Patent ID: 8602521

Claim:
A cap device comprising: a transmitting mechanism that transmits the rotation of a driving side member to an elongate driven-side member, the transmitting mechanism including an engaging claw selectively engaging with the driving side member to selectively drive the driven-side member, the transmitting mechanism including a rotation suppressing portion selectively engaging with an engaging member including the engaging claw, the rotation suppressing portion being configured to selectively suppress rotational motion of the engaging member away from the driving side member; and a cap that moves between a contact position where the cap comes into contact with a liquid ejecting head which ejects ink using the rotation of the driven-side member and a separating position where the cap is separated from the liquid ejecting head, wherein the transmitting mechanism transmits the rotation of the driving-side member only in one direction to the driven-side member in a state where the cap reaches the contact position, and wherein the transmitting mechanism transmits the rotations of the driving-side member in both one and the other directions to the driven-side member during at least one of a period in which the cap moves from the contact position to the separating position and/or a period in which the cap moves from the separating position to the contact position.
