Abstract
Abstract A feed control device includes a feeder for feeding sheet from copy mediums to a predetermined position, a device for forming an image on or from a copy medium fed by the feeder, and a controller for controlling the driving of the feeder with the copy medium being present at the feeder in order to complete the feed of the copy medium by the inertia force of the feeder.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
46 words
A feed control device comprising: means for feeding sheet mediums to a predetermined position; control means for de-energizing the driving force to said feed means, while a sheet medium is engaged therein, wherein inertia forces of the feed means complete the feed of said sheet medium.
Claim 2
Dependent Claim
46 words
A feed control device comprising: means for feeding sheet mediums to a predetermined position; control means for de-energizing the driving force to said feed means, while a sheet medium is engaged therein, wherein inertia forces of the feed means complete the feed of said sheet medium.
Claim 3
Dependent Claim
37 words
A feed control device according to claim 1, wherein said control means detects the trailing end of the medium by detector means provided upstream of said feed means to thereby stop the driving of said feed means.
Claim 4
Dependent Claim
26 words
A feed control device according to claim 1, wherein said control means stops the driving of said feed means a predetermined time after it is started.
Claim 5
Dependent Claim
25 words
A feed control device according to claim 1, wherein said feed means comprises a roller and the feed is completed by the inertia force thereof.
Claim 6
Dependent Claim
