  • Ink-jet recording apparatus and method for driving the same
    Patent number: 7384118
    Abstract: An ink-jet recording apparatus has a pick-up roller for supplying to a conveyor mechanism an uppermost one of record media on a supporter, an elevator for moving up and down the supporter, a pump for forcibly ejecting ink within an ink-jet head, a drive shaft that is rotated both in positive and negative directions by a drive source, and a driving force transmitter. The driving force transmitter is capable of switching its mode between a mode for transmitting rotating force of the drive shaft in the positive direction to the pump so as to drive the pump and a mode for transmitting rotating force of the drive shaft in the negative direction to the pick-up roller so as to drive the pick-up roller. After the elevator is controlled to bring the uppermost one of the record media on the supporter away from the pick-up roller, the drive source is controlled to rotate the drive shaft in the positive direction.
