2. Description of the Related Art In a charging device used for charging a battery of a mobile communication device such as a mobile phone or a PHS, the mobile communication device is connected to a personal computer or the like with a connection cable while charging, as well as charging in a normal standby posture. There are chargers that can communicate. (Japanese Patent Laid-Open No. 20
FIG. 8 illustrates a conventional example. In a conventional example, when a battery of a mobile phone is charged by a concave charging device main body 30 having a built-in power plug 31 that can be stored in the charging device main body, the charging device main body is folded when the charging device is carried and not used. A cradle 32 of a mobile phone which is stored in a cradle storage portion 35 provided in the cradle 30 and is mounted so as to be movable.
And put the mobile phone 36 on it. This cradle 32
Has a spring-like engaging portion (not shown) that engages with the main body of the charging device to fix the cradle. When a mobile phone is placed on the cradle, the charging device main body 30
The charging terminal 34 having a spring property provided on the mobile phone 36 and the charging terminal contact portion 37 on the side of the mobile phone 36 are brought into pressure contact with each other to be able to conduct electricity. Further, the receiving table 32 has a function of regulating the floating of the mobile phone 36 due to the press-contact of the charging terminal 34 having the spring property and the charging terminal contact portion 37, thereby ensuring stable power supply. Furthermore, a method has been proposed in which data communication is performed by connecting a plug 38 of a connection cable to a connection connector 39 built in the mobile phone 36 through an opening 33 provided in the receiving stand 32.

[0003]

In the prior art, when charging the battery of a mobile phone on a desk, first, the cradle of the mobile phone built and stored in the charging device body is pulled out and fixed, and the mobile phone is fixed. Place the phone on its side, place it on its side, and with the power plug stored in the charging device body, use an extension cable or the like from the power outlet on the wall side, and plug the outlet of the extension cable into the power plug. Supply power. In this case, there is a problem that the mobile phone is completely laid horizontally and the antenna is also laid sideways, so that the transmission / reception sensitivity is deteriorated. When charging by plugging the power plug up and plugging directly into the wall outlet, the antenna of the mobile phone will be upright, so the receiving and transmitting sensitivity will be improved.However, the wall outlet is usually close to the floor, so The mobile phone is bent and operated, and the usability of charging and data communication of the mobile phone is very poor. Further, since the mobile phone is close to the floor, the receiving and transmitting sensitivity cannot be said to be good.

In order to perform the above-described series of operations such as charging and data communication, it is necessary to insert and remove a power plug from a charging device main body, insert and remove a cradle of a mobile phone, and fix and release the cradle. In addition, when performing data communication, the operation is complicated and difficult, for example, it is necessary to pass the connection plug of the data communication cable through the opening of the cradle from the bottom side and connect it to the connection connector of the mobile phone .

[0005] Further, since the cradle of the mobile phone, which is rotatably incorporated in the main body of the charging device, is a resin product integrally formed with a fixing resin spring which engages with the main body of the charging device, the mobile phone is somewhat excessive. When pressed from above the pedestal, the oscillating shaft and the resin spring portion may be damaged, or the pedestal itself may be damaged, and there is a problem in strength. In addition, in this conventional example, the number of parts such as a reciprocating cradle increases, so that the cost also increases.

[0006]

SUMMARY OF THE INVENTION According to the present invention, in a charging device for a portable communication device, charging and data communication can be simultaneously performed easily without a complicated procedure operation, as well as a normal charging in a table-top posture. Provided is a charging device that is excellent in operability, simple in structure, and excellent in reliability.
