PURPOSE:To aim at the promotion of high accuracy for positioning, by depressing a second movable body after engaging a lot of plate members aligned in a feeder mechanism by a positioning guide, with a first movable body through an extruding block, and making the second movable body go up to a position where a robot hand grips in the engaged state. CONSTITUTION:When a lot of plate members W are set to a feeder mechanism 1, side surfaces are aligned by a guide plate 3 and upper and lower surfaces by a guide rail 4, respectively, and a plate member W1 at the endmost is engaged with an engaging surface 17 of a first movable body 13 of a pushing mechanism 2 by an extruding block 5. Next, when a robot hand 100 depresses a head part 14a of a second movable body 14, the first movable body 13 goes up whereby the member W1 is pushed up to a space between fixed and movable claws 101 and 102 of the hand 100. When the movable claw 102 grips the member W1 with help of an actuator 103 and shifts to an assembling part, the movable body 14 moves upward by dint of a spring 19 while the movable body 13 returns whereby the next member W is engaged. Accordingly, the plate member can be positioned in a highly accurate manner without installing the actuator or the like in a device itself.
