This visual inspection apparatus has a macro-inspection section and a micro-inspection section. In the micro-inspection section, a inspection stage and a microscope are loaded into a loading plate. The inspection stage can be moved in any directions of the X, Y, and Z directions, and can also be rotated in the &#x3b8; direction. Moreover, a peripheral edge inspection section that acquires an enlarged image of a peripheral edge of wafer W is fixed to the loading plate. The peripheral edge inspection section is arranged so as to image the peripheral edge of wafer W held by the inspection stage.

Visual inspection apparatus, visual inspection method, and peripheral edge inspection unit that can be mounted on visual inspection apparatus

A table type display device, in which a high resolution display with an unremarkable connection is realized at the time of large screen display by using a screen with a composition having few bending is described. In a table type display device comprising plural M of projectorsL,R for projecting luminous flux to form an image, plural N of reflection mirrorsL,R for bending optical paths of luminous fluxes projected from respective plural M of projectorsL,R, screenof horizontal installation type for projecting luminous fluxes for which optical path is bent, by the plurality N of reflection mirrorsL,R onto the predetermined region, respectively, the screen comprises a transparent base memberfor reducing flexure of the screen, optical sheetsubstantially for making luminous fluxes projected respectively from the plural M of projectorsL,R uniform, and a diffusing screen for imaging the image.

Table type display device

A table type display device capable of selecting the best projector according to user's budget and mode is provided for with easy exchange of the projector. The table type display device comprises four projectorsLU,LL,RU, andRL for projecting luminous flux to form image, reflection mirrorsU andL for bending an optical path of luminance flux projected from each of these projectors, and a screenof horizontal installation type for projecting luminous flux with its optical path being bent by reflection mirrorsU andL, onto predetermined regions respectively. The screen housing portionof the main body unitaccommodates the screen, the reflection mirrorsU andL, and the light shading platesLU,LL,RU, andRL, and the projector unit housing portionof the main body unitaccommodates projectorsLU,LL,RU, andRL housed by the projector unit
