Description

  The present invention relates to a facsimile apparatus, and more particularly to a technique for preventing erroneous transmission of a facsimile.

Facsimile transmission methods include automatic transmission and manual transmission. Automatic transmission is a method of automatically starting facsimile transmission when a communication line is connected to the other party. Although automatic transmission is a very convenient method, erroneous transmission is likely to occur. In order to prevent this erroneous transmission, there are business establishments that prohibit automatic transmission. For example, there are places where the following operation procedures 1 and 2 are ruled.
1. 1. Make a call with the other party using the handset. After confirming the other party in a call, operate the start of automatic facsimile transmission

  However, even if it is ruled, the above operating procedure is not always followed. Here, in order to determine whether or not the rule is observed, it is necessary to detect whether or not a call is made with the other party during facsimile transmission. A technique for detecting whether or not a call is made with a partner at the time of facsimile transmission is described in, for example, Patent Document 1 below.

JP 2007-104479 A

  In the above-mentioned Patent Document 1, “a signal obtained from the receiver side, such as a CED signal (calling terminal identification signal) other than the call voice, is removed, and a signal that has flowed to the line from its own device is further subtracted from the signal. It is described that it is confirmed whether or not a call is made with the other party by determining whether or not there is a “signal obtained” (see paragraph [0068]). However, this process is not easy, and the configuration for performing the process becomes complicated, which may lead to a significant increase in cost.

  The present invention has been made in view of the above circumstances, and an object thereof is to make it possible to detect whether the operation procedure of operating the start of facsimile transmission after a call with the other party is followed with a simple configuration. To do.

  The sender of the facsimile transmission transmits a CNG signal (1100 Hz tone for 0.5 seconds, followed by silence for 3 seconds) to the receiver, and when the receiver receives the CNG signal, the CED signal is sent as a response signal. Since (continuous tone of 2100 Hz tone) is transmitted to the caller side, if the receiver side is set to the automatic reception state, the caller side receives the CED signal immediately after the communication line is connected. Note that the CED signal may be transmitted from the receiver side to the caller side regardless of the reception of the CNG signal.

  Therefore, if the caller side detects the CED signal immediately after the communication line is connected, it is determined that the receiver side is set to the automatic reception state and no call is made between the operator and the other party. Can do. In this way, it is possible to determine whether or not a call has been made with the other party from the detection state of the CED signal transmitted from the receiver side.

The present invention is an invention made based on the above knowledge, a facsimile apparatus according to one aspect of the present invention, a data acquisition unit for acquiring data that is a candidate for facsimile communication;
A facsimile transmission image storage unit for storing data acquired by the data acquisition unit as a facsimile transmission image;
A partner receiving unit that receives a partner input indicating a partner to which the facsimile transmission image is transmitted from an operator;
A facsimile communication unit that transmits and receives facsimiles via a communication line;
A control unit that causes the facsimile communication unit to perform facsimile communication with respect to the partner received by the partner reception unit;
A CED signal detector for detecting a CED signal transmitted from the other party;
A determination unit that determines whether or not the CED signal is detected by the CED signal detection unit until a predetermined first time elapses after the communication line is connected to the partner;
The control unit causes the facsimile communication unit to transmit the facsimile transmission image to the destination when the determination unit determines that the CED signal is not detected before the first time elapses. When the determination unit determines that the CED signal has been detected before the first time elapses, the facsimile communication unit does not transmit the facsimile transmission image to the destination. Is.

  According to the present invention, after the line is connected by facsimile communication to the other party, the facsimile transmission image is transmitted to the other party when the CED signal is not detected until the predetermined first time elapses. Since the CED signal is not detected, it is possible to detect that the operation procedure for operating the start of facsimile transmission is not followed after a call with the other party. Then, it is possible to control whether or not to send a facsimile transmission image to the other party according to the state of compliance with the operation procedure, and reliably prevent erroneous facsimile transmission.

  Further, by determining whether or not a call is made with the other party based on the detection state of the CED signal, a system required for detecting whether or not the operation procedure is observed is realized with a relatively simple configuration. be able to.

It is a flowchart which shows an example of the processing operation performed by the control unit in a facsimile apparatus.

