Filed: 1974-07-17
Abstract: 1446117 Electronic watches SUWA SEIKOSHA KK 17 July 1974 [9 Aug 1973] 31682/74 Heading G3T An electronic timepiece e.g. a watch with a liquid crystal or light emitting diode time display and a time indication correction circuit, has a correction locking circuit to prevent accidental operation of the correction circuit. In an embodiment Fig. 2, a correction circuit A produces a correction signal for the time indication parts other than the seconds indication, and always produces a logic "1" signal. When a signal from a locking signal generator ALS (operated by a switch, not shown) is logical "1", the correction signal is blocked by a gate G. When the locking signal is "0" the correction is possible and simultaneously a seconds counter SC is reset to zero by the inverted locking signal acting on a seconds reset circuit SR. Counting of a clock signal from a source CL is thus prevented until time correction is completed and the locking signal returns to logic "1". In another embodiment Fig. 4 (not shown), an AND gate (H) receives the locking signal from ALS both directly and via a delay circuit in series with an inverter, and during coincidence of its two in puts produces a signal which is applied to the seconds reset circuit SR. In a further embodiment Fig. 6, a gate J receives the clock signal from CL and an inverted correction locking signal. The seconds counter SC does not count the clock signal when the inverted locking signal is "1" i.e. when correction is permitted. When the inverted locking signal is returned "0" further correction is prevented. The seconds counter is not reset to zero and after correction action starts counting at the same count whereat it stopped. In an acknowledged known arrangement Fig. 1 (not shown) a locking signal acts on locking circuits (E 1  E 2  E 3 ), e.g. OR gates, to prevent correction signals passing from respective correction circuits SA, SM, SH for secs, mins and hours, to the counters.
