The connection housing 8 incorporates a paper conveyance path for conveying the recording paper after fixing in the image forming process and discharging it to the sheet tray 6.

  In the multifunction device 1, the original image read by the image reading unit 2 is formed on a recording sheet fed from one of the sheet feeding cassettes 7 by the image forming mechanism built in the lower housing 3, The recording paper after image formation is discharged from the paper conveyance path in the connection housing 8 to the sheet tray 6.

  Next, the configuration of the multifunction machine 1 as the facsimile apparatus according to the embodiment of the present invention will be described. FIG. 2 is a block diagram showing an outline of the internal configuration of the multifunction machine 1 as the facsimile apparatus according to the embodiment of the present invention.

  The MFP 1 according to the embodiment of the present invention includes a control unit 100, an image reading unit 2, a memory 120, an image forming unit 130, and a facsimile communication unit 140.

  The image reading unit 2 includes a scanner that reads a document and obtains a document image. The image reading unit 2 is, for example, an ADF (Auto Document Feeder) having a document placing table, a scanner that reads an image of a document conveyed from the document placing table, and a discharge mechanism that discharges a read document. The image reading unit 2 reads a document to be faxed one by one and generates data to be faxed.

  The memory 120 is a target for image formation (printing) of the image forming unit 130 such as document data read by the image reading unit 2, data to be transmitted by the facsimile communication unit 140 or the communication interface 160. This is an area for temporarily storing data. A partial area of the memory 120 is used as an address book 1201 as a transmission destination storage unit for storing a transmission destination of facsimile data transmission by the facsimile communication unit 140.

  The image forming unit 130 reads data stored in the memory 120, such as data of a document read by the image reading unit 2, data acquired by the facsimile communication unit 140 or the communication interface 160, and the like. Is used for image formation (printing).

  A facsimile communication unit (facsimile data receiving unit) 140 executes various functions necessary for facsimile communication and transmits / receives image data to / from an external facsimile apparatus through a public line.

  The control unit 100 includes a CPU, a ROM, a RAM, and the like, and governs the overall operation of the multifunction device 1. The control unit 100 includes a control unit 101, a reception permission / rejection determination unit 102, a determination setting unit 103, a resolution detection unit 104, a preview image creation unit 105, and an operation instruction reception unit 106.

  Note that a fax communication program of the MFP 1 is stored in the HDD 170 or a ROM (not shown), and the control unit 100 operates in accordance with the fax communication program, whereby the control unit 101, the reception permission / rejection determination unit 102, It functions as a determination setting unit 103, a resolution detection unit 104, a preview image creation unit 105, and an operation instruction reception unit 106, and includes these units.

  However, the control unit 101 (control unit 101 for functions related to fax job management), the reception permission determination unit 102, the determination setting unit 103, the resolution detection unit 104, the preview image creation unit 105, and the operation instruction reception unit 106 Each may be configured by a hardware circuit regardless of the operation based on the fax communication program. The same applies to each embodiment unless otherwise specified.

  In addition, each unit of the control unit 101 to the operation instruction receiving unit 106 is a component of the multi-function device 1 as an embodiment of the present invention as long as it is necessary for each process shown in an embodiment described later.

  The control unit 101 governs the overall operation of the multifunction machine 1.

  For example, the control unit 101 reads document data of each page read by the image reading unit 2 for fax transmission and temporarily stored in the memory 120 in page order, and causes the facsimile communication unit 140 to perform an operation by the user. Fax transmission is performed to the destination facsimile machine designated by the operation of the unit 47.

  Further, the control unit 101 reads out the facsimile data received by the facsimile communication unit 140 and temporarily stored in the memory 120 in the page order, and causes the image forming unit 130 to form (print) an image.

  The reception permission / refusal determination unit 102 determines whether or not to permit continuous reception of facsimile data in which an incoming call is detected by the facsimile communication unit 140.

