  Therefore, an object of the present invention is to eliminate the above-mentioned problems, for example, even in a mode in which the lid is opened and closed by a sliding operation, the engagement member can be attached closer to the lid, and the usability is improved. It is to improve more.

  In order to achieve the above object, the present invention has an engagement member pivoted to a lid body that opens and closes a main body side opening, and the engagement member is engaged with a corresponding portion of the main body to move the lid body. In a lock mechanism that switches from a locking position that regulates to a releasing position that releases the locking and allows movement in the opening direction of the lid by a pressing operation against an urging force, the engaging member includes: A claw portion that is pivotally supported on the back surface side of the lid via a shaft portion and the like, is provided on the front side of the shaft portion, and is engaged with and disengaged from the locking portion of the main body, and a rear side of the shaft portion An engaging portion that is slid in the front-rear direction of the back surface of the lid and is operatively connected to the connecting portion. And a button portion disposed on the surface side of the lid body from a window provided in the lid body, When the pressing operation is performed via the recording button portion, the engaging member is resisted against the biasing force of the spring member, and is rotated in the release position direction via the operation connection between the connecting portion and the engaging portion. It is characterized by that.

  The above locking mechanism is suitable for a mode in which the lid is opened and closed by sliding with respect to the opening on the main body side, but can also be used in a mode in which the lid is rotated and opened. Compared to the conventional structure shown in FIG. 7, the contrivance point is that the button part side is separated from the engaging member and formed on the slider, so that the problem mentioned in the problem is solved and both the engaging member and the slider are covered. This means that it can be placed close to the back or inner surface of the body.

  Further, the lock mechanism of the present invention is slidably guided in a state in which the shaft portion protruding from the side surface of the slider is fitted in a guide hole provided on the back surface side of the lid (Claim 2). The lid opens and closes the opening of the main body by a sliding operation, has a recess, forms the window in a wall portion defining the recess, and opens the opening of the main body The direction in which the lid is pressed and the direction in which the button is pressed to switch the engagement member to the release position are set to be the same (Claim 3), and the connecting portion is formed on the projecting piece. It is preferable that the engaging portion is formed in a reverse recessed portion or a hole portion that can be operated and interlocked with the protruding piece.

The lock mechanism according to the present invention can have the following advantages.
In the first aspect of the invention, by separating the button portion side from the conventional engaging member and forming it on the slider, the first problem mentioned in the problem is solved, and both the engaging member and the slider are made of the lid. It is possible to arrange close to the back surface or the inner surface, thereby reducing the degree to which the actual volume in the main body becomes small due to the presence of the lock mechanism, and making it possible to use the inside of the main body more effectively.
In the invention according to claim 2, the slider is slid satisfactorily by the guide action of the shaft portion and the guide hole with respect to the lid, and as a result, a stable switching operation is maintained as the lock mechanism.
In the invention of claim 3, for example, there is a direction in which the button part is pressed to release the claw part and a direction in which the lid body is pressed in the opening direction to solve the second problem mentioned in the problem. From the same thing, it has excellent operability and can improve usability.
