    1500638 Multimode photo-copying XEROX CORP 18 June 1976 [20 June 1975] 25357/76 Heading G2A In a multimode line-by-line printer wherein an original may be copied while stationary or while moving, the original may be selectively moved at one of at least two different speeds depending on image size desired. As shown, the apparatus comprises a platen 23 for supporting a stationary original and a document feeder 30 movable between an inoperative stationary original mode (phantom line) position and an operative moving original mode (solid line) position, document feeder 30 having feed rollers 50, the speed of which is determined by two speed gearing (detail being given in Figs. 3 and 4, not shown). The projection system for same size copying comprises a scanning lens 26 fixed in the moving original modes, a fixed lens 27 and a lens/mirror 25, a reduced size image being produced by movement of an add mirror 60 into the optical path and by lateral and rotational movement of lens 25 (detail being given in Figs. 6-8, not shown). Lens 25 and mirror 60 are automatically moved into the reduced size copying position on selection of the appropriate gearing, the apparatus reverting to a same size copying mode when feeder 30 is moved off the platen. Three different speeds may be employed Fig. 5 (not shown).

    The invention relates to electrophotographic devices, namely, to a multi-mode electrophotographic copier.
    An electrophotographic photocopier is known, containing an electrophotographic cylindrical image carrier, installed with the possibility of rotation, nodes of the 3 arches, arising, reproducing and reproducing the image, optical system (Scanning a still and moving original, automatic source feeding unit with feed rollers , mounted on the device shaft of the mode selector switch, and the drive, which includes the engine, main shaft, and gear.
    This machine possesses not high enough technical indicators of the operating mode on a scale to reduce the moving original,
     the invention is an expansion of the technological capabilities of the apparatus by introducing a mode of operation to reduce the moving from the original. and e-aCleaning of the image, the optical scanning system of the stationary and moving original, the node of the automatic feed of the original with feed rollers, is installed The drive / starting motor, main shaft and gear transmission are additionally equipped with a high-speed gear pair and a spring clutch, the driving gear of this pair is mounted on the main shaft of the device, and the driven gear and spring coupling are fed to your feed roller. originals.
    FIG. 1 is depicted with a hematically electrophotographic copying apparatus; in fig. 2 - automatic feed unit of the original.
    The electrophotographic photocopier has a housing 1, - an electrophotographic cylindrical carrier of the image 2, a charging unit 3, an exposure unit 4, a display unit 5, are mounted in a bludgeon.
    behind which, in the direction of rotation of the cylindrical carrier of the image 2, the transfer unit is hidden. That image on a sheet of gibkogkhe materialbab, a node for the freezing of the image 7, and a collection tray 8.
    The optical system 9 consists essentially of the lens 10 of the viewing plate 11 below and two moving scanning mirrors 12 and 13.
    The copier has an automatic feeding unit of the original 14 with feed rollers mounted on the device shaft of the switch 5 operating modes of the device, and the automatic feeding unit of the original 14 can be moved from the storage position (next to the viewing plate C to the working Q position above the viewing plate surface ) ..
    A mode switch (not shown) for the originating unit 14 is provided. This switch 25 is used to set the desired mode of operation for the apparatus.
    The drive of the apparatus contains a pair of interlocking gears 15 and 16, forming a gear with a low speed. The gear 15 of the shaft is rotatably supported on the shaft of the originating rollers 17 and is connected to it by means of a spring clutch 18. The apparatus further comprises a high-speed pair 19-20, with the gear 20 of this pair mounted on the main shaft of the apparatus 21, and the gear 19 is installed with the possibility of free rotation relative to the shaft of the feed rollers of the originals 17 and engages with it by means of a spring clutch 22.
    In this case, when the gears 5, 15 and 16 engage, the possibility of introducing the apparatus mode on a scale to reduce the original is obtained.
    The proposed electrographic copying machine has several Qo modes of operation and contains means for copying documents moving or stationary. In addition, it is possible to copy originals with a decrease. With such an expansion of technological capabilities, the device is made compactly, technologically, with improved technical indicators.
