PURPOSE: To enable arousing of interests in a display pattern with the specifying of a display mode of the pattern by forming a screen part on a transparent plate arranged in parallel in front of a game board to project a pattern image enlarged of an original pattern image displayed on a pattern display body. CONSTITUTION: A transparent window plate 3 integral with a window frame 2 is arranged with an opening part 1a of a game board 1 while a pattern display body (liquid crystal display) 6 which is capable of displaying patterns in variation to control a variation display mode of the patterns with a controller 5 is set at a lower part in a frame 4 bonded to the window frame 2. A mirror 8 is set behind the window plate 3 above the pattern display body 6 to reflect a luminous flux 10 of the original pattern image, irradiated by a light source 7 and then, projected upward, forward in such a manner as to be allowed to oscillate being inclined. Then, the mirror 8 is made to oscillate in repeated reciprocation with the operation of a motor 17. This allows vertical reciprocation of the luminous flux 10 of the original pattern image thereby achieving a projecting of an enlarged image on the screen part 16. |
