    摘要： A picture reader is provided with a read unit (2) equipped with a contacting member (21) which comes into contact with an original placing table (11) of a flat bed unit (1) and a pressing element (30) which presses the unit (2) against the table (11). Another picture reader is composed of a reader main body (50) having a read unit (102) and an original placing table (51), and an original cover (42) which has a light source (43) and a diffusing plate (45) and is attached to the main body (50) is an openable state, the distance to the light source (43) from a transparent original (41) placed on the table (51) being variable correspondingly to the thickness of the original (41). A still another picture reader reads in advance the accumulated difference between the movement of the optical unit (102) and a light source unit (43) and, when read scanning is started, shifts the relative position of the optical unit (102) to the light source unit (44) in the direction in which the accumulated difference is produced.

    摘要： An image reader comprises a lens unit 4 having a lens 1 of low resolution, a lens of high resolution, and a first drive unit 3 for driving the lenses and a second drive unit 5 for driving the lens unit 4. In a first resolution mode, the lens 1 of low resolution is placed in a first position along the optical axis, and the lens 2 of high resolution is not placed in a position along the optical axis. In a second resolution mode the resolution of which is higher than the first resolution, the lens 1 of low resolution is not placed in a position along the optical axis, and the lens 2 of high resolution is placed in a second position along the optical axis. In a third resolution mode the third resolution of which is higher than the second resolution, the lens 1 of low resolution is not placed in a position along the optical axis, and the lens 2 of high resolution is placed in a third position along the optical axis.

    摘要： An original reader such as an image scanner for inputting image information, provided with a light source for illuminating an original, a lens unit (8) capable of optically changing resolution, and a solid-state image sensor substrate placed on an image forming plane (10) of the lens, wherein the lens unit (8) includes a plurality of lenses that can deal with a plurality of different resolutions and one lens corresponding to a specified resolution is selectively moved into a light path. The lens unit and the solid-state image sensor substrate are independently movable in the direction of optical axis for focusing.
