Abstract

PURPOSE:To reduce influence exerting upon the output of an infrared detector of a shutter temp., by intermittently interrupting infrared rays by a shutter constituted of a material with infrared emissivity epsilon of 0.2 or less. CONSTITUTION:A shutter 2b is constituted of a material with infrared emissivity epsilon of 0.2 or less such as an iron plate, an SUS polished plate or an aluminum plate and driven by a motor 3 and intermittently interrupts infrared ray input R from an object to a pyroelectric type infrared detector 1. A thermistor 5 is provided in the vicinity of the infrared detector 1 and used as an atmospheric temp. detector.
