Title:
歩数計
Document Type and Number:
Japanese Patent JP4885664
Kind Code:
B2
Abstract:
To enable to measure a number of steps highly accurately by dispensing with an operation of selecting a measuring mode when the number of steps is measured in walking and in running. A detecting signal detected by a walking sensor 101 is amplified and outputted by first amplifying means 103 by way of charge-voltage converting means 102. When a detecting signal 2B by way of only the first amplifying means 103 of the first and the second amplifying means 103, 106 is inputted to an input 2 of CPU 108, CPU 108 determines that a measured person is running, sets a mask time period or the like for running and carries out a processing of calculating a number of steps based on the detecting signal 2B. When the detecting signal 2B by way of only the first amplifying means 103 is not inputted to the input 2 of CPU 108 and a detecting signal 1B by way of both of the first amplifying means 103 and the second amplifying means 106 is inputted to an input 1 of CPU 108, CPU 108 determines that the measured person is walking, sets the mask time period or the like for walking and carries out the processing of calculating the number of steps based on the detecting signal 1B.
