1. An optical detecting device comprising:
- an emission unit that emits emitting light;
a light-receiving unit that receives the emitting light reflected off an object;
an amplifying unit that amplifies a received-light detection signal of the light-receiving unit;
a detecting unit that outputs position identifying information of the object based on an amplified signal output from the amplifying unit;
a determining unit that determines a position of the object based on the position identifying information; and
a coupling capacitor provided between an output node of the amplifying unit and an input node of the detecting unit.
