Abstract:
1. A liquid jetting apparatus which jets a liquid to a recording medium, comprising: a liquid jetting head which has a liquid jetting surface, the liquid jetting surface being formed with a nozzle from which the liquid is jetted to the recording medium; a wiper which makes contact with the liquid jetting surface to bend and wipes away the liquid adhered to the liquid jetting surface; a movement mechanism which moves the wiper relative to the liquid jetting surface in a wipe direction along the liquid jetting surface; a movement controller which stops the wiper, which has wiped away the liquid adhered to the liquid jetting surface by being moved relative to the liquid jetting surface in the wipe direction by the movement mechanism while making contact with the liquid jetting surface, at a stop position facing an area on a downstream side of the wipe direction with respect to the nozzle of the liquid jetting surface; and a separating mechanism which separates the wiper having been stopped by the movement controller from the liquid jetting surface in a separating direction intersecting the liquid jetting surface, wherein: at least an end portion, of the wiper, which makes contact with the liquid jetting surface is elastic; a groove in which the end portion of the wiper positioned at the stop position is accommodated is formed in the area on the downstream side of the wipe direction with respect to the nozzle; the groove has a contact surface with which the end portion of the wiper positioned at the stop position makes contact; and the groove is configured such that a bending amount of the wiper when the end portion of the wiper is in contact with the contact surface is smaller than a bending amount of the wiper when the end portion of the wiper is in contact with the liquid jetting surface in another area different from the area in which the groove is formed, and that the wiper is not completely recovered to an original state when the end portion of the wiper is in contact with the contact surface.
