INKJET DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an inkjet device which can prevent the rupture of a spring due to a friction between the spring and a rod from occurring and ensures the easy replacement of the spring. SOLUTION: The inkjet device comprises a cylinder 1a in which a piston 3 is internally built in a freely sliding manner; an ink reservoir 1 equipped with an opening 1b for discharging an ink; a discharge nozzle 2 fitted to the opening 1b; an actuator 14 which consists of a piston support plate 5 where one end of a bar-like member is connected with the piston 3 through a support and a solenoid 4 for driving the piston support plate 5 and drives the piston 3 to slide inside the cylinder 1a; and a spring urging means 15 with a spring 10 for urging a spring loading to the piston 3 in the discharge direction. The spring urging means 15 is arranged outside the ink reservoir 1. COPYRIGHT: (C)2005,JPO&NCIPI