  Hereinafter, a facsimile apparatus according to an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a schematic diagram of a system including a facsimile apparatus according to the first embodiment of the present invention. The system 11 includes a multifunction device 1 and a plurality of information terminal devices 21 installed in an office or the like, and a facsimile device 22 installed in another office or the like.

  The multifunction device 1 is a multifunction device having a plurality of functions such as a copy function, a printer function, a scanner function, and a facsimile function. The multi-function device 1 can communicate with another facsimile device 22 via a public telephone line network and can communicate with the information terminal device 21 via a LAN or the like. The multifunction machine 1 is an example of a facsimile machine according to the present invention in the scope of claims.

  The information terminal device 21 is a personal computer, for example, and can communicate with the multifunction device 1 via a LAN or the like. The information terminal device 21 is installed with a printer driver corresponding to the multifunction device 1, can instruct the multifunction device 1 to print an image, and functions as a print control device for the multifunction device 1.

  Next, facsimile communication processing between the multifunction machine 1 and another facsimile apparatus 22 that is a facsimile transmission destination will be described. FIG. 2 is a diagram showing a facsimile communication process between the multifunction machine 1 and the facsimile apparatus 22 which is a facsimile transmission destination.

  The MFP 1 as the transmission side is input by the operation of the operation unit 47 by the operator by the facsimile communication unit 71 (hereinafter simply referred to as the MFP 1 in the description of the facsimile communication process with reference to FIG. 2). A call is made by dialing based on a facsimile transmission instruction (that is, a facsimile transmission job), and a CNG signal is transmitted to notify the other party's facsimile apparatus that the multifunction device 1 is a facsimile apparatus that performs facsimile communication. (# 1).

  When the other party's facsimile apparatus 22 receives the CNG signal as a receiving side when the facsimile communication unit (hereinafter simply referred to as the other party's facsimile apparatus in the description of the facsimile communication processing) receives the CNG signal, A CED signal as a response signal, an NSF signal as a non-standard function identification signal representing an optional function of the device itself, and a DIS signal for notifying a device function (CCITT specification, etc.) on the receiving side are sent back to the multifunction device 1 (# 2 ). For example, the NSF signal is a T.264 signal used in the facsimile apparatus 22 to notify a special facility that is not a specific standard system. This is a message signal according to the 30 protocol.

  Upon receiving the CED signal, the NSF signal, and the DIS signal from the destination facsimile machine 22, the multifunction device 1 (calling side) responds to the DCS signal that informs the setup data (CCITT specifications, etc.) of the multifunction device 1 and the NSF signal. An NSS signal as a non-standard function identification signal and a TCF signal for modem training are sent to the counterpart facsimile machine 22 (# 3). That is, since the special facility is notified by the NSF signal from the facsimile apparatus 22 of the other party, if the caller has a function corresponding to the special facility, the calling side indicates that it can respond. The facsimile apparatus (here, the multifunction machine 1) notifies the facsimile apparatus 22 of the other party by an NSS signal.

  The counterpart facsimile apparatus 22 that has received the DCS signal, NSS signal, and TCF signal returns a CFR signal indicating successful reception to the multi-function device 1 (# 4).

  When the multifunction peripheral 1 as the transmission side receives the CFR signal, the first page data (PIX) to be transmitted by the facsimile transmission job is transmitted to the destination facsimile machine 22 (# 5). . Further, when there is data on another page to be facsimile-transmitted, the multi-function device 1 transmits an MPS signal indicating that data on the other page exists to the counterpart facsimile machine 22.

  The destination facsimile machine 22 as the receiving side temporarily stores the received first page data (PIX) in the image memory. Then, the counterpart facsimile machine 22 returns an MCF signal indicating that the first page of data has been correctly received to the multi-function device 1 (# 6).

  When receiving the MCF signal from the partner facsimile machine 22, the multi-function device 1 transmits the next page data (PIX) and the MPS signal to the partner facsimile machine 22 as long as there is next page data to be transmitted by facsimile. In this case, the destination facsimile machine 22 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 device 1. Thereafter, the processes of # 5 and # 6 are repeated until the multi-function device 1 completes the transmission of the data of all pages to be transmitted to the destination facsimile apparatus 22.

