CALL COLLATING DEVICE

Japanese Patent JPH01173194

A

PURPOSE:To inform only a prescribed customer of a call by pairing a card on which a code is recorded with a drilled hole, etc., with a receiver, transmitting a call signal corresponding to the code of the card from a transmitter, and making only the receiver paired with the card detect the call signal. CONSTITUTION:To each receiver, only one switch out of switches 241, 242,..., and 2412 is previously conducted so that each switch for each receiver can be different, and each receiver is set so as to detect only the call signal transmitted by the card corresponding to the receiver. On the other hand, while a reflecting surface is formed at the internal part of an inserting port 2a of each receiver, a light emitting and receiving element is provided for an opposite position to the drilled hole position of the card paired with the receiver. The phototransistor 200 of the light emitting and receiving element is connected to the input side of an LED driving circuit 26. When the card paired with the receiver is inserted into the inserting port 2a, the phototransistor 200 is turned ON, an indicating lamp 2b is lighted, and the coincidence of the collation of the card and the receiver is informed. Thus, the call can be informed only to the prescribed customer, and accurate transactions can be executed.
