A discharging mechanism for automatically discharging 4 is provided. Note that the expensive ones are also provided with an automatic insertion mechanism.

By the way, the gate device in which this reader / writer is used is provided with a mechanical opening / closing mechanism (gate) that permits or prohibits passage of people. Usually, the reader / writer needs to be installed in a place avoiding this opening / closing mechanism and not to be noticeable. Further, since the reader / writer only accesses the IC card 84 to read and write information and transmits the information to the gate device, the reader / writer main body 80 itself has the IC card 84.
It should be small as well.

[0006]

However, in the above-mentioned conventional reader / writer, since it is necessary to completely accommodate the IC card main body, the reader / writer main body can be made thin so that its width is at least less than the lateral width of the IC card. Therefore, there was a problem that miniaturization could not be achieved.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a reader / writer capable of downsizing the reader / writer.

[0008]

In order to achieve the above-mentioned object, the reader / writer of the present invention is provided with a rectangular IC card having a contact portion at a predetermined position on the card surface in an oblique direction and in the main body of the IC card. An insertion port that can be inserted in a range larger than a diagonal line and is inserted with the end portion of the IC card projecting in an oblique direction, and the IC card inserted in the insertion port are provided in two diagonal directions. Supporting means supported by the edge portion, biasing means for biasing the IC card supported by the supporting means in a direction of ejecting from the insertion slot, and the contact portion of the IC card supported by the supporting means. And a contact portion provided corresponding to.

The locking means of the reader / writer is the IC described above.
This is a movable locking claw that unlocks the edge of the IC card by a control signal output when the processing of the card is completed.

[0011]

According to the present invention, when the IC card is obliquely inserted into the insertion slot, the supporting means is projected to support the IC card when two diagonal edges of the IC card are hidden in the insertion slot. After accessing the card, the support means unlocks the edge of the IC card.

Therefore, the IC card can be supported in a state of protruding from the reader / writer main body, and the width of the reader / writer main body is set to the IC while taking measures to remove the IC card.
It can be thinner than the width of the card.

As a result, the size of the reader / writer can be reduced.