  When the multi-function device 1 transmits the last page data (PIX) to be transmitted to the destination facsimile device 22, the multifunction device 1 transmits an EOP signal indicating the end of data transmission to the destination facsimile device 22. (# 7). The counterpart facsimile machine 22 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 counterpart facsimile machine 22 after sending the EOP signal, it transmits a DCN signal to the counterpart facsimile machine 22 to disconnect the line (# 9).

  FIG. 3 is a functional block diagram showing the main internal configuration of the multifunction machine 1 according to the embodiment of the present invention. The multifunction machine 1 includes a control unit 10, a document feeding unit 6, a document reading unit 5, an image forming unit 12, an image memory 32, an HDD (Hard Disk Drive) 92, a fixing unit 13, a wireless communication unit 73, an operation unit 47, A facsimile communication unit 71, a handset 72, a network interface unit 91, and a speaker 74 are provided.

  The document feeding unit 6 feeds a document to be read to the document reading unit 5.

  The document reading unit (an example of a data acquisition unit) 5 includes a reading mechanism having a light irradiation unit, a CCD (Charge Coupled Device) sensor, and the like under the control of the control unit 10. The document reading unit 5 reads an image from the document by irradiating the document with the light irradiating unit and receiving the reflected light with a CCD sensor.

  The image forming unit 12 forms a toner image of an image to be printed on a sheet.

  The image memory 32 (an example of a facsimile transmission image storage unit) temporarily stores original image data obtained by reading by the original reading unit 5 as a facsimile transmission image, or data to be printed by the image forming unit 12. Is an area for temporarily storing.

  The HDD 92 is a large-capacity storage device that stores document images and the like read by the document reading unit 5.

  The fixing unit 13 fixes the toner image on the paper to the paper by thermocompression bonding.

  The wireless communication unit 73 performs wireless communication with the IC card 4 using a near field communication method such as NFC (Near Field Communication), Bluetooth (registered trademark), or wireless LAN. Here, a case where communication is performed with the IC card 4 using NFC communication will be described.

  For example, from the operator, for example, an operation destination of the facsimile communication, an instruction for executing the facsimile communication, an instruction for executing the image forming operation, or an instruction for executing the document reading operation, for example, from the operator. Etc. are received. The operation unit 47 includes a display unit 473 that displays operation guidance to the operator. The display unit 473 is a touch panel, and the operator can operate the multifunction device 1 by touching buttons and keys displayed on the screen.

  The facsimile communication unit 71 includes an unillustrated encoding / decoding, modulation / demodulation unit, and NCU (Network Control Unit), and performs facsimile transmission / reception using a public telephone line network. When the handset 72 is connected to the facsimile communication unit 71 and a telephone number is input via the operation unit 47 in a state where the handset 72 is off-hooked, a call is made to the other party so that a call can be made with the other party. Become.

  A network interface unit (an example of a data acquisition unit and a communication unit) 91 is configured by a communication module such as a LAN board, and is connected to the network interface unit 91 via a LAN or the like, and is an external device in a local area or on the Internet 20 (for example, the information terminal device 21 shown in FIG. 1) and various data such as a facsimile transmission image are transmitted and received.

  A speaker (an example of a notification unit) 74 outputs a message and a warning sound.

  The control unit 10 operates in accordance with a control program installed in the HDD 92 to control the control unit 100, the user information acquisition unit 101, the available user confirmation unit 102, the setting reception unit 103, the determination unit 105, and the CED signal detection unit. 106, function as a user information storage unit 111, a use history information storage unit 112, an administrator information storage unit 113, and a detailed setting information storage unit 114. However, the control unit 100 and the like can also be configured by hardware circuits independently of the operation according to the control program by the control unit 10.

  The user information storage unit 111 stores a user ID code.

  The usage history information storage unit 112 stores usage history information of facsimile transmission, and is composed of a nonvolatile memory. FIG. 4A is a diagram showing an example of the data configuration of the usage history information storage unit 112. The usage history information storage unit 112 stores the usage date, user ID code, transmission mode (automatic transmission / Manual transmission) and whether or not the operating procedure is violated. The usage history information storage unit 112 is an example of an information storage unit in the claims.

  The administrator information storage unit 113 stores personal information (for example, ID code, name, department name, and mail address information of the information terminal device 21 used by the administrator) of the administrator who manages the multifunction device 1.

