The storage medium is characterized by storing a program including a recording control program for causing the recording means to execute a series of recordings.
[0036]
  Next, the main points of the operation of the facsimile apparatus configured as described above will be described. In this facsimile apparatus, the operation at the time of facsimile reception is determined according to the combination of the mark flag, backup flag, and presence / absence of disturbance light stored in the EEPROM 6. These mark flag and backup flag can be switched on and off alternately by operating the operation unit 13. For example, the mark flag is switched from on to off or from off to on by simultaneously pressing two predetermined key switches provided in the operation unit 13. Similarly, the backup flag is switched from on to off or from off to on by simultaneously pressing the other two key switches. However, the mark flag switching operation is disclosed to all users according to the instruction manual or the like, but the backup flag switching operation is disclosed only to a specific user who has been charged individually. This is because it is considered that there are very few users who do not require backup of received data. When the facsimile apparatus is shipped from the factory, both the mark flag and the backup flag are set to on.
[0037]
  When both the mark flag and the backup flag are on, that is, “1”, if the ambient light does not enter the mark sensor 15 at the time of the incoming call, the recording unit 12 receives the received image with black ink in the received image recording area on the recording paper. And an ink empty mark is recorded with black ink at a predetermined position at the rear end portion outside the received image recording area on the recording paper. If the ink empty mark is detected by the mark sensor 15 and can be detected normally, the same operation is repeated until the last page while confirming the presence or absence of disturbance light for each page of the received data. If ambient light enters, it may not be detected even though the ink empty mark is recorded normally.
[0038]
  If the ink empty mark cannot be detected normally despite the absence of disturbance light, the page is switched to substitute reception, and the received data is stored in the RAM 3 as backup data without recording by the recording unit 12. . Then, after the reception is completed, a display indicating that the ink flow path of black ink should be cleaned is displayed on the display screen of the display unit 14. If the user performs an operation for cleaning the ink flow path of black ink on the operation unit 13, the ink flow path of black ink is automatically cleaned, and then the backup data received on behalf of the ink is empty. Recording is automatically performed by the recording unit 12 together with the mark. At this time, if the ink empty marks on all pages can be normally detected, the automatically recorded backup data is erased from the RAM 3. If there is a page for which the incremental mark could not be detected normally, a display for inquiring the user whether or not the recording was performed normally is displayed on the display screen of the display unit 14. If the user performs an input operation to the effect that the recording has been normally performed on the operation unit 13, the backup data stored in the RAM 3 is deleted by proxy reception.
[0039]
  If ambient light is detected during recording of the received data, the next page is switched to substitute reception, and the received data is stored in the RAM 3 as backup data without recording by the recording unit 12. Then, after the reception is completed, the backup data stored in the RAM 3 is automatically recorded by the recording unit 12 together with the ink empty mark. At this time, if the ink empty marks on all pages can be normally detected, the automatically recorded backup data is erased from the RAM 3.
[0040]
  If disturbance light enters the mark sensor 15 at the time of an incoming call, the received data is recorded by the recording unit 12 over the entire page together with the ink empty mark, and at the same time stored in the RAM 3 as backup data. Then, after the reception is completed, a display for inquiring the user whether or not the recording has been normally performed is displayed on the display screen of the display unit 14. If the user performs an input operation indicating that the recording has been normally performed on the operation unit 13, the backup data stored in the RAM 3 is erased simultaneously with the recording.
[0041]
  When the mark flag is on, ie, “1”, and the backup flag is off, ie, “0”, if there is no intrusion of disturbance light into the mark sensor 15 when receiving an incoming call, the recording unit 12 causes A received image is recorded with ink, and an ink empty mark is recorded with black ink at a predetermined position on the recording paper. If the ink empty mark is detected by the mark sensor 15 and can be detected normally, the same operation is repeated until the last page while confirming the presence or absence of disturbance light for each page of the received data.
