摩耗するなどの問題点があつた。(Prior art) Conventionally, covers for operation panels in OA equipment such as facsimile machines have either utilized the cover's own weight as a holding mechanism when the cover is opened, or locked using parts such as springs. There are some that use the elasticity of plastic as a lock. However, all of them have problems such as unstable holding positions, increased number of parts, and wear of sliding parts.

ようにしたものである。(Structure of the invention) In order to achieve the above object, the invention provides a locking pawl and a rotating shaft integrally with the panel cover, and a locking protrusion on the receiving side of the cover and a long shaft as a rotating bearing of the cover. A circular hole is provided, and when the cover is opened, the rotating shaft of the cover moves along the oval bearing hole, and the claw and the protrusion are engaged by their own weight.

As shown in the figure, a rotating shaft 1a is provided on both sides of the end of the cover 1, and an elastic locking pawl 1b is integrally provided at the end. on the other hand,
An oval bearing hole 2a is installed at an angle in the cover receiving part 2 as a bearing for the rotating shaft 1a, and
A protrusion 2b is provided on the inner bottom surface of the protrusion 2b, which contacts and engages the lock pawl 1b. When the cover 1 is opened in the direction of arrow A, the shaft side end of the cover 1 rotates in the direction of arrow B. Then, as shown in FIG.
While contacting point b, it is simultaneously pushed up in the direction of arrow C through the ellipse.

大きな効果が得られる。(Effects of the invention) As explained in detail above, the present invention has a locking pawl on the panel cover and an oblique bearing hole on the cover receiving part, so that the locking function of the conventional locking mechanism, which relies only on the cover's own weight, can be avoided. Compared to a mechanism, the instability of the lock becoming unlatched due to external force is eliminated, and the number of parts such as springs can be reduced by forming the lock mechanism integrally with the cover and the cover receiver. In addition, the bearing of the cover receiving part is made into an oval shape so that the center of rotation can be moved.
Excessive contact force is prevented between the lock pawl and the opposing lock portion from the contact state to the lock state, and as a result, wear due to sliding of the same portion is significantly reduced. Moreover, since the present invention is simply a means of achieving the state when a single cover is opened, it can be used as a hopper for manuscripts or recording paper in facsimile machines, or as a cover for windows for replacing fluorescent lights in facsimile machines, etc. can also have a great effect.
