The plus (+) terminal of the battery B of the battery insertion hole 42 is in elastic contact with the second connection spring 921. Therefore, unlike the above, the second connection spring 921 is pushed backward so that it is not grounded to the ground terminal 94. As a result, the battery B and the second battery insertion hole 42 of the first battery insertion hole 41 are not grounded. The battery B of) is connected in series.

On the other hand, in the case of the front circuit board 60, the positive (+) terminal of the battery B of the first battery insertion hole 41 is grounded with the first terminal portion 61, and the second battery insertion hole 42 The negative terminal (-) of the battery B is in contact with the second connection spring 621 of the second terminal portion 62. At this time, the third connection spring 631 is grounded to the ground terminal 64 by the tension and is connected to the connection terminal portion 65.

As described above, the connection terminal portion 65 and the first terminal portion 61 are connected to the lamp substrate 22 to supply power.

Finally, the case of using nine batteries is described.

As described above, the batteries B are inserted into the first and second battery insertion holes 41 and 42, and the batteries are inserted into the third battery insertion hole 43 so that the negative terminal is visible.

In this case, the rear circuit board 90 is connected to the first terminal portion 91 and the second terminal portion 92 in series, and the third terminal portion 93 is connected to the negative terminal of the battery B while being grounded. The terminal 94 is connected to the connection terminal 95, and is connected to the connection terminal portion 65 of the front circuit board 60.
