Method and apparatus for generating a desired number of sets of copies based on sets of originals
Master copies

Telephone information and orders are only possible after written Confirmation binding

The invention relates to a method for generating a desired Number of copy sets with a number of copies arranged in the desired order and position due to of master sets with a number of master copies that are in vorbestinuritar Order are arranged. The invention also relates to a device for carrying out such a process Procedure.

Known copier devices make it possible to use a master copy, which has been arranged in a reading station to make one or more copies. More templates can be brought into the reading station one after the other in order to make copies of these originals. However, if a template set is to be copied from a plurality of original lines exists if, to give an example, eight copies are made of a 20-page master copy are to be, then with such a copier: ^ an additional work step is required to collate the copies made, i.e. to collate the copies made arrange> that the order and location of the copied pages for each the eight copy sets corresponds to the order and position of the original seldom in the original set. This collation can It was carried out in the manner that one after the other dia twenty Bringing original pages from the original panel into the reading station, a single copy of each original page farti.gt and repeat the process eight times to produce dia to generate the desired number of copy sets. This variation can be referred to as a so-called "recirculation process" (see U.S. Patent Re. 27,976).

Another known method for generating a desired Number of copy sets are brought to the reading station only once for each document page of the document set. While the template is in the reading station copies them as often as is necessary to get the desired number of copy sets (in the example mentioned, that is

709837/0853

copied eight times). The copies are then made either manually or mechanically sorted so that collated copy sets are obtained.

The method of "recirculation" is applied to collated Get copy sets where the order and The position of the copied pages corresponds to the order and position of the original pages, or is a sorting process for collating then in both cases disadvantages have to be accepted v / earth, namely a high expenditure of time for the operator and / or an increased expenditure on paper transport and handling facilities. When "circulating" the documents there is the additional disadvantage that the original documents are exposed to the risk of wear or damage due to excessive mechanical stress, if higher Copying requirements required.

The invention is based on the object of specifying a method of the type in question that enables the production of collated Copy sets with copies arranged in the order and position corresponding to the original sets on a comparative basis enables fast and economical orphan.

In a method of the type mentioned, this object is achieved according to the invention in that a train is electrical Signals that represent the image information of the template set are generated that the electrical signals are stored and that the stored signals as often as it corresponds to the number of desired copy sets in selectable Signal sequence are fed to a printer recording the image information of the signals on a copy material, so that it produces the desired number of sets of copies containing the copies in the desired order.

709837/0853

Because electrical signals are generated based on the image information of the original pages and are stored and can be called up from the memory in a selectable order in order to drive a printer with these signals, that converts the information from these electrical signals into an image recording on the copy material is the possibility opened, a desired number of copy sets with copies arranged in the desired order on the simplest and most economical way to manufacture by means of the printer. By choosing the order and repetitions accordingly When reading out the memory for the operation of the printer, the desired number of collated sets of copies without the need to sort the copies or "recirculate" the originals.

The invention is also based on the object of providing a simply constructed device for the reliable implementation of the Procedure to create.

According to the invention, this object is achieved by a device which is characterized by a reader for generating a train of digital signals, dia represent the image information of the individual pages of the template set, an electronic memory for recording and Storage of the information represented by the digital signals ^ an electrical signal supplied from the memory that contains the image information of the master copies represent, responsive printer for producing an image record on copy sheets and a Data processing device for reading out the image information from the memory, for converting this information into electrical signals to which the printer responds and, if necessary, to repeatedly feed these signals to the printer in the desired sequence.

A light beam 11 from a light source 12, for example from a laser, becomes a cylindrical lens optics 13 thrown, which spreads the light beam around a long, narrow light strip or so to speak sin "line image" to generate on the template, which in an exposure station 14 is scanned in such a way that the line image, after it has been reflected by mirrors 15 and 16, scans the original from one end to the other. A Fald lens 17 transmits the light streak to a Swischsn pupil plane on the surface of the mirror 16 used for scanning the original pages passes through a lens 18 which is used to generate a well planar image field in the exposure station 14.

