Description

[0001]
[Industrial application fields]
The present invention relates to a facsimile apparatus capable of communicating in an error correction mode, a control method thereof, and a computer-readable recording medium storing the control program.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, facsimile apparatuses that can communicate in an error correction mode (ECM: error correction mode) are known. A conventional facsimile apparatus capable of communication in the error correction mode can be set to disable the error correction mode according to the user's selection. This is because, when the line condition is bad, there is a user demand to end the communication early even if an error of several lines is allowed, rather than repeating the retransmission to increase the communication time.
[0003]
[Problems to be solved by the invention]
However, if the facsimile apparatus having the error correction mode is selected to disable the error correction mode, a problem occurs when relay communication is performed. For example, when relay broadcast transmission is performed, if the error correction mode is disabled in communication between the two stations due to the setting of the relay instruction station or the distribution station, communication in the normal G3 mode is executed. Here, when a communication error occurs, there is a problem that the distribution station distributes an image damaged by the communication error.
[0004]
In other words, in the past, it was only possible to customize whether to enable or disable the error correction mode, and in order to avoid control that takes into account any further conditions, an error correction mode should be used. There was a problem that the collection mode could not be used.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems and to appropriately control the error correction mode in a facsimile apparatus that can communicate using the error correction mode.
[0006]
[Means for Solving the Problems]
In order to solve the above problems, in the present invention, in a facsimile apparatus capable of communication in an error correction mode, a control method thereof, and a computer-readable recording medium storing the control program thereof,
First registration means or registration step for registering setting information as to whether to enable the error collection mode;
When a specific communication mode is selected and setting information that does not enable the error collection mode in the first registration means or the registration process is registered, Get user response on whether to enable error collection mode and start communication in error collection mode if this user response is affirmative A configuration having a control means or a control process was adopted.
[0011]
Alternatively, it further includes a second registration unit or registration step for registering, as setting information, a communication operation option to be executed when the user's response is a negative response, and setting in the second registration unit or registration step. A configuration is adopted that determines a communication operation to be executed when the user response is a negative response based on the information.
[0012]
Alternatively, as a communication operation option to be executed when the user's response is a negative response in the second registration means or registration step, communication is not performed or communication in which the error correction mode is invalid is performed. A configuration is adopted in which any of the above is registered as setting information.
[0013]

It performs switching and holding a loop. If the signal level (signal line 20a) from the control circuit 20 is “0”, the NCU 2 connects the telephone line 2a to the telephone 4 side. If the signal level is “1”, the NCU 2 connects the telephone line 2a to the facsimile machine. Connect to the side. In the normal state, the telephone line 2a is connected to the telephone 4 side.
[0015]
Reference numeral 6 denotes a hybrid circuit that separates a transmission system signal and a reception system signal, sends a transmission signal from the adder circuit 12 to the telephone line 2a via the NCU2, receives a signal from the other party via the NCU2, The signal is sent to the modem 8 via the signal line 6a.
[0016]
Reference numeral 8 denotes an ITU-T recommendation V.30. 8, V. 21, V.E. 27ter, V.L. 29, V.D. 17, V. 34 is a modulator / demodulator that performs modulation and demodulation based on 34, and each transmission mode is designated by a signal line 20c. The modem 8 receives the signal output to the signal line 20b, outputs the modulated data to the signal line 8a, receives the received signal output to the signal line 6a, and outputs the demodulated data to the signal line 8b. .
[0017]
Reference numeral 10 denotes a circuit that sends out an ANSam signal (communication procedure signal compliant with ITU-T recommendation V8). When a signal level “1” is output to the signal line 20d, the ANSam signal is sent to the signal line 10a. When the signal level “0” is output to the signal line 20d, the signal line 10a operates so as not to output any signal.
[0018]
Reference numeral 12 denotes an addition circuit for adding transmission signals, which inputs information on the signal lines 8a and 10a and outputs the addition result to the signal line 12a.
[0019]
Reference numeral 14 denotes an image data reading circuit, which includes a document conveying system, an optical reading element, and the like. The reading circuit 14 outputs the read data read from the document to the signal line 14a.
[0020]
Reference numeral 16 denotes a recording circuit for recording image data constituted by various recording systems such as a thermal system, an electrophotographic system, and an ink jet system. The recording circuit 16 is used to record one copy (one page per page) when recording a received image or recording an image read by the reading circuit 14 (copying operation).
