Abstract
PURPOSE:To achieve the detection of the direction of revolution and the amount of revolution of a large-sized gear to which an actuator is connected, by taking a signal for control of a counter circuit and a motor driving circuit as the same signal. CONSTITUTION:When an instruction for forward revolution of a motor 1 is given to a central processing circuit 5b, the circuit 5b transmits a reset signal to a reset terminal R of a counter 5a to zero the count value. A signal of H level is outputted from a unidirectional output terminal DIR, the instruction of addition is made to a up/down terminal of the circuit 5a, and this signal of H level is a forward instruction signal to a motor driving circuit 6. At the same time, the operation instruction signal of H level is transmitted from an operation output terminal IO to the circuit 6. When the motor 1 starts forward run with both the instruction signals, a large-size gear 3 rotates, and passing/nonpassing of light is repetitive to a phototransistor TR1 of a light emitting diode D1. Thus, the circuit 5a counts the number of pulses proportional to the amount of revolutions of the large-size gear 3.
