    摘要: A mechanism for and a method of controlling the lens position in an image scanner in which the density of read lines can be varied by selecting one of lens. A base is rotatably provided in a plane parallel to a table on which an original is placed. The lens is supported on the base in such a way that the optical axis of each lens is parallel to the base surface and intersects the rotation axis. A reference pattern is provided at a place where an image receiving device can read it through the lens. On the basis of the received image of the reference pattern, the lens in the optical path is identified, and its position is determined. The rotation of the base is thus controlled to set an appropriate lens in an appropriate position. In such a way, an image scanner such that the lens can be changed in a high precision is provided without increasing the height.

    摘要: The original documents of A4 or A3 format are selectively read by a scanning apparatus (2) which is integrated into a system for producing and transmitting images. The originals of A4 format are normally positioned on a fixed exposure surface (5) and the originals of A3 format are introduced into a separate device (7) for transporting documents, which is adjacent to the fixed exposure surface (5). A carriage (22) with lamps (36) is slidable below the exposure surface (5) to illuminate the A4 original while to illuminate the A3 original the carriage (22) is moved into a fixed position (23) corresponding to the separate reading device (7) where the original A3 is slid with respect to the carriage past an exposure zone (E). The reflected images of the originals are passed by means of mirrors (40,42,44) mounted on the carriage (22) to a lens (45) which reflects them on to a photodetector device which converts the light rays into digital electrical signals. To adjust the focal lengths of the lens (45) to the various dimensions of the A3 and A4 formats and to compensate for the different distances (difference D) of the two types of originals from the lens, two of the mirrors (42,44) are mounted on an auxiliary frame which is movable on the carriage. The auxiliary frame is displaced by its own motor (76) and a lead-screw (70) to different positions in relation to the type of original which is to be read.

    摘要: An image scanning apparatus includes an illuminator to radiate light on an original image; an image sensor to scan image information of the original image from the light reflected from the original image, an image processor to perform image processing with respect to a signal scanned by the image sensor, and a memory to store data which is to be image-processed. The image sensor, the image processor, and the memory may also be disposed on one circuit board in the image scanning apparatus.