  The determination setting unit 103 sets whether or not to make the determination by the reception permission determination unit 102 according to an instruction from the user. For example, when the user operates the operation unit 47 to input an instruction as to whether or not to continue reception of facsimile data whose incoming call has been detected by the facsimile communication unit 140, the reception continuation permission instruction or reception continuation disabling is not performed. In accordance with one of the permission instructions, the determination setting unit 103 sets whether or not the reception permission determination unit 102 makes the above determination.

  That is, the reception permission / rejection determination unit 102 performs the above determination when the facsimile communication unit 140 is set to perform the above determination by the determination setting unit 103 when facsimile data is received from another facsimile apparatus. If the setting unit 103 is not set to perform the determination, the determination is not performed.

  The control unit 101 causes the facsimile communication unit 140 to stop the reception when the reception permission / rejection determination unit 102 determines that the reception of facsimile data whose incoming call has been detected by the facsimile communication unit 140 is not permitted. In addition, the control unit 101 causes the facsimile communication unit 140 to continue the reception when the reception permission determination unit 102 determines that the reception continuation is permitted and when the determination is not performed.

  The resolution detection unit 104 analyzes the image indicated by the facsimile data received by the facsimile communication unit 140 and detects the resolution of the image. The reception permission / rejection determination unit 102 is a case where the transmission destination of the received facsimile data is not stored in the address book 1201, and the resolution of the facsimile data detected by the resolution detection unit 104 is determined in advance. If the value is higher than the predetermined value (for example, super fine 400 (dpi) × 200 (dpi)), it is determined that reception of the facsimile data is not permitted, and the resolution is lower than the predetermined value. It is determined that the reception continuation is permitted.

  The preview image creation unit 105 creates a preview image using a part of facsimile data from a transmission destination that is not stored in the address book 1201 received by the facsimile communication unit 140. This preview image is displayed on the display unit 150 under the control of the control unit 101. When the control unit 101 displays the preview image created by the preview image creation unit 105 on the display unit 150, an permission instruction for permitting continuous reception of facsimile data that is the basis of the preview image is displayed on the operation instruction receiving unit 106. The reception permission determination unit 102 determines that the reception of the facsimile data continues to be permitted. If the permission instruction is not received by the operation instruction reception unit 106, the reception permission determination unit 102 receives the facsimile data. It is determined that continuation is not permitted.

  The display unit 150 includes an LCD (Liquid Crystal Display) or the like that displays operation guidance for the user. The display unit 150 may include a touch panel function to accept various operation instructions from the user as the operation unit 47.

  Further, the multifunction device 1 communicates various data between the image processing unit 190 that performs editing and processing of the image read by the image reading unit 2 and another personal computer or server connected to the network. Communication interface 160.

  Next, fax communication processing between the multifunction machine 1 and a facsimile machine that is a destination of fax transmission will be described. FIG. 3 is a diagram showing a fax communication process between the multifunction device 1 and a facsimile machine that is a destination of fax transmission.

  The multifunction peripheral 1 as the transmission side has a facsimile communication instruction 140 (hereinafter simply referred to as the multifunction peripheral 1 in the description of the facsimile communication process), and a facsimile transmission instruction (that is, facsimile transmission) input by the operation of the operation unit 47 by the user. A call is made by dialing based on (job), and a CNG signal is transmitted to notify the facsimile machine of the other party that the multi-function machine 1 is a facsimile machine that performs facsimile communication (# 1).

  When the other party's facsimile apparatus receives the CNG signal as the receiving side when the facsimile communication unit (hereinafter simply referred to as the other party's facsimile apparatus in the description of the fax communication processing) receives the CNG signal, the destination facsimile apparatus As a CED signal and a DIS signal notifying the receiving side device function (CCITT specification, etc.) are sent back to the multi-function device 1 (# 2).

  Upon receiving the CED signal and the DIS signal from the destination facsimile machine, the multifunction device 1 (calling side) sends a DCS signal that informs the setup data (CCITT specifications, etc.) of the multifunction device 1 and a TCF signal for modem training. Send to the destination facsimile machine (# 3).

