Since it is pressed in the state, as shown in (b) of FIG. 4, it is elastically protruded, and the LED module 300 is protruded forward as the pressing button portion 350 is elastically protruded. At this time, the LED module 300 is maintained at a predetermined interval without being separated from the main frame 100 by the magnet 330 coupled to the end of the pressing button unit 350 even in a state of elastically projecting forward. .

As described above, when the corresponding LED module 300 protrudes forward, as described above, the operator can perform the replacement operation of the LED module 300 by pulling out the corresponding LED module 300 using a hand or a tool. Can be.

In this case, unlike the description of FIG. 3, there is no need to open the opening / closing door 210 of the outer case 200, and only one operator presses the corresponding LED module 300 in front of the electronic display board. Since it can be extracted by protruding (300), it is possible to perform a replacement operation for the LED module 300 more simply and conveniently.
