are disposed surrounding the coil frame 1 and in contact with both ends of the iron core 2. Also, the iron core 2 has a shaft 5.
A pinion 7, which is integrated with a magnet rotor 6 and faces the stator plate 4, is pivotally supported on the shaft 5 via a bearing 8.
The pinion 7 will be linked to the clock wheel train E. FIGS. 4A to 4C show the step motor D.
is shown assembled into a printed circuit board P, and as shown, the printed circuit board P is provided with a substantially U-shaped notch 9, and the stator plate 4 of the step motor D is provided with the notch 9. A notch 10 is provided so as to engage the edge of.

回転角に変換する。 Therefore, as shown in Figure A, the step motor D
By inserting the step motor D into the notch 9 of the printed circuit board P from the direction of arrow X, the step motor D can be reliably fixed by protruding from both the front and back of the printed circuit board P. In the figure, 11 is a crystal resonator, 12 is a capacitor, 13 is a trimmer capacitor, 14 is an IC 15 is a pulse generation capacitor,
Reference numeral 16 denotes a driving force transmission unit that links the pinion 7 and the clock wheel train E. In reality, most of the crystal oscillation circuit A, frequency dividing circuit B, and motor drive circuit C shown in Fig. 2 are as shown in Fig. 5. It is incorporated into the IC 14, and the lead wires to the coil 3 of the step motor D are printed and wired. Further, in detail, the circuit configuration of FIG. 5 includes the crystal resonator 11, capacitor 12, trimmer capacitor 13, and
A crystal oscillation circuit A is configured by an amplifier built in 4, and the output of the crystal oscillation circuit A is transmitted to the IC.
14 to obtain a desired frequency divided output. Next, the output of the frequency divider B is applied to the coil 3 of the step motor D via the pulse generation capacitor 15, and the number of generated pulses is converted into the rotation angle of the shaft 5.
