The processing operation of the composite card league configured as described above will be described next.

Normally, the card insertion slot 13 is in an open state where the shutter lever 28 moves upward to allow the insertion of a card. When a customer inserts the card 12 into the card insertion slot 13 in this open state, first, the card insertion detection switch SW1 is activated. detects the insertion of the card, and then the tip of the card 12 is inserted into the card passage 18.
The slider 19 is moved forward against the biasing force of the spring 21 until it comes into contact with the slider stopper surface 23 corresponding to the card processing position. When the card is inserted, the card insertion completion detection switch SW2 detects the card insertion completion position, and based on this, the lock solenoid 33 is turned ON, and the shutter lever 28 locks the rear end surface of the inserted card 12. Lock the card.

In conjunction with this locking operation, the upright piece 51 formed on the shutter opening lever 30 tilts to turn the shutter lock detection switch SW3 ON and detect the cartridge locked state. Based on the detection of this locked state, the contacts 25 are brought into contact with the IC contacts of the IC card, and card data reading and writing processing is performed.

When the data processing of this IC card is completed, the lock release solenoid 31 is turned ON to open the card insertion slot 13 and allow the card to be removed.The card insertion detection switch SW1 indicates that the card has been removed. When detected, the IC card transaction ends.

By the way, in the case of a magnetic card, after confirming that the card has reached the insertion completion position with the card insertion completion detection switch SW2, the data on the magnetic stripe is read by the magnetic head 26 during the process of removing the magnetic card. It will be done.

In this case, when removing the magnetic card, the card is pulled out by grasping the front side of the card with the fingertips, so the removal operation can be performed stably without wobbling, resulting in highly reliable magnetic data processing.

In this case, during the opening/closing operation of the shutter lever 28 performed when inserting/removing the card 12, the engaging roller 38 moves each of the shutter open lever 30 and the shutter close lever 32 at an internal engaging portion that switches the opening/closing operation. Since it is switched by rolling into contact with the curved engaging portions 41 and 44, it can be smoothly opened and closed.

In addition, even if the customer continues to hold the rear end of the card 12 during card data processing and an external force is applied to pull out the card, this external force will not directly affect the internal engaging part. The engagement roller 38 smoothly rolls and engages, accurately avoiding an increase in frictional resistance in this area,
Furthermore, on the side of the shutter opening lever 30 that smoothly corresponds to the engagement roller 38, an upright piece 51 formed thereon is provided.
Since the shutter lock detection switch SW3 corresponds to ON and can reliably obtain a lock signal, and corresponds to OFF to obtain a lock release signal, it does not interfere with the internal card lock release operation and can be used at all times. Cards can be taken out stably.

As mentioned above, when opening and closing the shutter lever,
Smooth engagement operation is achieved due to the rolling action of the engagement rollers that avoids drag resistance, so the driving force of the lock release solenoid and lock solenoid that engage and disengage can be set to a small value, making the device more compact and less expensive. Cost reduction can be achieved.

In the correspondence between this invention and the configuration of the above-mentioned embodiment, the opening driving means of this invention corresponds to the unlocking solenoid 31 of the embodiment, and the closing driving means corresponds to the locking solenoid 33 in the same manner. , the roller corresponds to the engagement roller 38, the connecting part of the shutter opening lever corresponds to the L-shaped related platform part 41, the connecting part of the shutter closing lever corresponds to the L-shaped engagement part 44, and the shutter Although the lock detection section corresponds to the upright piece 51, the present invention is not limited to the configuration of the above-described embodiment.
