Abstract

PURPOSE:To simplify the processing of data in an external device and to shorten the processing time of a data processing by prohibiting to transmit by return data information as they are, received through a transmitting line for a receiving, to a transmitting line for a transmitting. CONSTITUTION:A control part 121 of a portable medium processor is connected through transmitting lines L11 and L12 to a personal computer, etc., as a high order device and the data information from the high order device are received through this line L11 for the receiving. Then, the data information are transmitted through the line 12 for the transmitting to the high order device. A transmitting line L13 and a pair of power source lines L4 and L5 are respectively connected to the portable medium of an IC card, etc., various information are sent through the line L13 to the medium and the various information from the medium are received. Inverters 127 and 128 are provided to the respective lines of the lines L11 and L12 and gate circuits IC3 and IC7 and inverters IC4-IC6, etc., are provided to the control part 121. Then, the information received from the transmitting line for the receiving are prohibited to be transmitted to the transmitting line for the transmitting as they are.
