    Abstract: An image reading device reads a document using a plurality of reading modes including a sheet-through reading mode for reading a document at a fixed reading position while the document is automatically fed. The image reading device includes a first resolution changing means, a second resolution changing means, and a resolution setting means. The first changing means changes one of a linear velocity at which the document is fed and a traveling speed of a reading carriage to change a resolution at which the document is read in a sub-scanning direction. The second changing means electrically interpolates image data output from the first changing means to change a resolution of the image data. The resolution setting means provides a plurality of combinations of resolution change rates between the first and second changing means as resolution change modes and sets the first and second changing means to one of the combinations.

    Abstract: PROBLEM TO BE SOLVED: To solve the problem that a beam light scanner and an image forming apparatus using the scanner become expensive, when a large number of the laser diodes are used, since a laser diode which emits light beams is expensive.
    SOLUTION: A beam light scanner comprises: an image data processing section 31 which sorts adjacent pixel data that are image processed into first and second pixel data and outputs them; a synchronizing circuit 32 which outputs the first and the second pixel data in synchronism with the clocks that are synchronized on the basis of horizontal synchronization signals BD; PWMs 35 and 36 which adjust the pulse widths of the first and the second pixel data outputted from the synchronizing circuit 32; a composition circuit 40 which composites the first and the second pixel data whose pulse widths are adjusted; and a laser diode 81 which emits light beams after composition. Consequently, light emission is conducted at high speed for image forming by a smaller number of light emitting means and the beam optical scanner and the image forming device costs of which are suppressed are obtained.

    Abstract: PROBLEM TO BE SOLVED: To enable reading at high speed as much as possible with a simple configuration in an image reading apparatus including a sheet feeding device. SOLUTION: The image reading apparatus determines whether an amount of image data read from an original which is stored in a buffer, exceeds a predetermined first threshold or not. When the amount of the image data exceeds the first threshold, the image reading apparatus decelerates original transport and stops it, and in a deceleration period of the original transport, the image reading apparatus accelerates a carriage in a direction reverse to the original transport direction, and continuously from before the start of the deceleration period, reads the original in the deceleration period.
