发明名称 Optical toy device and method of manufacturing thereof
摘要 In an optical toy device and a method of manufacturing the same, a frame for eyeglasses is cutout of a blank which is provided with two pairs of holes aligned with each other and is coated with a vinyl material on a side thereof. Adhesive is applied to the reverse side of the blank, and two feathers are attached to its reverse side to overlap two holes on one half of the blank and form with the holes eyepiece lenses. The blank is folded at its backside together so that its halves are glued to each other. The frame having two eyepiece lenses are formed thereby. A temple bar folded to form thereon two hinges is heat-sealed to the frame. The feathers are attached to the frame in such fashion that the barbs of the feather overlapping one hole for one eyepiece are angularly oriented with the barbs of the feather overlapping another hole for the other eyepiece to produce an X-ray image of an object to be viewed.
