Generates an intermediate image of the log to be copied above.

A sensor 20 is fixedly mounted on the lamp sled 13 and aligned to allow it to scan the bottom side of the support 4.

In FIG. 2, the sensor is shown in a schematic representation in the form of a block diagram. The sensor 20 includes a lamp 21 designed as an ultraviolet lamp. The sensor further includes a photodetector 22 sensitive to the wavelength range of the lamp 21 radiation.

The lamp 21 and the photodetector 22 are aligned such that the lamp illuminates that area of the support 4 that is reflected towards the photodetector 22. A filter 24 that is transparent only to ultraviolet radiation is provided between region 23 and photodetector 22 . Therefore, the sensor 20 illuminates the original 25 placed on the support 4 with ultraviolet light and scans the reflection of this ultraviolet light.

In this embodiment, lamp 21 and photodetector 22 operate in the ultraviolet range. In principle, other wavelength ranges may also be used. In order to separate the additional information from that of the original to be copied, it is important that a wavelength range outside that wavelength range that is sensitive to the copying means is used.

In addition to a display device 7 and a keyboard 8 for starting the copying device or for entering information, each
The control panel 6 includes a terminal 27 for receiving and processing A-solization cards similar to bank cards.

This terminal includes a control device 28 connected to a microcomputer 26. The microcomputer 26 is connected on one side to a display device 7 and on the user side to a control device 29 for the copying means 2. Furthermore, a micro combi coater 26 is connected to a data storage device 30 . Furthermore, the microcombicoater 26 controls the voltage supply of the lamp 21 via a power amplifier 31 at its outlet. The photodetector 22 is connected to a signal amplifier 32 and a threshold l+f+I

However, it is also possible to mark the authenticity data resulting from the adjustment of the adjustment member on the authorization card itself in a manner to be read out by the terminal, whereby the terminal 27 and the microcombicoater 2G can mark the authenticity data on the authorization card itself. The data representing the ultimately coded individual code word in encoded form is compared with the actual adjustment of the adjustment member. If there is a match, it is presumed that the user is indeed the authorized person.

As can be seen from Figures 38 to 3d, the originals 25, 251, 252. ．． 253 is barcode information 35, 358.35b, 351, 351a that is independent of the actual wood information 34 and other than that:
352; Contains 353. In the embodiment shown in FIG. 3a, several barcode rows 35, 35 each having the same information
a, 35b are provided spaced apart from each other and extending laterally across the original document. In the embodiment not shown in FIG. , extending longitudinally and provided on the outer edge, and in the embodiments of FIGS. 3C and 3d, the barcode extends laterally or longitudinally, respectively, between other information 34 of the log. In the embodiment according to FIGS. 3a and 3d,]
- code information is read out transversely in the direction of arrow 36, whereas in the embodiment of FIGS. 3h and 3c, readout takes place longitudinally in the direction of arrow 37. In the illustrated embodiment, the code information distributed multiple times or provided only once on the sheet covers a large area of the original document. Thereby it will be achieved that a smaller document cannot be slipped due to its reproduction under a part of the raw wood that is not covered with barcode information.

In the case shown in Figures 3a and 3b, the code information only provided in those areas of the original document where the actual information is present can be recorded in the usual coloring manner. If the code information extends beyond the area containing the normal information 34, i.e. in the embodiments of FIGS. It is given in no color. According to one embodiment, no image is produced by the copying means, but a color is used which is emitted in the ultraviolet region by illumination with ultraviolet light by the lamp 21 and detected by the photodetector 22.

The individual originals to be copied are divided into different safety groups, for example into corresponding different groups, depending on the code information provided. The microcombicoater automatically sends the microcomputer whenever an authorization card entered into the terminal 27 indicates information authorizing the holder of this authorization card to copy the original of just such a coded group. is designed to activate the copying means 2 for copying operations through a control device M29. If, for example, it concerns logs with different degrees of safety;
The microcomputer compares the information read from the authorization card as to whether the owner is authorized to copy the log with its degree of security represented by the code and read by the sensor 20. If this is the case, a copying operation is performed. Otherwise, copying operations are disabled or stopped. In particular, stopping the copy operation will only take place if, for example, code information distributed over a complete log is scanned over a portion, since a smaller document that is not allowed has been brought down. .

