Abstract
A timepiece device with multiple-hand which can be miniaturized and made thin as a whole has a configuration where a hour hand hour wheel positioned close to an hour hand to which a rotation movement of a 3rd motor via an hour hand gear train mechanism and a functional hand hour wheel positioned close to a functional hand to which a rotation movement of a 4th motor via a functional hand gear train mechanism are arranged on a front side of a support plate, and a 4th wheel positioned close to a second hand and a 2nd wheel positioned close to a minute hand are arranged on a rear side of the support plate.
Claims4
A timepiece device with multiple-hand comprising:
- a plurality of hands;
- a plurality of driving motors each of which individually drives each of the hands so that the hands rotate;
- one or more gear train mechanisms each of which includes a plurality of gears for transmitting a rotation movement of each of the driving motors to each of the hands;
- and
- a support plate which supports the gears;
- wherein the hands include an hour hand, a minute hand and a second hand provided above a first side of the support plate, to which hands the rotation movements of first to third driving motors among the driving motors are transmitted via first to third gear train mechanisms among the gear train mechanisms, respectively;
- wherein the driving motors are provided on a second side of the support plate,
- wherein among the gears of the first gear train mechanism which transmits the rotation movement of the first driving motor to the hour hand, at least a gear which is positioned close to the hour hand is arranged above the first side of the support plate,
- wherein among the gears of the first gear train mechanism which transmits the rotation movement of the first driving motor to the hour hand, one gear has a first and second gear members provided on two sides of the one gear respectively, the gear members meshing with gears which are different from each other above the first side of the support plate and below the second side of the support plate respectively,
- wherein the gears of the second or third gear train mechanism, which transmits the rotation movement of the second or third driving motor to the minute hand or the second hand, are arranged below the second side of the support plate, and
- wherein a gear train mechanism composed of the gears positioned above the first side of the support plate, among the gears of the first gear train mechanism which transmits the rotation movement of the first driving motor to the hour hand, is arranged opposite to the second or third gear train mechanism composed of the gears which transmit the rotation movement of the second or third driving motor to the minute hand or the second hand, across the support plate.