[0042]
  If the ink empty mark cannot be detected normally despite the absence of disturbance light, the page is switched to substitute reception, and the received data is stored in the RAM 3 as backup data without recording by the recording unit 12. . Then, after the reception is completed, a display indicating that the ink flow path of black ink should be cleaned is displayed on the display screen of the display unit 14. If the user performs an operation for cleaning the ink flow path of black ink on the operation unit 13, the ink flow path of black ink is automatically cleaned, and then the backup data received on behalf of the ink is empty. Recording is automatically performed by the recording unit 12 together with the mark. At this time, if the ink empty marks on all pages can be normally detected, the automatically recorded backup data is erased from the RAM 3. If there is a page for which the incremental mark could not be detected normally, a display for inquiring the user whether or not the recording was performed normally is displayed on the display screen of the display unit 14. If the user performs an input operation to the effect that the recording has been normally performed on the operation unit 13, the backup data stored in the RAM 3 is deleted by proxy reception.
[0043]
  If ambient light is detected during reception data recording, recording of the reception data and ink empty mark by the recording unit 12 is continued to the last page without detecting the ink empty mark from the next page. At this time, backup is not performed.
[0044]
  If disturbance light enters the mark sensor 15 at the time of the incoming call, the received data and the ink empty mark are recorded by the recording unit 12 over the entire page. At this time, the ink empty mark is not detected and the backup is not performed.
[0045]
  When the mark flag is off, that is, “0” and the backup flag is on, that is, “1”, the received data is recorded by the recording unit 12 over the entire page regardless of the presence or absence of disturbance light, and at the same time, is stored in the RAM 3 as backup data. Store. At this time, ink empty marks are not recorded. Then, after the reception is completed, a display for inquiring the user whether or not the recording has been normally performed is displayed on the display screen of the display unit 14. If the user performs an input operation indicating that the recording has been normally performed on the operation unit 13, the backup data stored in the RAM 3 is erased simultaneously with the recording.
[0046]
  When both the mark flag and the backup flag are off, that is, “0”, the received data is recorded by the recording unit 12 over the entire page regardless of the presence or absence of ambient light. At this time, ink empty marks are not recorded. Also, no backup is performed.
[0047]
  The above operation will be described in more detail.
[0048]
  First, the procedure of reception processing will be described with reference to the flowchart shown in FIG. The CPU 1 determines whether there is a call (S1). Specifically, the CPU 1 monitors the NCU 2 to check whether a call signal is input from the switching center via the telephone line 21.
[0049]
  If there is a call (S1: YES), the CPU 1 controls the NCU 2 to close the line (S2). Then, the CPU 1 determines whether or not it is facsimile reception (S3). Specifically, the data input to the modem 4 via the telephone line 21 and the NCU 2 and demodulated by the modem 4 is monitored to check whether the received information is facsimile communication information.
[0050]
  If it is facsimile reception (S3: YES), the CPU 1 determines whether or not the mark flag is on (S4). Specifically, the CPU 1 reads a mark flag stored in a predetermined area of the EEPROM 6 and checks whether or not the content is “1”. This mark flag indicates whether or not to use the ink empty mark, and is set to ON at the time of shipment from the factory, and when the user performs a predetermined key operation on the operation unit 13, The on state and the off state can be switched.
[0051]
  If the mark flag is on (S4: YES), the CPU 1 determines whether or not the backup flag is on (S5). Specifically, the CPU 1 reads a backup flag stored in a predetermined area of the EEPROM 6 and checks whether or not the content is “1”. This backup flag indicates whether or not the facsimile reception data is stored in the RAM 3 under a predetermined condition. The backup flag is set to ON at the shipment stage from the factory, and a predetermined key operation is performed on the operation unit 13. Although it is possible to switch between the on state and the off state by applying, the key operation for that purpose is disclosed individually only when there is a request from each user.
[0052]
  If the backup flag is on (S5: YES), the CPU 1 executes the first control (S6) and ends this routine. Specific contents of the first control will be described later.
[0053]
  If the backup flag is not on in S5 (S5: NO), the CPU 1 executes the second control (S7) and ends this routine. Specific contents of the second control will be described later.
