A recording device includes a conveyance mechanism, a recording mechanism, a rotational mechanism of a plurality of take-up spindles, and a control unit. The conveyance mechanism is configured to convey a recording medium intermittently in a conveyance direction. The recording mechanism is configured to record by reciprocatingly scanning a recording head in a direction that intersects with the conveyance direction. The rotational mechanism is configured to take up the recording medium. The control unit is configured to control the conveyance mechanism and the rotational mechanism to substantially synchronize conveying of the recording medium by the conveyance mechanism and taking-up of the recording medium by the rotational mechanism.

A method is for notifying information of a remaining amount of a recording medium in a recording apparatus including a delivery section that rotates and delivers a roll-shaped recording medium, a transport belt that transports the recording medium delivered from the delivery section, and a slack sensor that detects a slackened state in the recording medium delivered from the delivery section to the transport belt. The method includes notifying the information of the remaining amount of the recording medium if the slack sensor detects a lack of slack of the recording medium in a period of a first time or more.

A method and an apparatus for stabilizing the position of a sheet-like element made of hard brittle material during transportation thereof along a transport path is provided in which the element is guided through a roller chicane having three rollers.

A printer 1 has a movable member 27 that can move following change in the tension on recording paper 3 between a roll paper compartment 7 and a conveyance mechanism 12 on the paper conveyance path 8. When recording paper 3 of which the end is glued to the core 2a of a paper roll 2 runs out, the tension on the recording paper 3 rises and the movable member 27 goes to a tension-side error determination range E1 in its range of allowable movement E0. When the movable member 27 is in the tension-side error determination range E1, the time the movable member 27 remains in the tension-side error determination range E1 is counted, and if this measured time exceeds an error determination time, an error detection unit 38 detects an error. No-paper errors can therefore be detected without using a dedicated sensor.

A sheet feeding apparatus includes a tray configured to support a sheet, a lifting unit configured to raise and lower the tray, an air blowing unit configured to blow air to a side edge of the sheet supported by the tray to float the sheet, an attraction and conveyance unit configured to execute a feeding operation of attracting and feeding the floated sheet, an upper surface detection unit configured to detect a lower state where an upper surface of the sheet is below a detection position, and a control unit configured to control the lifting unit and the attraction and conveyance unit. The control unit is configured to execute a mode in which the tray is raised by the lifting unit for a second time longer than a first time in which the lower state is detected.

A paper folding machine includes: a conveyor belt configured to transport a sheet; a stopper configured to abut against the leading end of the sheet to stop the sheet; a knife having an elongated shape and configured to move onto a folding position of the sheet stopped by the stopper; a guide made of a rigid material and configured to hold the sheet between the conveyor belt and the guide and press the sheet transported to the stopper; and a lifting mechanism configured to adjust the clearance between the guide and the conveyor belt.

A roll transfer assembly for a web processing system includes a support beam configured to be mounted to a frame. The assembly includes a segmented roll assembly mounted to the support beam and includes a first and second end segments and a central segment positioned between the first and second end segments. The assembly includes a first transfer roll positioned between the first end segment and the central segment and a second transfer roll positioned between the second segment and the central segment. The assembly includes an actuation assembly that includes a first drive system configured to translationally move the first transfer roll and the second transfer roll. A second drive system is configured to move the roll transfer assembly relative to the frame.
