ABSTRACT:
An automatic paper ejecting and stacking machine for use with vertically-loaded desktop hole-punching equipment is disclosed. The ejector and stacker work together to remove vertically-fed paper stacks from a hole punch and align said stacks in a horizontal stacking bin adjacent the punch machine and preferably facing the operator. After the sheets are punched, a sheet transfer mechanism moves the vertically-oriented media stack in a horizontal direction from the punch machine/ejection assembly to the reception assembly. The sheet transfer mechanism may comprise a plurality of transfer paddles arranged on an drive belt wherein a motor rotates the belt to draw a paddle through the paper-receiving channel of the ejection assembly to push the media stack out of the channel. In one version, the media stack is flipped forward to rest in a forward-facing tray, while in another embodiment, the media stack is pushed rearward to rest in a rear-facing tray.
