Abstract
A wireless transmitting-receiving apparatus for detecting and displaying the speed of travel of a bicycle which is mounted on a wheel, including a sensor generating one signal per every rotation of the wheel, a signal receiving apparatus for successively receiving signals generated from the sensor, a pulse signal generator generating at least two pulse signals with a prescribed pulse interval for every generated signal, a wireless transmitter for transmitting continuously the generated pulse signals, a receiver for successively receiving the transmitted pulse signals, a converter for converting the received pulse signals into signals corresponding to the inputted signals based on the prescribed pulse interval, a microcomputer for calculating the speed of travel of the bicycle, distance traveled, and other similar functions of the bicycle, and a displaying portion for displaying the calculated speed of travel and other data.
