<P>PROBLEM TO BE SOLVED: To obtain a frame mechanism for an image forming apparatus, for attaching a marking part to a main body frame, with high precision. <P>SOLUTION: When a hexagonal head screw 42 is screwed into a through hole 84, a first attaching surface 82A is moved within a same surface of a through hole 84 (arrow A), and when a hexagonal head screw 41 is screwed into a through hole 83, a second attaching surface 82B is moved within a same surface of the through hole 83 (arrow B). That is, by making the first attaching surface 82A and the second attaching surface 82B orthogonal to each other, movement in the direction of an arrow C is made in a second attaching surface 82B, and movement in the direction of an arrow D is made in the first attaching surface 82A. Thus, movement of a joint bracket 82 in directions XYZ is made and even when misalignment occurs in the directions XYZ between a marking frame 14 and the main body frame 12, the misalignment is absorbed, and the marking frame 14 assembled with high precision is retained in a state of high precision. <P>COPYRIGHT: (C)2008,JPO&INPIT |
