感知器。 A light emitting signal that causes a light emitting element to emit light intermittently, and a detection signal that is output when the above light emission is detected by a light receiving element and the received light intensity is above a predetermined level are input, and the detection signal is continuously output for a certain accumulation period. When the output is output, the storage circuit of the storage type photoelectric smoke detector that drives the switching circuit connects a storage capacitor that can be constantly charged via a charging resistor, a discharging means connected in parallel to the storage capacitor, and a constant voltage. It consists of a reference voltage generation circuit that generates a reference voltage, and a switching element that turns on when the terminal voltage of the storage capacitor exceeds the reference voltage and supplies an output to the switching circuit. A storage type photoelectric smoke detector characterized in that a capacitor is discharged for a period from when the light emission signal is output to when the detection signal is output.
