あった。2. Description of the Related Art As a conventional printed circuit board technology according to the present invention, as shown in FIG. 3, a position where a fuse 1 can be easily attached and detached even when the printed circuit board is incorporated in a power supply plate. The fuse 1 is arranged in the above. This may result in an inefficient design such as an increase in the area of the printed circuit board as a result of an unreasonable pattern design by giving priority to the arrangement of the fuse 1. In addition, when efficient component placement and pattern design are performed,
As shown in FIG. 3, the fuse 1 may be disposed inside the power supply plate and may be surrounded by other components. Here, the usual removal of the fuse 1 has been realized by pulling it out from the direction A. Therefore, it is difficult to attach and detach the fuse 1 unless the entire printed board 4 is pulled out from the power board.

ていた。In the prior art disclosed in Japanese Utility Model Laid-Open No. Sho 62-184773, there is a conventional example in which a hole is formed in a printed circuit board directly below a component for the purpose of facilitating the removal of surface mount components. In the printed circuit board without holes, the glass tube current fuse is looked into from the component mounting surface.
It was provided in front of the printed circuit board. That is, it was confirmed whether or not the current fuse was broken only from the component side.

必要となるといった課題があった。As described above, in the prior art, in order to optimize the arrangement of the fuses, it is a problem that other component arrangements are sacrificed or the pattern design becomes inefficient. . In addition, as shown in FIG.
When the fuse 1 is surrounded by other components and is arranged in the back of the power supply plate, there is a problem that the fuse 1 is not blown and the fuse cannot be easily replaced. Further, in a structure in which the solder side of the printed circuit board is mounted on the front side during service, there is a problem that it is necessary to remove the printed circuit board and turn it over.

が可能となるものである。In FIG. 1A, a glass tube current fuse 1 is mechanically held and electrically connected to a printed circuit board 4 through a fuse holder 3. The fuse holder 3 is soldered to the pattern on the printed board 4 after being inserted into the printed board 4. Here, the printed circuit board 4 is provided with a hole 2 at a position located below the glass tube current fuse 1. As shown in FIG.
It is the figure seen from the back surface (soldering surface) of the printed circuit board 4. As is apparent from the figure, the glass tube current fuse 1 can be directly viewed from the back surface of the printed board 4 through the hole 2.
