Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a copying machine such as a digital color electronic copying machine, and more particularly to a copying machine provided with measures for preventing forgery of banknotes and securities.

[0002]

2. Description of the Related Art In recent years, digital color electronic copying machines have become popular, and most of them are used for useful purposes. However, on the other hand, with the high performance of copying machines, anyone can easily obtain a copy with high resolution and excellent color reproducibility. Therefore, it is possible to execute a serious crime such as duplication of banknotes or forgery. Is happening.

For this reason, the manufacturer of this type of copying machine is considering installing a banknote recognition system in the copying machine in order to prevent as much as possible a crime such as forgery of banknotes that has a great social impact. There is. This bill recognition system stores characteristic data relating to bills in the copying machine in advance, so that even if a bill is to be copied, the copying machine main body determines that the bill is a bill and prints out based on the determination result. At this time, for example, the copy is filled and output.

As an example of such a bill recognition system, for example, Japanese Patent Laid-Open No. 4-227365 discloses a process means for determining the identity between a read input image and a specific image and reproducing the image based on the determination output. A control type copying apparatus is disclosed, and Japanese Patent Application Laid-Open No. 4-227.
No. 367 discloses an image in which the identity of an input image and a specific image is determined in the same manner as the former, and the process means for performing image reproduction is controlled in a form in which image reproduction is prohibited based on the determination output. A processing device is disclosed.

Further, in the above-mentioned prior art example, even if a copy prohibited object such as a banknote is copied, specific data which is difficult to be visually recognized by the naked eye is printed on the copy output, thereby copying. It is possible to specify the machine, date and time, etc. that performed, so that even if a banknote or the like is copied by normal copying, the copied banknote or the like can be traced after the fact, and the specified data can be scanned with a scanner or the like. The means by which it is possible to detect the counterfeit by reading it are shown. Incidentally, as this type of identification data, machine-specific data such as a machine serial number for identifying a machine can be typically mentioned.

By the way, in the case of a copying machine to which the above-mentioned prior art example is applied, it is necessary to store the machine manufacturing number of the copying machine, and at the time of assembling and manufacturing the copying machine, the final manufacturing It is necessary to enter the machine serial number at the process stage. The input method is performed in a special mode such as a service mode or a simulation mode in the operation section of the machine.

That is, although the copying machine main body in which the scanner section and the printer section are incorporated usually has a backup memory powered by a battery, the machine serial number is stored in the backup memory together with other setting data to be backed up. Is set. This machine manufacturing number setting operation is performed by the assembly coordinator at the manufacturing factory.
In the market, a service person puts the copying machine in a service mode or a simulation mode.

[0008]

However, as for the input method, the operating method, the setting method of the machine serial number, etc. in the special mode as described above, the explanation is described in the service manual or the like. Since anyone can easily perform the input operation just by looking at, the machine serial number stored in the backup memory of the copying machine can be changed. Therefore, there is a problem that the backed up data has no meaning as data (here, the machine serial number) stored for specifying the machine to be printed on the copy output.

In order to solve such a problem, it may be possible to set a special service mode used for storing specific data as a service mode by software. In this case, too, Since a manual for each service person is required, it is not possible to provide a drastic solution because the data can be changed by obtaining the manual.

Further, this kind of special service mode is
It may be possible to control the machine so that it can operate only once after the copying machine is completed.However, if this is done, it will not be possible to respond when the machine serial number needs to be re-entered due to reasons such as the assembly process. It is possible and can be said to be an infeasible measure in practice.

The present invention has been made in view of the above problems, and in order to identify the copying machine and the date and time when a copy-prohibited object such as a banknote was copied, those data are stored. It is an object of the present invention to provide a copier that can be combined with a copied image and printed on a sheet, in which the copier and the data for specifying the copying date and time cannot be changed.

[0012]

In order to achieve the above object, the first technical means of the present invention makes it difficult to visually recognize the specific data for specifying the copying machine, the date and the time when the copying of the original image was executed. An image processing apparatus capable of being combined with the copy image data of the original image as data and outputting to the printer unit of the copying machine main body, and a data input capable of inputting the specific data and transferring the data to the copying machine main body. Equipment and
This data input device can be connected to and separated from the main body of the copying machine.

On the other hand, when a data input device is connected to the main body of the copying machine, a connection recognizing means for recognizing that the connection is completed and that the connected device is the data input device,
Data storage means for storing the specific data transferred from the data input device to the copying machine main body only when the device connected to the copying machine main body is recognized as the data input device.

According to the second technical means of the present invention, an image processing apparatus having the same structure as the image processing apparatus of the first technical means and a data input connectable to and separable from the main body of the copying machine. And a permitting device.

