Next, the operation of this embodiment will be described.
(Annoying fax countermeasure setting mode)
First, annoying fax countermeasure setting will be described. The mode setting key 61 of the operation unit 60 is operated to enter the nuisance fax countermeasure setting mode, and the user sets the processing content for the nuisance fax. FIG. 5 is a flowchart of processing content setting input in the nuisance fax countermeasure setting mode.

  In S <b> 10, processing content is input from the user via the operation unit 60. The user input is any one of “erase”, “store”, and “transfer”. Further, in the case of “transfer”, the “designated address” is also input by the ten key 64 or the character key 68.

  In S20, the MPU 10 determines whether or not the processing content input in S10 is “erase” or “accumulation”. If “deletion” or “accumulation”, the MPU 10 stores the process setting table storage area 30b in S30. “Erase” or “accumulation” is stored in the processing content column. If the determination result in S20 is that the processing content input in S10 is not “erase” or “accumulation”, “transfer” and “designated address” are stored in the processing setting table storage area 30b in S40. The information is stored in the processing content column and the designated address column. In this case, the “designated address” is, for example, a mail address or an IP address. For example, the designated address can be transferred to a mail server or a predetermined folder via a network (LAN). Data transfer via the network can be performed using various protocols. Examples of protocols include electronic mail protocols and file transfer protocols (FTP).

After the input is performed in this manner, the mode setting key 61 of the operation unit 60 is operated to cancel the mode setting.
(Fax reception)
Next, fax reception will be described. Fax reception is well known and will be described briefly. That is, when the NCU 110 connected to the telephone line L1 receives an analog signal from the destination, the analog signal is converted into a digital signal by the modem 100, and the encoded digital signal (received image data) is converted into a codec. 90 is restored. The restored received image data is temporarily stored in the image memory 80.

  Then, the MPU 10 executes the flowchart of FIG. 6 while receiving a fax. This flowchart is a flowchart of the nuisance fax countermeasure program executed in the fax reception stored in the ROM 20.

  When the facsimile apparatus 1 receives a fax, the MPU 10 calculates the black ratio B of the first page of the received image data in S100. Here, the black rate B is the ratio of the printed area to the total area of the paper when the received image data is printed on the paper. If the printed area is large, the black rate increases. If the printed area is small, the black rate decreases. When calculating the black rate, the paper size to be printed and the resolution of the received image data are required. The size and resolution of the paper are determined by the DSC signal (digital command signal) received from the communication destination together with the received image data. Obtained from. That is, the MPU 10 detects the document size and resolution of the received image data based on the bit number in the DSC signal.

  In S110, the MPU 10 determines whether or not the black rate B is greater than or equal to the set value P. This set value P is a threshold for determining whether or not the received image data is a nuisance fax, and selects a photo or a figure with many figures such as an advertisement such as DM (direct mail). It is a threshold for. This set value P is a value obtained statistically by measuring the black rate of a nuisance fax such as DM. If it is greater than or equal to the set value P, there are many photographs and figures, and there is a possibility that it is a nuisance fax.

  If the black rate B is less than the set value P in S120, the MPU 10 outputs the received image data stored in the image memory 80 to the recording unit 50 for printing in S170, and ends this program. At this time, the MPU 10 records the transmission source, the reception date and time, the number of received sheets, and the processing content in the processing content history storage area 30a of the RAM 30 shown in FIG. The sender is a fax number obtained based on a TSI signal or a cola ID signal at the time of reception. The reception date and time is obtained from a timer (not shown) provided in the MPU 10. The number of received images is the number of received image data counted by the MPU 10 during reception.

  If the black rate B is greater than or equal to the set value P in S120, the MPU 10 sets a print prohibition flag for the currently received image data, and proceeds to S130. This print prohibition flag is a flag for preventing the stored received image data or the transferred received image data from being printed when the processing content of the received image data is stored or transferred.

  In S130, the MPU 10 determines whether or not the processing content of the processing setting table in the RAM 30 is an erasure setting. If the MPU 10 determines that the deletion setting is set in S130, the MPU 10 deletes the received image data once stored in the image memory 80 in S180. In this case, the MPU 10 does not record the transmission source, the reception date and time, the number of receptions, and the processing content in the processing content history storage area 30a of the RAM 30 shown in FIG.

  Next, the process proceeds to S <b> 160, and the message content corresponding to the processing content “erasure” of the message table 200 is presented on the display unit 70. That is, the MPU 10 displays (presents) “the received fax has been erased without printing because the received fax may be a nuisance fax”, and ends this program.

  In this embodiment, when the processing content is erasure, the sender, the reception date and time, the number of receptions, and the processing content are not recorded in the processing content history storage area 30a. Also good.

