Dome screen, dome screen projection apparatus, and method for fabricating the same

A dome screen projection apparatus, comprising a dome screen and a frame holding the screen, wherein the screen is formed by joining plural screen members made of a synthetic resin, the frame is formed by plural components and holds the curved screen in a suspended condition;

• and a projector for projecting an image on an inner face of the dome screen.

A method for producing a dome screen, comprising:

• installing a basal member of a frame on a base site, standing plural fabrication column members on the basal member, attaching a lifting member to the column member, fixing a beam member to the lifting member, raising the beam member to an intermediate portion of the column member by the lifting member, joining curved screen members of a screen upper portion, suspending the joined screen members from the beam member, further raising the beam member to an upper portion of the column member, joining screen members of a screen lower portion to the joined screen upper portion to integrate them into a dome screen, and holding the dome screen in a suspended condition by the frame.

A method for fabricating a dome screen projection apparatus, comprising:

• installing a basal member of a frame on a base site, standing plural joint-type column members on the basal member, attaching a lifting member to the column member, fixing a beam member to the lifting member, setting a projector on the beam member, raising the beam member to an intermediate portion of the column member by the lifting member, joining curved screen members of a screen upper portion, suspending the joined screen members from the beam member, further raising the beam member to an upper portion of the column member, joining screen members of a screen lower portion to the joined screen upper portion to integrate them into a dome screen, and holding the dome screen in a suspended condition by the frame.
