Further, when the stopper signal V5 is input from the sensor S3 and the card type signal at that time is the type signal V1 for the contact card C1, the control means 4 energizes and drives (turns on) the electromagnetic solenoid 22; When the card type signal is the type signal V2 for the proximity card C2, a constant voltage and a voltage that changes in accordance with the information are supplied to the connectors 29 and 30. Further, when the transmission / reception of information is completed, the control means 4 cuts off the power supply to the electromagnetic solenoids 22 and 131 to turn them off, and drives the drive motor in reverse.

The operation of the IC card reader 1 having such a configuration will be described. First, the magnetic card reader 100 shown in FIG.
When the IC card C is input into the magnetic card reader 100, a drive motor (not shown) is started, and while the IC card C is being conveyed through the magnetic card reader 100, recording / recording of magnetic information is performed by a magnetic head (not shown).
Playback is performed.

When the drive motor starts, its rotation is transmitted to the transport mechanism 12 via the belt 127 and the pulley 123, and the transport roller pair 120, 121 is driven to rotate. For example, an IC inserted in the magnetic card reader 100
If the card C is a contact card C1, the type signal V1 is input to the control means 4, and the contact card C1 is conveyed to the card travel path 9 as shown in FIG.

The transported contact card C1 is first nipped by the transport roller pair 120 and transported in the card travel path 9. Then, it is detected by the sensor S2 and the sensor S2
When the stop signal V4 is output from the motor, the drive motor stops, the electromagnetic solenoid 131 is turned on, and the movable piece 13
1a moves in the direction indicated by arrow b in FIG. When the movable piece 131a moves, the stopper 1
33 rotates from the evacuation position indicated by the solid line to the entry position indicated by the two-dot chain line, and the leading end 133b contacts the leading end of the conveyed contact card C1 located in the card running path 9.

The operation of the movable piece 131a is detected by the sensor S3.
Is detected, a stopper signal V5 is output, the electromagnetic solenoid 22 is turned on, and the movable piece 22a is retracted in the direction of arrow a in FIG. With this operation, the rotating arm 24 is displaced about the shaft 23 from the separated position shown by the two-dot chain line to the contact position shown by the broken line, and the contact block 10 is lowered.
Then, as shown in FIG. 6, the contact 10a projecting from the contact block 10 comes into contact with the contact terminal 2 of the contact card C1, which is already stopped in the card running path 9, and the contact card C
1 is input and output.

On the other hand, if the inserted IC card C is the proximity card C2, the type signal V2 is inputted to the control means 4, and the proximity card C2 is moved to the card running path 9 as shown in FIG.
Transported to The conveyed proximity card C2 is first nipped by the conveyance roller pair 120 and conveyed in the card travel path 9. Then, it is detected by the sensor S2 and the same sensor S
2 outputs a stop signal V4, the drive motor stops, and the electromagnetic solenoid 131 is turned on.
31a moves in the direction indicated by arrow b in FIG. When the movable piece 131a moves, the stopper 133 pivots from the retreat position shown by the solid line to the approach position shown by the two-dot chain line via the lever 132, and the leading end 133b enters the card travel path 9 and is shown in FIG. As described above, the proximity card C2 is stopped so that the non-contact terminal 3 and the IC module 11 are in contact with the proximity card C2.

When the sensor S3 detects the operation of the movable piece 131a, a stopper signal V5 is output, and the connectors 29 and 3 are output.
A voltage is supplied to the coils 26, 26, 27, 27 and the plurality of metal plates 28 via the zero. Then, the coils 26 and 2
6, 27, 27 and the coils 5, 5, 6, 6 are generated by changing the electromotive force by a variable voltage that is changed and supplied according to information, and the potential difference (voltage) due to the change is generated. Is generated, a potential difference (voltage) is generated between the metal plate 28 and the metal plate 7 due to a change in capacitance, and the potential difference is converted to input / output information to / from the proximity card C2.

When the input / output of the information on the contact card C1 and the proximity card C2 is completed, the electromagnetic solenoids 22 and 1 are terminated.
The power supply to the power supply 31 is turned off. Then, the stopper 133 and the contact block 10 are retracted from the card travel path 9 by the spring force of a spring (not shown), and the drive motor is driven in reverse to the time of conveyance. By this reversing drive, the IC card C in the card running path 9 moves backward toward the insertion side, and is ejected from the IC card reader 1 and the magnetic card reader 100 connected thereto.

As described above, in the IC card reader 1, the contact block 10 for inputting and outputting information by contacting the contact terminal 2 of the contact card C1 and the non-contact terminal 3 of the proximity card C2 are provided.
The contact card C1 and the proximity card C2
It is possible to cope with both. In addition, the contact card C1 and the proximity card C2 conveyed on the card running path 9
Is stopped at a predetermined position in the card travel path 9 by one stopper 133, so that it is not necessary to separately provide the stoppers 133.

Further, the contact block 10 and the IC module 11 are provided to face each other with the card running path 9 interposed therebetween, and when the card is stopped, the contact terminal 2 and the contact block 10 and the non-contact terminal 3 and the IC module 11 face each other. The stop position of the contact card C1 and the proximity card C2 becomes the same when the IC card C is stopped by contacting the stopper 133. Therefore, the range of the stopped card occupying the card travel path 9 becomes narrower than the case where the card stop positions are different, so that the total length of the card travel path 9 can be shortened, and the IC card reader 1 can be downsized.

If the stop signal V4 and the stopper signal V5 are output from the sensors S2 and S3 and the type signal V1 corresponding to the contact card C1 is not output from a sensor (not shown), the electromagnetic solenoid 22 does not turn on. It is possible to prevent the contact block 10 from entering the card running path 9 when the C2 is inserted, and it is possible to reduce the running resistance to the adjacent card C2. Further, the electromagnetic solenoid 22
Is a stopper 133 disposed on the front end side of the card running path 9.
Does not operate, that is, the contact card C1 is not turned on unless the stopper signal V5 is output.
Until the contact block 33 abuts, the contact block 10 is retracted from the card traveling path 9, and the traveling resistance can be reduced even during traveling of the contact card C1.

In the present embodiment, the contact block 10 is arranged above the card traveling path 9 and the IC module 11 is arranged below the card traveling path 9. However, the present invention is not limited to this. When the sheet 2 is conveyed while being positioned on the lower surface side of the card travel path 9, the contact block 10 is arranged below the card travel path 9, and the IC module 11 is arranged above the card travel path 9. In short, it is important to arrange the contact block 10 in a direction that can contact the contact terminal 2 and to provide the IC module 11 on the side facing the contact block 10.

In this embodiment, both the magnetic card reader 100 and the IC card reader 1 are controlled by the control means 4, but it is also possible to control the IC card reader 1 alone. In this case, a card sensor (not shown) that outputs the card type signals V1 and V2 is provided near the pair of transport rollers 120, and a drive motor (not shown) is disposed in a part of the transport mechanism 12, so that the IC card reader 1 alone can be used. Processing becomes possible.