If the erasure setting is not set in S130, the MPU 10 determines in S140 whether the processing content of the processing setting table in the RAM 30 is the transfer setting.
If the MPU 10 determines in S140 that the transfer setting is set, the process proceeds to S190. In S190, the MPU 10 transfers the received image data temporarily stored in the image memory 80 to the PC at the specified destination address stored in the processing setting table. At this time, the MPU 10 records the transmission source, the reception date and time, the number of receptions, and the processing content in the processing content history storage area 30a of the RAM 30 shown in FIG.

  Next, the process proceeds to S <b> 160, and the message content corresponding to the processing content “transfer” in the message table 200 is presented on the display unit 70. That is, the MPU 10 causes the display unit 70 to display (present) “Received FAX may be a nuisance FAX, so the received data has been transferred to the designated destination without printing”, and ends this program. To do.

  If the transfer setting is not set in S140 and the storage is set, the MPU 10 stores the received image data in the image memory 80 as it is in S150. At this time, the MPU 10 records the transmission source, the reception date and time, the number of received sheets, and the processing content in the processing content history storage area 30a of the RAM 30 shown in FIG.

  In step S <b> 160, the MPU 10 presents the message content corresponding to the processing content “accumulation” in the message table 200 on the display unit 70. That is, the MPU 10 displays (presents) “the received fax has been stored without printing because the received fax may be a nuisance fax”, and ends this program.

  In the PC (not shown) to which the received image data is transferred, after the user confirms the reception on the display (not shown) of the PC, if necessary, the print prohibition flag attached to the received image data is set to the keyboard of the PC. Reset by inputting. Then, the user transfers the data again from the PC to the facsimile apparatus 1 or transfers and prints it with a printer device connected to another LAN.

  Further, when the received image data is stored in the image memory 80, if the user needs it, the mode setting key 61 of the operation unit 60 is used to shift to the print prohibition flag release mode, and reception is performed under this mode. The print prohibition flag attached to the image data is reset by inputting a release key (not shown) of the operation unit 60. Then, the user shifts to the print mode with the mode setting key 61 of the operation unit 60 and prints the received image data with the recording unit 50 under this mode.

  If the user needs, the mode setting key 61 of the operation unit 60 is used to shift to the processing content history history printing mode, and the contents recorded in the processing content history storage area 30a are recorded under this mode. Printing is performed by the unit 50.

Now, according to this embodiment, there are the following features.
(1) In the facsimile apparatus 1 of the present embodiment, the MPU 10 determines the possibility of a nuisance fax based on received image data received by facsimile as a determination unit. That is, the MPU 10 determines that the possibility of annoying fax is high when the black rate B is equal to or greater than the set value P. And based on this determination result, MPU10 determined the processing content of the said received image data as a 1st determination means. As a result, it is possible to classify the nuisance faxes and the non-nuisance faxes, and it is possible to suppress costs that increase due to the nuisance faxes and unnecessary work due to the nuisance faxes.

  (2) In the facsimile apparatus 1 of the present embodiment, the MPU 10 calculates the black rate of received image data received by facsimile as a calculation means. Then, based on the calculation result of the black rate, the MPU 10 determines the processing content of the received image data as the first determination unit. As a result, it is possible to classify the nuisance fax and the non-nuisance fax according to the calculated black rate of the received image data, and there is an effect that the cost increased due to the nuisance fax and unnecessary work can be suppressed by the nuisance fax.

  (3) In the facsimile apparatus 1 of the present embodiment, the MPU 10 determines the processing contents of the entire received job, that is, the entire processing of the received image data, based on the black rate of the first page (part) of the received image data. The contents were decided. As a result, it is possible to classify the nuisance fax and the non-nuisance fax according to the calculated black rate of the received image data, and there is an effect that the cost increased due to the nuisance fax and unnecessary work can be suppressed by the nuisance fax.

  (4) In the facsimile apparatus 1 of the present embodiment, the RAM 30 (processing setting table storage area 30b) sets the processing contents when it is determined that no printing (normal printing is not performed) as the first setting means. When the MPU 10 determines that there is no printing based on the black rate calculation result, the MPU 10 determines the processing content based on the setting content (setting content). As a result, when the MPU 10 determines that there is no printing, it is possible to perform processing according to preset processing contents.

  (5) In the facsimile apparatus 1 of the present embodiment, the RAM 30 is configured to record the determined processing content (erasure, transfer, or accumulation) as processing history information as a recording unit. As a result, the processing history information (erasure, transfer, or accumulation) recorded in the RAM 30 is read later and printed, so that the user can know the processing history.

