Case structure
A case structure includes: a case having an opening at one end side; a cover configured to close the opening; and a pressing and holding portion configured to press and hold a board against the case when the cover applies a force to the board in a state where the board is accommodated in the case and the cover is closed.
1. A case structure comprising:
a case having an opening at one end side;
a cover configured to close the opening; and
a pressing and holding portion configured to press and hold a board against the case when the cover applies a force to the board in a state where the board is accommodated in the case and the cover is closed, wherein
the case includes a wide member having two guide surfaces that face respectively an upper surface side and a lower surface side of the board in order to guide the board inserted from the opening along a guide path, and
the pressing and holding portion includes
a pressing member provided on the cover that abuts onto the board and applies a pressing force pressing the board to one guide surface among the two guide surfaces, the pressing member including a pressing portion provided on an upper surface of the pressing member and protruding upward, and
a regulating member provided on the cover that regulates displacement of the guide member due to the pressing force when the pressing portion of the pressing member contacts the board by abutting onto a surface of the guide member opposite to the guide surface against which the board is pressed by the pressing force from the pressing member, the regulating member being disposed above the pressing member.
2. The case structure according to claim 1 , wherein
a projection that applies a pressing force in the same direction as a direction in which the pressing force by the pressing member is applied to the board by abutting onto a front end portion of the board in an insertion direction into the case is formed on the other guide surface among the two guide surfaces.
3. The case structure according to claim 1 , wherein
a portion close to the opening in the guide member having the other guide surface among the two guide surfaces is removed and a length in a guide direction of the guide member having the other guide surface among the two guide surfaces is made shorter than a length in the guide direction of the guide member having the one guide surface such that an open space is formed at an outer end side of the guide member having the other guide surface, and
the pressing member is accommodated in the open space.
4. The case structure according to claim 2 , wherein
a portion close to the opening in the guide member having the other guide surface among the two guide surfaces is removed and a length in a guide direction of the guide member having the other guide surface among the two guide surfaces is made shorter than a length in the guide direction of the guide member having the one guide surface such that an open space is formed at an outer end side of the guide member having the other guide surface, and
the pressing member is accommodated in the open space.
