Description

  The present invention relates to a document printing system, a copying apparatus, a document printing program, a recording medium, and a document printing method for managing a letterhead such as a company name, which is printed outside a sheet of paper on which a document is written.

A letter head such as a company name or a telephone number is printed outside the envelope or letter paper used in the company. For example, in an application program for a word processor, letterhead printing can be realized by header processing or footer processing. However, it is troublesome to set the same letterhead in the header and footer for each application. If there is a change in a part of the article, it will be necessary to change the settings of all applications. Thus, a technique for controlling a printer driver and inputting a unified letterhead or logo has been developed (see Patent Document 1).

FIG. 1 is a block diagram showing a specific example of a document printing system of the present invention.
A computer 11 constituting the document printing system is connected to the network 10. Further, the network 10 is connected to a terminal device 12 for making a letterhead transfer request when printing a document. The terminal device 12 controls the printer 13 to print a document. In addition, although arbitrary terminal devices are connected to the network 10, illustration is omitted. A network printer 14 is also connected to the network 10.

  The computer 11 is provided with a storage device 20 and an arithmetic processing device 30. The storage device 20 stores letterhead data 21, authentication data 22, transfer history data 23, received data 25, and document name letterhead correspondence data 28. The transfer history data 23 includes request source information 24 and letterhead data 21. The received data 25 includes request source information 24, document information 26, and letterhead selection information 27. The document information 26 is acquired as necessary. The arithmetic processing unit 30 includes letterhead data management means 31, authentication processing means 32, data transfer means 33, data editing means 34, time data acquisition means 35, serial number generation means 36, and data selection means 37. Each of these means comprises a computer program that gives a predetermined function to the computer 11.

FIG. 2 is a hardware block diagram of the computer 11.
An internal bus 120 of the computer 11 includes a CPU (Central Processing Unit) 121, a ROM (Read Only Memory) 122, a RAM (Random Access Memory) 123, an HDD (Hard Disk) 124, an input / output interface 125, a network. The interface 126 is connected. A display 132, a keyboard 133, and a mouse 135 are connected to the input / output interface 125. The terminal device 12 is connected to the network interface 126 via the network 10. The above hardware is provided in a generally well-known personal computer. The terminal device 12 has the same configuration except that the printer 13 is connected. Therefore, the overlapping description is omitted.

  The storage device 20 illustrated in FIG. 1 includes a ROM 122, a RAM 123, and an HDD 124. The arithmetic processing unit 30 illustrated in FIG. 1 includes a CPU 121, a ROM 122, a RAM 123, and the like. Various types of information are mainly stored and saved in the HDD 124. The computer program executed by the CPU 121 is stored in the ROM 122 or loaded into the RAM 123 as appropriate.

FIG. 3 is a diagram illustrating a specific configuration of each data stored in the storage device 20.
FIG. 3A is an explanatory diagram of request source information. The request source is the terminal device 12 or the network printer 14 that requests transfer of the letterhead data 21 through the network. As illustrated, the request source information 24 includes user identification information 41, a transmission source address 42, and printer identification information 43. This system prevents users from randomly using letterhead data. Therefore, when printing a letterhead on a document, the computer 11 obtains request source information in advance. Therefore, the request source information 24 includes user identification information 41 for specifying a user. In addition, a source address 42 is included for transferring letterhead data from the computer 11 by e-mail or the like. The sender address 42 may be a mail address or a URL of a storage area for storing data. Further, the request source information 24 may include printer identification information 43 to indicate which printer the document is printed on.

FIG. 3B is an explanatory diagram of a specific example of letterhead data.
The letterhead data 21 is data for printing a letterhead on a document to be printed on the printer 13 by the terminal device 12. The letterhead data 21 includes data such as a logo 51, a company name 52, a telephone number 53, and a FAX number 54. These are image data or character data. Version 55 is data indicating an update history when the letterhead data 21 is updated. The layout data 56 includes information such as in which part of the letterhead the logo 51 and the company name 52 are arranged. With these data, a letterhead having a predetermined configuration can be printed at a designated place of the document, for example, a header or a footer. The data before printing is letterhead data, and the printed data is letterhead data.

  The information marked with * is data generated and added each time the letterhead data 21 is transferred to the request source. If the history of when the letterhead data of which serial number is transferred to which user is left in the transfer history data 23, the user manages the document on which the corresponding letterhead is printed with responsibility. This prevents unauthorized use of the letterhead. For this purpose, for example, identification information 57 is given so that all letterhead data transferred from the computer 11 can be distinguished. Of course, for example, the same identification information may be given in units of documents. When the documents are different, different identification information may be given. The original letterhead data 21 stored in advance in the storage device 20 shown in FIG. 1 does not include identification information. On the other hand, the transfer history data 23 shown in FIG. 1 includes request source information 24 and letterhead data 21. This letterhead data 21 includes identification information 57.

