Abstract

PURPOSE:To improve the reliability of contact by carrying an IC card until the IC card is abutted against a stopper, contacting a brush with the contact of the IC card to read out data, and at the time of discriminating a reading error, slightly changing the stopper position. CONSTITUTION:When the insertion of the IC card is detected by a sensor 2, the IC card is controlled by a CPU 1, carried through a motor 6 until the card is abutted against the stopper and then stopped. Consequently, the brush 3 is descended and contacted with the contact of the IC card to read out the information of the IC card. When a reading error is discriminated, a rotary solenoid 7 is started through the CPU 1 and the stopper position is slightly changed by an interlocking eccentric cam. The information of the IC card is similarly read out, so that the IC card is prevented from the generation of an error due to dust or the like and the reliability of the IC card reader/ writer is improved. When a reading error is decided even after the change of the stopper position, the defect of the IC card is decided and the IC card is returned.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an IC card reading device, and in particular, to an IC card reading device.
The present invention relates to an IC card reading/writing device that reads data through contacts provided on the card and writes new data to the IC card.

[Prior Art] In a conventional IC card reading/writing device, when an IC card is inserted into an insertion slot, the IC card is taken into the inside by a row. When the IC card is transported to a predetermined position, it is stopped by a stopper, and the brush is lowered to contact the contacts of the IC card, and data is read and written through the contacts.

[Problems that J1 Ming is trying to solve] As mentioned above, when the brush is lowered and makes contact with the contacts of the IC card, there may be dirt or dust attached to the contact area, or the contact itself may cause a poor contact. If you have such irritation,
There was a risk that an error would occur in the read data or that the data would not be written correctly.

Therefore, the main object of the present invention is to improve the reliability of the contact by bringing the brush into contact with another position of the contact if a contact failure occurs when the brush is brought into contact with the contact, thereby improving the reliability of the contact. The purpose of the present invention is to provide a writing device.

[Means for Solving the Problems] The present invention is an IC card reading/writing device that reads data through contacts provided on an IC card and also writes data to the IC card. a brush that electrically contacts the contacts of the IC card; a transport means for transporting the IC card; a stopper that stops the IC card at a position where the contacts of the transported IC card contact the brush; A determination means for determining the presence or absence of a reading error by determining the data of the IC card read through the brush, and a determination means for slightly changing the position of the stopper in response to the determination of a reading error, and a determination means for determining the presence or absence of a reading error by determining the data of the IC card read through the brush. The stopper position changing means changes the position and brings the brush and the contact into electrical contact.

[Function] When an error occurs when reading or writing data by bringing the brush into contact with a contact point, the IC card reading/writing device according to the present invention changes the position of the stopper slightly to prevent the brush from touching the brush. The contacts of the IC card are shifted to improve electrical contact between the brush and the contacts.

[Embodiment of the Invention] FIG. 2 is a schematic block diagram showing the electrical configuration of an embodiment of the invention.

First, with reference to FIG. 2, the electrical configuration of an embodiment of the present invention will be described. IC card reading/writing device is cp
Contains ui. A sensor 2, a brush 3, a ROM 4, a RAM 5, a motor 6, and a rotary solenoid 7 are mainly connected to the CPU 1. The sensor 2 detects insertion of an IC card 10 shown in FIG. 3, which will be described later.

The brush 3 electrically contacts the contacts of the IC card 10 and
While giving the data in the C card 10 to the CPU 1,
New data to be written is output to the IC card 10.

The ROM 4 stores a program for controlling the CPU 1 to read and write data to and from the IC card 10. The RAM 5 stores data read from the IC card 10 and stores data to be stored in the IC card 10. The motor 6 is a driving source for transporting the IC card 10 inside. The rotary solenoid 7 is used to slightly change the position of the spring collar 12, which will be explained later in FIG. 5, when the electrical contact between the brush 3 and the contacts of the IC card 10 is not good.

FIG. 3 is a plan view of an embodiment of the present invention, FIG. 4 is a side view, and FIG. 5 is an external perspective view of a stopper position changing means included in an embodiment of the invention.

Next, a mechanical configuration of an embodiment of the present invention will be described with reference to FIGS. 3 to 5. Motor 6 drives roller 8 via belt 9.

The roller 8 inserts the IC card 10 into the IC reading port! It is transported into the loading device. A sensor 2 is provided at one end of the IC card reading/writing device, and this sensor 2
Insertion of the C card 10 is detected. 11 of IC card reading/writing devices! ! Brush 3 and stopper 1 on the end side
2 is provided.

The brush 3 is in electrical contact with the contacts 11 of the IC card 10, and is normally pulled upward.
When the C card 10 comes into contact with the stopper 12 and stops,
It is pulled down and makes electrical contact with the contacts 11 of the IC card 10.

As shown in FIG. 5, the stopper 12 is configured such that one end of the lever is rotatable about a shaft 13, and the tip of the IC card 10 comes into contact with the other end of the lever.

A rotary solenoid 7 is provided near the stopper 12, and an eccentric cam 14 is attached to the rotating shaft of the rotary solenoid 7. When the eccentric cam 14 rotates with the rotation of the rotary solenoid 7, the stopper 1
2 is pressed against the IC card 10 side, and the IC card 1
The stop position of 0 changes minutely.

9 and 9 are enlarged views of the main parts without showing the state of contact between the contacts and the brushes.

Next, with reference to FIGS. 1 to 9, we will explain the specific operation of one embodiment of the present invention. I will clarify.

When the IC card 10 is inserted into the IC card reading/writing device, the sensor 2 detects that the IC card 10 is inserted. The CPU 1 rotates the motor 6 based on the detection output of the sensor 2, and causes the row 58 to transport the IC card 10 inside. The IC card 10 is transported and its tip touches the stopper 12! At time ζ, the CPU 1 stops the rotation of the motor 6 and pulls the brush 3 downward. At this time, the stopper 12 is in the state shown in FIG. 6, and the brush 3 is in the state shown in FIG.
Contact point 11 of 0 is contacted. The CPU 1 reads data written on the IC card 10 via the brush 3 and contacts 11. Then, it is determined whether the read data is normal or not, and if no error has occurred, it is assumed that the data has been read, and the motor 6 is reversely rotated to eject the IC card 10.

However, when the CPU determines that a reading error has occurred, it drives the low resolenoid 7.

When the rotary solenoid 7 rotates, the eccentric cam 14 also rotates and presses the stopper 12 by a small distance a shown in FIG. As a result, the tip of the IC card 10 is pushed by the stopper 12, and the brush 3 is displaced from its contact position with the contacts 11, as shown in FIG. Therefore, the 8th t! ! The brush 3 contacts the contact 11 at the position shown in l.
Even if dirt or dust is attached to contact 1 when it is in contact with the contact 1, data will be read normally if there is no dirt or dust attached at the position shown in Figure 9. .

The CPU 1 changes the contact position between the brush 3 and the contact 11, reads data, and determines whether an error has occurred. If no error occurs, it is assumed that the reading has been performed normally, and the IC card 10 is ejected. However, if an error still occurs even after shifting the contact position, it is determined that the IC card 10 is defective, and the IC card 1o is returned and the series of operations is completed.

[Effects of the Invention] As described above, according to the present invention, when a brush is brought into electrical contact with the contacts of an IC card to read data and a reading error occurs, the IC card is stopped. By slightly changing the position of the stopper for reading and reading data, the contact position between the brush and the contacts is changed, so if dirt or dust is attached to some of the contacts of the IC card, However, by shifting the contact position, it is possible to read the data, and the reliability of the contact can be improved.
