IPC: B41J2/14
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To reduce the consumption of ink by a structure wherein a ball for giving impulses to a membrane is housed within a cavity and a vibrating means for vibrating the ball is formed below a barrier. SOLUTION: First of all, when a power supply is applied, a magnetic field is generated in a magnetic vibrator 50, resulting in violently vibrating a ball 40 housed in the cavity 31 of a barrier 30. Further, the ball 40 collides against a membrane 60 locating above during its vibration, resulting in oscillating the soft material membrane 60 through the stroke of the ball 40 so as to strike an ink chamber 20 in order to inject the ink in the ink chamber 20 through the nozzle orifice 11 of a nozzle plate 10. Thus, since the ink is injected through the orifice 11 due to the transmission of the vibration of the ball 40 in the cavity 31 to the ink chamber 20, a large number of nozzle per head can be provided and consequently the consumption of the ink is reduced.
