摘要： An automatic screen for projecting an image from a video projector onto it is disclosed. It has a cabinet 1 which accommodates a screen 2. The screen 2 can be moved relative to the cabinet by a chain 5a coupling a front door 1a of the cabinet 1 and a sprocket. The front door 1a of the cabinet 1 is opened in an interlocked relation to the operation of bringing the screen 2 to a set position projected from the cabinet 1. When the screen 2 is no longer used, it can be brought back into the cabinet 1, and in an interlocked relation to this motion the front door 1a of the cabinet 1 is closed.

摘要： An image projecting unit is shown which comprises a structure having a display surface on which a visual image is displayed, and a lens assembly movably arranged in front of the display surface of the structure. The lens assembly has a rearmost lens which faces the display surface. A bellows is disposed between the display surface and the rearmost lens to define therebetween a sealed space, and a liquid is contained in the sealed space to optically connect the display surface and the rearmost lens.

摘要： The present invention provides a reflex-type screen which is wound up by a winding shaft to be retracted and is unwound from the winding shaft in use. The reflex-type screen comprises a reflection layer which reflects an incident light, a transparent surface protective layer provided on a first surface of the reflection layer, and a back surface protective layer provided on a second surface of the reflection layer, wherein as between the surface protective layer and the back surface protective layer, the one that has a higher loop stiffness value, faces inward when the reflex-type screen is wound up by the shaft.

摘要： A cathode ray tube device employed in a projection apparatus for projecting an image on a screen. The cathode ray tube device includes a supporting frame mounted on a rim of a front panel section of the cathode ray tube, a lens plate in the form of a frame having a center aperture, and having a projection lens system attached to it, and a positioning supporting member detachably mounted on a mounting base plate of the projection apparatus and adapted for positioning the supporting frame and the lens plate with respect to the mounting base plate for detachably supporting the supporting frame and the lens plate by the mounting base plate. The positioning supporting member has a lens plate supporting surface for supporting the lens plate at a tilt angle corresponding to a convergence angle with respect to the mounting base plate and a supporting frame supporting surface for positioning and supporting the supporting frame at a tilt angle corresponding to an elevation with respect to the lens plate and at a distance corresponding to a back focal length at back of the lens plate for accurately setting the convergence angle, elevation and the back focal length.
