Abstract

The illustration depicts a sheet set separator which may be incorporated in a document sheet handling apparatus for use in an electrostatic reproduction machine or copier. The set separator is a low cost, highly reliable device for identifying end-of-set or tray empty conditions for a bottom document sheet feeder.

ROTATING CAM SET SEPARATOR (Cont'd)

The illustration depicts a sheet set separator which may be incorporated in a document sheet handling apparatus for use in an electrostatic reproduction machine or copier. The set separator is a low cost, highly reliable device for identifying end-of-set or tray empty conditions for a bottom document sheet feeder.

The set separator includes a solenoid 1 which, when energized, rotates a cam 2 about a point 3 having a multi-facet scanning surface as illustrated in Figure 2. A set separator finger 4 having a cam following elbow section 5 and mounted on a flexible coupler 6 serves to separate the last sheet of a set of document sheets from the first sheet of the set during recirculation of the document sheets in the sheet handling apparatus. The coupler normally slightly biases the elbow 5 downwardly and toward the outside flange of the cam 2 as viewed in Figure 2.

In operation, assuming a set of document sheets have been placed in the document tray of the document handling apparatus and the finger 4 is resting upon the topmost sheet of the set, generally the last sheet, as the sheets in the set are fed from the stack to be copied and returned to the stack above the finger 2, the elbow 5 slides down the inclined curved cam surface 2a under the bias of the coupler 6. The finger 2 is carried along during this motion of the elbow. When the last sheet is fed from the stack,...
