Abstract
A copying machine of the scanning exposure type includes an original receptacle or an optical system which is adapted to reciprocate. The original receptacle or optical system is mounted on a rockable support which has one end pivotally mounted on the body of the copying machine. A normally inoperative locking device is interposed between the original receptacle or optical system and its drive mechanism, so that when the rockable support is released and pivoted, the locking device is effective to prevent a movement of the original receptacle or optical system which may result from its weight.
