Abstract:
1. A liquid jetting apparatus which jets a liquid, comprising: a liquid jetting head which has a liquid jetting surface including a nozzle placement region at which a plurality of nozzles through which the liquid is jetted are open; a cap member which covers the nozzles of the liquid jetting head and which includes a bottom wall and a loop-shaped lip portion which is provided upright on an outer peripheral portion of the bottom wall to come into close contact with the liquid jetting surface, the bottom wall having a first region which covers the nozzle placement region and a second region which extends out from the first region and which does not face the nozzle placement region; a cap driving mechanism which moves the cap member to make contact with or separate from the liquid jetting surface of the liquid jetting head; a recovery mechanism which is connected to the cap member and which performs a recovery operation to discharge the liquid from the nozzles in a state in which the cap member makes contact with the liquid jetting surface; and a plate-shaped cap chip which is accommodated in the cap member to suppress the cap member from deforming during the recovery operation, wherein the cap driving mechanism tilts the cap member so as to cause the first region to separate from the liquid jetting surface earlier than the second region under a condition that the cap member separates from the liquid jetting surface, and wherein on a portion of the cap chip, corresponding to the second region, a thick portion, which has a thickness greater than a portion corresponding to the first region, is provided.
