Patent number: 6742882Abstract: An inner surface of a ceiling wall is provided at an angle of approximately 5 degrees to 10 degrees, with respect to a horizontal surface. An outlet to a second ink channel is disposed at a higher position of the ceiling wall than a first ink channel. An inlet connected to the first ink channel is provided such that an end of the inlet terminates near a bottom of a buffer tank. When a circulation purge operation is performed by circulating ink from a sub-tank to the buffer tank, through the first ink channel, and from the buffer tank to the sub-tank, through the second ink channel, air bubbles in the buffer tank move along the angled or inclined inner surface of the ceiling wall, to the outlet provided at a higher position. The air bubbles are smoothly discharged through the outlet. The air bubbles collected to the sub-tank are released into the atmosphere through an air releasing portion.Type: GrantFiled: June 25, 2002Date of Patent: June 1, 2004Assignee: Brother Kogyo Kabushiki KaishaInventor: Hirotake Nakamura