[0021]
In this specification, the term “recording paper” is used to consistently refer to a medium that receives recording by the recording circuit 16, but the material of the “recording paper” is not necessarily necessarily “paper”. Needless to say, other materials such as a plastic sheet may be used.
[0022]
Reference numeral 18 denotes a memory circuit, which is composed of an arbitrary storage device such as a ROM, a RAM, or a hard disk, and is used for storing various data. In particular, with respect to storage of image information, the memory circuit 18 stores raw information of read image data or encoded image information, and stores raw received image information, decoded image information, or the like. Used for. In the case of this embodiment, the memory circuit 18 corresponds to the computer-readable recording medium of the present invention.

Provided. The key operation information of the operation unit 22 is output to the control circuit 20 through the signal line 22a.
[0024]
Reference numeral 24 denotes a sub-address signal input button. When the button is pressed, a press pulse is generated on the signal line 24a. The actual subaddress is input from the numeric keypad of the operation unit 22 before the subaddress signal input button 24 is pressed (or after the button is pressed). The actual telephone number of the partner station is input separately from the subaddress by a numeric keypad, one-touch key, or speed dial operation of the numeric keypad.
[0025]
The subaddress may be stored in advance together with the telephone number by narrowing a specific separator or the like in the one-touch key of the memory circuit 18 or the registration memory of the speed dial. When a telephone number with a subaddress is read from such a one-touch key or abbreviated dial registration memory, it may be handled in the same manner as when the subaddress signal input button 24 is pressed.
[0026]
In this embodiment, this sub-address is used to specify a memory box of a distribution station that performs relay broadcast. Here, the memory box is a virtual communication device provided in the facsimile machine of the distribution station, and can be designated by a subaddress (such as a subaddress described in ITU-T recommendation T30 or an ISDN subaddress). It shall be. For example, when a sub-address is designated from the other station at the time of an incoming call, the distribution station has a specification registered in a memory box configured in a predetermined memory area (memory circuit 18 in FIG. 1) corresponding to the sub-address. It is configured to execute communication, and it is assumed that relay broadcast processing is registered in the example described later as its specification.
[0027]
Reference numeral 26 denotes a relay broadcast selection button which is pressed when the user selects relay broadcast transmission. When the button is pressed, a pressing pulse is generated on the signal line 26a.
[0028]
Reference numeral 28 denotes a relay broadcast display circuit. This relay broadcast display circuit 28 is for displaying whether or not relay broadcast transmission is selected as a transmission process by operating the relay broadcast selection button 26. When the display circuit 28 displays “relay broadcast”, a signal level “1” is output to the signal line 28a to indicate that relay broadcast transmission is selected. When not displayed, a signal level "0" is output to the signal line 28a to indicate that relay broadcast transmission is not selected. Further, when a clear pulse is generated on the signal line 20f, the display circuit 28 does not display “relay broadcast”. After that, when the relay broadcast selection button 26 is pressed, a press pulse is applied to the signal line 26a. Every time it occurs, the display state of “display” → “not display” → “display”... Is repeated.
[0029]
Reference numeral 30 denotes a registration circuit for registering prohibition of ECM (error correction mode). The control circuit 20 described later registers whether to prohibit the ECM function via the signal line 30a.
[0030]
Reference numeral 32 denotes a registration circuit for registering control at the time of specific mode and user rejection. The registration circuit 32 performs an operation when transmission in a specific mode such as relay broadcast instruction transmission or communication involving transmission of a subaddress signal is selected when the setting for prohibiting the ECM function is registered in the registration circuit 30. Used to register in advance.
[0031]
That is, as described later (fifth and sixth embodiments), when transmission in a specific mode such as relay broadcast instruction transmission or communication involving transmission of a sub-address signal is selected, “error correction mode may be enabled. Is displayed, and if there is a negative response from the operator to this display, communication is not performed (communication is canceled), or communication in normal G3 with error correction mode disabled is performed. Is registered in the registration circuit 32. Registration in the registration circuit 32 is performed by the control circuit 20 via the signal line 32a.
[0032]
Reference numeral 34 denotes a display circuit. As will be described later (fifth and sixth embodiments), for example, based on the information output from the control circuit 20 to the signal line 20g, “error correction mode may be enabled. Is displayed?
