<p>PURPOSE:To make a worker judge object load storage blocks accurately through a light emitting display part which is illuminating by installing the light emitting display part which displays the load storage blocks for carrying-in and-out in a tray in parallel to each other for the respective load storage blocks. CONSTITUTION:A controller is operated according to a tray call command which is sent by a computer so force at the time of carrying-in and-out work, and a tray 3 for carrying-in and-out work is rotated in a vertical circulating passage, and the tray 3 is called and automatically stops at a call position P. Among load storage blocks 7 in the tray 3 for carrying-in and-out which is stopped at the call position P, a light source 15 corresponding to the load storage block 7 for carrying-in and-out work is energized to be lighted. The light of the turned-on light source 15 is condensed at a condenser lens 12a through a light receiving window 12 corresponding to the load storage block for carrying-in and-out work among the plural receiving windows 12 which the tray 3 stopping at the call position P owns, and transmitted to the light emitting lens 10a of a light emitting display part 10 which is connected by an optical fiber cable 13.</p> |
