Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a charging device for a portable electronic device such as a portable information terminal typified by a portable telephone, and more particularly, to a method for holding a charger by placing the portable electronic device horizontally. In addition, the charging terminal of the portable electronic device is surely brought into conductive contact with the electrode terminal of the charger.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 6, a charger for a portable electronic device, for example, a portable telephone has been widely applied.

The mobile phone 40 is of a system in which the lower end is vertically inserted into a concave portion 42 of a charger 41 for charging. That is, in a state where the charging terminal provided on the lower end surface of the telephone main body is brought into conductive contact with the electrode terminal arranged on the bottom of the concave portion of the charger 41, the cellular phone 40 and the mobile phone are made uneven. It is configured to be mechanically held by engaging means such as a part.

[0004]

By the way, in the case of the above-described vertical charging system, the mobile phone being charged becomes unstable, and the telephone body and the charger are held by the engaging means. Even in the state, since the charging terminal of the mobile phone 40 and the electrode terminal of the charger 41 are in a conductive state due to only the contact pressure, if the mobile phone is inadvertently moved during charging, the contact state between the two terminals is changed. There is a problem that it easily comes off.

On the other hand, when the mobile phone is set to the horizontal charging method, the stability is good. However, since only the lateral pressure is applied to the mobile phone and the charging terminal is pressed against the electrode terminal of the charger with a predetermined contact pressure. However, it was not clear whether or not both terminals were surely brought into conductive contact when the mobile phone was attached to the charger. In addition, in this case, if the mobile phone is inadvertently moved while being charged, the contact state between the two terminals is likely to be released, and the reliability cannot be said to be high.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and enables a charging terminal to surely make conductive contact with an electrode terminal without mounting errors, thereby stably maintaining a charged state. An object is to obtain a charging device for a portable electronic device.

[0007]

In order to achieve the above-mentioned object, a portable electronic device charging apparatus according to the present invention is a system in which a portable electronic device is mounted horizontally on a charger and a charging operation is performed. The portable electronic device near the charging terminal is provided with a hooking means to be engaged with the charger.

[0008] With this configuration, the portable electronic device is placed on the mounting surface of the charger in a state where the portable electronic device is engaged with the charger by using the hooking means. The terminal can be reliably brought into conductive contact with the electrode terminal of the charger, and the contact state of both terminals does not come off after the portable electronic device is mounted.
