    Abstract: PROBLEM TO BE SOLVED: To provide an image reading apparatus capable of turning on a lamp, which is bad in the dark startability, without increasing an equipment cost, and to provide its control method.
    SOLUTION: The apparatus includes a reflective original lamp used as a light source for irradiating the surface of a reflective original with light, a carriage which is mounted with the reflective original lamp and an image sensor, which detects and converts light into electric signals, and reciprocates in a sub-scanning direction, an indicator lamp that emits light to indicate the status of a device, and a decision unit which decides whether the reflective original lamp lights up by the use of the image sensor. When it is decided by the decision unit that the reflective original lamp does not light up, the carriage is moved to a prescribed position to enable the indicator lamp to irradiate the reflective original lamp with light.

    Abstract: PROBLEM TO BE SOLVED: To avoid the problem of vibrations without making the width of machine body large and to dispense with complicated arithmetic processing by performing magnification in the sub-scanning direction in the image reading of an image forming device, while using both a method for performing the magnification while changing the conventional moving speed of a carriage and a method for performing magnification through signal processing. SOLUTION: When a scale is smaller than a certain reduction factor at the time of reduction, the carriage moving speed is made about two times the setting factor. A line memory for one main scan line is provided inside an ASIC (1) 704 for a scanner, data for the first one line are stored, and at the time point when the next main scan line is fetched, after the averaging processing with the data of the first line is performed, they are outputted to an image processing ASIC (2) 705 on the following stage. In addition, filtering processing, gradation processing, binarizing, and main scanning direction magnification changing processing at the image processing ASIC (2) 705 on the following stage are performed as usual. The data processed by this image processing ASIC (2) 705 on the following stage are temporarily stored in a page memory(PM) 706.
