发明名称 TRANSMISSION SCREEN
摘要 PROBLEM TO BE SOLVED: To provide a transmission screen having high impact resistance against repeated impacts such as when the screen is attached or detached in a rental multiscreen projection imaging device. SOLUTION: This screen is equipped with a screen member consisting of a plurality of sheet members where a magnified and projected optical image from an image source is transmitted (e.g. a member consisting of a lenticular lens sheet 5 and a Fresnel lens sheet 6), a light shielding body 3 attached to the end part of at least one sheet member (e.g. the lenticular lens sheet 5) of the plurality of sheet members to tightly adhere the plurality of sheet members when tension is added, and a tensile mechanism 2 to add the tension on the light-shielding body 3, and a supporting member 1 to which the tensile mechanism 2 is fixed. The sheet member (e.g. the Fresnel lens sheet 6) to which the light-shielding body 3 is not attached of the plurality of sheet members is fixed to the supporting member 1 with a tape 9 or the like.
