Abstract

PURPOSE:To easily and simply mount the display plate on a substrate by fitting the display plate temporarily on the substrate with static electricity generated when a protection sheet on the surface of the display plate is peeled, sliding the display plate until the display plate abuts on projections for positioning, and fixing the display plate with a fixing member. CONSTITUTION:The display plate 5 is made of synthetic resin which easily generates the static electricity in a plate shape and the protection sheet 17 which covers a print surface is fitted on the surface so that the sheet can be peeled. Then when the sheet 17 is peeled off the display plate 5, the display plate 5 is attracted and fixed temporarily on the substrate 4 with the static electricity due to friction. Then the display plate 5 is slid and positioned by making the lower edge abut on projections 8 and 9 and one edge abut on projections 10 and 11. In this state, rivet type fixing members 12 are inserted into receiving holes 18 - 21 and 13 - 16 to fix the display plate. Consequently, the display plate can easily and simply be fitted at the correct position on the substrate.

A display plate 105 for adjustment is affixed to the outer surface of the shield plate 104, and the display plate 105 displays the positions of the various knobs 10l...101. from the outside of the PCBl
The knob 02 can be operated reliably and easily.

[Problems to be solved by the invention By the way, the above-mentioned conventional display plate for adjustment! 05 is the 4th
As shown in the figure, an adhesive layer 107 is provided on one side of the resin film 106, and a release paper 108 is attached to the adhesive layer IO7 to form a seal. Since the resin film 106 was peeled off and the resin film 106 was attached to the outer surface of the shield plate 104 using the adhesive layer 107, there were problems as described below.

(1) Peel off the release paper lO8 and you will see a resin film! 06 becomes curled, making it difficult to paste.

(2) When pasting, so-called positional displacement is likely to occur, and if positional displacement occurs, it is troublesome to reapply.

(3) Wrinkles and bubbles are likely to occur when pasting.

(4) Resin film with adhesive layer 107 without causing wrinkles! Even if 06 is attached to the shield plate 104, when the shield plate 104 gets hot, the adhesive layer 107
The resin film 106 may peel off or the resin film 106 may expand, causing wrinkles.

The present invention has been made for the purpose of solving the above-mentioned conventional problems and providing a method for simply and easily attaching a display plate to a substrate of a shield plate.

[Means for solving the problem] The display board is formed into a plate shape using a synthetic resin that easily generates static electricity, and a protective sheet covering the printed surface is removably attached to the surface of the display board to protect the display board. After the display board is temporarily attached to the substrate by adsorption with static electricity generated when the sheet is peeled off, the display panel is permanently attached to the substrate using fixing members such as rivets.

Further, the substrate is provided with a projection for positioning the display board,
With the display board positioned by the protrusions, the display board is permanently fixed to the substrate using a fixing member such as a rivet.

[Operation: When the protective sheet covering the printed surface of the display board is peeled off, static electricity is generated on the display board due to the frictional force at that time, and the display board is temporarily attracted to the base by the energy of the static electricity, resulting in a so-called temporary fixation. be in a state of being

Also, with the display board attached to the board, if you slide the display board along the surface of the board, the peripheral edge of the display board will come into contact with the projections for positioning the display board, and the display board will be positioned. become.

Therefore, the display board can be positioned using the projections for positioning the display board, and the display board can be fixedly attached to the substrate using a fixing member such as a rivet while being temporarily fixed by static electricity.

[Example] Next, a method for attaching a display board according to the present invention will be described by taking as an example a case in which a shield that also serves as a heat sink as a substrate and a display board for adjusting a knob are attached to a display monitor.

In Figs. 1 and 2, ■ is a display monitor, and a board 4 serving as a shield and heat sink plate is placed outside the PCB 3 on which various knobs 2, such as a volume knob, etc. are provided. A display board 5 is attached to the outer surface. The board 4 and the display board 5 each have various knobs 2...2 on the PCB 3.
Adjustment holes 6...6 and adjustment holes 7...
- 7 are provided, and the display board 5 is attached to the outer surface of the substrate 4 with these adjustment holes 6...6 and 7...7 superimposed on each other.

