Abstract

1526469 Electronic alarm timepieces DAINI SEIKOSHA KK 6 Oct 1976 [15 Oct 1975] 41593/76 Heading G3T An electronic alarm timepiece has aural and visual alarm means and selector means whereby either alarm mode may be selected as desired. As shown, comparison circuits 6, 7 produce outputs to open AND gate 17 when the contents of minutes and hours counters 4, 5 coincide with the alarm time pre-set in minutes and hours alarm time storage counters 9, 10. The AND gate output is directed by a selector circuit 18 to the driver 19 of an audible alarm 21 or to the driver 20 of a flashing L.E.D. visual alarm 25. The selector circuit 18 is conditioned by a switch (not shown) to select the alarm mode. An alarm setting circuit 8 is set by means of an external switch (not shown) and produces an output to set the alarm time storage counters 9, 10 when a switch 30 is closed to terminal H. In this state of the switch 30 the content of the counters 9, 10 is coupled to de-coder/drivers 13, 14 by changeover circuit 11, 12 so that display devices 15, 16 will display the alarm time. When the switch 30 is closed to terminal L the contents of the time of day counters 4, 5 are coupled by the changeover circuits 11, 12 to the de-coder drivers 13, 14 to give a time of day display.