  The transfer history data 23 is used to check whether or not a document on which a certain letterhead data is printed is issued normally, or to which user it is issued. The transfer history data only needs to include at least identification information for identifying the transferred letterhead data. If information such as the transfer date and time and the request source is included, reference and discrimination are facilitated. The transfer history data need only be stored in a state where it can be used by referring to it from the outside, not just storing it. The term “external” means from the outside of a computer such as a server provided with a storage device. Including the case of browsing through the network.

  The identification information 57 is for preventing inadvertent use or illegal use of letterhead data, and may be information that can be distinguished from other letterhead data. For example, when identification information including an issue date and a serial number is individually assigned to all letterhead data to be issued, different identification information is printed on the letterhead of each page printed on one document. On the other hand, the same identification information may be assigned to letterheads of documents printed in a batch, and different identification information may be assigned to each document. The serial number may be rounded as appropriate and become the same number. The identification information 57 may be composed entirely of numerical values, or may include characters and symbols. As will be described later, if the identification information is included in the letterhead as characters or symbols, the letterhead design may be impaired. In this case, it is preferable that the identification information is converted into code image data such as a bar code or a two-dimensional bar code so as to form a letterhead that is unified as a whole.

  The code image data is used for identification and confirmation of letterhead data. The optically readable code image data may be a general bar code, a two-dimensional bar code, or arbitrary image data in which characters and symbols are graphicized. This image data is printed together with the letterhead data. It may be printed on any part of the letterhead.

  Further, the letterhead data 21 can include document information 58. The configuration of the document information 58 will be described with reference to FIG. FIG. 3D is an explanatory diagram of document information. The document information 26 includes, for example, data such as a document name 71, document manager identification information 72, document page number 73, creation date 74, print number 75, and others 76. The document name 71 is a file name of a document for printing the letterhead. The document manager identification information 72 is, for example, a document creator identification code. Alternatively, the user code of the terminal device 12 may be used. The document page number 73 is the number of pages of the entire document. The creation date 74 is the creation date of the document. The number of printed sheets 75 is the number of printed pages that actually include letterhead data. Letterhead data corresponding to the number of printed sheets is supplied. The other portion 76 may optionally include various information related to the document. For example, information specifying a printer used for printing may be included. The document information 26 is information that clarifies the origin of the document. It is effectively used as information for determining what kind of document the letterhead data is provided for. Including document information 26 in the transfer history data 23 ensures management of the letterhead data. In order to distinguish all the letterheads printed on the document, the identification information 57 and the document information 58 can be used as described above. That is, time data, serial number, document name 71, document manager identification information 72, etc. may be used in any combination.

  FIG. 3C is an explanatory diagram of the authentication data 22. The user uses the terminal device 12 with a certain qualification, accesses the computer 11, and receives letterhead data. Therefore, authentication data 22 including user identification information 61 and a password 62 is stored in the storage device 20 of the computer 11. The authentication process is the same as a general computer network login process. When the user identification information 61 is input from the terminal device 12 and the password 62 is input, the computer 11 executes an authentication process.

  The format and structure of the document on which the letterhead is printed are arbitrary. The form and structure of the letterhead are also arbitrary. Any content that can be used in a unified manner by a company, etc., and that clearly identifies the source, etc. It is only necessary to hold the latest unified letterhead data and transfer it to each requester. It is printed at a place other than the body of the paper for printing a document, a margin, or the like. The authentication data is data for confirming the qualification of the user who uses the letterhead, and its format and contents are arbitrary. Since the authentication process of the request source is executed, unauthorized use of the letterhead data can be prevented. In the authentication process, an ID code and a password may be manually input, or an ID card may be used. The letterhead data is updated, for example, when the department name is changed. The update operation may be performed artificially. For update management, it is sufficient to store the latest letterhead data in a storage device and display the result. Further, it may include a process of displaying the letterhead data version, and managing a plurality of types of letterhead data so that they can be selected according to the application. The network may be for a wide area or a closed area.