The master copy is shown as a reflection master, and the reflected light beam is reflected a second time by the mirror 16, that is, by a for scanning the Galvanometer 19, which serves as the master copy, is driven is. The reflected light streak then passes through an imaging lens 20 and falls on a charge-coupled one Receiving device in the form of a CCD group 21. Through the CCD group 21, the lines of the original are successively received from oban downwards, synchronized with the scanning of the original by the illuminating light strip. In the exemplary embodiment, a CCD unit 22 is made from a device made by Fairchild Corp. manufactured linear CCD group rir. 121 and a Fairchild Denonstration PCB built for the CCD group.

An original transport is schematically shown in FIGS. 1 and 2 26 for feeding the sheets of an original set 27 to the exposure station 14. The document transport 26 has a control unit which is discussed in detail below.

The original reading device IO does not need that shown in FIG Structure, but can be in the most varied Wisely designed sain. For example, it could be a reader such as that disclosed in US Pat. No. 3,733,185 is known, which shows a device bsi which a scanning light source through a color slide on a sentence three photosensors fall, each selectively responding to a different, specially assigned length of the trowel, for example on the wavelengths for red, green and blue. The photosensors generate electrical signals that the red, Show green or blue information on the slide.

The Faclimann is aware that several known Template reading devices already exist which are suitable for reading information on a medium to convert electrical signals representing this information.

The output signals from the CCD unit 22 of the document reader 10 are in analog form and are an analog-to-digital converter via a data transmission link 28 29, which converts the signals into a train of digital, discrete output signal levels. These digital Data that, together with its own synchronization signals for the Representation of the individual scanning lines and the side information transmitted via data transmission links 3O, 31 and 32, respectively become a read buffer controller 33 supplied. The synchronization signals of the data transmission link 31 for the line scan can be from the main oscillator 24 to be taken off the one pulse at the beginning of each

709837/0853

lines scan made by the CCD group 21. The synchronization signals of the data transmission link 32 for the page scan can be from a digital encoded shaft angle encoder 34 (SAK) are generated, which is assigned to the galvanometer 19. This encoder emits an electrical pulse at the beginning of the scan on each side.

The read buffer memory controller 33 is clock-wise image information signals in the parallel N-bit data pattern in one of two read buffers 35 and 36 to temporarily store the signals. The controller 33 is used Standard modulo N counters that can be operated upwards / downwards with the size of the two read buffers 35 and 36 dependent modulo H. The controller 33 sends the parallel data to one or the other of the buffer memories 3 and 36, depending on the state of a digital gate contained therein. The entry in the read buffer control This is effected in the usual way, using the multiphase clock 23 as a timer. The control 33 is also used by counting N parallel bits of the encoded data to provide the addressing required for the Read buffer memory when it is full.

The buffer memories 35 and 36 can be of any known type Wise be formed, for example, bipolar metal oxide semiconductor memory (MOS) or charge-coupled (CCD) memories. For example, this can be the case with the read buffers by MOS memory No. 21Ο2Λ for direct access from the company Intel Corporations, deal with multiple logical components, see that of the above Company published book "Memory Design Handbook", 1975, pages 7 to 15. In this case, the controller 33 can be a Logic card Mr. M 238 from Digital Equipment Corporation with dual, synchronous up / down / down counters in connection be provided with suitable control logic.

709837/0853

When one of the buffer memories 35 and 36 is full, which is determined by the up / down counters in the controller 33 then, when this event occurs, a central one Data processing unit 37 (GPU) thereby in knowledge set that it is supplied with an interrupt signal. The data processing unit 37 can, for example be formed by a mini computer, for example a PDP-11 series computer manufactured by Digital Equipment Corporation is suitable is to carry out arithmetic and logical operations, to decipher commands and the temporal assignment of the function to control the Paripheriesysterne via a bus 33, via the bus 33 are all components of the computer system and the Peripherals in connection with each other and in data exchange. The bus 3 <J can be one from Digital Equipment Corporation manufactured part called "UNI3US". The data exchange between the controller 33 and the bus 38 can be connected via an interface 39 provided for universal use (for example DRIL-C from Digital Equipment Corporation), which consists of three functional areas: address selection logic, interruption control logic and device interface logic.

