<p>The invention provides a damper apparatus including a housing having a valve chamber and reciprocally moving integrally with a carriage, an inlet port communicating an ink flow channel on the upstream side and the valve chamber, an outlet port communicating the ink flow channel on the downstream side and the valve chamber, and a spherical valve body stored so as to be movable in the valve chamber, wherein the valve body moves relatively to a position for closing the inlet port or the outlet port upon reception of the inertial force in association with the acceleration and deceleration to close the ink flow channel when the carriage is accelerated or decelerated, and the valve body moves relatively to a position for opening the inlet port and the outlet port under its own weight to open the ink flow channel when the carriage is not accelerated and decelerated.</p> |
