The 02 is equipped with detachable levers 103a at both corners on the side opposite to the side where the connector 101 is mounted, in which the extraction arm 103b and the insertion arm 103c are integrated. Desorption lever 1
03a is an electronic circuit package 1 by the rotating shaft 104.
No. 02 is rotatably mounted, and can rotate about a rotating shaft 104.

Next, the electronic circuit package 102 described above.
A method of inserting and removing the back wiring board 100 will be described. First, FIG. 12 shows the electronic circuit package 1.
02 indicates a state of being mounted on the back wiring board 100. In this state, in order to remove the electronic circuit package 102 from the back wiring board 100, first, the attaching / detaching levers 103a on both sides are raised.
Then, the extraction arm 103b contacts the shelf 105. The removal arm 103b is used for the shelf 10
The point where it abuts 5 serves as a fulcrum, and the rotary shaft 104 acts as a point of action, and the detachable lever 103a acts as a force point. Therefore, when the attachment / detachment lever 103a is further raised, the electronic circuit package 102 is removed by the principle of leverage. On the other hand, when inserting the electronic circuit package 102 into the back wiring board 100, the attaching / detaching lever 103a that has been raised in advance is tilted. Then, the insertion arm 1
03c contacts the shelf 105. The position where the insertion arm 103c abuts on the shelf 105 serves as a fulcrum, and the rotation shaft 104 acts as a working point and the detachment lever 103a.
Acts as an emphasis point. Therefore, the removable lever 1
When 03a is tilted down, the electronic circuit package 102 is inserted into the back wiring board 100 by the principle of leverage. The insertion arm 103c also functions as a mechanism for preventing the electronic circuit package 102 from coming off.
