摘要： In conventional color digital copy machines, when copying in color mode, the polygon mirror of the laser beam scanner for black, which is driven at a higher speed than those of the other colors, is switched to a slower speed in conformity with the speed of the polygon mirrors for the other colors. However, a drawback of this structure is that, especially when switching from monochrome to color mode, the time required to obtain the first copy is lengthened, and the operating efficiency of copying is poor. In the present invention, when copying in color mode, the rotation speed of the polygon mirror of the laser scanner unit for black is not changed at all, but, by skipping certain mirror surfaces of the polygon mirror, and/or by skipping certain of a plurality of laser light sources, the scanning density of the laser scanner unit for black can be brought into conformity with that of the laser scanner units for the other colors.
摘要翻译：在传统的彩色数字复印机中，当以彩色模式进行复印时，以比其他颜色更高的速度驱动的用于黑色的激光束扫描器的多面镜被切换到较慢的速度，多面镜为其他颜色。然而，这种结构的缺点是，特别是当从单色切换到彩色模式时，获得第一拷贝所需的时间延长，复制的操作效率差。在本发明中，当以彩色模式进行复印时，黑色激光扫描单元的多面镜的旋转速度根本没有变化，但是通过跳过多面镜的某些镜面，和/或通过跳过某些多个激光源，用于黑色的激光扫描器单元的扫描密度可以与其他颜色的激光扫描仪单元的扫描密度一致。

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： A data-processing system consisting of a portable terminal device and a copying machine can effectively work with protection against breakage of data stored in the terminal device. The data-processing system is constructed to work on the following principle: When a given period is measured by a timer for starting the power saving mode, a portable terminal device provides a copying machine with a signal informing of starting the power-saving mode. The copying machine, which received the power-saving-mode starting signal, provides in later the portable terminal device a signal requiring the terminal to cancel the power-saving-mode. When a given period is measured by a timer for starting the power saving mode, the copying machine provides the portable terminal device with a signal requiring the terminal device to start the power-saving mode. A CPU, which received information on request of power-saving-mode, executes the power saving mode. The portable terminal device and the copying machine as the former being mounted on the latter can simultaneously execute the power saving mode, preliminarily sheltering data in the storage.

摘要： The present invention is directed to the provision of an image forming apparatus capable of effectively preventing the formation of images related to illegal conducts by making provisions so that, even in situations where images can be formed based on image data outputted from any arbitrary image output apparatus, the image output apparatus which outputted the image data can be identified without fail. When image data is inputted from a portable image output apparatus, first it is checked whether identification information has been inputted together with the image data, then an image of an identification pattern is created, and image formation is performed based on image data obtained by attaching the image data of the identification pattern to the input image data. On the other hand, when image data is inputted from a fixed image output apparatus, first it is checked whether identification pattern data is included in a designated position in the image data, and then image formation is performed based on the input image data. The image thus formed by the digital copying machine contains the image of the identification pattern by which the image supply device that outputted the source image data is identified.

摘要： A conventional image forming device having a plurality of image optical scanning recording sections has had a drawback of being incapable of correcting printing positions of the image optical scanning recording sections with high precision by using a small-scale circuit. In the case of an image forming device of the present invention, a variable clock generator 114 having a voltage control oscillator (VCO) 114a is provided therein as reference clock signal generating means of laser control system of each of image optical scanning recording sections (LSU) for cyan, yellow, and magenta. By so doing, during an invalid printing period prior to a valid printing period, frequencies of the reference clock signals of the LSUs for cyan, yellow, and magenta are adjusted in accordance with offsets of printing start positions of these LSUs with respect to that of the LSU for black, so that printing offsets are eliminated. As a result, the printing start positions are made to coincide with each other with high precision even with a small-scale circuit.

摘要： An image data input portion captures one line of data. The captured RGB data is color-converted into image information of a different set of colors, through the image processing portion. The converted data is written at a set up address on an HD. One page of image information is written onto the HD whilst the HD's address is sequentially incremented by 2. When two colors of data need to be retrieved in parallel from the HD, the data of the colors can be alternately written in. A CPU controls tandem recording units Pa, Pb, Pc and Pd so as to perform printing of respective colors, with a time shift one to the next of a period equal to the pitch of photoreceptor recording units.