  The counterpart facsimile apparatus that has received the DCS signal and the TCF signal returns a CFR signal indicating successful reception to the multi-function device 1 (# 4).

  When the MFP 1 as the transmission side receives the CFR signal, it transmits the first page data (PIX) to be faxed in the fax transmission job to the partner facsimile machine (# 5). Further, when there is data on another page to be faxed, the multifunction device 1 transmits an MPS signal indicating that the data on the other page exists to the partner facsimile machine.

  In the other party facsimile machine as the receiving side, the received first page data (PIX) is temporarily stored in the image memory. Then, the counterpart facsimile machine returns an MCF signal indicating that the data of the first page has been correctly received to the multi function device 1 (# 6). The destination facsimile machine as the receiving side transmits an RNR signal indicating the busy state to the multi-function device 1 instead of the MCF signal when the facsimile transmission is stopped in one embodiment. The counterpart facsimile machine as the receiving side transmits the MCF signal to the multi-function device 1 after transmitting the RNR signal, after canceling the busy state, or when receiving the subsequent data.

  When receiving the MCF signal from the partner facsimile machine, the multifunction device 1 transmits the next page data (PIX) and the MPS signal to the partner facsimile machine as long as there is next page data to be faxed. In this case, the destination facsimile apparatus repeats the process of # 6 in which the received page data (PIX) is temporarily stored in the image memory and the MCF signal is returned to the multifunction machine 1. Thereafter, the processes of # 5 and # 6 are repeated until the multi-function device 1 completes transmission of all pages of data to be transmitted to the facsimile machine.

  When the multifunction device 1 transmits the final page data (PIX) to be transmitted to the facsimile machine, the multifunction apparatus 1 transmits an EOP signal indicating the end of data transmission to the facsimile machine ( # 7). The counterpart facsimile machine returns an MCF signal indicating that the data of the last page has been received to the multi function device 1 (# 8).

  When the multifunction device 1 receives the MCF signal from the partner facsimile machine after transmitting the EOP signal, it transmits a DCN signal to the partner facsimile machine and disconnects the line (# 9).

  Next, a facsimile data reception process performed by the multifunction machine 1 as a facsimile apparatus that receives facsimile data will be described. FIG. 4 is a flowchart showing a facsimile data reception process performed by the multifunction machine 1 as a facsimile apparatus on the facsimile data receiving side.

  When the facsimile communication unit 140 of the MFP 1 transmits facsimile data from another facsimile apparatus and an incoming call is detected (YES in S1), the reception permission / rejection determination unit 102 detects the incoming call by the determination setting unit 103. It is determined whether or not the setting is made to determine whether or not to continue the reception of the facsimile data started in this manner (S2).

  Here, the reception permission / rejection determination unit 102 does not perform the determination when determining that the determination setting unit 103 is not set to perform the determination (NO in S2). In this case, the control unit 101 causes the facsimile communication unit 140 to continuously receive the facsimile data transmitted from the transmission side facsimile apparatus as it is (S15).

  On the other hand, if the reception permission / rejection determination unit 102 determines that the determination setting unit 103 has been set to perform the above determination (YES in S2), the above-described determination includes the processes of S3 to S14 illustrated in FIG. Is done.

  In S3, the reception permission / refusal determination unit 102 determines whether or not a fax number indicating a transmission-side facsimile apparatus as a transmission destination that has transmitted the facsimile data is stored in the address book 1201 (S3).

  Here, when the reception permission / refusal determination unit 102 determines that the fax number of the transmission destination is stored in the address book 1201 (YES in S3), unless a communication error has occurred, that is, it does not occur. (NO in S16), the control unit 101 causes the facsimile communication unit 140 to continuously receive facsimile data transmitted from the transmission-side facsimile apparatus (S15).

