PROBLEM TO BE SOLVED: To realize an ink bottle installing device, in which the pulling-out work of an ink bottle can be easily done with a small pulling-out force. SOLUTION: In an ink pump 2, an ink suction port part 3, a ring housing groove 3a, in which an O-ring 4 is arranged, is provided. In an ink bottle 5, an ink supply port part 7 is provided. By inserting the ink supply port part 7 of the ink bottle 5 in the ink suction port part 3, the O-ring 4 is compression- deformed, resulting in sealing the gap between the ink suction port part 3 and the ink supply port part 7 in an ink bottle installing device under the condition that the width W1 in the inserting-in and pulling-out direction of a bottle of the ring housing groove 3a of the ink suction port part 3 is provided larger than the width W2 at the compression deformation of the O-ring 4.
