Self Guided Paper Transport

The device shown schematically is a paper transport wherein a coil bobbin assembly is self-guided.

Fig. 1 shows a.side view of the device. The device is comprised of magnetic structure support 10 and coil bobbin assembly 12. The coil bobbin assembly is positioned within the air gap of magnetic structure support 10. A U-shaped spring member 14 is attach to coil bobbin assembly 12 and magnetic structure support 10. A rubber pad 16 is operably attached to the lower side of spring 14. The device is positioned to form a 15 degrees angle with a substantially flat table support 18.

In operation, a stack of paper is placed on table support 18. The table is adjusted so that the topmost sheet is in contact with rubber pad 16. By passing current with appropriate polarity through the actuator coil, bobbin assembly 12 will move in the direction shown by arrow 20. Simultaneously, rubber pad 16 will transport paper in the direction shown by arrow 22. At the end of the stroke, spring 14 will return coil bobbin assembly 12 to its original position; i.e., to the beginning of its stroke. The action will repeat as many times as is required.

Fig. 2 shows the bottom view of the device. The device is comprised of magnetic return shell support 26. Magnetic return path 28 is operably connected to shell support 26, while air gap positioning plate 30 is also attached to shell support 26. Shock pads 32, 34, 36 and 42 are, respectively, attached to each corner of...
