ABSTRACT:
A head cap is reciprocally movable between a capping position for covering nozzles of a print head and a retracted position separated from the nozzle surface. A pump is connected to the head cap. A pump gear is rotated by a drive source to drive the pump. A cylindrical cam is reciprocally rotatable between a first position and a second position to reciprocally move the head cap. A frictional clutch rotates the cylindrical cam together with the pump gear, but rotates only the pump gear when the cylindrical cam reaches each one of the first position and the second position.
