摘要： An image forming apparatus includes an intermediate transfer member, a sensor, and two image forming units. Each of the image forming units includes an image carrier, an image writer, two development rollers, and a switcher. The image writer writes an electrostatic latent image on the image carrier. Each of the development rollers selectively driven by the switcher visualizes the electrostatic latent image to form toner images in four colors. The toner images are transferred and superimposed onto the intermediate transfer member to form a color toner image. The color toner image is transferred onto a transfer sheet. One or more marks are formed on the intermediate transfer member. The sensor detects one of the marks. The image writer starts writing in synchronism with a sync clock signal of the image writer output immediately after the sensor detects the mark or output after a predetermined time period elapses after the sensor detects the mark.
摘要翻译：图像形成装置包括中间转印部件，传感器和两个图像形成单元。每个图像形成单元包括图像载体，图像写入器，两个显影辊和切换器。图像写入器将静电潜像写入图像载体上。由切换器选择性地驱动的每个显影辊可以使静电潜像可视化，以形成四种颜色的调色剂图像。调色剂图像被转印并叠加到中间转印部件上以形成彩色调色剂图像。彩色调色剂图像被转印到转印纸上。在中间转印部件上形成一个或多个标记。传感器检测到其中一个标记。在传感器检测到标记之后经过预定时间段之后，图像写入器开始与传感器检测到标记或输出之后的图像写入器输出的同步时钟信号同步进行写入。

摘要： An image forming apparatus capable of decreasing the image unevenness of a superimposed image at the time of forming starting (head) lines of the images in respective colors with different beams in order to decrease a shift of a superimposed image. Let a position, where an image in a first color is formed with a beam A as a leading beam, be (a). Let a starting position of formation of an image in a second color be (b), and one dot (line) of shift arises in the superimposed image. In order to decrease the shift of the superimposed image, image formation is performed with selecting a beam B as a beam which writes a head of the image (c). When image formation is performed for color shift reduction with changing a leading beam for each color image, tonality correction is performed to each beam for subsequent images so as to decrease image unevenness due to the difference between shapes and exposure power of respective beams.

摘要： The sheet separation apparatus for separating a transfer sheet from a toner image bearing photoconductor for use in an electrophotographic copying machine comprises a plurality of separators which are rotatably mounted on a shaft arranged parallel to the photoconductor, and each of the separators is independently urged into pressure contact with the surface of the photoconductor by a spring member through a control member which is substantially integral with the shaft. In one embodiment of the sheet separation apparatus, the control member serves as a protector for preventing toner particles from being scattered from the surface of the photoconductor and in another embodiment of the sheet separation apparatus, the shaft can be turned about a predetermined point of one end portion of the shaft in the direction that the other end portion of the shaft can be moved away from the photoconductor for easy maintenance of the sheet separation apparatus.

摘要： A clamp which spans a pair of endless chains grips the leading edge of a sheet to convey the same into engagement with a photoconductive drum of an electrostatic copying machine or the like. A primary feed roller is driven through one rotation to feed the top sheet from a stack into the bite of the clamp. A cam follower actuated by a cam integral with the primary feed roller moves a release member into engagement with the clamp to open the same and further disengages secondary feed rollers between which the top sheet passes from the stack to the clamp. At the completion of rotation of the cam, the cam follower disengages the clamp to grip the leading edge of the sheet and engages the secondary feed rollers to feedingly grip the sheet. The secondary drive rollers are interconnected with the chains for integral driving movement after the sheet is gripped by the clamp and secondary feed rollers.

摘要： A large number of cards are vertically randomly stored on a horizontal platen. Each card has a serrated bottom code edge contacting the platen, a magnetic chip implanted in a vertical edge and a hook on the upper edge. Selected serrations are removed from the bottom edges of the cards to constitute a selection code. Selected sorting bars are raised into position between the serrations, and a magnet attracts the magnetic chips so that only the selected card having serrations removed corresponding to the raised sorting bars is pulled horizontally backward by the magnet by a distance of one serration. A push bar then engages with the hook of the selected card, and pushes the selected card horizontally forward and simultaneously lifts the selected card clear of the other cards to a retrieval position.
