摘要： A copying machine wherein successive finished sheets issue from an opening in the front wall of the housing in such positions that the printed matter is observable from above. Successive sheets pass below an observation window which is adjacent to the opening so that the quality of printed matter can be observed from above. The sheets are thereupon inverted so that the printed matter faces downwardly, and are stacked on top of each other in a tray having a bottom panel the inner end portion of which constitutes the observation window. The sheets are inverted in a channel having an inlet below the observation window and an outlet above the end of the tray which is remote from the opening.

摘要： A sheet-holding cassette for a copying machine is formed as a box containing a stack of copy sheets. This box is adapted to be held in the machine with the uppermost sheet of the stack engageable with the paper-advance roller of the machine. A slot is provided in the upper wall of this cassette as well as a guide next to this slot and a deflector in back of this slot so that an extra sheet can be slid along the upper wall of the machine and into the cassette to lie at least at its front edge on top of the stack of sheets in the cassette. Thus as the paper-advance roller is reciprocated down onto the stack it will pick up this extra sheet rather than the top sheet of the stack, allowing a copy to be made on a single extra copy sheet without having to reload the machine.

摘要： In an electrostatic copier using a particulate developer mix the invention provides a source of the mix, a supply ramp having an inlet end located higher than the source, and a conveyor for conveying the developer mix from the source to the inlet end of the supply ramp. The conveyor is composed of an endless flexible belt trained about at least one driven roller and having one end portion which extends into the source and another end portion which discharges onto the inlet end of the ramp. A plurality of pins is anchored in the belt and projects from a conveying surface thereof so as to entrain the developer mix from the source.

摘要： An electrostatic copying machine wherein a carriage is reciprocable between a horizontal copyboard for originals and the flat upper reach of an endless backing belt the outer side of which has a photosensitive surface. The carriage supports at least one exposing device which exposes line images of the original onto the upper side of the upper reach of the belt while the carriage moves from a starting position and the belt is at a standstill. The carriage further supports a corotron which is mounted ahead of the exposing device and charges successive increments of the upper reach, and a developing device which applies toner particles to the electrostatic image on the upper reach. The belt is thereupon moved to transfer the thus obtained powder image onto a paper sheet. The exposing device has several strip-shaped optical imaging components, and the developing device employs a rotary magnetic drum or a set of magnets which are fixedly mounted on the carriage. If the carriage supports several corotrons, several exposing devices and several developing devices, each exposing device contains a differently colored filter so that the powder image is a color image of the original on the copyboard.
摘要翻译： 一种静电复印机，其中托架可以在用于原稿的水平纸板和在其外侧具有感光表面的环形背衬带的平面上方到达之间往复运动。 滑架支撑至少一个曝光装置，其中，当滑架从起始位置移动并且带处于静止状态时，其将原稿的线图像暴露在带的上端的上侧。 托架进一步支撑安装在曝光装置前面并对上部接触的连续增量进行充电的科罗龙，以及将上色剂上的静电图像施加调色剂颗粒的显影装置。 然后将皮带移动以将由此获得的粉末图像转印到纸张上。 曝光装置具有多个条状光学成像部件，显影装置采用固定安装在托架上的旋转磁鼓或一组磁体。 如果托架支撑几个corotron，几个曝光装置和几个显影装置，则每个曝光装置包含不同颜色的滤色器，使得粉末图像是原稿在纸板上的彩色图像。

摘要： An electrostatic copying machine wherein the copying drum and the cleaning unit for the photosensitive layer of the drum are mounted in the plastic casing of a module which can be inserted into the stationary main portion of the housing upon pivoting of a cover to open position. The main housing portion and the cover carry rollers which automatically center the copying drum of a properly inserted module when the cover is moved back to closed position. The casing of the module has a vessel for a supply of developing or fixing liquid and means for automatically feeding liquid to a tank in the main portion of the housing when the supply of liquid in the tank descends below a predetermined level. One of the rollers can be driven by the motor of the copying machine to rotate the drum when the latter is properly centered in the housing.

摘要： Relative movement is effected between an original to be copied and an optical projection system. During such movement, the projection system projects the image of successive strip-shaped portions of the original onto successive strip-shaped portions of a recording medium, to form a gap-free reproduction of the original. The projection system includes a plurality of optical elements at least two of which are of positive refractive power and project an image of a strip-shaped portion of the original into an intermediate image plane and from there onto the recording medium. At least one of the optical elements of the projection system comprises an element having a lenticular layer of positive refractive power and a reflective layer combined therewith.

摘要： A copying machine has a scanner movable in a forward direction to scan a master sheet and in a reverse direction to return to its starting position. A drive shaft of the machine rotates similarly forwardly and backwardly to displace this scanner and is connected to a pair of cams, one of which controls a pickup arm for sliding the uppermost sheet off a paper supply stack and the other of which is connected to a pair of pinch rollers which advance the picked up sheet through the imaging mechanism of the machine. Each of these cams has an operating portion which actuates the respective machine element during forward rotation of the cams, but which is brought out of engagement with the respective cam follower during reverse operation of the machine so that during return of the scanner to the starting position the pickup arm and pinch rollers are not operated.

摘要： A drum assembly for an electrostatic copier having a stationary frame comprises a cylindrically tubular drum whose outer surface carries a light-sensitive coating. A pair of rings are snugly engaged with the outer ends of the drum and are mounted via roller bearings on the frame for rotation about a common ring axis. A support sleeve is non-rotatably fixed to the frame between the rings and within the drum and has an outer surface which normally lies out of contact with the drum and only serves to support the drum as it is being fitted into the machine, so as to protect its delicate light-sensitive coating. One of the rings can be removed from the frame so as to allow axial withdrawal of the drum.
