<p>PROBLEM TO BE SOLVED: To provide an image formation device making it possible to upgrade a sound insulation effect despite a simple arrangement without an increase in a man-day for assembling or a rise in a cost due to addition of a component.SOLUTION: In an image formation device having a paper feed cassette 2 loaded in a device body 1 through an opening 1a, which opens onto the device body 1, so that the paper feed cassette 2 can be drawn out, a gapδto be created between the opening 1a of the device body 1 and the paper feed cassette 2 is blocked by meshing part of the perimeter of the opening 1a of the device body 1 with part of the paper feed cassette 2 in a concavo-convex manner. For example, a concave part 11a is formed in a width direction below a multi-frame 11 that faces the upper margin of the opening 1a of the device body 1, and a convex part 12a is formed in the width direction above one end in a longitudinal direction of the paper feed cassette 2. The concave part 11a and convex part 12a are meshed with each other by loading the paper feed cassette 2 in the device body 1.</p> |
