Document Type and Number:
Japanese Patent JP3630125
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a sensor unit which can easily and precisely put a condenser lens in focus on the sensor surface of an image pickup sensor.
SOLUTION: The sensor unit comprises an artificial retina sensor 11 as an image pickup sensor for picking up an image of the inner side of a bathroom, a sensor substrate 10 where an infrared sensor, a light emitting element such as an LED, etc., are mounted, and a black light converging member 20 which is mounted on the sensor substrate 10. The light converging member 20 comprises a holder member 21 which is fixed at a specific position of the sensor substrate 10 with screws while covering the artificial retina sensor 11 and a lens barrel 26 which is screwed to a lens barrel fitting part 24 of the holder member 21 and is mounted with the condenser lens 29c, etc., and the condenser lens 29c can easily be put in focus on the sensor surface of the artificial retina sensor 11 by rotating the lens barrel 26 while the holder member 21 is fixed to the sensor substrate 10 with the screws.
