Abstract: A recording apparatus includes a recording unit that performs recording by ejecting ink onto a medium; a pump unit that sucks a waste liquid discharged from the recording unit in a maintenance of the recording unit; a wall portion; a body in which the recording unit, the pump unit, and the wall portion are provided; and a housing in which the body is housed. The body is provided in the housing in such a way as to be changed in position between a closed position and an open position in a depth direction. The closed position is a position where the body is housed in the housing. The open position is a position where the body protrudes from the housing and where a part of the body is exposed from the housing. The wall portion is provided at a position of hiding at least a part of the pump unit exposed when the body is located at the open position.

Abstract: A printing device includes: a printing unit printing on a recording paper; a feeder unit that has a roller rotating in a first direction about a shaft and feeding the recording paper, and a motor rotating the shaft; a detection unit detecting a rotation of the shaft in the first direction and a rotation thereof in a second direction opposite to the first direction; and a control unit controlling the feeder unit, based on the rotation of the shaft detected by the detection unit. The control unit causes the motor of the feeder unit to rotate the shaft in the first direction and then stop the shaft, and subsequently causes the motor to rotate the shaft in the first direction before the printing unit prints, based on the rotation of the shaft in the second direction detected by the detection unit.

Abstract: A recording apparatus includes a recording unit that performs recording on a medium, a body in which the recording unit is mounted, a housing configured to house the body, and a holding portion configured to hold the body at a predetermined position with respect to the housing. The predetermined position includes a closed position, a first open position, and a second open position. The closed position is a position at which the body is housed inside the housing. The first open position is a position at which the body protrudes from the housing in a first displacement direction of a displacement direction intersecting with a vertical direction by a first distance. The second open position is a position at which the body protrudes from the housing in the first displacement direction by a second distance longer than the first distance.

Abstract: A recording device includes a recording unit configured to perform recording on a medium, a reversing unit configured to bend and reverse the medium on which recording was performed by the recording unit and that is transported along a transport path and guide the medium toward a recording unit side, a base portion disposed below the reversing unit, a first frame fixed to the base portion and disposed on a side of a first side surface of the reversing unit to hold the reversing unit, a second frame fixed to the base portion and disposed on a side of a second side surface different from the first side surface to hold the reversing unit, and a coupling portion coupling the first frame and the second frame to each other at a position away from the base portion.

Abstract: A switching portion is configured to change in position between a first switching position and a second switching position, at which the switching portion protrudes more from a bottom surface of a housing than at the first switching position. The first switching position is a position at which the switching portion is located in a state of being in contact with the installation surface when the housing is installed on the installation surface. The second switching position is a position at which the switching portion is located when the housing is not installed on the installation surface. The switching portion does not restrict a change in position of a body in a position-change direction when located at the first switching position and restricts the change in position of the body in the position-change direction when located at the second switching position.

Abstract: A printing apparatus includes: a roll sheet container that contains a roll sheet around which a recording sheet is wound; a first sheet guide that makes contact with a first surface of the recording sheet; a second sheet guide that makes contact with a second surface of the recording sheet; and a transport roller that transports the recording sheet. The first and second sheet guides are disposed so as to face each other to form a sheet route along which the recording sheet is to pass. The transport roller transports the recording sheet that passed along the sheet route. The second sheet guide includes: a projection that protrudes toward the roll sheet container; and a pushing section that extends from the projection along an outer circumference of the roll sheet and in a direction away from the first sheet guide.

Abstract: A cutter can move a movable knife by two cutter drive gears without the movable knife becoming skewed. The cutter 10 of a mobile printer 1 has a fixed knife 11, and a cutter drive mechanism 32 that moves the movable knife 31 straight to and away from the fixed knife 11. The cutter drive mechanism 32 has two cutter drive gears 51 that are driven synchronously, and a cutter drive plate 54 disposed between the two cutter drive gears 51 and the movable knife 31. The two cutter drive gears 51 cause the cutter drive plate 54 to move to and away from the movable knife 31 on a longitudinal axis Y (direction of travel), thereby moving the movable knife 31 to and away from the cutter drive plate 54. If the cutter drive plate 54 becomes skewed when the two cutter drive gears 51 move the cutter drive plate 54, the guide mechanism 81 prevents skewing of the movable knife 31.

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: In connection with a printer, a platen roller is configured to rotate in a first direction and to transport a recording medium. A print head facing the platen roller includes a head body portion having a printing portion to perform printing on the recording medium when the platen roller transports such medium. A supporting mechanism supports the head body portion, presses the head body portion against the platen roller, and moves the head body portion by rotation of the platen roller. An urging unit urges the head body portion toward the platen roller. When the platen roller rotates in a second direction opposite to the first direction, the supporting mechanism moves the head body portion by the rotation of the platen roller, and a contact position of the head body portion with respect to the platen roller is shifted while maintaining the head body portion pressed against the platen roller.

Abstract: The platen bearings attached to the shaft end parts of the removable platen roller are pressed by lock levers to bearing insertion slots that are formed in the main frame of the thermal printer so that the positions of the platen bearings are determined by two points on the main frame and one point on the lock lever.

Abstract: A thermal printer avoids or reduces difficult to correct problems caused by recording paper that has passed the printing position leaving the paper transportation path. A printing mechanism has a head mounting plate that carries a line thermal head, a front guide plate disposed downstream from the head mounting plate, a platen roller that defines the printing position A, and a back guide member disposed downstream from the platen roller. The head mounting plate and front guide plate have interlocking parts that interlock with each other widthwise to the paper transportation path. A paper detector that detects entry of the recording paper 45 is disposed to a gap E between the back guide member and platen roller. When the paper detector detects the recording paper 45, a rotation control unit stops the platen roller.