[0033]
Reference numeral 20 denotes a control circuit composed of a microprocessor, a memory, and the like, and controls the operation of the entire apparatus. The control circuit 20 controls the operation of the entire apparatus based on a program, which will be described later, stored in a memory such as an internal ROM or the ROM portion of the memory circuit 18. The control performed by the control circuit 20 is roughly as follows.
[0034]
That is, whether or not to enable the error correction mode can be set by registration in the registration circuit 30. If the registration circuit 30 is set to disable the error correction mode, the error correction mode is automatically enabled when a specific communication mode is selected (first to fourth embodiments). As this specific communication mode, in the following embodiments, relay broadcast transmission and communication using a subaddress are considered.
[0035]
Alternatively, when the registration circuit 30 is set to disable the error correction mode in a specific communication mode, the user is asked whether the error correction mode is enabled and the response is an affirmative response. Whether to use the error correction mode is determined according to whether there is a negative response, and if the response is a negative response, the communication mode is changed according to the registration information in the registration circuit 32 ( Fifth and sixth embodiments).
[0036]
Hereinafter, with reference to FIGS. 2 to 11, a plurality of embodiments (first to fifth embodiments) are shown for the control in the above configuration. 2 to 11 show a communication control procedure executed by the control circuit 20. The illustrated procedure is stored in the ROM portion of the memory circuit 18 as a program of the control circuit 20. The parts with the same numbers in FIGS. 2 to 11 are assumed to be continuous at the respective positions.
[0037]
<First Embodiment>
Although ECM communication prohibition can be registered in the registration circuit 30, this embodiment is an example in which ECM communication is executed regardless of the registration state of the registration circuit 30 in a specific communication mode (relay broadcast).
[0038]
In FIG. 2, step S0 represents the beginning of a process started by turning on the power, a predetermined reset operation, or the like. Steps S2 to S8 are initialization processes for setting default (specified values) control conditions, and an event loop during the actual operation of the apparatus is started from step S10.
[0039]
In this initialization process, first, in step S2, ECM communication is registered as valid in the registration circuit 30 via the signal line 30a (default registration state).
[0040]
In step S4, transmission in a specific mode such as relay broadcast instruction transmission or communication involving transmission of a sub-address signal is selected to the registration circuit 32 via the signal line 32a, and “error correction mode may be enabled. If the operator gives a negative response to this display, registration is performed so as not to perform communication (communication stop) (default registration state).
[0041]
In step S6, control is performed so as not to display “Are you sure to enable the error correction mode” on the display circuit 34 via the signal line 20g (nothing is displayed).
[0042]
In step S8, a clear pulse is generated on the signal line 20f, and control is performed so that “relay broadcast” is not displayed on the relay broadcast selection display circuit 28.
[0043]
In step S10, an event loop is entered. In step S10, a signal level “0” is output to the signal line 20a, the CML relay of the NCU 2 is turned off, and the line 2a is connected to the telephone 4 side.
[0044]
In step S12, the signal level “0” is output to the signal line 20d, and the ANSam signal transmission circuit 10 is controlled not to transmit the ANSam signal.
[0045]
In step S14, operation information of the operation unit 22 is input via the signal line 22a, and it is determined whether or not registration in the registration circuit 30 has been selected. When registration in the registration circuit 30 is selected, the process proceeds to step S16, and whether or not to enable ECM communication is registered in the circuit 30 via the signal line 30a according to the operation of the operation unit 22, and the registration circuit 30 is registered. If registration is not selected, the process proceeds to step S18 in FIG.
[0046]
In step S18 of FIG. 3, operation information of the operation unit 22 is input via the signal line 22a, and it is determined whether or not registration in the registration circuit 32 is selected. When registration in the registration circuit 32 is selected, a registration operation for the registration circuit 32 is performed according to the operation of the operation unit 22 in step S20. If registration in the registration circuit 32 is not selected in step S18, the process proceeds to step S22.
[0047]
The registration to the registration circuit 32 in step S20 is an option when the ECM communication prohibition is set in the registration circuit 30 and the user refuses the ECM communication when a specific communication mode is selected (described later). (Refer to the fifth and sixth embodiments). Here, “do not communicate” or “perform normal G3 communication without using ECM” is registered in the registration circuit 32 via the signal line 30a.
[0048]
In step S22, it is determined whether transmission has been selected. If transmission is selected here, the process proceeds to step S26, and if transmission is not selected, the process proceeds to step S24 to execute other known processes (such as copying of a document image or communication management).
