PURPOSE:To provide a system which speedily and precisely identifies a terminal on the system which executes communication between the plural terminals and a processor by means of an infrared ray. CONSTITUTION:The terminals 1 and a light transmitter-receiver 2 transmitting/ receiving data by the infrared ray are provided. The reset pulse of the infrared ray is emitted from the light transmitter-receiver 2, the counters of the plural terminals 1 are reset, the infrared ray is emitted at timing corresponding to a peculiar counter value when the response switch 17 of the terminal 1 is depressed, and the infrared ray identifying the terminal where the response switch 17 is depressed by received timing is used. |
