[0003]

[Problems to be solved by the device]

 In this conventional apparatus, since the magnetic detection is performed, the punch hole can be detected even if the punch hole is clogged. On the other hand, if the punch holes are clogged, visual confirmation cannot be performed. Therefore, when the position of the punch hole is confirmed with this conventional device, when the punch hole is clogged, there is a discrepancy with the case of visual inspection, and the discrepancy is not judged, and the card user mistakes the value information of the card. There was a problem to recognize.

In view of the above, the present invention makes it possible to judge an abnormality when the punch hole is in an invisible state such as clogging, and accordingly, when the judgment is normal, the punch hole ensures that the card user always recognizes correct value information. The present invention aims to provide an information card recording / reproducing device which can be provided and can be improved in economic efficiency.

[0005]

[Means for Solving the Problems] The present invention is to record and reproduce value data and the like to and from an information card by a recording and reproducing means, and to record the recorded value data and the like on a magnetic layer formed on the surface of the information card. In an information card recording / reproducing device that punches holes in the information display area and displays a guide, the attributes of cards that are provided on the same line as the punching line of the information card and in a different area from the punching area. A magnetic bar code that records information, an optical sensor that detects a punch hole, a common magnetic head that detects a punch hole and a magnetic bar code, and a punch hole position detection of the optical sensor and the magnetic head are judged to be normal. However, punch hole determination means for determining an abnormality when there is a mismatch is provided.

[0006]

[Action]

 In the present invention having such a structure, the position of the punch hole is detected by the optical sensor as well as by the optical sensor. Then, if the punch hole position detections of the optical sensor and the magnetic head match, it is judged as normal, and if they do not match, it is judged as abnormal. The magnetic head also detects a magnetic bar code that records card attribute information.

A magnetic layer is formed in the punched region of the punch hole 23.

FIG. 2 is a block diagram showing a control circuit configuration, and 31 is a control unit. The control unit 31 includes a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory) and the like.

The control unit 31 drives the magnetic recording / reproducing circuit 32 for driving the magnetic head 13, the punch solenoid driving circuit 33 for driving the punch solenoid 12, and the respective optical sensors 18, 19, 20, 21. The first, second, third, and fourth sensor detection circuits 34, 35, 36, and 37 are controlled respectively. That is, the control unit 31 outputs the recording data to the magnetic recording / reproducing circuit 32, and inputs the reproducing data from the magnetic recording / reproducing circuit 32. The control unit 31 also outputs a punch signal to the punch solenoid drive circuit 33. The controller 31 also supplies a motor drive circuit 38 for driving the motor 4 with a motor on / off signal, a brake signal, and a rotation direction signal.

The rotation of the motor 4 is detected by an encoder 39, and an encoder pulse detection circuit 40 for controlling the encoder 39 supplies an encoder pulse to the controller 31 and the motor drive circuit 38.

The control unit 31 also takes in an output signal from a head control circuit 44 that controls the magnetic head 25. The magnetic head 25 is arranged so as to scan the punching line of the punch hole 23 and the reading line of the magnetic bar code 24 by the conveyance of the magnetic card 22.

The control unit 31 includes a counting unit 41 for counting pulse signals from the encoder 39, a position where a punch hole is punched in the magnetic card 22 is a predetermined position, that is, a rear end passage of the magnetic card 22. The conveying distance from the position detected by the second optical sensor 19 until the punching position of the magnetic card 22 reaches the punching portion of the punch solenoid 12, that is, (L1 + Lpn) is the conveying distance per pulse interval. The number of pulses Pp (= L1 + Lpn / Le) is converted based on Le, and the counting means 41 counts the number of pulses Pp to position the magnetic card 22 with respect to the punching position of the punch solenoid 12. Positioning control means 42 for causing the recording / reproducing circuit 32 to drive the magnetic head 13 so as to obtain value data from the magnetic card 22. Regeneration control means 43 is provided to perform the playback.

As shown in FIG. 4, the head control circuit 44 includes a bias power supply 45 for supplying a bias current to the magnetic head 25, an amplifier 46 for amplifying an induced voltage output from the magnetic head 25, It is composed of a waveform shaping circuit 47 for shaping the output of the amplifier 46. A control signal for changing the gain of the amplifier is input to the amplifier 46. That is, the control signal increases the gain of the amplifier in the section where the magnetic head 25 detects the punch hole 23, and lowers the gain in other sections.

In this embodiment having such a configuration, when the magnetic card 22 is inserted into the insertion / ejection port 2 and the tip of the magnetic card 22 is detected by the first optical sensor 18, the control unit 31 is controlled by the motor. A motor ON signal and a rotation direction signal are output to the drive circuit 38 to rotate the motor 4 in the forward direction (counterclockwise rotation in the figure).

When the motor 4 rotates, the encoder 39 detects the rotation, and the encoder pulse detection circuit 40 outputs an encoder pulse signal according to the number of rotations. The rotation of the motor 4 causes the first and second pulleys 5 and 6, the third and fourth pulleys 8 and 10, the first transport roller 9, the first counter roller 16, the second transport roller 15, and the second counter roller. 17 rotate respectively.

As a result, the magnetic card 22 is nipped by the first conveying roller 9 and the first opposing roller 16 and conveyed to the insertion / ejection port 3 side. Then, when the magnetic card 22 passes between the magnetic head 13 and the opposed roller 14, the magnetic recording / reproducing circuit 32 is controlled by the reproduction control means 43 so that the value data etc. (money amount data etc.) recorded on the card is magnetic head. The reproduction data is reproduced in 13 and the reproduction data is supplied from the magnetic recording / reproducing circuit 32 to the control unit 31. When the tip of the magnetic card 22 is detected by the third optical sensor 20, the rotation of the motor 4 is stopped and the conveyance of the magnetic card 22 is stopped.