[0049]
When transmission is selected, the display state of the display circuit 28 (the selection state of relay broadcast by the relay broadcast selection button 26) is input via the signal line 28a in step S26, and whether or not relay broadcast transmission is selected. Determine whether. If relay broadcast transmission is selected, the process proceeds to step S28. If relay broadcast transmission is not selected, the process proceeds to step S56.
[0050]
In step S28, the operation information of the operation unit 22 is input via the signal line 22a, and the subaddress (calling information) of the memory box of the distribution station in which the target relay broadcast processing is preset as the communication specification is input. .
[0051]
In step S30, the signal level "1" is output to the signal line 20a, the CML relay of the NCU 2 is turned on, the line 2a is connected to the facsimile apparatus side, and designated in step S32 by the subaddress input in step S28. Call the distribution station.
[0052]
In step S34 of FIG. 4, a facsimile communication pre-procedure is performed. Here, information on the presence / absence of the ECM reception function of the partner delivery station and the presence / absence of the relay broadcast transmission function is acquired by exchanging the procedure signals, and stored in a predetermined area of the memory circuit 18.
[0053]
In step S36, it is determined from the result of the facsimile communication pre-procedure in step S34 whether or not the partner machine has a relay broadcast transmission function. If the partner machine has a relay broadcast transmission function, the process proceeds to step S40. If not, the process proceeds to step S38.
[0054]
In step S38, the fact that no communication is performed is displayed on the display circuit 34 via the signal line 20g because the partner machine does not have the relay broadcast transmission function. This display is erased in response to some key operation. After step S38, the process returns to step S10 in FIG.
[0055]
Further, in step S40, it is determined from the result of the facsimile communication pre-procedure in step S34 whether or not the partner machine has an ECM reception function. If the partner machine has an ECM reception function, the process proceeds to step S42, and if not, the process proceeds to step S50 (FIG. 5).
[0056]
In step S42, the registration information of the registration circuit 30 is accessed via the signal line 30a, and it is determined whether or not the ECM communication prohibition is registered in the registration circuit 30. Here, the process proceeds to step S44 regardless of whether the read registration information is prohibited or permitted.
[0057]
In step S44, the remaining facsimile communication pre-procedures are executed. In this case, the other party is instructed to perform relay broadcast transmission, the memory box is designated based on the input subaddress, and the ECM transmission mode is designated. That is, when requesting relay broadcast, even if ECM communication prohibition is registered in the registration circuit 30, it is ignored and ECM communication is executed (see step S42).
[0058]
In step S46, the image signal is read / transmitted. In step S48, the post-facsimile communication procedure is executed, and then the process returns to step S10 in FIG. In step S46, the image signal for requesting relay broadcast is transmitted to the distribution station by ECM communication.
[0059]
On the other hand, if the partner station does not have an ECM communication function in step S40, the remaining pre-facsimile communication pre-procedures are executed in step S50 (FIG. 5). Here, the relay broadcast transmission instruction and the memory box instruction are given, and the ECM transmission is not designated (because the partner station has no function).
[0060]
In step S52, image signal reading / transmission is performed. In step S54, a post-facsimile communication procedure is executed, and the process returns to step S10 in FIG.
[0061]
In FIG. 3 again, if relay broadcast transmission is not selected in step S26, the process proceeds to step S56, a signal level "1" is output to the signal line 20a, the CML relay of the NCU 2 is turned on, and the line 2a Is connected to the facsimile machine. Then, the destination specified in step S58 is called.
[0062]
In step S60, the facsimile communication pre-procedure is executed, and here, the presence or absence of the ECM reception function of the partner machine is stored in a predetermined area of the memory circuit 18.
[0063]
Then, the process proceeds to step S62 in FIG. 5. In this step S62, it is determined whether or not the partner receiver has an ECM reception function. If the partner receiver has an ECM reception function, the process proceeds to step S64, and if not, the process proceeds to step S68.
[0064]
In step S64, the registration information of the registration circuit 30 is accessed via the signal line 30a, and it is determined whether or not ECM communication prohibition is registered in the registration circuit 30.
[0065]
If the ECM communication prohibition is registered in the registration circuit 30, the process proceeds to step S68, and the remaining pre-facsimile communication pre-procedures are executed without designating ECM transmission. If the prohibition of ECM communication is not registered, the process proceeds to step S66, in which ECM transmission is designated and the remaining pre-facsimile communication procedure is executed.
[0066]
In step S70, image signal reading / transmission is performed, and in step S72, a post-facsimile communication procedure is executed.
