Abstract: PURPOSE: To maintain smooth conveyance in high efficiency without temporaty stop of the article to be conveyed by shifting its posture shifting it in the direction of conveyance.  
     CONSTITUTION: When a plate body 5 is conveyed from the right as shown by the arrow and shifted onto an air table 1, the plate body 5 contacts a buffer plate 11 connected with the endless conveyor 6 on the lower part side due to the inclination of the air table 1. When the plate body 5 is conveyed by the endless conveyor 6 and reaches a prescribed position on the right from the center of turning of an arm 23, an attracting device 24 which stands ready is lowered by a cylinder mechanism 25 and attracts the plate body 5. Then, a cylinder mechanism 28 operates and turns the arm 23 in the advancing direction of the endless conveyor 6 and turns the plate body 5 in the floated state on the air table 1. When the revolution is completed untill the front edge of the plate body 5 contacts the endless conveyor 6, the attracting device 24 is released and raised. Then the arm 23 returns rightward and waits the next body.
