Abstract

PURPOSE:To reduce the number of parts, to attain cost down and miniaturization, and to improve reliability by providing a sensor which outputs a signal to decide whether or not a photosensitive body is set at an appropriate position by detecting light reflected from the photosensitive body in the inside. CONSTITUTION:Light emitting elements 121, 122... consisting of plural light emitting diodes are arranged on a line in a frame body whose front plane side is opened, and the sensor 22 for detecting the photosensitive body is arranged at the end part in a longitudinal direction of the frame body. A knob 23 and contacts 24 and 25 are provided at both ends of the frame body, and also, a parting plate 26 is provided between the light emitting diodes 121, 122... and the sensor 22 for detecting the photosensitive body in the frame body, which prevents the direct incidence of the light of the light emitting diodes 121, 122... from being performed. The light emitting diodes 121, 122... perform the static elimination by projecting the light on the photosensitive body, and an interval and a current, etc., to suppress variance in the static elimination as far as possible are set. In such a way, it is possible to reduce the number of parts, to attain the cost down, and to improve the reliability.
