摘要： A motor comprising: a rotor which is supported via a rotating shaft in a radial direction of the rotating shaft, the rotating shaft being disposed around a fixed shaft provided on the side of a stator to form a dynamic-pressure bearing; a stator-side thrust magnet disposed in the stator so as to support the rotor with respect to the stator in a thrust direction of the rotating shaft; a rotor-side thrust magnet disposed in the rotor; and a rotating main body portion mounted to the rotating shaft of the rotor and formed integrally by a resin magnetic material, in which a main magnet portion, an FG magnet portion for generating a speed-of-rotation detecting pulse, and a rotor-side thrust magnet portion serving as said rotor-side thrust magnet are respectively polarized at predetermined positions in the rotating main body portion. As a result, the reliability of an optical deflector in which the motor is used improves and the number of parts and the number of assembling processes are both reduced due to a simple structure. Further, a balance correction operation of the rotor is eliminated so as to allow a simple manufacturing operation, and even when the rotor is rotated at high speed, a stable optical scanning operation can be effected.

摘要： An exposure device includes plural light-emitting elements, a light amount detection unit, a controller, plural holding units and a connection unit. The controller sequentially determines control values of the light-emitting elements based on comparison between the light amounts detected by the light amount detection unit and a predetermined reference value. The holding units are provided for the light-emitting elements, respectively. Each holding unit holds a control voltage of the controller. When the controller is to sequentially determine control values of a part of the plurality of light-emitting elements, the connection units connects the controller and the holding units corresponding to one or more light-emitting elements for which control values are determined earliest among the part of the plural light-emitting elements, before the controller determines the control values of the one or more light-emitting elements.

摘要： An image forming apparatus and a method of controlling turn-on of light source used therefor are capable of conducting stable image forming operation and maintaining high effective scanning rate while switching the rotation control of the polygonal motor between the internal control by the internal encoder of the motor and the external control by the horizontal synchronous signal outside of the motor. With the apparatus and method, the period of detecting the timing of start of the fast scanning (referred to as SOS period) is T when the driving motor rotates at a predetermined number of revolutions. T becomes shorter by T2 due to the switching from the internal control to the external control. During the shift from the internal control to the external control, the light source is turned on so that the period T1 from turning-on the light source for detecting the SOS timing to the detection of the SOS signal becomes longer than T2. Thereby, turning-on of the light source is surely conducted earlier than the SOS signal detection timing when the rotational control is switched from the internal control to the external control.

摘要： In a color registration deviation correction method or an image forming apparatus, a pattern image is read out, a color registration deviation amount is detected, and a correction amount of the color registration deviation is calculated. On the basis of the calculated correction amount, it is judged whether correction can be made in an interimage period. In the case where the correction can be made in the interimage period, the color registration deviation correction is made in the interimage period, and in the case where the correction can not be made in the interimage period, the color registration deviation correction is made in the two interimage periods.
