DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a 10-card read/write device.

2. Description of the Related Art It is known that an IC card reader/writer has a locking claw on the front side of the card reader in order to prevent the card from being viewed while the card is being read or written. As a holding method, conventionally, for example, JP-A-61-
As described in Publication No. 16384, when the IC card has been inserted, the lock claw is lowered and brought into contact with the rear end of the IC card, thereby completely preventing ejection of the IC card due to the biasing force applied to the IC card. A method is used in which the IC card is held in a read/write position.

Problems to be Solved by the Invention Conventional IC card readers/writers apply a force in the ejection force direction to the IC card held in the reading/writing position as described above, so it takes a large amount of effort to release the lock claw. A release force is required, and the power consumption of the solenoid used for release is large.

Means for Solving the Problems The present invention moves in contact with the tip of an IC card, and
a sliding lever that applies elastic bias to the C card in the ejection direction;
a lock pawl that operates in conjunction with the movement of the sliding lever;
a contact block that rotates in contact with the sliding lever; a sliding lever restraining means that restrains movement of the sliding lever;
It consists of a detection means that detects that the IC card is in the read/write position, and when the IC card is inserted, the
When the sliding lever moves backward due to the insertion force of the C card and the lock claw is lowered, the contact block rotates and the contact pin on the contact block is pressed against the IC card terminal surface, the detection is performed. The means detects that the IC card has been inserted to the read/write position, and fully operates the sliding lever restraining means in response to an external signal to restrain the sliding lever from moving. The IC card is held between the card abutting part and the lock claw, and when the card is ejected, the sliding lever restraining means is fully released by an external signal and the card is completely ejected by elastic biasing. It is something.

Operation In the IC card reader/writer according to the present invention, when an IC card is inserted, the tip of the ICi card contacts the sliding lever abutting portion, and the sliding lever, which is elastically biased in the ejection direction, is moved rearward by the insertion force of the IC card. move it. In conjunction with the movement of the sliding lever, the lock claw is lowered and all the contacts are brought into contact with the terminal surfaces of the IC card.

At this time, the detection means fully detects that the IC card is in the read/write position, and the sliding lever locking means is activated by an external signal to fully lock the sliding lever. The IC card is held between the abutting part of the sliding lever (-) and the lowered lock claw.At this time, the elastic bias applied to the IC card in the ejection direction due to the restraining of the sliding lever is When the IC card is ejected, the sliding lever restraining means is released by an external signal, and the IC card is again elastically biased in the ejecting direction from the sliding lever, and the IC card reader and the IC card are moved together with the sliding lever. It moves to the front of the lighter and is ejected.In conjunction with the movement of the sliding lever, the lock pawl is raised and the contact is removed.

Further, a sliding lever 12 is attached to a bottle 11 fixed to the main body 2 through a long hole, and the sliding lever 12 moves in the card insertion direction. The sliding lever 12 has a return spring 13
It has an elastic bias in the ejection direction. The sliding lever 12 is connected to the lock pawl 7 via a connecting lever (a) 14 and a connecting lever (b) 15e, and the lock pawl 7 is operated in conjunction with the movement of the sliding lever 12. A stopper lever 16 is similarly attached to the bottle 11 via an elongated hole so as to overlap the slide lever 12. The sliding lever 12 and the stopper lever 16 are connected via a lever spring 1.
Further, the lever abuts at the lever abutting portion 18 .

The stopper lever 16 has a locking portion 19 and is locked by a locking pawl 21 of the latch lever 2o. Latch lever 20
is driven by the solenoid 22.

In this state, insert the IC card from the card insertion slot 3 with the terminal side facing up. The front sensor lever 6 rotates and enters the shielding position of the front photosensor 23 to detect the insertion of the card, and the magnetic head 5 detects a on the IC card.
Start reading the stripe. After reading the magnetic data, when the card is inserted to the position where the EB head 5 removes the card, the leading edge of the card touches the sliding lever 1.
The card contact portion 24 of No. 2 is contacted. When the sliding lever 12'i is moved to the rear of the IC card league/writer by the insertion force of the IC card, the lock claw 7 descends in conjunction with the movement of the sliding lever 12, and the contact block 10 is pushed by the sliding lever. Rotate. Stopper lever 16 is lever spring 1
