信号を出力するリトリガブルワンシヨツト回路と
を備えたことを特徴とするスリツト検出回路。 A rotating disk having slits formed in the radial direction on the circumference is interposed between a light emitting element and a light receiving element, and the light emitted from the light emitting element and passing through the slit is received by the light receiving element. The slit detection circuit that detects the slit outputs a signal that becomes H or L for a certain period of time depending on the edge of the signal output from the light emitting unit that causes the light emitting element to emit pulsed light and the light receiving element that receives the pulsed light. A slit detection circuit comprising a retriggerable one shot circuit.
