Movement device utilizing electromechanical conversion elements and control method therefore

A movement device for moving an object relative to the movement device comprising:

• a body;
• at least one first electromechanical conversion element, fixed to said body, which expands and contracts in a direction of relative movement;
• at least one second electromechanical conversion element, fixed to said body, which expands and contracts in a direction approximately perpendicular to the direction of relative movement;
• a first block connected to said at least one first electromechanical conversion element;
• a second block, spaced from and separate from said first block, connected to said at least one second electromechanical conversion element;
• and
• a voltage supply unit which supplies a voltage to said at least one second electromechanical conversion element such that the object comes in contact with said first block and separates the object from said second block, and thereafter supplies a voltage to said at least one first electromechanical conversion element such that said first block moves in a first direction relative to the object, and thereafter supplies a voltage to said at least one second electromechanical conversion element such that said second block and the object come into contact and said first block and the object become spaced apart, and thereafter supplies a voltage to the at least one first electromechanical conversion element such that said first block moves in a direction opposite to the first direction relative to the object.
