Abstract
The present invention provides a nozzle face wiping device and an image recording device that can switch whether to wipe out a nozzle face by a simple mechanism. According to one mode of the present invention, it is possible to brake the running of the wiping web by the braking device on the upstream side (supply shaft side) of the pressure member. In a case where the running direction of the wiping web wound around the pressure member and the relative movement direction of the nozzle face are the same, it is possible to prevent the wiping web from being forcefully drawn out from the supply shaft by braking the running of the wiping web by the braking device. By this means, it is possible to wipe out the nozzle face from two directions.
Claims10
A nozzle face wiping device that relatively moves along a nozzle face of an ejection head and wipes out the nozzle face, the nozzle face wiping device comprising:
- a rotatable supply shaft;
- a wiping web that is wound in a roll manner and attached to the supply shaft;
- a winding shaft;
- a wiping web running drive device which winds the wiping web around the winding shaft and running the wiping web;
- a pressure member that presses and contacts the wiping web to the nozzle face while being wound by the wiping web that runs between the supply shaft and the winding shaft;
- a braking device which brakes running of the wiping web on an upstream side of the pressure member with respect to a running direction of the wiping web;
- a rotation detection device which detects the rotation of the supply shaft;
- a wiping web running trouble detection device which detects a running trouble of the wiping web in accordance with a detection result of the rotation detection device, wherein when the rotation of the supply shaft is detected by the rotation detection device while drive of the winding shaft by the wiping web running drive device stops, the wiping web running trouble detection device determines that the running trouble of the wiping web exists;
- and
- a warning device which generates warning when the running trouble of the wiping web is detected by the wiping web running trouble detection device.
A nozzle face wiping device that cleans a nozzle face of an ejection head, the nozzle face wiping device comprising:
- a wiping web that is contacted to the nozzle face and wipes out the nozzle face;
- a wiping web running drive device which runs the wiping web along a longitudinal direction;
- a pressure member that presses and contacts the wiping web to the nozzle face;
- a biasing device which gives force to press the wiping web to the nozzle face through the pressure member;
- and
- a tension giving device which gives tension to the wiping web by making running speed on a downstream side of the wiping web with respect to the pressure member faster than running speed on an upstream side of the wiping web, and moving the pressure member in a direction against biasing force of the biasing device,
- wherein whether to wipe out the nozzle face is switched by giving the tension.