  The detailed setting information storage unit 114 stores information indicating “detailed setting” in facsimile transmission. FIG. 4B is a diagram illustrating an example of a data configuration of the detailed setting information storage unit 114. The detailed setting information storage unit 114 includes a standby time T1 for detecting a CED signal (the initial value is, for example, 5 seconds) or information indicating whether or not to prohibit facsimile transmission ("0" indicates transmission prohibition if the "operation procedure" for operating the start of facsimile transmission is not followed after a call with the other party) And “1” indicates transmission permission). The waiting time T1 is an example of the first time in the claims.

  The control unit 100 is responsible for overall operation control of the multifunction machine 1. The document feeding unit 6, the document reading unit 5, the image forming unit 12, the image memory 32, the HDD 92, the fixing unit 13, and the wireless communication unit 73. The operation unit 47, the facsimile communication unit 71, the network interface unit 91, and the speaker 74 are connected to control these units.

  The user information acquisition unit 101 acquires personal information (for example, an ID code) stored in the IC card 4 by NFC communication from the IC card 4 close to the wireless communication unit 73 of the multifunction device 1.

  The user confirmation unit 102 collates the ID code acquired by the user information acquisition unit 101 with the ID code of the user stored in the user information storage unit 111, so that the IC card 4 It is confirmed whether or not the owner is a user who can use the multifunction device 1.

  The setting receiving unit 103 receives various settings from the operator. For example, when the operation unit 47 is operated and “detailed setting” in facsimile transmission is requested, the setting receiving unit 103 displays a detailed setting screen D1 as shown in FIG. Accepts settings made via. The setting accepting unit 103 accepts an input of the other party indicating the other party to which the facsimile transmission image is transmitted based on an operation of the operation unit 47 by the operator, for example.

  The detailed setting screen D1 is formed with an input box B1 for inputting a waiting time T1 for detecting the CED signal, and “operation procedure” for operating the start of facsimile transmission after talking with the other party. Radio buttons R1 and R2 are formed for selecting whether or not to prohibit facsimile transmission when the above is not observed. Only one of the radio buttons R1 and R2 can be selected, and in an initial stage, the radio button R1 is selected (that is, the transmission is prohibited).

  When a numerical value is input to the input box B1 based on the operation of the operation unit 47 by the operator, the setting reception unit 103 inputs “waiting time T1” in the detailed setting information storage unit 114 illustrated in FIG. When the radio button R1 is selected, “0” is written in “Prohibit facsimile transmission” of the detailed setting information storage unit 114, and when the radio button R2 is selected, the value of the detailed setting information storage unit 114 is updated. Write “1” in “Prohibit facsimile transmission”.

  The determination unit 105 determines whether a CED signal is detected by a CED signal detection unit 106 (to be described later) before a predetermined first time elapses after the communication line is connected to the partner. That is, based on the detection result of the CED signal by the CED signal detection unit 106, the determination unit 105 determines whether or not the “operation procedure” of operating the start of facsimile transmission after talking with the other party is observed. Will do.

  The CED signal detection unit 106 detects a CED signal transmitted from another facsimile machine 22 (FIG. 1).

  When the determination unit 105 determines that the CED signal from the partner has not been detected by the determination unit 105, the facsimile transmission image to the partner by the facsimile communication unit 71 is determined. When the determination unit 105 determines that the CED signal has been detected before the first time elapses, the facsimile communication unit 71 transmits the facsimile transmission image to the destination. Control that there is no.

  Next, processing operations performed in the control unit 10 of the multifunction machine 1 when a communication line is connected to another facsimile apparatus 22 by transmission from the facsimile communication unit 71 will be described. FIG. 6 is a flowchart illustrating an example of processing operations performed by the control unit 10.

  The control unit 100 causes the setting reception unit 103 to perform facsimile communication by the facsimile communication unit 71 with respect to the other party received from the operator, so that the communication line with the other facsimile apparatus 22 as the other party can be established. When connected, first, the determination unit 105 sets the call flag F to “0” as an initial setting (S1), starts after resetting the timer T, and starts time measurement (S2).

