Abstract

PURPOSE:To attain the accurate positioning and automatic ejection of IC cards with simple constitution by clamping the cards with an elastic bar having a large coefficient of friction. CONSTITUTION:An inserted IC card 1 has contact with a return bar 20 and this bar 20 is shifted together with the card 1. A solenoid is energized after the bar 20 is detected by a photosensor 22, and an arm 13 is moved down with oscillation. Then the card 1 is positioned accurately by an elastic bar 15 having a large coefficient of friction, and the information on the card 1 is read via a contact pin 14. When this reading process is through, the energizatin of the solenoid is released and the arm 13 is reset to its original position. Then the card 1 is ejected automatically by the bar 20 which is moved by a coil spring. Thus the card 1 is positioned accurately and ejected automatically owing to simple constitution needing no control circuit, etc. for a drive motor.

Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an improvement of an IC card reader, and particularly to an IC card reader.
The present invention relates to a card reader clamp and eject device.

[Conventional technology]

the law of nature A conventional device of this kind will be explained with reference to FIG.

When the IC card 1 is inserted from the left in the figure to the position of the photosensor 6 in the direction of the arrow, the motor 3 rotates and the rubber wheel 8 rotates via the worm gears 4 and 5. The IC card 1 is sandwiched between the rubber wheel 8 and the roller 2 by the rotation of the rubber wheel 8, and moves to the stopper 9, and when the photo sensor 7 detects the arrival at the stopper 9, the motor 3 is stopped. After this, the arm 13 is connected to the solenoid 10.
The contact pin 14 comes into contact with a terminal (not shown) of the IC card 1. Finally, when the exchange of information is completed, the suction force of the solenoid 10 is released, the arm 13 is raised by the force of a spring, etc., and the IC card 1 is automatically ejected as the motor 3 rotates in reverse. In the figure, 1
1 and 12 indicate an E-ring and a washer for fixing the arm 13 to the shaft of the solenoid 10.

[Problem that the invention seeks to solve]

By the way, in the above-mentioned conventional IC card league clamping and ejecting device, expensive parts such as a motor and a worm gear are required for traveling and positioning the IC card, and a circuit and power source for the motor are required. Further, there were other problems such as increased power consumption due to the use of the motor.

An object of the present invention is to solve the problems of the prior art, and to provide a clamping and ejecting device for an IC card reader that realizes accurate positioning and automatic ejection of an IC card using an inexpensive and simple mechanism. It is in.

[Means for solving problems]

For this purpose, the present invention provides IC cards in the IC card league.
The feature is that an elastic piece with a large coefficient of friction is used for accurate positioning of the card.

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

1 and 2 are a perspective view and a sectional view showing an embodiment of the IC card reader clamp and eject device according to the present invention, in which 1 is an IC card, 10 is a solenoid, 13 is an arm, and 14 is a contact. The pin, 15 is an elastic piece, 16 is a leaf spring, and 17 is a heath. In FIG. 9, in which the same parts as in FIG. 5 showing the prior art are given the same reference numerals, the arm 13 is constantly receiving an upward force from the leaf spring 16. As shown in the figure, first insert the IC card 1 into the insertion slot of the header 17 (see Figures 1 and 2).
In Figure (a)), the IC card 1 is returned with the return piece 20 on the way.
comes into contact with. When the IC card 1 is further inserted, it moves forward against the coil spring 19, and the photo sensor 22 acts at a position immediately in front of the stopper 10, thereby generating an attractive force in the solenoid 10. When the arm 13 is lowered by the suction force of the solenoid 10, an elastic piece 1 attached to the arm 13 and made of a material with a large coefficient of friction
5 also descends and contacts IC card 1 (Figure 2 (C))
. When the arm 13 further descends, the elastic piece 15
As shown in Figure (C1), the IC card 1 is deflected while applying a component force f1 in the insertion direction and a component force f2 vertically downward, so the IC card 1 is reliably positioned with respect to the reference planes X and Y. As shown in the plan view of Figure 3, if the elastic piece 15 is arranged diagonally rather than parallel to the short side direction of the IC card 1, the elastic side 15 bends during clamping and a component force f3 is generated. Accurate positioning is also performed with respect to the reference plane Z. In FIG. 3, the elastic piece 15 is arranged parallel to the short side of the IC card 1. , y, and z are completed, the contact pin 14 connects to the terminal (
(not shown). When the exchange of information is completed, the suction force of the solenoid 10 is released, and at the same time as the arm 13 is raised, the IC card 1 is automatically ejected by the force of the coil spring 19.

According to the embodiment described above, by using the arm 13 in which the elastic piece 15 having a large coefficient of friction, such as a rubber piece, is disposed, and the return piece 20 including the spring member 19, such as a leaf spring or a coil spring, the conventional device can be improved. motor, worm gear,
It can be replaced with the transmission member attached to these. Further, as shown in FIG. 3, by arranging the brake spring 23, the force of the coil spring 19 can be braked when the IC card 1 is ejected, so that the IC card 1 can be ejected slowly.

〔Effect of the invention〕

As explained above, according to the present invention, by using inexpensive rubber pieces and coil springs in place of expensive parts such as motors and worm gears, it is possible to significantly reduce the cost of products, and Since no circuit or power supply is required, power consumption can be reduced, and the elastic piece with a high coefficient of friction allows the IC card to be clamped for up to 3 seconds.
Accurate positioning with respect to two reference planes is possible, the problems of the prior art described above can be solved, and an IC card reader clamping and ejecting device with excellent functions can be provided.
