Abstract: A roll sheet, in which a continuous sheet is wound in a roll form, is caused to rotate in a forward direction to supply the sheet to a printing unit. First and second sensors are arranged at positions facing an outer circumferential surface of the roll sheet and deviated in an axis line direction of the roll sheet. Outputs of the first and second sensors are changed in accordance with a distance to a sheet of the roll sheet. A rotation direction of the roll sheet is switched from a forward direction to a reverse direction on the basis of the outputs of the first and second sensors while the roll sheet is being rotated in the reverse direction.

Abstract: An image forming apparatus includes: a housing; a feed tray insertable into and removable from the housing and accommodating a sheet-shaped medium; a feed roller feeding the sheet-shaped medium; an image forming device; and a movement mechanism. The feed tray includes: a first accommodation portion accommodating a roll body, a first sheet-shaped medium being rolled in a roll shape as the roll body; and a second accommodation portion accommodating a second sheet-shaped medium which is shorter than the first sheet-shaped medium. The movement mechanism moves to a first position where the feed roller contacts the first sheet-shaped medium unrolled from the roll body accommodated in the first accommodation portion and a second position where the feed roller contacts the second sheet-shaped medium accommodated in the second accommodation portion.

Abstract: A feeding apparatus includes a roll support unit configured to rotatably support a roll sheet which is a sheet wound into a roll form, a drive unit configured to rotate the roll sheet in a first rotation direction for feeding the sheet into a conveyance path and a second rotation direction, an abutment portion provided so as to be capable of abutting against an outer peripheral surface of the roll sheet at a first position, and a rotation member configured to abut against the outer peripheral surface at a second position. The rotation member at the second position does not rotate with the roll sheet when the roll sheet is rotated in the first rotation direction, and rotates with the roll sheet when the roll sheet is rotated in the second rotation direction.

Abstract: An expansible chuck for holding hollow cylindrical cores used for winding and unwinding sheet material. A portion of the chuck body nearest the flange is stepped up so that the diameter of the chuck near the flange is slightly larger than the diameter of the rest of the chuck. The stepped up portion centers the chuck within the core which helps the expanding elements to uniformly grip the core.

Abstract: A conveying apparatus includes: a conveying unit configured to convey a sheet in a conveyance direction along a conveyance path; a sheet holder arranged upstream in the conveyance direction from the conveying unit to rotate around an axis, the axis extending in a first direction intersecting with the conveyance direction; a tensioner arranged between the sheet holder and the conveying unit in the conveyance path and configured to apply tension to the sheet with the sheet being curved; and a first side guide attached to the tensioner and having a first guide surface, the first guide surface spreading along the conveyance direction and a second direction intersecting with the first direction. The tensioner includes an oblique roller configured to guide the sheet to the first guide surface.

Abstract: A print medium feeding device removes a second sheet from a print medium that is in a state in which a first sheet, the second sheet, a the third sheet are superposed, superposes the first sheet and the third sheet, and feeds the first sheet and the third sheet to a printing device. The print medium feeding device includes: a first roller configured to come into contact with the third sheet and to be driven to rotate by movement of the third sheet; a second roller configured to come into contact with the first sheet and to be driven to rotate by movement of the first sheet; a roll-up member disposed upstream of the first roller and configured to roll up the second sheet; and a transmission mechanism configured to transmit a rotational force of the first roller to the roll-up member.

Abstract: An electric stretch film dispenser includes a frame and a power unit. The frame has a top seat and a bottom seat. The top seat and the bottom seat are jointly provided with a film mounting unit and a film dispensing unit. The film dispensing unit has a first roller and a second roller. The first roller is connected with a first power drive unit. The first power drive unit is configured to drive the first roller to rotate. When in use, the film of a film roll is pulled due to different rotational speeds of the first roller and the second roller. Thereby, the electric stretch film dispenser can automatically generate tension when used, so it can be used to pack articles at different heights. The electric stretch film dispenser facilitates the application of the film and increases the tension of the film.

Abstract: A sheet feeding device includes a support that detachably supports a roll, a rotation driver that rotates a spool, a guide including a facing portion and a guide portion, a support shaft that swingably supports the guide, a biasing member that presses the guide, a sensor that retractably projects from the facing portion and outputs a detection signal, a roller that contacts an outer circumferential surface of the roll, and circuitry that controls the rotation driver. The circuitry determines a passing time based on a first change rate and a second change rate, and causes the rotation driver to rotate the spool by a predetermined angle in a winding direction, from the passing time, to position a leading end of a continuous sheet at a feeding start position, and rotates the spool in the feeding direction to feed the continuous sheet from the feeding start position along the guide portion.

Abstract: A sheet supplying apparatus, which is capable of winding a sheet tightly, includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, and a contact body that presses the outer circumferential surface. Before the sheet is fed, in a state in which the contact body presses the outer circumferential surface, the driving unit causes the roll to continuously rotate in the second direction until a detection cycle of the leading end portion by the sensor is less than a predetermined value.
