[Conventional technology]

FIG. 3 is a partially exploded perspective view showing an example of a conventional device.

In Figure 3, 4 is a case with two shelf boards 1,
1, two consecutive plates 2, 2 connecting both ends of the shelf plates 1, 1, and a rear plate 3 provided at the rear ends of these plates.

Both shelf boards 1, 1 of this case 4 have a structure that can store a large number of printed circuit boards 5, for example, nine printed circuit boards 5.For example, on the inner surface of both shelf boards 1, 1, channels 13 for storing printed circuit boards 13 for storing nine printed circuit boards are arranged at required intervals. It has a structure provided in An operation display electrical component 6 and an operation electrical component 7 are provided at the front of each printed circuit board 5.

Reference numeral 10 denotes a front panel provided with windows 8 and 9 for these electrical components 6 and 7, and is attached to the front surface of the case 4. 12a is a space for storing the required number of printed circuit boards, for example, four printed circuit boards 5, in the printed circuit board storage area between both shelf boards 1 and 1, and the remaining five without any printed circuit boards 5 stored therein. This is a dustproof/insectproof backing plate with a length corresponding to the printed circuit board storage area (unmounted area), and is attached to the back surface 10a of the front panel 10, which corresponds to the unmounted area, with screws.

In such a conventional device, when adding printed circuit boards 5 several times depending on the scale of the equipment, each time the printed circuit board 5 is added, a backing board shorter than the current backing board 12a is added by a length corresponding to the number of boards to be added. That is, after the expansion, a contact plate with a length corresponding to the remaining several printed circuit board storage areas (unmounted parts) in which the printed circuit boards 5 are not stored is used, and this contact plate is attached to the front panel 10 corresponding to the unmounted parts. It is attached to the back of the

[Problem that the invention attempts to solve]

Each time the above conventional device is expanded, the current contact plate 12a
It is necessary to remove the board and replace it with a backing plate with a length equivalent to the remaining number of printed circuit board storage sections (unmounted section) on the back side of the front panel 10 corresponding to the unmounted section. The same number of extra backing plates are required, and the work of replacing the backing plates has to be repeated the same number of times as the number of additional backing plates is installed, resulting in poor work efficiency.
The problem was that it was expensive.

[Means for solving problems]

In order to solve the above-mentioned problems, the device of the present invention has a front surface of a case 4 formed using two shelf boards 1, 1 having a structure capable of storing a large number of printed circuit boards 5 as shown in the first figure. When all the printed circuit boards 5 are stored, a front puzzle 10 with windows 8 and 9 for operation display electrical components 6 and operation electrical components 7 provided on the front of each printed circuit board 5 is attached. In a printed circuit board storage device configured such that a dustproof/insect proof plate is attached to the back side of the front panel 10, the length corresponds to the unused printed circuit board storage area where no printed circuit board 5 is stored. A dust-proof/insect-proof backing plate 12 having a number of separation grooves 11 corresponding to the number of boards is prepared, and a required number of printed boards out of all the printed boards are printed in the printed board storage area between the two shelf boards 1, 1. The dust-proof and insect-proof patch plate 12 is installed on the back side 10a of the front panel 10, which is the printed circuit board storage area for the remaining number of printed circuit boards 5 that are not stored with the board 5 stored therein.
The structure is such that a length is left to cover the opening 9 and the opening is separated and attached using the cutting groove 11.

[Function] Since the device of the present invention is configured as described above, when the printed circuit board 5 is added several times depending on the scale of the device, the front panel 10 is
With the current backing plate 12 attached to the back side of the board, cut this backing board 12 to a length corresponding to the remaining number of printed circuit board storage areas (unmounted areas) in which no printed circuit boards 5 are stored after expansion. It can be separated using the cutting groove 11.

〔Example〕

FIG. 1 is a partially exploded perspective view showing an embodiment of the device of the present invention, and FIG. 2 is a perspective view of the external appearance thereof.

First, its configuration will be explained.

In FIGS. 1 and 2, parts that are the same as those in FIG. 3 are designated by the same reference numerals, and their explanations will be omitted since they are redundant.

In this embodiment, the total number of printed circuit boards is 9, for example.
An acrylic resin dustproof/insectproof plate with nine cutting grooves 11 (U-shaped or V-shaped grooves with a groove bottom thickness of 1 to 1.5 mm and a groove width of about 2 to 3 mm). Prepare the board 12, store the required number of all printed circuit boards, for example, four printed circuit boards 5, in the printed circuit board storage area between both shelf boards 1 and 1, and store the remaining five printed circuit boards 5 that are not stored. Front panel 1 corresponding to the printed circuit board storage area (unmounted area)
0, the back plate 12 is attached to the back part 10a of the back part 1.
A length that covers the windows 8 and 9 of 0a, that is, a length corresponding to the unmounted portion, is left and is separated and attached at the separation groove 11 (position shown by line A-A in FIG. 1).

Next, its effect will be explained.

When the printed circuit board 5 is not mounted, a dust-proof and insect-proof backing plate 12 (see FIG. 1) having nine separation grooves 11 corresponding to the total number of nine printed circuit boards is attached to the back side of the front panel 10. I will have to install it. When four printed circuit boards 5 are mounted as shown in the first figure, the contact plate 12 is placed along the A-A line on the back side of the front panel 10 corresponding to the unmounted part, leaving a length corresponding to the unmounted part. The window 8 of the back surface portion 10a is separated and attached at the position shown.
9 is closed, and dust and insects can be prevented from entering the case 4 through these windows 8 and 9.

When the scale of the equipment expands and the number of printed circuit boards 5 is increased from the current four, leave the current backing plate 12 attached and partially remove the mounting screws of the backing plate 12 as necessary. can be separated using the separation groove 11, leaving a length corresponding to the unmounted part after expansion. In the same way, every time an extension is made, the backing plate 12 is separated using the cutting groove 11, leaving a length corresponding to the unmounted part after the addition, so that all mounting forms can be easily handled.

[Effect of idea]

As described above, according to the present invention, the cutting groove 11
Since the dust-proof/insect-proof backing plate 12 with a Since it is possible to easily deal with all implementation forms by separating the
Only one backing plate 12 is required, and there is no need to reattach the backing plate 12, which not only improves work efficiency but also enables inexpensive implementation. In addition, when the printed circuit board is reduced, the separated backing plate will correspond to the front panel 1.
It can be used to close windows 8 and 9 of 0.

It goes without saying that the present invention can be widely applied to a backing plate for closing a window on a front panel of a device in which the number of mounted parts must be increased or decreased depending on the scale of the device.
