A cutting machine can be configured to set a cutting line with respect to a cutting material that is placed on a supporting platform, cut the cutting material along one cutting line that intersect with and changes direction at a second cutting line at a corner portion, leaving a part of the cutting material connected along a predetermined distance from a point of intersection of the corner portion, and cutting along the other cutting line so as to not leave a connected part, up to a predetermined distance from the point of intersection of the corner portion.

A medium-cutting device includes a medium-conveyance section to convey a medium in a medium-conveyance direction, a cutter to cut the medium conveyed by the medium-conveyance section, and a pushing part to push up a piece of the medium that is cut from the medium with the cutter.

A clamp includes first and second rising portions that rise from a base portion, a first extending portion extending along a first top surface of a table from the first rising portion, a second extending portion extending along a second top surface of the table from the second rising portion, a first clamp portion to urge a medium toward the first top surface, and a second clamp portion to urge the medium toward the second top surface. A gap located above a groove in the table is provided between the first clamp portion and the second clamp portion.

A cutter mechanism for a printer is provided. The cutter mechanism comprises a rotary cutter and a straight blade assembly. The rotary cutter may be mounted for rotation about a rotation axis and for translation across at least a portion of a width of a paper path perpendicular to the rotation axis. The straight blade assembly may be mounted for rotation about a shaft and adapted to cooperate with the rotary cutter. The straight blade assembly comprises a straight blade extending across the width of the paper path. A printer mechanism cover is mounted coaxially on the shaft so as to be movable between a closed position and an open position. A portion of the cover may impact the straight blade assembly when the cover is moved from the closed position to the open position, causing the straight blade to be moved away from the rotary cutter.

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.

Devices and methods for identifying categories or types of print media in image forming apparatuses are disclosed. In an example method print media are advanced in a feeding direction to reach a cutting position, a cutter is advanced in a cutting direction, perpendicular to the feeding direction to cut the print media, friction between the cutter and the print medium is measured, and the print media are identified based on the measured friction.

According to an example, a cutting module may comprise a carriage and a cutting blade, wherein the carriage may be capable of reciprocating movement along a cutting path. The carriage may be supported by a support structure and the cutting blade may have a fitting pin to engage with the carriage. During a first direction movement along the cutting path, the fitting pin may obtain a first cutting-edge angle. During a second direction movement along the cutting path, the fitting pin may obtain a second cutting-edge angle.

A cutting device includes: a movable blade; a moving mechanism moving the movable blade and having a first mechanism portion movable between a first operating position and a first non-operating position and a second mechanism portion movable between a second operating position and a second non-operating position; a first detecting portion and a second detecting portion detecting positions of the first mechanism portion and the second mechanism portion; and a controller configured to perform: setting, when one of the first detecting portion and the second detecting portion detects abnormally, updated positions of the first operating position and the second operating position or the first non-operating position and the second non-operating position. The updated positions are set based on detection result of another of the first detecting portion and the second detecting portion and are new start points of movement of the first mechanism portion and the second mechanism portion.

A cutter device including a transport unit for transporting a medium, a round blade configured to move, while rotating, in a width direction intersecting a transport direction in which the medium is transported, a fixed blade provided along the width direction, and a controller configured to control driving of the transport unit and a movement in the width direction of the round blade, in which the controller is configured, when the medium is cut by causing the round blade to move to a first direction of the width direction, to cause the round blade to move to a second direction being a direction opposite to the first direction while causing the round blade to rotate without causing the medium to move in the transport direction.

A cutter device includes a pair of pulleys including a first pulley and a second pulley, an endless belt spanning the pair of pulleys, a holder that holds a movable blade and moves in accordance with a movement of the endless belt, a first sensor configured to detect that a position of the movable blade is at a first position, and a second sensor configured to detect that the position of the movable blade is at a second position. The first sensor and the second sensor are disposed at positions overlapping with the holder in an up-down direction. The holder includes a first arm protruding toward the first position and a second arm protruding toward the second position. The first arm faces the first sensor when the holder is at the first position, and the second arm faces the second sensor when the holder is at the second position.
