<P>PROBLEM TO BE SOLVED: To provide a game machine including a video device capable of supplying video images to be excellently viewed by a player on a screen. <P>SOLUTION: The game machine includes the video device capable of displaying a prescribed video image by supplying a luminous flux from a video projection means (41) from the back surface side of a screen (23) provided so as to face front surface glass (11). The video projection means (41) includes: a light source for supplying the luminous flux; a luminous flux path change means (43) for directing the luminous flux from the light source toward a direction at an angle from a vertical direction with respect to the main surface of the screen; an image forming means (44) for guiding the luminous flux which has passed through the luminous flux path change means (43) to the screen (23); and a modulation means inside an optical path between the light source and the luminous flux path change means (43), for supplying optical modulation to the luminous flux. The game machine further includes an image signal formation part for sending out image signals to the modulation means and an image signal correction part for performing trapezoidal correction on the image signals. <P>COPYRIGHT: (C)2012,JPO&INPIT |
