PURPOSE:To detect automatically the pace of motion by not only displaying the pace but also producing a pace tone with the signal of a sensor which detects the acceleration which is generated when the user shakes his arm. CONSTITUTION:An arm shake pace is grasped by a sensor circuit 4 and a sensor output P1 of 5 pulses, namely, 4 periods of the circuit 4 is detected, and an average pace at this time is displayed on a display device 10, and a pace tone is produced by the pace which is operated synchronously with the sixth pulse of the sensor circuit 4. The pace of user's motion is detected similarly at every certain period by a start signal S11 or a lap signal S2, and a new operated pace and the pace tone are outputted. |
