PURPOSE:To generate a pace for taking exercise while conforming to pitch sounds with a period, which can be adjusted and is accurate, by using a ring oscillation circuit for adjusting oscillating frequency by means of a variable resistor, and by producing said pitch sounds in order to take safe and healthy exercise. CONSTITUTION:In a time pace generator for displaying pace signals by sound waves, the control of the start, stop, reset, etc. of the action of the system and the setting of the frequency of pitch signals are performed by means of a set mechanism 202, and pace signals are generated from a pace signal generating source provided with an oscillator of variable frequency. This circuit is equipped with a variable frequency ring oscillation circuit for adjusting oscillating frequency by means of a variable resistor, and drives a drive circuit 206 to display sound production from a sound production body 208. Meanwhile, a time base generating source 210 is provided with an oscillator of fixed frequency, and time marker signals are generated by means of a timing mechanism 212 furnished with an electronic counter circuit. |
