Abstract
Abstract In an image making system for forming a combined image on a recording medium on the basis of an optical image having scanned an original resting on an original carriage and an information image provided by a light beam controlled by an information signal, an optical image application termination timing is made constant with the scanning termination side of the original carriage as the original placement standard, and an optical image application start timing and an information image application timing are set on the basis of said standard to thereby effect the control of image making.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
176 words
An image forming apparatus capable of forming a combined image including an image corresponding to an original and an image corresponding to an information signal comprising: a movable member; an original supporting means; scanning means movable relative to said original supporting means for scanning the original; an adjusting member to set the position of the rear end of the original, the adjusting member being mounted on said original supporting means at a position along the side of which the scanning of the original by said scanning means is completed; conveying means to convey a transfer material toward said photosensitive member; variable setting means for setting a first time during the imaging operation for initiating the projection of light corresponding to said information signal to said photosensitive member, and for setting a second time, which is later than said first time, for initiating the projection of light corresponding to the original to said photosensitive member; and setting means for setting a time for initiating the movement of said conveying means in correspondence with the said first time.
Claim 2
Dependent Claim
176 words
An image forming apparatus capable of forming a combined image including an image corresponding to an original and an image corresponding to an information signal comprising: a movable member; an original supporting means; scanning means movable relative to said original supporting means for scanning the original; an adjusting member to set the position of the rear end of the original, the adjusting member being mounted on said original supporting means at a position along the side of which the scanning of the original by said scanning means is completed; conveying means to convey a transfer material toward said photosensitive member; variable setting means for setting a first time during the imaging operation for initiating the projection of light corresponding to said information signal to said photosensitive member, and for setting a second time, which is later than said first time, for initiating the projection of light corresponding to the original to said photosensitive member; and setting means for setting a time for initiating the movement of said conveying means in correspondence with the said first time.
Claim 3
Dependent Claim
