Here, the display unit 12 is a unit made by electrically arranging a large number of display elements 11 on the front surface as shown in FIG. It has the function of forming designs etc.

Each display unit storage frame 10 is provided with a plurality of slot portions 13 in a vertical row corresponding to the external shape of each display unit 12, and each display unit 12 can be attached to and removed from each of the slot portions 13. It is freely configured.

That is, to assemble the display unit 12 into the slot portion 13, the display unit 12 is inserted into the slot portion 13, and the mounting holes 14a of the mounting members 14 provided at the top and bottom of the back surface of the display unit 12 are inserted into the slot portion 13. After aligning the mounting hole 13a provided in the
This can be easily done by fitting the pin 15 into the holes 14a and 14a. Conversely, in order to remove the display unit 12 from the slot portion 13, the pin 15 may be removed and the display unit 12 may be pulled out toward the front.

It should be noted that since the display unit storage frame 10 is capable of storing a plurality of display units 12 in a vertically integrated manner as described above, the load on the lower side is larger than that on the upper side. Therefore, if the component structure of the lower part of the display unit storage frame 10 is reinforced, the upper part can be made of a lightweight material, which is advantageous in reducing the weight and cost of the display unit storage frame 10 as a whole. can be achieved.

On the other hand, the mounting frame 20 has a front fixing bar 21a.
A plurality of arrays (four rows in the drawing) of the rear fixed rods 21b assembled to the pedestal 22 are arranged, and each of these fixed rods 21a, 21b
It is constructed by incorporating auxiliary frames 23a and 23b into the.

[0021] The front fixed bar 2 constituting the mounting frame 20
An upper bracket 24 and a lower bracket 25 are fixed to 1a by fastening members 26a and 26b in correspondence with the height of the display unit storage frame 10.

Support members 27a, 27b are arranged on the front surface of each bracket 24, 25, and each display unit storage frame 10 is provided with support members 27a, 27b.
Upper bracket 24 and lower bracket 25 via 7b
It is configured so that it can be installed between

When assembling the electronic display device having the above configuration, first insert the display units 12 into the slot portions 13 of each display unit storage frame 10, and insert the pins 15 into the respective mounting holes 13a and 14a. By this,
Display unit storage frame 10 with display unit 12 attached
(hereinafter referred to as a vertically integrated structural unit in this embodiment) is prepared.

The vertically integrated structural unit formed in this manner has a size sufficient to be loaded onto a transportation vehicle such as a truck, so it can be transported with each display unit 12 attached. It is possible to provide

Next, the plurality of vertically integrated structural units are sequentially installed in the horizontal direction to the mounting frame 20 that has been assembled in advance.

That is, each of the vertically integrated structural units is inserted between the upper bracket 24 and the lower bracket 25 on the front surface of the mounting frame 20, and the supporting members 27a, 27
Bolts 28b are inserted into the upper and lower mounting holes 10a and 10b of the display unit storage frame 10 through the mounting holes 27c and 27d of b.
