Wiper device and fluid ejection device

摘要

A wiper device of a printer has four wiper units arranged in a line to wipe the nozzle faces of an inkjet head. Each wiper unit has a first intermittent gear and a second intermittent gear which sequentially mesh with first and second drive gears and sequentially transverse axis X a wiping operation and a cleaning operation. The wipers move vertically to the nozzle faces. A wiper cleaner lever-rocks between a closed position covering the wiper and an open position not touching the wiper, moves through a path not interfering with the wiper in an opening operation, and through a path wiping the wiper and removing ink and other accretions from the wiper in a closing operation.

主权项

1. A wiper device comprising:
a drive shaft that turns based on rotation of a motor; and a plurality of wiper units disposed in a line along the drive shaft to wipe based on rotation of the drive shaft in one direction,
each wiper unit having a wiper configured to perform a wiping operation moving between a retracted position where the wiper does not contact the nozzle face of a fluid ejection head, and a wiping position where the wiper can wipe the nozzle face of the fluid ejection head, anda wiper cleaner configured to perform a cleaning operation sliding against the wiper in a direction crosswise to the direction of wiper movement; wherein the wiper unit has a first rotary cam that rotates according to rotation of the drive shaft and drives the wiper cleaner in the cleaning operation, and wherein the first rotary cam moves the wiper cleaner in an opening operation from a closed position covering the top of the wiper at the retracted position to an open position not contacting the wiper in the wiping position, and a closing operation returning from the open position to the closed position.