  If the reception permission / rejection determination unit 102 determines that a communication error has occurred (YES in S16), the reception permission / rejection determination unit 102 permits the reception of facsimile data transmitted from another facsimile apparatus thereafter. Measurement is started by a timer for a predetermined elapsed time t1 used for determining whether or not to perform (S17). The timer is built in the control unit 100, for example. In addition, the reception permission / rejection determination unit 102 resets the previous elapsed time t1 measured by the timer, and then starts the measurement of the new elapsed time t1 in S17 by the timer. After the timer setting, the control unit 101 blocks the fax communication established with the transmission side facsimile apparatus by the facsimile communication unit (S18), and then the process ends.

  On the other hand, if the reception permission / rejection determination unit 102 determines in S3 that the fax number of the transmission destination is not stored in the address book 1201 (NO in S3), the resolution of the image indicated by the received facsimile data Is detected by the resolution detection unit 104 (S4). Then, the reception permission / refusal determination unit 102 determines whether or not the resolution detected for the facsimile data is equal to or greater than a predetermined value (for example, super fine 400 (dpi) × 200 (dpi)) (S5). .

  If the reception permission determination unit 102 determines that the resolution of the facsimile data is smaller than the predetermined value (NO in S5), the reception permission determination unit 102 permits the reception of the facsimile data to be continued. The control unit 101 causes the facsimile communication unit 140 to continuously receive the facsimile data transmitted from the transmission side facsimile apparatus (S15). The facsimile data having a small resolution is received because it does not require a relatively long time to receive. In addition, this makes it possible to prevent reception of facsimile data that is highly likely to be an advertisement with many photographs and images.

  Further, when the reception permission / rejection determination unit 102 determines that the resolution of the facsimile data is equal to or higher than the predetermined value (YES in S5), the reception permission / rejection determination unit 102 subsequently decodes the received facsimile data. It is determined whether or not the data amount for the number of bands (for example, one band) is equal to or greater than a predetermined data amount (for example, 50 KB) (S6).

  Here, when the reception permission determination unit 102 determines that the data amount for the band is smaller than the predetermined data amount (NO in S6), the control unit 101 causes the facsimile communication unit 140 to transmit to the transmission side. The facsimile data transmitted from the facsimile apparatus is continuously received (S15). Thus, when the data amount for a predetermined number of bands is small, it is assumed that the facsimile data does not require a relatively long time for reception.

  On the other hand, when it is determined that the data amount for the band is equal to or greater than the predetermined data amount (YES in S6), the reception permission / refusal determination unit 102 continues to make the following determination (S7). That is, an error has occurred in other previous facsimile data received prior to the reception of the facsimile data when the previous facsimile data is received, and an elapsed time t1 from the time of the occurrence of the error is set in advance. Based on the time measurement by the timer, the reception permission / rejection determination unit 102 determines whether a predetermined elapsed time T1 (for example, 120 seconds) has been reached.

  If the reception permission / refusal determination unit 102 determines that the elapsed time t1 from the occurrence of the error has reached the elapsed time T1 (YES in S7), the control unit 101 causes the facsimile communication unit 140 to transmit to the transmitting facsimile machine. The facsimile data transmitted from the terminal is continuously received (S15). If the elapsed time T1 has elapsed, it is unlikely that the facsimile apparatus that transmitted the previous facsimile data will transmit the facsimile data again by retrying, so that the other newly transmitted facsimile data is received. Let

  In addition, when the reception permission / refusal determination unit 102 determines that the elapsed time t1 from the occurrence of the error has not reached the elapsed time T1 (NO in S7), the preview image creation unit 105 continues to the facsimile communication unit 140. Whether the facsimile data received by the number reaches a predetermined amount of data necessary for use in creating a preview image, for example, a predetermined number of image lines (lines read by the scanner of the image reading unit 2) (S8), and waits until the received facsimile data reaches a predetermined number of image lines (NO in S8).

  When the preview image creation unit 105 determines that the received facsimile data has reached a predetermined number of image lines (YES in S8), the preview image creation unit 105 uses the data for the predetermined number of image lines to generate a preview image. Create (S9). The control unit 101 displays the preview image on the display unit 150 together with a message that prompts the user to input an instruction as to whether or not to continue receiving the facsimile data (S10).

