PROBLEM TO BE SOLVED: To provide an information processing device and a settlement terminal device in which rapid falling and closing of a lid part can be prevented and the lid part can be easily closed when replacing a printing roll without increasing the number of components.SOLUTION: At one of a body 20 and a lid part 30, a pair of arc surfaces 43, 44 is provided that curves around an axis CL of a rotary shaft 25 and faces each other. In addition, at the other of the body 20 and the lid part 30, a slide contact member 48 is provided that is in slide contact with each of the arc surfaces 43, 44 when engagement between a shaft 65 and a movable claw 53 is released. Therefore, the slide contact member 48 is in slide contact with the arc surface 43 when the engagement between the shaft 65 and the movable claw 53 of a lock part 50 is released to open the lid part 30, so that it can be prevented that the lid part 30 rapidly falls to close due to the self-weight during opening without increasing the number of components. In addition, the lid part 30 in an open state can be easily closed by only resisting frictional resistance due to the slide contact member 48. |