[0054]
  If the mark flag is not on in S4 (S4: NO), the CPU 1 determines whether or not the backup flag is on (S8).
[0055]
  If the backup flag is on (S8: YES), the CPU 1 executes the third control (S9) and ends this routine. Specific contents of the third control will be described later.
[0056]
  If the backup flag is not on in S8 (S8: NO), the CPU 1 executes the fourth control (S10) and ends this routine. Specific contents of the fourth control will be described later.
[0057]
  If it is not facsimile reception in S3 (S3: NO), it is reception of an audio signal, so the CPU 1 executes audio processing (S11) and ends this routine. In this voice processing, for example, in the answering machine mode, the digital voice data corresponding to the response message stored in the RAM 3 is read out, converted into an analog voice signal by the codec 8, and sent to the telephone line 21 via the NCU 2. At the same time, the analog voice signal corresponding to the message message input to the NCU 2 via the telephone line 21 is converted into digital voice data by the codec 8 and stored in the RAM 3, which is well known. Since there is, specific explanation is omitted.
[0058]
  In S1, if there is no call (S1: NO), the process returns to S1 and waits for a call.
[0059]
  FIGS. 3 and 4 are flowcharts for explaining the procedure of the first control process in S6 of FIG. 2. In the first control process, the CPU 1 first determines the presence or absence of disturbance light (S21). Specifically, the CPU 1 monitors the detection output from the mark sensor 15 in a state in which no recording paper exists at the detection position by the mark sensor 15 and the light source such as the light emitting diode of the mark sensor 15 is turned off. Then, it is checked whether or not the detection output exceeds a predetermined value.
[0060]
  If ambient light is not present (S21: NO), the CPU 1 determines whether or not the count value of the dot counter is equal to or less than a predetermined value (S22). Specifically, the CPU 1 reads the count value of the dot counter corresponding to the black ink from the EEPROM 6 and checks whether the value is equal to or less than the second threshold value. The dot counter is realized, for example, by monitoring the print data supplied from the CPU 1 to the recording unit 12, calculating the cumulative value of the number of dots ejected for each color of ink, and storing it in the EEPROM 6. The count values of these dot counters are automatically reset every time the ink cartridge is replaced. The count values of these dot counters are managed using the first threshold value and the second threshold value. For example, if the count value corresponding to black ink exceeds the first threshold value, the CPU 1 displays the display unit. 14 is displayed on the display screen to the effect that the remaining black ink is low. If the second threshold value, which is larger than the first threshold value, is exceeded, the CPU 1 displays on the display screen of the display unit 14 that black ink has been exhausted and prohibits recording with black ink.
[0061]
  If the count value of the dot counter is equal to or smaller than the predetermined value (S22: YES), the CPU 1 records the received data (S23). Specifically, the CPU 1 supplies the reception data demodulated by the modem 4 and decoded by the codec 8 to the recording unit 12 via the gate array 7, and the received image for one band is recorded on the recording paper with black ink. Print on top. Here, one band refers to the width in the sub-scanning direction recorded by a print head having a large number of nozzles moving once in the main scanning direction.
[0062]
  Then, the CPU 1 determines whether or not the recording for one page has been completed (S24).
[0063]
  If the recording for one page is completed (S24: YES), the CPU 1 controls the recording unit 12 to record the ink empty mark at a predetermined position on the recording paper (S25). Then, the CPU 1 reads the ink empty mark (S26). Specifically, the CPU 1 checks the value of the detection data input from the mark sensor 15 via the gate array 7 when the ink empty mark on the recording paper reaches the detection position by the mark sensor 15. Then, the CPU 1 determines whether or not the ink empty mark has been normally read (S27). Specifically, the CPU 1 checks whether or not the value of the detection data read in S26 is less than a predetermined value.
[0064]
  If the incremental mark can be read normally (S27: YES), the CPU 1 determines whether or not the recording of the received data has been completed for all pages (S28).
[0065]
  If the recording of the received data is not completed for all pages (S28: NO), that is, if there is a page to be recorded next, the CPU 1 determines the presence or absence of disturbance light (S29).
