Abstract

A fuel container includes a container body (2) having a fuel discharge port and an interior spacing. A body of liquid fuel is filled in the interior spacing of the container body. Follower units are provided in the container body, in contact with at least a part of an end of the body of the liquid fuel. Solid follower auxiliary members (75 to 78) are interposed between the follower units and the body of liquid fuel to be optically detectable.

Description

technical field [0001] The present invention relates to a fuel container containing liquid fuel, a fuel remaining amount measuring method and apparatus for measuring the liquid fuel remaining amount. Background technique [0002] In recent years, remarkable progress and development have been made in the field of small electronic devices such as mobile phones, notebook personal computers, digital cameras, watches, personal digital assistants (PDAs), and electronic messaging. For power sources in these electronic devices, primary batteries such as alkaline dry batteries and manganese dry batteries, and secondary batteries such as nickel-cadmium secondary batteries and lithium ion batteries are used. However, from the viewpoint of energy utilization efficiency, it cannot be said that effective utilization of energy is generally achieved in primary cells and storage batteries. Today, intensive investigation and research are being conducted on fuel cells capable of achieving hig...
