摘要： PROBLEM TO BE SOLVED: To eliminate the deficiency that amorphous silicon adopted as photovoltaic power generation members of solar cells can have been used only for a wrist watch having a circular or large radial outer circumferential shape since crack destruction occurs in amorphous silicon when it is bent with a small radius. SOLUTION: In this electronic timepiece 20 with solar cells, a plurality of band-like solar cells 1 are independently arranged approximately perpendicularly to a dial 2 along a plurality of sides 2a-2d forming a principal outer circumferential shape. Since the solar cells 1 comprising photovoltaic power generation parts constituted of very friable material are arranged at corner parts 2e-2h of the dial 2 in this way, there is no need for bending and using the band-like solar cells 1 with a small radius, and it is possible to provide the dial with a free shape such as a rectangular shape, a barrel shape, or the like.

摘要： PROBLEM TO BE SOLVED: To solve design-restriction problems in a conventional electronic clock with a solar cell having the solar cell arranged substantially vertically to a dial plate and stored in a supporting ring groove part and requiring a depth for obtaining a necessary power generation amount because a supporting ring connection part is positioned on the wind shield side or an electronic clock having a solar cell arranged in a parting diameter part in a stainless steel thin plate and cannot shield a dark brown color of the exposed solar cell. SOLUTION: A flexible solar cell 1 is optically stuck to the outer circumference of a translucent lining ring 2 arranged in a clearance between wind shield glass 4 and the dial plate 5. Alternatively, the solar cell 1 is arranged to be optically stuck to a supporting ring 22 having a groove part 10a on the wind shield side of the lining ring 2. In this way, a structure capable of securing a sufficient power generation amount and solving designing problems can be realized. COPYRIGHT: (C)2003,JPO

摘要： PROBLEM TO BE SOLVED: To solve the problems wherein, concerning a flexible solar cell arranged approximately vertical to a dial on the circumferential part of a movement of an electronic timepiece in order to supply a power to the electronic timepiece, in the case where patterning is a one-stage light power generation cell, a booster circuit for boost is required, though a merit exists wherein a power generation voltage is hardly changed to partial shielding caused by clothes or the like, and in the case of a light power generation cell with a plurality of stages of a rectangular pattern, output fluctuation caused by the partial shielding is large or a series/parallel switching switch circuit is required to thereby increase the complexity and a space of circuit or a power consumption, though the booster circuit is not required because the power generation voltage is acquired highly. SOLUTION: This electronic timepiece is constituted so that the light power generation cells are arranged alternately in a comb-shaped state, and thereby a light receiving range in each stage is widened and a stable power can be supplied to a secondary cell.

摘要： PROBLEM TO BE SOLVED: To solve the problems on design restrictions that, when a solar cell is arranged at a dial rim part of the outer periphery of a dial plate, a clearance between a wind shield glass and the dial plate becomes widened so that the position of the dial is recessed, and that, when the cell is arranged at a parting diameter part, the cell is exposed so that the dark blown color of the cell becomes revealed. SOLUTION: A light-permeable lining ring is arranged inside a solar cell, and a part of a solar cell power generating area and a part of the lining ring covering the solar cell power generating region are disposed below the level of the upper face of a dial. Further, the thickness of the dial plate on its internal side is made larger than that of the dial at its peripheral part on which the translucent lining ring is disposed while a light guid part for incident light on the lining ring is retained. Or, a flange part for fixing a wind shield glass to a timepiece case is arranged outside the translucent lining ring and the solar cell, the lining ring is disposed immediately beneath the wind shield glass and a blinder part is provided at the upper part of the lining ring or solar cell.

摘要： PURPOSE:To enforcedly rotate a step motor and produce no dislocation of a time even if power is generated by providing a means for measuring a power generation time, a means for stopping said step motor and a means for rotating said step motor faster than a normal operation to compensate the power genera tion. CONSTITUTION:At the time of normal drive a signal from a drive circuit 13 is received to drive a hand indication 5 through reduction wheel trains 4 includ ing a slip mechanism 10 and a reverse rotation prevention mechanism 11 so as to show a normal time. When the timekeeper is charged with a power source an outside operation member 1 is operated, and speed increase wheel trains 2 including an one-directional clutch 8 and a switch 9 are rotated to rotate a step motor 3 at high speed so as to charge it with a power source 6 through a charge circuit 12. At this time, the drive circuit 13 stops the generation of a drive signal by the action of a control circuit 7 and further at the same time a power generation actuation time is measured. Still further, when charge is completed, the rapid traverse of the step motor 3 is performed through the drive circuit 13 by the action of the control circuit 7 so as to allow the hand indication 5 to coincide with a present time.

摘要： PURPOSE:To prevent a gap from being formed between a dial and a case panel cover and a module from having a play at the time of hand correction by correcting or inputting hands by the rotation of a rotary bezel. CONSTITUTION:The rotary bezel 3 is pressed in to engage an internal gear 13 with a hand correcting wheel 14 and rotated in this state, so that the internal gear 13 rotates the hand correcting wheel 14 according to the rotation of the bezel. Further, the rotation is transmitted to a timer hand gear 24b through a switch gear 25a and a timer hand 2a mounted on a timer hand shaft 24 is moved. When the rotary bezel 3 is freed from the hand, the internal gear 13 and hand correcting wheel 14 leave each other with the repulsive force of a spring 10 and from the moment, no load is placed on the hand correcting wheel 14 from the internal gear 13 of the rotary bezel 3, so that a timer starts.
