The present invention relates to a lightbox having an ergonomic structure which comprises: a polygonal main body; a backlight module that is installed in the center of the main body; a drawing board that is installed above the main body and made of a material that transmits light; magnet holding grooves that are formed outside the backlight module, and on the upper and lower ends of or on the left and right sides of the periphery of the main body; and plate-shaped magnets that are held in the magnet holding grooves, wherein the magnets are covered with the periphery of the drawing board in order not to be displaced out of the inside of the magnet holding grooves while at least two fixing metallic plates laid on the drawing board press down a drawing printed sheet and tracing paper tightly on the drawing board with magnetic force of the magnets. The present invention enables the very thin fixing metallic plates to adhere to the drawing board by means of the magnets embedded in the main body, thereby firmly fixing the drawing printed sheet and the tracing paper keeping the sheet and the paper from dropping down, and, at the same time, minimizes a protrusion from the drawing board so that hand movements for drawing are not obstructed by the protrusion. In addition, the main body according to the present invention has inclined supports beneath the bottom of the main body to make the main body inclined when the main body is used and provide the ergonomic structure. Moreover, the main body is capable of being equipped with a lamp and a book stopper so that the present invention can be used as a bookstand. |
