PROBLEM TO BE SOLVED: To reduce running cost to a large extent and to easily take out an ink housing member because only the ink housing member can be taken out. SOLUTION: A housing case 12 contains halves 14a, 14b which are attached to a bottom plate 18 so as to be shakable around hinge parts 16a, 16b. Engaging parts 20a, 20b mutually engaged in such a state that the housing case 12 is closed are provided to the upper surfaces of the halves 14a, 14b. An ink housing member 30 filled with ink 28 is elastically housed in the housing case 12. Therefore, by mutually separating the engaging pieces 20a, 20b, the housing case 12 is elastically urged by the ink housing member 30 to become an open state. |