[0066]
  If there is ambient light (S29: YES), the CPU 1 determines whether or not the memory is full (S30). Specifically, the CPU 1 checks whether the free space of the RAM 3 is a predetermined value or more.
[0067]
  If the memory is not full (S30: NO), the CPU 1 stores the received data in the RAM 3 as backup data (S32). Specifically, the CPU 1 causes the DMAC 9 to store the received data demodulated by the modem 4 and decoded by the codec 8 in the RAM 3 by a predetermined byte. In other words, if ambient light enters during reception, recording is stopped from that page and switching to memory substitution reception is performed. When the received data is stored in the RAM 3 as backup data in this way, information on whether the received data has been recorded or not recorded, as well as various types of information such as the transmission source and reception time of the received data, are stored in the RAM 3. If the received data is recorded later, the information is rewritten from unrecorded to recorded. Then, the CPU 1 determines whether or not the received data for one page is stored in the RAM 3 (S33).
[0068]
  If the reception data for one page is stored in the RAM 3 (S33: YES), the CPU 1 determines whether the reception data for all pages is stored in the RAM 3 (S34).
[0069]
  If the reception data of all pages is stored in the RAM 3 (S34: YES), the CPU 1 opens the line (S35). Specifically, the CPU 1 controls the NCU 2 to open the telephone line 21. Then, the CPU 1 determines whether or not the count value of the dot counter is equal to or less than a predetermined value (S36).
[0070]
  If the count value of the dot counter is equal to or smaller than the predetermined value (S36: YES), the CPU 1 records the backup data stored in the RAM 3 in S32 (S37). Specifically, the CPU 1 reads the backup data stored in the RAM 3 and supplies it to the recording unit 12 via the gate array 7 to print the received image for one band on the recording paper with black ink.
[0071]
  Then, the CPU 1 determines whether or not the recording for one page has been completed (S38).
[0072]
  If the recording for one page has been completed (S38: YES), the CPU 1 controls the recording unit 12 to record the ink empty mark at a predetermined position on the recording paper (S39). Then, the CPU 1 reads the ink empty mark (S40). Then, the CPU 1 determines whether or not the ink empty mark has been normally read (S41).
[0073]
  The intempty mark must be read correctlyThisIf this is the case (S41: NO), the CPU 1 sets the content of the flag A to “1” (S42). Specifically, the CPU 1 reads the flag A from a predetermined area of the EEPROM 6, writes “1” if the content is “0”, and leaves it as it is if it is “1”. This flag A indicates whether or not the ink empty mark has been normally read during the recording of the reception data received by proxy, and is stored in a predetermined area of the EEPROM 6. Then, the CPU 1 determines whether or not the recording of the received reception data has been completed for all pages (S43).
[0074]
  If the recording of the received data has been completed for all pages (S43: YES), the CPU 1 determines whether or not the content of the flag A is “0” (S44). If the content of the flag A is not “0” (S44: NO), it means that the ink empty mark could not be read normally at least once, and the received data received by proxy was not recorded normally. Therefore, the CPU 1 sets the content of the flag A to “0” without erasing the received data from the RAM 3 (S45), and ends this routine.
[0075]
  If the content of the flag A is “0” in S44 (S44: YES), this means that the ink empty mark has been read normally over all pages, and it is considered that the received data received on behalf of the proxy has been recorded normally. The CPU 1 deletes the present backup data (S46) and ends this routine. More specifically, the CPU 1 erases the received data that has been received from the RAM 3 from the RAM 3.
[0076]
  In S43, if the recording of the received data is not completed for all pages (S43: NO), that is, if there is a page to be recorded next, the process returns to S36 to start the recording preprocessing.
[0077]
  If the ink empty mark can be read normally in S41 (S41: YES), it is not necessary to set the flag A to “1”, so S42 is skipped and the process proceeds to S43.
[0078]
  If the recording for one page is not completed in S38 (S38: NO), the process returns to S37 to continue the recording.
