Description

  The present invention relates to an image processing apparatus capable of facsimile communication and network communication.

  Conventionally, when a certificate such as a resident's card or a seal certificate issued by a public institution such as a government office is transmitted to a terminal in a branch office or a branch office, it is generally transmitted by facsimile (for example, , See Patent Document 1).

  However, in order to prevent falsification and copying of certificates issued by public institutions, falsification prevention printing is performed so that hidden characters such as warning marks “invalid” or “copying” appear on the copy when copied. It is common. In the tamper-proof printing, the image is fine and the compression rate is low, so it takes time for facsimile transmission. Therefore, it is common to remove tamper-proof printing and send it to the other party.

  Under such circumstances, in the open network environment such as the Internet, various document data are being exchanged and commercial transactions are being carried out, and it is predicted that there will be various forms in the future. Yes.

FIG. 2 shows functional blocks of the image processing device 2 and the control device 3.
As shown in FIG. 2, the control device 3 includes a certificate editing / issue management unit 31 that manages editing of public certificates and issuance of public certificates. The certificate editing / issuance management unit 31 performs editing of a public certificate, additional writing of a certificate, composition of a background pattern image, and the like. The certificate editing / issuance management unit 31 manages the issuance of the edited public certificate and selects a line for outputting the edited public certificate. The control device 3 is connected to a network line, and the image processing device 2 is connected to a public telephone line network. The certificate editing / issuance management unit 31 is provided with a table for determining the line to which the output destination image forming apparatus 4 is connected. A fax number is registered in the image forming apparatus 4 connected to the public telephone line network, and an IP address is registered in the image forming apparatus 4 connected to the network line. The certificate editing / issuance management unit 31 refers to this table and selects a line for outputting the edited public certificate.

Further, the control device 3 includes a scanner I / F 32, a local print unit 33, a FAX function unit 34, and a remote print unit 35. The scanner I / F 32 reads an image scanned and input by the image processing apparatus 2. If the public certificate is not digitized, the certificate written on the paper is read by the scanner of the image processing apparatus 2, and the read image is processed by the certificate editing / issue management unit 31.
The local print unit 33 is a printer driver for printing the edited public certificate with the image processing apparatus 2. The FAX function unit 34 is an interface unit for transmitting the edited public certificate using the facsimile function of the image processing apparatus 2. The remote print unit 35 is a communication unit for transmitting the edited public certificate via a network line.

  In this embodiment, the control device 3 determines a line that can communicate with the transmission image forming apparatus 4 that is a data transmission destination, and performs control so that data is transmitted using the line. Accordingly, the public certificate can be transmitted to the target image forming apparatus without setting the facsimile number or the IP address by the user. Therefore, data can be transmitted without making the user aware of the connection form with the communication destination.

  When the image forming apparatus 4 connected to the network line is selected as the transmission destination, the control apparatus 3 designates the partner image forming apparatus 4 by the IP address, and sends a public certificate from the remote print unit 35 to the network line. Output to. When the image forming apparatus 4 connected to the public telephone line network is selected as the transmission destination, the control apparatus 3 notifies the fax number from the FAX function unit 34 to the image processing apparatus 2 and sends the public certificate to the public telephone. Send using the network.

  In addition, if a public certificate with a tamper-proof image is transmitted to the public telephone line network, the line is held for a long time. Therefore, when the controller 3 outputs the public certificate to the public telephone line network, The image before the composition of the tamper-proof image is output.

  The tamper-proof printing is a print of watermark characters for preventing tampering as shown in FIG. 3 (A). When an image subjected to tamper-proof printing is copied, tamper-proofing is performed as shown in FIG. 3 (B). Characters are emerging. This printing is composed of a background portion composed of high-density fine dots and a tamper-proof character portion having a lower density than the background portion. When an image with tamper-proof printing is read by a scanner for copying, the background portion cannot be recognized by the scanner but is read in white. For this reason, an image to be printed out is an image in which tamper-proof characters are highlighted.

  Further, if the image printed by the image forming apparatus 4 does not have a falsification-prevented image, forgery is facilitated. Therefore, the image processing apparatus 2 designates a confidential box number and transmits a public certificate when performing facsimile transmission. I do.

