Scope

This standard specifies the size of the screen area of the projection table, the position of the positioning pin, the size and the size of the flat area, and the position of the support rod of the projection head of the A-type (250 mm×250 mm) and B-type (285 mm×285 mm) transmissive projectors. , the notable difference between the two tabletop projectors is the size of the picture area. This standard applies to Type A (250mm×250mm) and Type B (285mm×285mm) transmissive projectors. This standard is compatible with two tabletop projectors and their transparencies, and does not apply to projectors for other special purposes, excluding special equipment such as radiographic projection.
