Abstract

PURPOSE:To obtain a pace-maker whose sounding rhythm beats quick in order, by selecting and sounding one periodic signal which becomes quick in order. CONSTITUTION:When a changeover switch S3 is closed,the display is switched through a T-type FF21 and the devicd becomes a pacemaker mode. Subsequtly, by a start switch S2 and a multivibrator 10, an up-down counter 17 becomes an up-counting state through a T-type FF23, and a counting value of the counter 17 becomes ''1'' by an output of the multivibrator 10 through an OR circuit 16. As a result, an AMD gate 8a is opened, and a pulse signal of a long period from a timging signal genertating circuit 6 is applied to a sounding device 19. On the other hand, a signal of a prescribed period from the circuit 6 passing through an AND gate 7a is counted by a counting value ''0'' of a pase counter 12, and after 60 seconds have passed, a counting value of the counter 17 is stepped forward by a carry signal outputted from a counter 15, an AND gate 8b is opened, and a quick periodic signal is applied to a device 19. In this way, it is possible to obtain a pace-maker which is slow at the time of start and beats quick in order in the same way.
