CONSTITUTION: A sheet guide of a sheet shutter comprises a sheet case, pillars(3), a sheet guide part(11), an outer rail(14), and an inner rail. A sheet drum for rolling and unrolling a sheet(2) is horizontally supported in the sheet case. The pillars support both right and left ends of the sheet case. The sheet guide part is fixed to the pillars and guides the ascent and descent of the sheet. The outer rail has a U-shaped cross section and includes a pair of side walls. The inner rail is removably installed inside the outer rail and includes a coupling guide(21) which receives guide protrusions(10) of the sheet to ascend and descend.
