Output.
The question data creation unit 450 creates question data based on the processing result from the information rewrite processing unit 448 and outputs it to the document tag reading / writing unit 402.

  FIG. 10 is a diagram illustrating the configuration of each information. (A) illustrates the configuration of document information, (B) illustrates the configuration of command information, (C) illustrates user identification information, (D) illustrates the configuration of the question data created by the question data creation unit 450.

As shown in FIG. 10A, the document information includes a document identifier that is an identifier of the document, a user identifier of a user who uses the document (for example, a copy of the document), and usage restrictions for each user. It includes usage limit number information indicating the number of (copy limit) times, usage number information indicating the number of times each user has used the document, and usage time information indicating the time at which each user has used the document.
As shown in FIG. 10B, the command information includes a responder identifier that is an identifier of the command responder 52, a use limit number rewrite command that is a command for rewriting use limit information such as increasing or decreasing the use limit number, and the like. And a usage count reset command which is a command for resetting the usage count.
As shown in FIG. 10C, the user identification information indicates a user identifier that is an identifier of the user of the identification card, and user attribute information that indicates a department and a position to which the user belongs.

As shown in FIG. 10D, the question data includes a writing code, a user identifier, a usage limit number rewriting command, and a usage number reset command.
Note that the instruction information is composed of numerical values representing, for example, the type and number of instructions as a data structure. However, the meaning of the information is a value added to the current use limit number, In some cases, it may be 0, or it may be a value to be subtracted from the current usage count. Further, when the data position prescribes the type of instruction, a structure having only a numerical value may be used.
Further, the command information may include only one of the usage limit number rewriting command or the usage number reset command. In this case, the question data includes only one of the usage limit number rewriting command or the usage number reset command.
The document tag 50 that has received the question data rewrites the use limit number information based on the use limit number rewrite command and resets the use number number to the question data when the use limit number rewrite command is included in the question data. If an instruction is included, the number of times indicated by the usage count information is reset to 0 based on the usage count reset command.

Here, for example, the use limit number (copy limit number) of a document is five times, and the user A has already copied the document five times. However, the document is necessary because it is necessary for an important meeting or the like. Consider the case of copying.
In this case, by using the command responder 52 including the usage limit number rewriting command for increasing the usage limit number, the usage limit number information corresponding to the identifier of the user A stored in the document tag 50 is rewritten, thereby the user A Can copy the document.

In addition, by using the command responder 52 including the usage count reset command, the user A can copy the document by rewriting the usage count information corresponding to the identifier of the user A stored in the document tag 50.
In this case, an increase in the usage limit count may be determined according to the user attribute information.
For example, when the attribute indicated by the user attribute information is a high post, the increment of the usage limit number may be increased (or infinite).
If the usage limit number indicated by the usage limit number information is 0, copying of the document is prohibited.

FIG. 11 is a flowchart showing the processing (S30) of the image forming apparatus 4.
In step 300 (S300), the identification card reading unit 422 reads the user identification information from the identification card 54.
In step 302 (S302), the document tag reading / writing unit 402 reads the document information from the document tag reading / writing unit 402.
In step 304 (S304), the command information acquisition unit 444 determines whether or not the command responder read / write unit 420 has read a command from the command responder 52, and if so, the process proceeds to S306 to read the command. If not, the process proceeds to S330.

In step 306 (S306), the command analysis unit 446 determines whether or not a usage count reset command is included. If so, the process proceeds to S308, and if not, the process proceeds to S310.
In step 308 (S308), the information rewrite processing unit 448 performs processing for adding a usage count reset command for resetting the usage count corresponding to the user identifier read from the identification card to the question data.

In step 310 (S310), the command analysis unit 446 determines whether or not the usage limit number rewriting command is included. If so, the process proceeds to S312; otherwise, the process proceeds to S314.
In step 312 (S312), the information rewrite processing unit 448 performs processing for adding a use limit number rewrite command for rewriting the use limit number corresponding to the user identifier read from the identification card to the question data.

In step 314 (S314), the question data creation unit 450 performs a process of adding a writing code to the question data to create question data.
In step 316 (S316), the question data creation unit 450 transmits the question data to the document tag reading / writing unit 402, and the document tag reading / writing unit 402 transmits the question data to the document tag 50. .
The document tag 50 that has received the question data rewrites the document information based on a command included in the question data.

In step 330 (S330), the control device 21 determines whether or not the document information read from the document tag 50 includes the user identifier read from the identification card 54. If included, the process proceeds to S332. If not included, the process proceeds to S336.
In step 332 (S332), the control device 21 determines whether or not the copy count (use count) corresponding to the user identifier is less than the limit count, and if it is less than the limit count, the process proceeds to S340. If so, the process proceeds to S334.
In step 334 (S334), the control device 21 operates the operation unit 410 and the like to issue a warning, and stops the copy operation.
In this case, the command responder 52 may be used to rewrite the information in the document tag 50 and the process may be advanced so as to continue the copying operation.

In step 336 (S336), the control device 21 determines whether or not the user identifier read from the identification card 54 is permitted to copy the document relating to the document tag 50. If not permitted, the process proceeds to S334. If it is permitted, the process proceeds to S338.
In step 338 (S338), the document tag reading / writing unit 402 performs processing for writing the user identifier read from the identification card 54 and the limit number of times into the document information of the document tag 50.

In step 340 (S340), the document tag reading / writing unit 402 increments the usage count for the user identifier read from the identification card 54 by 1 and performs processing for writing in the document information of the document tag 50.
In step 342 (S342), the control device 21 operates the printing device 406 to perform a copy operation.

Conventionally, when usage restriction information is stored in the document tag 50, the user cannot copy even if there is a situation in which the usage limit information is exceeded and copying is desired.
Even when the document information stored in the document tag 50 can be rewritten, it has been rewritten by a system administrator operating the terminal or the like.
On the other hand, if the command responder 52 is used as in the present embodiment, no operation of the terminal or the like is required when rewriting the document information stored in the document tag 50.
