PROBLEM TO BE SOLVED: To improve detection accuracy for an ink end by arranging an action point where an ink end detection lever is activated, at a middle point of a fulcrum and a free end when the quantity of ink is not larger than a predetermined value, and arranging an ink end detector at the side of the free end of the ink end detection lever. SOLUTION: A rectangular notched part 63a is formed at part of a frame 63. An ink end detection lever 75 is set to the notched part 63a in a manner to be rotatable. Specifically, the ink end detection lever 75 is shaped like a flat plate having an axial part 75a formed at one end. The axial part 75a is axially supported between a pair of rise parts 62b integrally formed with a lower side plate 62 and a pair of erection parts 63b formed at the frame 63 and is made rotatable. An ink end detector 76 is disposed at an outside part of the lower side plate 62. A lever 76a set at the ink end detector 76 is operated by a projecting element 75b formed at the side of a free end of the ink end detection lever 75. |
