とする光学式センサの調整装置。 In an optical sensor in which a light receiving element detects a light beam emitted from a light emitting element to determine whether the output level of the light receiving element exceeds a threshold value, the amount of light emitted from the light emitting element is determined as "bright". a light emission amount control section that switches between two modes, ie, "bright" and "dark"; a control signal generation section that outputs a control signal to switch the light emission amount control section between the "bright" and "dark"modes; and the light emitting element. and a level down detection unit that compares the light reception level of the light receiving element when the light is emitted in the "dark" state with a reference value and outputs an alarm signal when the level falls below the reference value. The light emission amount in the state is set to a light emission amount that allows the light receiving element to output a level exceeding the threshold value in an unshielded state, and the reference value in the previous level down detection section is set to match the threshold value.
