Claims

[Scope of utility model registration request]

An optical sensor consisting of a light emitting part and a light receiving part, a first shielding plate having a plurality of light passing slits attached to a fixed block, and a light passing slit having the same shape as the first shielding plate attached to a movable block. the first and second light shielding plates are arranged to face each other in the optical path width between the light projecting section and the light receiving section, and the first and second light shielding plates A method for detecting slight movement using an optical sensor, characterized in that a change in an output signal of the light receiving section is detected based on a change in the relative position of the light receiving section.
