Abstract

A cabinet structure includes multiple cover members configured to spatially partition an inside from an outside of a cabinet, and a clearance communicating between the inside and the outside of the cabinet is left between two cover members, the two cover members being adjacent to each other, of the cover members, and a passage defined by the clearance and leading from the inside to the outside of the cabinet through the clearance has a shape with multiple bends.

First claim

What is claimed is:

1 . A cabinet structure including multiple cover members configured to spatially partition an inside from an outside of a cabinet, the cabinet structure comprising:
a clearance communicating between the inside and the outside of the cabinet is left between a first cover member and a second cover member, the first and second cover members being adjacent to each other; a first protrusion protrudes into the inside of the cabinet from the first cover member; and a second protrusion protrudes into the inside of the cabinet from the second cover member, wherein the clearance is formed so that a tip of the first protrusion in a protruding direction is surrounded by the second protrusion, and wherein a length L 2 is larger than a length L 1 , where a length between the first cover member and the tip of the first protrusion is designated by L 2 , and a length of an area, at which the first protrusion and the second protrusion overlap with each other, in the protruding direction of the first protrusion is designated by L 1 .

2 . The cabinet structure according to claim 1 , wherein the length L 1 is equal to or more than 3 mm.

3 . The cabinet structure according to claim 1 , wherein a path, formed of the clearance, from the inside toward the outside of the cabinet includes a plurality of bending portions.

4 . The cabinet structure according to claim 3 , wherein number of the bending portions is equal to or more than three.

5 . An electronic equipment comprising:
a sound source emitting sound in operation; and a cabinet configured to cover the sound source, wherein the cabinet structure according to claim 1 is used as the cabinet.

6 . An image forming apparatus including a driving unit, comprising:
the electric equipment according to claim 5 , wherein the sound source is the driving unit.

7 . The image forming apparatus according to claim 6 , wherein at least one of the two cover members that leave the clearance therebetween is a hinged cover member being operable to open and close.

8 . The image forming apparatus according to claim 6 , wherein at least one of the two cover members that leave the clearance therebetween is detachable from a body of the cabinet structure.
