2. Description of the Related Art Conventionally, a portable power supply device as disclosed in Japanese Utility Model Application Laid-Open No. 63-153759 has been known. The above-mentioned prior art is a power supply device having a built-in spring (spring) and a small generator, which has a handle, and has a mechanism for manually winding up and a ratchet mechanism for holding a repulsive force of the wound up, The small generator connected by this group and the accelerating gear group with the stop mechanism obtains the generated power by using the repulsive force of the generated beam as the power, and the generated power is converted to the appropriate power by the constant voltage stabilizing device, and the portable power is generated. To be supplied to portable wireless telephones.

[0003]

However, in the above-mentioned prior art, there is a problem that the overall size cannot be reduced because the speed increasing mechanism is interposed between the rotary handle on the outer surface of the case and the rotor of the generator. Was. The purpose of the present invention is to solve the above problems.

[0004]

According to the present invention, in order to achieve the above object, a flat hand-operated generator stator is fixed to an inner surface of one side of a flat box-shaped case, and a rotor is fixed to a shaft of the stator. Rotatably attached to the inner circumference of the rotor
The fixed annular magnet disposed with a predetermined gap therebetween in the annular coil outer periphery of the stator in and fixed to the rotor and coaxially integral with a circular recess formed on the other side of the flat box-shaped casing
Place the rotating body in the recess so as to be flush with the case
An arm is mounted on the outer periphery of the generator so that the arm can be raised and lowered, and a handle is mounted on the end of the arm so that the handle can be raised and lowered. The output of the generator is rectified by a rectifier to charge a built-in battery.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 1 denotes a flat box-shaped case, in which a flat hand-held generator 2 is disposed, a stator 3 is fixed, and a rotor 4 is rotatably mounted on the outer periphery thereof. Reference numeral 5 denotes a rotating body coaxially integral with the rotor 4, which is rotatably fitted into a circular recess 6 formed on one surface of the case 1, and has an arm 8 mounted on a hinge 7 on the outer peripheral portion so as to be able to move up and down. The handle 9 is mounted so that it can be raised and lowered.

When not in use, the rectangular recess 10 on the surface of the rotating body 5
When using, it is 180 around the hinge 7 of the rotating body 5
And the handle 9 is further raised. The case 1 includes a built-in battery 11, a radio 12, and a speaker 13, and a lamp 14 and a charging battery, and a jack insertion hole 15 for connecting an electric device used outside such as an external lamp are mounted on one side.

Next, a circuit diagram will be described. The alternating current from the manual generator 2 is rectified by the rectifier 16 and connected to the jack insertion hole 15 and the changeover switch 18 to the built-in battery 11 via the voltage limiter charging circuit 17. OR circuit 19 from the changeover switch 18 and the built-in battery 11
, And connected to the lamp 14 via the switch 20. The power is directly supplied from the manual generator 2 during power generation, and the power is automatically supplied from the built-in battery 11 when power generation is stopped.

Reference numeral 21 denotes a voltage alarm sensor, which displays a voltage alarm display 22 when the voltage falls below a predetermined value.
Reference numeral 12 denotes a built-in radio which is connected via a switch 23.
Reference numeral 24 denotes a shoulder band attached to the case 1, and reference numeral 25 denotes a radio volume.

Next, the operation will be described. At the time of charging, the arm 8 is raised by 180 °, the handle 9 is further raised, the changeover switch 18 is set to the charging side, the switches 20 and 23 are turned off, and the rotor 4 is turned by the handle 9. An alternating current is generated in the coils of the stator 3 of the manual generator 2. This alternating current is rectified by the rectifier 16, and the built-in battery 11 is charged via the voltage limiter charging circuit 17.

When the lamp 14 is turned on, the switch 20 is turned on. During power generation, the power is turned on by the hand-held generator 2 directly to the lamp 14, and when power generation is stopped, the power is turned on by the built-in battery 11 automatically.

When charging a rechargeable dry battery, the changeover switch 18 is inserted into the jack insertion hole 15 side. The jack of the rechargeable battery holder is inserted into the jack insertion hole 15, and charging is performed while rotating the rotor 4 manually. When listening to the radio, the switch 23 is turned on and the volume is adjusted with the volume 25.

The jack insertion hole 15 can be used to insert jacks of various electric appliances other than rechargeable batteries.