[0067]
As described above, when relay broadcast transmission is designated, even when ECM communication prohibition is registered, ECM communication is automatically enabled to request relay broadcast transmission, and an image to be distributed is displayed in ECM. It can be transferred by communication, and the problem of distributing a damaged image by relay broadcast can be avoided. Further, since the ECM communication function designation process is automatically performed, it is not necessary to perform a troublesome operation.
[0068]
Needless to say, if relay broadcast transmission is not designated, whether or not to perform ECM communication is determined in accordance with registration in the registration circuit 30.
[0069]
<Second Embodiment>
The first embodiment is an example in which ECM communication is executed regardless of the registration state of the registration circuit 30 in a specific communication mode (relay broadcast), but this specific communication mode is used for communication for transmitting a sub-address signal. It may be replaced. That is, not only the relay broadcast request as in the first embodiment, but in communication performed by transmitting a sub-address signal to the other station, ECM communication is executed regardless of the registration state of the registration circuit 30.
[0070]
Control in this case is shown in FIGS. 6 and 7 as a second embodiment. 6 and 7 show the necessary changes to the control of FIGS.
[0071]
In FIG. 6, step S80 represents Yes in step S22 (FIG. 3). That is, when transmission is selected in step S22, the process proceeds to step S82.
[0072]
In step S82, operation information of the sub address signal input button 24 is input via the signal line 24a, and it is determined whether or not transmission of the sub address signal is selected. If transmission of the sub-address signal is not selected, the process proceeds to step S84 (step S56). If transmission of the sub-address signal is selected, the process proceeds to step S86, and the partner station is based on the operation information of the operation unit 22 via the signal line 22a. Enter the sub address.
[0073]
Step S88 is the same processing as step S30 and step S32. That is, the CML relay of the NCU 2 is turned on and a designated partner station is called.
[0074]
In step S90, a facsimile communication pre-procedure is executed. Here, the presence / absence of the ECM reception function of the partner machine and the presence / absence of the reception function of the subaddress signal are stored in a predetermined area of the memory circuit 18 according to the result of the pre-facsimile communication procedure.
[0075]
In step S92, it is determined whether or not the partner machine has a sub-address signal reception function according to the result of the facsimile communication pre-procedure in step S90. If there is a sub-address signal reception function, the process proceeds to step S98; Proceed to
[0076]
In step S94, the display circuit 34 is controlled via the signal line 20g, and the fact that no communication is performed is displayed on the display circuit 34 because the counterpart device does not have a sub-address signal reception function. This display is erased in response to some key operation. Thereafter, the process proceeds to step S96. Step S96 corresponds to step S10, and therefore the process returns to step S10 (FIG. 2).
[0077]
On the other hand, in step S98, it is determined whether or not the partner machine has an ECM reception function according to the result of the facsimile communication pre-procedure in step S90. If the partner machine has an ECM reception function, the process proceeds to step S100. The process proceeds to S106.
[0078]
In step S100, information of the registration circuit 30 is input via the signal line 30a, and it is determined whether or not ECM communication prohibition is registered in the registration circuit 30. In the present embodiment, the process proceeds to step S102 in FIG. 7 regardless of whether or not ECM communication prohibition is registered in the registration circuit 30.
[0079]
In step S102 of FIG. 7, the remaining pre-facsimile communication pre-procedures are executed. Here, ECM transmission is specified for the partner machine, sub-address signal transmission is specified, and the sub-address signal is further transmitted to the partner machine. That is, in the transmission using the sub address signal, even if the ECM communication prohibition is registered in the registration circuit 30, this is ignored and the ECM communication is executed (see step S100).
[0080]
Step S104 represents step S46 of FIG. That is, thereafter, image signal reading / transmission and post-facsimile communication procedures are executed.
[0081]
On the other hand, if the partner machine does not have an ECM communication function in step S98, the process proceeds to step S106. In step S106, the remaining facsimile communication pre-procedures are executed. Here, the transmission of the sub address signal is designated to the partner machine, and further the sub address signal is transmitted. Here, ECM transmission is not specified. Step S108 represents shifting to step S52 in FIG.
[0082]
Other processes are the same as those in the first embodiment shown in FIGS. Processing in the case of normal transmission is the same as that in the first embodiment, and in normal transmission, ECM communication is controlled according to the registration state of the registration circuit 30.
