Document Type and Number:
Japanese Patent JP7292440
Kind Code:
B2
Abstract:
An automatic door sensor 20 functioning as an optical sensor diagnosis assistance device is provided with a signal acquisition unit 23b and a determination unit 23c and acquires a signal from an optical sensor that receives, by light reception elements 22a provided in a corresponding manner to respective detection segments that are set at specific positions, reflection of light projected from a single light projection element 21a. The signal acquisition unit 23b acquires signals corresponding to the light reception states of the light reception elements 22a provided in a corresponding manner to the respective detection segments. The determination unit 23c determines whether the signals acquired by the signal acquisition unit 23c match each other.
