PROBLEM TO BE SOLVED: To provide a device such as an image recorder having a large number of rollers and nip pressures different from each other and capable of easily identifying whether a nip pressure adjusting spring can be applied to any feed roller or not by coloring, with a proper color, a part or all of the nip pressure adjusting spring applied with the nip pressures. SOLUTION: When both end parts 4b of an adjusting spring 4 is locked to the locking part 2c of a guide bracket 2 for supporting the upper roller 35a of a feed roller 35 formed of the upper roller 35a and a lower roller 35b and the center part is joined to the upper roller 35a, the upper roller 35a is pressed against the lower roller 35b by the recovering force of the adjusting spring 4 to produce the nip pressure. A colored part 4a is provided on a part of the adjusting spring 4 and a proper color is applied thereto. Thus, the adjusting spring 4 having the locking part 2c colored with the same color and colored with the same color as that on the locking part 2c is set up.
