Abstract
Abstract An electrophotographic copying machine having an editorial function includes a switch for setting "moving" mode. On the other hand, position whereto an original image should be moved and reproduced is designated by a mouse. The position is set and the switch is operated, then a microcomputer makes a movable light source or an original table to move in accordance with an inputted positional data prior to an acutal copying operation. During this moving of the movable light source, the microcomputer preliminarily measures a resist clutch ON timing when a toner image will be just transferred on the designated position. In actual copying operation, the resist clutch ON timing is controlled based on a time data measured by the microcomputer in the preliminary moving of the light source.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
195 words
An electrophotographic copying machine having an editorial function, comprising position designating means for designating a position or positions whereto an image is to be moved; an original table for placing an original; an optical system for optically scanning the original placed on said original table; moving means for relatively moving said original table and said optical system in accordance with the position or positions designated by said position designating means; actually measuring means for actually measuring time necessary for forming a moved image copy during relative movement of said original table and said optical system, said actually measuring means including means for measuring said time while said original table and said optical system are relatively and preliminarily moved by said moving means when only one moved image copy is to be formed, and means for measuring said time necessary for forming a succeeding moved image copy while a preceding moved image copy is formed when a plurality of moved image copies are to be formed in accordance with the same designated position or positions; and image forming means for forming a moved image copy based on the time actually measured by said actually measuring means.
Claim 2
Dependent Claim
195 words
An electrophotographic copying machine having an editorial function, comprising position designating means for designating a position or positions whereto an image is to be moved; an original table for placing an original; an optical system for optically scanning the original placed on said original table; moving means for relatively moving said original table and said optical system in accordance with the position or positions designated by said position designating means; actually measuring means for actually measuring time necessary for forming a moved image copy during relative movement of said original table and said optical system, said actually measuring means including means for measuring said time while said original table and said optical system are relatively and preliminarily moved by said moving means when only one moved image copy is to be formed, and means for measuring said time necessary for forming a succeeding moved image copy while a preceding moved image copy is formed when a plurality of moved image copies are to be formed in accordance with the same designated position or positions; and image forming means for forming a moved image copy based on the time actually measured by said actually measuring means.
Claim 3
Dependent Claim
99 words
An electrophotographic copying machine having an editorial function in accordance with claim 1, wherein said image forming means includes latent image forming means for forming a latent image on a photosensitive member, developing means for developing the latent image formed for said photoconductive member, transferring means for transferring a toner image developed by said developing means onto a paper, and controlling means for controlling timing when the toner image is to be transferred onto the paper by said transferring means based on the data of actually measured time and the position or positions designated by said position designating means.
Claim 4
Dependent Claim
50 words
An electrophotographic copying machine having an editorial function in accordance with claim 2, wherein said image forming means includes paper supplying means for supplying a paper to said transferring means, and said controlling means includes means for controlling timing when the paper is to be supplied to said transferring means.
Claim 5
Dependent Claim
67 words
An electrophotographic copying machine having an editorial function in accordance with claim 3, wherein said paper supplying means includes feeding means for feeding a paper toward said transferring means and stopping means for temporarily stopping the paper being fed by said feeding means, and said controlling means includes means for controlling timing when said paper is to be released from being temporarily stopping by said stopping means.
Claim 6
Dependent Claim
72 words
An electrophotographic copying machine having an editorial function in accordance with claim 4, wherein said actually measuring means includes counting means for counting a time from a timing when at least one of said original table and said optical system is started to be moved from a reference position or an origin position to a timing when a paper is started to be fed from said stopping means toward said photosensitive member.
Claim 7
Dependent Claim
69 words
An electrophotographic copying machine having an editorial function in accordance with claim 1, wherein said image forming means includes latent image forming means for forming a latent image on a photoconductive member and controlling means for controlling timing when the latent image is to be formed on the photosensitive member based on the data of actually measured time and the position or positions designated by said position designating means.
