A further object of the invention is to provide means Where by the exposing mechanism is automatically locked when the last plate has been shifted and exposed. in order to bring this fact to the attention of the operator and to prevent an inadvertent second exposure of the last plate, it being contemplated in the preferred form or the invention that the exposing and shifting functions be embodied in one element and the shunting and locking functions to these and other in certain combinations of parts.
