A control method of a tape printing apparatus the method including performing a blade closing operation using a half cutter in a state in which rotation of a platen roller is stopped and subsequently performing a blade opening operation, causing a discharge feeding section to operate in a period from after the half cutter starts the blade opening operation and until the platen roller starts rotating, and determining presence or absence of a tape in a discharge feeding section based on a detection signal output from a discharge sensor during an operation of the discharge feeding section.

A sheet processing apparatus includes a sheet conveyor configured to convey a sheet, a processing tool configured to perform processing to the sheet, a tool contact separation device, a tool moving device, and a tool facing device. The tool contact separation device is configured to contact and separate the processing tool to the sheet. The tool moving device is configured to move the processing tool in a direction intersecting a conveyance direction of the sheet. 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.

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.

A cutting device, having a full-cutting assembly, a half-cutting assembly, and a cam, is provided. The full-cutting assembly includes a first cutting blade and a facing part to cut a tape fully through in a direction of thickness of the tape by rotating a first arm about a first shaft. The half-cutting assembly includes a second cutting blade and a supporting base to cut the tape partly in the direction of thickness by rotating a second arm about a second shaft. The cam is rotatable bidirectionally about a third shaft and has a cam face, on which a first pressing part to press the first arm and a second pressing part to press the second arm are arranged. A distance between the cam face and the second arm is smaller than or equal to a distance between the cam face and the first arm.

A housing is provided with a sheet ejection port for discharging sheet that passed through a printing unit upward. A cutting unit is arranged between the printing unit and the sheet ejection port and cuts the sheet by either a method of cutting the sheet in the entire width direction or a method of leaving the central portion of the sheet in the width direction. First protrusions and second protrusions protruding from the inner periphery of the sheet ejection port are provided at a plurality of locations along the width direction of the sheet. The first protrusion faces a first surface of the sheet and the second protrusion faces a second surface, which is the back surface of the first surface of the sheet. The first protrusion and the second protrusion are provided at positions deviated from each other in the sheet width direction and bend the sheet in an undulating shape in the width direction therebetween. Further, protrusion height of at least one of the first protrusions and the second protrusions in the central portion in the width direction of the sheet is lower than protrusion heights of the first protrusions and the second protrusions in other regions.

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 cutting mechanism for a printing apparatus, the cutting mechanism includes: a cutter including a cutting blade and a blade receiving member, the cutter being configured to cut at least part of a printing medium with the cutting blade while the blade receiving member is receiving a force from the cutting blade; and a support member provided to suppress deformation of the blade receiving member, wherein the blade receiving member is adjacent to and fixed to the support member.

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.

A cutter device, comprising: a first blade including a first cutting edge extending in a first direction; a second blade including a second cutting edge extending in a second direction; and a guide portion provided at a position anterior to the second blade in the second direction, wherein the second blade moves in the second direction to cut a recording medium while leaving a part thereof uncut, and when the second blade is located posterior, in the second direction, to a position where the second blade cuts the recording medium, at least a part of the guide portion is located to protrude farther in the first direction than the first cutting edge, or located at a same position as the first cutting edge.

A cutting device includes: a cutter blade configured to perform one of a half-cutting operation and a full-cutting operation with respect to a cut target; a cutter holder holding the cutter blade; a cutter cradle movable between a half-cutting position and a full-cutting position; and a cutter lever and a cutter cradle lever those operated by a user. When only the cutter lever is operated by the user, the cutter blade is moved so that the cutter blade and the cutter cradle at the half-cutting position perform the half-cutting operation with respect to the cut target. When both the cutter lever and the cutter cradle lever are operated by the user, the cutter cradle is moved to the full-cutting position and the cutter blade is moved so that the cutter blade and the cutter cradle at the full-cutting position perform the full-cutting operation with respect to the cut target.