[0079]
  If the count value of the dot counter is not less than or equal to the predetermined value in S36 (S36: NO), the CPU 1 displays on the display screen of the recording unit 12 that the black ink has run out (S47). Then, the CPU 1 sets a recording prohibition mode (S48), and proceeds to S45. When the record prohibit mode is set, when facsimile data is received, all of the data is received by proxy, and even if all recorded backup data in the RAM 3 is erased, the free memory capacity does not exceed a predetermined value. Refusal to receive facsimile data. This recording prohibition mode is canceled by cleaning the ink flow path of black ink that is automatically executed after the user replaces the black ink cartridge.
[0080]
  If the received data for all pages is not stored in the RAM 3 in S34 (S34: NO), that is, if there is received data for the next page to be stored, the process returns to S30 and preprocessing for storing the received data is started. To do.
[0081]
  In S33, if reception data for one page is not stored in the RAM 3 (S33: NO), the process returns to S32 and storage of the reception data is continued.
[0082]
  If the memory is full in S30 (S30: YES), the process cannot proceed to S35, and the process proceeds to S35.
[0083]
  If there is no disturbing light in S29 (S29: NO), the process returns to S22 and pre-recording processing is started.
[0084]
  In S28, if the recording of the received data is completed for all pages (S28: YES), the CPU 1 releases the line (S49). Then, the CPU 1 deletes all recorded backup data (S50), and ends this routine. Specifically, the CPU 1 reads information on the received data stored in the RAM 3 from the RAM 3, individually determines whether the received data is recorded or unrecorded, and records all the recorded data. Erase from RAM3.
[0085]
  In S27, if the ink empty mark cannot be read normally (S27: NO), the ink empty mark cannot be normally read even though there is no ambient light, so it can be determined that the ink is clogged. The ink clogging process is executed (S51), and this routine is terminated. Details of the ink clogging process will be described later.
[0086]
  If the recording for one page is not completed in S24 (S24: NO), the process returns to S23 to continue the recording.
[0087]
  In S22, if the count value of the dot counter is not less than or equal to the predetermined value (S22: NO), the black ink is out of ink, so the CPU 1 executes the ink out process (S52) and ends this routine. Details of this ink out process will be described later.
[0088]
  In S21, if ambient light is present (S21: YES), the CPU 1 determines whether or not the memory is full (S53).
[0089]
  If the memory is not full (S53: NO), the CPU 1 determines whether or not the count value of the dot counter is equal to or less than a predetermined value (S55).
[0090]
  If the count value of the dot counter is equal to or smaller than the predetermined value (S55: YES), the CPU 1 records the received data and stores it (S56). Specifically, the CPU 1 supplies the reception data demodulated by the modem 4 and decoded by the codec 8 to the recording unit 12 through the gate array 7, and the received image is recorded on the recording paper by the recording unit 12. At the same time, a predetermined byte is stored in the RAM 3 by the DMAC 9. Then, the CPU 1 determines whether or not the received data for one page has been recorded and stored (S57).
[0091]
  If reception data for one page is recorded and stored (S57: YES), the CPU 1 controls the recording unit 12 to record an ink empty mark at a predetermined position on the recording paper (S58). Then, the CPU 1 determines whether or not the received data of all pages has been recorded and stored (S59).
[0092]
  If the reception data of all pages is recorded and stored (S59: YES), the CPU 1 opens the line (S60). Then, the CPU 1 executes a recording result inquiry process (S61) and ends this routine. Details of the recording result inquiry process will be described later.
[0093]
  If the received data of all pages is not recorded and stored in S59 (S59: NO), that is, if there is received data of the next page to be recorded and stored, the process returns to S53 to record and store the next page. The preprocessing of is started.
[0094]
  If the received data for one page is not recorded and stored in S57 (S57: NO), the process returns to S56 to continue recording and storing the received data.
[0095]
  In S55, if the count value of the dot counter is not less than or equal to the predetermined value (S55: NO), the ink has run out of black ink, so the CPU 1 executes the ink running out process (S62) and ends this routine. Details of this ink out process will be described later.
