Paper Moving Stylus

A device used in a paper accumulator tray to position single sheets of paper with respect to the tray's reference edges.

The device consists of an aligning blade 10 connected to a hinge/spring element 11, which in turn is connected through a hinged actuating frame 12 to body 13 of the tray. Two coils 14 and 15 provide the energy for activating the device.

A return spring 16 removes the blade from the path of the paper in the deactivated mode. On activation of coil 14, blade 10 is drawn down into the path of the paper, causing the blade to act as a damper or deaccelerator on the incoming paper sheet. The blade is now in contact with the paper, and is vibrated with a pulsed energization signal through coil 15, causing the paper to move to the alignment edge (not shown). The spring blade has low column strength and deflects when the paper has registered against the reference edge. The amplitude of the vibration of the blade is controlled by up-stop 17 on frame 12.

Two of these devices can provide x and y positioning to corner sheets in a tray.
