The cursor key 7l is used when moving the selection of items on the screen displayed on the liquid crystal display device 7j.

  The operation display unit 7 is also provided with a buzzer 8 (not shown) for notifying the user of a warning sound or the like.

  Further, as shown in FIG. 4A, as system initial setting information, basic settings for registering basic setting information of the network compatible MFP MFP, paper settings for registering usable paper, etc. File transfer destination settings for registering file transfer destinations and administrator setting information for registering administrator setting information are provided, and are stored in the parameter memory 3, for example. Each setting information is registered by appropriately operating the operation display unit 7 by the user.

  For example, as shown in FIG. 5B, the administrator setting information is used to set whether to perform log transfer and whether to perform unauthorized copy suppression. Includes illegal copy suppression information.

  In the case where “(suppress unauthorized copying)” is registered in the unauthorized copy suppression information, the background pattern recognition processing of the background pattern recognition processing unit 15 is applied to the image data read by the scanner 5, and A check is performed to determine whether or not a predetermined tint block pattern is included. If it is determined that a predetermined copy-forgery-inhibited pattern pattern is included, predetermined invalidation processing is performed and invalidated image data (described later) is output. For example, during a copying operation, the invalidation image is recorded and output as a copy, and when the scan-to-email function is designated, invalidation image data is sent to the designated email address. Send the attached email. In the case of the scan-to-email function, a warning message notifying that a document set to inhibit unauthorized copying has been read can be included in the body information.

  For example, as shown in FIG. 5A, the tint block pattern is recorded as a random dot-like isolated point pattern on a sheet of paper. In the present embodiment, when setting to register to suppress unauthorized copying is performed, when an image of a document sheet on which such a copy-forgery-inhibited pattern is printed is read as shown in FIG. The scanned image is converted into invalidated image data and output. For example, during a copying operation, a copied image as shown in FIG. In the case of a scan-to-email operation, image data as shown in FIG. 5B is transmitted as read data.

  FIG. 6 shows an example of the background pattern recognition processing unit 15.

  First, the copy-forgery-inhibited pattern recognition processing unit 15 processes binarized image data RD obtained by binarizing image data obtained by reading with the scanner 5. The isolated dot detection unit 15a divides the input binarized image data RD into rectangular block units (see FIG. 7A) in which the main scanning direction is d dots and the sub-scanning direction is 1 dot. The block detects whether an isolated point is included, and its output signal is output to the phase information storage unit 15b.

  As shown in FIG. 7B, the phase information storage unit 15b divides a region (the processing unit (pattern matching block) of the next pattern matching unit 15c) in which the main scanning direction is B block and the sub scanning direction is L block. For each block included in each region, it is checked whether the isolated dot detection unit 15a has detected an isolated point, and the processing result is output to the pattern matching unit 15c.

  Based on the output result of the phase information storage unit 15b, the pattern matching unit 15c checks the arrangement mode of the blocks in which isolated points are detected among the blocks included in the processing unit area, and the pre-registered background pattern Whether or not the pattern matches is detected, and the detection result is output to the background pattern detection unit 15d.

  For example, the background pattern detection unit 15d monitors the output of the pattern matching unit 15c for each line of the pattern matching block, and determines that a background pattern has been recorded when a predetermined number or more of background patterns are detected. Then, the determination result is output as a signal SS.

  FIG. 8 shows an example of processing when the user operates the operation display unit 7 to register unauthorized copy suppression information.

  First, when the user selects a system initial setting (process 101), a predetermined system initial setting screen is displayed (process 102), and when the user selects an administrator setting screen (process 103), an authentication code is input. Is requested (step 104), and the input authentication code is compared with a pre-registered value (not shown) to determine whether or not they match (determination 105). When the result of determination 105 is NO, the process returns to process 104 and the authentication code is input again.

  When the result of determination 105 is YES, an administrator screen as shown in FIG. 9 is displayed (process 106), and when the user selects unauthorized copy suppression (process 107), unauthorized copy suppression as shown in FIG. 10 is performed. A selection screen is displayed (process 108).