[0083]
As described above, in the communication performed by transmitting the sub-address signal, the ECM communication can be executed regardless of the registration state of the registration circuit 30. As described above, in communication using sub-addresses, all kinds of transfer processing such as transfer and distribution by e-mail are not limited to the relay broadcast according to the communication specification registered in the memory box on the receiving side. It can be executed by the receiving station. Therefore, by executing the ECM communication regardless of the registration state of the registration circuit 30 in the communication performed by transmitting the sub address signal, it is possible to prevent a damaged image from being transferred through the function of the sub address and the memory box. it can. Further, since the ECM communication function designation process is automatically performed, it is not necessary to perform a troublesome operation.
[0084]
<Third Embodiment>
In the first embodiment, when relay broadcast transmission is selected and the distribution station does not have an ECM reception function, the ECM function is not used, that is, communication is performed using normal G3. If the ECM communication function cannot be used for transmission, the communication may be interrupted.
[0085]
Such control is shown in FIG. 8 as a third embodiment. FIG. 8 shows the changes necessary for the control of FIGS.
[0086]
Step S110 in FIG. 8 represents No in step S40 in FIG. That is, if the partner machine does not have an ECM communication function in step S40, the process proceeds to step S112.
[0087]
In step S112, the display circuit 34 is controlled via the signal line 20g, and it is displayed on the display circuit 34 that relay broadcast transmission is selected but communication is not executed because the partner machine does not have an ECM function. This display is erased in response to some key operation. Thereafter, the process proceeds to step S114. Step S114 corresponds to step S10, and therefore the process returns to step S10 (FIG. 2).
[0088]
As described above, if the ECM communication function cannot be used for relay broadcast transmission, the communication is interrupted to guarantee that the ECM communication function is used when transmitting an image to be distributed in the relay broadcast request to the distribution station. It is possible to prevent a damaged image from being distributed. In addition, the ECM communication function designation process is automatically performed, and there is no need to perform troublesome operations.
[0089]
<Fourth Embodiment>
Regarding the second embodiment, it is conceivable to make the same changes as in the third embodiment. That is, when transmission using the sub-address signal is selected but the receiver does not have an ECM reception function, the communication may be interrupted without executing the normal G3 communication.
[0090]
Such control is shown in FIG. 9 as a fourth embodiment. FIG. 9 shows the changes necessary for the control of FIGS.
[0091]
In FIG. 9, step S120 represents No in step S98 of FIG. That is, if the partner machine does not have an ECM communication function in step S98, the process proceeds to step S122.
[0092]
In step S122, the display circuit 34 is controlled via the signal line 20g to display on the display circuit 34 that transmission of the sub-address signal is selected, but communication is not executed because the counterpart device does not have an ECM function. This display is erased in response to some key operation. Thereafter, the process proceeds to step S124. Step S124 corresponds to step S10. Therefore, the process returns to step S10 (FIG. 2).
[0093]
In this way, when transmitting an image to a partner station in transmission using a sub-address signal that may transfer some data, it is possible to ensure that the ECM communication function is used, and a damaged image is distributed. Can be prevented. In addition, the ECM communication function designation process is automatically performed, and there is no need to perform troublesome operations.
[0094]
<Fifth Embodiment>
In the above first to fourth embodiments, the information of the registration circuit 32 is not used, but the following fifth and sixth embodiments show control using the information of the registration circuit 32.
[0095]
In the present embodiment, when a specific communication mode (relay broadcast in the present embodiment) is selected and the registration circuit 30 is set to invalidate the ECM communication, “the error correction mode may be enabled. The ECM communication is started when an affirmative response to this question is detected. In addition, information for determining processing when the user makes a negative response (or when the user's response is not obtained) is registered in the registration circuit 32 in advance. In other words, when the user makes a negative response to the above question (or when the user's response is not obtained), the registration circuit 32 performs communication that does not communicate or disables ECM communication. , Etc. are stored.
[0096]
The above control is shown as a fifth embodiment in FIG. FIG. 10 shows the changes necessary for the control of FIGS.
[0097]
In FIG. 10, step S130 represents Yes in step S42 of FIG. That is, when relay broadcast is performed, it is confirmed from the result of the facsimile communication pre-procedure that the partner machine has an ECM reception function (step S40 in FIG. 4), and further, ECM communication prohibition is registered in the registration circuit 30. (Step S42), the process proceeds to Step S132.
