摘要： A reading scan controlling unit drives a scanning motor in accordance with a signal from a reading instructing unit and a line synchronous generating unit for scanning a document plural times in a slow-scanning direction, as well as controls a sensor driver to read a document image. At this time, an optical flat plate driving unit is controlled in the second and following scans to incline an optical flat plate provided in an imaging optical path at a predetermined angle in a fast-scanning direction, so that the imaging position on a CCD sensor in a fast-scanning direction is slightly changed. Further, the scanning speed is determined in accordance with the scanning times. An image reading device having such a construction can perform high-speed reading with high precision by using an image shift method.

摘要： An image sensor includes a plurality of photosensitive pixel lines adjacent to each other in the sub-scanning direction, each of the photosensitive pixel lines having a number of photosensitive pixels arranged in the main scanning direction, and horizontal transfer registers disposed outside of the photosensitive pixel lines. A storage part for saving therein signal charges on a pixel-by-pixel basis is interposed between the photosensitive pixel lines and the horizontal transfer registers. Transfer of signal charges between the photosensitive pixel lines, storage part, and horizontal transfer registers are controlled by operating shift gates so that at a time point when exposure of the inside photosensitive pixel line has been finished, signal charges of the outside photosensitive pixel line is saved into the storage part to thereby secure a transfer passage for signal charges of the inside photosensitive pixel line.

摘要： The image reading device of the present invention reads images by using a visible light and an invisible light that are generated by a single light source. The fluorescent lamp is provided with a pair of internal electrodes and a pair of external electrodes. It generates a visible light with a higher intensity than an infrared light when switching a feeder circuit on to generate a discharge between the external electrodes. On the other hand, it generates an infrared light with a higher intensity than a visible light when switching another feeder circuit on to generate a discharge between the internal electrodes. Therefore, the fluorescent lamp has a reading mode using the visible light, and a reading mode using the infrared light. And, a lamp controller selectively switches the emission mode of the fluorescent lamp.