On the other hand, when the data input permission device is connected to the main body of the copying machine, the connection recognition means for recognizing the completion of the connection and the connected device is the data input permission device, and the data. Data input means for inputting,
Control means for controlling the data input means to operate only when a device connected to the main body of the copying machine is recognized as a data input permission device, and data storage for storing specific data input by the data input means. And means are provided.

[0016]

According to the first technical means of the present invention, the specific data for specifying the copying machine, date and time can be inputted only from the data input device which can be connected to and separated from the copying machine main body. Controlled. Therefore, if a limited number of data input devices are manufactured by a manufacturer or the like and they are strictly controlled, intentional rewriting of specific data can be reliably prevented.

In this case, when the data input device is connected to the main body of the copying machine, the connection recognition means recognizes that the connection of the device is completed and that the connected device is the data input device. After the recognition process is completed, when the data is input to the data input device, the specific data input to the copying machine main body is transferred from the device. The transferred specific data is written in the data storage means. However, if the device connected by the connection recognition means is not recognized as the data input device, the specific data is not written. After the specific data is input to the copying machine body in this way, the data input device is removed.

According to the second technical means of the present invention, the copying machine, the date and time, etc. are specified only when the data input permission device that can be connected to and separated from the copying machine body is connected. The process of inputting specific data is controlled to operate. Also in this case, if the number of data input permission devices is limited and strictly controlled, the intentional rewriting of specific data can be reliably prevented.

In this case, when the data input permission device is connected to the main body of the copying machine, the connection recognition means recognizes the completion of the connection of the device and that the connected device is the data input device. When the recognition process is completed, the operation of the control means permits the input operation of the specific data by the data input means, and the specific data can be written in the data storage means. Further, after the writing of the specific data is completed, the data input device is removed.

In this figure, 8 is a casing that constitutes the outer shell of the copying machine main body, 9 is a document table, 10 is a photosensitive drum disposed in the casing 8, and 11 is an exposure optical system of the photosensitive drum 10. It is a laser scanner unit. In addition, around the photosensitive drum 10, a main charger 12 including a corona discharger, a developing unit 13, a transfer drum 14,
The cleaning unit 15 has the photosensitive drum 1 in that order.
It is arranged in the rotational direction of 0. Further, 16 is a paper feeding unit, and 17 is a fixing unit.

The document table 9 is provided with a contact glass 18 arranged on the upper surface of the housing 8 and a document holder 19 provided on the contact glass 18 so as to be openable and closable. 20 is a scanning optical system for scanning the original image, 21 is a condenser lens,
22 is a CCD sensor that functions as a light receiving element,
These configure the scanner unit 5 described above.

Now, the document M placed on the contact glass 18 so as to be pressed by the document retainer 13.
Image is scanned by the scanning optical system 20 of the scanner unit 5, and the image information is obtained by using the light as a medium and the condensing lens 2
1 is led to the CCD sensor 22, where it is converted into an electric signal, and then the image processing device 2 performs signal processing. Thereafter, the image processing apparatus 2 supplies the original image data to the laser scanner unit 11. The signal processing in the image processing device 2 will be described later.

On the other hand, while the photosensitive drum 10 is rotating,
After the surface thereof is charged by the corona discharge operation of the main charger 12, the original image is drawn as an electrostatic latent image on the charged surface of the photoconductor drum 10 by the laser scanner unit 11, and this electrostatic latent image is then drawn. Then, the developing unit 13 adheres the charged toner to form a toner image of the original image.

The developing unit 13 has a magenta toner and an M developing device 23M for developing with the toner, and a C developing device 23 with a cyan toner for developing with the toner.
A Y developing device 23Y having C and yellow toners for developing with the toner, and a BK developing device 23BK having black toner for developing with the toner move up and down on a moving body 24 that moves vertically. Laser beams L emitted from the laser scanner unit 11 that are sequentially attached to the
According to the color image data of the latent image writing by B, the image is selectively placed at the developing position facing the photoconductor drum 10.

To form a full-color image during this development, first, an electrostatic latent image is formed on the surface of the photosensitive drum 10 by the laser beam LB emitted from the laser scanner unit 11 based on the magenta color image data. Then, the latent image is developed by the M developing device 23M.

By the way, the paper feeding section 16 is loaded with a plurality of paper feeding cassettes 25 containing papers of various sizes, and a single-leaf paper is fed from the paper feeding cassettes 25 selected alternatively. It is supplied to the transfer drum 14 through the paper path 26. Then, the image on the surface of the photoconductor drum 10 developed with the magenta toner is transferred onto a sheet wound around the surface of the transfer drum 14. Even after the magenta image is transferred, this sheet is held in a state of being wound around the surface of the transfer drum 14 and is used for the next image transfer.

