BOARD CARRYING METHOD AND DEVICE THEREFOR

摘要

It is arranged that boards can be carried in and out of optional shelves in a board cassette. When it is desired to carry out a board (1G) stored in each shelf (1R) formed as a shelf plate by use of a plurality of wires (4) attached under tension to a cassette main body (1) constituting a board cassette (1C), this is achieved by moving board lifting arms (14) constituting a pair of board lifting units (1U1) onto a shelf (1R') immediately below the shelf (1R) having the board (1G) stored therein, actuating a pneumatic floating unit (21) attached to the upper surface of each board lifting arm (14), and spouting pressure air to extract the board (1G) in its floating state.
