further actuates gripper 14. Winding mechanism 19 includes ratchets 20, pawl 22, and a large pulley 24. The manual loader and unloader 10 can be clamped to the front of an RDH by way of a mounting bracket 18. Mounting bracket 18 positions loader and unloader 10 upside down on the RDH so that crank handle 16 is at RDH leveL Manual loader and unloader 10 accepts original documents at the vertical elevation of the user and transports the documents upwards to the RDH. Once the original documents are cycled through the RDH (for copying), the user activates the manual loader and unloader 10 to retrieve the documents.

This is accomplished by transferring the users motion through pulleys 28 and 30, and a timing belt 32. Similarly, a user having diminished or no finger dexterity can operate manual loader and unloader 10 by actuating a crank handle 16 and a release button (not shown). These controls are accessible to the user and need only be pushed a short distance to operate the winding mechanism 19.