  (6) In the facsimile apparatus 1 of the present embodiment, the processing history information (erasure, transfer, or accumulation) is stored in the processing content history storage area 30a of the RAM 30 using the RAM 30 (processing setting table storage area 30b) as recording setting means. Set whether to record or not. The RAM 30 records the processing content (erase, transfer, or accumulation) according to the setting of the recording setting means. As a result, the user can know the history of the process by reading the history of the process recorded in the RAM 30 later.

  (7) In the facsimile apparatus 1 of the present embodiment, the processing history information recorded in the processing content history storage area 30a is presented (printed) using the recording unit 50 as the presenting means. As a result, the processing history information recorded in the processing content history storage area 30a can be presented, so that the user can check the processing history information.

(Second Embodiment)
Next, a second embodiment will be described with reference to FIGS.
In addition, in order to avoid duplication description, it demonstrates centering on a different location about the same or equivalent structure effect | action as 1st Embodiment. In the present embodiment, the configuration of the processing setting table storage area 30b is different from the flowchart of the nuisance fax countermeasure program.

  As shown in FIG. 8, the processing setting table in the processing setting table storage area 30b can arbitrarily set “accumulation”, “transfer”, and “erase” as processing contents according to the size of the black rate B. Each processing content has a recording flag writing area. In addition, the designated destination address can be written in the column in which “transfer” is set.

(Annoying fax countermeasure setting mode)
First, the user operates the mode setting key 61 of the operation unit 60 to enter the nuisance fax countermeasure setting mode, and sets whether or not to record the processing history for the nuisance fax. Specifically, any one of “accumulation”, “transfer”, and “erase” processing may be set according to the size of the black rate B. Alternatively, in this embodiment, the black rate B is Among the three sizes, the processing of the two black rate sizes may be set to the same processing. In addition, when recording the history of processing, when operating the operation unit 60 for each processing content of the processing setting table to set a recording flag in the recording presence / absence column and when recording is not performed, Do not set.

  When the “transfer” process is set, the PC address on the LAN L2 is input to the “specified destination address” of the process setting table by the ten key 64 or the character key 68. After the input is performed in this way, the mode setting key 61 of the operation unit 60 is operated to cancel the mode setting.

(Fax reception)
The MPU 10 executes the flowchart of FIG. 9 when receiving a fax. This flowchart is a flowchart of a nuisance fax countermeasure program executed in the fax reception stored in the ROM 20, and in the present embodiment, the black rate B is divided into three sizes and divided. 10 is a flowchart of an example in which different processes are set according to the size of the black rate B.

In addition, about the step same as the flowchart of 1st Embodiment, the same step number is attached | subjected and the description is abbreviate | omitted.
In S112, S114, and S116, the magnitude relationship between the black rate B of the first page of the received image data and the set values P1, P2, and P3 is determined. Note that P1 <P2 <P3. Here, when the black rate B is equal to or greater than the set value P3, it is determined that the possibility of the nuisance fax is highest, and when the black rate B is equal to or greater than P2 and less than P3, the possibility of the nuisance fax is greater than P3. If the black rate B is not less than P1 and less than P2, it is further determined that the possibility of annoying fax is lower than in the case of not less than P2 and less than P3. The magnitudes of these set values P1 to P3 are set in advance based on empirical rules derived from statistics or the like.

  In this flowchart, when the MPU 10 determines in S112 that the black rate B is less than the set value, normal printing is performed in S170. If the MPU 10 determines “YES” in S112 and P2> B ≧ P1 in S114, the received image data is stored in S150. If the MPU 10 determines “YES” in S114 and P3> B ≧ P2 in S116, the received image data is transferred in S190. If the MPU 10 determines “YES” in S 116, the received image data is erased in S 160.

  FIG. 7 is an example of the processing content history recorded in the processing content history storage area 30a in S150, S170, S180, and S190 in the flowchart of FIG. 9. Unlike the first embodiment, the processing content includes In addition to printing and transfer, processing contents for erasure and storage are also recorded.

In the second embodiment, the second embodiment has the following characteristics in addition to the same effects as (1) to (3) and (5) to (7) of the first embodiment.
(1) In the facsimile apparatus 1 according to the second embodiment, the processing setting table storage area 30b is set as the second setting means in such a manner that the processing content is set in association with the black rate level. Then, when determining the processing content based on the calculation result of the black rate B, the MPU 10 refers to the setting content of the processing setting table storage area 30b and determines the processing content based on the black rate level as the first determination unit. I tried to do it.

As a result, the MPU 10 can perform processing according to the processing content set in association with the black rate level.
(Third embodiment)
Next, a third embodiment will be described with reference to the flowchart of FIG.

