<p><P>PROBLEM TO BE SOLVED: To correctly insert a protrusion to a joint with the end of the joint turned straight to the protrusion. <P>SOLUTION: In an exhaust unit 30 of an inkjet printer, an upstream side protrusion 29 that communicates to an exhaust stream channel is formed in the lower surface of a projection member 25c that is provided in a sub-tank unit, and a downstream side protrusion 36 that communicates to an opening and closing channel is formed on the top face of a cover 33 that is arranged in vertical direction leaving space with the projection member 25c. The tips of the upstream side protrusion 29 and the downstream side protrusion 36 are opposed mutually. A guide plate 43 is installed upright in parallel to the upstream side protrusion 29 from the projection member 25c. Then, the guide plate 43 has a guide surface 43a opposed to a part of the peripheral surface of the upstream side protrusion 29. As for the cylindrical part of a joint rubber, the upstream side protrusion 29 is inserted in the upper end, and the downstream side protrusion 36 is inserted in the lower end. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
