Abstract

PURPOSE:To obtain a constant synthetic resistance value not being based on temperature change and to obtain output from a stable integration circuit, by providing a temperature detecting device adjacently to an encoder circuit, and integration circuit, and an OR circuit. CONSTITUTION:When a temperature in the neighborhood of the encoder circuit 1, the integration circuit 2, and the OR circuit 3 changes, the resistance value of a thermistor S1 changes. The resistance value of the thermistor S1 is decreased when the temperature rises, and is increased when it falls. Meanwhile, the resistance values of resistors R1-R3 are increased when the temperature rises and are decreased when it falls. Therefore, it is possible to keep the synthetic resistance value of the resistors R1-R3 and the thermistor S1 constant for the temperature change by inserting the thermistor S1 between the encoder circuit 1 and the integration circuit 2. In such a way, stable output can be obtained in the integration circuit 2.
