[0044] First, refer to Figure 1 to Figure 9 The first embodiment in which the present invention is applied to an analog double-hand electronic clock is described.
[0045] figure 1 It is a sectional view of the driving part of the analog two-hand electronic clock, the basic driving force transmission mechanism and Figure 19 The previous example shown has the same gear set construction, so it is the same as the Figure 19 Corresponding parts are denoted by the same symbol.
[0046] exist figure 1 Among them, 1 is a stepping motor, which is composed of a rotor 1a, a stator 1b, and a coil 1c. When it is driven, the rotor 1a rotates intermittently at 180° per second. The rotation of the rotor 1 a is transmitted to the fifth gear 3 coupled to the rotor pinion (pinion) 2 , and the fourth gear 5 is rotated by the fifth pinion 4 rotating integrally with the fifth gear 3 . The rotation of the fourth gear 5 is transmitted to the third gear 7 through the fourth pinion 6 which rota...

[0087] Below, refer to Figure 10 ~ Figure 18 A second embodiment in which the present invention is applied to an analog three-hand electronic clock will be described.
[0088] Figure 10 is a cross-sectional view of the driving part of the analog three-hand electronic clock, and figure 1 The same parts are denoted by the same symbols.
[0089] exist Figure 10 Among them, when the rotor 1a of the stepping motor 1 rotates 180° per second intermittently, the rotation of the rotor 1a is transmitted to the fifth gear 3 combined with the rotor pinion 2, and the fifth small gear 3 integrally rotates with the fifth gear 3 Gear 4 rotates the fourth gear 5 .
[0090] The fourth gear 5 rotates integrally with the fourth pinion 6 and the fourth shaft 25 to rotate the second hand 19 attached to the tip of the fourth shaft.
[0091] Moreover, the rotation of the fourth shaft 25 is transmitted to the third gear 7 through the fourth pinion 6, and further transmitted to the second gear...
