2. Description of the Related Art As shown in FIGS. 3 (a) and 3 (b), for example, a conventional case for a small
And a lid 22. Holes 22 a for inserting screws 23 are formed at four corners of the lid 22. Bosses 24 are formed at the four corners on the case body 21 side, and screw holes 24a are formed in these bosses 24. When the lid 22 is fixed to the case body 21, the screws 23 are inserted into the holes 22a. And screw hole 2
4a.

[0003]

In the case of a small electronic device case, it is necessary to secure as much volume as possible in the case.
3, the boss 24 for screwing the screw 23 overhangs inside the case body 21.
There is a problem that the volume inside the case body 21 is considerably reduced.

The present invention has been devised in view of such a problem, and even when a small electronic device is downsized and the case for the small electronic device is further downsized, a sufficient internal volume of the case is ensured. It is an object of the present invention to provide a case for a small electronic device capable of performing the above.

[0005]

In order to achieve the above object, a case for a small electronic device according to the present invention is a case for a small electronic device comprising a case body and a lid, wherein the lid is a lid body. And a rotating body rotatably attached to the lid body, and a locking plate fixed to the rotating body, and a locking portion is formed on an outer peripheral portion of the locking plate. on the other hand,
A receiving portion for locking the locking portion is formed at an upper portion of an inner peripheral surface of the case main body.

[0006]

According to the above construction, in a case for a small electronic device having a case body and a lid, the lid is a lid body, and a rotating body rotatably attached to the lid body.
A locking plate fixed to the rotating body, wherein a locking portion is formed on an outer peripheral portion of the locking plate, and the locking portion is locked on an upper inner peripheral surface of the case body. Since the receiving portion to be formed is formed, the lid is fixed to the case main body without using a screw, and it is not necessary to form a boss for fixing the screw, which takes up a volume, on the case main body side. Is sufficiently secured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 10 denotes a case for a small electronic device. The case 10 for a small electronic device includes a case main body 11 and a lid 12 made of resin. The case body 11 has a rectangular parallelepiped shape or a cubic shape with an open upper surface, and a receiving portion 11a of a locking portion 14a to be described later inwardly is formed at the center upper end of each inner surface. A stopper 11b is formed at one end of the receiving portion 11a in a hook shape.

The lid 12 has a disk-shaped rotating body 13 rotatably attached to the center of a resin-made lid body 12a having a substantially flat plate shape.
A locking plate 14 made of steel, which is rotated together with the locking plate 1, is fixed by screws 15.
4 with an appropriate frictional force. A circular concave portion 12b is formed at a predetermined portion of the portion of the lid body 12a covered by the locking plate 14, and an oval concave portion 12c is formed near the circular concave portion 12b. On the other hand, on the outer peripheral portion of the locking plate 14, locking portions 14a protruding outward at four locations are formed at equal intervals,
Further, on the side surface of the lid main body 12a of the locking plate 14, a dowel 14b that fits into the circular concave portion 12b at the time of locking and into the oval concave portion 12c before locking is provided.

As shown in FIG. 2A, in the small electronic device case 10 before locking, the locking portions 14a of the locking plate 14 are locked to the receiving portions 11a formed on the case main body 11, respectively. The lid body 12 is not
Placed on top. At this time, the dowel 14b is fitted in the oval-shaped recess 12c as shown in FIG. When the lid 12 is locked to the case body 11 side, the rotating body 13 is rotated in the direction of the arrow a in FIG. 2A, and the locking plate 14 is locked as shown in FIGS. 1A and 1B. Is locked to the receiving portion 11a formed on the case main body 11, and the lid 12 is fixed to the case main body 11 side. At this time, the rotation angle is defined by the stopper 11b so that the rotating body 13 does not rotate too much and the locked state between the locking portion 14a and the receiving portion 11a is not released. At this time, the dowel 14b is
As shown in (c), the engagement of the engaging portion 14a with the case body 11a is not released as long as the engaging portion 14a is fitted into the circular concave portion 12b and a large reverse rotation force is not applied.

As described above, according to the small electronic device case 10 according to the embodiment, the lid 12 is fixed to the case main body 11 without forming a screw fixing boss that takes up a volume on the case main body 11 side. , Space-saving case body 11a
And the locking plate 14, and the internal volume of the case can be sufficiently secured. Therefore, even when the electronic device case 10 is downsized, it is possible to sufficiently secure the internal volume of the case.

[0011]

As described in detail above, a small electronic device case according to the present invention is a small electronic device case including a case body and a lid, wherein the lid is a lid body, and the lid is The case main body includes a rotating body rotatably attached to the main body and a locking plate fixed to the rotating body, and a locking portion is formed on an outer peripheral portion of the locking plate. Since the receiving portion for locking the locking portion is formed at the upper part of the inner peripheral surface of the portion, the lid is fixed to the case main body, and a screw fixing boss for taking up volume is formed on the case main body side. And the inner volume of the case can be sufficiently secured. Therefore, even when the case for a small electronic device is further downsized, it is possible to sufficiently secure the internal volume as the case.
