BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card application device for card type gate terminals and the like.

[0002]

2. Description of the Related Art In recent years, cards have become widespread in various fields, so-called "card society," and card-type gate terminals (automatic ticket gates) mentioned above as an example of card-applied equipment are used in leisure facilities. Widely used. This card type gate terminal manages the entrance and exit of users with a magnetic card, and a general configuration conventionally implemented is shown in FIGS. In the figure, 1 is a gate terminal installed in a gate passage 2 of the facility, 3 is a gate door installed at the passage exit side of the gate terminal 1, 4 is a card insertion slot, 5 is a card return slot, and a card insertion slot 4 A card reader / writer 7 combined with a card transport mechanism 6 is incorporated in the machine between the card return port 5 and a gate controller (not shown). Reference numeral 8 is a card shutter mechanism provided in the latter stage of the card insertion slot 4.

The function of such a card type gate terminal is well known, and when a visitor inserts a card 9 (a magnetic card, in which necessary data is encoded in advance) into the card insertion slot 4, the card 9 is read / read. After being drawn into the writer 7 to read and write the card data, it is automatically conveyed to the card return port 5 by the card conveying mechanism 6, and in the process, the card data is collated to determine its suitability. When the card 9 is determined to be appropriate, the visitors can pass through the gate terminal while the gate door 3 remains open. On the other hand, when the card 9 is determined to be inappropriate, the gate door 3 is closed to prevent entry.

[0004]

By the way, the above card application equipment such as the card type gate terminal has the following problems in use. That is, as is well known, the card 9 carried by a visitor is a resin card provided with a stripe-shaped magnetic data storage unit, and static electricity is often charged during carrying. On the other hand, the card reader / writer 7 built in the gate terminal 1 is equipped with a magnetic head for scanning the storage portion of the card 9 and an electronic circuit for controlling the magnetic head. Therefore, normal card read /
Although the writer is provided with an electrostatic shield to prevent static electricity from flying in from the outside, if the card 9 inserted in the card insertion slot 4 of the gate terminal is charged with static electricity, the card 9 When the read / writer 7 is pulled in, static electricity is discharged, which may become noise and cause various troubles such as a data processing error.

The present invention has been made in view of the above points, and an object of the present invention is to solve the above-mentioned problems and to take measures against static electricity so that the equipment does not malfunction due to static electricity carried in by the card itself. To provide.

[0006]

In order to achieve the above object, according to the present invention, static electricity charged on the card is charged in the card passage between the card insertion slot and the card data processing device on the subsequent stage. A means for removing static electricity shall be provided. Here, as the static electricity removing means, it is possible to implement by providing a grounding electrode which projects the tip of the electrode into the card passage and makes contact with the card passing therethrough, or a static elimination brush. The size of the card passage regulated by the ground electrode is preferably set corresponding to the thickness of one card.

[0007]

According to the above construction, the card inserted into the card insertion slot is connected to the ground electrode provided in the card passage before being pulled into the card data processing device (card reader or card reader / writer) in the subsequent stage. Or contact with a static elimination brush (a brush made of conductive soft fiber is laid along the slit-shaped window that opens in the metal frame and serves as a card passage), and the static electricity charged on the card here Is discharged to the ground side through the ground electrode and static elimination brush, and is removed from the card. Therefore, the card enters the card data processing device in a state where it is not charged with static electricity, thereby reliably avoiding the occurrence of trouble in the electronic circuit caused by static electricity. In this case, if the dimension of the card passage regulated by the ground electrode is set to correspond to the thickness of one card, it is possible to prevent a transport trouble in which the two cards accidentally pass through the card passage while overlapping each other.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In the drawings of each embodiment, the same parts as those in FIG. 4 are designated by the same reference numerals. Example 1 is a configuration diagram of an example corresponding to FIG. 1 and claims 2 and 3 of the present invention. In this embodiment, the card shutter mechanism 8 arranged between the card insertion port 4 and the card lead / writer 7 is provided with a ground electrode 11 and a ball 12 which also serve as static electricity removing means also as a dimension restricting member for the card passage.
However, they are assembled so as to face each other with the card passage 10 interposed therebetween. Reference numeral 8a is a shutter plate, and 8b is a drive mechanism for the shutter plate.

Here, the ground electrode 11 is a metal bolt of good conductivity screwed into the block of the shutter mechanism 8, the tip of which is attached so as to project toward the card passage 10, and the ground electrode 11 is provided. The ground wire 13 drawn out from is grounded to the ground on the ground side through the metal outer frame of the card type gate terminal. Also, the ball 12 is stored by being dropped into a recess on the lower side of the passage so that the end surface thereof slightly protrudes from the card passage 10.
The distance d between the tip of the ground electrode 11 and the ball 12 is set in the range of t ≦ d <2t, where t is the thickness of the card 9, and the two cards are erroneously overlapped at the same time and the card passage The dimensions are controlled so as to prevent passing through 10.

With this structure, the card 9 is inserted into the card insertion slot 4.
When the card is inserted, the card 9 comes into contact with the ground electrode 11 in the process of passing through the card passage 10 of the shutter mechanism 8 and is then drawn into the card read / writer 7 in the subsequent stage. Therefore, the static electricity charged on the card 9 is discharged to the ground side through the ground electrode 11 and the ground wire 13 on the front side of the card lead / writer 7, and the static electricity is removed from the card 9. As a result, static electricity is not directly brought into the card reader / writer 7 by the card 9, and various troubles caused by static electricity can be prevented.

The card 9 passing through the card passage 10
Even if a slight gap remains between the ground electrode 11 and the ground electrode 11 without a good contact therebetween, the high-voltage static electricity charged on the card 9 will pass through the micro gap to the ground electrode 11
However, in order to make the contact between the card 9 and the ground electrode 11 more reliable, for example, the ball 12 is spring-biased upward or the discharge electrode is shoeed. As a structure, it is preferable to take measures such as downward biasing of the spring.
