摘要： A color copying machine contains a scanning unit driven by a motor for applying a color scanning beam onto a manuscript, a photoconductive drum operable to rotate for being exposed to the scanning beam to form on a peripheral surface thereof a latent image of the manuscript. The color copying machine further contains a device for applying a toner to the latent image to form a toner image, and a transfer drum for holding a record sheet onto which the toner image on the photoconductive drum is transferred. A main controller calculates data representative of a speed of the motor in accordance with a magnification rate of the copy image to be formed on the record sheet to the image on the manuscript, and outputs a pulse signal whose pulse rate is proportional to the calculated speed data. The main controller outputs the pulse signal to a controller which drives the motor at a speed determined by the pulse rate of the pulse signal. Thus, the speed of the scanning unit is determined in accordance with the magnification rate.
摘要翻译：彩色复印机包含由用于在原稿上施加彩色扫描光束的电动机驱动的扫描单元，可操作以旋转以便暴露于扫描光束的感光鼓，以在其外围表面上形成原稿的潜像。彩色复印机还包括用于向潜像施加调色剂以形成调色剂图像的装置，以及用于保持转印有感光鼓上的调色剂图像的记录纸的转印鼓。主控制器根据要在记录纸上形成的复印图像的放大率根据原稿计算表示电动机的速度的数据，并输出脉冲率与计算出的速度成比例的脉冲信号数据。主控制器将脉冲信号输出到以由脉冲信号的脉冲速度确定的速度驱动电动机的控制器。因此，根据放大率来确定扫描单元的速度。

摘要： A color copying machine includes scanning device for applying illumination onto a color original to effect a scanning operation. A color separator includes a plurality of optical filters of different colors, each of the filters allowing a predetermined light component of the illumination to pass therethrough during each scanning operation so as to apply it onto a photoconductive drum charged uniformly to form an electrostatic image thereon. Color toner is applied to each of the electrostatic images during the rotation of the photoconductive drum. The toner image on the photoconductive drum is transferred to a record sheet on a transfer drum. Two sensors are provided for sensing the initiation of each scanning operation and the position of the record sheet on the transfer drum. A control circuit detects, in response to the outputs of the two sensors, start and end timings of the transferring of each of the toner images onto the record sheet. The control circuit controls the transfer drum to rotate at the same speed as the photoconductive drum during the transfer of each toner image to said record sheet, and controls the transfer drum to rotate, during a time interval between the two consecutive transfer operations, at such a speed that a leading edge of the record sheet on the transfer drum is brought into agreement with a leading edge of each toner image on the photoconductive drum.

摘要： In a recording sheet conveying device comprising: a dielectric sheet which moves at a predetermined speed while electrostatically retaining a recording sheet on the outer surface thereof; a charger positioned on the side of the inner surface of the dielectric sheet, to induce electrostatic attraction forces between the dielectric sheet and the recording sheet; and a deflector roll having an electrically conductive layer as an outer surface thereof, the deflector roll being confronted with the charger and adapted to push the recording sheet against the dielectric sheet, the number of electric charges provided by the charger is so adjusted that electrostatic attraction forces acting on the rear end portion of the recording sheet are weaker than those acting on the front end portion of the recording sheet, whereby the recording sheet is prevented from being wrinkled when electrostatically retained on the dielectric sheet.
