[Effect of device]

 As described above, according to the present invention, in order to take out the mounting body housed in the housing space of the electronic device body, the insertion member may be inserted into the insertion groove, and the insertion member may be a coin or the like. It is very convenient because it is good. Since it can be taken out in this way, the mounting structure of the mounting body to the main body of the electronic device does not have to be complicated, and the number of parts can be reduced so that cost can be reduced and quality reliability can be improved. be able to. In addition, it is possible to reduce the waste of the storage space and reduce the size of the product.

As described above, according to the present invention, since the retaining pieces formed on the mounting body are fitted into the retaining holes formed on the body of the electronic device, the connectors are attached to all the openings. Also in this case, since the mounting body is fixed to the main body, the cover body and the main body are not separated from each other, and thus the mounting body can be prevented from being lost.

Further, since the mounting body is configured to have a size that fits into the recess formed by recessing from the one surface of the main body, the area can be small and the cost of the material can be reduced.

Further, since the surface of the mounting body that faces the outside in the state of being mounted on the main body is substantially flush with one surface of the main body, it is possible to improve the aesthetic appearance in terms of design.

Further, according to the present invention as described above, since only one end of the compression spring is fixed, the compression spring is automatically rotated by the spring force after the mounting body is angularly displaced with respect to the electronic device body. It can be angularly displaced to a larger angle without being affected by the spring force of.

Further, since the distance between both ends of the compression spring in the circumferential direction can be adjusted, the range in which the spring force is applied can be changed.
