A conventional example will be described with reference to the drawings.

FIG. 7 is a perspective view showing an example of a conventional blank panel structure.

In FIG. 7, this conventional example is disclosed in
No. 04365, which discloses a blank panel 7
0 is a seat portion 7 that is slightly larger than the guide rail 102 in front of the shelf in the depth direction of the shelf.
2 and a leaf spring 75 having an L-shaped tip is fixed vertically above and below the seat portion so as to have elasticity in the vertical direction, and is fitted and fixed to the front groove of the shelf above and below the front end. The ejector 74 has the following configuration. The guide cutout in the front direction of the oval guide rail 102 has a cutout having a size that allows the front leaf spring 75 to pass therethrough. When the blank panel 70 is inserted along the guide rail 102 of the shelf, the upper and lower leaf springs pass through the oblong punched portion of the guide rail 102 and reach the protruding end of the ellipse. By further pushing, the folded portion of the leaf spring is caught on the protruding end of the oval of the guide rail 102, and a repulsive force is generated in the vertical direction and the front direction. By fixing it to the shelf by the ejector 74, it is fixed while maintaining this repulsive force.

PK1 is smaller than PKG1 when KG1a is the first embodiment.
Applies when the height direction is smaller than the G insertion direction,
There is only one blank panel 4a, and like the blank panel 4 in the first embodiment, as shown in FIGS. 3 and 4, the blank panel 4a is moved up and down using the rotation mechanism 11a as a rotation axis. It is designed to rotate.

The blank panel 4a has a guide 6a for guiding the PKG 1a when the PKG 1a is to be inserted, similarly to the upper blank panel 4. Further, when the PKG 1a is inserted using the guide 6a as a guide, the blank panel 4a is accommodated in the convex portion of the guide rail plate 3a, as in the first embodiment.

The operation and operation of the blank panel 4a are the same as those of the blank panel 4 in the first embodiment.
It is omitted because it is the same as.

Next, a third embodiment will be described.

FIG. 6 is a perspective view showing a third embodiment of the present invention.

In FIG. 6, the third embodiment is similar to the second embodiment shown in FIG.
In the case where the height is smaller in the PKG insertion direction than the PKG1 in the case of the first embodiment, only one blank panel 5a is used, and as in the blank panel 5 in the first embodiment, FIG. As shown, the blank panel 5a rotates up and down about the rotation mechanism 11b as a rotation axis. Further, it has a guide 6a for guiding when inserting the PKG 1a.

Further, when the PKG 1a is inserted by using the guide 6a as a guide, the blank panel 5a is housed in the concave portion of the upper guide rail plate 3b as in the first embodiment. I have.

The operation and operation of the blank panel 5a are the same as those of the first embodiment.
It is omitted because it is the same as.

As described above, as shown in the first, second, and third embodiments, the blank panels 4, 4a, 5, 5a are rotated by the rotating mechanisms 11a, 11b having the springs 7, and P for subrack 20, 20a or 20b
When the KG1, 1a is mounted, the guides 6, 6a are accommodated in the convex portions of the upper and lower guide rail plates 2, 2a and the concave portions of the lower, 3, 3b of the guide rail plates, and the guides 6, 6a become guide rails of the PKG1, 1a. , 1a are not mounted, a mechanism for closing the PKG insertion port is provided. Therefore, even if the PKG is mounted, no waste is generated.

When considering the form of the housing of the apparatus to which the second and third embodiments of the present invention are applied, the subrack 20a or the subrack 20b is considered.
In a case where a plurality of PKGs are stacked, it is assumed that PKGs are to be added, and in consideration of ergonomic operability at the time of adding PKGs, the subrack 20b is located at the lower side.
It is considered that it is better to form a case in which a is stacked on the upper side.

[0036]

As described above, the present invention includes the first guide rail plate of the upper plate and the second guide rail plate of the lower plate, and the first guide rail plate and the second guide rail plate. In the case of a subrack that can mount multiple packages in which electronic circuits are mounted on a printed circuit board, the package is not mounted in the subrack in units of the width of the package at the respective insertion openings of the subrack's multiple packages. A blank panel that indicates the presence of the package and closes the insertion slot. The blank panel is provided between the first and second guide rail plates, and rotates up and / or down when the package is inserted to support the package. It has a rotating mechanism that operates to automatically close the insertion slot when it is pulled out of black and has a guide to guide the insertion and removal of the package. The has the following effects.

The first effect is that it is possible to eliminate the necessity of removing and discarding the blank panel at the time of adding the PKG, and it is possible to greatly reduce the number of work steps.

[0038] The reason is that the blank panel can be opened and closed by having a blank panel rotatable in the PKG insertion slot and an elastic body in its rotating mechanism, so that the PKG can be inserted without removing the blank panel. .

The second effect is that waste can be reduced.

The reason is that by integrating the blank panel with the subrack via the rotation mechanism, there is no need to discard the blank panel when adding a PKG.
