[Problems to be solved by the device]

 However, the above various conventional structures have the following problems. First, in the structure shown in Fig. 4, the terminals 4 of the battery 3 are fixed to the printed circuit board 1 by soldering, so the battery 3 is collected from the printed circuit board 1 when disassembling and discarding used electronic devices. There is a drawback that the work to do is complicated. To explain this point in more detail, in recent years, it is strongly required to collect used batteries after the necessity of recycling to prevent environmental damage and save resources, and from this point, the structure shown in Fig. 4 is used. Therefore, when removing the battery 3 from the printed circuit board 1, the soldering part where the terminal 4 of the battery 3 is fixed to the printed circuit board 1 must be destroyed, which requires a lot of labor. There is a problem that the work of removing the battery 3 from the substrate 1 becomes complicated.

In addition, the structure shown in FIG. 5 requires a lead wire 6, a connector 7, etc. for electrical connection of the battery 5 to the printed circuit board 1, and in that sense has a drawback that the number of parts increases. .. There is also a problem that it is necessary to study the arrangement and fixing structure of the battery 3 separately from the electrical connection.

Further, in the structure shown in FIGS. 6 and 7, when recovering the battery 9 from the printed circuit board 1, the output pin 8 is pulled out from the pin socket 10 after the fixation of the battery 9 to the battery 9 is released. The work is required, and the labor required for that makes the work of removing the battery 9 from the large number of printed circuit boards 1 complicated, and the same problem as described with respect to the structure shown in FIG. 4 occurs. Also in the structure shown in FIGS. 6 and 7, the pin socket 10, the output pin 8, the box 9a and the strip 12, and the internal wiring of the box 9a are required, and the number of parts is larger than that of the structure shown in FIG. There is a problem.

Therefore, the present invention solves the above-mentioned problems of the prior art, and as a structure for mounting a battery on a printed circuit board, a simple structure with a small number of parts makes it easy to recover the battery from the used printed circuit board. An object of the present invention is to provide a battery holder for a printed circuit board and a printed circuit board on which a battery is mounted by using such a battery holder.