  The received data 25 shown in FIG. 1 temporarily stores information acquired when a request for transferring letterhead data is received from the requesting terminal device 12. The received data 25 includes document information 26 and letterhead selection information 27 in addition to the request source information 24 depending on the case. When the document information is included in the letterhead data, the document information 26 is received from the request source. When there are a plurality of types of letterhead data 21, letterhead selection information 27 is received from the request source. For example, when the requester knows that several types of letterhead data 21 are prepared in advance, letterhead selection information 27 is received to select one of them. For example, there are a Japanese version and an English version, and a version corresponding to the paper size. The document name can be handled as the letterhead selection information 27. If there is a document name assignment rule, the type of letterhead data is determined according to the document name. Thereby, appropriate letterhead data can be automatically selected using the document name.

  The document name letterhead correspondence data 28 shown in FIG. 3 (e) is data indicating such a correspondence. The corresponding letterhead data serial number 77 can be acquired using the document name 71 as a key. The document name letterhead correspondence data 28 may be any data as long as the information included in the document name is associated with the letterhead data used for the document. The information included in the document name may be the entire document name or a part of the document name. A plurality of types of letterhead data may be properly used according to the nature of the document, for example. The letterhead selection information received from the request source may be information for directly or indirectly selecting one of a plurality of types of letterhead data. Therefore, in addition to information indicating the type of letterhead data, it may be information indicating the category and importance of the document. The data selection means may have a function of performing a predetermined calculation process from the letterhead selection information received from the request source, selecting any letterhead data and transferring it to the request source.

  Next, the arithmetic processing unit 30 shown in FIG. 1 will be described. The letterhead data management means 31 has a function of executing update processing, version management, etc. when various letterhead data 21 are stored in the storage device 20. Such management is performed, and appropriate letterhead data is always provided to the user in the latest state. The authentication processing means 32 has a function of executing authentication processing of the request source when receiving a transfer request for the letterhead data 21 through the network 10. Authentication data 22 is referred to in the authentication process. The data transfer unit 33 has a function of transferring the letterhead data 21 to the request source when the transfer is permitted as a result of the authentication processing by the authentication processing unit 32. The data editing means 34 has a function of executing processing for including document information 26 and the like that clarify the origin of the document in the letterhead data. By analyzing the information contained in this letterhead, it is possible to know the document manager, the author of the document, etc., and the letterhead management is ensured.

  The time data acquisition means 35 has a function of acquiring time data using a system clock. The time data is used to generate the identification information 57. For example, the serial number generating means 36 has a function of counting up each time the letterhead data 21 is transferred to the request source, and assigning serial numbers to all the letterhead data 21. The serial number is also used to generate the identification information 57. When the document information is acquired from the request source, the data selection unit 37 acquires the document name, for example, refers to the document name letterhead correspondence data 28, and selects any corresponding letterhead data 21. And has a function of notifying the data transfer means 33. Upon receiving the notification, the data transfer means 33 transfers the corresponding letterhead data 21 to the request source.

FIG. 4 is an explanatory diagram showing a specific example of a letterhead printed on a document.
As shown in the drawing, a letter head 85 is printed on, for example, a footer portion of a paper 80 on which a document is printed. On this letterhead 85, a logo 81, a company name 82, a telephone number 83, and the like are printed. Further, in this example, the identification information converted into the barcode 84 is printed. If this bar code 84 is, for example, a two-dimensional bar code, it is possible to include not only identification information but also a larger amount of information such as document information. In this example, it is assumed that this document is an important document and copying is not permitted. The information is included in the information indicated by the barcode 84. When the copying apparatus reads the bar code 84, the copying prohibition operation is performed. As shown in FIG. 4, for example, a message such as “copying of this document is prohibited” is displayed on the display 90 of the copying apparatus, and the printing operation of the document is stopped.

FIG. 5 is a block diagram showing a copying apparatus having the document printing prohibition function as described above.
As shown in the figure, the copying apparatus 100 includes an arithmetic processing unit 101, a scanner 104, a print control unit 105, a print engine 106, a display 107, and a storage device 110.

The arithmetic processing unit 101 is provided with information recognition processing means 102 and copy control means 103. The information recognition processing means 102 and the copy control means 103 are composed of computer programs that give predetermined functions to the computer of the copying apparatus. If the network printer 14 shown in FIG. 1 has a copying function, the network printer 14 operates as the copying apparatus 100.

  The scanner 104 reads a document to be copied. This comprises, for example, an image line sensor or a CCD device. The print control unit 105 is a part that executes predetermined processing for supplying print data read by the scanner 104 to the print engine 106. The print engine 106 is a mechanism portion that prints a document to be copied on paper. A display 107 is a display device for operation provided in the copying apparatus 100. These mechanisms are provided in a known copying apparatus and will not be described in further detail.

