[Problem that the invention seeks to solve]

A conventional magnetic card dedicated to a credit card with a thickness of approximately 0.8 m+a and a magnetic card commonly used, for example in transportation, with a thickness of approximately 0.25 mm and a credit card with a thickness of approximately 0.8 m++++ respectively. leader/
In the writer device, the power supply voltage of the detection circuit using a normal sensor is DC5V, while the power supply voltage of the drive motor that rotates the feed roller with one step deceleration and the normal magnetic head is DC12V, and the power supply voltage is DC12V to operate the device. The analog circuit used was two power supplies: 5V and 12V.

In addition, there are existing devices that are equipped with a shutter in the magnetic card insertion/extraction slot, and devices that are equipped with a means for making a predetermined hole in the magnetic card, but these devices do not utilize a driving source, especially a solenoid. The drive source uses the same DC 12V as the drive motor in order to ensure the required shearing force.

Therefore, when a credit card function is added to a conventional magnetic card reader/writer device used in transportation, etc. using the conventional technology, there is a problem that the device configuration becomes large and cannot be accommodated in the conventional space.

Means for Solving Problem c] According to FIG. 1, the present invention aimed at eliminating the above problem includes a pair of magnetic card guide rails 31a communicating with the left end or right end of the magnetic card insertion/extraction opening 23a. , 31b, a plurality of sensors 66a to 66e for ejecting the magnetic cards traveling along the rails 31a and 31b, and the rail 31
The upper surfaces of the magnetic cards inserted into the slots 23a and 31b come into contact with each other sequentially from the side closest to the slot 23a. A rail 31a is provided near the second and third feed rollers 25 to 27 and the second feed roller 26.

Second. The first feed roller facing the third feed rollers 25-27. Second. A third pad roller 49 is provided with push-up means for pushing up the lower surface of the magnetic cards inserted into the rails 31a and 31b, and is opposite to the fourth band roller 41, and has the same operating voltage as the detection circuit of the sensors 66a to 66e. A magnetic head 33 that reads/writes using a DC voltage, and a first magnetic head 33 that is driven by the DC voltage and has a multi-stage deceleration means. A first motor 2 that rotates the second and third feed rollers 25 to 27
9, a second motor 30 driven by the DC voltage, a means 32 for making a through hole in the magnetic card by driving the second motor 30, and an opening/closing shutter for the insertion/extraction opening 23a driven by the DC voltage. This magnetic card reader/reader is characterized by comprising an electromagnet 28 for operating a magnetic card 24.

[Effect]

According to the above means, the drive motor of the feed roller is reduced in size by using a two-step deceleration, and the motor is connected to the motor that serves as the drive source of the means, the magnetic head, and the electromagnet that serves as the drive source of the shutter. By making it possible to use the same power source as the sensor circuit, for example, a magnetic card reader/writer device with different functions for transportation and credit cards can be integrated into a device that is approximately the same size as a conventional device.

As a result, when a new magnetic transportation card is introduced, it is now possible to pay using a credit card on the spot, making the use of transportation magnetic cards even more convenient.
