DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic card reader / writer for recording and reproducing information on / from a magnetic card, and more particularly to a credit card ID card reader / writer.

[0002]

2. Description of the Related Art A conventional reader / writer for an ID card for a credit card is a manual reader / writer having a card transport path for about one ID card, or recording / reproducing information by mechanically transporting an ID card. A reader / writer of a type that performs the following is used.

[0003]

SUMMARY OF THE INVENTION As described above, the conventional I
Among the D card reader / writers, the manual type reader / writer is small, but because the ID card is transported by hand, a stable traveling speed for reading / writing cannot be obtained.
There is a problem that the reading rate is low.

A reader / writer of the type which records and reproduces information by mechanically transporting an ID card has a high reading rate because the running speed of the ID card is constant, but a motor for inhaling the card requires a motor. However, there is a problem that the size of the apparatus is increased because of the necessity, and writing may fail due to slippage of the transport of the card.

Further, both the manual type and the card transport type require an encoder for detecting the card transport speed when recording information.

According to the magnetic card reader / writer of the present invention, the recording section is horizontal and the magnetic card is inserted vertically.
A magnetic card insertion slot to be inserted, and the recording of the magnetic card
A magnetic head for recording and reproducing information to and from the unit ;
Before the magnetic head is inserted into the magnetic card insertion slot
A head carrier fixed to the side opposite to the magnetic card
Unit and the magnetic head by fixing the head carrier unit.
The bell is moved parallel to the recording portion of the magnetic card
A motor for driving the bets, the reciprocating motion of the belt, the
Parallel to the recording part of the magnetic card in the head carrier part
And a shaft that guides the movement .

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the present invention, and FIG. 2 is a perspective view showing details of a head carrier portion of the embodiment of FIG.

In FIG. 1, the magnetic card insertion slot 13 is
It is provided on the upper surface of the reader / writer body 12, and I
Place the D card on its recording section (magnetic stripe) horizontally.
And insert vertically . The photodiode 2 and the phototransistor 3 are provided to face each other. When the ID card inserted into the magnetic card insertion slot 13 blocks light from the photodiode 2, the phototransistor 3 detects the light and detects the light. Is notified that the ID card has been inserted. The stepping motor 6 is connected to the control board 14
Controlled by a control circuit mounted on the belt 5
The head carrier unit 4 attached to is driven.
Inserted into the magnetic card insertion slot 13 of the head carrier section 4
The magnetic head 10 is fixed on the side facing the ID card.
Fixed. Shaft 8 is a magnetic card
Provided in parallel with the recording part of the ID card inserted in the insertion slot 13
And is fixed through the head carrier portion 4.
You. Therefore, the stepping motor 6 rotates to move the belt 5
Driving, head carrier portion 4 which is attached to the belt 5, the magnetic head 10 while being guided by the shaft 8
And Ru is parallel to movement and recording portion of the ID card inserted into the magnetic card insertion opening 13.

As shown in detail in FIG. 2, light shielding plates 9 and 11 are provided on both sides of the magnetic head 10 of the head carrier unit 4. The light shielding plates 9 and 11
When the head carrier section 4 reaches both ends of the shaft 8, the home position sensor 7 and the end position sensor 1 (see FIG. 1), each of which is constituted by a transmission type optical sensor, are shielded from light, and the home position sensor 7 and the end position sensor 1 are blocked. Notify the control board 14 that the light is shielded. The home position sensor 7 is provided on the first bit side of the ID card inserted from the magnetic card insertion slot 13 and
Is provided on the last bit side.

Next, the operation of the magnetic card reader / writer configured as described above will be described.

Before inserting the ID card into the magnetic card insertion slot 13, the head carrier unit 4 is at the home position where the light shielding plate 9 shields the home position sensor 7, and the magnetic head 10 is in this position. Does not contact with An ID card is inserted from the magnetic card insertion slot 13 and the photodiode 2 and the phototransistor 3 are inserted.
When the optical path between them is interrupted, the control board 14 recognizes that the ID card has been fully inserted and drives the stepping motor 6. The stepping motor 6 moves the magnetic head 10 at a constant speed along the recording portion (magnetic stripe) of the ID card. When the light blocking plate 11 reaches a position where the light blocking plate 11 blocks the end position sensor 1, the control board 14 stops the movement of the head carrier unit 4. During this time, the magnetic head 10 reads information from the recording section of the ID card and sends it to the control board 14. When this reading operation is completed, the light emitting diode (LED) 15 is turned on,
Inform the user that the reading operation has been completed. LED
When 15 lights up, the user removes the ID card. I
When the D card is removed, a signal is sent from the phototransistor 3 to the control board 14, so that the control board 14 returns the head carrier unit 4 to the home position and turns off the LED 15. This is the initial state.

A similar operation is performed when information is written to the ID card.
エ ン コ ー ダ also functions as an encoder necessary for writing.
From and the rotation speed step angle of the stepping motor 6,
The distance and speed at which the magnetic head 10 moves on the recording portion of the ID card are determined. For this reason, the control board 14 can generate a write clock synchronized with the step pulse sent to the stepping motor 6, and performs a write operation at the timing of the write clock.

[0014]

As described above, the magnetic card reader / writer of the present invention is provided with the shaft for guiding the movement of the magnetic head parallel to the recording portion of the magnetic card, and the motor for driving the movement of the magnetic head. This has the effect that it is possible to record and reproduce information accurately on the ID card only by inserting the ID card into the reader / writer main body. Since it becomes unnecessary, there is also an effect that the size of the device can be reduced.
