Abstract: A game machine controller with keys controls the movement of an image subject displayed on a monitor screen in an X- and a Y-axis direction. A first and a second controller section are coupled to each other by a coupling member. Relative displacement information of the first and second controller sections with respect to the coupling member is detected. The movement of the image subject in a Z-axis direction is controlled based on the detected displacement information.
