Abstract

PURPOSE:To operate a start indication switch for image formation without moving an arm which opens and closes an original pressure cover by providing the start indication switch for image formation nearby a handle for opening and closing the original pressure cover. CONSTITUTION:The original pressure cover 3 is supported on an original platen 2 so that it is freely opened and closed. The handle 32 for opening and closing said cover 3 is fitted on the top surface of the cover 2. Then, the start switch 33 for image formation with which the start of image formation is indicated is fitted nearby the handle 32. Consequently, when an operator grips the handle 32 to open the cover 3, sets an original on an original platen 2, and then closes the cover, the operator operates the copy switch 33 without moving the hand from the handle 32 and takes a copy. Consequently, the operation time for the image formation is shortened.
