bscriber identity module) Various functions are expanded and the user is specified by attaching an IC card such as a card, a memory card, or a smart media (trademark).

In such an electronic device, the following structure has conventionally been adopted as a connector structure for holding an IC card.

[0004] For example, Japanese Patent Application Laid-Open No. Hei 9-185973 discloses a socket connector structure of an IC card for a portable telephone.

In this prior art, a plurality of metallic elastic contacts are protruded from a base made of an insulator, and a lid is rotatably connected around one end of the base. An accommodation groove into which the SIM card is inserted is formed on the back surface side of the lid, and the SIM card is held with its circuit portion exposed with its surface facing the base side exposed. Therefore, after inserting the SIM card into the accommodation groove,
By returning the lid to the closed position, the circuit portion of the SIM card makes elastic contact with the contact. A lock mechanism for locking and fixing the both is provided between the base and the lid.

Such a socket connector structure comprising a base and a lid is accommodated in a concave portion formed on the back surface of the housing of the main body of the portable telephone or the mounting surface of the main body of the portable telephone on which the battery pack is mounted. Accordingly, the recess in which the socket connector structure is accommodated is covered.

As described above, in the prior art, the IC card is held by the socket connector structure including the base and the lid in the recess formed in the housing of the electronic device. There is a problem that a connector having a complicated structure must be adopted, the number of parts is increased, and the cost of the device is increased. Further, there is a problem that a large occupied volume is required.
In addition, this conventional technique requires a cover for covering the connector housed in the recess.

There has been a demand for electronic devices such as mobile phones of this type to be light and thin and compact, and a holding mechanism for holding an IC card with a configuration as simple as possible has been demanded.

The present invention has been made in view of such circumstances, and an electronic device capable of holding an IC card with a very simple and space-saving structure, realizing a reduction in the number of parts and a reduction in cost. An object of the present invention is to provide an IC card mounting structure and a battery pack.

According to a first aspect of the present invention, an electronic device main body forms a part of a housing of the electronic device when the electronic device main body is mounted and is mounted on the electronic device main body by a predetermined locking mechanism. An electronic device comprising: a detachable battery pack that is held and fixed; a backside of the battery pack, a holding member that detachably holds an IC card, and the battery pack is attached to the electronic device body. Sometimes, a contact that comes into contact with an external electric contact of the IC card is provided on the electronic device main body side.

According to a second aspect of the present invention, there is provided a detachable battery pack which forms a part of a housing of an electronic device when mounted, and is held and fixed to the electronic device body by a predetermined locking mechanism. When the battery pack is mounted on the electronic device main body, the IC card can be detached so that the external electric contact of the IC card comes into contact with the contact provided on the battery pack mounting surface of the electronic device main body. It is characterized in that a holding member for holding is provided on the back side of the battery pack.
