First Claim:
Show all claims		 We claim:
1. A belt tensioning mechanism for tensioning a belt that transmits torque from a motor to a rotary member having an axis of rotation, the belt tensioning mechanism comprising: a. a motor having a roller for engaging the belt; b. a cam plate having a slot ridge for receiving the motor, a rotation ridge disposed eccentrically with respect to the slot ridge, and a plurality of circumferential sprocket teeth; and c. a transmission plate fixed with respect to the axis of rotation of the rotary member, the motor having a rotational orientation defined with respect to the transmission plate, the transmission plate having a substantially elliptical cam plate rotation shelf for receiving the cam plate rotation ridge such that a lateral position of the motor with respect to the transmission plate may be changed by rotation of the cam plate while the rotational orientation of the motor remains substantially constant.
