Abstract

Abstract There is a multi-color copying apparatus having image processing functions which can easily designate arbitrary areas when the trimming or masking is executed. This apparatus comprises: an area designating device to designate the first area of the original; a first developing device to develop the image of the first area in the first color; a second developing device to develop the image of the second area in the second color; and a control circuit for making the first developing device operative without making the second developing device operative in accordance with the designation of the first area and, after completion of the development of the image of the first area, making the second developing device operative without making the first developing device operative. The control circuit inhibits the operation of the first or second developing device by moving the first or second developing device to a position away from the photo sensitive drum, or by applying the bias voltage to the first or second developing device such that the toner from the inoperative developing device is not deposited onto the drum.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 123 words
An image processing apparatus comprising: first area designating means for designating an arbitrary area of an original, said first area designating means including a first designating system; second area designating means for designating an arbitrary area of an original, said second area designating means including a second designating system, wherein the first designating system is different from the second designating system; memory means for storing data representative of an area designated by said first area designating means and data representative of an area designated by said second designating means; wherein data stored in said memory means in response to actuation of one of said first and second area designating means is modifiable by the other of said first and second area designating means.
Claim 2
Dependent Claim 123 words
An image processing apparatus comprising: first area designating means for designating an arbitrary area of an original, said first area designating means including a first designating system; second area designating means for designating an arbitrary area of an original, said second area designating means including a second designating system, wherein the first designating system is different from the second designating system; memory means for storing data representative of an area designated by said first area designating means and data representative of an area designated by said second designating means; wherein data stored in said memory means in response to actuation of one of said first and second area designating means is modifiable by the other of said first and second area designating means.
