Description

Description: TECHNICAL FIELD The present invention relates to an IC card reader.

Conventional technology Conventional IC card readers use a card insertion force to force the contact pins into contact with the card and prevent the card from being pulled out during access to the IC card. The lock claw was lowered and the card was held.

Problems to be Solved by the Invention As described above, in the conventional IC card reader, even when a magnetic card that does not need to be locked is inserted, the lock claw is lowered at the end of card insertion and the card is held, so that it is magnetic only. However, there is a problem that the card cannot be pulled out immediately after the card is inserted as in the case of a manual card reader of the insertion / pull-out type, and the operation of inserting / pulling out a magnetic card without an IC is not smooth.

Means for Solving the Problems To solve the above problems, an IC card reader of the present invention is arranged such that a connector pin is brought into contact with an IC terminal surface of the card when a card is inserted, and the connector pin is connected to the IC of the card when the card is ejected. A connector contacting / separating means for detaching from the terminal surface, and a locking claw when it is determined that the inserted card is an IC card based on the presence or absence of a response from the connector pin contacted with the IC terminal surface of the card or the content of the response. And lock means for preventing the card from being removed by operating the card.

The IC card reader according to the present invention, after the card is inserted,
When it is determined that the card is an IC card based on whether or not there is a response from the card to access to the IC of the card by the connector pin contacted with the card, the locking means is operated. When a magnetic card having no IC such as a credit card is inserted, the locking means does not operate, so that the card can be pulled out after the card insertion is completed. Further, when the IC card is inserted, the locking means is operated after the card insertion is completed, thereby preventing the card from being pulled out while accessing the IC of the card.

Embodiment An embodiment according to the present invention will be described below with reference to the drawings.

A second coil spring 20 and a solenoid 21 are attached to one end of the L-shaped lever 17, and a small lever 22 and a guide spring 23 are attached to the other end of the L-shaped lever 17 so as to be rotatable about the first pin 24. The small lever 22 has the second pin 25 and the guide spring 23
Pinches the second pin 25 and the third pin 26 set under the chassis 16. The rotation lever 18 is connected to a lock claw 28 via a connection lever 27. A third coil spring 29 is attached to the connection lever 27, and biases the lock claw 28 in the upward direction. A fourth coil spring 30 is attached to the latch lever 19 and biases the latch claw 31 so as to abut the latch groove 32 of the rotating lever 18. A third micro switch 33 is arranged on the rotation lever 18, and detects that the lock claw 28 has been lowered by the claw portion 34 of the rotation lever 18 pressing the third micro switch 33.

In such a configuration, a card is inserted from the card insertion slot 2. When the card is inserted, the front sensor lever 4 rotates and presses the first micro switch 5 to detect the insertion of the card, and the magnetic head 3 reads a magnetic recording signal of a magnetic track of the card. The card comes into contact with the moving element 7 to move the moving element 7 backward. With the movement of the mover 7, the second contact member 11 rotates while abutting on the hole 35 of the main body 1 to lower the rear part of the first contact member 10 on the card surface, and the front part of the first contact member 10 also moves. The contact pin 36 of the IC connector 9 attached to the first contact member 10 is pressed against the IC terminal surface of the card by descending to the card surface along the elongated hole 12. The card is held between the card holders 15 near the insertion end position. When the rear end of the movable element 7 presses the second micro switch 6, the end of the card insertion is detected. At this time, when it is determined from the magnetic recording signal read by the magnetic head 3 that the inserted card is an IC card, the solenoid 21 is excited and the L-shaped lever 17 is turned on.
pull. The L-shaped lever 17 rotates in the direction of arrow A in FIG. 2 (a), and the second pin 25 on the small lever 22 is guided by the guide spring 23 and moves. The rotating lever 18 is rotated in the direction of arrow B by contact, and the lock claw 28 is lowered. As shown in FIG. 2 (b), the rotation of the rotation lever 18 causes the latch claw 31 of the latch lever 19 to fall into the locking portion 38 of the latch groove 32, thereby restraining the movement of the rotation lever 18. At this time, it is detected that the claw portion 34 of the rotating lever 18 presses the third micro switch 33 and the lock claw 28 is lowered. solenoid
After the excitation of 21, the L-shaped lever 17 is retracted by the second coil spring 20 in the direction of arrow C in FIG. 2B, and the second pin 25 on the small lever 22 is returned to the original position by the guide spring 23. . After reading and writing of data from the IC of the card, the solenoid 21 is excited again by a signal from the computer, and

, The latch lever 19 is rotated in the direction of arrow D in FIG. 2 (c), and the latch claw 31 is released from the locking portion 38 of the latch groove 32. The rotation lever 18 returns to the original position by the bias of the third spring 29, and the lock claw 28 is raised. When the card is pulled out, the moving element 7 moves in the discharging direction by the first coil spring 8 and
The contact member rises from the card surface, and the contact pin 36 of the IC connector 9 pressed against the card terminal surface is separated. The rear end of the mover 7 is separated from the second microswitch 6,
When the start of ejection of the card is detected, the reading of data of the magnetic track of the card by the magnetic head 3 is started. When the card is completely ejected, the sensor lever 4 returns and the first micro switch 5 is released. When it is determined from the magnetic recording signal read by the magnetic head 3 when the card is inserted that the inserted card is a magnetic card having no IC, the solenoid 21 is not excited and the lock claw is not lowered. After the insertion is completed, the card can be pulled out immediately, the rear end of the movable element 7 is separated from the second micro switch 6, and when the start of ejection of the card is detected, the magnetic head 3 reads the magnetic recording signal of the magnetic track at the time of ejection of the card. Is performed.

As described above, the embodiment in which the card is judged to be an IC card based on the magnetic recording signal of the card read by the magnetic head when the card is inserted and the lock claw is lowered is described. When the lock claw is lowered by determining that the card is an IC card based on the response to the access, the same operation is performed.

Effect of the Invention As described above, according to the present invention, when a lock for preventing card removal is not required, such as when a magnetic card such as a credit card is inserted, the lock means is not operated so that the lock is not performed. Since the inserted card can be removed as it is without lowering the claws, the operation of inserting and ejecting a magnetic card having no IC becomes smooth.
