<p>PURPOSE:To improve safety of operation by allowing a transmitting device which makes a signal first and the foremost, to preferentially perform a passage forming action in the captioned device which juxtaposes freely mobile shelves closely to each other and enabling passages to be formed between shelves correspondingly to output of the plural number of transmitting devices. CONSTITUTION:On a mobile shelf device composed of the plural number of juxtaposed shelves, only one of which positioned on one end of the row is a fixed shelf while the others are converged as the whole and further separate from each other and mobile so as to enable formation of work passages between them, correspondingly to the plural number of transmitting devices (illustration omitted) provided for remote control of this mobile shelf device, the same number of receiving circuits 37a-37c as the transmitting devices are provided in control devices of the captioned device. Supply of power source to these receiving circuits 37a-37c is performed through placing contact points L11-L31 of relays L1-L3 in ON state. Further, each relay L1-L3 is formed as an interlocking circuit to stop its action in case a signal is inputted from a transmitting device other than an initially operated transmitting device.</p> |
