PROBLEM TO BE SOLVED: To suppress meandering and deviation of a belt.SOLUTION: In a printer 1, the distance D1 between a top face of a rotating body 61 and an outer face of a belt 43 is shorter than the length D2 in which a guide rib 60 and a guide recess 52A overlap with each other in the radial direction of a support roller 42, in the vertical direction in the figure. Thus, even when the guide rib 60 floats from the guide recess 52A, the outer face of the belt 43 is brought into contact with the rotating body 61. The rotating body 61 is provided on an under frame 46 provided integrally with side frames 44 that receives the shaft of the support roller 42. |