An interface 40 for direct memory access (for example DRIL-B from Digital Equipment Corporation) works directly to or from memory and consists of four registers: command and status, word count, bus address and data. The interface 40 takes care of the data exchange zv / ischen the buffers 35 and 36 and the bus 38. The bus address for the read buffer memory data is under Use of common accounting program techniques in one Read-write memory 41 stored for later reading, which takes place when the encrypted data through the interface used for direct memory access

Ai

to the bus 33 to be in one or both of two main memories 42 and 43 in accordance with a memory controller 44 to be saved. The main memories 42 and 43 and the memory controller 44 can be in the form of the Disk storage system model 95OO from System Industries Inc., Sunnyvale, California, USA. By the aforementioned accounting process kept track of all transfers from read buffer memory to main memory is held, and when a page sync signal is detected from the read buffer controller 33:, another interrupt signal is generated and fed to the data processing unit 37 to cause these only the addresses of the main memory for the relevant page, which identify the start and end of this page can hold in read-write memory 41. Each of the main memories 4 2 and 43 is large enough to hold information one to store a predetermined plurality of pages of the master copy.

For purposes of the present description, storage devices be classified in such a way that a division into memory for "total access" where simultaneous access commands for two different addresses can be met, and in memory for "not total Access "is carried out with which simultaneous access to several addresses is only possible if these are in a special subgroup. In the embodiment of Fig. 1 are for the main memory 42 and 43 memories with "not total access" are provided, such as, for example, conventional magnetic disk memories pose with movable head. With such a memory, simultaneous addressing is only possible with such Addresses possible that are in a subgroup, a so-called

709837/0853

AS

th "cylinder" lie. With a copier as discussed here, the problem of keeping intact of the document sheet stack do not solve if only a single such memory is provided because the reader and the printer generally do not work from the same memory subset.

The binary data can be received by the reading device IO at the controller 33 at a rate that the The speed with which the data can be transferred to the main memories 42 and 43 differs. Such a deviation is due to the fact that the main memories can be loaded at a rate

which differs from the speed at which the reader 10 works. aside from that

there is also the fact that the case can be given, that the main memory is not in the same moment in dsm the reading device 10 begins with the data transmission in the operating state suitable for the data recording.

For example, when the main memories 42 and magnetic disk memories with movable heads are They are usually able to provide 16 2/3 milliseconds of data transfer time (N bits) per disk revolution following store the finding of an initial trailer identifier on the disk by the magnetic head. The reading activity would have to be delayed in this case until such a label is found. In the worst case, it can here the period of 16 2/3 milliseconds for one full Revolution elapse after the reader is ready for data transfer. The controller 33 effects therefore that one of the two read buffers 35 and 36 is loaded while the other buffer memory is delivering data to one of the main memories or is waiting to deliver data. That is, the one designed for direct memory access Interface 40 enables data exchange between a reading

709837/0853

Buffer memory and the bus 38 concerned, while the other Read buffer memory with the converter 29 is in connection. In the case of the magnetic disk storage devices described, anyone can Read buffer preferably store K bits of data. Of course, if other forms of main memory are used, the size of the read buffers and the Up / down counter of the read buffer memory controller 33, be adapted to the possibilities of the memory.

As an example of the function of the parts described so far assume that the operator wishes to collate eight To make copy sets from a copy master set, which consists, for example, of twenty sheets and its Sheets are stacked in the document transport 26. The operator makes the appropriate setting on an operating control panel 46. In the present example, let Assume that each of the main memories 42 and 43 can store only one amount of information, the 15 original pages is equivalent to. The operating control panel 46 can be a selector switch and display device which is the central Data processing device 37 programmed via an interface 48 provided for universal use, which previously Interface 39 described is similar.

The Data processing device 37 corresponding to the switch setting on the operating control panel 46 is a read control unit 49 to commence operations. The control unit 49 is connected to the central data processing unit in data exchange via another, for universal use provided interface 50 in order to put the document transport 26 into operation, which in turn places a document in the exposure station 14 transported. The control unit 49 turns on the light source 12 and the CCD group 21 receives Light reflected or transmitted by the original (if the original is a slide).

709837/0853

For example, as the scan proceeds, the read buffer memory 35 receives and stores data (containing Image information and synchronization signals). When the controller 33 is transferring N bits of data to the buffer memory 35 has allowed, the stored data are, for example, transferred to the main memory 42 in the manner described, and the encoded data stream is switched to the buffer memory 36. The data processing unit 37 monitors the counting process in such a way that the scanning of the original is interrupted when both read buffers are full. However, it is unlikely that this will occur, as it is Scanning process is slow due to its nature, compared with the functional sequences of the circuit.

