Claims

[Scope of utility model registration request]

A first sensing head that includes a light receiving element and a light emitting element and has a color filter attached to its front surface, and a second sensing head that includes a light receiving element and a light emitting element and has a color filter of a different color than the above-mentioned color filter arranged on its front surface. Colored vertical lines and colored horizontal lines corresponding to the coloring of the color filters are attached perpendicularly to a code plate mounted on the housing and disposed opposite to the sensing head, so that the colored vertical lines and A position detection device that measures the amount of movement by detecting the number of times a colored horizontal line crosses with each light receiving element.
