<p>PURPOSE:To prevent the restraint of a moving range by providing a means which can transmit and receive data by radio. CONSTITUTION:A battery 1 supplies power sources to each part, a rotation detecting part 3 detects the rotational direction and the number of time of rotation by rotating a roller part 4, and transmits the data to a controlling part 2. The controlling part 2 transmits the data to a radio module part 5, and the radio module part 5 modulates the data for the radio. Then, radio waves are radiated from an antenna part 6, the radiated radio waves are received by a personal computer PC and processed as the data. Like this, this device is equipped with the means which can operate a data communication with the personal computer or the like by radio. Thus, the restraint of the moving range due to lines is prevented by removing the lines.</p> |
