Separately from this, in order to attach a lid or the like to the casing body without using screws in a casing of an electronic device or the like, there is provided elastic locking means composed of a locking piece having elasticity and a locking hole. What is provided is, for example, Japanese Patent Laid-Open No. 3-8396.
It is conventionally known as described in JP-A-3-91297.

[0004]

Since the housing of the conventional electronic device shown in FIG. 7 fixes the front housing and the rear housing by screwing as described above, screws are required,
Not only is the number of parts increased, but the screwing work is complicated, and assembly takes time. Further, the elastic locking means as shown in the above publications cannot provide sufficient strength against external force such as a drop impact, and the locking parts are removed at a plurality of positions in order to remove the lid or the like from the casing body. At this time, there is a problem that workability is poor because it is necessary to continue applying force to each locking portion.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an effective fixing structure utilizing elastic locking means in a housing of an electronic device.

Further, according to the present invention, a plurality of housing elements in a housing of an electronic device can be fixed without using screws.
In addition, the purpose is to obtain a sufficient fixing strength.

Further, according to the present invention, a plurality of housing elements in a housing of an electronic device are fixed by using elastic locking means, and the locking portion is once removed when the fixing is released and the housing is removed. The purpose is to improve workability without having to continue to apply force.

[0008]

SUMMARY OF THE INVENTION According to the present invention, each housing element of a housing of an electronic device in which a plurality of housing elements are fixed to each other is sufficiently fixed without using screws. As means for fixing so as to obtain strength, a rigid fitting portion for fixing in two orthogonal directions and an elastic locking portion for fixing in one other direction orthogonal to the two directions are provided.

Further, according to the present invention, in a housing of an electronic device in which a plurality of housing elements are mutually fixed by a fixing means including an elastic locking portion, when the housing is released and the housing is removed, In order not to continue to apply a force to the locking portion, a temporary fixing portion is provided that allows the housing elements to be temporarily fixed to each other with the elastic locking portion released.

[0010]

According to the first aspect of the present invention, the housing elements constituting the housing are fixed to each other by the rigid fitting portions in the two directions orthogonal to each other, and in the other direction orthogonal to the two directions. It is fixed by the elastic locking part. At that time, the fixing in two directions by the rigid fitting portion and the fixing in another direction by the elastic locking portion can be simultaneously performed by the fitting operation in the same direction as the fixing direction of the elastic locking portion. Further, since each housing element is fixed in two directions by the rigid fitting portion, sufficient strength against external force such as drop impact can be obtained in these two directions, and no deviation occurs in these two directions. This prevents an impact load or the like from being applied to the elastic locking portion. Further, even in the remaining one direction, it is possible to obtain sufficient strength against external force by setting the shape of the elastic locking portion.

According to the second aspect of the present invention, the housing elements constituting the housing are fixed to each other by fixing means including elastic locking portions, and when the fixing is released to remove the housing element. It is possible to temporarily fix the housing elements to each other by the temporary fixing portion in a state where the elastic locking portion is unlocked so that it is not necessary to continue to apply a force to the once unlocked locking portion.