  Subsequently, the reception permission / rejection determination unit 102 causes the timer to further measure a predetermined standby time t2 (for example, 60 seconds) (S11). The measurement of the waiting time t2 by the timer is started when the preview image is displayed on the display unit 150. Note that the reception permission / refusal determination unit 102 resets the previous standby time t2 measured by the timer, and then starts the measurement of the new standby time t2 in S11 by the timer.

  Thereafter, until the reception permission determination unit 102 measures the elapse of the standby time t2 by the timer (NO in S12), the user operates the operation unit 47 to receive the received facsimile data (in the display unit 150). An instruction as to whether or not to continue reception of the facsimile data that is the basis of the displayed preview image) is accepted by the operation instruction accepting unit 106 (YES in S13), and the instruction instructs to continue reception of the facsimile data. If it is determined that the permission instruction is permitted (YES in S14), the control unit 101 causes the facsimile communication unit 140 to continuously receive the facsimile data transmitted from the transmission-side facsimile apparatus (S15).

  Note that if the reception permission determination unit 102 determines that the instruction received by the operation instruction reception unit 106 is a non-permission instruction that does not permit the reception of the facsimile data to be continued (YES in S13, NO in S14), the control unit 101 causes the facsimile communication unit 140 to stop receiving the facsimile data transmitted from the transmission side facsimile apparatus (S19), and cuts off the fax communication line established with the transmission side facsimile apparatus (S19). S20).

  On the other hand, if neither the permission instruction nor the disapproval instruction is received by the operation instruction receiving unit 106 within the waiting time t2 (NO in S13, YES in S12), the control unit 101 causes the facsimile communication unit 140 to Then, the reception of the facsimile data transmitted from the transmission side facsimile apparatus is stopped (S19), and the line of fax communication established with the transmission side facsimile apparatus is blocked (S20).

  Here, the setting by the determination setting unit 103 will be described. FIG. 5 is a diagram illustrating the operation unit 47 and the display unit 150, and FIGS. 6 to 8 are diagrams illustrating examples of the display screen of the display unit 150.

  When the user touches the system menu button B1 in the initial display screen D1 displayed on the display unit 150 shown in FIG. 5, an instruction to change the setting of any function provided in the multifunction device 1 is given by the touch panel function. The control unit 101 causes the display unit 150 to display a system menu screen D2 shown in FIG.

  Subsequently, when the user touches the function button B2 corresponding to the desired function, here, the fax function, an instruction to change the setting of the fax function by the touch panel function is received from the user by the operation unit 47 by the touch panel function, The control unit 101 causes the display unit 150 to display a fax setting change screen D3 illustrated in FIG.

  Subsequently, when the user touches an item whose setting is to be changed in the fax setting change screen D3, here, a “received image check mode” button B3 corresponding to the received image check mode, a reception permission / inhibition determination unit is performed by a touch panel function. An instruction to change various values used by 102 for the determination is received from the user by the operation unit 47 by the touch panel function, and the control unit 101 causes the display unit 150 to display a value change screen D4 shown in FIG.

  When the user touches the image portion indicating the item whose value is to be changed when the value change screen D4 is displayed, for example, the contents and values that are candidates for input by pull-down display, for example, are displayed as a list for the item. When the content or value portion is touched, the content or value being displayed is received by the operation unit 47 by the touch panel function, and the reception permission / rejection determination unit 102 determines the resolution value used for the determination corresponding to the touched portion, The content or value of the elapsed time t1, which is used when a communication error occurs, the predetermined data amount for the data amount for a predetermined number of bands, or the waiting time t2 of the signal indicating whether or not reception from the user is permitted. The value of the received content is received and stored as data used for the determination.

