It is located inside.

The transparent plate member 35 may be made of transparent glass or, if desired, made of transparent plastic such as acrylic resin.

Preferably, the bottom wall 26, top wall 25, and side walls 27 are opaque, and the inner surfaces are finished with a non-reflective flat black background.

The sidewalls 28 are translucent, but may be made from a clear plastic material, or from polished glass, depending on the particular requirements discussed below. As can be seen in FIG. 2, the housing 11 includes a member 40 extending from the right side, and the lens housing 4
2, an outer housing 43, and a reel 44 provided at the top of the housing 43.
A strip projector 41 is carried on said member 40. Projector 41 functions to direct an image from a film strip (not shown) mounted on reel 44 through lens housing 42 onto side wall 28. Needless to say, at this time, the person in charge of projection is standing behind the projector. Said image passes through the side wall 28 and reaches the transparent plate member 35. The image on the transparent plate member 35 is reflected by a member with mirror properties due to the non-reflective black inner surface of the housing.

The image on the plate member 35 is visible to the performer or speaker in its correct form and is also used by a film strip projector 4 (not shown) to match the film strip to the performer's or speaker's lines.
It is also visible to the person in charge of operating the projector who controls the forward motion toward the projector.

Although the performer or the speaker can visually see the image on the transparent plate member 35, the image is prevented from affecting the image taken by the camera 10.

FIG. 3 illustrates another embodiment of the housing 111, which includes a top wall (not shown), a bottom wall 126, side walls 127, 128, and a rear portion of the housing 111. It includes a transparent member 135 extending diagonally toward the front.

The side wall 128 is semi-transparent and is similar to the side wall 2 of the housing 11.
This is similar to 8. The housing 111 includes a rear wall 129, which, unlike the fabric 29 of the housing 11, is illustrated as being of a rigid configuration. The rear wall 129 includes a hole 130 into which a camera lens housing 117 protrudes from a camera (not shown). The inside of the housing 111 is finished with a non-reflective flat black surface, as described for the housing 11. 4 and 5, which show the housing 111 of FIG. 3 from different directions, the roll 15
0.151 is rotatably attached to the side wall 128 using a bracket 152 and carries a transparent film 155, such as acetate.