Photosensitive drum 1 on which magenta transfer is completed
The toner remaining on the surface of No. 0 is cleaning unit 15
Is wiped off together with dust and the like adhering to the surface of the drum, and is further neutralized when passing through a neutralization section (not shown) disposed between the cleaning unit 15 and the main charger 12, and then again the main charger. The surface of the photoconductor drum 10 is exposed by the laser beam LB that is charged by 12 and performs the latent image writing operation based on the cyan color image data.

The electrostatic latent image corresponding to the cyan image formed by this exposure is also developed by the C developing device 23C in the same manner as when forming the magenta image. At this time C
The developing device 23C is provided at a position facing the photoconductor drum 10 instead of the M developing device 23M. The image on the photosensitive drum 10 developed with this cyan toner is
The magenta image is first transferred and formed, and then transferred onto the paper held on the surface of the transfer drum 14.

In this way, on the paper on which the magenta and cyan toner images have been formed, the yellow and black images are further processed in the same manner as the above-described magenta and cyan image forming and transfer processes. Is transferred, and finally a full-color duplicate image that is faithful to the original image is formed. After that, the sheet on which the full-color image is formed is separated from the transfer drum 14, and then is conveyed to the fixing unit 17 by the sheet conveying unit 27 and is heated and pressed by the fixing unit 17, whereby the toner image is fixed on the sheet. Then, it is finally discharged from the housing 8.

The image processing apparatus 2 is constructed so that the machine serial number, which is the specific data, can be combined with the copy image data of the original image and output to the printer section 6 of the copying machine body 1, and the scanner section 5 can be used. Input processing circuit 28, a black generation circuit 29, a character adaptation processing circuit 30, a color correction circuit 31, a selector 32, a filter processing circuit 33, a zoom device 34, a halftone processing, a synthesizing circuit 35, an output processing circuit. 36, a pattern generation unit 37, and a CPU 39 that controls these units through a data address 38.

The scanner section 5 separates the image data read from the original document into three primary color data of light, and at the same time, these three primary color data of toner M (magenta), C (cyan),
Convert to Y (yellow). The input processing circuit 28 performs processing such as frequency conversion on the three primary color data M, C, and Y. The black data BK is generated by the black generation circuit 29 based on the image data M, C, and Y that have been subjected to this processing. The image data in which the black data BK is generated is subjected to character enhancement processing by the character adaptation processing circuit 30, and then color correction is performed in accordance with the toner by the color correction circuit 31.

The selector 32 uses four color data M, C, Y,
The BKs are selected one by one and given to the filter processing circuit 33. The selection is not particularly limited to this.
The order is M, C, Y, BK. The selected image data is enlarged / reduced by the zoom device 34 through the filter processing circuit 33, subjected to halftone processing and halftone processing by the synthesizing circuit 35, and then output processing circuit 36 outputs a video signal (pulse).
Is output as.

In the image processing apparatus 2, the selector 32 supplies the image data to the filter processing circuit 33 only for each color. Therefore, as described above, the image reading operation by the scanner unit 5 is performed four times for one image, and the processing of each unit illustrated in FIG.
(One for M, one for C, one for Y, and one for BK). Similarly, the printer unit 6 which operates by the output of the output processing circuit 36 also performs development and printing for each color.

In the above-mentioned configuration, in the present embodiment, the machine manufacturing number is used as data for specifying the copying machine that has copied the original image by the structure described below, and the machine manufacturing number is the machine manufacturing number. The control method that can be input only from the number input device 3 is adopted. Further, the machine manufacturing number input device 3 is limited in the number of products manufactured,
And they should be strictly controlled.

The pattern generator 37 provided in the image processing apparatus 2 uses the machine-specific data (machine serial number in this embodiment) as the original image data in order to identify and manage the copying machine in which the original copy was made. It is added on top. The added data is not easily read by the naked eye when printed on a sheet as a copy image and cannot be easily read, but can be read and recognized by a separately prepared scanner or the like after the copy image is output. A pattern according to a predetermined rule is used.

When the copying operation is started in the copying machine main body 1, the pattern generating section 37 converts the additional data,
After the additional pattern is generated, the additional pattern is output to the halftone processing / synthesizing circuit 35. The halftone processing / combining circuit 35 combines the additional pattern with the original image data, and the combined image data is output to the printer unit 6 via the output processing circuit 36.

