TELEPHONE SET

PURPOSE:To preferentially perform call origination and call termination at reserved time by deciding whether it is under speaking or not when present time is matched with the reserved time after the reserved time is set, and reporting that the reservation is executed to a user at the present time when it is under speaking. CONSTITUTION:A reserved time setting part 13 outputs the set reserved time information to a set time detection part 14. The set time detection part 14 decides whether the present time supplied from a present time count part 12 is matched with the reserved time supplied from the reserved time setting part 13 or not and when they are matched, a match signal is outputted to a control circuit 16. When the matched signal outputted from the set time detection part 14 is inputted, the control circuit 16 decides whether it is under speaking or not by using a speaking state detection part 15. When this decided result shows the state under speaking, an alarm sending part 9 is controlled, an alarm signal is outputted, and an alarm is generated from a speaker 10. On the other hand, just after the control of the alarm sending part 9 is started, the output interval of the alarm signal is controlled by a timer 11.
