SOLUTION: This control panel is composed of a display content generating means 6 for generating the contents held in the display content holding means according to the direction determined by a display direction determining means 5 and a display means 8 for displaying the display contents generated by the display content generating means 6 or the like. Then, signals generated by 1st and 2nd signal generating means A and B (2 and 3) are received by a signal receiving means 4. Based on these signals, the position relation of the 1st and 2nd signal generating means A and B (2 and 3) is found by the display direction determining means 5. Based on this position relation, the display content generating means 6 determines the direction to display the display contents.</p> |
