Patent number: 7401879Abstract: A liquid ejection head is operable to eject a liquid droplet toward a target position. A transporter transports a first target medium toward the target position in a first direction. A guide member has a guide face along which a tray member on which a second target medium is mounted is fed toward the target position in a second direction which is opposite to the first direction.
