Abstract
PURPOSE: To produce a large suction force at all times by providing a power source circuit which provides positive and negative charges to a pair of electrodes thereby preventing reduction of suction force due to charging of environment.
CONSTITUTION: A power source circuit 10 provides positive and negative charges to a pair of electrodes 4, 6. When the polarity of D.C. power source 14 is switched through a switching section 16 and opposite charges are fed to the pair of electrodes 4, 6, electricity is induced in a suction mechanism 8. When a material 12 to be sucked contacts with the suction mechanism 8, charges having different polarities are produced to provide suction force thus sucking and holding the material 12. When opposite charges are provided respectively to the pair of electrodes 4, 6, reduction of suction force due to charging of environment can be prevented without influence of temperature or humidity and a large suction force can be produced at all times.
