Abstract: The bank notes in a bank note container are delivered one at a time by means of feed rollers and a delivery roller. The delivered bank notes are detected by sensor means. A signal from the sensor means is transferred to a control mechanism which drives or stops the delivery roller. The delivery roller is stopped and is driven again in response to a signal from an encoder carried by a supporting shaft of pull rollers. Therefore the bank notes are delivered from the bank note delivery container to the outside thereof in a predeterminedly spaced apart relationship.

Abstract: In a stacker drum of a sheet accumulating device for stacking paper money and the like, which stacker drum has around its cylindrical surface several blades secured at their inner root parts to the drum and extending tangentially in the direction opposite to the drum rotational direction to their outer ends, a curved leaf spring is secured to each blade in a manner to narrow the space between each pair of adjacent blades thereby to prevent disturbance of the steady flow of sheets such as paper money fed to and entering respective spaces between the blades to be accumulated into a neat stack.