[0098]
In step S132, the display circuit 34 is controlled via the signal line 20g to display on the display circuit 34 "Are you sure to enable the error correction mode?" Key etc. may be displayed). This display is erased by some key operation, for example, an affirmative or negative response from the user.
[0099]
In step S134, operation information of the operation unit 22 is acquired via the signal line 22a, and a user response is checked. If the user returns an affirmative response by operating a predetermined key of the operation unit 22 or the like, the process proceeds to step S136 (step S44 in FIG. 4), and a negative response (a negative response due to operation of the predetermined key of the operation unit 22 or a predetermined time or more) If no response is given, the process proceeds to step S138.
[0100]
In step S138, the registration information of the registration circuit 32 is input via the signal line 32a, and it is determined whether “not communicating” or “communication without an ECM function” is registered. When “not communicating” is registered, the process proceeds to step S140 (step S112 in FIG. 8), and when “communication without ECM function” is registered, the process proceeds to step S142 (step S50 in FIG. 5). .
[0101]
That is, if the registration information of the registration circuit 32 is “not communicated”, a display indicating that ECM communication is not performed is performed in step S112 of FIG. In step S112, the reason why the ECM communication is not performed is that there is no ECM communication function of the partner machine. This is because the registration information of the registration circuit 32 is “not communicating” or the user gives a negative response. It is desirable to replace it with display information indicating that this has been done. If the registration information of the registration circuit 32 is “communication without ECM function”, in step S50 of FIG. 5, the remaining pre-procedure declares that there is no ECM function and relays in the normal G3 mode without using the ECM function. Send the image to be broadcast to the other device.
[0102]
As described above, when a specific communication mode (relay broadcast in this embodiment) is selected and the setting for disabling ECM communication is performed in the registration circuit 30, the ECM prohibition setting of the registration circuit 30 is ignored. Rather than asking the user whether or not to enable error collection mode and starting an ECM communication when an acknowledgment to this question is detected, the user can In the mode (relay broadcast in the present embodiment), whether to enable or disable the ECM communication can be selected as necessary (after obtaining the user's consent). Further, when the user makes a negative response (or when the user's response is not obtained), “not communicate” or “communication without ECM function” is automatically selected according to the registration of the registration circuit 32. be able to. That is, in this case as well, the ECM prohibition setting of the registration circuit 30 is not simply ignored, but “no communication” or “communication without an ECM function” can be selected, and an appropriate setting is made based on the setting according to the use environment of the user. A specific non-error collection mode can be selected to use a specific communication mode (relay broadcast in this embodiment).
[0103]
<Sixth Embodiment>
Changes similar to those in the fifth embodiment can be added to the second embodiment.
[0104]
That is, in the present embodiment, when a specific communication mode (communication using a sub address in the present embodiment) is selected and the setting for disabling ECM communication is performed in the registration circuit 30, the “error correction mode is set. The user is asked if it can be enabled or not, and if an affirmative response to this question is detected, ECM communication is started. In addition, information for determining processing when the user makes a negative response (or when the user's response is not obtained) is registered in the registration circuit 32 in advance. In other words, when the user makes a negative response to the above question (or when the user's response is not obtained), the registration circuit 32 performs communication that does not communicate or disables ECM communication. , Etc. are stored.
[0105]
The above control is shown as a fifth embodiment in FIG. FIG. 11 shows the necessary changes for the controls of FIGS. 2 to 5 and FIGS.
[0106]
In FIG. 11, step S150 represents Yes in step S100. That is, in this embodiment, when performing communication using the sub-address, it is confirmed from the result of the facsimile communication pre-procedure that the partner machine has an ECM reception function (step S98 in FIG. 6). When the communication prohibition is registered (step S100), the process proceeds to step S152.
[0107]
In step S152, the display circuit 34 is controlled via the signal line 20g to display on the display circuit 34 "Are you sure to enable the error correction mode?" Key etc. may be displayed). This display is erased by some key operation, for example, an affirmative or negative response from the user.
[0108]
In step S154, operation information of the operation unit 22 is acquired via the signal line 22a, and a user response is checked. If the user returns an affirmative response by operating a predetermined key of the operation unit 22 or the like, the process proceeds to step S156 (step S102 in FIG. 7), and a negative response (a negative response due to operation of the predetermined key of the operation unit 22 or a predetermined time or more) If no response is received, the process proceeds to step S158.
