Abstract
A protrusion 31 formed at an end edge of a board that is not screw-fixed is inserted into a rectangular opening engaging section 25 formed on a chassis 2, sides of the board are mounted on a screw-fixing section (also serving as a board receiver) 21, and a first and a second board receiving sections 22, 26 that are formed on the chassis 2 by a cutting and raising manner, respectively, the board 3 is gripped by board gripping sections 23a, 23b, and one side of the board 3 is screw-fixed to the screw-fixing section (also serving as the board receiver) 21.
Claims6
A board fixing structure comprising:
- a box-shaped and hollow chassis, and a board
- wherein the chassis includes:
- a first board receiving section that is formed inwardly from a portion of each of two side plates of the chassis;
- a board gripping section that is formed inwardly from another portion of each of the two side plates thereof;
- a rectangular opening engaging section that extends at a substantially right angle from an edge of the upper end of a back side plate of the chassis;
- and
- a second board receiving section that is formed from both sides of the rectangular opening engaging section toward the interior of the chassis, and
- wherein the board includes:
- a protrusion formed at an edge thereof to engage with the rectangular opening engaging section.
A board fixing structure comprising a box-shaped and hollow chassis, and a board,
- wherein the chassis includes:
- a first board receiving section is formed by cutting and raising inwardly a portion of each of two side plates of the chassis, the two side plates opposing each other across a screw fixing-section also serving as a board receiver that is provided in the interior of the chassis;
- a board gripping section that is formed by cutting and raising inwardly another portion of each of the two side plates thereof;
- a rectangular opening engaging section that extends at a substantially right angle from an edge of the upper end of a back side plate of the chassis;
- and
- a second board receiving section at is formed by horizontally extending from both sides of the rectangular opening engaging section toward the interior of the chassis, and formed at the substantially same height position as those of the screw-fixing section also serving as the board receiver and the first board receiving section, and
- wherein the board includes:
- a protrusion formed at an edge thereof that is not screw-fixed to engage with the rectangular opening engaging section;
- and
- a screw passing hole for threadedly engaging with the screw-fixing section also serving as the board receiver.
