Abstract
In an ink jet printer, a carriage carrying print heads engages with a print head cap support member when the carriage reaches a position where the print heads are positioned opposite to a print head cap supported on the print head cap support member during its movement toward a capping position where the print heads are capped with the print head cap, and moves together with the print head cap support member. As the carriage moves further toward the capping position, an operating member is operated by a cam to operate the print head cap so as to move toward the print heads for capping operation. Thus, the movement of the carriage and the capping operation of the print head cap are perfectly and accurately synchronized. A purging unit is driven through a gearing including a pump driving cam gear by a line feed motor.
