ABSTRACT:
A luminous apparatus capable of adjusting the luminance is equipped in a scanner. Before mounting the luminous apparatus in the scanner, a detective device is used for detecting luminance generated from the luminous apparatus. The luminous apparatus contains the electroluminescent elements, the branching levers, and the main lever. One end of each electroluminescent element is pivoted by a pivot while the other end is connected to one branching lever correspondingly. The main lever is connected to those branching levers. When the main lever is moved by an external force, the branching levers are moved and the electroluminescent elements synchronous rotate around their own pivots. Additionally, the positions of the main lever and the electroluminescent elements are fixed when a uniform luminance is detected.
