Electronic apparatus

1 . An electronic apparatus comprising:

a chassis including:

an upper cover that defines a left-right direction and a front-rear direction of the chassis;

a first side wall and a second side wall that protrude, in a thickness direction of the chassis, from opposite peripheral edges of the upper cover in the left-right direction;

for each of the first side wall and the second side wall, two bosses that protrude:

in the thickness direction of the chassis, from an inner face of the upper cover, and also

in the left-right direction of chassis, from an inner face of the corresponding side wall; and

for each of the bosses, a corresponding positioning pin that protrudes in the thickness direction of the chassis;

a keyboard fastened to the upper cover by first screws;

at opposite ends of the keyboard in the left-right direction, a first bracket fastened to the first side wall and a second bracket fastened to the second side wall; and

an electronic board that is supported by the first bracket and the second bracket,

wherein each of the first bracket and the second bracket includes:

bracket holes that accommodate second screws that fasten to the two bosses of the corresponding side wall;

positioning holes that accommodate the corresponding positioning pins on the two bosses of the corresponding side wall; and

studs that accommodate third screws that fasten the electronic board to the corresponding bracket;

wherein the first bracket and the second bracket are fastened to the first side wall and the second side wall without fastening to the keyboard,

wherein the electronic board is fastened to the first side wall and the second side wall, via the first bracket and the second bracket respectively, without fastening to the keyboard and without fastening to the upper cover.

2 . The electronic apparatus according to claim 1 , wherein

the third screws corresponding to the studs have a larger nominal diameter than the second screws corresponding to the two bosses, and

the first bracket and the second bracket each include more bracket holes than studs.

3 . The electronic apparatus according to claim 1 , wherein

the first bracket includes a connecting piece that is offset from an outer edge of the first bracket in the left-right direction to form an open space between two of the bracket holes and two of the studs of the first bracket, and

the second bracket includes a connection piece that is extends along an outer edge of the second bracket in the front-rear direction.

4 . The electronic apparatus according to claim 3 , wherein

each of the first bracket and the second bracket include portions that protrude from the corresponding outer edge, in the left-right direction, toward the corresponding side wall of the chassis, and

the positioning holes are disposed at the portions that protrude from the outer edges of the first bracket and the second bracket.

5 . The electronic apparatus according to claim 1 , wherein

the first bracket and the second bracket each include additional bracket holes that are offset from the corresponding side wall of the chassis in the left-right direction and that accommodate additional second screws that fasten to additional bosses protruding, in the thickness direction of the chassis, from the inner face of the upper cover.

6 . The electronic apparatus according to claim 5 , wherein

each of the first bracket and the second bracket are adjacent to and separate from a hinge at opposite ends of the keyboard in the left-right direction.

7 . The electronic apparatus according to claim 6 , wherein

one of the additional bracket holes in each of the first bracket and the second bracket is adjacent to the hinge.

8 . The electronic apparatus according to claim 1 , wherein

the studs of each of the first bracket and the second bracket are aligned in the front-rear direction.

9 . The electronic apparatus according to claim 1 , wherein

each of the first bracket and the second bracket further include a spacer.

10 . The electronic apparatus according to claim 9 , wherein

for each of the first bracket and the second bracket, the spacer is disposed farther from the corresponding side wall than the studs in the left-right direction.

11 . The electronic apparatus according to claim 9 , wherein

for each of the first bracket and the second bracket, the spacer is disposed farther from the hinge than the studs in the front-rear direction.
