Abstract: A chair for providing support and corrective forces to a patient having scoliotic, lordotic or kyphotic conditions includes parallel side panels with parallel vertical slots on the inner faces and slats extending between the panels. The slats have end fittings which are selectably insertable in the slots with the bottom of each slat resting on the one below so that the slats define a generally curvilinear surface having predetermined curvatures. Devices for holding straps and pads to apply lateral forces in a predetermined manner are also provided. Specific slat structure and full adjustability is provided.

Abstract: A conveyor belt (14) conveys a document (19), (32) over a transparent glass platen (10) to a scanning position. An automatic document feed unit (22), (26) feeds documents (19) from a stack one by one between the lower run of the belt (14) and the platen (10) for conveyance over the platen (10). A manual feed unit (34) feeds documents (32) manually inserted thereinto one by one onto the upper run of the belt (14) from which the documents (32) are guided downwardly over an end of the belt (14) between the lower run of the belt (14) and the platen (10) for conveyance over the platen (10). The relative positions of the automatic and manual feed units (22), (26); (34) may be reversed. The documents (19), (32) are discharged by the belt (14) onto a tray (54) after scanning.
