Abstract
PURPOSE:To enable to switch CRT display devices to which a light pen is connected, by instructing a specific part on the CRT displays in instructing a plurality of CRT display devices with the light pen from the operator. CONSTITUTION:A plurality of CRT display devices 1a and 1b are provided with selecting parts 5 and 6 for light pen switching designation for the number of CRT display devices. When a light pen 3 instructs the selecting part 5 for the CRT display device 1a or 1b, the light pen 3 is connected to the CRT display device 1a with a connector for light pen switching, and when the part 6 is instructed, the light pen 3 is connected to the CRT display device 1b.
