Attachment structure of adapter
First Claim
1. An external power supply device to be engageable with an electronic device, comprising:
- a main body which allows a battery serving as a power source to be set in the main body;
a contact support including contacts for supplying power from the battery to the electronic device, the contact support projecting from the main body, and being to be inserted into a battery chamber of the electronic device;
a waterproofing member annularly provided around the contact support to prevent water from entering the battery chamber, the waterproofing member being to be fitted in a concave portion which is provided in the vicinity of a periphery of an opening of the battery chamber, and in which a battery cover is to be set;
a fixing member to be located between the main body and the electronic device, for fixing the main body and the electronic device to each other; and
a first relative position determining member to be provided between the main body and the electronic device, for determining relative positions of the main body and the electronic device,wherein the concave portion and the waterproofing member fitted in the concave portion function as a second relative position determining member for determining relative positions of the main body and the electronic device.
