The one in which the corner portion of the printed circuit board is fitted in the lateral groove is posted.
（考案が解決しようとする問題点） ところが、近時各種電気機器或は電子機器若しくは電気
機器等の小型化につれ、プリント基板Ａ自体にも短小、
小型化が要求され、プリント基板Ａ自体のプリント配線
等も高密化ならざるを得ない。(Problems to be solved by the invention) However, with the recent miniaturization of various electric devices, electronic devices, electric devices, etc., the printed circuit board A itself is short and small.
Miniaturization is required, and the printed wiring of the printed circuit board A itself must be highly dense.
