To display stereoscopic images without putting the burdens of an image processing.

A game machine comprises: an image information storage part 240 for storing the virtual reel data of the generation origin of images indicating a display area to be displayed at an image display device 300 and the image data of the generation origin of the images indicating two or more pieces of identification information to be successively displayed in the display area; a control data storage part 250 for storing magnification change data for increasing horizontal and vertical direction components with respect to the relatively changing direction of the image data and restoring the respective increased components when a change amount exceeds a threshold when relatively changing the components in one direction of two dimensions that the virtual reel data and the image data have, and for storing timing data for specifying a timing of outputting a trigger signal from a timing means 230; and an image generation means 220 for generating the images to be displayed at the image display device 300 on the basis of the image data and the trigger signal. The image generation means 220 generates the images to be displayed at the image display device 300 on the basis of the magnification change data, the image data and the trigger signal.
