The operation will be described below.

In FIG. 2, when the card is not inserted, that is, the switch 4 is
When the various operation switches are pressed while the switch is not turned on, the processing unit 8 selects the second operation mode and outputs its output to the transmission unit 9
Give to.

When the card 1 is inserted here, that is, the switch 4 is OF
When the switch F is turned ON and the switch 5 is turned OFF, the signal Lo is output for t2 seconds after t1 seconds from the O1 terminal in the processing section 8, and the signal is transmitted to the card detection section 6. In the card detecting section 5, the light emitting elements of the photo interrupters 5a, 5b, 5c in the card detecting section 5 receive the signal and emit infrared light, which is reflected by the bit pattern 2 of the card 1 on the front side.

If the bit pattern on the front surface of each of the photo interrupters 5a, 5b, 5c is white, the reflection amount is large, and if it is black, the reflection amount is small. The reflected infrared light corresponding to each is received by the light receiving elements of the photo interrupters 5a, 5b, 5c, and when the reflected infrared light amount is large, the Lo signal is input, and when the reflected infrared light amount is small, the Hi signal is input terminals i3, i4 of the processing unit 8. Give to i5. After that, the operation mode corresponding to the bit pattern detected by the processing unit 8 is selected,
The operation mode transmission signal is automatically transmitted after t3.

The operation will be described with reference to the timing chart of FIG. 3 and the mode explanatory diagram of FIG.
