Abstract

Abstract An improved composite copying apparatus which is so arranged that, with an image area once set being memorized, a trimming mode and a masking mode are exchanged with respect to the same image area in each of the copying processes for two times, while the two copying processes can be continuously effected by a two-surface continuous copying device and a circulation transport device, whereby setting of modes, inputting of data, and setting of original documents and paper sheets may be eliminated at the second copying process for simplification of the composite copying operation.

Claims Analysis

Total Claims: 2
Claim 1
Independent Claim 158 words
A composite copying apparatus comprising: a trimming mode and a masking mode for effecting trimming and masking with respect to any desired area set within an image range of an original document; a two-surface continuous copying means, which bisects the image range in an original document scanning direction, for effecting an independent copying process continuously two times with respect to the respective ranges; circulation transport means for leading paper sheets completed for the copying process into the copying process section again through an intermediate storage portion; area memory means for memorizing the set area within the image range; continuous transport means for making said circulation transport means effective in the two copying processes of said two-surface continuous copying means; and continuous composite copying means for initiating the respective trimming mode and masking mode independently with respect to the area stored in said area memory means in each of the two copying processes of said two-surface continuous copying means.
Claim 2
Dependent Claim 158 words
A composite copying apparatus comprising: a trimming mode and a masking mode for effecting trimming and masking with respect to any desired area set within an image range of an original document; a two-surface continuous copying means, which bisects the image range in an original document scanning direction, for effecting an independent copying process continuously two times with respect to the respective ranges; circulation transport means for leading paper sheets completed for the copying process into the copying process section again through an intermediate storage portion; area memory means for memorizing the set area within the image range; continuous transport means for making said circulation transport means effective in the two copying processes of said two-surface continuous copying means; and continuous composite copying means for initiating the respective trimming mode and masking mode independently with respect to the area stored in said area memory means in each of the two copying processes of said two-surface continuous copying means.
