<p>PURPOSE: To perform an operation both in a contact type and in a noncontact type by passing through and connecting signals from a coil at the time of the occurrence of a first voltage and the signals from a contact field at the time of the occurrence of a second voltage to a chip. CONSTITUTION: An E3 indicates a voltage value when a DC voltage (U) 1 is higher than an input side (E) 1, the voltage value of a member 3 is impressed to an E2 for instance in all the other cases and the output side E3 of the member 2.1.2 is respectively provided with the voltage value 0 when the El and the E2 are at a high level. Thus, the output E3 depends on the member 2.1.2 and the used voltage U1 or N2. The voltage is used as a supply voltage to the member 2.1.2 through a diode D1 (D2) and further through the input side E4 respectively. Thus, the member 2.1.3 constituted as a multiplexer receives clear information relating to future voltage supply. Thus, the operation is performed both in the contact type and in the non-contact type.</p> |
