Abstract

Abstract In a document handler for a copier or scanner imaging station in which a separate document input loading tray and a document restacking output tray are provided, but with both trays being superposed over the imaging station and one another for compactness; the document input tray is only partially underlying the output tray, has a substantially fully supportive surface, and is adapted to fully support document feeding into an input end of the document handler; and the document restacking output tray (except for an initial portion at its opposite end entrance area) consists of only a thin, rear edge only, shelf, overlying not more than a minor rear portion of the input tray in at least that portion of the input tray adjacent the input end of the document handler into which documents are to be fed, so as to provide open document loading access. The width of the document restacking output tray rapidly arcuately transitions by narrowing to this thin rear edge shelf portion as it extends away from the output end of the document handler. This tray may be a semi-transparent plastic plate, and the initial portion may have an uphill slope.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 288 words
In a document handler for a copier or scanner imaging station having a document loading input tray and a separate document restacking output tray, with both said document loading input tray and said document restacking output tray being positioned to be vertically superposed over said imaging station for overall compactness of said document handler; and wherein documents are fed from said document loading input tray into an input end of said document handler and wherein documents are fed from an opposite, output, end of said document handler into said restacking output tray; the improvement wherein: said document loading input tray comprises a substantially planar and fully supportive tray surface for fully supporting documents feeding into said input end of said document handler, said document restacking output tray is spaced above said document input tray and is adapted to receive thereon but only partially support documents for restacking thereon which are ejected from said opposite, output, end of said document handler, said document restacking output tray being adapted to support only a minor portion of said restacking documents therein, said document restacking output tray primarily comprising only a thin, rear edge, shelf portion overlying only a minor rear portion of said document loading input tray, said document restacking output tray having only a minor initial portion adjacent only said output end of said document handler having a front to rear width substantially overlying said document input tray, and said width of said document restacking output tray rapidly narrows to said thin, rear edge shelf portion as said document restacking output tray extends away from said output end of said document handler, so as to provide unobstructed document loading access to a major area of said document loading input tray.
Claim 2
Dependent Claim 288 words
In a document handler for a copier or scanner imaging station having a document loading input tray and a separate document restacking output tray, with both said document loading input tray and said document restacking output tray being positioned to be vertically superposed over said imaging station for overall compactness of said document handler; and wherein documents are fed from said document loading input tray into an input end of said document handler and wherein documents are fed from an opposite, output, end of said document handler into said restacking output tray; the improvement wherein: said document loading input tray comprises a substantially planar and fully supportive tray surface for fully supporting documents feeding into said input end of said document handler, said document restacking output tray is spaced above said document input tray and is adapted to receive thereon but only partially support documents for restacking thereon which are ejected from said opposite, output, end of said document handler, said document restacking output tray being adapted to support only a minor portion of said restacking documents therein, said document restacking output tray primarily comprising only a thin, rear edge, shelf portion overlying only a minor rear portion of said document loading input tray, said document restacking output tray having only a minor initial portion adjacent only said output end of said document handler having a front to rear width substantially overlying said document input tray, and said width of said document restacking output tray rapidly narrows to said thin, rear edge shelf portion as said document restacking output tray extends away from said output end of said document handler, so as to provide unobstructed document loading access to a major area of said document loading input tray.
Claim 3
Dependent Claim 18 words
The document handler of claim 1, wherein said document restacking output tray is a thin, semi-transparent plastic plate.
Claim 4
Dependent Claim 23 words
The document handler of claim 1, wherein at least said minor initial portion of said document restacking output tray has an uphill slope.
