Abstract

PURPOSE:To attain miniaturization and low power consumption by incorporating a Schmitt trigger circuit, counting circuit and count display driving circuit in the same chip. CONSTITUTION:Output 11 from a photodetector is inputted to operational amplifier 20 and then converted into a rectangular wave at a threshold voltage set by resistance 15, 16 and 17, and the wave is waveform-shaped by chattering preventing circuit 18 and supplied to a counting circuit. Transistor 14, on the other hand, functions to reduce the electric power. A Schmitt trigger circuit, counting circuit and count display driving circuit are incorporated in the same chip.
