Abstract
An alarm timepiece is disclosed having hand display means in which a plurality of alarm times may be set and the set times are displayed. A plurality of alarm time indexes are circumferentially arranged and rotatably provided for indicating the setting of the alarm time by angular position of the index. Further, alarm time memory means is provided to be co-operated with each index and alarm time detecting means is provided to be operated by the time measurement means of the timepiece. Each memory means, alarm time detecting means and an electric alarm device are connected by electric circuits to operate the alarm device when the alarm time detecting means operates to close the circuit.
Claims8
An alarm timepiece comprising:
- a case having a dial face;
- at least one time indicating hand;
- time measurement means for generating a signal indicative of the time and for driving said at least one hand in response to said signal;
- an alarm;
- a plurality of time memory means, each of said time memory having a respective alarm time index rotatably mounted on a shaft, each of said time memory means for storing alarm energization information provided by the rotation of said shaft, said alarm energization information being stored in the time memory means corresponding to the time at which the alarm is to be energized, said respective alarm time index being rotated by said shaft to indicate the contents of its respective time memory means when said alarm energization information is stored, each of said time memory means having alarm energization information stored thereon energizing said alarm when the respective time said memory means is associated with is reached;
- a manually operated crown positioned outside the case;
- and
- alarm set means for transmitting the motion of said crown to a desired one of said respective alarm index shafts to provide said shaft with said alarm energization information.
An alarm timepiece comprising:
- a case having a 12 hr. dial face;
- at least one time indicating hand;
- time measurement means for generating a signal indicative of the time and for driving said at least one hand one revolution every 12 hours in response to said signal;
- an alarm;
- a plurality of time memory means, each of said time memory means having a respective alarm time index rotatably mounted on a shaft, each of said time memory means for storing alarm energization information provided by the rotation of said shaft, said alarm energization information including A.M. and P.M. information being stored in the time memory means corresponding to the time at which the alarm is to be energized, said respective alarm time index being rotated by said shaft to indicate the contents of its respective time memory means when said alarm energization information is stored, each of said time memory means having alarm energization information stored therein energizing said alarm when the respective time said memory means is associated with is reached, said shaft being rotated in a first direction to store A.M. alarm energization information and being rotated in a second direction to store P.M. alarm energization information.
