<P>PROBLEM TO BE SOLVED: To surely avoid such a situation that a jetting head is clogged because air bubbles are formed in a channel or the like on the way when supplying liquid to the jetting head from a liquid tank. <P>SOLUTION: The liquid tank includes a liquid storing chamber for storing liquid, and an outlet chamber communicating with the liquid storing chamber and connected to the jetting head. The liquid tank further includes a pressure reducing means at a portion where the liquid storing chamber and the outlet chamber communicate with each other. Thus, the liquid necessarily passes through the pressure reducing means, and then it is supplied to the jetting head. Further, the air bubbles formed by the pressure reducing means are trapped by the outlet chamber on a downstream side. As a result, such a situation that the jetting head is clogged because the liquid is bubbled can be surely avoided. <P>COPYRIGHT: (C)2013,JPO&INPIT |
