PURPOSE: To seek to supply the desired panel preferentially by exiting plural panel absorbent unit provided with electromagnetic and releasing excitement at the specified position after transferring on plural run ways respectively.

CONSTITUTION: Plural panel absorbent units 22 consisting of brackets hanging electromagnets are so placed as to be free in running in a guide member 21 having plural run ways 25, 25a, 25b by a driving device. For each of these panel absorbent units 22, the electromagnet is excited at one end 23 part of the run way and the panel is absorbed and in that condition, the unit is transferred to each branch way 25, 25a, 25b. Then the desired panel absorbent unit 22 is sent to the other end of the run way 24 from the branch way according to the priority order. And the excitation of the electromagnet is released and the panel being held is sent to a reading part. Accordingly, the desired panel can be taken out preferentially regardless of the panel receipt order.
