Abstract
A printing apparatus includes a paper cutter, a hole puncher and a guide clip which engages a strip of printed paper for conveyance to a developer. As the printer operates intermittently while the developer operates continuously, a reservoir or buffer zone is provided for the paper between the two. A mechanism for storing guide clips automatically delivers and orients a guide clip so as to engage a transported paper strip for further conveyance therewith by means of a chain conveyor or the like. As the printer may move vertically independently of the fixed developer, the conveyor is made expandible so as to accommodate differences in the conveyance distance.
