Abstract: A multi-purpose table with embedded metal nuts for assembly includes two vertical support plates, a top plate and a horizontal plate assembly. The vertical support plates and the top plate are made hollow and formed of plastic material by way of blow molding. The vertical support plates are substantially parallel with and opposite to each other. The top plate, on which an electronic apparatus is to be placed, is connected to the vertical support plates. The horizontal plate assembly is connected to the vertical support plates, wherein the top plate and the horizontal plate assembly are connected to the vertical support plates through a plurality of screws screwing into a plurality of metal nuts embedded in the vertical support plates.

Abstract: A light source for scanning a transparent film is equipped with a light intensity adjustment plate inserted between a light reflector and a light slot. The light intensity adjustment plate is partially painted to absorb light, so that the stronger light from the parallel center section of a linear light is weakened to produce a more uniform light along the whole scanning length.The light intensity adjustment plate can be placed between the U-shaped light tube, or attached to the inner wall of the U-shaped light tube housing. The light intensity adjustment plate can have a frame which is rectangular or concave. The light intensity adjustment plate can also have an shaped extension toward the light tube to produce more uniform light.
