Abstract: PURPOSE: To provide a paper feeder of a paper sheet processing machine which has a retaining device for a quick-responsive lifting sucker simple and unlockable quickly by providing a pneumatic device controlled for moving the retaining device following movement of the lifting sucker to lift sheets. CONSTITUTION: Paper sheets are sucked by a nozzle 6 and then a lifting sucker 5 is lifted against the action of a spring 16. When the lifting sucker is raised to an upper position, suction air immediately acts on a pneumatic cylinder 8, in which case a guide pin 10 stops when abutting against the stopper surface 13 of the lifting sucker 5 at the upper position. When the paper sheets floated are completely separated from the range of lifting motion of the lifting sucker 5, an air cycle for the pneumatic cylinder 8 is vented and the retaining force of the pin 10 is canceled immediately at the same time. The lifting sucker 5 falls downward to suck the next paper sheet by means of the resilient force of the spring 16 and the weight of the sucker 5 itself.
