1. A pace display device comprising:
- step sensing means for sensing steps taken by an exerciser in each of a plurality of sections of a jogging course to obtain step number data;
timekeeping means for measuring a lap time required by the exerciser to complete each section of the plurality of sections of the jogging course;
pace calculating means for calculating an average pace for each of the plurality of sections of the jogging course on the basis of step number data obtained by said step sensing means and the lap time measured by said timekeeping means;
first storage means for storing the average pace for each of the plurality of sections of the jogging course calculated by said pace calculating means;
pace difference calculating means for calculating a pace difference between an average pace for two adjacent sections of the jogging course stored in said first storage means;
second storage means for storing the pace difference calculated by said pace difference calculating means, in correspondence with one of the average paces used to calculate said pace difference; and
display means for displaying the average pace stored in said first storage means and the pace difference stored in said second storage means, which average pace was used by said pace difference calculating means to calculate said pace difference.

Abstract
When a lap switch is operated, data of a lap time stored in a register T is stored in a lap register pointed out by a pointer PR. An average pace for a section of a course is calculated on the basis of data of a step count for that section stored in a register H and data on the lap time for that section stored in the register T. Data on a calculated average pace is stored in a lap register. A pace difference between the present and the immediately preceding average pace is calculated and data on the pace difference is stored in an appropriate lap register. Thereafter, the pointer PR is incremented by one.

4. A pace display device comprising:
-
step counting means for counting steps taken by an exerciser to obtain step number data; time counting means for counting a lap time; step number storage means for successively storing step number data obtained by said step counting means each time said time counting means counts a predetermined time duration, the predetermined time duration being equivalent to a time duration obtained by dividing a unit time by a predetermined number; pace calculating means for summing up said successively stored step number data stored in said step number storage means each time said time counting means counts the predetermined time duration, to calculate a number of steps taken by the exerciser during the last unit time, whereby pace data representing a number of steps taken by the exerciser during the last unit time is obtained; and display means for displaying the pace data obtained by said pace calculating means each time said time counting means counts the predetermined time duration. - View Dependent Claims (5)

6. A pace display device comprising:
-
step counting means for counting steps taken by an exerciser who jogs along a jogging course that includes several sections to obtain step number data representative of a number of steps taken by said exerciser in each section; time counting means for counting an elapsed time; average pace calculating means for calculating an average pace for each section of the jogging course from the elapsed time counted by said time counting means and the step number data obtained by said step counting means; average pace storage means for storing the average pace calculated by said average pace calculating means; step-number storage means for successively storing step number data which have been obtained by said step counting means every time said time counting means counts a predetermined elapsed time; externally operable means; pace calculating means for calculating a number of steps taken by the exerciser in a unit time from step number data stored in said step-number storage means, when said externally operable means is operated, whereby pace data representative of a number of steps taken by said exerciser, for each unit time is obtained; pace difference calculating means for calculating a pace difference between the average pace stored in said average pace storage means and the pace data calculated by said pace calculating means; and display means for displaying the pace difference calculated by said pace difference calculating means and the pace data obtained by said pace calculating means.