  The determination unit 105 determines whether a CED signal transmitted from the other party (another facsimile machine 22) is detected by the CED signal detection unit 106 (S3), and determines that no CED signal is detected. If so (NO in S3), the determination unit 105 determines whether the timer T has reached the waiting time T1 (for example, 5 seconds) that is the first time (S4).

  If the determination unit 105 determines that the timer T has reached the standby time T1 (YES in S4), the CED signal is detected even after the standby time T1 has elapsed since the communication line was connected to the destination. In this case, it is assumed that a call is made between the multifunction device 1 and the destination. That is, when determining that the timer T has reached the waiting time T1 (YES in S4), the determining unit 105 sets the call flag F to “1” (S5). On the other hand, when the determination unit 105 determines that the timer T has not reached the waiting time T1 (NO in S4), the process returns to S3.

  If the determination unit 105 determines in S3 that the CED signal is detected by the CED signal detection unit 106 (YES in S3), the facsimile function of the facsimile apparatus 22 as the counterpart is in an automatic reception state. Yes, it is determined that there is no call with the other party, and the determination unit 105 sets the call flag F to “0” and ends this processing operation.

  Next, a processing operation performed in the control unit 10 of the multifunction machine 1 when a facsimile transmission start operation is performed by the operator via the operation unit 47 will be described. FIG. 7 is a flowchart showing an example of operation control of facsimile communication by the multifunction device 1.

  When the setting reception unit 103 receives a facsimile transmission start instruction based on the operation of the operation unit 47 by the operator, the control unit 100 determines the state of the call flag F (S11). That is, based on the state of the call flag F, the control unit 100 determines whether the multifunction device 1 has received a CED signal from another facsimile device 22 as a partner before receiving the instruction to start facsimile transmission. to decide. This is a determination as to whether or not a call has been made between the multifunction device 1 and another facsimile apparatus 22 as the other party before accepting the instruction to start the facsimile transmission.

  When the control unit 100 determines that the call flag F is “0” and no call is made with the other party (NO in S11), the control unit 100 sounds a warning sound (for example, a beep sound) from the speaker 74, In addition to notifying the operator that the above operation procedure has not been followed (S12), the mail address information of the information terminal device 21 used by the administrator is acquired from the administrator information storage unit 113, and the operator's ID code is attached. Then, the network interface unit 91 transmits information indicating that the operation procedure violation has been performed to the information terminal device 21 by electronic mail (S13). Note that the control unit 100 may cause the display unit 473 to display a message indicating that the operation procedure is not followed, together with or instead of the warning sound from the speaker 74.

  Furthermore, the control unit 100 stores the usage information (for example, usage date and time, operator ID code, transmission mode, and operation procedure in violation) in the usage history information storage unit 112 (S14). The transmission mode (automatic transmission / manual transmission) can be determined from the state of the handset 72 at the time of facsimile transmission start operation. When the handset 72 is in the onset state, “automatic transmission” is set, and the offset state is set. Time is “manual transmission”.

  Next, the control unit 100 indicates that the information “prohibition of facsimile transmission” stored in the detailed setting information storage unit 114 indicates a setting for prohibiting facsimile transmission when the above operation procedure is not observed. Is determined (S15). When the control unit 100 determines that the information of “prohibition of facsimile transmission” stored in the detailed setting information storage unit 114 does not indicate a setting for prohibiting facsimile transmission (NO in S15), the facsimile communication unit 71 Then, the facsimile transmission image for the facsimile transmission temporarily stored in the image memory 32 is transmitted to the other facsimile apparatus 22 as the counterpart (S16).

  On the other hand, when the control unit 100 determines that the information “prohibit facsimile transmission” stored in the detailed setting information storage unit 114 indicates a setting for prohibiting facsimile transmission (YES in S15), the facsimile communication is performed. The processing operation is terminated without transmitting the facsimile transmission image by the unit 71 to the other facsimile apparatus 22 as the counterpart.

  In S11, when the control unit 100 determines that the call flag F is “1” and a call is being performed between the multi-function device 1 and another facsimile machine 22 as a partner ( YES in S11), usage information (for example, usage date, operator ID code, transmission mode, no violation of operation procedure) is stored in the usage history information storage unit 112 (S17), and the facsimile communication unit 71 performs the above facsimile transmission. The image is transmitted to the other facsimile machine 22 as the other party (S18).