  Since the user selects “Yes / No” from the unauthorized copy suppression selection screen (process 109), the selected content is registered in the unauthorized copy suppression information of the administrator setting information of the system initial setting information (process 110). ).

  In this embodiment, when the unauthorized copy suppression information is set to “Yes”, the above-described copy-forgery-inhibited pattern pattern recognition operation is performed every time the document reading operation is performed, and unauthorized copy suppression is set to the scanned document. Find out if it is.

  As described above, for a manuscript for which unauthorized copy suppression is set, the printed image of the invalidated image data is output as a copied material in the copying operation, and the invalidated image data is read and scanned in the scan-to-email operation. Send to the email address specified as data.

  At the same time, a strong attention sound is generated using the buzzer 8. This ringing operation is performed on a page-by-page basis. If all of the continuously scanned documents are set to suppress unauthorized copying, the sound of strong attention is sounded when unauthorized copying suppression is recognized when reading the subsequent pages. If it is in operation, once the strong attention sound sounding operation is stopped, a new strong attention sound sounding operation is performed.

  In this way, even when read originals set with illegal copy suppression are consecutive, alerts using the buzzer 8 are appropriately issued for each page, and the reading user and other users (third parties) around it. ), And the effect of psychological copy suppression can be enhanced.

  FIG. 11 shows an example of a main part of processing of the strong attention sound ringing operation of the buzzer 8.

  When the copy-forgery-inhibited pattern is recognized by the reading operation for each original, a buzzer sounding request with strong caution is generated. At this time, it is determined whether or not the strong attention sound is already operating (decision 201). When the result of determination 201 is YES during the operation of the strong attention sound, the strong attention sound is canceled and a buzzer counter (described later) is initialized (processing 202).

  In this way, a strong attention sound start process is performed in a state where there is no ringing process during operation (process 203).

  Further, when the strong attention sound is not operating and the result of determination 201 is NO, it is determined whether another warning sound is operating (determination 204). When another warning sound is in operation and the result of determination 204 is YES, the warning sound is canceled and the buzzer counter is initialized (process 205). Next, the process proceeds to process 203, where a strong attention sound start process is performed.

  Further, when the result of determination 204 is NO, the process proceeds to process 203, and a strong attention sound start process is performed.

  Here, the buzzer ringing start process is realized by setting a buzzer counter corresponding to the instructed buzzer pattern (strong attention sound, warning sound, operation sound, etc.) as shown in FIG. 301-process 306). As the set of buzzer counters in the processes 302, 304, and 306, the number of buzzers, the buzzer on time, the buzzer off time, the buzzer request level, the buzzer volume, and the like are performed.

  Thus, when the buzzer counter is set by the buzzer ringing start process, the buzzer 8 is ringed according to the contents of the set buzzer counter.

  In this way, by processing only the last strong attention sound when recognizing a tint block pattern with a plurality of originals, it is possible to prevent the buzzer from continuing to sound after all reading processes are completed and the user disappears. it can.

  FIG. 13 shows an example of a buzzer ring reservation registration process when a tint block pattern is recognized by a plurality of documents.

  First, when a copy-forgery-inhibited pattern is recognized by a reading operation for each document, a buzzer sounding request with strong caution is generated. At this time, it is determined whether or not the strong attention sound is already operating (decision 401). When the strong attention sound is in operation and the result of determination 401 is YES, reservation registration of the strong attention sound is performed (processing 402). Further, when the strong attention sound is not being operated and the result of determination 401 is NO, a strong attention sound start process is performed (process 403).

  FIG. 14 shows an example of the buzzer ring reservation execution process.

  As a premise, reservation monitoring is executed as interrupt processing at a fixed time.

  First, it is determined whether or not the strong attention sound has ended (decision 501). If the strong attention sound has ended (the result of determination 501 is YES), it is determined whether there is a reservation registration for the strong attention sound (decision 502). If there is a reservation registration for a strong attention sound (the result of determination 502 is YES), a start processing for the strong attention sound is performed (processing 503).

