Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is based on and claims priority under 35 USC 119 from Japanese Patent Application No. 2023-012712 filed on Jan. 31, 2023 and Japanese Patent Application No. 2024-009863 filed on Jan. 26, 2024, the contents of which are incorporated herein by reference. FIELD The present disclosure relates to a screen unit, a method for assembling a screen unit, and a method for disassembling a screen unit. BACKGROUND JP2022-128611A discloses a video device including a projector, a screen, and a holder for mounting the screen. The screen in JP2022-128611A includes a magnet sheet attached to a back surface of the screen. The holder is formed by providing and joining a plurality of partition plates via a joint. The partition plate includes a portion for adhering to the magnet sheet. The video device includes a screen flattening unit that flattens the unevenness of the magnet sheet caused by a step and/or a gap at the joint of the partition plate. JP2008-040153A discloses a roll-type screen subjected to aluminum vapor deposition.
