Title: Ink jet recorder
Inventor: KADOWAKI AKIHIKO
IPC: B41J2/165
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To surely wipe ink adhered to a nozzle face and a face of an auxiliary plate at the circumference of the nozzle face without raising a cost and to prevent scattering of ink at the wiping. SOLUTION: A width of a wiper 4a is made greater than a width of an auxiliary plate 12 in the direction of nozzle arrangement by 1 mm or more. As the width of the wiper 4a is made wider, portions which are not contacted with the auxiliary plate 12 are left in the wiper 4a at both ends, respectively. The portions allow ink collected by the wiping to flow downward and allow the wiper 4a to move slowly when recovering from the curved condition after completion of the wiping, thereby reducing the scattered ink. This is effective when using the wiper 4a having the width wider than the auxiliary plate 12 by 1 mm, but not effective when the width is wider by 6 mm or more.
