Apparatus for transporting a sheet comprising, a frame including an elongate generally rectangularly-shaped upper wall having opposite ends, at least one endless belt looped about the upper wall, the at least one belt including a belt run overlaying the upper wall and extending longitudinally of the length thereof between the opposite upper wall ends, a d.c. motor supported by the frame and connected for driving the at least one belt in opposite directions, structure for connecting the apparatus to a source of supply of a.c. power, the connecting structure including a power switch operable for energizing the apparatus, structure for controlling energization of the motor, the controlling structure including a two position switch supported by the frame, the switch selectively actuatable for energizing the motor to drive the at least one belt in either of the opposite directions for moving the belt run(s) thereof in either direction between the opposite upper wall ends, the controlling structure including structure for sensing a sheet fed to the upper wall and thus to the belt run(s), the sensing structure including a sensor removably connectable to different positions on the apparatus for sensing sheets fed from different directions toward the belt run(s), and the controlling structure including structure responsive to the sensing structure sensing a sheet for energizing the motor.
