In the first and second embodiments, the power input terminal 1 is located on the front side of the rotating shaft 7b of the rotating member 7.
Although the power supply pin 1 and the power supply pin 10 are provided, a structure in which a power supply input terminal and a power supply pin are provided on the back side of the rotating shaft 7b may be adopted. In this case, when the lid is held on the back surface of the main body, the power supply pin comes into contact with the power supply terminal through an opening formed in the rotating member.

[0042]

According to the present invention, a stable connection between the power supply terminal provided on the external power supply device and the power supply input terminal provided on the lower surface of the main body is always established regardless of the turning operation of the lid. Can be secured. That is, whether the electronic device is in the used state or the unused state, it is possible to always receive continuous power supply from the external power supply device.

Further, power supply is automatically performed simply by mounting the electronic device on the external power supply, and execution of a predetermined operation can be started without an instruction from the operator.

As described above, a stable power connection to the stand-type external power supply can be always ensured irrespective of the open / closed state of the lid, and the power supply is secured by being mounted on the stand. Accordingly, the execution of the predetermined operation can be automatically started.
