Abstract

A scan drive mechanism with a sled and a flexible shade to replace a conventional optics carriage structure. As shown in the figure, scan drive 10 incorporates a shade or partial belt section 22, attached to the lead edge of an optics support or a sled 20. The shade 22 is wrapped over an idler tube 24, which is supported by a single self-aligning bearing (not shown) located at the center of the tube. A cable 12 is attached to the shade 22 and continues on to a capstan 18. From the capstan 18, the cable 12 continues over an idler pulley 16, wherein the cable 12 is attached to the trail edge of the sled 20. The sled 20 rides on runners 24, which are incorporated into the frame (not shown) of the scan drive mechanism.

SHADEKABLE SCAN DRIVE (Cont'd)

A scan drive mechanism with a sled and a flexible shade to replace a conventional optics carriage structure. As shown in the figure, scan drive 10 incorporates a shade or partial belt section 22, attached to the lead edge of an optics support or a sled 20. The shade 22 is wrapped over an idler tube 24, which is supported by a single self-aligning bearing (not shown) located at the center of the tube. A cable 12 is attached to the shade 22 and continues on to a capstan 18. From the capstan 18, the cable 12 continues over an idler pulley 16, wherein the cable 12 is attached to the trail edge of the sled 20. The sled 20 rides on runners 24, which are incorporated into the frame (not shown) of the scan drive mechanism.

The distance between the end of the shade 22 and the capstan 18 is equal to the required scan length.

The disclosed scan drive mechanism improves the dynamic stiffness of an
optics carriage structure to provide greater stability and better motion quality.
