ABSTRACT:
An apparatus applicable to a sheet article processing system for temporarily accumulating sheet articles which come in arbitrarily one by one or in a bunch and sending them out one by one at predetermined intervals. The apparatus includes a drive mechanism capable of starting and stopping the movement of a suction belt instantaneously, a sensor responsive to the leading edge of a sheet article which has been nipped by a downstream transport path, and a sensor responsive to the presence/absence of an interval between successive sheet articles which occurs between the downstream transport path and a reverse belt. Other sensors are provided for determining an interval between successive articles. A pick-up roller pair is driven at a controllable speed in matching relation to the interval between successive articles determined.
