<p>PURPOSE:To always omit the necessity for scroll together with elimination of the vertical/horizontal synchronizing deviation and also to improve the operability of an electronic equipment by providing >=2 display devices to secure the common vertical/horizontal synchronization as well as the mechanical interlock among those display devices and at the same time setting an optical axis at an imaginary point. CONSTITUTION:At least two display devices 11 and 12 or more are provided into an equipment case 10. Then the common vertical/horizontal synchronization and the mechanical interlock are secured between both devices 11 and 12. At the same time, an optical axis is set at an imaginary point. Thus the constant scroll is not required even if a document or a command message contains many items. In addition, the vertical/horizontal synchronizing deviation can be eliminated when both devices 11 and 12 are moved. Then the fatigue of an operator can be reduced and no problem is produced even though the operator's eyes are always kept at the same position. Thus the operating efficiency is improved for an electronic equipment.</p> |
