とろうとする本発明と、目的が根本的に異なっている。In addition, the transmission gear train becomes a speed-increasing gear train starting from the external operating member 1, and the mainspring 11 can be deformed a lot with a small movement of the external operating member 1. , it is possible to set it to wind up. Therefore, when you rotate your finger on the external operating member 1 and return it to its original position, even though the external operating member 1 is not rotating,
The rotor 15 is connected to the mainspring 1. It is possible to keep rotating it continuously with the force of I, and as shown in the generated current waveform diagram in FIG. 2, it is possible to keep generating electricity at all times. In this case rotor 1
The total rotational speed of No. 5 is almost the same as that of the conventional structure, but the rotor rotational speed is faster and the frequency is higher in the conventional example. However, in the case of a generator using a coil, when the frequency increases to a certain extent, due to the relationship with the rust conductance,
There is a well-known phenomenon in which the generated current gradually saturates, and the effect of increasing the frequency of rotor rotation fades. On the other hand, there is a well-known phenomenon of charge 1-1 current x time, and as time increases, power generation f increases. In view of this, the uninvented embodiment suppresses the decrease in power generation tt due to the lowering of the frequency, makes it possible to increase the power generation room by increasing the power generation time, eliminates or reduces the conventional power generation invalid time, and improves the conventional power generation time. Compared to this, manual winding time can be significantly shortened. There is an example of a patent using a car with a spring in the middle of the transmission path, such as JP-A-55-42775, but in this case, it is used as an energy storage car, and after storing a certain amount of load, the control mechanism The idea is to release a large amount of energy to the rotor or piezoelectric element.By averaging the energy, the rotational frequency of the rotor will be lower, but if the power is being generated for a longer time. The purpose of this invention is fundamentally different from that of the present invention.

る。In the above embodiments, the structure of the mainspring wheel is not limited to this, and the load from the external operating member is transferred to the mainspring''ff:
Any structure may be used as long as it transmits the signal to the next transmission vehicle via the transmission line. Furthermore, the number of spring wheels is not limited to one, and two or more may be used to reduce the size of the spring wheel. or,
The transmission speed increasing ratio and the spring force of the mainspring can be selected to be the most efficient according to the performance of the generator.

る。As described above, according to the present invention, by using a wheel with a mainspring in the transmission path that generates power by hand-winding, the external operating member can be rotated with a finger and returned to its original position. It is possible to provide an electronic watch that can generate electricity effectively even during leisure time, significantly shorten the time required for charging, and that can be easily wound by hand. Also, if it is only for hand winding,
It is possible to eliminate the rotary weight, which is the biggest cause of thickening of the movement and cause it to warp, making it possible to make the movement thinner.
