Abstract: A battery electrode terminal member has a spring plate structure comprised of a base body part configured to be mounted to and supported by a casing of a timepiece main body in substantial perpendicular relation to a main face of the timepiece main body. A battery electrode contact terminal part of the spring plate structure extends from one end of the base body part for elastical pressure contact with a peripheral face part of an electrode of a battery.

Abstract: To provide a reset current conductive path between a reset lever and an overhang of a printed circuit board without using a conductive part such as a metal pin and without bending a distal end portion of the reset lever. When a movement is assembled, an overhang pattern is accommodated in an embracing recessed portion which is formed in a plate, is bent to a height of a reset lever, and a distal end portion of the overhang pattern reaches a recessed portion which is dug downwardly from a reset lever planar moving surface. Then, such a bent state of the overhang pattern is held by arm portions of the embracing recessed portion. Accordingly, when a winding stem is pulled by one stage, the reset lever performs the planar movement in the given direction and a distal end portion of the reset lever is brought into contact with the overhang pattern.

Abstract: To provide a ball bearing device with less possibility that its stable operation is disturbed, an oscillating weight structure for automatic winding and an automatic winding timepiece equipped with the ball bearing device. A ball bearing device 1 suitable for use in an oscillating weight structure for automatic winding timepiece includes an outer ring, an inner ring, a plurality of balls disposed between the outer ring and the inner ring regulated in the radial direction, a retainer provided with a plurality of recessed sections in the circumferential direction at intervals each having an opening in the outer periphery for holding respective one of the balls in the circumferential direction at intervals, and rotatably fitted to the inner ring.

Abstract: To provide a battery electrode terminal member capable of suppressing an occupation area along a main face of a timepiece main body to a size of lowest limit, and an electronic timepiece possessing the same. A battery electrode terminal member of an electronic timepiece comprises an elongated metal-made plate spring as a whole, and has a base body part mounted to and supported by a machine casing of a timepiece main body substantially, perpendicularly to a main face of the timepiece main body, and a battery electrode contact terminal part extended from one end of the base body part 51 and elastically pushed to a peripheral face part of an electrode of a battery. The base body part is held while being nipped between protrusion parts or in groove parts of the machine casing of the timepiece main body.

Abstract: An electronic timepiece adapted to minimize a horizontal slippage of contact terminals when a display unit housing is diagonally fitted in a case. A liquid crystal panel, and an electroluminescence panel adapted to illuminate and secured to a rear surface of the liquid crystal panel are provided. A display unit housing retains the liquid crystal panel and electroluminescence panel. The display unit housing has guide holes for inserting electric terminals thereinto and holding the same therein. The electric terminals are inserted into the guide holes. Each of the electric terminals is connected at one end thereof to a rear surface of the electroluminescence panel, and at the other end thereof to a circuit board.