The micro combicoater determines who copied which log, when and how many times, as evidenced by the authenticity card inserted by the terminal 27, and by the barcode information of the original read by the sensor 20. It is stored in the data storage device 30. Data storage device 3
The contents of 0 can be read out, for example, by an associated screen, not shown, or printed out by an associated printer, not shown. Thus, on the one hand, only such documents can be copied by persons authorized to copy, and on the other hand, all data regarding the copying operation are constantly recalled. This is achieved by being remembered as such.

The embodiment shown in FIG. 4 includes additional means for introducing information into the imaging optical path of the copying means. This means includes three flashlight lamps equipped with a parabolic reflector 39. A lens 40 is provided on the flashlight lamp 38 for converting the light from the flashlight lamp into parallel light beams. A so-called light valve formed as a liquid crystal display @ 41 is arranged in the light path following the lens 40 . Following the optical pulp is an objective lens 42 in the optical path.

The objective lens forms an image of the liquid crystal display 41 via the deflection [19] on the drum 9. Not only the deflection mirror 19 but also the elements 38 to 42 are arranged with respect to the machine frame by means of mountings, which are not shown. 2 consisting of a member that forms the image of the liquid crystal display device and a member that forms the image of the original.
The optical paths are arranged offset from each other by 14- so that they do not influence each other optical path. The lamp 14 of the lamp sled 13 and the flashlight lamp 38 together with the light bulb 41 are connected to and driven by the control device 29. In this embodiment, on the copy to be generated by fading-in of numeric or alphanumeric information onto a drum 9 which serves as an intermediate image carrier as a series of characters in an i-like manner driven by a micro combicoater. Mark the cope display data on 1. J

It substantially corresponds to the embodiment shown in FIG.

The microcomputer has a first output and an amplifier 43
and a second output and display driver 44 to drive a light valve 41 to generate a flash of light on the drum 9.

In the embodiments described above, each master document contains coded information that characterizes the master document in relation to its class, eg, its security degree.

Furthermore, the encoded information can also identify the original itself, for example by the file number of the original or by a certificate regarding the content of the original.

Of course, these data are also stored in the data storage device 30.

In the embodiment shown in FIG. 6, a sensor 45 comprising a first read head 46 and a second read head 47 is provided in addition to the sensor 20 described above.

Like the sensor 20, a sensor 45 is fixedly connected to the lamp sled 13 and is mounted thereon and is thus reciprocated together with the lamp sled parallel to the support 4.

The read heads are designed such that when they reciprocate, they respectively scan tracks of the original on or on the support. The output head 46 is designed to be able to read out the unique information of the authentic card. Its output is
It is connected to a microcombicoater 26 which digitizes the output signal and supplies it to a comparator.

The second trailing head 47 is designed to be able to read out the information provided to the original, which is printed on the original or written on a magnetic track. Its output is also connected to a microcomputer, which also forms a digitized signal of the output signal of the second successive head and feeds it to a comparator. An output signal is provided if the information on the information matches, and an activation signal is then provided to the control device 29 for activating the copying means.

However, if the comparators do not provide an output signal due to a mismatch, the copying means will not be activated.

If this second sensor is used, the logs each contain a measuring track for scanning by the first successive head 46 the material-specific properties for them. Characteristic data reflecting the contents of the measurement track is printed on a track parallel to it. By using this second sensor 45, the copying machine detects whether the original is a genuine original or a forgery.

It should be understood that the above description is in no way limiting and that numerous modifications may be made to the disclosed embodiments without departing from the true spirit of the invention.
