Then, insert the insole 11 on which the sensor 3 is installed into the shoe 10, and attach the main body 2 to the girder pick-up stand 4. When walking or running, the sensor 1 becomes electrically conductive each time the robot receives a human body load when it lands on the ground, and the main body 2 counts this electrical conduction. When this count value is displayed, the number of steps is displayed, and when the value obtained by multiplying the number of steps by the stride length is displayed, the distance is displayed. However, since this pedometer counts 1 for the shoe 10 on the i side, and the number of steps indicates the number of times one foot touches the ground, the number of steps at the top is twice the value. Also, even if the width is made smaller, the value of 2 fractions is manually input.Of course, even if it is processed electronically to show the original number of steps, and the stride length can be changed manually to the value of 1 step, nothing will happen. No problem.

1 Effects of the Invention 1 As shown in Jl [In the present invention, a main body equipped with a battery power source and display means and a sensor disposed on the part of footwear on which the foot is placed are connected via a lead wire, and the main body A device that is removably attached to the part of the footwear that holds the foot, which allows the sensor to reliably detect walking, running, and running motions, and at the same time allows the display device to be placed in an easily visible part. However, since the sensor can be separated from the main body by connecting the terminal provided at the end of the lead-out wire and the terminal that can be freely connected, it is easy to install a sensor that is prone to deterioration. In addition to being able to use the sensor for a long period of time by replacing the sensor, for example, if the sensor is installed in each pair of footwear and the sensor is removed after f'-1, the main body can be replaced. It is also possible to count the number of steps even when wearing footwear.
