Abstract

PURPOSE:To shorten processing time by optically reading the surface of an IC card with an image sensor, and executing a discrimination of the IC card by comparing that read-out contact pattern with a registered contact pattern. CONSTITUTION:An optical read-out means 6 is provided near a card push-in opening, and a light source is made incident from diagonally above the IC card 3. An image sensor 7 is attached at a position where the regularly reflected light beam of the surface of the card can be received. Thus, the flat part of the card becomes bright, the upper part of the gold plate of the contact point possessing a protruded or an indented form becomes even brighter, foreign matter stuck on the contact point becomes darker than the gilded upper part, and the respective contact point shapes are displayed as an image information. Then, after this is image information is read by the image sensor 7, it is compared to the registered contact pattern, and the IC contact points and the presents of foreign matters stuck can be checked. Thus, right after the card 3 is pushed into the automatic teller device, whether or not the card is the IC card 3 can be judged immediately, and the transaction processing time can be shortened.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic transaction processing device using a card as a medium;
In particular, the present invention relates to an automatic cash transaction processing device that handles IC cards.

[Conventional technology]

The conventional technology writes that it is an IC card in the magnetic stripe of the card, and communicates and verifies the data content of the read magnetic stripe with a center.
If the above method is not possible, the IC card is determined to be a regular IC card by transporting the card to the conductor that contacts the IC card reader, and then bringing the contact part of the IC card into contact with the conductor. It's a card. It was determined whether or not.

Further, the invention disclosed in Japanese Patent Application Laid-Open No. 59-3689 detects read data output from a magnetic card and uses the output content to connect an IC card chip to an electrode control section. It is a card read method that can also be used as a card.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, the means for determining that it is an IC card requires time to access the written information of the IC card, which increases the processing time of the automatic transaction processing device. There was a problem. Furthermore, there is also the problem that if foreign matter adheres to the contact portion of the IC card, poor contact with the conductor occurs.

The present invention instantly determines whether or not an IC card is an IC card when it is inserted into an automatic transaction processing device, and also checks for foreign matter or damage on the contacts of the IC card to check the connection between the IC card and the conductor. In addition to providing data to control the amount of card movement to prevent accidents due to poor contact, the system also provides an automatic transaction processing device with a function to eject or take cards with abnormal contact patterns out of the device. The purpose is to

[Means for Solving the Problem] The above object is to provide an optical reading means near the card insertion slot, read the unevenness of the surface and contact portion of the IC card, and register the contact pattern obtained from the read data. This is achieved by an automatic transaction processing device having a means and structure for identifying an IC card by comparing the contact pattern with the contact pattern of the IC card, and for processing an abnormal IC card.

[Operation] In the present invention, a line light source is irradiated from diagonally above the IC card, and an image sensor is mounted at a position where it can receive specularly reflected light from the card surface. With this configuration, the flat surface of the card is bright, and the upper part of the gold plating of the convex or concave contacts is even brighter, and the foreign matter attached to the contact is darker than the upper part of the gold plating, so that the shape of each contact can be used as image information. Is displayed. After reading this with an image sensor, compare it with the registered contact pattern.
It is possible to check whether there is any foreign matter attached to the C contact.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4.

FIG. 1 shows a schematic diagram of the inside of a card processing mechanism l of an automatic transaction processing device according to the present invention. In FIG. 1, reference numeral 2 denotes a card slot, through which the IC card 3 is taken into the card processing mechanism 1.

The card 3 is conveyed by a roller 5 which is rotationally driven by a motor 4. Reference numeral 6 denotes an optical reading section, which corresponds to the "means for optically reading the surface of the iC card" according to claim 1, and is capable of reading not only the contact section of the card 3 but also the embossed characters and the patterns and colors printed on the surface. The image sensor 7 has a function of reading optical characteristics such as the contact part 14 of the card 3, as well as an image sensor 7 and an LED 8 that read embossed characters, etc.
It is composed of light receiving elements such as.

A conductor 9 contacts the contact portion of the card 3, and is driven by a solenoid 10 to move up and down.

The magnetic stripe information on the card 3 is read by the magnetic head 11.

FIG. 3 shows a situation in which the contact portion 14 of the card 3 and the uneven image of a foreign object are read. In FIG. 3, the optical axis angle at which the LED array 8 illuminates the surface of the card 3 and the image sensor 7 are shown.
is equal to the optical axis angle at which the reflected light from the card 3 is received,
An optical system is arranged to cause specular reflection on the upper surface of the card 3.

That is, the light emitted from the LED array 8 is cut by the slit 12, and the light is adjusted in a line to illuminate the card 3. On the other hand, on the image sensor 7 side, a lens 13 is arranged to receive line light from the top surface of the card 3.

The card 3 and the optical reading section 6 while maintaining the above positional relationship.
When the image sensor 7 is moved relative to the card 3 (the optical system is moved in FIG. 3), the amount of light received by the image sensor 7 increases and becomes brighter for the flat part of the card 3, and more for the contact part 14. The contact portion 14 and the foreign object 15 can be identified by the main control unit 18 from the difference in brightness and darkness.

FIG. 2 shows a block diagram of the above-mentioned image signal processing, in which the image sensor control section 16 reads the signal of the image sensor 7 by receiving light from the LED 8,
This signal is processed by the contact pattern processing section 17 and adjusted to a predetermined format, and then compared with the registered contact pattern by the main control section 18.

The above operation will be explained with reference to the overall flowchart of the automatic transaction processing device shown in FIG.

When the card 3 is inserted into the card insertion slot 2, the motor 4 rotates, drives the roller 5, and takes the card 3 into the card processing mechanism 1. While the card 3 passes through the optical reading unit 6, the shape of the contact portion 14 of the card 3 is read as image sensor information (1.01).

Compare and check whether the read contact pattern is the same as the registered contact pattern of the IC card 102)
If it is determined that it is an IC card, it is further checked to see if there is any foreign matter 15 attached to the contact portion 14 (104).

If a foreign object 15 is attached to or damaged on the contact part 14, contact failure will occur if the contact part 14 comes into contact with the conductor 9, so calculate the moving distance in the traveling direction between the contact part 14 and the foreign object 105). , conductor 9 of card 3
Correct the travel distance in the direction of travel up to (106),
Contact between the conductor 9 and foreign matter 15 is avoided. Thereafter, the conductor 9 descends and contacts the contact portions 1 and 4 to read the information on the IC card 3 (109). According to this embodiment, it is possible to determine whether or not the card 3 is an IC card immediately after it is taken into the card processing mechanism 1, and it is also possible to determine whether there is a foreign object 15 on the contact portion 14, which has the effect of preventing poor contact. There is.

Further, a card having an abnormal contact pattern can be ejected from the device or taken into and stored inside the device. The "driving means for discharging the material out of the apparatus or taking it into the apparatus" in claim 2 refers to, for example, a conveyance path including a motor 4 and rollers 5 shown in FIG.

[Effect of the invention] By implementing the present invention, the following effects can be obtained.

Immediately after inserting the card into the device, it can be determined whether it is an IC card or not, so operations such as bringing the IC card into contact with a conductor can be omitted, and transaction processing time can be shortened. In addition, since it is possible to identify in advance whether foreign matter has adhered to the contact portion or the occurrence of scratches, it is possible to determine whether the IC card is a contactable IC card or not, and the conductor of the device will not be contaminated.

In addition, it is possible to make contact while recognizing the location of foreign objects or damaged parts on the contact, preventing contamination of the conductor, and greatly reducing contact failure. It is possible to discharge it out of the device or take it into the device.
