  • Publication number: 20120032021
    Abstract: A roll medium holding unit is disclosed that includes a core part configured to be inserted in a core pipe of a roll medium; and plural diameter-increasing members configured to be variably arranged at corresponding first positions provided along a periphery of the core part and arranged at corresponding second positions provided away from the core part. The roll medium holding unit is capable of being set in a first holding state where the diameter-increasing members arranged at an outer peripheral surface of the core part support the roll medium with the diameter-increasing members arranged at the corresponding first positions and capable of being set in a second holding state where the core part of a holding member supports the roll medium with the diameter-increasing members arranged at the corresponding second positions.

  • Publication number: 20110229242
    Abstract: A rolled paper driving apparatus includes supporting rollers that support rolled paper in such a manner that an axis line of the rolled paper extends between the supporting rollers, the rolled paper having a core pipe in a shape of a pile; a driving roller that is pressed onto an inner circumferential surface of the core pipe of the rolled paper and gives force to rotate the rolled paper; a driving force transmission part that rotates the driving roller; and a pressing force adjustment part that adjusts a state of the driving roller being pressed onto the inner circumferential surface of the core pipe of the rolled paper. The driving roller is disposed in the inside of a triangle that has vertexes corresponding to the supporting rollers and a center of the rolled paper, respectively.

  • Publication number: 20110211210
    Abstract: An image forming apparatus including an image reading unit disposed in an upper portion of the image forming apparatus, an image forming unit disposed below the image reading unit to form an image on a sheet fed from a sheet roll, a pair of flange members attached to both lateral ends of the sheet roll in a width direction of the sheet roll, a sheet roll supporter disposed below the image reading unit in a rear portion of the image forming apparatus to support the sheet roll, an opening through which the sheet roll is set to the sheet roll supporter, and a guide assembly provided at upper and lower parts of the opening to position at least one of the pair of flange members attached to the sheet roll in the width direction to guide the sheet roll to the sheet roll supporter.

  • Publication number: 20110114691
    Abstract: A sheet-supply device internally defining a supply route through which to supply a sheet. The sheet-supply device includes a supply member to supply the sheet from a rolled long sheet, a guide member to guide the sheet to the supply member, provided upstream in a direction in which the sheet is moved to the supply member and, movable between a guide position at which the sheet is guided to the supply member and an escape position at which the guide member is away from the supply route of the sheet.

  • Publication number: 20110063391
    Abstract: A sheet feeder for transporting a sheet unreeled from a roll includes a feed roller to unreel the sheet from the roll, a registration roller to transport the sheet unreeled by the feed roller to the image forming unit, a pressure roller pressing against the registration roller, forming a registration nip together with the registration roller, a movable sheet guide to guide the sheet to the registration roller, disposed between the feed roller and the registration roller in a sheet conveyance path, a support member to movably support the movable sheet guide relative to an apparatus body in which the sheet feeder is disposed, and a bias member to bias the sheet guide toward the sheet. The movable sheet guide wraps more of the sheet around the registration roller as a degree of tension of the sheet increases by moving against a bias force exerted by the bias member.

  • Publication number: 20100327515
    Abstract: A roll-sheet feeding device having a roll sheet wound in a roll to feed a portion of the roll sheet to an image forming unit, includes a progressive mechanism to transmit a drive force from a drive source to transfer the portion of the roll sheet from the roll in a progressive direction, a roll-sheet drive mechanism to receive the drive force transmitted via the portion of the roll sheet transferred in the progressive direction, a rewinding mechanism to transfer the portion of the roll sheet in a direction opposite to the progressive direction via the roll-sheet drive mechanism to rewind the roll sheet, and a regenerating mechanism to obtain the drive force from the roll-sheet drive mechanism and transmit the obtained drive force to the progressive mechanism to regenerate the transmitted drive force as another drive force in addition to the drive force from the drive source.
