Description

The present invention relates to an IC card read / write device for reading information stored in an IC card or writing information in the IC card.

Conventional Technology FIG. 4 and FIG. 5 show conventional examples. 4 and 5 show IC
Indicates the card insertion status.

First, the operation sequence will be described. The IC card 1 is inserted through the insertion opening 2a of the main body case 2, the tip of the IC card 1 is applied to the guide portion 3a of the slider 3, and the slider 3 is pushed in. By this operation, the slider 3 contacts the 4a portion of the slider 4, and the slider 4 moves. When the slider 3 is pushed to the end, the slider 4 also moves to the end, and the convex protrusion 3b provided at the end of the slider 3 is sensed by the photosensors 4a and 4b arranged in the main body case 2, and this signal As a result, the solenoid 5 operates, and the hook portion 7a of the lever 7 held by the portion 6a of the slider 6 rotates around the support shaft 8 and the slider 6 held by the spring 9a moves.
When the slider 6 moves, the fixed pin 11 provided on the lever 10 rotates around the support shaft 12, and the cam 13 arranged at the other end of the lever 10 rotates about the support shaft 14 as shown in FIG. When the IC card 1 is moved, the rear end of the IC card 1 is held and the IC card 1 is locked.

When the slider 3 is pushed in, the contact holder 15 mounted on the slider 3 is pressed in the direction of the IC card 1 by the cam portion 2b provided in the main body case 1, and the contact of the contact holder 15 and the IC card 1 The structure is such that the electrodes are in contact.

When the IC card 1 is taken out, the button 17 arranged outside the main body case 2 is pressed, and the lever 17 fixed to the button 16 is detected by the photo sensors 18a and 18b arranged in the main body case 2, ,
The solenoid 5 operates, the cam 13 rotates, the slider 3 and the IC card 1 move toward the insertion slot 2a, and the IC card 1 is ejected.

Problems to be Solved by the Invention As described above, in the configuration according to the conventional example, the mechanism for card locking and card ejection by the solenoid 5 is provided, and a signal detection device for giving to the solenoid 5 is also required, and the consumption of the device is also reduced. There is a problem in that it requires a large amount of electric power, a complicated structure, and it is difficult to supply an economical device.

An object of the present invention is to provide a device that locks an IC card and ejects the IC card by utilizing the insertion force of the IC card without using a solenoid.

Means for Solving the Problems To achieve the above object, the present invention provides at least one slider which is pushed and moved by the tip of the IC card when the IC card is inserted from an insertion slot, and the slider is the IC. A first lever that locks this slider when it moves in the card insertion direction, and at least one second lever that rotates in conjunction with the movement of the slider and locks the rear end of the inserted card. And a contact holding plate holding a contact for making conductive contact with the electrode of the IC card, and rotating or vertically moving the contact holding plate to conduct the contact with the electrode of the IC card. A cam is provided on the slider.

With the above configuration, the IC card can be locked and unlocked by the slider and the first and second levers without using a solenoid, and the contact holding plate can be rotated or moved up and down by a cam provided on the slider to form a contact. IC
Conduction with the electrodes of the card can also be performed.

Embodiment One embodiment of the present invention will be described below with reference to the drawings. First
FIG. 2 and FIG. 2 show a first embodiment of the present invention and show a locked state after the IC card 1 is inserted into the read / write device. FIG. 3 shows a state before the IC card 1 is inserted.
When the IC card 1 is inserted through the IC card insertion opening 31a of the main body panel 31, the L-shaped portion 3 of the first slider 32 is inserted.
The tip of the IC card 1 hits 2a. When the IC card 1 is further inserted from that state, the first slider 32
The support shaft 34 fixed to the slot 33 of the second slider 33
The second slider 33 is also pushed by pushing the right end of FIG. The moving distance of the first slider 32 until the second slider 33 starts to move is determined by the fixed position of the support shaft 34 of the first slider 32 and the length of an elongated hole 33a provided in the second slider 33. . Furthermore I
Although the second slider 33 moves by inserting the C card 1, the lever 36 held by the spring 35
Rotates about the support shaft 37, and the hook portion 3 at one end thereof is moved.
6a locks in the notch of the second slider 33. Further, in this state, the lever 39 connected to the second slider 33 by the support shaft 38 is rotated around the support shaft 40 from the state shown in FIG. 3 as shown in FIG. 1, so that the IC card 1 inserted therein is moved. The rear end is locked. In this state, the IC card 1 is positioned and the IC
The electrodes provided on the card 1 are also positioned. Further, when the above-mentioned first slider 32 is moved by the IC card 1, the cam portion 32 provided on the first slider 32 is provided.
By b, the contact holding plate 43, which is rotatably supported by the support shaft 41 and is provided with the contact 42, is rotationally moved upward as shown in FIG. 2, whereby conduction between the electrode of the IC card 1 and the contact 42 is performed. . Note that 47a is a spring.

When the IC card 1 is ejected from the state shown in FIGS. 1 and 2, the eject button 44 is operated to operate the tip 4 of the button.
The L bent portion 36b at the other end of the lever 36 is pressed by 4a.
Then, the lever 36 is rotationally moved, and the lock of the cutout portion of the first slider 33 by the hook portion 36a of the lever 36 is released, whereby the first slider 33 returns from the state of FIG. 1 to the state of FIG. Then, the lever 39 is also the third
The IC card 1 is rotationally moved to the state shown in the figure, and the IC card 1 is also unlocked. As a result, the restoring force of the spring 45 holding the first slider 32 and the spring 46 holding the second slider 33 causes the IC card 1 to return. The rear end is discharged from the discharge port 31a, and the contact holding plate 43 is also rotated and moved by the spring 47 prior to that, and the contact 42 is separated from the electrode of the IC card 1. In addition, 47 is a flexible pattern film for pulling out a contact, and 48 is a spring for returning a discharge button. Although only one lever 39 is provided in the above embodiment, a plurality of levers 39 may be provided.

As described above, according to the present invention, at least one slider that is pushed and moved by the tip of the IC card when the IC card is inserted from the insertion port and the slider is the I
C a first lever that locks the slider when it moves in the card insertion direction, and at least one second lever that locks the rear end of the inserted card that rotates while interlocking with the movement of the slider. And I
A contact holding plate holding a contact for conducting contact with the electrode of the C card is provided, and a cam for conducting the contact between the contact and the electrode of the IC card is provided on the slider by rotating or vertically moving the contact holding plate. It is provided.

With the above configuration, the IC card can be locked and released by the slider and the first and second levers without using a solenoid, and the contact holding plate can be rotated or moved up and down by the cam provided on the slider. The contact between the contact and the electrode of the IC card can also be conducted.
