The tool facing device has an opposing face and is disposed at a position at which the tool facing portion faces the processing tool via the sheet. The tool facing device is configured to move to change the tool facing portion in accordance with a relative moving direction of the sheet with respect to the processing tool when the processing tool performs the processing to the sheet.

A printing apparatus is able to perform partial cutting in which a portion of thermal paper remains uncut and full cutting in which the thermal paper is completely cut, and the printing apparatus includes a movable blade, a plate, and a driven gear. The plate includes a guide groove, the movable blade includes a guide shaft, the guide groove includes a first side and a second side, and the second side includes a certain portion extending in a direction away from the first side. When the driving gear rotates in a first rotational direction, the guide shaft changes a position with respect to the guide groove along the first side to perform the partial cutting, and when the driving gear rotates in a second rotational direction, the guide shaft changes the position with respect to the guide groove along the second side to perform the full cutting.

A tape includes: a sheet; first and second media arranged adjacent to each other in a longitudinal direction of the sheet, spaced from each other, and peelably stuck to the sheet; a first separating line extending between first and second ends of the sheet in a widthwise direction between the first and second media; and a second separating line formed at a portion of the sheet which is located between a center position of the second medium in the widthwise direction and a first end of the second medium in the widthwise direction. The second separating line is formed at at least a portion of the sheet which is located between first and second ends of the second medium in the longitudinal direction. Each of the first and second separating lines includes a portion formed through or cut in the sheet in a thickness direction.

A printing system for printing images onto a medium supplied as feed-stock, said system comprising a printer, a control computer and data inputting means, a printer head, a cutter, at least one rewinder and a taper; the print head for printing individual work-pieces onto the medium; the cutter for cutting the medium into individual work-pieces, and the at least one rewinder for rewinding the work-pieces into coreless-rolls, and the taper comprising a tape dispenser and printer for printing identifying data onto a piece of tape applied to fasten each coreless roll closed wherein the cutter and the printing of the tape is controlled by the control computer, wherein the cutter is configured to section the work-piece from the feedstock after it has started to be fed into the rewinder.

Provided is a tape printing apparatus including a half cutter and a mounting portion lid. The half cutter has a half-receiving portion and a half-movable portion, the half-movable portion includes a half-movable blade and comes into contact with or separates from the half-receiving portion, a first side, which is one side of the half-movable blade in a blade length direction, is open between the half-receiving portion and the half-movable portion, and the mounting portion lid opens and closes a cutter mounting portion on which the half cutter is mounted. The mounting portion lid is provided with a lid-side half-receiving support portion that supports at least one of an end on the first side of the half-receiving portion and an end on the first side of a third frame portion that supports the half-receiving portion pressed by the half-movable portion when the mounting portion lid is closed.

Provided is a tape cutter including a full-receiving portion, a full-movable portion that comes into contact with or separates from the full-receiving portion, a full-pressing portion that presses the full-movable portion, and a full second lever portion to which the full-pressing portion is fixed. The full-pressing portion has a full first pressing portion that presses a full first pressing target portion of the full-movable portion toward the full-receiving portion so that the full-movable portion approaches the full-receiving portion, and a full second pressing portion that engages with a full second pressing target portion of the full-movable portion and pulls the full second pressing target portion toward a side opposite to the full-receiving portion so that the full-movable portion separates from the full-receiving portion, and the full first pressing portion and the full second pressing portion are overlapping with the full second lever portion in a feed direction of the tape.

A cutter unit includes a cutter holder, a cradle, a cutter lever, a cradle lever, and a transmitting portion. The cradle faces the cutter holder and movable between a full-cut position and a half-cut position. The cutter lever is configured to be contactable with the cutter holder. The cradle lever is configured to be contactable with the cradle. The transmitting portion is configured to move the cutter lever and the cradle lever in interlocking relation therebetween. The transmitting portion is configured to shut off transmission of movement of the cutter lever to the cradle lever in accordance with only operation to the cutter lever out of the cutter lever and the cradle lever while the transmitting portion is configured to transmit movement of the cradle lever to the cutter lever in accordance with only operation to the cradle lever out of the cutter lever and the cradle lever.

A half cutter includes a blade, a blade holder to which the blade is fixed, and a blade receiving member which the blade approaches to or departs from. The blade holder has a pressure receiving portion that receives a pressing force which presses the blade holder against the blade receiving member, and a transmission section that transmits the pressing force received by the pressure receiving portion to both end portions of the blade in an extending direction of a blade edge of the blade.

A half cutter includes a blade, a blade holder to which the blade is fixed, a blade receiving member which the blade approaches to or departs from, a blade receiving holder to which the blade receiving member is fixed, a spacer which is provided to at least one of the blade and the blade receiving member and generates a gap between the blade and the blade receiving member when the blade approaches the blade receiving member, and a fixing member that fixes the spacer to at least one of the blade holder and the blade receiving holder.

A printing apparatus includes a printing unit that performs printing on a print medium with a sheet shape, a medium feeding unit and a medium winding unit that conveys the print medium in a predetermined conveyance direction, a controller that controls the printing unit, the medium feeding unit, and the medium winding unit, and a shaft that winds the printed print medium. The controller includes a cutting position determination unit that determines a cutting position to cut and separate the print medium in the width direction upstream by a predetermined length from the end of the image of the first print surface in the conveyance direction, and the cutting position determination unit determines the cutting position so as to cut upstream from the end with an increase in the circumferential length of the print medium wound around the shaft.
