PURPOSE:To enable monitor of plural pieces of information simultaneously without imposing the burden on an operator by constituting a titled device so that the 1st and the 2nd picture display devices and a half mirror recognize picture light of both devices in the same direction as transmitted and reflected light. CONSTITUTION:The 1st CRT display device 2, the 2nd CRT display device 2 and half mirror 4 are arranged so that a picture display face 2a of the 1st CRT display device 2 and the 1st vertical axis line 5, a picture display face 3a of the 2nd CRT display device 3, the 2nd vertical axis line 6, the half mirror 4 and the 3rd vertical axis line 7 will be positioned in the same horizontal plane. Moreover the 1st and the 2nd CRT display devices 2 and 3 are arranged so that a distance L1 from said face 2a of said device 2 to the half mirror 4 and L2 from said face 3a of the 2nd display device 3 to the half mirror 4 will be different from each other. Thus eyes E can recognize simultaneously picture light of the device 2 and that of the device 3.
