2. Description of the Related Art Conventionally, portable radio receivers for emergency evacuation as shown in FIGS. 5 and 6 have been known. In the portable radio receiver, a generator, a battery (secondary battery), a radio receiving circuit and the like (all not shown) are provided inside a small portable casing (1), and a casing is provided.
On the surface of (1), a speaker sound emitting section (11), a tuning knob (12), a volume adjusting knob (13), a handle (14) for rotating the generator, and the like are provided.

As shown in FIG. 4, a base end of the handle (14) is a disk rotatably supported on the back of the casing (1).
A pivot (18) is provided at the end of (15), and can swing between two positions, an open position indicated by a solid line and a folded position indicated by a chain line. A knob (16) is rotatably attached to the tip of the handle (14). As shown in FIG. 3, the disk (15) is connected to the rotating shaft of the generator (2) via a gear train (3), and the output end of the generator (2) is connected to the battery (4). ing.

When charging the battery (4), as shown in FIGS. 3 and 4, the handle (14) is opened from the casing (1), the knob (16) is held, and the handle (14) is rotated. . This rotates the disk (15), and this rotation is transmitted to the generator (2) via the gear train (3). The electric power generated by the generator (2) is supplied to the battery (4), and the battery (4) is charged. The electric power charged in the battery (4) is
The signal is supplied to the radio receiving circuit or the like, so that a radio broadcast can be received. After the battery (4) is fully charged, the handle (14) is folded as shown by the chain line in FIG.

In order to charge the battery (4),
The generator (2) needs to generate a voltage within a predetermined range,
To do so, the handle (14) must be rotated at a speed within a certain range. Therefore, conventionally, an LED that is lit only when the power generator (2) is generating the voltage in the predetermined range is provided on the surface of the casing (1) (not shown), and LE
By confirming the lighting of D, the steering wheel (14) can be rotated at a speed within the above-mentioned fixed range.

[0006]

However, in the conventional portable radio receiver, the operation of rotating the handle (14) while confirming the lighting of the LED is extremely tedious and tedious. Therefore, an object of the present invention is to relieve the boring of the operation of charging a battery in a rechargeable electric device that charges a battery (4) by rotating a generator (2) by rotating a handle (14). That is.

[0007]

In a rechargeable electric device according to the present invention, a handle (14) is provided inside a casing (1).
A first rotation transmission mechanism for transmitting the rotation of the steering wheel to the generator (2), a sounding mechanism for playing music by receiving the rotating power, and a second rotation transmission mechanism for transmitting the rotation of the handle (14) to the sounding mechanism. A gear is provided by the first rotation transmission mechanism so that the generator (2) generates a required charging voltage according to the rotation speed of the handle (14) when the sounding mechanism plays music at a normal pitch. The ratio and the gear ratio by the second rotation transmission mechanism are adjusted. Here, a music box mechanism (5) can be adopted as the sounding mechanism. Further, a gear mechanism can be adopted as each of the first rotation transmission mechanism and the second rotation transmission mechanism.

[0008] In the rechargeable electric device of the present invention,
By rotating the handle (14), the rotation is
At the same time as being transmitted to the generator (2) via the rotation transmission mechanism,
The sound is transmitted to the sounding mechanism via the second rotation transmission mechanism, whereby the sounding mechanism plays music. Here, if the rotation speed of the handle (14) is within the proper range, the sounding mechanism plays music at a normal pitch, but if the rotation speed of the handle (14) is out of the proper range, the sound is produced by the sounding mechanism. Music has abnormal pitches. Therefore, the rotation speed of the steering wheel (14) is adjusted so that the sounding mechanism plays music at a normal pitch. As a result, the power generator (2) generates a voltage in a predetermined range capable of charging the battery (4).

[0009]

According to the rechargeable electric device according to the present invention,
Since the handle can be rotated while enjoying the music played by the sounding mechanism, the boring of the charging operation is greatly reduced.
