Abstract: A wiping device includes a wiper unit, a carriage, and a fixing member. The wiper unit includes a wiper that wipes a liquid discharge surface of a liquid discharge head from which liquid is to be discharged. The carriage moves along the liquid discharge surface in a first direction and a second direction, both of which are opposite to each other. The fixing member fixes the wiper unit to the carriage. When the carriage is disposed on a side in the first direction with respect to a middle point in a moving range of the carriage, the fixing member is removable in the first direction.

Abstract: A printer includes a line head and a wiper unit. The line head is provided to be movable between a recording position and a retreat position and performs recording on a medium by ejecting ink from an ejection surface at the recording position. The wiper unit is provided to be movable, in the Y direction, between a maintenance position at which a maintenance operation is able to be performed and a non-maintenance position away from the maintenance position. A permitting section is formed in the wiper unit. The permitting section permits a portion of the line head to move in a direction intersecting the Y direction in a state in which the wiper unit is at the non-maintenance position.

Abstract: A pump apparatus includes: a stationary shaft; a rotation-regulating member having a coil main body wound around the stationary shaft, the rotation-regulating member being permitted to rotate in a direction of loosening the coil main body and the rotation-regulating member being restrained from rotating in a direction of tightening the coil main body; a driven rotatable member that may rotate around the stationary shaft when a driving force of a driving source is transmitted; and a suction pump that has a rotary member driven together with rotation of the driven rotatable member and that performs a suction operation when the rotary member rotates. The suction pump is configured such that the rotation-regulating member rotates in the tightening direction of the coil main body when the driven rotatable member rotates in a direction opposite to a direction in which the driven rotatable member performs the suction operation.

Abstract: A wiping module includes a wiping portion and a cleaning portion. The wiping portion includes a wiping member wiping a liquid discharge head that discharges a liquid from a nozzle provided on a nozzle surface, a storage support portion supporting the wiping member and configured to store the liquid by the wiping, and a movement support portion mounting the storage support portion and configured to reciprocate along a wiping direction, which is a direction in which the wiping is performed. The cleaning portion cleans the wiping member. The cleaning portion includes a cleaning member and a guide portion guiding the cleaning member. The cleaning member is configured to follow a movement of the wiping portion in the wiping direction and to scrape off the liquid adhering to the wiping member while being guided by the guide portion.
