<p>PURPOSE:To attain communication in a wide range between a main body and a card by simple constitution by providing this noncontact type automatic ticket examination machine with a switching means for connecting or disconnecting between an antenna and a transmitter. CONSTITUTION:A central processing unit(CPU) 11 executes arithmetic processing by using a system program stored in a ROM 12 and working data stored in a RAM 13. A door driver 15 for opening/closing repective doors 2a, 2b, a sensor amplifier 16 for inputting and amplifying detection signal from respective human detectors 5a, 5b, a voice driver 17 for executing prescribed guide from a speaker 6, and a transmitter T for transmitting/receiving data to/from a card C are connected to the CPU 11 through an I/O unit 14. The transmitter T receives a radio wave transmitted from the card C through an antenna a1, a2, or arranged in a communication area and a switching circuit S and transmits prescribed data such as the entrance/exiting data of the card C from the main body 1.</p> |
