JPH0367382A - Preventing device for mixture of foreign matter on magnetic card travel path - Google Patents

Abstract

PURPOSE:To remove the foreign matter from the device before it is taken in the magnetic card travel path and to prevent trouble from occurring by providing a couple of sensors which detect the foreign matter which is ejected by a roller with a brush and is deformed. CONSTITUTION:Foreign bodies 5a and 5b sticking on the surfaces of the magnetic card 3 are taken in by rollers 2a and 2b and ejected by a couple of rollers 4a and 4b with brushes which rotate in contact in the opposite directions from the taking-in directions to be deformed in swell shapes. The card 3 itself passes against the ejecting operation the rollers 4a and 4b and is taken in the specific card travel path. The foreign matter detection sensors 6a and 6b are provided almost at right angles to the taking-in direction of the card and output detection signal when the foreign bodies in the swell shapes are present and a control part 7 controls the reversing of the rollers 2a and 2b to eject the card 3 in process of the taking-in operation from an insertion slit 1 together with the foreign bodies 5a and 5b.

Description

[Detailed Description of the Invention] [Summary] This invention relates to a magnetic card reading device, and in particular to a device for preventing foreign matter from entering a magnetic card running path, by detecting a foreign matter such as a piece of paper inserted into a magnetic card insertion slot along with a magnetic card. In order to provide a device that eliminates this problem, we have developed a pair of take-in rollers installed in a magnetic card insertion slot, and a pair of brushes that rotate in contact with both sides of the magnetic card taken in by the take-in rollers in a direction opposite to the take-in direction. A brushed roller, a pair of foreign matter detection sensors that detect foreign matter that has been deformed by being removed by the brushed roller, and a control section that drives the take-in roller in reverse based on the output of the foreign matter detection sensor.

[Industrial application field]

The present invention relates to a magnetic card reading device built into an automatic deposit dispensing device or the like, and particularly to a device for preventing foreign matter from entering a magnetic card running path.

[Conventional technology]

Conventionally, when an unacceptable magnetic card is accidentally inserted into the magnetic card slot of an automatic deposit payment device, etc., the device imports the card into the device and determines whether it is correct or not. It has a function to immediately return the card to the magnetic card slot.

[Problem to be solved by the invention]

If a foreign object such as paper or a receipt is inserted into the magnetic card slot on top of a legitimate magnetic card, the device will not be equipped with a detection function to detect this foreign object, so it will be taken into the magnetic card transport path. . Thereafter, the foreign object separates from the magnetic card as it passes through the reading process, etc. of the loaded magnetic card, and the device detects the separated foreign object, treating it as a magnetic card on the road. The magnetic card simultaneously detects an abnormality that exists in the magnetic card running path,
There is a problem in that the equipment is considered to be malfunctioning and its operation is stopped.

[Means to solve the problem]

FIG. 1 shows a block diagram of essential parts of the present invention. A pair of take-in rollers 2a and 2b provided in the magnetic card insertion slot l, and a pair of brushed rollers 4a that rotate in contact with both sides of the magnetic card 3 taken in by the take-in rollers 2a and 2b in a direction opposite to the take-in direction. , 4b, and foreign objects 5a, 5b that have been removed and deformed by the brushed rollers 4a, 4b.
The apparatus includes a pair of foreign object detection sensors 6a and 6b for detecting foreign object detection sensors 6a and 6b, and a control section 7 that drives the take-in rollers 2a and 2b in the reverse direction based on the outputs of the foreign object detection sensors 6a and 6b.

[For production]

Foreign objects (for example pieces of paper) 5a and 5b attached to one or both sides of the magnetic card 3 pass through the magnetic card insertion slot,
The foreign matter 5a, 5b attached to the magnetic card 3 is taken in by the taking-in rollers 2a, 2b in the taking-in direction of the magnetic card 3, and is removed by a pair of brushed rollers 4a, 4b which contact and rotate in the opposite direction to the taking-in direction. It deforms into a swollen state as shown in the figure. On the other hand, the magnetic card 3 itself has a pair of brushed rollers 4a.

The magnetic card passes through against the removal action of the magnetic card 4b and is taken into a predetermined magnetic card running path. Foreign object detection sensor 6a.

6b is provided in a direction substantially perpendicular to the direction in which the magnetic card is taken in, and when it detects the presence of a foreign object deformed into a bulging state, it outputs a detection signal, and in response to the detection signal, the control unit 7 controls the taking-in rollers 2a and 2b in reverse. , the magnetic card 3 that was being taken in is removed from the magnetic card insertion slot 1 together with foreign objects 5a and 5b.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a block diagram of essential parts of the present invention. In the figure, 1 is a magnetic card insertion slot provided on the front panel of an automatic deposit payment device, etc., and 2a and 2b are a pair of magnetic card slots 2a and 2b for taking a magnetic card 3 inserted from the magnetic card slot 1 into a predetermined magnetic card running path. 3 indicates a magnetic card.

Reference numerals 4a and 4b denote a pair of brushed rollers that rotate in contact with each other in a direction opposite to the taking-in direction, and the taking-in roller 2a resists the contact rotation of the brushes to eliminate the contact rotation.

The magnetic card 3 driven by the roller 2b has a brushed roller 4a.

It is assumed that a brush is installed that is strong enough to pass between the foreign objects 4b in the intake direction (direction of arrow A) without being damaged, but to remove foreign objects 4a and 4b, which will be described later, in the direction of arrow B.

5a and 5b are foreign objects (for example, pieces of paper, receipts, etc.) attached to the magnetic card 3 through static electricity or oil or fat;
Reference numerals 6a and 6b denote a pair of foreign object detection sensors, which are provided in a direction substantially perpendicular to the direction in which the magnetic card is taken in, and have a function of detecting the presence of foreign objects 5a and 5b that have been deformed into a bulging state by the brushed rollers 4a and 4b. However, for example, a photo inkter or the like in which a light-emitting element and a light-receiving element are arranged facing each other is used.

Reference numeral 7 denotes a control unit including a pair of foreign object detection sensors 6a.

By receiving one or both outputs of the magnetic card 6b, the take-in rollers 2a and 2b are reversely controlled, and the magnetic card 3 that was in the middle of being taken is removed from the foreign object 5a r5.
It has a function of removing the magnetic card from the magnetic card insertion slot 1 together with b.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, foreign objects that adhere to the magnetic card 3 and are inserted are removed from the device before they are taken into the magnetic card running path, which is effective in preventing the occurrence of malfunctions. be.