When the controller 33 stops transmitting N bits of data to the Buffer memory 36 has allowed, those in the buffer memory 36 located data are now also transferred to the main memory 42.

When scanning subsequent pages of the original, the above described processes are repeated until either all template sites are scanned and the data thus obtained is in the Main memory 42 are stored or until this memory is filled. It is recalled that in the illustrative, Considered example here the operator wishes to copy a set of 20 original pages and that each Main memory is only able to store the data of about 15 original pages.

The central data processing unit 37 is with the capacity the main memory is preprogrammed and has an accounting function, which holds the track address of the data entered into the main memory. When the main memory becomes full, causes the data processing unit 37 that the memory

709837/0853

The controller 44 begins to address into the main memory 43. The data can now be read out of the main memory 42 and transferred to one of two print buffers 52 and 54 are transferred (which may be designed in a similar form to the buffer memories 35 and 36), the transferring by means of an interface (similar to deia Interface 4O) for direct memory access, the data exchange takes place between the buffers 52 and 54 and the bus 38 is used. A timing from a print buffer controller 60, that of the read buffer controller 33 can be designed similarly and can contain up / down counters to read out the Controlling data from one of the print buffers is accomplished by using a clock in printer 62 and a data link 63 reached. The data transmission between the buffer controller 60 and the bus 38 can be via an interface 64 take place, which is similar to the interface 39. In this way, the one print buffer transfers data to the printer, while the other print buffer stores data from a main memory can receive, so that the printer does not have to wait until the read head of the main memory is on the correct Magnetic disk track is set and the beginning-trailer "indicator has found. The clock of the printer is asynchronous with respect to the clock of the reader, so that the reader and the printer can work at different speeds.

Printer 62 can be of any known type. For example printers such as those known from US Pat. Nos. 3,783,185 or 3,689,935 come into consideration. Here too however, as with the reader, other suitable devices can be used Find use. Fig. 3 shows an example, with schematically different stations of an electrographic Device 71 and an image forming device 72 are shown.

A laser 74 is provided as the radiation source, which throws a beam through an acousto-optical modulator cell 76.

709837/0853

The modulator cell has an acoustic transducer and modulates the laser beam due to electrical signals, which are supplied by a digital / analog converter 77, such as it is also shown in FIG. The modulated beam v / ird in deflected an Oeflektor 78 in a known manner, for example of the type shown in U.S. Patent No. 3,783,185. The bundle is at a point indicated by 30 on a photoconductive belt 82 in focus.

The photoconductive belt 82 has a photoconductive layer with a conductive backing. Such tapes are known see, for example, U.S. Patents 3,615,406 or 3,615,414.

The photoconductive belt 82 rotates around drive rollers 84,85 and 86 at constant speed driven by a usual main drive 88, which is driven by a prerecorded Program from bus 38 via a data processing link 89 is controlled. The moving belt 82 passes through various stations in sequence, first of all a charging station 90 for primary charging, including, for example, a conventional corona charger can, which is suitable to charge the surface of the belt to about 500 volts, then the point 80 where the Beam of light on the moving photoconductive belt is focused so that a latent, electrostatic image is generated in it by selective charge depletion is, and then passes through a development station 92, in which the latent image with finely divided, charged toner particles Is brought into contact with the photoconductive layer in a manner defined by the latent image Cling configuration. The development station 92 can be in of any known type, for example as a magnetic brush developer. An example of one of these Development station is shown in U.S. Patent 3,543,720.

709837/0853

The belt 82 next passes a transfer station 94 in which the toner particles are in their imagewise configuration onto the receiving surface of a copy sheet 9G are transferred, on which surface the toner particles then can be melted down before running again the belt 82 passes through the loading station 90 in a conventional manner Cleaning station 93. The copy sheets 96 where-es can be paper from a roll or sheets cut in a stack, are located in a container 100 of which it is fed to the transfer station 94 along a path defined by a continuously running belt 102 At the transfer station, the copy sheets are grounded in contact by means of drive roller 85 and pressure roller 104 with the photoconductive belt 82 to effect the transfer of the toner image to the copy sheet 96. In the end the transferred image is fused onto the copy sheet at station 106 from which the sheet is sent to an output bin 108 is delivered.

