The IC card is inserted into an IC card reader, which is a device for reading or writing data stored in the memory of the IC card, And a contact terminal for inputting and outputting power and data.

The IC card reader includes a circuit board including a plurality of terminal terminals in electrical contact with the contact terminals of the IC card, and a reader cover as a housing having a guide member for accommodating the IC card.

On the other hand, the IC card reader is generally configured to include a contact switch which is turned on and off according to insertion of a card and applies a control signal to the external device. When the card is inserted in the direction of the insertion portion and pushed to the end position, The control circuit receiving the detection signal from the switch and the 1C module including the integrated circuit chip read the recorded contents.

At this time, when the card is inserted, the clearance due to the tolerance of the card passage is large and the stability due to the clearance is poor. When the card is inserted, the contact switch malfunctions in the off operation in which the card is pushed back by the reaction force of the contact switch. The connector power supply must be performed due to the insertion of the card, but the power supply can not be applied due to a malfunction, and the card information can not be normally read.

Further, since the second outlet 32 is located at the end of the card insertion passage than the first outlet 28, dust or foreign matter can be discharged downward. Furthermore, since the present invention forms the first outlet (28) and the second outlet (32) together with the dust discharging function, it can bring about a significant difference in the effect of dust and foreign matter discharge than the existing reader structure.

8 is a configuration diagram of an IC card reader according to an embodiment of the present invention.

8, the IC card reader 10 according to the embodiment of the present invention includes a connector 12, a control unit 50, a switching unit 52, a data reading unit 53, a data recording unit 54, A memory unit 55 and a power supply unit 56. The switching unit 52 includes a first switching unit 26 and a second switching unit 27. [

The control unit 50 may be configured as a microprocessor for controlling the entire IC card reader as a whole.

Then, the data reading unit 53 performs an operation of reading data from the memory unit.

In addition, the data recording unit 54 can record the read data, and the memory unit 55 can store the recorded data.

When the power is supplied from the power supply unit 56 in accordance with the switching of the switching unit 52 in a state where the connector 12 is in contact with the contact terminal of the IC card and the command from the data reading unit 53 or the data recording unit 54 The data stored in the memory of the IC chip of the card contacted in accordance with the signal is read or written into the memory.

The control unit 50 can detect insertion of the IC card by using at least one of the first switching unit 26 and the second switching unit 27 of the switching unit 52. [

For this, when the IC card is first inserted and contacted by the first switching means 26, the control section 50 determines whether the IC card is normally inserted or not, regardless of whether the second switching means 27 is in contact or not. As shown in FIG. The control unit 50 then reads the data stored in the memory unit 55 in the IC chip through the data reading unit 53 or writes the data to the memory unit 55 in the IC chip through the data writing unit 54 .

On the other hand, if the first switching means 26 is malfunctioning or the IC card is not inserted properly, the control unit 50 can switch the ICs by the second switching means 27 regardless of whether the first switching means 26 is in contact or not. It can be determined that the card is normally inserted. The control unit 50 then reads the data stored in the memory unit 55 in the IC chip through the data reading unit 53 or writes the data to the memory unit 55 in the IC chip through the data writing unit 54 .

As described above, according to the present invention, the normal insertion of the IC card is detected by using at least one of the two switching means (26, 27), so that even if any one of them malfunctions, 12 to perform the on-off operation.

According to the embodiment of the present invention, in order to further improve the contact switching operation by the other switching as described above, the first switching means 26 is arranged as a main switch connected to the circuit block of the connector 12 And the second switching means 27 can be arranged as an auxiliary switch separated from the circuit block of the connector 12.
