ていた。Since the above-mentioned conventional device is a steel plate case, the rigidity thereof is high and the electrical equipment can be grounded through the steel plate case. However, there is an advantage that it can be dealt with immediately by changing the drilling process, but there is a disadvantage that the whole becomes large due to structural restrictions such as a hinge portion. In addition, a separate door closing part is required, which has caused an increase in cost. Further, since the steel plate case fixing screw is not exposed to the surface of the housing side wall because it is fastened and fixed to the inner surface side of the housing side wall, there is an advantage in terms of design. This has caused an increase in the number of assembly steps.

損されるという問題点があった。In general, if the above-mentioned case and door are made of a resin molded product, and the hinge portion and the door closing portion are integrally formed, a small-sized and inexpensive manufacturing is possible. Although the hinge portion is integrally formed of a resin molded product, a general conventional example is a practical example 2-3.
0864. In the above embodiment, the hinge shafts are integrally provided at both ends of the resin door, and the hinge shafts are fitted into bearing holes provided on the resin case side with the resin door warped. However, the workability of mounting the resin door is poor, and a resin door having a large rigidity or a hinge door having a small dimension between hinge axes further increases this disadvantage. Although the door closing portion is integrally formed of a resin molded product, there are Japanese Utility Model Publication No. 2-9569 and Japanese Utility Model Publication No. 2-14220 as general examples of the related art. In the above embodiment, a U-shaped elastic locking piece is integrally provided at the edge of the resin door, and is snap-locked to a locking portion provided on the resin case side. However, it is difficult to open the resin door by pulling the elastic lock piece while bending the elastic lock piece, and there is a problem that the elastic lock piece is sometimes broken by excessive pressing.

えるという利点がある。The hinge engagement between the resin door 28 and the resin case 21 can be made extremely simple because there is no need to warp the resin door 28, and the diameter and the engagement length of the hinge pin 32 can be made sufficiently large. . Further, since the rigidity of the resin door 28 itself can be increased, the resin door 28 can withstand severe use. Since the steel plate case 4 and the resin case 21 can be fixed by screws to the housing from the outside of the housing, workability is good. When the resin door 28 is closed, the screws 16a, 16b,
Since the head of 17 is covered with the resin door 28, it is preferable in design. In addition, the operating force of the electric equipment is less than the resin case 2.
1 does not cause damage to the resin case 21 due to excessive operation, and has the advantage that the electrical equipment can be grounded via the steel plate case 4.

良いものにできる。According to the above configuration, since the lock arm 65 for snap lock is provided on the resin case 21 side, the space in the resin case 21 (can be made larger than the door). The lock arm 65 having a large elastic force and a low bending stress (as a result, a large outer shape) can be formed by utilizing the above. Therefore, there is no decrease in elastic force due to creep,
Locking can be reliably performed against the elasticity of the packing 33 for many years. Moreover, since it is desired to be constituted by a pair of lock arms 65 having hook portions 65a of opposite directions, even if the right and left positions of the snack lock portions 61 and 62 are shifted for some reason, one hook portion 65a is more likely to be formed. It is engaged deeply and can be locked securely. The pressing of the release arm 75 can be performed in the same manner as the operation of pulling while holding the trapezoidal handle 68, and the resin door 28 is pushed up by the elasticity of the packing 33 at the same time when the hook 65a is disengaged, so that it can be opened lightly. . In addition, since the release arm 75 does not require a large elastic force, it can be formed integrally with the trapezoidal handle 68 in a small size, and the appearance can be improved.

Is limited to If the release arm 75 is expanded or twisted with the resin door 28 opened,
The release arm tip 75b abuts on the inner wall of the enlarged entrance 73, and its movement is restricted to a predetermined range. As a result, the release arm 75
The breakage due to excessive external force including mischief is prevented. The lock arm 65 is prevented from having the same problem by the surrounding wall 63. The space inside the enclosure 63 is the resin door 28

By means of the seal member 67, the electrical equipment mounting portion in the resin case 21 and the space inside the panel are closed in a dust-proof and drip-proof manner.
As described above, the snap lock portions 61 and 62 have superior operability and reliability as compared with the above-described conventional embodiment. Further, the resin case 21 and the resin door 28 are small and inexpensive because the hinge portion and the door closing portion are integrally formed.

移動が規制されている。When the resin door 28 is closed, the lock arm hook 65a of the resin case 21 comes into contact with the locking portion 83 of the resin door 28. Subsequently, the resin door 28 resists the elasticity of the packing 33.
Is pressed, the lock arm 65 is elastically deformed and the hook 6
5a enters the handle 78, and when the lower surface of the hook portion 65a reaches the surface position of the resin door 28, the hook portion 65a elastically returns, and the hook portion 65a is locked by the locking portion 83 (see the left locking arm 65 in FIG. 12). ). To release the snap lock, the pair of sliding buttons 85 are simultaneously pressed while holding the handle 78 of the resin door 28. Then, the sliding button 85 moves inward, the locking arm hook 65a is pushed, the engagement between the hook 65a and the locking portion 83 is released, and the resin door 28 can be opened (right locking in FIG. 12). See arm 65). Also, the sliding button 85
The stepped portion 87a abuts on the edge of the top 79 to restrict the inward movement.

欠点がある。The snap lock portion of the third embodiment has the same effect as that of the first embodiment. In addition, since there is no gap in the handle portion, the snap lock portion is advantageous for dust proofing and drip proofing, and is more severe. Applicable to those that can be used in the environment, handle 7
8 has a high degree of freedom in external design, such as a low height. On the other hand, there is a disadvantage that the number of parts is increased and the cost is slightly increased.

電気機器取付に使用できる。Although the lock arms 65 of the first to third embodiments are provided in a pair, substantially the same effect can be obtained by using only one lock arm. In this case, only one release arm 75 and one slide button 85 may be used. Further, in addition to the loading switch 15, for example, an on / off switch of a CRT may be provided in the mounting bracket 7 of the FDD 14. Thus, it can be used for mounting various electric devices other than those illustrated.
