Guide and store the pawl,
When the locking claw reaches the locking groove, the locking claw is protruded from the inside of the housing to fix a variety of units.

With this configuration, the locking claw is guided and housed in the housing while the tapered abutment with the locking claw when the various units including the battery pack are slid, so that the locking claw can be operated when the various units are mounted. It can be unnecessary.

Further, the invention according to claim 3 of the present invention provides:
The slide structure according to claim 1 is configured at two or more locations on both inner side surfaces of the housing, and the length of the slide claw and the insertion / extraction groove of each slide structure portion is changed.

With this configuration, when the slide claws of various units including the battery pack are inserted into the insertion / extraction grooves of the mobile phone main body, erroneous insertion into other insertion / extraction grooves is prevented, and the mobile telephone main body and the battery are securely fixed at the fixed position. Various units including packs can be installed.

Further, the invention according to claim 4 of the present invention provides:
A locking claw attached to various units including the battery pack according to claim 2 is integrated with a locking portion and an operation portion, and the operation portion is arranged on a bottom surface of the housing. I have.

With this configuration, it is possible to eliminate the limitation on the length of various units including the battery pack, and to remove various units mounted on the main body of the portable telephone even if various units are added on the various units.

Further, the invention according to claim 5 of the present invention provides:
2. The mobile phone according to claim 1, wherein an insertion / extraction groove, a slide groove, and a temporary fixing groove having the same shape as the main body of the mobile phone are provided on both inner surfaces of the various units, and a locking groove and a taper having the same shape as the main body of the mobile phone. It is characterized by having.

With this configuration, various units can be further mounted on the back of the various units.
