Collating system for slide reproduction

Claim 2

An electrostatographic printing machine for reproducing a plurality of transparencies, including: means for storing the transparencies in an operator selectable ordered sequence; means for reproducing each one of the transparencies to form at least one set of copies thereof; means, operatively associated with said storing means, for indexing automatically said storing means to advance successive transparencies into cummunication with said reproducing means to form copies thereof; and programming means, coupling said reproducing means with said storing means, for actuating said storing means in response to said reproducing means completing the copying of one of the transparencies to advance the next successive transparency into communication with said reproducing means to form a copy thereof.

Claim 3

A printing machine as recited in claim 1, wherein said storing means includes a cylindrical member having a plurality of radially extending compartments, each compartment being arranged to have a transparency disposed therein.

Claim 4

A printing machine as recited in claim 2, wherein said indexing means includes an indexing motor having said cylindrical member mounted rotatably thereon.

Claim 5

A printing machine as recited in claim 3, wherein said reproducing means includes: a photoconductive member; means for charging at least a portion of said photoconductive member to a substantially uniform level; and means, coupled to said cylindrical member, for projecting a light image of one of the transparencies onto the charged portion of said photoconductive member selectively dissipating the charge thereon to record an electrostatic latent image thereof.

Claim 6

A printing machine as recited in claim 4, wherein said reproducing means includes: a receiving member; a composition frame disposed on said receiving member; and means for exposing the charged portion of said photoconductive member to a light image of said composition frame recording thereon a combined electrostatic latent image comprising the electrostatic latent image of the transparency and the electrostatic latent image of said composition frame.

Claim 7

A printing machine as recited in claim 5, wherein said reproducing means includes means for filtering the light image of the transparency to form a single color light image thereof which irradiates the charged portion of said photoconductive member to record thereon a single color electrostatic latent image.

Claim 8

A printing machine as recited in claim 6, wherein said reproducing means includes means for modulating the light image of the transparency.

Claim 9

A printing machine as recited in claim 7, wherein said receiving member includes: a transparent platen member having said composition frame disposed thereon; and a field lens mounted on said composition frame.

Claim 10

A printing machine as recited in claim 8, wherein said modulating means includes a screen interposed between said field lens and said composition frame.

Claim 11

A printing machine as recited in claim 9, wherein said projecting means includes a slide projector arranged to project a light image of successive transparencies.

Claim 12

A printing machine as recited in claim 10, wherein said exposing means includes: a light source arranged to illuminate said composition frame disposed on said receiving member; and lens means for receiving the light rays from the combined image of the transparency and said composition frame.

Claim 13

A printing machine as recited in claim 11, further including means, movable from a first position remote from the path of the light image to reproduce an opaque original document to a second position in the path of the light image to reproduce the transparency, for directing the light image of the transparency onto the charged portion of said photoconductive member.

Claim 14

An electrophotographic printing machine for reproducing a plurality of transparencies, including: a cylindrical member having a plurality of radially extending compartments for holding a transparency therein; a photoconductive member; means for charging at least a portion of said photoconductive member to a substantially uniform level; a slide projector arranged to project a light image of successive transparencies; a transparent platen member; a composition frame disposed on said transparent platen member; a field lens mounted on said composition frame; a screen interposed between said field lens and said composition frame; an indexing motor having said cylindrical member mounted rotatably thereon; programming means for actuating said indexing motor in response to completing the copy of one of the transparencies to advance the next successive transparency into communication with said slide projector; a frame supporting said slide projector; an arm having one end portion thereof mounted pivotably on said frame; a mirror mounted movably on the other end portion of said arm to direct the light image of the transparency through said transparent platen, said composition frame, said screen and said field lens; a light source arranged to illuminate said composition frame disposed on said transparent platen member; lens means for receiving the light rays from the combined image of the transparency and said composition frame; and means for filtering the combined light image of the composition frame and transparency to form a single color light image thereof which irradiates the charged portion of said photoconductive member to record thereon a single color electrostatic latent image.

Claim 15

An electrophotographic printing machine for reproducing a plurality of transparencies, including: a cylindrical member having a plurality of radially extending compartments for holding a transparency therein; a photoconductive member; means for charging at least a portion of said photoconductive member to a substantially uniform level; a slide projector arranged to project a light image of successive transparencies; a transparent platen member; a composition frame disposed on said transparent platen member; a field lens mounted on said composition frame; a screen interposed between said field lens and said composition frame; an indexing motor having said cylindrical member mounted rotatably thereon; programming means for actuating said indexing motor in response to completing the copy of one of the transparencies to advance the next successive transparency into communication with said slide projector; a frame supporting said slide projector; an arm having one end portion thereof mounted pivotably on said frame; a mirror mounted movably on the other end portion of said arm to direct the light image of the transparency through said transparent platen, said composition frame, said screen and said field lens; a light source arranged to illuminate said composition frame disposed on said transparent platen member; lens means for receiving the light rays from the combined image of the transparency and said composition frame; and means for filtering the combined light image of the composition frame and transparency to form a single color light image thereof which irradiates the charged portion of said photoconductive member to record thereon a single color electrostatic latent image.

Claim 16

A printing machine as recited in claim 13, wherein said filtering means includes: a red filter arranged to be interposed into the light image path to transmit a red light image therethrough; a blue filter arranged to be interposed into the light image path to transmit a blue light image therethrough; and a green filter arranged to be interposed into the light image path to transmit a green light image therethrough.

Claim 17

A printing machine as recited in claim 14, wherein said screen includes a plurality of spaced, soft gray square dots.

Claim 18

A printing machine as recited in claim 15, wherein said screen includes preferably about 85 dots per inch.

Claim 19

A printing machine as recited in claim 16, wherein said field lens includes a Fresnel lens having preferably about 200 gratings per inch.
