摘要： 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.

摘要： Provided are a carriage structure capable of preventing a carriage from contacting a side edge of a print medium, without requiring a discharge roller and facilitating reducing device size, and a printer having the carriage structure. 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.

摘要： 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.
摘要翻译： 切割刀片移动机构通过低输出驱动马达将切割刀片移动到向前位置，而不需要将切割刀片推动到介质被切割的向前位置的推动构件。 第一刀片移动机构具有使第一切割刀片向前和向后移动的驱动齿轮; 驱动电机; 以及传动驱动马达的旋转的复合齿轮。 复合齿轮的间歇齿部分与传动齿轮啮合后，通过来自驱动马达的驱动力开始复合齿轮的起动，从而完成旋转传递路径。 由于在驱动驱动电动机起动之间和当从驱动电动机转动到驱动齿轮的路径完成的路径之间存在延迟时，在该延迟期间，旋转动能被存储在复合齿轮中。 因此，当复合齿轮和传动齿轮啮合时，传动齿轮可以以更大的驱动力（旋转动能）转动。

摘要： 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 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. When the intermittent teeth part 43a and the transfer gear 51 are not meshed and the compound gear-side protrusion 44b of the compound gear 40 is in contact with a cutter blade return protrusion 50b of a cutter blade return gear 50, the cutter blade return gear 50 rotates in unison with the compound gear 40, the drive gear 32 turns in the opposite direction, and the cutter blade 21 returns to the retracted position 21B.

摘要： 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.

摘要： A platen support mechanism of a printer moves a platen unit of the printer. When moving the platen unit from a closed position to an open position, the platen support mechanism of the printer first moves the platen unit along a straight first path, and then moves the platen unit along a curved second path. A posture of the platen unit is held constant during this time by a six joint linkage mechanism.
