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.

摘要： According to one embodiment, a document detecting apparatus includes a light-emitting element, a photoelectric conversion element, a light-emission controller and a detection processor. The light-emitting element projects light onto a detection position of a document. The light-emitting element is not used for reading an image of the document. The photoelectric conversion element converts light projected onto the detection position into an electric signal and outputs the electric signal. The light-emission controller changes the light quantity of the light emitted by the light-emitting element during a predetermined interval. The detection processor detects the presence or absence of the document at the detection position of the document based on whether a value of the output electric signal during the predetermined interval changes in correspondence to the change of the light quantity caused by the light-emission controller.

摘要： A multicolor image forming apparatus is provided which is capable of suppressing rotational vibrations caused by a rotary unit thereby to carry out the formation of images of excellent quality even if the amount of remaining toner in the rotary unit changes. In the multicolor image forming apparatus (10), accelerations, uniform speeds and decelerations, which do not cause residual vibration of the rotary unit due to overshooting when the rotary unit (11) is changed from its acceleration rotation to its uniform rotation or vice versa, are stored in an acceleration and acceleration storage section (16) in correspondence to the amounts of toners held by the developing units. A rotary unit rotation control section (17) detects the amounts of remaining toners of the developing units through a toner amount detection section at each timing when the rotary unit is driven to rotate for development, reads out an acceleration, a uniform speed and a deceleration corresponding to the detected amounts of remaining toners from the acceleration and deceleration storage section, and controls the rotational movement of the rotary unit according to the result thus read out. Accordingly, the rotary unit does not generate residual vibration upon switching of its rotation.

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.
