A drive mechanism is provided for interconnection between a motor having a substantially constant rotational output and a linear motion conveyor. The linear motion conveyor includes a tray which may be movable in a first reciprocating direction at a slow speed, then in a backward reciprocating direction at a second speed to move goods along the tray. The drive mechanism includes universal joint for interconnection between the output shaft of the motor and a second shaft, such that the rotational speed of the second shaft varies as a function of the angle between the motor output and the second shaft output. A speed reducer is provided between the second shaft and a third shaft, and a crank interconnects the third shaft with the tray to move goods along the tray. This drive mechanism may also be used to drive a tray configured in spiral and thereby convey product vertically.
