Claims

[Scope of utility model registration request]

(1) When the holding cover for the projection material on the stage surface is opened, the tip of the lever that is interlocked with the shutter is released from the holding cover and rises to the outside through the hole in the main body, so that the shutter blocks the light source from the stage surface; When the presser cover is closed, the lever is pressed by the presser cover and lowers into the main body, and the shutter retreats from the light source so that the light source illuminates the stage.

(2) A physical projector according to claim 1, which uses a metal halide lamp as a light source.

(3) A physical projector according to claim (1) of the utility model registration, wherein an appropriate number of small holes are provided in the shutter plate of the shutter.
