Patent ID: 7543909

Claim:
A wiper device comprising: a first wiper that wipes a nozzle surface defined in a liquid ejection head; a second wiper that wipes a side surface of the liquid ejection head extending in a direction intersecting the nozzle surface, the second wiper being formed separately from a cap that seals the nozzle surface of the liquid ejection head; and a drive mechanism that drives the first and second wipers to move between respective standby positions and wiping positions, the drive mechanism operating to move the second wiper to the corresponding wiping position independently from the first wiper, wherein the drive mechanism includes one or more drive sources and a transmission mechanism that transmits drive force generated by the one or more drive sources to the first and second wipers, the transmission mechanism including a time-lag mechanism that delays movement of the first wiper with respect to movement of the second wiper when the first and second wipers are moved from the respective standby positions to the respective wiping positions by the drive force.
