Abstract

The present invention proposes a double sided, half rate and full rate drive system for a xerographic scanner. A single cable replaces the normal complex multiple cable system through the implementation of multiple pulleys. As illustrated in the Figure, there is shown shaft L representing a half rate carriage and shaft M or M representing a full rate carriage. The drive system utilizes a single cable 20 attached at ends A and J. Cable 20 is wrapped around various other pulleys including B, C, D, E, F, G, H, and I to provide stationary cable sections comprising A-B, B-G,

DOUBLE SIDED HRPR DRIVES SYSTEM WITH SINGLE CABLE(Cont'd)

The present invention proposes a double sided, half rate and full rate drive system for a xerographic scanner. A single cable replaces the normal complex multiple cable system through the implementation of multiple pulleys. As illustrated in the Figure, there is shown shaft L representing a half rate carriage and shaft M or M representing a full rate carriage. The drive system utilizes a single cable 20 attached at ends A and J. Cable 20 is wrapped around various other pulleys including B, C, D, E, F, G, H, and I to provide stationary cable sections comprising A-B, B-G, G-H, H-I, and I-J. In operation, these portions of the cable remain fixed while all other portions of the cable travel at the same speed as the full-rate load bearing body. This results in the desired half-rate and full-rate carriage motions.

Clamp K normally locks the two portions of the cable 20 between pulleys D and E to prevent rotational motions of the carriages L, M, or M about the 2 axis.
