Abstract
A chain drive arrangement is disclosed for movably driving an exposure carriage of a photocopying machine. The chain drive includes an endless chain running over two spaced apart chain gears. A carrying pin is arranged on the chain which engages into a connecting link slot transversely to the travel direction of the chain. The connecting link slot is arranged at a carrying lever of the exposure carriage. In order to accommodate movement of the exposure carriage to an intermediate or neutral position so it can be removed independently of the position in which the driving mechanism is stopped, a readily manually detachable connection is provided between the carrying pin and the carrying lever. A leaf spring hingedly connects the carrying lever to the exposure carriage and biases the lever to a connection with the carrying pin. Manual pressure against an upwardly protruding gripping flange of the lever operates against the leaf spring force to disengage the lever slot and carrying pin so the carriage can be removed.
