Pressurized fluid cartridge e.g. ink cartridge attached in e.g. inkjet printer, has main portion whose rear surface is provided with one surface in insertion direction relative to front surface and other surface closer to front surface

摘要

#CMT# #/CMT# The cartridge (30) has a main portion with a pressure fluid chamber (36) that is established to store fluid under pressure. A rear surface of main portion is arranged at a distance from a front surface in an insertion direction. A pressurized fluid section is arranged on front surface in order to establish a connection between interior and exterior of pressure fluid chamber. The rear surface of main portion is provided with a specific surface in an insertion direction relative to front surface and other surface located closer to the front surface. #CMT# : #/CMT# An independent claim is included for recording apparatus. #CMT#USE : #/CMT# Pressurized fluid cartridge e.g. ink cartridge attached in cartridge attachment unit of recording apparatus (claimed) e.g. inkjet printer. #CMT#ADVANTAGE : #/CMT# Since the surface of main portion is provided with specific surface in insertion direction relative to front surface and other surface located closer to the front surface, the ink cartridge can be effectively inserted in cartridge attachment unit even when the user exerts the compressive force on specific surface in the insertion direction. Thus, the inclination of guide portions of ink cartridge relative to the guide rails in a direction intersecting with the insertion direction can be prevented. As the pressing force is exerted on the guide portions parallel to the insertion direction, the friction generated between the guide portions and guide rails can be suppressed. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of an internal structure of the printer. 10 : Printer 30 : Pressurized fluid cartridge 36 : Pressure fluid chamber 100 : Ink feed device 110 : Cartridge attachment unit.