The hardware configuration of the third embodiment is the same as that of the first embodiment, and a part of the flowchart described in FIG. 6 is different.
In the present embodiment, the process of S100A is performed instead of S100 of the first embodiment, and S120 of the first embodiment is omitted, and after the process of S100A is performed, the process of S110 is performed.

  Specifically, in S100A, unlike the first embodiment, the black rate B is calculated for each page of all received image data, and finally the arithmetic average value is calculated. This value is the black rate B of the entire received job received this time. The calculation of the black ratio of each page may be performed while receiving and storing it in the image memory 80 for each page. Alternatively, after receiving all the pages once and storing them in the image memory 80, the pages may be calculated. The black rate may be calculated by sequentially reading out each time.

The third embodiment has the following features.
(1) In the facsimile apparatus 1 according to the third embodiment, the MPU 10 determines the processing contents of the entire received job based on the black rate of all pages of the received image data as the first determining unit. As a result, since the processing content of the entire received job is determined based on the received image data of all pages, it is appropriate compared with the case where the processing content of the entire received job is determined based on some received image data. Judgment (determination of processing contents) can be made.

(Fourth embodiment)
Next, a fourth embodiment will be described with reference to FIGS. In the fourth embodiment, the hardware configuration is the same as that of the first embodiment. In the fourth embodiment, the recording unit 50 includes a paper feed cassette A in which a back paper that uses the back of paper on which one side has already been printed, and a paper feed cassette B in which a renewal paper is set. It shall be provided with. In the present embodiment, a cassette attribute table 30c shown in FIG. The cassette attribute table 30c can select two types of paper feed cassettes according to the magnitude relationship between the black rate B and the set value P. That is, when the black rate B ≧ the set value P, the paper feed cassette A on which the back paper is set is selected, and when the black rate B <the set value P, the paper feed with the additional paper set is set. Cassette B is selected.

  The flowchart of FIG. 11 is a flowchart of the nuisance fax countermeasure program executed in the fax reception stored in the ROM 20. In addition, the same step as 1st Embodiment attaches | subjects the same step number, and abbreviate | omits the description.

  If the MPU 10 determines “YES” in S110 after the process of S100, the MPU 10 selects the paper feed cassette A (back paper cassette) with reference to the cassette attribute table 30c in S200, and the recording unit 50 in S210. The received image data is printed.

  If the MPU 10 determines “NO” in S110, it refers to the cassette attribute table 30c in S220, selects the paper feed cassette A (back paper cassette), and receives it at the recording unit 50 as normal printing. Print image data.

The fourth embodiment has the following features.
(1) In the facsimile apparatus 1 according to the fourth embodiment, the MPU 10 determines the possibility of annoying fax based on the received image data received by facsimile as a determination unit. Specifically, the possibility of a nuisance fax was determined based on the black rate of the first page of the received image data. Then, the MPU 10 determines a sheet to be used for printing the received image data based on the determination result as the second determination unit. As a result, it is possible to classify the nuisance fax and the non-nuisance fax, and there is an effect that the cost that increases due to the nuisance fax and unnecessary work can be suppressed by the nuisance fax.

  (2) In the facsimile apparatus 1 according to the fourth embodiment, the MPU 10 calculates the black rate of received image data received by facsimile as a calculation means. Further, the MPU 10 determines a sheet to be used for printing the received image data based on the calculation result of the black rate as a third determining unit. As a result, it is possible to classify the nuisance fax and the non-nuisance fax according to the calculated black rate of the received image data, and there is an effect that the cost increased due to the nuisance fax and unnecessary work can be suppressed by the nuisance fax.

  (3) In the facsimile apparatus 1 of the fourth embodiment, the MPU 10 determines the paper type of the paper used for printing based on the black rate. As a result, since the paper type of the paper to be used for printing is determined based on the calculated black rate of the received image data, it is possible to use inexpensive paper against the troublesome fax, and the cost is reduced by the troublesome fax. Can be achieved.

In addition, you may change embodiment of this invention as follows.
In the above-described embodiment, the present invention is embodied in a facsimile apparatus capable of network scanning, but may be embodied in a communication terminal apparatus that is a multifunction machine having a facsimile and copy function.

  In the above embodiment, the presentation unit is the recording unit 50. However, instead of the recording unit 50 or together with the recording unit 50, a voice generation device is provided as a presentation unit, and the voice generation device is configured according to the processing content. Message content may be generated (presented). The display unit 70 may be used as a presentation unit.

  In the first embodiment, the black ratio of the first page of the received image data is calculated. However, although not the second page, the third page, or the whole page, the average value of the black ratios of a plurality of pages is calculated. It is also possible to calculate and determine the processing content based on the result.

