Claims

[Scope of utility model registration request]

In an optical sensor in which a light receiving element detects a light beam emitted from a light emitting element and determining whether an output level of the light receiving element exceeds a threshold value, the light emitting amount is switched. a control section; a control signal generation section that supplies a plurality of control signals to the light emission amount control section for switching the light emission level of the light emitting element; and a control signal generation section that detects the light beam emitted from the light emitting element and converts it into an electrical signal. a light-receiving element, an amplifier that amplifies an output signal of the light-receiving element, and an amplifier control unit that controls an amplification factor of the amplifier;
When a plurality of control signals are output from the control signal generation section, the relative relationship between the signals output from the amplifier is calculated, and the calculation result is compared with a reference value, and the calculation result is made to match the reference value. 1. An optical sensor adjustment device comprising: an amplification factor determining section that operates an amplifier control section.
