Abstract
PURPOSE: To prevent unexpected lifting of the original platen, by providing a chamfered part on one side of a transparent original platen, and providing an original platen holding part of hook shape opposedly to this chamfered part.
CONSTITUTION: A glass plate 20 of an original platen 19 has a chamfered part 20a on one side thereof. Along this chamfered part 20a is positioned a glass plate holding part 26b of hook shape provided in the upper part of a guide 26 at a slight gap to the glass plate 20. The upper surface of the holding part 26b is set lower than the upper surface of the glass plate 20. Thus, even if the size of the original mounted on the original platen 19 is large, the original is securely pressed down by the original cover without being folded, and the original is never deviated. Moreover, even if it is attempted to lift the original platen 19 unexpectedly, the chamfered part 20a of the glass plate 20 is securely restrained by the original 26b in the guide 26, so that the glass plate 20 will never be lifted.
