Abstract
A guide apparatus for guiding a movable contact glass, which serves as an original table in an electrophotographic copying machine, to a predetermined exposure position for slit exposure, without any inclination of the contact glass, comprising a drive member for reciprocating the contact glass in the exposure scanning direction and a guide member, which is shorter than the distance from the exposure position to the center of gravity of the contact glass at completion of the exposure scanning and whose upper surface at the exposure position is higher than the other upper surface thereof. The drive apparatus comprises a loop drive transmission member which is rotated in one direction and which substantially reciprocates the contact glass and can have a lock release apparatus capable of making the contact glass movable manually when the contact glass is stopped at its dead point.
