Abstract
Abstract Disclosed is an electrophotographic copying machine which is provided with an original-setting table and copying-paper delivery devices featuring provision of a original-setting plate that allows a plurality of originals to be mounted on the original-setting table, circuits for generating timing signals matching the positions of a plurality of originals mounted together with the original-setting plate on the original-setting table, and a copying-paper feeding device for delivering copying papers in response to the timing signals thus generated.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
166 words
An electrophotographic copying machine provided with an original-setting table and copy-paper feeding means comprising: an original-setting plate having a plurality of openings formed therein and overlaying said original setting table for allowing a plurality of originals to be mounted on said original-setting table according to said plurality of window openings; a plurality of timing detection marks provided on said said original setting plate at predetermined positions between each said plurality of window openings for automatically defining a number of said plurality of originals to be copied; means for generating a plurality of timing signals matching the predetermined positions of each said plurality of timing detection marks defining said plurality of originals mounted together with said original-setting plate on said original-setting table; and means for sequentially feeding a plurality of said copy papers in response to each of said plurality of timing signals, whereby each of said plurality of originals is copied onto a corresponding one of said plurality of copy papers in a single copying operation.
Claim 2
Dependent Claim
166 words
An electrophotographic copying machine provided with an original-setting table and copy-paper feeding means comprising: an original-setting plate having a plurality of openings formed therein and overlaying said original setting table for allowing a plurality of originals to be mounted on said original-setting table according to said plurality of window openings; a plurality of timing detection marks provided on said said original setting plate at predetermined positions between each said plurality of window openings for automatically defining a number of said plurality of originals to be copied; means for generating a plurality of timing signals matching the predetermined positions of each said plurality of timing detection marks defining said plurality of originals mounted together with said original-setting plate on said original-setting table; and means for sequentially feeding a plurality of said copy papers in response to each of said plurality of timing signals, whereby each of said plurality of originals is copied onto a corresponding one of said plurality of copy papers in a single copying operation.
Claim 3
Dependent Claim
15 words
The copying machine according to claim 1, wherein said plurality of originals are very small.
Claim 4
Dependent Claim
78 words
The copying machine according to claim 1, wherein said means for generating a plurality of timing signals is a sensor positioned in a fixed location beneath said original-setting table for photoelectrically detecting each said plurality of timing detection marks, whereby said sensor detects the position of each said plurality of originals in response to the presence and absence of light reflection, and wherein one of said plurality of copy papers is delivered for each said timing signal generated.