  In the facsimile data reception processing described above, the reception permission / rejection determination unit 102 sets the condition for stopping the reception of facsimile data received by the multifunction device 1 as follows: (1) The fax number of the transmission destination is stored in the address book 1201. It is not stored, (2) the resolution detected for the received facsimile data is greater than or equal to the predetermined value, and (3) a predetermined value obtained by decoding the received facsimile data. Satisfying all that the amount of data for the number of bands is equal to or greater than a predetermined amount of data, and (4) that there is no instruction indicating whether or not to continue receiving facsimile data within the waiting time t2, or (5) If any of the non-permission instructions indicating whether or not to continue receiving the facsimile data is within the waiting time t2, the facsimile data is satisfied. The reception continuation is aborted, squeezed to accurately high probability facsimile data is unnecessary for the user, it is possible to stop receiving continued only for facsimile data is highly probable is unnecessary.

  In addition, since the determinations (1), (2), (3), (4), and (5) above can be performed even in a situation where the facsimile data that has been received has not been received, for example, for one page, the amount of data is small. With respect to reception of facsimile data, for example, facsimile data for only one page, it is possible to stop the reception of the facsimile data at an early stage after the reception starts.

  In addition, since the determinations (1), (2), (3), (4), and (5) above can be made only by processing in the multifunction machine 1 as a receiving facsimile machine, special communication control and data of the sending facsimile machine are possible. There is no need to seek a transmission agreement. For example, in order to determine whether or not the facsimile data is necessary, it is not necessary to obtain an agreement for a special fax transmission method such as including a special image in the facsimile data for the facsimile apparatus on the transmission side.

  For this reason, according to the present embodiment, it is possible to determine whether or not to receive facsimile data without having to print one page of image information or obtaining a special agreement on the fax transmission method.

  In the above description, the reception permission / inhibition determination unit 102 satisfies the conditions (1), (2), and (3) above for satisfying the conditions for stopping the reception of facsimile data received by the multifunction device 1, and (4) Alternatively, although either of the conditions (5) is satisfied, the condition for stopping the reception of the facsimile data whose reception has been started is not limited to this.

  For example, the reception permission / non-permission determination unit 102 satisfies the above condition (1) when the determination setting unit 103 is set to perform the above determination as a condition for stopping reception of facsimile data that has been started to be received. (2) (3) (4) (5) may satisfy only one of them, and further, only one of the above (1) (2) (3) (4) (5) may be satisfied. It may be satisfied. In these cases, each of the control unit 101 to the operation instruction receiving unit 106 in the control unit 100 shown in FIG. 2 performs the determinations (1), (2), (3), (4), and (5). Only the necessary components are necessary components for the facsimile machine 1 to perform the facsimile data reception process.

  Further, the above embodiment can be variously modified. For example, in S12 illustrated in FIG. 4, the reception permission determination unit 102 waits for input of an instruction as to whether or not to allow continued reception from the user, and the operation instruction reception unit 106 receives the instruction. During this period, when the facsimile communication unit 140 receives a predetermined amount of facsimile data (for example, image data for one page) from a transmission destination not stored in the address book 1201, a facsimile data transmission is performed. The facsimile communication unit 140 may transmit a signal for waiting for the transmission (for example, the RNR signal) to the facsimile apparatus of the transmission destination and temporarily stop transmission of the subsequent facsimile data. As a result, it is possible to avoid a situation in which the facsimile data that has not been determined to be necessary by the user is continuously received and stored in the multifunction device 1.

  In this case, the operation instruction accepting unit 106 is further operated even when a predetermined waiting time t2 has elapsed since the facsimile communication unit 140 received facsimile data from the destination facsimile machine and the display unit 150 displayed the preview image. If neither of the permission instruction or the non-permission instruction from the user is accepted, a signal for resuming facsimile data transmission may be transmitted to the facsimile apparatus of the transmission destination. As a result, the preview image creation unit 105 can further create a preview image using the facsimile data received subsequently, and the newly created preview image is displayed on the display unit 473. The permission / rejection determination unit 102 can determine permission / rejection of facsimile data reception based on the reception permission signal or the reception disapproval signal from the user who has visually recognized the newly created preview image.

  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made. The configurations and processes shown in the above embodiments using FIGS. 1 to 8 are only one embodiment of the present invention, and the configurations and processes of the present invention are not limited thereto.
