Within. And the intended compartment storage space 1C,
The group of movable shelves 2 is moved so that a work space S is formed in front of 2C. The movement of the two groups of movable shelves is performed by a central control device.
An instruction signal from 39 is supplied to the target control device 36 via the main cable 40 and the sub-cable 38, and an instruction signal from the control device 36 is supplied to the movable shelf 2 via the branch cable 37. I can do it. That is, the collarless wheel 7 is forcibly rotated by the motor 10 based on the instruction signal, and the movement is performed on the fixed path 11 while being supported on the rails 8 and 9 via the wheels 5 and 7. At this time, the movement control signal is transmitted and received, for example, the light emitted from the photoelectric switch 12 is reflected by the reflection plate 13, so that the movement of the movable shelf 2 is controlled without collision.

With the work space S thus formed, the empty access device 26 is moved in the front-rear direction by the support and guide of the guide portion 24a, and is positioned outside the end of the work space S. Next, the loading truck is supported by the rails 17
16 is moved from the home position H toward the loading / unloading device 26, and stopped at a position close to the loading / unloading device 26. In this state, a combination operation of the raising / lowering movement of the carriage 30 and the movement of the loading / unloading tool 31 is performed, so that the load 33 on the load receiving truck 16 is moved through the loading / unloading tool 31 to the loading / unloading device 26.
