PURPOSE:To shorten access time of a unit from which a stored material is frequently drawn, and to improve usability by preliminarily moving the unit to the vicinity of an opening. CONSTITUTION:Eight units 6 are stored in a storing case 2. A material stored in the unit 6 opposed to an opening part 3 is drawn from above by opening a lid 4. An X-Y table 11 is provided, and the unit 6 can be moved freely on a shelf plate 6a by a ball caster 13. A data table with regard to time, day, and to the unit 6 which is considered to be most frequently used at the time, is stored in a memory of an operational panel 5. The unit 6 which is considered to be highly possibly used at a present time, is preliminarily so controlled as to be in the vicinity of the opening part 3. An average value of access time, or time needed for moving the unit 6 to the opening part after it is selected, is shortened by the control. |
