- the diameter L3 of the fuel injection port 33 is larger than the thickness L1 of the first housing 5 and the thickness L2 of the second housing 6, and the total thickness of the first housing 5 and the second housing 6 It becomes thinner than (L1 + L2). For this reason, even if the fuel inlet 33 is provided in the hinge part 7, it can suppress that the thickness of portable electronic device 1 itself increases.
- the fuel tank 31 and the battery 11 may be disposed at positions that do not overlap in the thickness direction. . Thereby, the weight balance of the portable electronic device 1 which will be in the state of a closed position can be stabilized.
- the sub display 26 is provided on the back side of the first housing 5, but the sub display 26 may be omitted.
- the screw groove 72 provided in the fuel injection port 33 of the portable electronic device 1 and the screw thread 85 provided in the fuel supply port 81 of the fuel cartridge 80 are attached by screwing.
- the screw groove 72 and the screw thread 85 may be eliminated, and the fuel supply port 81 of the fuel cartridge 80 may be pressed against the fuel injection port 33 of the portable electronic device 1 to inject liquid fuel.
- the clamshell type portable electronic device 1 has been described, but other types may be used.
- a revolver type two casings are stacked in the thickness direction, and a hinge portion is provided to connect the two casings so as to rotate relative to each other about a rotation axis along the thickness direction. It may be a dish.
- the portable electronic device according to the present invention is useful in a portable electronic device equipped with a fuel cell, and is particularly suitable for making the portable electronic device thin.
