the accuracy of recording and reproducing magnetic signals. .

Embodiments Hereinafter, embodiments of the present invention will be explained based on the drawings. FIG. 1 is a schematic diagram of a magnetic card recording/reproducing apparatus according to an embodiment of the present invention.

In the figure, magnetic heads 11a and 11b
are arranged in parallel to the recording and reproducing direction of magnetic signals, and are fixed to the mount 12. The mount 12 is formed with first and second holes 12a and 12b that penetrate in the direction in which the magnetic heads 11a and 11b are arranged. hole 12
No female thread is formed in b.

A lead screw 13 having a male thread passes through the first hole 12a and is screwed into the lead screw 13, and a shaft 14 which does not have a male thread passes through the second hole 12b. , the lead screw 13 is rotatably supported by the frame 15, and the shaft 14 is rotatably supported by the frame 1.
It is supported non-rotatably at 5.

The lead screw 13 is connected to the pulleys 16a, 1
6b and the rotating shaft 18a of the motor 18 via the belt 17.
The rotary shaft 18a rotates as the rotary shaft 18a rotates. The motor 18 is connected to a control circuit 19 that controls the entire device, and the control circuit 19 controls the rotation of the motor 18.

The control circuit 19 includes the magnetic heads 11a,
The magnetic signal recording and reproducing circuits 20a and 20b are connected to each other, and the magnetic signal recording and reproducing circuit 20a controls the recording and reproducing of magnetic signals by the magnetic head 11a. 20b controls reproduction of magnetic signals by the magnetic head 11b.

The frame 15 is fixed to a magnetic card holding mechanism (not shown) that carries in and out the magnetic card 21 on the side where the magnetic stripe 21a of the magnetic card 21 is arranged. Optical sensors 22a and 22b are arranged at both ends within the movable range of the magnetic heads 11a and 11b, and each optical sensor 2
2a and 22b are connected to the control circuit 19. The control circuit 19 is configured to reverse the rotation direction of the motor 18 based on detection signals from the optical sensors 22a and 22b.

Next, the operation of this embodiment having the above configuration will be explained. When the magnetic card 21 is conveyed to a fixed position on the frame 15 by a magnetic card holding mechanism (not shown), the control circuit 19 rotates the motor 18 in a predetermined direction and moves the mount 12 to the right in the drawing. When the mount 12 moves, the magnetic heads 11a and 11b fixed to the mount 12 move to the right in the figure, facing the magnetic stripe 21a of the magnetic card 21, and the control circuit 19 controls the magnetic signal recording and reproducing circuits 20a and 20b. recording and reproducing magnetic signals.

That is, the magnetic signal recording/reproducing circuit 20a causes the magnetic head 11a to record a magnetic signal on the magnetic stripe 21a, and the magnetic signal recording/reproducing circuit 20b causes the magnetic head 11b to record the magnetic signal just recorded by the preceding magnetic head 11a. Regenerate the signal. Then, the control circuit 19 compares both signals and determines whether or not the magnetic signal has been accurately recorded.

Therefore, while the magnetic heads 11a and 11b move once in the right direction in the figure, the magnetic signal recording work and its confirmation are completed. Therefore, the magnetic signal recording operation can be completed in a shorter time than when the magnetic head 1 is moved back and forth twice as in the conventional case, or even when it is moved back and forth once. Further, since the recording direction and the reproduction direction of the magnetic signal are the same, there is no possibility of misidentification caused by the directivity of the magnetic head.

In the above-described embodiment, the two magnetic heads 11a and 11b are used for recording and reproducing magnetic signals, but the magnetic head 11a erases the magnetic signals and By making the recording of magnetic signals more accurate by using the head 11b for recording and reproducing magnetic signals, it is possible to prevent recording failures of magnetic signals and reduce the possibility of re-recording, which in turn improves the recording of magnetic signals. It is also possible to adopt a configuration that shortens the recording work.

Furthermore, when reproducing magnetic signals, the magnetic signals are reproduced separately in each of the magnetic heads 11a and 11b, so that even if one of them makes a mistake, the data of the other is used to perform one movement. It may also be configured such that playback is completed by a task.

[0026]

As explained above, the present invention records and reproduces magnetic signals only a plurality of times while the magnetic head moves in one direction along the magnetic stripe of the magnetic card. It is possible to provide a magnetic card recording and reproducing device that can perform reproduction in a short time.

[0027] Furthermore, when a preceding magnetic head records a magnetic signal and a following magnetic head records a magnetic signal, the direction of movement of the magnetic head during recording and reproduction is the same, so there is a directivity problem. can be avoided.
