る。The conventional fire receiver constructed as described above has the following problems. (1) Since many stud bolts 105 are attached to the back surface of the front plate 102 of the door 101 by spot welding,
The surface plate 102 is distorted and the surface of the surface plate 102 is unmarked because of welding marks. (2) A component or tool may hit the stud bolt 105 during the assembly work to damage the component or the like, and the stud bolt 105 may bend, which makes repairing troublesome. (3) Shine trim 1 on the edge of the window 103 of the door 101
04 is attached, and the window frame 119 is attached to the display window 118 of the display plate 117. Further, the operation portion and the display portion are inserted into the stud bolts 105 and fixed with nuts or screws. Since the above parts are required and many man-hours are required for assembling, the cost is increased.

いた。(4) The shine trim 104 is attached to the edge of the window hole 103 of the door 101 to form the window frame. However, aligning the four corners of the shine trim 104 at right angles is troublesome and requires a lot of time. Not only that, but also the central portion of the shine trim 104 attached above and below the window hole 103 may be bent and spoil the appearance. (5) For example, 20 display windows 118 are provided on the display board 117 to display a fire in 20 districts. However, recently, one fire receiver is used to display an extremely large number of districts (for example, 40 districts). It is now possible to receive fires in ~ 80 districts. Therefore, as the number of display windows 118 increases, a display unit corresponding to each increase in the number of display windows 118 must be manufactured, which is not only extremely troublesome but also costly.

There is. Board products such as the fire detection device according to the present invention,
A side wall having a stepped open edge is formed by squeezing on the door attached to the outer box, and one open edge has a first hooking claw and the other open edge has a second hooking claw. The folding plate provided on each of the projecting plate and the operation plate having an engaging hole through which the first hooking claw is inserted and the engaging plate through which the second hooking claw is inserted is provided with a step. It is integrated by being held and joined, and these are engaged with the first and second hooking claws and attached to the open edge of the door by the stoppers.

れていない。According to the board product having the above structure, the problem of the Shine trim and the stud bolt is that the side wall is provided at the edge of the opening of the door and the hook is provided to engage the display plate and the operation plate. Although it was solved by engaging the holes, since the display plate and the operation plate are installed inward from the surface of the door by the width of the side wall, the door and therefore the entire product become thicker accordingly.
We cannot meet the demand for thinner products. Further, there is a problem that a gap is apt to be formed between the side wall provided at the opening of the door and the display plate and the operation plate attached to the side wall, and dust and the like enter the main body through the gap. Furthermore, as described above, when the number of reception areas increases, the display unit must be manufactured correspondingly, and this problem has not been solved yet.
