The GUI screen image 50e displays a directional keys input area (52) at the lower left on the screen image, a button input area 56 at the lower right, an L1/L2 button input area (80) at the upper left, and an R1/R2 button input area (82) at the upper right. The L1/L2 button input area (80) and the R1/R2 button input area (82) are in the forms of circle sectors, whereby the center angles of the circle sectors are the right angles of the two upper corners of the screen, and by internally dividing the center angles further so as to divide the sectors into two sectors respectively, the L1 button and the L2 button, and the R1 button and the R2 button are distinguished.</p> |
