An ultraviolet (UV) light-emitting diode (LED) inkjet printer includes a printing member for performing printing on a surface of a substrate, a carrying member configured to continuously pull the substrate so that the substrate can be conveyed forward from the printing member, a supporting platform and a cutting member. The supporting platform is provided in front of the carrying member to support the substrate conveyed from the carrying member. The cutting member is provided above the supporting platform, and includes a guide rail and a cutter. The guide rail extends in a direction orthogonal to a direction in which the substrate is conveyed, and extends at least across an area of the supporting platform for supporting the substrate. The cutter is carried on the guide rail, and is movable along the guide rail. The cutter is configured to abut against and cut the substrate on the supporting platform.

A printing apparatus comprises a conveyance control unit which controls conveyance of printing sheets so that a trailing edge of a preceding sheet as a printing sheet precedingly fed from the stacking unit and a leading edge of a succeeding sheet as a printing sheet succeedingly fed from the stacking unit overlap each other; and a skew correction unit which performs skew correction of the succeeding sheet while the succeeding sheet overlaps the preceding sheet by the conveyance control unit. The skew correction unit makes the leading edge of the succeeding sheet abut against the conveyance roller during a time from an end of a last line feed operation by the conveyance roller for printing on the preceding sheet by the printing unit to start of a next conveyance operation.

A printer includes a rolled paper holder that accommodates rolled paper wound with recording paper having a recording surface and an adhesive surface provided on a side opposite to the recording surface, a platen roller that comes into contact with the adhesive surface and draws and feeds the recording paper from the rolled paper, a thermal head that performs printing on the recording surface, and a first guide portion that comes into contact with the recording surface and guides the recording paper, and the first guide portion has a first friction reduction portion that reduces a friction force generated between the recording surface and the first guide portion.

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.

A media feeding system comprises a driver configured to rotate a media roll in a first direction; a vacuum roller positioned in a media feed path and configured to rotate in the first direction; and a media end detecting sensor positioned in the media feed path, the media end detecting sensor being configured to detect a leading edge of the media; wherein the driver rotates the media roll in a second direction opposite the first direction in response to the sensor detecting the leading end of the media.

A printer includes: a conveyor that performs a forward-conveyance operation for conveying a printing medium downstream in a conveying direction and a backward-conveyance operation for conveying the printing medium upstream in the conveying direction; a printing device; a roller provided downstream of the conveyor in the conveying direction; an opposed member opposed to the roller; a moving mechanism that moves a moving member, which is one of the roller and the opposed member, between (i) a first position at which the printing medium is nipped between the moving member and the other of the roller and the opposed member and (ii) a second position at which the moving member is separated from the printing medium; and a controller that executes a first conveyor-backward-conveyance processing for controlling the conveyor to perform the backward-conveyance operation in a state in which the moving member is located at the second position.

A meandering control device includes: a detector configured to detect a position of an edge of a web being conveyed in a width direction of the web; a corrector configured to correct a position of the web being conveyed in the width direction; and a controller including a digital filter configured to perform filtering on a position signal indicating the position of the edge detected by the detector to attenuate a noise component. The controller is configured to drive the corrector to correct the position of the web in the width direction based on the position signal after the filtering.

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.

A roll paper printer includes a case that includes an accommodation section configured to accommodate roll paper, a cover that rotates about a cover hinge located below the case, and opens and closes the accommodation section, in which the cover includes a cover guide configured to guide the roll paper, the cover guide includes a first cover guide, a second cover guide, and a third cover guide disposed toward the cover hinge, the first cover guide and the second cover guide are configured to come into contact with the roll paper having a first diameter, whereas the third cover guide does not come into contact with the roll paper having the first diameter, when the cover is closed, and the third cover guide is inclined downward toward the accommodation section, and is configured to guide the roll paper to the accommodation section, when the cover is opened.

A technique capable of inhibiting a decrease in work efficiency at the time of replacing a roll sheet is to be provided. The present invention includes: a supply unit configured to support, in a rotatable manner, the roll sheet to which a shaft member is attached and supply a sheet unwound from the roll sheet; a base part arranged above the supply unit and configured to be capable of supporting the roll sheet; and a guide part configured to guide the roll sheet to which the shaft member is attached to the supply unit via the shaft member, wherein the shaft member is inserted into the guide part by moving the roll sheet to which the shaft member is attached from the base part.
