[0112] figure 1 is a plan view showing an electronically controlled mechanical timepiece according to the present invention, and figure 2 and 3 is its cross-sectional view.
[0113] The electronically controlled mechanical timepiece has a barrel train 1 including a mainspring 1a, a barrel wheel 1b, a barrel arbor 1c, and a barrel case 1d. The mainspring 1a is fixed to the outer end of the barrel wheel 1b and to the inner end of the barrel arbor 1c. The sleeve-shaped barrel arbor 1c has a supporting element fixed thereon, which is provided on the base plate 2 in the shape of a flat disk and is fixed to the square-hole wheel 4 by bending it inwardly with square-hole screws 5 superior. The base plate 2 has a date bridge 2a and a disc-shaped dial 2b fixed thereon. figure 2 and 3 Reference numeral 6 in is the gear train support.
[0114] Therefore, in this embodiment, the mechanical energy is, for example, elastic force generated by the deformation of the mainspring 1a be...

[0140] Refer to attached Figure 5 and 6 A second embodiment of the present invention will be described.
[0141] In the electronically controlled mechanical timepiece in this embodiment, the lengths L1 and L2 of the winding cores 123b and 133b are the same as each other (L1=L2), but the winding wire wound on the winding core 133b is smaller in diameter than that wound on the winding core 133b. The winding of the magnetic core 123b. The number of turns of the respective windings is the same as each other. And the conductivity of a wire with a smaller diameter is greater than that of a wire with a larger diameter.
[0142] This embodiment will bring the following effects.
[0143] (5) Since the windings wound on the winding core 133b are smaller in wire diameter than the windings wound on the winding core 123b, this embodiment with the same number of turns in the coils 124 and 134 can be formed by its smaller wire diameter The volume of the coil 134 is reduced, and the are...

[0145] Refer to attached Figure 7 and 8 A third embodiment of the present invention will be described.
[0146] In the electronically controlled mechanical timepiece in this embodiment, the lengths L1 and L2 of the winding cores 123b and 133b are the same as each other (L1=L2), but the width W2 and thickness H2 of the winding core 133b are smaller than those of the winding core 122b. Width W1 and thickness H1 (W1>W2, H1>H2) and make winding core 133b thinner. And the winding magnetic core 123b is made of PC material, but the winding magnetic core 133b is made of PB material with higher saturation magnetic flux density
[0147] This embodiment will bring the following effects.
[0148] (6) Since the winding magnetic core 133b is thinner than the winding magnetic core 123b, in this embodiment having equal turns and wire diameters in the coils 124 and 134, the coil 134 can be made larger in volume by its smaller wire diameter. becomes smaller and can make the area of the o...
