Facsimile device with a white level controller

An apparatus for facsimile having glass means for supporting a document to be read, and guide plate means for guiding said document to said glass means, said apparatus comprising:

• reading means positioned adjacent to said glass means for reading said document when said document has been fed to said glass means;
• and
• white level controller means adjacent said glass means, said white level controller means having a white reflection surface for providing a white level indicative of a white level of said document, said white reflection surface being read by said reading means through said glass means prior to said document being fed to said glass means,
• said white level controller comprising first and second support means for maintaining said white reflection surface with a non-rotating orientation toward said glass means, said first and second support means having guide grooves and a guide member coupled to said first and second support means, said guide member having first and second guide means respectively engaged with said guide grooves of said first and second support means to enable said guide member to be movable, a first bottom portion and a second bottom portion of said guide member being in contact with said glass means due to said guide member's own weight, said first and second bottom portions being positioned apart from each other by an area defined by said white reflection surface.

A facsimile device comprising:

• a reading device for reading a source document;
• a glass plate disposed above said reading means;
• a white level controller located above an upper portion of said glass plate, said white level controller being of semicylindrical shape having a white reflection curved surface disposed next to said glass plate for providing a white level indicative of a white level of the source document when read by said reading device, and a groove located along a flat surface thereof for receiving a weight;
• and
• support means comprising guide grooves and a guide member coupled to said guide grooves, said guide member having triangular shaped guide tabs engaged with said guide grooves to enable said guide member to be movable up and down, said guide member being constructively combined with said white level controller to enable a portion of said white reflection curved surface to contact said glass plate.
