Abstract
Abstract A machine for automatically producing images from photoelectrophoretic suspensions using a cylindrical transparent conductive electrode which is inked and contacted by an imaging electrode in the presence of an electric field and electromagnetic radiation in image configuration. The cylinder electrode is cleaned and an image transferred from its surface to a transfer material. The electromagnetic radiation is imaged at the intersection of the transparent cylindrical electrode and the imaging electrode. The projection passes from the end of the transparent cylindrical electrode to an internal mirror for reflection to the intersection.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
29 words
The apparatus of claim 1 including suspension application means to apply photoelectrophoretic suspension to one of said members along the path of movement thereof prior to the interfacing therebetween.
Claim 2
Dependent Claim
34 words
The apparatus of claim 1 wherein said transparent member has operatively associated therewith cleaning means located in the path of rotation of the transparent member and removably positionable to contact the outer surface thereof.
Claim 3
Dependent Claim
37 words
The apparatus of claim 3 including image transfer means capable of removing suspension from the transparent member and removably positionable to interface with the transparent member along the path of travel thereof downstream from said electrode member.
Claim 4
Dependent Claim
33 words
The apparatus of claim 4 further including feed means for presenting a support material between said transparent member and said image transfer means such that the image is transferred to the support material.
Claim 5
Dependent Claim
23 words
The apparatus of claim 5 wherein said support material includes a web wherein said web is cut after transfer of the image thereto.
Claim 6
Dependent Claim
13 words
The apparatus of claim 3 wherein said suspension application means includes an extruder.
Claim 7
Dependent Claim
22 words
The apparatus of claim 7 further including a smoothing means upstream from the extruder along the path of movement of the member.
Claim 8
Dependent Claim
20 words
The apparatus of claim 3 including means to remove said suspension application means from the member with which it interacts.
Claim 9
Dependent Claim
37 words
The apparatus of claim 1 wherein said optical system includes a lens means having an object plane and an image plane and wherein said transparent member outer surface passes through the image plane at the image zone.
Claim 10
Dependent Claim
20 words
The apparatus of clAim 1 including electrode member cleaning means positioned in the path of travel of said electrode member.
Claim 11
Dependent Claim
18 words
The apparatus of claim 1 including means for applying electrical charge to the surface of said electrode member.
Claim 12
Dependent Claim
13 words
The apparatus of claim 1 wherein said electrode member comprises an endless belt.
Claim 13
Dependent Claim
28 words
The apparatus of claim 1 including means to spray fluids on the surface of the electrode member upstream from the interface of said member with said transparent member.
Claim 14
Dependent Claim
40 words
The apparatus of claim 1 wherein said optical projection system includes a movable object and image plane for presenting a flowing image of the object at the image plane moving at the same rate as said transparent member surface thereat.
