Abstract
PURPOSE: To make the thickness of movement 2.5 mm or under and achieve the extreme reduction in thickness of the watch by making the driving coil of a pulse motor flat and disposing wheel train nearly concentrically to the driving coil.
CONSTITUTION: A battry 33 is disposed on the right side of a plate 1 forming the outside shape of the movement, a circuit substrate 22 on the lower side and a flat coil 16 on the left side, these being in proximity to the outside shape of the plate 1. In order to let the magnetic flux generated by the flat coil 16 be effectively acted on the rotor, an upper yoke 17 and a lower yoke 18 are mounted to the top and bottom of the coil magnetic core and are further fixed by means of screws 34, 35 to both ends of a stator 13. The fourth wheel and pinion 4 intermeshed with the rotor pinion 3b on the upper side than a rotor box 15, third wheel and pinion 5 and center wheel and pinion with cannon-pinion 6 are disposed nearly along the outside circumference of the flat coil and these speed reduction wheel trains position in the central part of the movement.
