<p>PURPOSE:To carry a material to be carried at constant velocity with accuracy by reading information concerning diameter corresponding to a circumference direction and a rotating angle from a reference position of a rotor detected by a detector means, from a storage means, and by forming a control means to control angular velocity of the rotor so as to maintain constant carrier velocity for a material to be carried. CONSTITUTION:Information concerning diameter corresponding to a circumference direction and a rotating angle from a reference position of a rotor 12 when the rotor 12 such a roller is rotated at constant angular velocity is preliminarily stored in a storage means 31. Then, a circumference direction and a rotating angle from a reference position of a rotor 13 are detected by a detector means 13, and based on the detected value and the content of the storage means 31, angular velocity of the rotor 12 is controlled by a control means 53, for a material to be carried 23 to be carried at constant velocity.</p> |
