ABSTRACT:
An electronic pedometer for use on a footwear is disclosed. The pedometer comprises a step sensor carried by the footwear for sensing each step that the user takes to provide an output indicative thereof. Connected to the sensor is a mount base which is secured to the footwear and has thereon a first terminal electrically connected to the step sensor. A counter, which is detachably mounted on the mount base, has therein various electronic components forming a computing circuit and includes a display section. The counter is provided with a second terminal which comes into electrical connection with the first terminal on the mount base when mounted thereon so that the computing circuit receives the outputs from the sensor to compute based thereupon the number of steps taken and the distance travelled by the user. The resulting measurements of the computing circuit are visually indicated on the display section of the counter. Thus, the counter including the electronic components can be alone detached from the footwear while the mount base thereof and the sensor remain attached thereto, eliminating the troublesome procedure to remove the base mount secured to the footwear when the footwear is required to be washed as protecting the electronic components of the counter from being damaged during that washing. Accordingly, the convenience of using the pedometer on the footwear is greatly enhanced, leading to a widespread use of the pedometer.
