| 摘要 | An alarm timepiece in which in the specific embodiment disclosed the alarm signals are melodies changed over sequentially in accordance with hours at each of which an alarm melody is to be played as a time signal so that predetermined melodies from a sequence of melodies are always played at predetermined hours, respectively. In addition, even if the hours and the melodies become out of phase with each other as a result, for example, of the correction of the time made during the timekeeping operation of the timepiece, the melodies are automatically reset at a predetermined time so as to be coincident with the corresponding hours. A switch S2 for detecting a correct hour is on-off controlled by a cam 6a provided as an integral part of a minute pipe 6 that makes one revolution per hour. A reset switch S3 is on-off controlled through a reset lever 5 pivoted by an hour wheel 4 that makes one revolution per twelve hours. An alarm control circuit in an IC 3 incorporates a plurality of melodies sequentially and plays each melody through a speaker SP. When supplied with a reset signal, the alarm control circuit makes the next alarm melody which is to be output the first melody in the sequence. | ||||||