In this embodiment, the machine manufacturing number can be set in the pattern generating section 37 by the CPU 40 of the operating section 4 of the copying machine main body 1, the backup memory 7 and the machine manufacturing number input device 3. The machine manufacturing number backed up in 4 is transmitted from the operation unit CPU 40 to the image processing apparatus CPU 39, and the image processing apparatus CPU
From 39 to the data address 38, the pattern generator 3
7 is set as additional data.

That is, the machine manufacturing number input device 3
Is configured so that a machine serial number, which is specific data, can be input, and has a function of transferring the input data to the copying machine main body 1. It is configured to be separable, and the control operation of the built-in CPU 41 makes it possible to input and transfer the machine serial number only when it is connected to the operation unit 4 of the copying machine main body 1. There is.

The machine serial number input device 3, as shown in FIG. 3, for example, has a machine serial number input operation section 42 consisting of a keyboard provided with a numeric keypad and a plurality of function keys with alphabets and the like. And a display panel 43 for displaying data. Although the input device 3 is driven by the power source of the copying machine main body 1, it is not limited to this, and the device itself may be provided with an independent power source.

On the other hand, the operation unit CPU 40 has a connection recognition function for recognizing that the machine manufacturing number input device 3 is connected to the operation unit 4 and that the connected device is the input device 3. Therefore, only when the device connected to the copying machine main body 1 is recognized as the machine manufacturing number input device 3, the machine manufacturing number transferred from the machine manufacturing number input device 3 to the copying machine main body 1 is stored in the backup memory 7. It is designed to work like a store.

Next, the procedure for inputting the machine serial number will be described. First, after confirming the power-off state of the copying machine main body 1, the machine serial number input device 3 is connected to the operation section 4, and after that, Turn on the power of the copying machine main body 1. After that, the operation unit CPU 40 performs the connection confirmation processing of the machine manufacturing number input device 3 in the following procedure.

First, the operation unit CPU 40 transmits a connection confirmation response request command and a device code, and waits for a response from the machine serial number input device 3. Machine serial number input device CPU
Upon receiving the connection confirmation response request command and the device code, 41 transmits the connection confirmation recognition command and the device code to the operation unit 4. The operation unit CPU 40 that has received this connection confirmation recognition command and the device code compares the device code transmitted by the operation unit itself, and if they match, recognizes the connection of the device 3.

If there is no response from the machine serial number input device 3 to the device code transmitted from the operation unit 4 in advance after waiting for a predetermined time, the connection confirmation response request command and the device code are again sent. It transmits and waits again for a response from the machine serial number input device 3. If there is still no response after repeating this process several times, it is recognized that the device is not connected.

When the connection of the machine serial number input device 3 to the operation unit 4 of the copying machine main body 1 is completed, the machine serial number is input by operating the input operation unit 42 of the input device 3. This input data is displayed on the display panel 43 and is temporarily stored in the machine manufacturing number input device CPU 41. When the data input is completed, the input data displayed on the display panel 43 is confirmed, and a predetermined key of the input operation unit 42 is pressed, so that the CPU 41 operates the operation unit CPU 40.
Machine manufacturing number data is transferred to.

The transferred machine manufacturing number data is stored in the operation unit C.
It is written in the backup memory 7 through the PU 40. However, when the operation unit 4 does not recognize the connected device as the machine manufacturing number input device 3 at the stage of the recognition operation of the machine manufacturing number input device 3 described above, the operation unit CPU 40 causes the backup memory 7 to operate. Do not write the machine serial number data to. When it is recognized that the writing of the machine serial number data is completed, the machine serial number input device 3
Is removed from the operation unit 4.

As described above, in this embodiment, the machine serial number for identifying the copying machine is connected to the copying machine main body 1,
It is controlled so that it can be input only from the separable machine manufacturing number input device 3, and the input device 3
Since a limited number of them are manufactured and strictly controlled, intentional rewriting of the machine serial number is reliably prevented.

FIG. 4 shows the electrical construction of another embodiment of the present invention. In the present embodiment, parts having the same configurations and operations as those of the previous embodiment are designated by the same reference numerals, and the description thereof will be omitted to avoid duplication. In this embodiment,
In place of the machine manufacturing number input device 3 of the above embodiment, a machine manufacturing number input permission device 44 as a data input permission device is provided. The machine manufacturing number input permission device 44 is configured to be connectable to and detachable from the copying machine body 1.
By the control operation of the built-in CPU 45, a response operation of connection confirmation with the operation unit 4 of the copying machine main body 1 is performed.

On the other hand, when the machine manufacturing number input permission device 44 is connected to the operation unit 4, the operation unit CPU 40 completes the connection and recognizes that the connected device is the input permission device 44. Only when the device connected to the copying machine main body 1 is recognized as the machine serial number input permission device 44, the machine serial number can be input by the keyboard (not shown) of the operation unit 4 as the data input means. The input machine manufacturing number can be stored in the backup memory 7.

