Title:
赤外線温度センサ、及び、それを用いた定着器
Document Type and Number:
Japanese Patent JP5207329
Kind Code:
B1
Abstract:
To provide an infrared temperature sensor which can accurately measure a surface temperature of an object to be detected even under a severe temperature detection environment. An infrared temperature sensor including: a sensor case 10 including a first airspace 53 (a light guiding region) that guides infrared rays entering from an infrared entrance window 26, and a second airspace (a light shielding region) that is adjacent to the light guiding region via a partition wall 52, and where an upper wall 24 that blocks entrance of the infrared rays is formed on an entrance side of the infrared rays; a film 40 that absorbs the infrared rays reaching the film through the light guiding region, and converts the infrared rays to heat; a sensor cover 30 that is arranged opposing the sensor case 20 via the film 40; an infrared detection element 43 and a temperature compensation element 45 arranged on the film 40, wherein the light guiding region and the light shielding region have substantially symmetrical forms with respect to the partition wall 52.
