Abstract:
1. A liquid discharge apparatus comprising: a plurality of nozzles that discharge liquid; a liquid discharge head that includes nozzle arrays where the respective nozzles are arranged in one direction; a liquid adsorbent that adsorbs liquid attached to a portion of the liquid discharge head where the nozzle arrays are formed; a moving means for relatively moving the liquid adsorbent in an arrangement direction of the nozzles; support rollers that support the liquid adsorbent so as to allow the liquid adsorbent to rotate; a rotating shaft that corresponds to the axis of rotation of the support rollers and is rotated in a normal or reverse direction by using the relative movement of the liquid adsorbent, which is caused by the moving means, as a source of power; a reverse rotation preventing means for transmitting the normal rotation of the rotating shaft to the support roller and not transmitting the reverse rotation of the rotating shaft to the support roller; a slide part that is moved in an arrangement direction of the nozzles by the moving means; a swing part that is mounted on the slide part, holds the rotating shaft, and is lifted or lowered with respect to the slide part; and a guide portion that allows the swing part to be lifted or lowered as the slide part is moved, and guides the rotating shaft so that the rotating shaft is rotated in a normal or reverse direction.
