摘要:
A timepiece for receiving a broadcast time signal containing correct time data for correcting a time error. A control circuit controls reception of the broadcast time signal depending on a time error. A current time is counted, and a time error dependent on the correct time data and the current time is determined for adjusting the current time. The reception of the broadcast time signal is controlled at intervals or times which are dependent on the time error obtained at a preceding adjustment operation so that the reception operation is executed only when necessary, thereby reducing power consumption.

摘要:
A printing method to increase the printing speed of a dot printer. Before printing on the basis of the dot data representative of an original dot pattern showing fonts, graphics end the like, the original dot pattern is converted by converting M (M.gtoreq.3) dots successive in the line direction into N (M>N.gtoreq.2, M.noteq.2N) dots. Then, printing is performed on the basis of the thus converted dot data. In a modification, conversion is performed by converting each dot into n (n.gtoreq.2) successive intermediate dots in the line direction and when 2n or more intermediate dots are successive, selecting every m{(2n-1).gtoreq.m.gtoreq.(n+1) }-th intermediate dot. In another modification, pattern conversion is effected by converting each dot into n(n.gtoreq.2) successive intermediate dots, in a zone where printing is possible at the same dot interval as that of the original dot pattern, selecting only dots out of the intermediate dots that are arranged at the same dot interval as that of the original dot pattern, and in the other zone, selecting every m{(2n-1).gtoreq.m.gtoreq.(n+1) }-th intermediate dot.

A font pattern to be stored is created by sequentially forming exclusive logical sums neighboring first bit patterns A1-A20 to form a plurality of second neighboring bit patterns B1-B20; designating at least one or more than one bit pattern which appears most frequently in the plurality of second bit patterns as a reference bit pattern, comprising and storing the difference of each bit pattern of the plurality of second bit patterns and the reference bit pattern per each bit pattern, and storing only the bit patterns which differ from the reference bit pattern in the plurality of second bit patterns.

Melodies are 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 are always played at predetermined hours, respectively. In addition, even if the hours and the melodies become discordant 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. In response to a correct hour signal supplied thereto, the alarm control circuit outputs the incorporated melodies sequentially and plays each melody through a speaker. When supplied with a reset signal, the alarm control circuit makes the alarm melody which is to be output next coincident with the first melody.
