Abstract

PURPOSE: To obtain the screen device which is convenient to carry and is difficult to damage by constituting the device by a frame body formed with the slit holes or slit grooves having the specified curvature on the top, bottom, right and left surfaces and a flexible screen.
CONSTITUTION: Slit holes or slit grooves 2, 3, 4, 4 having the specified curvature are formed on the top, bottom, right and left surfaces of a frame body 1 made of wood which is assembled by four sheets of plates and which is open at the front. A screen 5 comprising affixing an aluminum foil on a flexible flat plate such as aluminum or iron plate is assembled to the frame body 1 by inserting the same through the slit hole 2 at the top surface of said body as shown by the arrows. In this way, the assembling is easy and since this may be disassembled to the four plates of the frame body and the screen at the packing and transporting, its carrying becomes easy and the danger of damaging the screen may be reduced.
