[0002]

2. Description of the Related Art In recent years, portable telephones have been reduced in size and weight, and communication sensitivity has been dramatically improved. It is likely to come not so far.

A portable telephone uses a secondary battery as a power source,
I always keep my power on to keep my phone waiting for reception. For this reason, the operating time is limited, and one week to 10
It has been charging around the day. Mobile phone charging
Usually, the charging terminal of the mobile phone is connected to a charging terminal dedicated to each mobile phone or a charging terminal of a charging cord connected to a home power supply.

[0004]

According to the conventional portable telephone charging apparatus having such a structure, the structure of the charging terminal and the charging stand is usually different depending on the type of the portable telephone. The device is charging individually. Therefore, if the charging device breaks down or is lost, the charging operation may not be performed because the standard of the charging device of another person does not always match the charging standard of the own mobile phone.

[0005] Also, when charging, it is not always easy to handle such that the charging terminals must be securely connected to each other. In particular, it is troublesome for elderly people to securely connect the charging terminals, and it is not uncommon for the charging operation to be erroneous.

For this reason, a contactless charging device has been proposed in which charging is performed by supplying a charging current by electromagnetic coupling without using a charging contact. However, also in this case, as a structure for supplying the charging current, a concave portion for fitting the mobile phone to the charging base is formed so as to maintain a predetermined positional relationship between the charging base and the mobile phone, and the mobile phone is formed in the concave portion. Are inserted with a predetermined directional relationship, and although the handling is easier than the contact type, the handling is not always easy, and it is still cumbersome for elderly people such as alignment. .

The present invention solves these problems,
It is an object of the present invention to provide a charging device that significantly simplifies a charging operation of a mobile phone and can simultaneously charge several mobile phones at a time.
