Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a charger capable of charging a battery to be charged alone or a battery to be charged attached to a device using a battery such as a mobile phone.

[0002]

[Prior art]

 In portable devices such as mobile phones, it is common to use a battery to be charged as a power source. When the charge capacity of the battery to be charged becomes low, the battery to be charged is charged using the charger. At that time, the battery to be charged is attached to the charger and charged while being attached to the portable device, as described in JP-A-3-167768.

On the other hand, in addition to the battery to be charged mounted on the portable device, it is preferable to provide a spare battery to be charged. In this case, the charger is a charged battery mounted on the portable device. It is necessary to be able to charge both the battery and the charged battery for backup. For example, JP-A-1-198232 discloses a charger having two recesses into which a portable device and a battery to be charged are inserted, respectively.

[0004]

[Problems to be solved by the device]

 As described above, a charger having two recesses naturally cannot avoid an increase in size of the charger.

Therefore, an object of the present invention is to provide a small charger that can charge both a battery to be charged mounted in a portable device and a single battery to be charged.

[0006]

[Means for Solving the Problems]

 The present invention is a charger for charging a battery to be charged alone and a battery to be charged attached to a device using a battery, and a common mounting surface on which the battery to be charged alone and the device using the battery can be mounted respectively. A common charging contact electrically connected to each charging terminal of the to-be-charged battery or the battery-using device mounted on the mounting surface.

[0007]

[Action]

 According to the charger of the present invention, both a single battery to be charged and a device using a battery equipped with the battery to be charged can be mounted and charged.