The board 4 is made of metal such as aluminum alloy and has a rectangular shape, and covers the outside of the PCB 3.
It is attached to the cabinet of the display monitor l, and on its surface there are first to fourth protrusions 8 for positioning the display board for overlapping the adjustment holes 6...6 and 7...7 with each other. ~1l is formed protrudingly.

Said first to fourth protrusions 8~! 1 is arranged in the shape of a hook (''), and the 1st and 2nd protrusions 8.9 position the display board 5 in the vertical direction, and the 3rd. The fourth projections 10.11 are used to position the adjustment holes 7...7 in the left and right directions to match the adjustment holes 6...6 of the substrate 4, and
First to fourth fixing member holes 1 for fixing the aligned four corners of the display board 5 with fixing members l2 such as rivets.

The display board 5 is made of a heat-resistant synthetic resin such as polycarbonate and has a rectangular plate shape like a so-called underlay, and has a print on its surface for displaying the knobs 2...2 of the PCB 3. The printed surface is covered and protected with a removable protective sheet l7, and the four corners are provided with first to fourth fixing member receiving holes 13 provided in the base 4. - Fifth to eighth fixing member receiving holes 18 to 21 are formed to overlap I6.

The fifth fixing member receiving hole 18 is formed as a circular hole, and the remaining sixth to eighth fixing member receiving holes 19 to 2l are long holes extending toward the fifth fixing member receiving hole l8. The sixth to eighth fixing member receiving holes 19 to 2l, which are elongated holes, absorb expansion and contraction of the display board 5 due to heat.

Also the aforementioned fixing member! 2 is formed of nylon into a rivet shape having a head and a shaft portion, and is designed to integrally connect the display plate 5 to the substrate 4 in a state where they are superimposed.

The embodiment has the above-mentioned configuration, and when the protective sheet 17 is peeled off from the display board 5, static electricity is generated due to the friction. It is naturally adsorbed to the base 4 and becomes temporarily fixed.

Therefore, with the display board 5 adsorbed to the board 4, the board 4 is
The lower edge of the display board 5 is brought into contact with the first and second protrusions 8 and 9, and the display board 5 is slid along the surface of the display board 5.
One side edge of the third. When brought into contact with the fourth protrusion 10.11, the display board 5 is positioned, and the adjustment holes 7...7 of the display board 5 and the adjustment holes 6...6 of the substrate 4 overlap each other. Also, the fifth to eighth fixing member receiving holes 18 to 2l of the display board 5 and the first to fourth fixing member receiving holes 13 to of the substrate 4 are in the same state. 6 are overlapped with each other.

Therefore, the first to fourth fixing member receiving holes 18 to 21 and the fifth to eighth fixing member receiving holes l3 to l overlap each other.
By inserting the rivet-like fixing members [2...I2] into the four corners of the display panel 5, the four corners of the display panel 5 are firmly fixed to the substrate 4 by these fixing members l2...12.

If the display board 4 expands or contracts due to heat, it will be absorbed by the sixth to eighth fixing member holes 19 to 2I of the long bow,
The display board 4 is maintained in a straight extended state.

Note that the embodiment shown in the drawings shows the case where the adjustment display plate 5 is attached to the substrate 4 as a shield plate in a display monitor, but the mounting method of the present invention is not limited to the embodiment and can be applied to a wide range of display plates. This includes the case where it is attached to a substrate as a display board support.

[Effects of the Invention] Since the display board mounting method of the present invention has the configuration as described above, it has the following effects.

(1) Use the frictional force when peeling off the protective sheet covering the printed surface of the display board to generate static electricity on the display board, and use the static electricity to attract the display board to the board and temporarily fix it. The display board can be permanently fixed to the board using a fixing member such as a rivet (if the static electricity is too weak to simply peel off the protective sheet, it is sufficient to rub the display board).

(2) The display board can be easily positioned by bringing the peripheral edge of the display board into contact with a display board positioning protrusion protruding from the surface of the substrate.

(3) After positioning the display board using the display board positioning protrusions and temporarily fixing the display board using static electricity, the display board can be permanently fixed to the substrate using a fixing member such as a rivet.
