Abstract: A shaker conveyor assembly including a housing, a drive system supported by the housing and at least one transport tray supported by the housing and operatively connected to the drive system. The drive system includes an electric motor that produces a rotary output. A cam assembly is operatively connected in driven relationship to the rotary output of the electric motor so as to rotate therewith. A cam follower assembly is operatively connected to the transport tray and is responsive to the rotation of the cam assembly to produce repeated, reciprocating, linear motion and to transmit this motion to the transport tray so as to convey items therealong.

Abstract: A shaker conveyor assembly for moving objects includes a conveying element adapted for movement in first and second directions in repeated rectilinear fashion so as to convey items placed on the conveying element in one of the directions. The assembly includes an electric drive assembly having an output, a control assembly, and at least one sensor adapted to sense movement of the output. The control assembly provides a first level of electrical power to the electric drive assembly during a first portion of reciprocal movement and a second level of power to the electric drive assembly during a second portion of reciprocal movement. In addition, the control assembly provides selective control over the duration of the first and second portions of the reciprocal movement thereby controlling the speed of each of the directions of reciprocal movement of the conveying element.

Abstract: A copy machine (10) of the type for producing enlargements or reductions of an original material includes mirrors (14) for reflecting an image of the original material to a lens (16) and from the lens (16) to an image fixing system (18), and a lens (16) for enlarging or reducing the image reflected thereto by the mirrors (14). The lens (16) is fixed relative to the machine (10). The image fixing system (18) fixes the reflected image on a substrate. The mirrors (38,40,44,46) are moveable for enlarging or reducing the image reflected to and from the lens (16). The machine (10) includes a control system (20) for controlling the movement of the mirrors (38,40,44,46) and simultaneously reducing or enlarging and focusing the image reflected to the image fixing system (18).
