Patent number: 5760924Abstract: An original scanning apparatus having a fixed light source which can be applied to image forming apparatus and original reading apparatus. In this apparatus, side reflectors opposed to each other confine light from the light source within a space therebetween in order to efficiently utilize light. A drive assembly for shifting a scanning assembly is arranged to be outside said space between the side reflectors in order to prevent contaminants, oil, or the like of the drive assembly from adhering to reflecting surfaces of the side reflector. Thus nonuniformity in illuminance can be prevented. Also, in order to minimize clearances, which light comes through, between the scanning assembly and the side reflectors, spacers for keeping the clearances constant are provided. Furthermore, in order to prevent nonuniformity in illuminance caused by contaminants, oil, and the like, cleaning members for cleaning the side reflectors are provided.Type: GrantFiled: June 12, 1996Date of Patent: June 2, 1998Assignee: Canon Kabushiki KaishaInventors: Hiroyuki Takahara, Takeshi Aoyama, Yoshimitsu Nakane
