A roll body supporting device that rotatably supports a roll body includes a shaft member inserted into a core of the roll body, a shaft outer circumference member fixed to an outer circumference of the shaft member, a core support member that is inwardly in contact with and fits on the core, and a rotation support section that connects the shaft outer circumference member to the core support member and supports the core support member in a manner to be rotatable about the shaft member relative to the shaft outer circumference member.

A winding device is capable of easily moving a flange portion to a position corresponding to a width of a continuous medium. A winding device that winds a print medium, the winding device including a winding shaft, a winding core portion that is provided to be rotatable on the winding shaft and that winds a continuous medium, a first flange portion that is provided on the winding shaft to be movable in an extending direction of the winding shaft and that guides the continuous medium wound around the winding core portion in a width direction of the continuous medium, a flange-side engaging portion capable of moving integrally with the first flange portion, and a flange moving section that includes a cylindrical cam provided with a cam-side engaging portion that engages with the flange-side engaging portion and that moves the first flange portion to a plurality of flange positions.

A described example includes a ribbon cartridge having a first spool housing to receive a first spool. The ribbon cartridge further having a second spool housing to receive a second spool. The ribbon cartridge further having at least one frame member extending between the first spool housing and the second spool housing and a spool lock, wherein the spool lock is configured to engage at least one of the first spool or the second spool in response to the ribbon cartridge not being received within a ribbon positioning assembly.

A transport apparatus includes: a support unit that supports a roll; a drive unit that rotates the support unit; a cover configured to cover at least part of the support unit; and a load applying unit that applies a load to the support unit, wherein the cover is movable between a closed position at which the cover covers at least part of the support unit and an open position which is different from the closed position, and the load applying unit applies a large load to the support unit when the cover is located at the closed position compared with the case where the cover is located at the open position.

Technology enabling correctly detecting that paper has been delivered from a paper roll to the trailing end A printer has an inkjet head; a roll paper support; a delivery motor configured to rotate the roll paper supported by the roll paper support; a guide member configured to guide roll paper conveyed from the paper roll; and a detection switch disposed to a position where it detects the conveyed roll paper when the delivery point on the circumference of the paper roll moves to the part of the circumference of the roll on the same side of an imaginary line as the guide member; the delivery point being from which the conveyed roil paper separates from the roil when the paper roll turns; and the imaginary line being tangent to the guide member and passing through the center of the roll.

Provided is a printer that can appropriately handle a paper (media) wound into a roll with one end of the paper affixed to a core, when the trailing end of the paper is detected, the trailing end of the paper being attached to the winding core in multiple ways. The printer has: a roll paper support that supports the core of a roll of paper; a roll driver that turns the core and delivers the paper; a conveyance device that conveys the delivered paper; a tension detection switch that outputs a first detection value when tension produced on the paper delivered from the roll is greater than or equal to a threshold; and a controller that drives the roll driver in the direction delivering the paper when the output of the tension detection switch changes to the first detection value in response to rotation of the core.
