Abstract: The present invention is a system that enables a plurality of external peripheral devices to be easily connected to a conventional personal computer, or other computing device. The system can include the computer, or can alternatively be configured as a hub. In either configuration, the system includes an arcuate-shaped interface surface, on a base. One end of the interface surface includes an upright chassis, which includes a plurality of bays. Rails extend longitudinally along the interface surface, toward each bay. An external peripheral device is slid over a rail, which provides attachment and stability to the device and aligns it with the bay. Each bay includes an alignment pin, a power connection, and a data connection. Adjacent to each rail is a latch for securing an external peripheral device in a bay. The top of the chassis includes a marking to provide a visual reference that aids in attaching an external peripheral device to a bay.

Abstract: An apparatus (10) for spiral binding a stack of papers (24) together as a unit. The apparatus includes a punch (12) for punching a plurality of holes (23) along one edge of the stack of papers and a spiral binding unit (14) for feeding a spiral coil (36) into the holes. The spiral binding unit (14) includes an aperture (44) through which a coil is inserted between a shoe (74) and a rotatably mounted roller (72). As the coil (36) is inserted, the shoe (74) pushes the coil into contact with the roller (72). As the roller (72) rotates, the coil (36) is guided through a series of slots (86) which cause the coil to spiral into the holes in the stack of paper. The punch (12) includes a ramp (186) that presses a series of punch pins (188) through the stack of papers. The ramp (186) includes a plurality of steps (222) that incline upwardly on either side of a center step (224). The punch first punches holes in the center of the stack of papers and then punches holes outward from either side of the center.