When punching a punch hole in the magnetic card 22, the punch hole is punched from the rear end of the magnetic card 22 and the distance L 1 from the second optical sensor 19 to the punch hole punching portion of the punch solenoid 12. The distance Lpn to the position is added and subtracted by the transport distance Le of the magnetic card 22 per pulse interval, that is, the pulse number P p is calculated from (L1 + Lpn) / Le and stored in the memory.

Then, from the state where the leading edge of the magnetic card 22 is detected by the third optical sensor 20 and the conveyance is stopped, the motor 4 is now rotated in the reverse direction (rotated right in the figure) to insert and eject the magnetic card 22. Transport to the exit 2 side. When the rear end of the magnetic card 22 is detected by the second optical sensor 19, the positioning control means 42 controls the counting means 41 to start counting the encoder pulse signals from the encoder pulse detection circuit 40. When the counting means 41 counts the number of pulses Pp stored in the memory, the rotation of the motor 4 is stopped and the conveyance of the magnetic card 22 is stopped.

In this way, the predetermined punch hole formation position on the magnetic card 22 is exactly positioned at the punch hole formation portion of the punch solenoid 12. In this state, the control unit 31 controls the punch solenoid drive circuit 33 to drive the punch solenoid 12 and punch the magnetic card 22 with a punch hole. The detection of the punched hole position and the magnetic bar code 24 is performed as follows.

That is, from the state where the leading edge of the magnetic card 22 is detected by the third optical sensor 20 and the conveyance is stopped, the motor 4 is rotated in the reverse direction (rotated right in the figure) to insert and eject the magnetic card 22. Transport to 2 side. When the rear end of the magnetic card 22 is detected by the second optical sensor 19, the positioning control means 42 controls the counting means 41 to start counting the encoder pulse signals from the encoder pulse detection circuit 40.

Then, as shown in FIG. 5, the magnetic head 25 first detects the rear edge of the magnetic card 22, and then the second optical sensor 19 detects the rear edge of the magnetic card 22. The punch hole 23 is also detected first by the magnetic head 25 and then by the second optical sensor 19.

When the rear end of the magnetic card 22 is detected by the magnetic head 25, the positioning control means 42 controls the counting means 41 to start counting the encoder pulse signals from the encoder pulse detection circuit 40.

The encoder pulse count value when the punch hole 23 of the magnetic card 22 is detected by the magnetic head 25 is CHP, and the encoder when the rear end of the magnetic card 22 is detected by the second optical sensor 19. The pulse count value is CHE, the encoder pulse count value when the punch hole 23 of the magnetic card 22 is detected by the second optical sensor 19 is CSP, and the detection position of the second optical sensor 19 and the magnetic head 25 are If the distance from the detection position is d and the count value of the encoder pulse signal between them is Cd (= d / Le), the count value CHE and the punch value when the second optical sensor 19 detects the rear end of the magnetic card 22 It is assumed that the count value CSP when the hole 23 is detected is corrected by CHE-Cd and CSP-Cd and the second optical sensor 19 detects the punch hole 23 at the same position as the magnetic head 25.

In this way, it is checked whether the second optical sensor 19 and the magnetic head 25 detect the punched hole 23 at the same position. If the hole is surely opened like the punch hole 23a shown in FIG. 6, the second optical sensor 19 and the magnetic head 25 can detect the punch hole 23a at the same position.

However, if the hole is clogged due to something like the punch hole 23b or if a tape or the like is stretched, the magnetic head 25 detects the punch hole 23b, but the second optical sensor 19 Cannot be detected because light does not pass through. Therefore, the magnetic head 25 and the second optical sensor 19 are inconsistent in the detection of the punched position. The control unit 31 makes an abnormality determination based on this inconsistency, and informs the operator by an informing means such as a display or a buzzer. In this way, the operator knows that there is something wrong with the punch hole and can check the card again. In other words, the normal judgment is made by coincidence of detection only when the punch hole is in a normal state where the punch hole is always visible, so that the card user can always recognize the correct value information by the punch hole.

When the detection of the punch holes 23 is completed, the magnetic head 25 subsequently detects the magnetic bar code 24 provided on the same line for scanning. This detection signal is supplied to the control unit 31 to determine the attribute of the card.

As described above, since the magnetic head 25 is used not only for detecting the punch hole 23 but also for detecting the magnetic bar code 24, only one magnetic head can be used and the economy can be improved.

By the way, the amplitude level of the detection signal differs as shown in FIG. 7A due to the difference in magnetic flux generated when the punch hole 23 is detected by the magnetic head 25 and when the magnetic bar code 24 is detected. That is, the amplitude level of the detection signal when the punch hole 23 is detected is small.

Therefore, as shown in FIG. 7B, the gain of the amplifier 46 is increased by the control signal when the magnetic head 25 is in the area where the punch hole 23 is detected. As a result, the amplitude level of the detection signal obtained through the amplifier 46 becomes a large amplitude level when the punch hole 23 is detected as in the case where the magnetic bar code 24 is detected, as shown in FIG. 7 (c). ..

Therefore, the output obtained by shaping the waveform of this detection signal by the waveform shaping circuit 47 is an accurate detection signal corresponding to the punch hole punching position and the magnetic bar code position as shown in FIG. 7D. Become.

In the above-mentioned embodiment, the magnetic card is used as the information card, but the information card is not limited to this. For example, a card of a type in which value information is optically recorded and reproduced is also applicable. It is applicable.
