PROBLEM TO BE SOLVED: To enlighten safety work every day by displaying symbol marks indicating 'read the instruction manual' and 'fasten the seat belt' on a screen every key operation for start of operation. SOLUTION: Figure 2 (b) shows a key ON state at start of operation such as the commencement of work, or immediately after a power source is closed, and symbol marks of a function set in a forklift and letters of 'monitoring' are displayed. After 0.5-1 second, the display is changed to figure 2 (c), a symbol mark 37 indicating 'read the instruction manual' and a symbol mark 38 indicating 'fasten the seat belt' are displayed. The symbol marks 37, 38 go on and off at least once, and the display is changed to a basic screen showing in figure 2 (d).