Next, the procedure for inputting the machine serial number will be described. First, the power source of the copying machine main body 1 is turned off, and the machine serial number input permission device 44 is connected to the operation unit 4, and thereafter, the copying machine main body. Turn on the power of 1. Thereafter, the operation unit CPU 40 causes the machine serial number input permission device 44
The connection confirmation processing of the machine serial number input device 3 of the above-mentioned embodiment
The connection is made in the same way.

That is, the operation unit CPU 40 transmits a connection confirmation response request command and a device code, and waits for a response from the machine manufacturing number input permission device 44. Upon receiving the connection confirmation response request command and the device code, the machine manufacturing number input device CPU 41 transmits the connection confirmation recognition command and the device code to the operation unit 4. The operation unit CPU 40 receiving the connection confirmation recognition command and the device code compares the device code transmitted by the operation unit itself, and if they match, recognizes the connection of the device 44. If there is no response even after repeatedly transmitting the connection confirmation response request command and the device code, it is recognized that the device 44 is not connected.

Device 4 for permitting input of machine serial number to operation unit 4
4 is recognized, the operation unit CPU 40 causes the operation unit 4 to operate.
Allow activation of the method of entering the machine serial number in. That is, by operating the keyboard of the operation unit 4 at this time, the machine manufacturing number can be input. This input data is written in the backup memory 7 through the operation unit CPU 40.

However, when the operation unit 4 does not recognize that the connected device is the machine manufacturing number input permission device 44 at the stage of the device recognition operation described above, the operation unit CP
U40 does not write the machine serial number data to the backup memory 7. When it is recognized that the writing of the machine serial number data is completed, the machine serial number input permission device 44
Is removed from the operation unit 4.

The machine serial number written in the backup memory 7 is transferred from the operation unit CPU 40 to the image processing apparatus CPU.
39, and is set as additional data in the pattern generating section 37 from the image processing apparatus CPU 39 through the data address 38. The machine serial number input permission device 44 of the present embodiment is driven by the power source of the copying machine main body 1, but it is not limited to this, and the device itself may be provided with an independent power source.

As described above, in this embodiment, the machine serial number for identifying the copying machine is connected to the copying machine main body 1,
Only when the separable machine serial number input permission device 44 is connected, the machine serial number input process is controlled to operate, and the input permission device 44 is manufactured in a limited number. In addition, since it is strictly controlled, the intentional rewriting of the machine serial number is surely prevented.

In each of the above embodiments, the machine serial number is stored in the backup memory 7 for the data input to the operation unit 4, but in the present invention, the machine serial number for identifying other machines is used. You may make it provide the part to memorize separately separately. Further, the specific data is not limited to the machine serial number, and in addition, the clock built in the copying machine main body 1 or the machine serial number input device 3 is used to use the copy date and time as the specific data, or the copy date and time. And the machine manufacturing number may be written together.

Furthermore, the present invention is applied to a copying machine having a recognition processing function for determining whether or not a document image is a copy prohibition pattern such as a bill, and based on the result of determination of the document image pattern, the document image becomes a copy prohibition pattern. Only when such a case is performed, the pattern generation unit 37 may be configured to output specific data such as a machine manufacturing number.

[0058]

As described above, according to the first aspect of the present invention, the specific data for specifying the copying machine, date and time, etc. can be obtained only from the data input device connectable to and separable from the copying machine main body. Since the data input device is configured to be controlled so that it cannot be input, the number of data input devices is limited by the manufacturer, etc., and by strictly managing them, it is possible to ensure the intentional rewriting of specific data. Can be prevented.

Further, according to claim 2, an input process of specific data for specifying the copying machine, date and time, etc., only when the data input permission device that can be connected to and separated from the copying machine main body is connected. Are configured to be controlled so as to operate, and therefore, as in the case of claim 1, by limiting the number of data input permission devices and strictly managing them, specific data Intentional rewriting can be surely prevented.

As described above, according to the present invention, the means for inputting the specific data for specifying the copying machine and the date and time when the copy of the original image is executed is a special device which can be used only for that purpose, and Since the input means can be operated only when the special device is connected, it is impossible to intentionally change the specific data by strictly managing the special device.

Therefore, for example, even when a bill or the like is copied and abused, by detecting the specific data recorded in the copy-prohibited object with a scanner or the like, the copy-prohibited object is detected by any machine or at any time. Whether or not it was copied on the date and time can be surely recognized, which greatly contributes to the prevention of crimes such as banknote forgery.
