PURPOSE:To perform mounting and dismounting operation easily and certainly, by a method wherein opposed faces at a rear part in an insertion direction are inclined in an approaching direction to each other as the rear end is being approached, and projections are established at the rear ends of the opposed faces. CONSTITUTION:In mounting, an upper face 9 and an under face 10 which are formed slantwise at a rear part of an ink cartridge 1 are grasped and inserted to a specific position to some extent. Thereafter, a rear end face 13 is pressed to be inserted until a front face 14 and mounting is completed. Under such state, a hollow ink supply needle passes through a front opening of the ink cartridge 1 to pierce an ink supply hole 8 of an ink bag 6, and inside ink 30 is interconnected to an ink supply tube via the ink supply needle. Then, in dismounting, the cartridge 1 is grasped by doing likely to hang fingers on projections 11, 12 formed at the rear ends of the upper face 9 and the under face 10, and is pulled out this side as it is to complete dismounting. Mounting and dismounting operation can be thus easily and certainly performed. |
