Since the work of connecting the conductive pin to the power supply line on the power source side can be performed only after the conductive transparent body is supported on the pedestal, soldering (or screwing or the like) in the pedestal is performed.

In addition to being formed from a metal element wire such as a silver wire, a zinc wire, and a stainless wire, it is formed by depositing or plating a metal on the surface of a resin element wire such as a polyester wire.

The electrically insulating wire 14 is also formed of an ultrafine wire having a diameter or a width of 0.1 mm or less. The element wire is formed of resin element wire such as polyester wire and nylon wire.

That is, since the conductive transparent body 1 uses ultrafine element wires as the conductive wires 13 and the electric insulating wires 14 which form the conductive mesh, the whole looks like an achromatic or chromatic transparent body. . The interval between the adjacent conductive lines 13 and the interval between the adjacent electrically insulating lines 14 are set in consideration of the transparency of the viewer. For example, a conductive wire 13 with a diameter of about 0.1 mm

The light bulb 4 is provided at the edge of the base portion 11 opposite to the portion where the hole 16 is provided, and is arranged so as to indicate an arrow as shown in FIG. 1, for example. Further, each of the light bulbs 4 has both positive and negative terminals independently connected to the conductive wires 13 of the conductive transparent body 1, and is supplied with power by these conductive wires 13. At this time, the conductive wire 1 of the conductive transparent body 1
3 may be used as an independent power supply line, or may be used as a power supply line bundle that allows a relatively large current to flow by converging a plurality of conductive wires 13 at their terminals. When connecting both the positive and negative terminals of the light bulb 3 to the conductive wire 13 of the conductive transparent body 1, the base portion 1
It is possible to expose the conductive wire 13 by making a hole in 1 or removing the base portion 11 with a solvent and connecting it by soldering or the like.

A power supply unit 4 connected to an external power source is provided in the pedestal 2. The power feeding unit 4 includes a control circuit that controls a display state such as a lighting order of the light bulbs 3 of the conductive transparent body 1.

Then, each conductive wire 1 of the conductive transparent body 1
3 and the power supply line 25 of the power supply unit 4 on the power supply side are connected to the connector 5
Is connected in the pedestal 2 via a connector socket 6.

The connector 5 is fixed in the recess 21 of the conductive transparent body 1 and is accommodated within the thickness of the conductive transparent body 1. Further, the connector 5 is locked to the step 17, so that a stable fixed state is obtained without using an adhesive agent. The connector 5 has a plurality of terminals 51, and each terminal 51 is inserted into the hole 16 of the conductive transparent body 1 and connected to the conductive wire 13.

The connector socket 6 is fixed in the pedestal 2 and is connected to the power feeding line 41 of the power feeding section 4.

The connector 5 and the connector socket 6 are provided in a position and an orientation in which they can be connected at the inserting position of the conductive transparent body 1 and can be cut off at the pulling-out position of the conductive transparent body 1.

That is, in the above display device, the electric power supplied from the power feeding section 4 is applied to each light bulb 3 through the conductive wire 13 in the conductive transparent body 1, and each light bulb 3 lights up to display an arrow. To be done. At this time, based on the lighting control of the control circuit, the light bulbs 3 can be sequentially turned on from the end, and finally all the light bulbs 3 can be blinked.

Further, according to this display device, it is possible to produce the unexpectedness that the light bulb 3 is lit in the transparent space provided by the conductive transparent body 1, and the conductive wire 1 is provided in the transparent space.
Since there is no recognition that 3 exists, it is possible to provide a neat design.

Next, the operation of this embodiment will be described.

First, the procedure for supporting the conductive transparent body 1 on the pedestal 2 will be described.

First, each terminal 51 of the connector 5 is inserted into the hole 16 formed in the recess 15 of the conductive transparent body 1 to fix the connector 5 in the recess 15 of the base 11. Then, each terminal 51 of the connector 5 and the conductive wire 13 of the conductive transparent body 1 are independently connected (see FIG. 5).

Then, the edge of the conductive transparent body 1 to which the connector 5 is thus fixed is inserted into the recess 21 of the pedestal 2. Here, since the connector 5 and the connector socket 6 are provided in positions and orientations that allow connection at the insertion position of the conductive transparent body 1, the conductive transparent body 1 is inserted into the recess 21 of the pedestal 2 and at the same time the connector 5 is inserted. And the connection of the connector socket 6 are completed (see FIG. 6).

In this way, when the conductive wire 13 of the conductive transparent body 1 and the power supply line 41 on the power supply side are connected via the connector 5 and the connector socket 6, a large number of conductive wires 13 are collectively connected on the power supply side. The conductive transparent body 1 can be connected to the power supply line 41, and the connection between the connector 5 and the connector socket 6 is completed at the same time when the conductive transparent body 1 is inserted into the recess 21 of the pedestal 2. It is possible to complete the work of connecting the line 13 and the power supply line 41 on the power supply side. Therefore, by transporting the conductive transparent body 1 and the pedestal 2 separately packaged, the transport efficiency can be improved. Further, it is not necessary to secure a space for accommodating the cord pool or a work space for the wiring work in the pedestal 2, so that the pedestal 2 can be made compact accordingly.

Further, since the connector 5 is housed within the thickness of the conductive transparent body 1, even if the conductive transparent body 1 is inserted into the recess 21 of the pedestal 2 with the connector 5 still attached, the conductive transparent body 1 It is possible to prevent a gap from being formed between the dent 2 and the recess 21 of the pedestal 2. When the connector 5 projects from the conductive transparent body 1, after inserting the conductive transparent body 1 into the recess 21 of the pedestal 2, a work for closing the gap between the base portion 11 and the recess 21 is performed. It is necessary to insert the conductive transparent body 1 into the recess 21 of the pedestal 2 and then attach the connector 5 to the base portion 11 of the conductive transparent body 1 in the pedestal 2.

Next, when exchanging the conductive wire transparent body 1 for after-maintenance or the like, the conductive transparent body 1 is pulled out from the recess 21 of the pedestal 2. Here, since the connector 5 and the connector socket 6 are provided in a position and an orientation where the conductive transparent body 1 can be cut and released at the pulling-out position, the connector 5 and the connector 5 are simultaneously pulled out from the recess 21 of the pedestal 2. Then, the connector socket 6 is cut off.

In this way, since the conductive transparent body 1 can be pulled out from the recess 21 of the pedestal 2 and the connector 5 and the connector socket 6 can be cut off at the same time, the conductive transparent body 1 can be replaced very easily. .

The embodiment of the present invention has been described in detail above with reference to the drawings. However, the specific structure is not limited to this embodiment, and there are design changes and the like within the scope not departing from the gist of the present invention. Also included in the present invention.

For example, in the embodiment, the display device for displaying the arrow has been described as an example, but the content to be displayed is not limited to the embodiment and may be used as a lighting fixture.

In the embodiment, a light bulb is provided as a power supply target of the conductive wire of the conductive transparent body.

Further, the hole formed in the base portion for connecting the connector does not have to penetrate the base portion, and may have a depth such that the end face of the conductive wire is exposed on the inner surface.

Furthermore, in the embodiment, the display device is shown in which the edge of the conductive transparent body is supported by the pedestal, but the middle part of the conductive transparent body may be supported by the pedestal.
