In a portable electronic device having a conventional lid, when removing the lid from the housing, a method is adopted in which the lid at the end of the slide is pressed from the surface and elastically deformed to release the locked state. It is necessary that the lid is easily elastically deformed when pressed. However, the ease of elastic deformation of the lid causes a problem that a click feeling is not sufficiently obtained when the lid is slid to the slide end position to attach the lid to the housing and the lid is locked to the housing.
Also, the ease of elastic deformation of the lid causes a problem that the lid can be easily removed when it is subjected to an impact force such as when it is dropped with the lid attached to the housing.

  Accordingly, an object of the present invention is to provide a portable electronic device in which the lid can be easily attached and detached, the click feeling when the lid is closed is sufficiently obtained, and the lid does not easily come off when subjected to an impact force. Is to provide equipment.

In the portable electronic device according to the present invention, an article storage chamber is formed at the back of the opening formed in the housing, and a lid that opens and closes the opening is detachably attached to the housing. The housing is provided with a slide guide portion that guides the slide of the lid along the opening, and the first end of the lid is locked to the housing at the slide end position where the opening is closed. A portion at a slide end position with the opening closed is pressed down from the surface to be elastically deformed, so that the locked state of the lid by the locking portion can be released.
Here, a flange that receives the second end portion of the lid at the slide end position from the back surface is provided projecting toward the opening at a position near the locking portion.

  In a specific aspect, the slide guide portion is formed along a slide direction of the lid at a position where both side edges of the lid toward the slide end position are to be engaged, and the locking portion is directed to the slide end position. A central portion (first end) of the front edge of the lid is provided at a position to be engaged, and the flange portion has corners (second end portions) on both sides across the central portion of the front edge of the lid. Each is formed at a position to be engaged.

  In the portable electronic device according to the present invention, when the lid is attached to the casing, both side edges of the lid are brought into sliding contact with the slide guide portions of the casing, and the lid is slid to the slide end position. When the lid reaches the slide end position, the first end of the lid is locked by the locking portion of the housing, and at the same time, the back surface of the second end of the lid is in sliding contact with the surface of the flange portion of the housing, The second end of the lid is received from the back surface by the flange. In this process, the first end portion of the lid is elastically restored after being slightly elastically deformed. However, the second end portion of the lid is pressed from the back surface by the flange portion of the housing, so that the first end portion is elastically restored. Is energized, and a large click feeling is obtained.

  When the lid is attached to the housing in this manner, the first end of the lid is locked by the locking portion of the housing, and the second end of the lid is received by the flange of the housing. As a result, resistance is exerted against the elastic deformation of the lid in the direction in which the locking by the locking portion of the housing is released. Therefore, even when an impact force is applied due to dropping or the like, the lid does not easily come off.

  When removing the lid from the housing, the lid at the slide end position is pressed at a position near the first end as in the conventional case. As a result, the first end portion of the lid is elastically displaced, and the locked state by the locking portion is released. At this time, the second end of the lid is received by the flange of the housing, but the second end of the lid is appropriately spaced from the first end, so the first end is locked. It will be displaced by the amount of displacement necessary to release Therefore, no excessive force is required to release the lock.

  According to the portable electronic device according to the present invention, the lid can be easily attached and detached, the click feeling when the lid is closed is sufficiently obtained, and the lid can be easily removed even when subjected to impact force. There is no.