  Next, the reservation that has undergone the start process is deleted, and the number of reservations is updated (process 504).

  In addition, when the result of determination 501 is NO and when the result of determination 502 is NO, processes 503 and 504 are not executed.

  In this way, when a tint block pattern is recognized by a plurality of originals, a strong warning sound for the original that has recognized the tint block pattern is sounded to inform the third party of the number of originals prohibited from unauthorized copying.

  FIG. 15 shows an example of a buzzer ringing reservation registration process when another warning occurs.

  A warning buzzer sounding request is generated when the warning factors are complete. At this time, it is determined whether or not the strong attention sound is already operating (decision 601). If a strong attention sound is in operation (the result of determination 601 is YES), a warning sound is registered for reservation (process 602).

  On the other hand, if the strong attention sound is not operating (the result of the determination 601 is NO), a warning sound start process is performed (process 603).

  FIG. 16 shows another example of the buzzer ring reservation execution process.

  As a premise, reservation monitoring is executed as interrupt processing at a fixed time.

  It is determined whether or not the strong attention sound has ended (decision 701). If the strong attention sound has ended (the result of determination 701 is YES), it is determined whether there is a reservation registration for the strong attention sound (determination 702). If there is a reservation registration of the strong attention sound (the result of the determination 702 is YES), the start processing of the strong attention sound is performed (processing 704).

  Then, the reservation for which the start process has been performed is deleted, and the number of reservations is updated (process 704).

  On the other hand, if there is no reservation registration for strong attention sound (the result of determination 702 is NO), it is determined whether there is reservation registration for warning sound (determination 705). If there is a warning sound reservation registration (the result of determination 705 is YES), a warning sound start process is performed (process 706). Then, the process proceeds to process 704, where the reservation for which the start process has been performed is deleted, and the number of reservations is updated.

  In addition, when the result of determination 705 is NO and when the result of determination 701 is NO, this process ends.

  In this way, when a strong warning sound is generated when a background pattern is recognized, even if another warning occurs, the buzzer related to the other warning is sounded after the strong warning sound. The occurrence can be recognized.

  FIG. 17 shows another example of the buzzer ringing reservation registration process when another warning occurs.

  A warning buzzer sounding request is generated when the warning factors are complete. At this time, it is determined whether or not the strong attention sound is already operating (decision 801). If the strong attention sound is being operated (the result of determination 801 is YES), it is determined whether the target warning is not displayed for a certain period of time (decision 802). If it is not displayed for a certain period of time (the result of determination 802 is YES), reservation registration of a warning sound is performed (processing 803). If the result of determination 802 is NO, this process ends.

  On the other hand, if the strong attention sound is not operating (the result of determination 801 is NO), a warning sound start process is performed (process 804).

  In this way, if another warning that is displayed only for a certain time is generated when the strong attention sound when recognizing the copy-forgery-inhibited pattern pattern is generated, the buzzer does not sound after the strong attention sound. Thus, it is possible to avoid a situation in which the warning display and the buzzer are out of timing.

  FIG. 18 shows an example of operation sound processing during the operation of strong attention sound.

  When the operation panel is operated, an operation sound buzzer sounding request is generated. At this time, it is determined whether or not the strong attention sound is already operating (process 901). If the strong attention sound is being operated (the result of determination 901 is YES), processing for the buzzer sounding request is not performed.

  On the other hand, if the strong attention sound is not being operated (the result of determination 901 is NO), the operation sound start process is performed (process 902).

  In this way, when the strong attention sound is generated when the copy-forgery-inhibited pattern is recognized, if the operation panel is operated, the buzzer is not sounded after the strong attention sound. It is possible to avoid a situation in which the timing difference between the panel display and the buzzer occurs.

  In the above description, the case where the present invention is applied to the network compatible MFP MFP has been described. However, the present invention is not limited to other apparatuses having a document reading function, such as a scanner apparatus, a network compatible scanner apparatus (particularly, The same can be applied to a copying machine, a facsimile machine, and a network facsimile machine having a scan-to-email function.
