Abstract: PROBLEM TO BE SOLVED: To make a photo detector adaptable to various resolutions of a scale slit.
SOLUTION: Two adjacently disposed optical encoder photo detectors adaptable to a scale slit having a reference resolution are paired as one set. A plurality of sets of photo detectors form an assembly. In each set, the output lines of two adjacent division photo diodes are interconnected and the output lines of corresponding division photo diodes between the sets are interconnected to make the two adjacent division photo diodes function like one division photo diode and thus to reduce the resolution of an adapted scale slit to 1/2 the reference resolution. Changing only the wiring is enough to easily and cheaply make the division photo diode adaptable to the scale slit having a resolution, a half of the reference resolution, without changing the shape of the division photo diode.
