Abstract

PURPOSE:To get rid of a multipath reflection based on the glass window of the solid image pickup element, by providing a photodetecting means for detecting a light beam of a white and black density pattern of the original through the glass window, and coating the glass window surface with a multilayer film or a single-layer film in order to prevent a reflection. CONSTITUTION:Both the surfaces of the glass window 7 are coated with the reflection preventive films 18, 18. The specifications of the film 18 are made to conform with the wavelength of an incident light. A light beam 15 only coming from the scanning part of original is made incident to the photodetecting part 16, by making reflected rays from the photodetecting surface 8 transmit, making it escape out of the element, and also preventing a multipath reflection of a light beam coming into the direction except the photodetecting part 16, in the glass window.
