Abstract

When the lid is rotated in the closing direction toward the first predetermined state from a second predetermined state where the lid is in an open state and the outer lid at a locked position, the projection of the outer lid and a wall portion of the case are brought into contact with each other in the gap, an inclined surface is formed on at least one of a portion, which is brought into contact with the wall portion of the case, of the projection of the outer lid and a portion, which is brought into contact with the projection of the outer lid, of the wall portion of the case, wherein the inclined surface is formed in an inclined manner such that as the inclined surface is farther from the axis of rotation, the inclined surface becomes farther from the predetermined surface.

First claim

What is claimed is:

1. An electronic device comprising:
a case having an opening on a predetermined surface; and
a lid which is capable of taking an open state where the opening is exposed and a closed state where the opening is not exposed,
the lid includes an inner lid and an outer lid,
the inner lid includes:
an inner lid body portion disposed approximately parallel to the predetermined surface when the lid is in a closed state; and
a hinge portion which connects the inner lid body portion to the case such that the inner lid body portion is rotatable about an axis of rotation parallel to the predetermined surface,
the outer lid includes:
an outer lid body portion held by the inner lid body portion in a slidably movable manner in the direction orthogonal to the axis of rotation;
a lid-side engaging portion formed on an end portion of the outer lid body portion away from the axis of rotation; and
a projection which is formed on an end portion of the outer lid body portion closer to the axis of rotation, and projects toward the axis of rotation,
the case has a case-side engaging portion which is engageable with a lid-side engaging portion in a closed state on the predetermined surface thereof,
the outer lid is slidably movable in the direction orthogonal to the axis of rotation between a locked position where the lid-side engaging portion and the case-side engaging portion are brought into contact with each other at the time of rotation and an unlocked position where a contact between the lid-side engaging portion and the case-side engaging portion at the time of rotation is alleviated,
the case has a wall portion formed at a position facing a lower end side of the predetermined surface in a state where a gap is formed between the wall portion and the predetermined surface, the wall portion is disposed so as to overlap the predetermined surface when viewed from a direction perpendicular to the predetermined surface,
when the lid is in a first predetermined state where the lid is in a closed state and the outer lid is at the locked position, the projection of the outer lid is inserted into the gap,
when the lid is rotated in the closing direction toward the first predetermined state from a second predetermined state where the lid is in an open state and the outer lid at a locked position, the projection of the outer lid and a wall portion of the case are brought into contact with each other in the gap,
an inclined surface is formed on at least one of a portion, which is brought into contact with the wall portion of the case, of the projection of the outer lid and a portion, which is brought into contact with the projection of the outer lid, of the wall portion of the case, wherein the inclined surface is formed in an inclined manner such that as the inclined surface is farther from the axis of rotation, the inclined surface becomes farther from the predetermined surface.

2. The electronic device according to claim 1 , wherein an inclined surface is formed on the first lid-side engaging portion and the first case-side engaging portion respectively, the inclined surface being formed such that as the inclined surface is farther from the axis of rotation, the inclined surface becomes closer to the predetermined surface.

3. The electronic device according to claim 1 , wherein outer lid-side projections are formed on an outer lid body portion of the outer lid, and inner lid-side projections are formed on an inner lid body portion of the inner lid, the outer lid-side projections and the inner lid-side projections hold a state where the outer lid is at an unlocked position, further, the outer lid-side projections and the inner lid-side projections are engageable with each other.
