Abstract
Abstract An improved electrostatic copying machine in which documents to be reproduced are transported along alternate paths to exit at the front or the rear of the machine and in which copies produced are transported along alternate paths to exit at the front or rear of the machine. One of the copy paths intersects with the document path. An electrical control enables different combinations of the document and copy paths to be effected at the option of a machine operator while preventing a combination with the path of intersection between document and copy.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
86 words
An improved electrostatic copying machine for handling documents to be reproduced and copies produced along alternate transport paths comprising: means for transporting documents along first or second paths, means for transporting copies along third or fourth paths wherein a one of said copy paths intersects with a one of said document paths, and control means for selectively transporting the documents and copies along a desired predetermined path at the option of a machine operator while preventing a combination which would result in the aforementioned intersecting paths.
Claim 2
Dependent Claim
86 words
An improved electrostatic copying machine for handling documents to be reproduced and copies produced along alternate transport paths comprising: means for transporting documents along first or second paths, means for transporting copies along third or fourth paths wherein a one of said copy paths intersects with a one of said document paths, and control means for selectively transporting the documents and copies along a desired predetermined path at the option of a machine operator while preventing a combination which would result in the aforementioned intersecting paths.
Claim 3
Dependent Claim
16 words
The machine of claim 1 wherein one of the document paths is a substantially plane path.
Claim 4
Dependent Claim
70 words
The machine of claim 1 wherein one of said document paths and one of said copy paths are such as to deliver the document and copy respectively to the front of the machine, and the other document path and the other copy path are such as to deliver document and copy respectively to the rear of the machine, the rear document path and the front copy path intersecting one another.
Claim 5
Dependent Claim
83 words
The machine of claim 3 wherein said control means for transporting the document and copy to follow the selected paths comprises a document exit selection switch and a copy exit selection switch, the document exit switch actuating a document direction selecting device, and the copy exit selection switch actuating a copy direction selecting device, the copy exit selection switch being operable to direct the copy to the front onlY if the document exit selection switch has been operated to select the front exit.
Claim 6
Dependent Claim
27 words
The machine of claim 4 wherein the document direction selecting device is a solenoid operated baffle and the copy direction selecting device is a solenoid operated baffle.
