<P>PROBLEM TO BE SOLVED: To provide a liquid discharging device which is capable of successfully driving with a small driving force and moreover is intended to enhance durability by reducing friction between a pressing object and a tube. <P>SOLUTION: The liquid discharging device 1 is provided with a tube 3 at the inside of which liquid flows through, balls 4 as the pressing object, and a driving mechanism 5 which drives the balls 4. The driving mechanism 5 is equipped with an energy accumulating means which accumulates at least one of mechanical energy, potential energy and thermal energy, an energy transmission means which transmits energy from the energy accumulating means as the driving fore of the balls 4, a driving part which drives the balls 4 based on the energy transmitted by the energy accumulating means, and a governor means which governs the driving speed of the driving part. The balls 4 move liquid in the tube 3 by rolling on the tube 3 while pressing and closing a part of the tube 3 by driving the driving mechanism 5. <P>COPYRIGHT: (C)2004,JPO |
