摘要： An outer suspension type lens shielding mask for a projection apparatus including a sheet body and holding element, in which a rectangular hole is opened in the sheet body, and the sheet body is combined with the holding element to be fixed on a projection apparatus. Another outer suspension type lens shielding mask includes a base plate, in which a rectangular hole is opened in the middle part thereof, and upper and lower adjustable plates are installed behind the base plate. An open rectangular notch is respectively disposed at the middle parts of the upper and the lower adjustable plates. An adjustment mechanism includes a plurality of connecting elements connected to the base plate and the upper and the lower adjustable plates for adjusting the relative positions thereof, to avoid bad shadows yielded outside of a picture due to light diffraction and improve the quality of visual amusement.

摘要： An outer suspension type lens shielding mask for a projection apparatus according to the present invention comprises a sheet body and a holding element, in which a rectangular hole is opened in the sheet body and the sheet body is combined with the holding element together for being fixed on a projection apparatus. Another outer suspension type lens shielding mask according to the present invention comprises abase plate, in which a rectangular hole is opened in the middle part thereof, upper and lower adjustable plates, installed behind the base plate and an open rectangular notch is respectively disposed at the middle parts of the upper and the lower adjustable plates, and an adjustment mechanism, consisting a plurality of connecting elements connected to the base plate and the upper and the lower adjustable plates for adjusting the relative positions of the upper and the lower adjustable plates on the base plate. Whereby, bad shadow yielded at an area outside of a picture due to diffraction light can be avoided and the quality of sight amusement can be improved.
