ABSTRACT:
A positioning structure of plane image input apparatus comprises a hollow body, carrying scanned documents and setting a correct picture on outer and inner opposite sides, and an optical module inside the body moving back and forth. The optical module has a correct light source to emit light, a correct hole for reflect light passing through and propagating to the optical module, a guiding mirror set to guide light, and a charge couple device to receive light. The correct light source and the correct hole are respect to the correct picture side of the body. After reflected by the correct picture, light passes the correct hole, to the optical module and is guided by the guiding mirror set to the charge couple device for the optical module to correct color rank and to position. Thus, the positioning structure improves accuracy of correcting color rank and positioning of the correct picture.
