摘要

A panoramic shooting target scene is optically created on a screen by having two paper sheets 1,2. The sheets have an amount of overlap that is adjusted to generate a required visual effect. The overlap amount is of the order 5 to 15 cm. The lower edges of the sheets are passed around a number of rollers 3-6. and the assembly may be raised and lowered between two reference positions. This operation does also provide a tilting. This action results in relative movement of the sheets, which has an automatic drive control.
