Abstract
There is provided an edge position detecting apparatus that includes a reflective optical sensor that outputs light to a supporting surface of a supporting member, and receives a reflected light; a moving unit that moves the reflective optical sensor; a reflected light data generating unit that generates reflected light data by obtaining a light-receiving signal; and a detecting unit that detects an edge position of the target detection object. The reflected light data generating unit generates the reflected light data when the target detection object is/is not supported by the supporting member. The detecting unit detects the edge position based on a relative change between a first and a second reflected light data. The first reflected light data is generated when the target detection object is supported by the supporting member. The second reflected light data is generated when the target detection object is not supported by the supporting member.
