Abstract
A figure defining system (39, 43, 46, 57) defines a first figure as a pointer (43) on a background plate (39) and a second figure as a character plate (46) with characters and divisions, a figure illuminating system (39a, 43a, 47, 49, 55a, 51, 53) includes a rear light transmitting plate (47) for illuminating the pointer (43) as a figure element of the first figure to be visible, the rear light transmitting plate extending along a first plane, a top light transmitting plate (49) for illuminating the characters and divisions as figure elements of the second figure to be visible, the second light transmitting plate extending along a second plane crossing the first plane, and a common light source (51) disposed in a corner chamber partially defined by an end face of the rear light transmitting plate and an end face of the top light transmitting plate, and a half mirror (41) arranged between the first and second planes for displaying a combination of an optical image of the first figure, as it is transmitted through the half mirror, and an optical image of the second figure, as it is reflected on the half mirror, to have images of the figure elements combined to be visible in a display field.