According to the above embodiment, when it is determined that the operation procedure for starting the facsimile transmission is not followed after a call with the facsimile apparatus 22 as the other party, the following procedure is performed. Can properly deal with violations of operating procedures.
1. The operator can easily notice that the operation procedure for sounding the warning sound is not observed.
2. The administrator (information processing apparatus 21) is notified of the violator of the operation procedure.
The administrator can immediately know that the operation procedure violation has occurred, and can immediately alert the operation procedure violation person.
3. Even if the operation procedure is violated when the administrator is absent, such as at midnight when leaving the history of the operation procedure violation, by referring to the use history information stored in the use history information storage unit 112, the operation procedure is violated. Can be confirmed. FIG. 8 shows an operation procedure violation history screen D2, which is an example when the control unit 100 causes the display unit 473 to display usage history information.
4). Facsimile transmission can be operated according to the prohibited operation procedure.

  In addition, whether or not a call is made with another facsimile machine 22 as a partner is determined based on the detection state of the CED signal, so the systems required for detecting whether or not the operation procedure is followed are compared. This can be realized with a simple configuration. As a result, it is possible to detect that the operation procedure of operating the start of facsimile transmission is not followed after a call with the other party with a simple configuration. Then, it is possible to control whether or not to send a facsimile transmission image to the other party according to the state of compliance with the operation procedure, and reliably prevent erroneous facsimile transmission.

  Next, a case will be described in which it is determined whether or not a call has been made between the operator and the other party by a processing operation different from the processing operation shown in FIG. FIG. 9 is a flowchart showing an example of processing operations performed by the control unit 10.

  The control unit 100 causes the setting reception unit 103 to perform facsimile communication by the facsimile communication unit 71 with respect to the other party received from the operator, so that the communication line with the other facsimile apparatus 22 as the other party can be established. When connected, first, the determination unit 105 sets the call flag F to “0” as an initial setting (S21), starts after resetting the timer T, and starts time measurement (S22).

  The determination unit 105 determines whether or not the CED signal transmitted from the other party (another facsimile apparatus 22) is detected by the CED signal detection unit 106 (S23), and determines that the CED signal is not detected. If (NO in S23), the determination unit 105 determines whether or not the timer T has passed a waiting time T1 (for example, 5 seconds) (S24).

  When the determination unit 105 determines that the timer T has reached the waiting time T1 (YES in S24), the call flag F is set to “1” (S25). On the other hand, when the determination unit 105 determines that the timer T has not reached the waiting time T1 (NO in S24), the process returns to S23.

  If the determination unit 105 determines in S23 that the CED signal has been detected (that is, the facsimile function of the partner facsimile machine 22 is in an automatic reception state) (YES in S23), the determination unit 105 Further, it is determined from the detection result of the CED signal by the CED signal detection unit 106 whether or not the CED signal is interrupted (S26).

  Here, the determination unit 105 reaches a standby time T2 (a predetermined second time, for example, 7 seconds) that is shorter than the standby time T1 from the time measurement start time by the timer T in S22. In the meantime (NO in S26, NO in S27), if it is determined that the CED signal has been interrupted (YES in S26), the determination unit 105 sets the call flag F to “1” (S25). In other words, here, when the CED signal is interrupted, the operator of the facsimile apparatus 22 picks up the handset in the facsimile apparatus 22 as the other party, intentionally cancels the reception status of the facsimile function in the facsimile apparatus 22, Assuming that a call is made with the operator in a state in which a call can be made with the machine 1, the call flag F is set to “1” by the determination unit 105.

  On the other hand, the determination unit 105 determines whether the measurement time by the timer T has reached the standby time T2 (S27) while the CED signal is determined not to be interrupted (NO in S26). When it is determined that the waiting time T2 has been reached (YES in S27), it is determined that the facsimile function of the facsimile apparatus 22 as the counterpart is in the automatic reception state and no call is made with the counterpart. The determination unit 105 sets the call flag F to “0” and ends this processing operation.

  Note that the standby time T2 may be appropriately changed by the operator as in the standby time T1.

  The present invention is not limited to the configuration of the above embodiment, and various modifications can be made. In the above-described embodiment, the multifunction apparatus is described as an embodiment of the facsimile apparatus according to the present invention.
