Claims

[Scope of utility model registration request]

A plurality of photointerrupters are arranged in one or more rows, and each photointerrupter row is provided with a light-shielding plate that moves in the row direction, and a plurality of edges formed by the light-shielding plate adjust the proportion of the photointerrupter. A position detector in which the spacing between photo-interrupters, or the spacing between photo-interrupters and the edge spacing of a light-shielding plate are set so that areas are sequentially and continuously passed through.