  In the first embodiment, the processing content set in the processing setting table of the processing setting table storage area 30b is recorded in the processing content history storage area 30a. In addition, a storage area for a recording flag may be further provided in the processing setting table storage area 30b in order to set whether or not to record. In this way, if the recording flag is set (set) when the set processing is performed, the set processing is recorded in the processing content of the processing content history storage area 30a, and the recording flag is set. If it is not set, it is possible to prevent the recording of the processing set in the processing content of the processing content history storage area 30a from remaining.

  In the first embodiment, the configured history information consisting only of the transferred reception job is read from the processing content history storage area 30a and printed on the recording unit 50 or displayed on the display unit 70. Anyway.

  In the first embodiment, for each processing content, a history table is stored in the RAM 30, or a corresponding job is extracted from the common processing content history storage area 30a based on the processing content, and a recording unit It may be printed at 50 or displayed on the display unit 70.

In the second embodiment, the set value is three, but the set value may be four or more or two so as to have a magnitude relationship.
In the second embodiment, when there is a possibility of annoying fax (when the black rate B is P1 or more), the processing is accumulation, transfer, and erasure. You may make it set. In this case, since the toner density is printed low, the toner consumption rate can be suppressed even in the case of a nuisance fax, compared to the case where printing is performed with a high density.

  In the third embodiment, the black rate of each page of the received image data is calculated, and the arithmetic average is set as the black rate of the entire received job. Instead, the MPU 10 determines whether or not the black rate for each page exceeds the set value P, and the number of pages exceeding the set value P is determined based on the ratio of the total number of pages in the entire received job. It may be determined. In this case, “the ratio of the number of pages whose black rate exceeds the set value P to the total number of pages is the black rate of the entire received job”.

  In this case, instead of the setting value P in S110 of the third embodiment, the threshold value is compared with the setting value P5. This set value P5 is set in advance based on an empirical rule derived by taking statistics or the like in the case of annoying fax.

  For example, in the step instead of S110, when the MPU 10 determines that 1/2 (= P5) of all pages exceeds the set value P, it is determined that there is a possibility of annoying fax, and the process proceeds to S130. To do.

  Also, if the number of pages exceeding the set value P is not the ratio of the total number of pages in the entire received job, but the number of pages whose black rate exceeds the set value P exceeds the predetermined number of pages, annoying fax is possible. Since there is a possibility, you may make it transfer to S130. The predetermined number of pages is set in advance by an empirical rule derived by taking statistics or the like in the case of annoying fax.

  In the third embodiment, as in the second embodiment, a plurality of determination setting values are prepared, and the processing content is determined according to the black rate level of the entire received job. good.

  In the fourth embodiment, the paper types of backing paper and renewal paper are used. However, high-quality and low-quality paper types may be used. For those with a high possibility of nuisance faxing, if low-quality paper with no cost is set in the paper feed cassette instead of the back paper, the printing cost can be suppressed as in the fourth embodiment.

  In the fourth embodiment, the cassette attribute table 30c is provided. However, in a facsimile apparatus that cannot store attributes, if the black rate is high and the possibility of annoying fax is high, the cassette number used when the black rate is high. May be set in advance, and the backing paper may be accommodated in the cassette. Further, instead of the backing paper, low quality paper may be set.

  In the fourth embodiment, the paper feed cassette for the back paper and the paper feed cassette for the additional paper are used. However, when the black rate is larger than the set value P, printing is performed regardless of the size of the received image data. The paper size to be used may be fixed (for example, A4 size). That is, when the size larger than A is the received image data, the MPU 10 can suppress unnecessary toner consumption by reducing the print size to A4. When the received image data is printed after being reduced, the original received image data is preferably stored in the image memory 80 as it is. If the received image data stored in the image memory 80 is reduced and printed, it may be difficult to see because the print is small. In this case, the received image data is reduced by the original data stored in the image memory 80. Do not print.

  In the facsimile apparatus 1 according to the fourth embodiment, the MPU 10 may determine the paper size of the paper used for printing based on the black rate. In this case, in the cassette attribute table 30c, in the attribute column, a small size paper is used instead of the back paper, and a large size paper is used instead of the renewal paper. Then, when the black rate B is larger than the set value P, the MPU 10 also selects the paper feed cassette A in which small size paper is set in S200 of FIG. In this way, since the paper size of the paper to be used for printing is determined based on the calculated black rate of the received image data, a paper having a small paper size with respect to the annoying fax, that is, a paper with a low cost is used. It can be used, and the cost can be reduced by annoying fax.
