An alarm setting mechanism for an electronic timepiece has a linkage for converting displacement of an alarm activating stem into a larger displacement of an alarm status indicating member which traverses an arcuate path on the front face of a dial of the timepiece. An alarm switching mechanism sets an alarm by activation of a stem on the timepiece which is connected to the alarm status indicator and the alarm switching mechanism. The linkage includes a pivotable switching lever, a pivotable set...

A correcting lever is integrally provided with a correcting portion for correcting a fifth wheel, a reset portion brought into contact with a reset pin for stopping an output of a pulse signal from an IC, a return spring portion and an engaged portion and is rotatably supported about a rotary center portion (hole) to a base plate. An engagement portion of a winding stem is engaged with the engaged portion by operation of drawing the winding stem and the correcting lever is shifted against the bi...

A multimode electronic timepiece includes a display, an audible alarm device, a plurality of manually actuated switches, and an integrated circuit programmed to keep time and to provide a plurality of modes including time-of-day, alternate time zone and alarm setting modes. The integrated circuit is programmed to permit an operator to set time-of-day in response to actuation of selected switches, to set alternate time zone time in response to actuation of selected switches, and to set alarm set ...

An alarm mechanism system, comprising: an hour wheel, completing one turn every 12 hours; a ring gear, concentrically surrounding the hour wheel; a planet gear device, engaging with the hour wheel and the ring gear and, driven by the hour wheel, completing one turn every 24 hours; an alarm device, which contacts the planet gear device at a predetermined time within one turn of the planet gear device and issues an alarm at that time; and an adjustment device to adjust the predetermined time. The ...

An electronic alarm clock including a clock timing circuit for counting the basic time, an alarm time setting circuit for setting an alarm time and an alarm time storing circuit storing said alarm time. The electronic alarm clock also includes an alarm coincidence detecting circuit for detecting the coincidence between the basic time and the alarm time stored in said alarm timing storing circuit, an alarm setting/resetting circuit and an alarm sounding control circuit for causing an alarm soundi...

A radio-controlled timepiece includes a clock face, a hands assembly mounted for rotation about an axis in front of the clock face, and an alarm setting mechanism. The alarm setting mechanism comprises a minute setting disk which is driven by an hour setting disk. A manually rotatable transparent support disk is mounted in front of the clock face for rotation about the same axis as the hands assembly. The support disk carries a marker which, when the support member is rotated, is moved to indica...

A wristwatch with an alarm time-setting function includes a clock case having a hollow accommodating space, a clock mechanism mounted in the accommodating space, and a rotary drive ring mounted rotatably on the front side of the clock case. The wristwatch further includes a timer-setting member accommodated inside the accommodating space and connected to a timer-setting pin of the clock mechanism. A driving member of the rotary drive ring is disposed inside the accommodating space to engage a dr...

A clutch assembly has a driving assembly and a transmission assembly. The driving assembly has an input axle and at least one driving gear. The transmission assembly is connected to the driving assembly and has an output axle, at least one driven gear, an inner axle and a unidirectional transmitting device. The driven gear is rotatably mounted on the output axle and engages with the driving gear. The inner axle is slidably mounted in the output axle and is engaged with the output axle to rotate ...

A multifunction electronic analog timepiece includes a face and a plurality of indicators positioned on the face for displaying at least two time keeping functions. At least two step motors are provided for driving the plurality of time keeping function indicators. The time keeping function indicators are arbitrarily disposed about the face dependent upon the number of step motors and position of step motors required to drive the indicators. A microcomputer is provided and includes a program mem...

A multimode electronic timepiece has a display, an audible alarm device, manually actuated switches, and an integrated circuit programmed to provide several operating modes. The modes include a first mode in which an alarm sounding setting is displayed, which is alterable in response to actuation of a selected setting switch. The modes include a second mode in which said alarm sounding setting is not displayed, but in which said audible alarm device may be disabled by actuation of a selected dis...
