<p>PURPOSE:To lighten the load of a driver by eliminating the operation of a data read-out device in each time by installing a load detecting means for detecting the load of a fork and read-out-operating a recording medium read-out device in accordance with the variation of the load. CONSTITUTION:A data carrier read-out device RE is installed on the supporting member for a lift bracket 6, and communicates transmission with a rack data carrier CD1 and a pallet data carrier CD2, and reads out the data stored in these carriers, and transports the data into a controller 11. A hydraulic sensor 15 is turned ON when the pallet is lifted, while turned OFF when the pallet is lowered, and a position sensor 16 detects if a fork 5 is in rising, lowering, or stop state from the selection position of a control valve 19. The controller 11 judges if the fork 5 is in rising or lowering operation by a position sensor 16 on the basis of the turning-ON/OFF state of the hydraulic sensor 15, and if it is judged that the fork 5 is in rising or lowering, the data carrier read-out device RE is operated.</p> |
