Patent ID: 8090308

Claim:
A continuous paper feed device comprising: a paper feed unit that feeds continuous paper to an image output part; a slack forming unit that forms a slack of continuous paper on a paper transport path through which the continuous paper is fed by the paper feed unit; a detecting unit that detects a remaining amount of continuous paper; a cutting unit that cuts the continuous paper; and a cutting controller that controls the cutting unit to cut the continuous paper during a time taken to tighten the slack formed by the slack forming unit, when paper whose length is more than a predefined value which has been set beforehand is transported, and if the remaining amount of paper detected by the detecting unit is equal to or more than a threshold value, the cutting controller performs one mode of control operation including reducing a length of a slack formed by the slack forming unit and transporting the continuous paper, followed by forming a slack again by the slack forming unit and cutting the continuous paper during a time taken to tighten the slack, or if the remaining amount of paper detected by the detecting unit is less than the threshold value, the cutting controller performs another mode of control operation including transporting the continuous paper with a slack formed thereon by the slack forming unit and cutting the continuous paper during a time taken to tighten the slack.
