PURPOSE:To execute incoming and outgoing processing at a high speed by memorizing various information as a pass with using an electronic means, providing an area, in which the recording of a pass mark with the operation of magnetism, heat and an electric charge, etc., and obtaining function to set the mark at the time of getting-on and to cancel the mark at the time of getting-off. CONSTITUTION:When a passenger comes in, the mark appears on a display surface 3 or the surface 3 goes to be transparent. Then, for an optical signal for check to be given from an external side, a light is transmitted through an electronic pass or the reflection level of the light is changed. For example, a reading signal, which is a high frequency signal, to be received by a receiving coil is counted like a pulse and given to a shift register 15 as a clock signal CK. At a ticket gate, through which the passenger comes in, the high frequency signal and another frequency are simultaneously given and a data signal input is made. When the reading signal and data signal input are simultaneously added, an AND circuit 20 is operated and an output is given to a liquid crystal 22. Then, an entrance record can be shown. When the passenger goes out with using the pass, since the data signal input is not given, a flip-flop circuit 21 is reset and the display of the liquid crystal is returned to a condition before the passenger comes in. |
