1. A pace timing device, comprising:
- oscillator circuit means for generating a standard frequency signal;
first frequency divider means coupled to receive said standard frequency signal and responsive thereto for producing a first frequency division signal and a second frequency division signal having a frequency lower than that of said first frequency division signal, said second frequency division signal comprising N pulses per minute;
input means, for inputting electrical signals representing a numeric value M, where M is a positive integer;
memory means for memorizing said numeric value M from said input means;
pulse group generating circuit means coupled to receive said first and second frequency division signals and signals from said memory means representing said numeric value M, and responsive thereto for producing successive groups of pulses, each of said pulse groups comprising M pulses, and with the period between the initiation of each of successive ones of said pulse groups being equal to 1/N minutes;
second frequency divider means coupled to receive said groups of pulses from said pulse group generating circuit means and for performing frequency division thereon by a factor 1/N, for thereby producing output pulses at a frequency of M pulses per minute; and
perceptible signal generating means coupled to receive said output pulses from said second frequency division means, for producing physically perceptible pace timing signals at timings controlled by said output pulses.

Abstract
An electronic pace timing device whereby a physically perceptible pace timing signal can be repetitively generated, and whereby the repetition frequency of this pace timing signal can be set into the pace timing device as a numeric value, by actuation of external operating members. No calculations are performed in order to convert the numeric value specifying the repetition frequency of the pace timing signal into an actual pace timing signal, so that the overall circuit configuration can be very simple.
