<p>PURPOSE:To improve the picking work efficiency by switching a display section from the first display mode to the second display mode without erasing the numerical display on the numerical display section when a completion action piece is operated. CONSTITUTION:When indicator lamps of display units 151-15n are blinked, a picking worker performs the picking work extracting the objects stored at positions corresponding to the numerically displaying display units 151-15n by the directed quantity, and the worker pushes the completion buttons of the display units 151-15n under numerical display when the work is completed. Individual bay controllers 191-19n leave the numerical displays of the display units 151-15n as they are without erasing them and switch the indicator lamps of the display units 151-15n to the lighting drive. The picking worker can easily confirm the objects extracted during the work and the extraction number and the like on the spot. Picking errors are reduced, and the picking work efficiency is improved.</p> |
