With the above structure, the door member is rotatably supported by the housing body via the support shaft. When the door member is closed with respect to the housing body, the through hole is located between 0 o'clock and 3 o'clock of the timepiece. Since the stopper pin is installed in the three o'clock direction with respect to the support shaft, one end of the through hole is close to the stopper pin.

On the other hand, when the door member is opened at an angle of approximately 90 degrees clockwise with the support shaft as the center of rotation, the through hole is located in the range of 3 o'clock to 6 o'clock of the timepiece. .
Therefore, the other end of the through hole comes into contact with the stopper pin. As a result, the door member can no longer be opened, and the opening angle is restricted to a predetermined value.

According to the second aspect of the present invention, there is provided a housing body for housing the electronic device and a door member for closing the release surface of the housing body, the door member being the upper and lower portions on one end side of the housing body. In a housing of an electronic device, which is openably and closably supported through a support shaft mounted on the door and a support shaft hole formed in the door member, a stopper pin is provided at a predetermined position near the support shaft on the door member side. The configuration is such that a through hole for inserting the stopper pin is formed at a position corresponding to the stopper pin of the housing body. Even with the above configuration, the same operation and function as the invention according to claim 1 is achieved.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described with reference to FIGS.

First, as shown in FIG. 1, the electronic device housing comprises a housing body 20 for housing the electronic equipment and a door member 24 for closing the release surface of the housing body 20.
A support shaft 4 is openably and closably supported via a support shaft 3 provided on the upper and lower portions of one end of the housing body 20 and a support shaft hole 7 formed in the door member 24. A stopper pin 4 is provided at a predetermined position near the support shaft 3 on the housing body 20 side, and a through hole 8 for inserting the stopper pin 4 at a position corresponding to the stopper pin 4 of the door member 24. Are formed.

To explain the above in detail, the housing body 20 is formed in a predetermined cube so that an electronic device can be mounted therein. A wall surface is not provided on the front surface of the housing body 20 and is an open surface. this is,
This is because the electronic device can be carried in and installed in the housing body 20, and maintenance and inspection can be performed.

A predetermined door member 24 that covers the entire release surface is installed at a position corresponding to the release surface of the housing body 20. The door member 24 is normally closed during use in order to protect the electronic device inside the housing body 20. Then, it can be opened and closed for maintenance and inspection by an opening / closing mechanism described later.

Next, the opening / closing mechanism of the door member 24 will be described in more detail. First, as shown in FIG. 1, a housing-side hinge having a shape as shown in FIG. 1 is provided. This housing side hinge 1 is
Similarly, the door member 24 is rotatably supported in cooperation with a housing-side hinge (not shown) also provided at the upper end of the housing body 20.

As shown in FIG. 2C, the housing side hinge 1 is made of a plate member having an L-shaped cross section, and fixing holes 2 for fixing to the housing body 20 are provided at predetermined intervals on the vertical surface side. A plurality of them are formed at intervals. The fixing hole 2 is provided on the housing side hinge 1.
It is formed with an elongated hole so that the position of can be finely adjusted.
Here, the housing side hinge 1 is formed in an L shape so that the vertical surface side is fixed to the housing body 20 as described above, but the shape is not limited to this, and the housing body 2 is not limited thereto.
The shape does not matter as long as the horizontal plane can be projected from 0.

The door member 2 is provided at a predetermined position on the horizontal surface side.
A cylindrical support shaft 3 for rotatably supporting 4 is installed with its central axis oriented in the vertical direction. Here, the predetermined position is the left end of the housing-side hinge 1 in this embodiment. Then, when the housing-side hinge 1 is fixed to the housing body 20, the housing-side hinge 1 is positioned so as to be on a substantially extended line of the side surface of the housing body 20. The support shaft 3 is press-fitted into a predetermined installation hole formed in the housing side hinge 1. A predetermined flange is formed on the outer peripheral portion of the support shaft 3 so as to maintain a predetermined height with respect to the housing side hinge 1. Here, the predetermined height is a height that is not easily removed when the door member 24 is fitted, as described later.

