PURPOSE: To permit easy maintenance, inspection, adjusting work, exchanging work, etc. from the top surface side of a copying mechanism by constituting one surface part of the body of a copying machine provided with platen glass in such a way that said part can be opened and closed easily.
CONSTITUTION: The end faces on both sides of a frame body 32 of an original platen are made freely turnable by fixing platen glass 28 on the free end sides of arms 55, 55 via fulcrum pins 54, 54. Spring members 56, 56 such as compression coil springs belleville springs or the like are fitted onto the pins 54, 54, by which the arms 55, 55 are brought into press contact with the side end faces of a frame body 22 of the original platen and the glass 28 can be held in arbitrary turning positions by the friction force of this time. These permit easier maintenance, inspection, adjusting work, exchanging work, etc. than heretofore from the top surface of the copying mechanism.
