Patent ID: 8794739

Claim:
A liquid droplet jetting apparatus configured to jet liquid droplets of a liquid, the apparatus comprising: a liquid droplet jetting head having a nozzle from which the liquid droplets are jetted; a cap member having a suction port and an air intake port, and to be attached to the liquid droplet jetting head to cover the nozzle; a switching mechanism connected to the suction port and the air intake port of the cap member and configured to switch the air intake port between a state in which the air intake port communicates with the atmosphere and a state in which the air intake port is disconnected from the atmosphere, the switching mechanism including: a case member having: a first opening which is open to the atmosphere; a suction port connection portion which is connected to the suction port of the cap member; and an air intake port connection portion which is connected to the air intake port of the cap member; and a switching member contained in the case member to switch a position of the switching member with respect to the case member; and a suction mechanism connected to the switching mechanism; wherein, in a state that the cap member is attached to the liquid droplet jetting head, the switching member is configured to be switchable between a first position and a second position; wherein the first position is a position: at which a first communication passage for connecting the suction port connection portion and the suction mechanism is formed between the switching member and the case member; and at which the first opening and the air intake port connection portion are disconnected; and wherein the second position is a position: at which the first communication passage is formed between the switching member and the case member; and at which a second communication passage for connecting the first opening and the air intake port connection portion is formed between the switching member and the case member.
