And a spring 223 for urging the pressure type pin 222 upward.

The pressure type pin 222 is urged upward by the spring 223, and the upper end position thereof is restricted by the pin retainer 224. When the system terminal T2 of the movie contacts the pressure type pin 222 from above, the pressure type pin 222 moves down according to the load of the movie 10. In this case, since the spring 223 urges the pressure type pin 222 upward, when the movie is placed at the lowest stable position, the pressure type pin 222 applies a strong force from the spring 223 to the system terminal T2. It is pressed. Also in this manner, a simple mounting method of the movie 10 can be realized by the adapter 1 shown in FIGS.
