摘要： In this digital color copier, laser beam scanner units of the same configuration are arranged in parallel with each other, and all are controlled in a unified manner by a laser control unit provided outside the units. In order to synchronously rotate the polygon mirrors in a precise manner, the speeds of rotations of their motors, fed back from tacho-generators are compared to the reference frequency generated from an oscillator so as to allow a motor control circuit to control the driving motors of the polygon mirrors. Further, the BD signals from beam detectors (BD) are fed back to the laser control unit so that all the BD signals from the laser scanner units for black and the three colors can become synchronized with each other, thus enabling control of the polygon mirrors.

摘要： The image processing circuit essentially includes an image data input portion, an image processing portion, an image data output portion, an image memory composed of a hard disk drive etc., a central processing unit (CUP), an image editing portion, an external interface portion. Based on the determination result of the laser recording status determination by the CPU, an LCU also serving as a mirror motor control device, stops or retards the drives of driving motors, one by one, in the order of their completion of laser recording. The image processing circuit may further has a mode manager for checking the usage frequencies of the first most processing mode in which the input image information is image processed as color image information and the second processing mode in which the input image information is processed as monochrome image information. Moreover, the image processing portion may further has an original discriminating portion for determining the color type of an original.

摘要： An object of the invention is to reproduce a faithful image irrespective of thermal expansion of a light-scanning unit and to reproduce a faithful image without enhancing the strength of the light-scanning unit excessively. A pair of supporting portions of a light-scanning unit, each having a flat face, are supported in linear contact with a right column-shaped supporting member provided with the apparatus body. The light-scanning unit is provided on the supporting member near to a starting position where writing image data on a photosensitive body with a scanning line is started in a main scanning direction so as not to be mutually displaced relative to the supporting member. Thereby, the light-scanning unit is allowed to extend in the longitudinal direction of the supporting member due to thermal expansion of the light-scanning unit. Also, an elongated supporting member made of stainless steel penetrates a base body of a light-scanning unit made of synthetic resin which scans in scanning line of laser light on the photosensitive body to exposure, to support the light-scanning unit. The center of gravity of the light-scanning unit is positioned near to the supporting member and vertically below the supporting member, to make the moment acting on the light-scanning unit small and hold the light-scanning unit in a stable state. The supporting member suppresses deformation of the base body due to thermal expansion.
摘要翻译：本发明的目的在于，不管光扫描单元的热膨胀如何，再现忠实的图像，并且在不增加光扫描单元的强度的情况下再现忠实的图像。具有平面的光扫描单元的一对支撑部分与设置有装置主体的右柱状支撑构件线性接触地支撑。光扫描单元设置在靠近起始位置的支撑构件上，其中在扫描线上的感光体上的图像数据在主扫描方向上开始，以便不相对于支撑构件相互位移。由此，由于光扫描单元的热膨胀，允许光扫描单元在支撑构件的纵向方向上延伸。此外，由不锈钢制造的细长支撑构件穿透由合成树脂制成的光扫描单元的基体，其在感光体上的扫描激光线上扫描以曝光，以支撑光扫描单元。光扫描单元的重心位于支撑构件附近并且垂直于支撑构件的下方，以使作用在光扫描单元上的力矩较小并将光扫描单元保持在稳定状态。支撑构件抑制由于热膨胀而引起的基体的变形。

In a space portion where all light-scanning units are housed, an air-exhausting fan is provided in the vicinity of the light-scanning unit nearest to the thermally fixing unit, and an air hole is formed at a position farthest from the thermally fixing unit. Additionally a temperature sensor is mounted on the light-scanning unit nearest to the thermally fixing unit. Rotation speed of the air-exhausting fan is controlled so that the temperature detected by the sensor does not exceed a predetermined temperature limit.

摘要： An object of the invention is to provide an image forming apparatus in which a unit can be attached to the apparatus body in a status where a correct positional correlation between a photoconductive drum and each of other process devices mounted on a unit is maintained. A photoconductive drum is positioned within a copier body by a rotating drive shaft, and the other process devices mounted on a process unit are positioned within a copier body by a boss and a locking member. The boss positions the rotating drive shaft within the copier body. Since the locking member is fitted onto a front-side end of the rotation drive shaft, the locking member is positioned within the copier body by the rotating drive shaft. The other process devices mounted on the process unit are positioned within the copier body by the rotating drive shaft via the boss and the locking member. Accordingly, the photoconductive drum and each of the other process devices, which should maintain a predetermined positional correlation with each other within the copier body, are both positioned within the copier body by the rotating drive shaft.

摘要： A plurality of first base images for a base color are formed in accordance with a predetermined adjustment value. A plurality of first correction images for a correction color to be a subject for correction are formed on the first base images in accordance with a predetermined adjustment value. The first correction images are displaced within a predetermined range. The first adjustment value is determined from changed adjustment values. The second base images for the base color are formed in accordance with the predetermined adjustment value while the second correction images for the correction color are formed in accordance with a plurality of adjustment values determined based on the first adjustment value. One second adjustment value having an extreme is determined from the plurality of adjustment value candidates. These processes are repeated to determine a final adjustment value. The adjustment value for the correction color is corrected to the determined final adjustment value.
