PROBLEM TO BE SOLVED: To economize memory resources and to accelerate displaying of images by reducing a data capacity for transparently displaying a movable accessory. SOLUTION: Two or more picture patterns 51 to 56, sprite pictures in a background and the coordinates of respective apexes A, B, C and D of a reel display window 6 are stored in a memory of a picture display control part. When a command including designation of transparent display of reels 3a, 3b and 3c is transmitted from a main control part, the picture display control part reads a sprite picture according to the command to edit picture data for display, and changes the R, G and B values of respective pixels in a region 60 specified by the dots A, B, C and D to values required for making corresponding pixels on a liquid crystal panel transparent respectively.
