Abstract

1523993 Electronic alarm timepieces DAINI SEIKOSHA KK 6 Oct 1976 [15 Oct 1975] 41594/76 Heading G3T In an electronic alarm timepiece, an audible alarm device 20 is operated by a driver 19 when comparison circuits 6, 7 detect coincidence between the content of time of day counters 4, 5 and pre-set alarm, time in counters 9, 10, also when a detector 21 detects that the battery voltage has fallen below a predetermined level. Selective operation of a switch 30 enables changeover circuits 11, 12 to apply the actual time of day data or the pre-set alarm time data to decoder/ drivers 13, 14 for display or on electro-optical digital display devices 15, 16. The alarm time is settable by a circuit 8 in response to operation of a switch (not shown).
