Abstract

PURPOSE:To unify a generator in a cabinet and to supply a power at a arbitrary time by interlocking the generator through plural gears inside the outer periphery of a drum. CONSTITUTION:When an outer circumference knurling tool part 25 of a drum 16 is rotated in being pressed to a flat part, a gear 4a of a generator 4 is speed- increasing-rotated through gears 18a-18c, and the power generated by the generator 4 is charged in a charging battery 5. Consequently, since the power is supplied at the arbitrary time, an external power source can be made unnecessary.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a radio receiver with a generator, which is equipped with a generator that generates charging current to a rechargeable battery built into the radio receiver body.

2. Description of the Related Art In general, electronic devices such as radio receivers use an AC power source or a DC power source as their power source.

In the case of AC power, power is supplied to a radio receiver etc. from a household outlet via a power cord.

In the case of a DC power source, batteries are often used as the power source.

Problems to be Solved by the Invention However, in radio receivers and the like that use such conventional power supply methods, in the case of an AC power supply, power cannot be supplied during a power outage. Further, in the case of a DC power source, when the battery reaches the end of its life, it becomes impossible to supply power and has problems such as being unable to receive emergency broadcasts.

The present invention solves these conventional problems, and aims to provide a radio receiver with a generator that can supply power with a simple configuration.

Means for Solving the Problems The radio receiver with a generator of the present invention includes a generator that generates electric power, a drum that is connected to the generator with a plurality of gears, and a generator that generates electric power. It is constructed with a rechargeable battery that is charged with the generated power.

Operation In the radio receiver with a generator of the present invention, by rotating a drum rotatably disposed on the inner surface of a cabinet, a generator is connected to a plurality of gears meshing with the drum, and the generator generates electricity. The machine generates electricity and generates electricity. The power generated by the generator is charged into a rechargeable battery so that power can be supplied at any time, and there is no need to replace household outlets or batteries, providing a semi-permanent power supply. It has many advantages, such as the ability to

Embodiment Hereinafter, a radio receiver with a generator according to an embodiment of the present invention will be explained with reference to the drawings. 1, 2, 3, 4 and 6 show an embodiment of the present invention. Figure 1 shows the inside of the set with the front cabinet removed. A printed wiring board (hereinafter referred to as a board) 2 is arranged in a substantially parallel manner inside the cabinet 1, and is equipped with a power switch 8 necessary for broadcast reception. Earphone jack9. Components such as a volume 1o, a ferrite antenna 11, a tuning variable capacitor 12, etc. are arranged. Further, as a method of tuning, the tuning knob 13, scale plate 14, and tuning variable capacitor drum 16 are each connected by a gear portion, and by rotating the tuning knob 13, arbitrary tuning is possible. The electric power generated by the generator 4 passes through the generator lead wire 6 and then via the board 2 to the rechargeable battery lead wire 7.
Through this, the rechargeable battery 6 is charged. By turning on the power switch 8, power is supplied from the rechargeable battery 6,
It becomes possible to receive broadcasts. 3 is a chassis made of a metal plate on which the generator 4 and a plurality of gears are stably mounted. FIG. 2 shows a cross-sectional view of the power generation block taken along line A-A in FIG.
It is rotatably held by a drum bearing 22 held by a shaft portion 17 that is attached to the shaft. The drum bearing 22 is sandwiched between the cabinet 1' and the chassis 3, and fixed with decorative screws 2o. The structure is such that a gear 23 formed inside the outer peripheral edge of the drum 16 and a plurality of gears attached to the chassis 3 mesh and interlock. The rechargeable battery 6 is held by a claw 21 formed integrally with the cabinet 1. FIG. 3 is a perspective view showing the structure of the power generation block. A plurality of support shafts 1e are implanted in the chassis 3, and gears 18a, 18b, and 18c are rotatably supported on each support shaft 19. The small gear part of the gear 18& meshes with the gear 23 of the drum 16, the large gear part of the gear 18& meshes with the small gear part of the gear 18b, the large gear part of the gear 18b meshes with the gear 180, and the gear 18Q meshes with the small gear part of the gear 18&. It can mesh with a gear 4N provided on the rotating shaft of the generator 4.

The generator 4 is fixed to the chassis 3 with screws 24, and the through hole 3 of the chassis 3! Generator 4 that got into L
The gear 4& meshes with the gear 18c.

In such a configuration, when the outer peripheral knurling portion 26 of the drum 16 is rotated while being pressed against a flat surface, the gear 4a of the generator 4 is rotated at an increased speed via the gears 18&, 18b, and 180, and the generator 4 generates The rechargeable battery 6 is charged with the generated power.

Effects of the Invention As described above, according to the present invention, the generator is interlocked through a plurality of gears inside the outer periphery of the drum, so that the generator can be installed inside the cabinet of the radio receiver as a small device. It can be configured in one piece. Furthermore, since it does not require an external power source, it is possible to realize a radio receiver with a generator that is easy to use and can receive signals at any time.