[0109]
In step S158, the registration information of the registration circuit 32 is input via the signal line 32a, and it is determined whether “not communicating” or “communication without ECM function” is registered. If “not communicate” is registered, the process proceeds to step S160 (step S122 in FIG. 9), and if “communication without ECM function” is registered, the process proceeds to step S162 (step S106 in FIG. 7). .
[0110]
That is, if the registration information of the registration circuit 32 is “not communicating”, a display indicating that ECM communication is not performed is performed in step S122 of FIG. In step S122, the reason why the ECM communication is not performed is that there is no ECM communication function of the partner machine. This is because the registration information of the registration circuit 32 is “not communicating” or the user gives a negative response. It is desirable to replace it with display information indicating that this has been done. If the registration information of the registration circuit 32 is “communication without ECM function”, in step S106 in FIG. 7, the remaining pre-procedure declares no ECM function and relays in the normal G3 mode without using the ECM function. Send the image to be broadcast to the other device.
[0111]
As described above, when a specific communication mode (communication using a sub-address in this embodiment) is selected and the registration circuit 30 is set to invalidate ECM communication, the ECM prohibition setting of the registration circuit 30 is set. Instead of ignoring the user, the user is asked whether the error correction mode can be enabled, and when an acknowledgment for this question is detected, the user starts an ECM communication. In this communication mode (communication using a sub address in this embodiment), it is possible to select whether to enable or disable the ECM communication (with the user's consent) as required. Further, when the user makes a negative response (or when the user's response is not obtained), “not communicate” or “communication without ECM function” is automatically selected according to the setting of the registration circuit 32. be able to. That is, in this case as well, the ECM prohibition setting of the registration circuit 30 is not simply ignored, but “no communication” or “communication without an ECM function” can be selected, and an appropriate setting is made based on the setting according to the use environment of the user. A specific communication mode (communication using a sub address in this embodiment) can be used by selecting a non-error correction mode.
[0112]
In each of the above embodiments, the “specific communication mode” for performing the control of the present invention is the relay broadcast or the communication using the subaddress, but the transmitted image data is transferred from the partner station to the other station. The “specific communication mode” may be any communication mode that can be transmitted or a mode that requires certainty of information transmission. For example, “specific communication modes” include broadcast transmission by specifying the time and confidential transmission to specific recipients. In these communication modes, an error automatically occurs regardless of the error collection mode prohibition setting. If the collection mode is enabled and image communication is performed, it can be expected that a damaged image can be prevented from being transferred and distributed.
[0113]
In each of the above embodiments, the configuration of the facsimile machine has been shown. However, it goes without saying that the present invention can be implemented not only in the facsimile machine but also in other forms of facsimile machines. For example, the present invention can also be implemented in a configuration in which a FAX modem or the like is externally attached / built in a general-purpose terminal such as a personal computer and facsimile communication is performed by software control. In that case, the control program of the present invention can be stored and supplied not only in the memory circuit 18 described above but also in any computer-readable recording medium such as a hard disk, floppy disk, optical disk, magneto-optical disk or memory card. .
[0114]
【The invention's effect】
As described above, in the facsimile apparatus that can communicate in the error correction mode, the control method thereof, and the computer-readable recording medium storing the control program, a specific communication mode is selected and the error correction mode is enabled. If setting information that is not to be registered is registered, Get user response on whether to enable error collection mode and start communication in error collection mode if this user response is affirmative Since the configuration is adopted, The user is Enable error correction mode for image communication in a specific communication mode But The error correction mode can be appropriately controlled in a specific communication mode, and there is an excellent effect that an image damaged due to a communication error can be prevented from being transferred and distributed.
[0116]
Especially according to the above configuration The user will be able to choose whether to enable or disable ECM communication as needed (with user consent) in each specific communication mode.
[0117]
Alternatively, it further includes a second registration unit or registration step for registering, as setting information, a communication operation option to be executed when the user's response is a negative response, and setting in the second registration unit or registration step. By adopting a configuration that determines a communication operation to be executed when the user response is a negative response based on the information, a specific communication mode can be used based on the setting according to the user's usage environment.
[0118]
Alternatively, as a communication operation option to be executed when the user's response is a negative response in the second registration means or registration step, communication is not performed or communication in which the error correction mode is invalid is performed. If you adopt a configuration that registers any of the above as setting information, instead of simply ignoring the error collection mode prohibition setting, select an appropriate non-error collection mode based on the setting that matches the user's usage environment. A specific communication mode can be used.
