Patent ID: 8313157

Claim:
An inkjet recording device comprising: a liquid-droplet ejection head comprising a plurality of nozzles for ejecting droplets of a recording liquid; a flexible tube member connected to the liquid-droplet ejection head; a tube pump disposed on the flexible tube member to supply the recording liquid to and suction the recording liquid from the liquid-droplet ejection head through the flexible tube member; a rotational press member disposed in the tube pump, the rotational press member, while rotating in a first rotation direction, sequentially compressing the flexible tube member to supply the recording liquid to the liquid-droplet ejection head and, while rotating in a second rotation direction opposite to the first rotation direction, sequentially compresses the flexible tube to suction the recording liquid from the liquid-droplet ejection head; and a controller communicatively connected to the tube pump, the controller causing the rotational press member of the tube pump to rotate in the first rotation direction and the second rotation direction opposite to the first rotation direction, wherein at least one portion of the flexible tube member is compressed by the rotational press member while the tube pump is stopped, and the controller, in response to an instruction to rotate the rotational press member in one of the first rotation direction or the second rotation direction, first causes the rotational press member to rotate in reverse with respect to the instructed first rotation direction or the second rotation direction and then rotate in the instructed first rotation direction or the second rotation direction.
