PURPOSE:To make it possible to perform the alteration of a pace value in a sensation signal generation state, by respectively independently providing a switch for controlling the generation of a pace signal as an external operation switch and a switch for increasing or decreasing phase memory information. CONSTITUTION:A register 12 counts the pulse signal generated in an input apparatus 11 and stores a numerical value M as numerical value information. An oscillator 15 generates a reference frequency signal which is, in turn, guided to the reset terminal of a counter 18 to be guided to the input terminal of the counter 18 through an AND gate 17. A comparator circuit 14 detects the coincidence of the output of the counter 18 and the numerical value M to controls the gate 17. The output pulse of the gate 17 is applied to a sounding apparatus 20 through a frequency divider 19. Switches S1-3 are independently provided to the apparatus 11. A signal ST is generated by S1 to start the operation of a pacemaker and the numerical value M receives increase or decrease control by S2 or S3. By this method, the apparatus 20 can be altered in a pace value in an operation state. |
