Description

  The present invention relates to a lid opening / closing structure for an electronic device such as a digital camera, and more particularly to a lid opening / closing structure for a battery, a memory card, or the like.

Some conventional lid opening / closing structures include a support plate that is rotatable with respect to a housing and a lid that is slidably attached to the support plate. (For example, see Patent Document 1)
Hereinafter, a battery lid opening and closing device of a conventional digital camera will be described with reference to FIG. A battery housing part is formed on one side of the casing constituting the digital camera, and the opening of the battery housing part is configured to be opened and closed by a battery lid.

  A shaft member is inserted into a hole formed in the housing, and the shaft member is fixed. The support plate is pivotally supported by the shaft member. The battery lid is engaged with the support plate so as to be slidable in the in-plane direction of the battery lid and in the direction perpendicular to the shaft member. The housing and the inner surface of the battery lid are provided with an engaging portion, the inner surface of the battery lid is provided with a battery contact piece, and a battery contact piece (not shown) is also provided at the end of the battery storage portion.

  However, in the above conventional example, the angle formed between the side surface of the battery lid and the outer surface of the battery lid is vertical, so when the digital camera is viewed from the direction of the battery lid, the inside of the digital camera can be seen from the gap between the battery lid and the housing. The appearance quality was impaired. Further, since the battery lid is fixed only by the engaging portion against the biasing force in the opening direction of the battery lid due to the spring force of the battery contacting piece, the engaging portion is insufficient or the spring force of the battery contacting piece When the battery strength is high, the battery cover has insufficient rigidity.

  In order to solve the above problems, a first aspect of the present invention is such that a lid is attached to the casing so as to be openable and closable, and in the fully closed position, the lid has three or more side surfaces substantially parallel to the casing. The angle between the outer surface of the lid body and the side surface of the lid body is both an acute angle and an obtuse angle.

  According to the present invention, since the angle formed between the side surface of the lid and the outer surface of the lid is an acute angle or an obtuse angle, when the housing is viewed from the direction of the outer surface of the lid, the interior of the housing is not visible and high appearance quality can be provided. .

  In addition, since the side surface of the lid body forms both an acute angle and an obtuse angle, it is possible to provide a lid opening / closing structure with little backlash with respect to the urging force in the opening direction and the closing direction of the lid body in the fully closed state of the lid body.

  Furthermore, even when an external force in the opening direction from the fully open position of the lid acts on the lid, the lid side surface and the outer surface of the housing are in contact with each other to withstand the external force, thereby providing a highly rigid lid opening / closing structure. I can do it.
