Title: Ink jet head unit and printer mounting it
Inventor: OTSUKI NOBORU
IPC: B41J2/045
Filed: 2002-08-21
Abstract: PROBLEM TO BE SOLVED: To provide a small and compact head unit in which incomplete printing, e.g. missing of dots, due to pressure variation incident to movement of the head unit can be prevented surely. SOLUTION: The head unit 4 of an ink jet printer comprises a head chip 12 fixed to the front face of a unit body 13 and four damper chambers 21(1)-21(4) formed on the rear surface while being sectioned in the direction parallel with the ink nozzle face 12a. Each damper chamber 21(1)-21(4) communicates with the ink nozzle of the head chip 12 through an ink supply opening 23(1)-23(4) made through the unit body 13. Since the ink supply openings 23(1)-23(4) are extremely short, pressure variation occurring at the relevant part as the head unit 4 moves is insignificant and thereby incomplete printing, e.g. missing of dots, is prevented.  Since the damper chambers are arranged along the moving direction A of the head unit and a head unit 4 having small dimensions in the direction orthogonal to the moving direction can be realized, a space required for movement of the head unit 4 can be reduced resulting in small and compact ink jet printer.
