Abstract
PURPOSE:To provide an interval timer which generates announcing sound at plural time intervals by providing with two or more memory counters which store timer times. CONSTITUTION:The 1st timer time is inputted to the 1st memory counter 17 with the 1st switch 15, and the 2nd timer time is inputted to the 2nd memory counter 20 with the 2nd switch 18. When a timer is started, a change-over circuit 21 selects the 1st memory counter 17, and sets the content thereof in a digital counter 22. Subtraction counting is accomplished by the 1-second signal from a control circuit and when a gate 23 detects the end of counting, the change-over circuit 21 sets the contents of the 2nd memory counter 21 and subtraction counting is accomplished. The operation of setting the content of the 1st memory counter 17 again in the digital counter 22 is repeated when the gate 23 detects the end of the counting. The announcement with a buzzer is accomplished every time at the ending of the counting.
