  • Patent number: 9094563
    Abstract: A reading unit (3) placed on the inner side of a U-shaped feed path (12) that feeds a document is formed such that the height-axis dimension of said reading unit decreases in a direction extending toward a side having a paper delivery tray (11). Contact glass (20), a light source and a first mirror (24) are placed in the reading unit (3) at an end portion of the side having the paper delivery tray (11). Multiple reflecting mirrors (25, 26 and 27), a lens (28) and a photoelectric converter element (29) are placed further from the paper delivery tray than the first mirror (24) in the reading unit. This structure enables the reading unit provided in a document feeder to be more compact while ensuring the required light path length, and enables the entire document feeder to be more compact.

  • Patent number: 8830541
    Abstract: An apparatus is provided capable of guiding regular reflected light from a reading surface to a reflecting mirror when light is irradiated from two directions from light sources to the reading surface, and is suitable to read a gloss image. The light sources for irradiating light to the reading surface from the two directions of different angles are configured of a first light emitter and a second light emitter, a mirror reflecting surface for specularly reflecting light and a translucent surface for passing light therethrough being formed on the surface of a reflecting member for deflecting light from the reading surface to a predetermined reading light path direction, the first light emitter being arranged between the platen and the platen side surface of the reflecting member, the second light emitter being arranged at the back surface of the reflecting member so as to irradiate light on the reading surface through the translucent surface.
