ABSTRACT:
An image scanner has a reflecting mirror for reflecting a light beam from an original, a one-dimensional image sensor for scanning the original in a main scanning direction with the reflected light beam from the reflecting mirror to produce a partial image of the original, and an auxiliary scanning mechanism for angularly moving the reflecting mirror to cause the reflected light to scan the original in an auxiliary scanning direction transverse to the main scanning direction, thereby to enable the one-dimensional image sensor to produce in main scanning cycles respective partial images of the original which may be combined into a two-dimensional image of the original. An image converter converts the partial images depending on changes in an optical path length from the original to the one-dimensional image sensor. The image scanner thus constructed is relatively small in size and simple in structure, prevents produced two-dimensional images from being distorted, and is capable of reading images at high speed.
