Abstract
A paper sheet manipulator has a main manipulation member, an auxiliary manipulation member and devices for moving the main and auxiliary manipulation members. The main manipulation member is adapted to temporarily receive the front edges of paper sheets being fed for the purpose of accumulating the paper sheets into a sheet unit composed of a prescribed number of accumulated paper sheets, whereas the auxiliary manipulation member is adapted to press down the sheet unit to form a sufficient gripper insertion space between the sheet unit and the temporarily received paper sheets and suppress swelling and play of the upper layer of the sheet unit, thereby eliminating the drawbacks suffered by the conventional paper takeout and supply apparatus in operating a gripper of the apparatus for taking out and supplying to the subsequent step the sheet unit.
