PURPOSE:To reduce an installation space and to simplify control by arranging a high density image display device having a compact size in the front of a low density image display device and controlling respective display devices by corresponding control means. CONSTITUTION:The compact size high density image display means 4 controlled by the high density control means 2 and a high density image display device for displaying residual characters on a translucent area are arranged in the front of the low density image display means 3 controlled by the low density image display control means 1. In this constitution, the installation space of the high density and low density image display devices can be reduced, and since respective display parts are controlled by individual control means, the control can be simplified and the economic efficiency of the device can be improved. |
