摘要:
An image position detector includes a light emitting element to emit light to an image on an image carrier, a first light receiving element to receive a specular reflection of light from a surface of the image carrier and output a first light receiving signal, and a second light receiving element to receive a diffuse reflection of light from a surface of the image and output a second light receiving signal. The image position detector is configured to find the end position of the image according to a multiplied value obtained by multiplying values of the first and second light receiving signals by a constant coefficient.

A photosensor includes a light emitting element to emit light to a target object, a light receiving element to receive the light emitted from the light emitting element and reflected by the target object, and a circuit board on which the light emitting element and the light receiving element are mounted, including at least one protrusion thereon. The light emitting element and the light receiving element each have a terminal. The at least one protrusion is configured to support one of the light emitting element and the light receiving element in a contact manner in a state that the terminal is electrically connected to the circuit board.
