Abstract
A receiving device includes an optical detector, a first detection region, and a second detection region. The optical detector detects a position of an object of interest to be detected by receiving, with use of one or more of light-receiving portions, reflected light that occurs when light emitted from one or more of light-emitting portions is reflected by the object of interest to be detected. The first detection region is provided at a position closer to the optical detector, and is for detecting movement of the object of interest to be detected with the use of the optical detector. The second detection region is provided at a position farther from the optical detector than the first detection region, and is for detecting presence of the object of interest to be detected with the use of the optical detector.
