Abstract
Abstract Apparatus for copying documents and/or books. A book-like housing is pivotally mounted in overlying relationship to a copying machine. The top wall of the housing is pivotally mounted also to obtain free acess to the platen and has a diaphragm assembly mounted therein for restraining books placed in the housing against the platen of the copying machine. A document transport co-extensive with the platen is pivotally mounted on the housing for movement from a first position wherein the document transport feeds documents into overlying relationship with said platen to a second position away from said platen where books may be positioned in overlying relationship thereto.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
136 words
Apparatus for copying documents and books comprising: a frame; a platen positioned on said frame; contiguous walls defining a hollow box-like housing mounted on said frame in overlying relationship to said platen; a one of said walls forming a top cover for said housing and being pivotally mounted to said housing to obtain free access to said platen; document transport means pivotally mounted within said housing for movement between a first position in which it is coextensive with and overlies said platen for feeding documents into overlying relationship with said platen and a second position in which said transport means is pivoted away from said platen and outside said housing with said housing top cover being closed over said platen such that a book may be placed on said platen and held by said top cover.
Claim 2
Dependent Claim
136 words
Apparatus for copying documents and books comprising: a frame; a platen positioned on said frame; contiguous walls defining a hollow box-like housing mounted on said frame in overlying relationship to said platen; a one of said walls forming a top cover for said housing and being pivotally mounted to said housing to obtain free access to said platen; document transport means pivotally mounted within said housing for movement between a first position in which it is coextensive with and overlies said platen for feeding documents into overlying relationship with said platen and a second position in which said transport means is pivoted away from said platen and outside said housing with said housing top cover being closed over said platen such that a book may be placed on said platen and held by said top cover.
Claim 3
Dependent Claim
28 words
Apparatus according to claim 1 wherein said box-like housing is pivotally mounted on said frame for movement toward and away from said platen for positioning oversize sheets thereon.
Claim 4
Dependent Claim
151 words
Apparatus for copying documents and books comprising: a frame; a platen positioned on said frame; contiguous walls defining a hollow box-like housing mounted on said frame in overlying relationship to said platen; a one of said walls forming a top cover for said housing and being pivotally mounted to said housiNg to obtain free access to said platen; document transport means co-extensive with said platen and pivotally mounted on said housing for movement from a first position wherein said document transport means feeds documents into overlying relationship with said platen to a second position away from said platen where books may be positioned in overlying relationship thereto; wherein said top wall of said housing is formed with an opening and a diaphragm means is secured to said top wall member and arranged co-extensive therewith whereby pressure exerted on said diaphragm means may be imparted to a book overlying said platen area.
Claim 5
Dependent Claim
151 words
Apparatus for copying documents and books comprising: a frame; a platen positioned on said frame; contiguous walls defining a hollow box-like housing mounted on said frame in overlying relationship to said platen; a one of said walls forming a top cover for said housing and being pivotally mounted to said housiNg to obtain free access to said platen; document transport means co-extensive with said platen and pivotally mounted on said housing for movement from a first position wherein said document transport means feeds documents into overlying relationship with said platen to a second position away from said platen where books may be positioned in overlying relationship thereto; wherein said top wall of said housing is formed with an opening and a diaphragm means is secured to said top wall member and arranged co-extensive therewith whereby pressure exerted on said diaphragm means may be imparted to a book overlying said platen area.
