Abstract: 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.

Abstract: 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.

Abstract: A printer includes a first blade configured to be movable between a standby position and a cutting position, a second blade configured to contact the first blade located in the cutting position, a drive mechanism configured to drive the first blade, and a first elastic member configured to pull the first blade located in the cutting position. When the first blade is located in the cutting position, the first elastic member pulls the first blade in a direction in which the first blade moves to the standby position, and pulls the first blade in a direction in which the first blade approaches the second blade.

Disposed to a carriage 21 carrying and inkjet head 22 and moving bidirectionally through a range of movement including the conveyance path of a cut-sheet paper S are: a panel member 78 able to protrude in the direction of carriage 21 movement; and a moving mechanism 126 causing the panel member 78 to protrude to the conveyance path of the cut-sheet paper S when the carriage 21 is at a standby position (home position) set in the range of carriage 21 movement.

Abstract: A cutter blade drive mechanism reliably returns a cutter blade from a forward position to a retracted position. A rotation transfer mechanism 34, which transfers rotation of a drive motor 31 to a drive gear 32, has a cutter blade return gear 50 that meshes with the drive gear 32, a compound gear (controller) 40 to which rotation from the drive motor 31 is transferred, and a transfer gear 51 that meshes with the compound gear 40 and the cutter blade return gear 50. While an intermittent teeth part 43a of the compound gear 40 and the transfer gear 51 are meshed, the cutter blade 21 moves to the forward position 21A.

Abstract: A cutter blade moving mechanism moves a cutter blade to a forward position by a low output drive motor without an urging member urging the cutter blade to the forward position where media is cut. The first cutter blade moving mechanism has a drive gear that moves the first cutter blade forward and back; a drive motor; and a compound gear to which rotation of the drive motor is transferred. The intermittent teeth part of the compound gear meshes with a transfer gear after turning the compound gear is started by drive power from the drive motor, completing a rotation transfer path. Because there is a delay between when driving the drive motor starts and when the path transferring rotation from the drive motor to the drive gear is completed, rotational kinetic energy is stored in the compound gear during this delay. The transfer gear can therefore be turned with greater drive power (rotational kinetic energy) when the compound gear and transfer gear mesh.

Abstract: A cutter has a first cutter blade moving mechanism 24 that moves a first cutter blade 21 reciprocally between a forward position 21A where recording paper 3 is cut and a retracted position 21B separated from the forward position 21A; and a second cutter blade moving mechanism 25 that moves a second-cutter blade 22 between a contact position 22A where the paper is cut in contact with the first-cutter blade 21 and a release position 22B separated from the contact position. The second cutter blade moving mechanism 25 sets the second cutter blade 22 to the release position 22B before the first cutter blade moving mechanism 24 moves the first cutter blade 21 from the forward position 21A to the retracted position 21B. Wear and noise can be prevented because the two cutter blades 21, 22 do not contact after cutting the recording paper 3.

Abstract: A cutter has a first cutter blade moving mechanism 24 that moves a first cutter blade 21 reciprocally between a forward position 21A where recording paper 3 is cut and a retracted position 21B separated from the forward position 21A; and a second cutter blade moving mechanism 25 that moves a second-cutter blade 22 between a contact position 22A where the paper is cut in contact with the first-cutter blade 21 and a release position 22B separated from the contact position.

Abstract: A printing device has a guide roller that guides a print medium in a conveyance direction; an intersect roller pair that holds the print medium guided by the guide roller between a first roller that rotates on an axis of rotation in the conveyance direction of the print medium and a second roller that rotates on an axis of rotation that intersects the axis of rotation of the first roller; a conveyance roller pair that conveys the print medium held by the intersect roller pair in the conveyance direction by a conveyance drive roller driven by a drive means and a conveyance follower roller that rotates with the conveyance drive roller; and a print unit that prints on the print medium conveyed by the conveyance roller pair.

Abstract: A printing head moving mechanism is configured to reciprocate a carriage equipped with a printing head between a printing position facing a recording medium and a retracted position retracted outside a printing region of the recording medium. In the printing position, the carriage is disposed at a downstream side of a transporting roller which is configured to transport the recording medium in a transporting direction of the recording medium. In the retracted position, at least a portion of the carriage is disposed at an upstream side of the transporting roller in the transporting direction of the recording medium. The carriage is configured to move between the printing position and the retracted position without interfering with the transporting roller.
