Abstract

PURPOSE:To transmit data without fail by reducing the receiving level of an attenuation signal obtained by a receiving coil while a pulse is sent from a transmitting coil. CONSTITUTION:A binary signal determined by the combination between prescribed positive and negative pulses with a pulse transmitting circuit 22 is sent from a transmitting coil L1. A receiving circuit 23 reduces the level of the attenuation signal obtained by a receiving coil L2 for a fixed time due to the output of a built-in counter. For this reason, the receiving level obtained at the time of sending the pulse can be lowered. Thus, a turning from the circuit 22 around the circuit 23 can be eliminated, and even when the distance between a main body and a data carrier 2 is made larger, the data can be transmitted without fail.
