基板にハンダ付けするようにしていた。2. Description of the Related Art In electronic devices such as video tape recorders (VTRs), light emitting display elements such as LEDs are often used in display panels and the like. In these electronic devices, the exterior panel and the printed circuit board are often arranged not in parallel but perpendicularly, but in this case, the light emitting display element disposed on the printed circuit board is placed on the exterior panel. In order to illuminate the display at a position close to the display, a light emitting display element whose lead legs are bent at right angles is soldered to a printed circuit board.

角に折り曲げられる。FIGS. 6 and 7 are diagrams showing such a conventional configuration, in which a light emitting display element 1 such as an LED having a light emitting part 1a and two lead legs 1b is mounted on a printed circuit board 2. As shown in FIG. 6, the lead leg 1b is bent in advance at a substantially right angle at a predetermined position.

うになっている。As shown in FIG. 7, for example, a holder 10 is attached to the printed circuit board 2 by snap-in fitting or the like.
The light emitting display element l is supported by its lead leg 1b.
The lower end of the printed circuit board 2 was connected and fixed to a predetermined conductor pattern by solder 3. In FIG. 7, reference numeral 4 denotes an exterior panel, and 4a denotes a display window thereof, with the light-emitting section 1a of one light-emitting display element 1 facing the exterior panel.
ところで、上述した従来の発光表示素子１の取付け構造
では、発光表示素子１のリード足１ｂを、オートデイツ
プハンダ付けによる手法でプリント回路基板２に接続し
にくいという問題があった。By the way, the above-described conventional mounting structure for the light emitting display element 1 has a problem in that it is difficult to connect the lead legs 1b of the light emitting display element 1 to the printed circuit board 2 by auto dip soldering.

、発光部１ａがプリント回路基、板２の端部に近すぎる
ため、オートデイツプ時のフラックスで発光部１ａが汚
れてしまい、暗くなってしまうという問題もあった。This is because when the printed circuit board 2 and the exterior panel 4 are disposed orthogonally as described above, the display window portion 4 of the exterior panel 4
The light-emitting display element 1 for illuminating the light-emitting display element 1 will necessarily be positioned at the end of the printed circuit board 2, and furthermore, the light-emitting part 1a of the light-emitting display element 1 will be located outside of the lead leg 1b. This is because it often gets in the way of the hanger for auto-dip soldering. Furthermore, since the light emitting section 1a is too close to the end of the printed circuit board 2, there is a problem that the light emitting section 1a becomes dirty with flux during auto-dipping, resulting in darkness.

必要がある場合にも。The present invention has been made in view of the above points, and its object is that an exterior panel and a printed circuit board are arranged perpendicularly, and a light-emitting display element is provided with lead legs near an edge of the printed circuit board. Also when it needs to be placed in a state bent at a nearly right angle.

となる。The first stepped portion of the holder places and supports the light emitting part of the light emitting display element with the lead legs standing upright, and the lead legs are auto-dipped soldered in this state. Therefore, during the soldering process, the light-emitting display element can be kept relatively far from the edge of the printed circuit board, so it does not get in the way of the hanger for auto-dipping, and the light-emitting part is not contaminated by flux during auto-dipping. There is no longer any risk of being caught. Further, after soldering, the upright lead leg is easily bent, for example, at a substantially right angle, using the corner portion of the second step provided at a predetermined height position as a bending point, and the light emitting portion is folded into the printed circuit. It will be positioned on the edge side of the board.
