Abstract
The present invention discloses the construction and manufacturing method of a turning mirror which has a single face or multiple face reflector mirror for scanning laser light in a laser beam printer and the like. The disclosed construction and manufacturing method achieve a low-cost and high-accuracy turning mirror. Photo-setting resin is coated onto the surface of a base mount having a rotating shaft at its center. The surface of the base serves as a substrate for reflector mirror. A glass plate having a good flatness is placed into contact with the resin coating layer. Resin setting light is operated to irradiate the resin coating layer with the peripheral side fringe of the resin coating layer partially or entirely open in order to set the resin coating layer. The glass plate is then separated from the resin coating layer, allowing the flatness of the glass plate to be transferred to the resin coating layer. The turning mirror is then fabricated by attaching a metallic film onto the resin coating layer.