  In the storage area of the image memory provided in the image forming apparatus 4, a plurality of confidential reception storage areas are set so that a plurality of users can individually use the confidential communication function. This confidential reception storage area is called a confidential box, and a box number is assigned to each confidential box. When the facsimile communication including the control signal indicating the confidential box number is received, the received image is stored in the confidential box corresponding to the box number indicated by the control signal. Further, the received image transmitted to a predetermined confidential box is set to print an image on a sheet from a predetermined tray. By setting a sheet on which a tamper-proof image has been printed in advance on this predetermined tray, the image forming apparatus 4 can output a public certificate with a tamper-proof image even in facsimile transmission. Can do.

A communication sequence between the image processing apparatus 2 on the transmission side and the image forming apparatus 4 on the reception side will be described with reference to FIG.
First, in the call setting phase, the image processing apparatus 2 on the transmission side outputs a CNG signal (calling signal: calling tone), and the image forming apparatus 4 on the reception side receives this signal and receives the called terminal identification signal. (CED signal) is output. Following the called terminal identification signal (CED signal), an NSF signal (non-standard function identification signal), CSI signal (called terminal identification signal), and DIS signal (digital identification signal) are output from the image forming apparatus 4 on the receiving side. The The image processing apparatus 2 can determine whether or not the receiver is an apparatus capable of receiving a confidential box based on the received NSF signal.

Next, the image processing apparatus 2 transmits an NSS signal (non-standard function setting signal), TSI (transmission terminal identification signal), and DCS signal (digital command signal) to the image forming apparatus 4. When it is determined that the image forming apparatus 4 on the receiving side has the function of receiving a confidential box, the image processing apparatus 2 inserts the number of the confidential box instructed from the control apparatus 3 into the NSS signal, and enters the image forming apparatus 4. Notice.
Next, the image processing apparatus 2 transmits a TCF (training check) signal and receives a CFR (reception preparation confirmation) signal from the image forming apparatus 4, thereby completing message transmission preparation. Thereafter, the image is transmitted from the image processing apparatus 2 to the image forming apparatus 4.
When the image transmission is completed, an EOP (end of procedure) signal is output from the image processing apparatus 2 to the image forming apparatus 4. The image forming apparatus 4 on the receiving side outputs an MCF (message confirmation) signal, and communication is terminated when a DCN (disconnect command) signal is sent from the image processing apparatus 2.

  The image forming apparatus 4 superimposes the background pattern image registered in the confidential box on the received image according to the confidential box number designated from the image processing apparatus 2 on the transmission side, and discharges it from the registered tray. .

Next, the processing procedure of the image processing apparatus 2 will be described with reference to the flowchart shown in FIG. Here, a flow will be described in which a transmission destination is designated from the operation panel of the control device 3, a public certificate is acquired from the host device 1, and the public certificate is output to the designated image forming device 4.
When the application form for the public certificate is transmitted via a facsimile or a network, the operator of the image processing apparatus 2 operates the control apparatus 3 to access the host apparatus 1 to request the requested public certificate. An original document is acquired (step S1). Next, the control device 3 takes out only a necessary part from the original in accordance with the setting of the operation unit, and performs image processing for adding an authentication text (step S2). As shown in FIG. 3, the authentication text is a text proving that the copy of the public certificate is indeed a copy of the original certificate.

Next, the control device 3 displays an input screen for setting a transmission destination on the display and waits for a setting from the user. FIG. 6 shows a display example displayed on the display. Only the installation location of the image forming apparatus 4 is shown on the display, and information such as whether the image forming apparatus 4 and the image processing apparatus 2 are connected by a network line or a public telephone line is not displayed. .
When the transmission destination is set, the control device 3 selects a method for transmitting the public certificate to the designated image forming device 4 with reference to the table. If the IP address of the image forming device 4 is registered in the corresponding table and it is determined that network communication is possible (step S3 / YES), the control device 3 combines the tamper-proof image with the public certificate (step S5). The synthesized public certificate is output to the remote print unit 35. When the remote print unit 35 obtains the public certificate with the tamper-proof image and the IP address of the transmission destination from the certificate editing / issue management unit 31, the remote print unit 35 sends the public certificate to the network line with the obtained IP address as the destination. (Step S6).

  If the fax number of the image forming apparatus 4 is registered in the table (step S3 / NO), the official certificate is output to the FAX function unit 34 without combining the falsification-prevented image. The FAX function unit 34 designates the confidential box number and transmits it by facsimile to the other party (step S4).

  As described above, according to the present embodiment, even if a line used for communication differs depending on a transmission destination, the user can automatically transmit without selecting a transmission method. Therefore, it is possible to reduce time and effort required for the user's operation.

  The above-described embodiment is a public embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention.
