摘要： The present invention relates to a roll paper conveyer and an image reading device. Flange components (130) are configured at two ends of a paper roll (110) formed by the reeling paper (111). The outer diameters of the flange components (130) is smaller than the outer diameter of the paper roll (110) in maximum reeling so that the flange components (130) are rotatablely supported on the flange supporting platforms (140). A strip component (180) is provided as a rollback device, which contacts with the surface of the paper roll (110) and causes the paper roll (110) to rotate backwards with a friction at the surface of the paper roll (110). A belt component (180) is provided on three rolls (150,160,170) so that the position of one roll (170) in three rolls can be changed. According to the residual amount of paper, the pushing force of the belt component (180) to the paper roll (110) is adjusted to appropriate. The user can change the roll paper easily and simultaneously the roll paper can be rolled back stably.

摘要： PROBLEM TO BE SOLVED: To provide a paper feeder for improving a carrying quality by optimizing back tension, by attaining the long service life by optimizing the sliding quantity of a flange, a relay roller and a rewinding roller. SOLUTION: This paper feeder has the flange 1 having a smaller diameter than the maximum diameter of installable roll paper 2, a flange receiving base 3 for supporting the rotation of the flange 1, the rewinding roller 4 for winding the roll paper 2 on a roll by reversely rotating the flange 1, the relay roller 5 for transmitting the drive of the rewinding roller 4 to the flange 1, a paper feeding roller 6 for imparting a normal rotation to the roll via the roll paper 2 by gripping and sending out the roll paper 2 when progressively sending the roll paper 2, a driving system, a motor and a control system of these for transmitting the driving to paper feeding-rewinding respective rollers. The rotating speed of the flange 1 is made variable when sending out and rewinding the roll paper 2 in response to the residual quantity of the roll paper 2. COPYRIGHT: (C)2010,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To reduce driving electric power consumed by driving when performing intermittent carrying operation in a state of applying predetermined tension to roll paper. SOLUTION: The problem is solved by including a plurality of carrier rollers for carrying continuous paper by the predetermined length by independent driving, a guide plate positioned between the plurality of carrier rollers and applying the predetermined tension to the paper carried between the plurality of carrier rollers, a paper feeding roller positioned upstream of a carrying passage of the plurality of carrier rollers and feeding the paper by the independent driving, and a sagging control means for forming sagging in the paper existing between the first carrier roller and the paper feeding roller when stopping a first carrier roller positioned on the upstream side of the carrying passage among the plurality of carrier rollers and eliminating the sagging up to a second carrier roller and the paper feeding roll of the paper when driving the second carrier roller positioned on the downstream side of the carrying passage among the plurality of carrier rollers.