  The copy prohibition information 111 stored in the storage device 110 is information that can be acquired when the barcode 84 shown in FIG. 4 is read. The copy prohibition information 111 is information indicating that this document is prohibited from being copied. The copy prohibition message 112 is character data corresponding to the message 91 described with reference to FIG. This message is displayed on the display 107. The print data 113 is data for copy printing read by the scanner 104. Temporarily retained for printing operations. The scanner 104 reads a document to be copied. The image data of the letterhead portion is transferred to the information recognition processing means 102. The information recognition processing unit 102 has a function of recognizing the bar code 84 included in the letterhead portion and extracting the copy prohibition information 111. The copy control means 103 has a function of reading a copy prohibition message 112 from the storage device 110 and displaying it on the display 107 when it is determined that the copy prohibition information 111 is included in the letterhead portion. With the functions as described above, the copying apparatus 100 can automatically prohibit document copying according to the contents of the letterhead. Accordingly, the letterhead data can be used for important document management.

FIG. 6 is a specific operation flowchart of the document printing system shown in FIG.
Next, an embodiment of a computer program suitable for controlling the system of the present invention will be described. First, it is assumed that a request for issuing letterhead data 21 is made from the terminal device 12 to the computer 11 through the network 10. In step S11 of FIG. 6, when the computer 11 receives this issue request, the process proceeds to step S12. In step S12, the authentication processing means 32 refers to the authentication data 22. In step S13, authentication is performed using the user identification information 61 and the password 62 sent from the terminal device 12. When this authentication process ends, the process proceeds to step S14.

  In step S14, it is determined whether or not the result of the authentication process is possible, and it is determined whether or not letterhead data transfer is permitted. If the transfer is permitted, the process proceeds to step S15. If transfer is not permitted, the process returns to step S11. In step S15, document information is acquired from the terminal device 12. In step S16, identification information is generated using the time data acquisition means 35 and the serial number generation means 36. In step S17, the letterhead selection information 27 is received. As a result, any letterhead data 21 is selected in step S18. If there is only one type of letterhead data, the processes of steps S17 and S18 are not executed.

  In step S19, processing for converting the identification information included in the letterhead data into a two-dimensional barcode is executed. In step S20, the layout data 56 and the like are adjusted and letterhead data editing processing is performed. That is, after the identification information 57 and the document information 58 are combined and converted into a two-dimensional barcode, print data is generated so that printing can be performed together with a letterhead logo or the like. In step S21, the letterhead data is transferred to the terminal device 12. In step S 22, transfer history data 23 including the transferred letterhead data 21 and request source information 24 is generated and stored in the storage device 20. With the above processing, letterhead data necessary for printing can be transferred to the request source and the record can be left in the storage device 20.

FIG. 7 is an explanatory diagram of a document category acquisition operation using data corresponding to the document name letterhead data.
First, in step S31 in FIG. 7, document information is acquired from the request source. Here, information indicating the category included in the document name can be automatically acquired from the rule for assigning the document name. For example, the letterhead data for Japanese and English can be automatically selected unconditionally. In this embodiment, in step S32, data corresponding to the document name included in the document information is acquired, and the document name letterhead correspondence data 28 is referred to. In step S33, the letterhead reference number 77 is acquired using the document name as a key. As a result, appropriate appropriate letterhead data 21 can be selected and transferred to the request source.

FIG. 8 is an operation flowchart of the copying apparatus shown in FIG.
First, when a document to be copied is placed on the copying apparatus and a copy button (not shown) is pressed, the scanner 104 operates in step S41 in FIG. 8 to read the copied document. In step S42, the information recognition processing unit 102 recognizes information included in the letterhead from the data read by the scanner 104. In step S43, it is determined whether the recognized information includes copy prohibition information. If not included, the process proceeds to step S47 to execute the printing process as it is. If copy prohibition information is included, the process proceeds to step S44, the print job is stopped, and the copy prohibition message 112 is read from the storage device 110 in step S45. In step S46, the message is output and displayed on the display 107. With the above operation, it becomes possible to manage important documents using letterhead.

  Note that the computer program executed by the arithmetic processing unit may be modularized in units illustrated in functional blocks, or may be integrated by combining a plurality of functional blocks. Further, the above computer program may be used by being incorporated into an existing application program. The computer program for realizing the present invention can be recorded on a computer-readable recording medium such as a CD-ROM and installed in an arbitrary information processing apparatus for use.
