Abstract

PURPOSE:To enlarge the snoozing function by making a one-shot pulse, which is generated by the output of a snooze switch, into a snooze signal so that a sleep timer counter may be reset in response to the pulse signals during the sleep operation. CONSTITUTION:Taking it into consideration that the sleep operation is controlled by a sleep display switch SLD, in order that the sleep time may be elongated by the operation of a snooze switch SN during the sleep operation or sleep display, the snooze switch signals are fed to a one-shot pulse generating circuit 13, and the soonze signals in a monocylic integrated circuit are used as pulse signals and made into the resetting signals of a sleep counter 10. The reason why the snooze signals are used as the pulse signals is to set the time elongating sleep counter 10 accurately at the longest time of 59 minutes.
