PROBLEM TO BE SOLVED: To provide an operation panel with a minimum function to eliminate operational in convenience and realized inexpensively. SOLUTION: An original platen 21 and an original D are placed on a movable optical unit 20, an original tip position restriction plate 28 is installed on the original platen 21, and the original tip position restriction plate 28 is roughly divided into a touch type operation panel section 29 and a shading correction section 30. The touch type operation panel section 29 has various openings, and each opening is always detected by the mobile optical unit 20 placed beneath the touch type operation panel section 29. Each opening is detected by leading an optical path by the emission of an exposure lamp 22 via the various openings, mirrors 23-25, and a lens to a CCD 27, and then a user shuts the openings by a finger of a user, then the CCD 27 can detect a state of the touch type operation panel section 29 operated by the user. |