It will be apparent to those skilled in the art that the information from deflector 78 is in time coordination with movement of the tape 82 must be dispensed so that the relative position of each discrete image portion on the tape 82 of the relative position corresponds to the corresponding image area on the master copy. A connection 109 is schematized in a dashed line indicated, which runs from the main drive 88 to a conventional shaft angle rotary encoder 110 with coded value indication. The rotary encoder 110 in turn carries a series of clock signals from the print buffer control 60 (FIG. 1) via a dashed line drawn data transmission path 63a (63 in Fig. 1), as already mentioned above. Line synchronization signals from Main oscillator 24 (Fig. 2) are via a data processing link 63b (63 in Fig. 1) is fed to a deflection frequency generator 112 (which is of a known type, for example it is the commercially available deflection / signal generator, model 1002 from Wavetek Corp.),

709837/0853

the one saw tooth signal generator and one voltage regulator oscillator contains. The deflection frequency generator 112 converts line synchronizing signals into a variable frequency signal for driving the deflector 78 around.

During the printer 62 from one of the print buffers 52 or 54 works / positions the read head of the main memory 42 on the correct magnetic disk and the correct one Disk track for the next N bits of data, as addressed in the read / write memory of the data processing unit 37 searches for an initial flat rate indicator and begins with transferring data to the other read buffer. When all of the data stored in main memory 42 is have been transferred to printer 62 (about 15 pages dss 20-page template set in the present example), the data processing unit 37 causes, under program control, that the data are taken from the main memory 43 (because data is filled, the last 5 pages of the template list correspond, the filling was carried out while the printer was operated from the main memory 42) and that this Data are fed to the printer. After all of the 20 master copies have been made by the printer is, the main memory 42 is made accessible to the printer againv and the process is repeated until the desired eight sets of copies have been made by the printer. Ground in this way all eight copy sets automatically at the output part of the printer collated.

In the example above, it was assumed that the master copies are originals written on one side and that the copies are also one-sided. The present invention enables However, it is also possible to make double-sided copies of one-sided originals and one-sided copies of two-sided originals or to make double-sided copies of double-sided originals. A making collated, double-sided

709837/0853

Copies of main-side originals are possible is to make the setting on the operation control panel 46 so that the data processing unit 37 programs is that the inside of every second original page is copied by the printer onto successive original sheets will. Then the original sheets are turned over and passed through the printer again so that the reverse sides can be provided with the content of the skipped template pages.

In order to produce single-sided copies of double-sided originals, one original side can be scanned and theirs Information is stored in the main memory. Then the templates are turned over and passed through the straightening station again 14 so that the information on the back sides is scanned. For the operation of the printer now read out the information of the first original page from the first scanning process from the memory, so the Information on the first page of the original in the second scanning process, then the information on the second page of the original in the first scan, then the information of the second original page in the second scan, and so on. Bilateral Copies of two-sided originals can be made in a similar way, the only requirement being that that the data processing unit 37 is programmed so that it reads data from the main memories 42 and 43 in the correct Page sequence removes and that the original set and the copy set are recirculated again by the reader or the printer passed through v / earth.

A further exemplary embodiment is shown in a schematic block diagram in FIG. Parts of the second embodiment, the corresponding parts of the first exemplary embodiment are identical with the same reference numbers, which are marked with a dash (·), designated. Because of a purification of these parts v / ird

709837/0853

refer to the previous description.

It will be recalled that in the first execution, two Main memories 42 and 43 are provided so that the printer can work from one main memory while the read * device transfers data to the other main memory. Two read buffers 35 and 36 are provided for the waiting time for data transfer to and from the main memory, which would otherwise be due to the waiting time the length of time that the mechanical parts (the magnetic disks and the read / write head) of the main memory would require, to adjust.

In the second exemplary embodiment shown in FIG. 4, the data are supplied from the document reading device 10 under program control from the central data processing unit 37 * via an interface 122 for direct memory access and the bus 38 * to an electronic memory 120 for "total access". It should be remembered that a "total access" memory is a memory in which simultaneous access commands for two completely different addresses can be complied with. Examples of such memories are core memories, drum memories,

Disk storage and solid-state storage using CCD devices or magnetic bubbles. The data becomes the digital / analog converter 77 'and to printer 62' via bus 38 * and another, transmit interface 124 designed for direct memory access, to operate the printer in the same manner as in the first embodiment.
