Scanning Illumination Drive

Proper synchronism between an illumination source and a moving photo receptive surface is maintained with a relatively low-inertia drive system.

Lamp 11 is driven in the direction of arrow 13 in synchronism with a moving photoreceptive surface, the photoreceptive surface controlling the reciprocal motion of arm 15. Arm 15 drives timing belt assembly 17 through bracket 19 secured to belt 17. Belt 17 drives shaft 21 which in turn drives two timing belts 23 and 24 through pulleys 25 and 26. Motion of belts 23 and 24 effects reciprocal motion of carriage 27 along guides 29, thereby effecting reciprocal drive of lamp 11. Pulleys 25 and 31 and arm 15 can be proportioned to provide a velocity ratio between lamp 11 and the photoreceptive surface. Timing belts 17, 23, and 24 provide a high stiffness to weight ratio in the drive.