Further, a cylindrical stopper pin 4 is also disposed near the support shaft 3 (to the right in FIG. 2). The stopper pin 4 is for regulating the opening angle of the door member 24 as described later, and is installed with its central axis oriented in the vertical direction, like the support shaft 3. Further, the stopper pin 4 is also installed by press fitting, but unlike the case of the support shaft 3, the stopper pin 4 is inserted from below the housing side hinge 1. This is because the stopper pin 4 can be installed and removed even when the door member 24 is installed on the housing body 20. Further, in the vicinity of the stopper pin 4, a pin installation hole 4a for inserting another stopper pin is formed. The pin installation hole 4a is provided so that the opening angle of the door member 24 can be arbitrarily regulated by replacing the stopper pin 4. That is, the pin installation hole 4a is formed on the same radius as the stopper pin 4 with the support shaft 3 as the radial center.

Next, the door-side hinge 5 installed on the door member 24 side will be described with reference to FIG. The door-side hinge 5 cooperates with the housing-side hinge 1 described above, and the door member 24.
Is rotatably supported and is formed of a substantially rectangular plate member. And this door side hinge 5
Has a width and a length set so as to substantially overlap with the horizontal surface side of the housing-side hinge 1 when properly assembled. Further, a support shaft hole 7 is formed in the door side hinge 5 at a position corresponding to the support shaft 3 of the housing side hinge 1 described above. The support shaft hole 7 has an inner diameter slightly larger than that of the support shaft 3 in order to make the door member 24 rotatable.

A through hole 8 for inserting the stopper pin 4 is formed near the support shaft hole 7. The shape of the through hole 8 is an arc shape with the support shaft hole 7 as the radial center, the width thereof is slightly larger than the diameter of the stopper pin 4, and the length thereof is approximately a quarter circle. Has become. Here, the through hole 8 is formed in an arc shape, but the shape is not limited to this, and if the positions of both ends (above and to the right of the support shaft hole 7) are the same, then The shape does not matter. This is because, as will be described later, the opening angle of the door member 24 is restricted only by the positional relationship between the stopper pin 4 and the end of the through hole 8.

A predetermined fixing hole 6 is formed on the right side of the through hole 8 of the door side hinge 5. This fixing hole 6
Is for fixing the door-side hinge 5 to the door member 24, and rivets and screws are inserted therein. Here, in this embodiment, the door member 24 has a flat plate shape to be fixed to the door member 24 with screws or rivets. However, when the door member 24 is fixed by another method such as welding, another shape can be used. is there.

First, two screw holes are formed on the front surface of the bottom plate of the housing body 20 at predetermined intervals. The screw holes are positioned so as to correspond to the fixing holes 2 formed in the housing side hinge 1. And. The vertical surface side of the housing side hinge 1 is attached to the front surface of the housing body 20 described above, and is mechanically fixed by the screw member 9. As a result, both the support shaft 3 and the stopper pin 4 are fixed with their central axes in the vertical direction.

On the other hand, the door-side hinge 5 is fixed to the lowermost surface of the door member 24. Specifically, the door-side hinge 5 is horizontally fixed to the door member 24, and the support shaft hole 7 is provided in the housing main body 20.
It will be installed facing sideways. Then, at the position corresponding to the support shaft hole 7 and the through hole 8 on the lowermost surface of the door member 24,
A predetermined cutout 24a is formed. The notch 24a is for inserting the support shaft 3 and the stopper pin 4 into the support shaft hole 7 and the through hole 8, and has a sufficient area.

The above-described structure is applied to the housing main body 2
It is also provided at the top of 0 (not shown). That is, at the uppermost portion, a support shaft (not shown) is arranged vertically downward, and an extension line of its central axis is aligned with the support shaft 3 arranged at the lowermost end. Therefore, when the support shaft 3 and the stopper pin 4 are inserted so as to correspond to the support shaft hole 7 and the through hole 8, the door member 24 is rotatably supported with respect to the housing body 20.

Further, as described above, the support shaft 3 and the stopper pin 4 are disposed on the housing side hinge 1 of the housing body 20, and
