<p>PROBLEM TO BE SOLVED: To eliminate the need for the trouble to replace a battery and obtain a semipermanently maintenance-free mouse by equipping the mouse with a power generating means and a charging means. SOLUTION: The mouse has the power generating means 1 and charging means 2. The power generating means 1 consists of a roller which comes into contact with the ball part of the mouse and a power generator connected to its roller shaft, or a pendulum 3 and a power generator 5 connected to its pendulum shaft 4. The power charging means 2, on the other hand, consists of a battery charger 7 and a diode 6 which rectifies a voltage generated by the power generator 5. Then the pendulum 3 is swung by mouse operation and the power generator 5 connected to the pendulum shaft 4 is rotated to generate electric power. The electric power generated by the power generator 5 is rectified by the diode 6 and stored in the battery charger 7, and then used by an electric circuit in the mouse. Consequently, a disturbance by a cord and the damaging of the electric circuit due to a short circuit caused by the damage of the cord can be evaded and the trouble to replace the battery is eliminated.</p> |
