摘要： An image forming apparatus in the present invention includes an automatic document feeder (ADF) for carrying an original document, a scanner unit and a printer unit, the scanner unit includes a carriage having a light source unit for exposing and scanning the original document and is capable of operating in a first reading mode (sheet-through system) for reading image information of the original document carried by the ADF with the carriage fixed and a second reading mode (platen system) for reading the image information of the original document by moving the carriage. When reading the original document, the scanning velocity is controlled, the reading resolution of the original document in the first reading mode is set to be lower than the resolution of image formation by the printer unit, and the reading resolution of the original document in the second reading mode is controlled to be substantially equal to the resolution of image formation by the printer unit. There is provided an image processing unit for performing image conversion for the image information read by the scanner unit according to the reading magnification.

摘要： Where a magnification (enlargement/reduction of image) has been set through operation keys of an operation panel, a main CPU sends information on read magnification to a scanner CPU of a scanner section. In this case, where the magnification is not set in particular, information of 100% magnification is sent to the scanner CPU. Based on a microstep division number of a step angle corresponding to the received information on read magnification, the scanner CPU controls the driving of a scan motor via a scan motor driver.

摘要： An image reader of the present invention comprises a fluctuation detector that can be connected to the external equipment by means of an image data input-output section, and can subject image data, continuous in a first direction and outputted as image information on a test chart is photoelectrically converted by means of a CCD sensor when a mirror set or the test chart is moved in the first direction, to Fourier conversion, thereby obtaining the frequency of a fluctuation of the obtained image data and a maximum value of the amplitude thereof. If the obtained maximum value of the fluctuation amplitude is greater than a given value, the fluctuation detector is used to compare the frequency of the fluctuation and the natural frequency of a drive motor for generating driving force for moving the mirror set or the image. If the fluctuation frequency and the natural frequency are not equal, the value of current supplied to the drive motor is increased.