[0096]
  If the memory is full in S53 (S53: YES), the CPU 1 determines whether or not the recorded backup data is stored in the RAM 3 (S63). If the recorded backup data is stored in the RAM 3 (S63: YES), the CPU 1 erases one recorded backup data from the RAM 3 (S64), and returns to S53. If the recorded backup data is not stored in the RAM 3 (S63: NO), the CPU 1 controls the NCU 2 to release the line (S65) and terminates this routine.
[0097]
  In this way, when both the mark flag and the backup flag are on, if there is no ambient light at the time of incoming call, the ink empty mark is recorded, and the received data is recorded while checking whether the ink empty mark can be read correctly. I will do it. If the ink empty mark can be read correctly over all pages, it is considered that ink clogging has not occurred. Therefore, if there is recorded backup data stored in the RAM 3, all of them are erased.
[0098]
  If the ink empty mark cannot be read normally even though there is no ambient light, it is assumed that an ink clogging has occurred and switching to proxy reception is performed.
[0099]
  If ambient light enters during recording, it switches to alternate reception and automatically records after reception ends. This is because disturbance light that has entered during recording is considered to have low continuity, and there is a high possibility that disturbance light will disappear after the end of reception.
[0100]
  If there is disturbance light at the time of the incoming call, it is recorded while backing up from the first page. This is because the ink empty mark cannot be read normally if ambient light is present.
[0101]
  FIG. 5 is a flowchart for explaining the procedure of the second control process in S7 of FIG. 2. In the second control process, first, the CPU 1 determines the presence or absence of ambient light (S71).
[0102]
  If ambient light does not exist (S71: NO), the CPU 1 determines whether the count value of the dot counter is equal to or less than a predetermined value (S72).
[0103]
  If the count value of the dot counter is equal to or smaller than the predetermined value (S72: YES), the CPU 1 records the received data (S73). Then, the CPU 1 determines whether or not the recording for one page has been completed (S74).
[0104]
  If the recording for one page is completed (S74: YES), the CPU 1 controls the recording unit 12 to record the ink empty mark at a predetermined position on the recording paper (S75). Then, the CPU 1 reads the ink empty mark (S76). Then, the CPU 1 determines whether or not the ink empty mark has been read normally (S77).
[0105]
  If the incremental mark can be read normally (S77: YES), the CPU 1 determines whether or not the recording of the received data has been completed for all pages (S78).
[0106]
  If the recording of the received data has been completed for all pages (S78: YES), the CPU 1 releases the line (S79) and ends this routine.
[0107]
  In S78, if the recording of the received data is not completed for all pages (S78: NO), that is, if there is received data for the next page to be recorded, the process returns to S71 to start the preprocessing for recording the next page. To do.
[0108]
  In S77, if the ink empty mark cannot be read normally (S77: NO), the CPU 1 executes the ink clogging process (S80) and ends this routine. Details of the ink clogging process will be described later.
[0109]
  If the recording for one page is not completed in S74 (S74: NO), the process returns to S73 to continue the recording.
[0110]
  If the count value of the dot counter is not less than or equal to the predetermined value in S72 (S72: NO), the black ink is out of ink, so the CPU 1 executes the ink out process (S81) and ends this routine. Details of this ink out process will be described later.
[0111]
  If disturbance light is present in S71 (S71: YES), the CPU 1 determines whether or not the count value of the dot counter is equal to or smaller than a predetermined value (S82).
[0112]
  If the count value of the dot counter is equal to or smaller than the predetermined value (S82: YES), the CPU 1 records the received data (S83). Then, the CPU 1 determines whether or not reception data for one page has been recorded (S84).
[0113]
  If the reception data for one page is recorded (S84: YES), the CPU 1 controls the recording unit 12 to record the ink empty mark at a predetermined position on the recording paper (S85). Then, the CPU 1 determines whether or not received data for all pages has been recorded (S86).
[0114]
  If the reception data of all the pages has been recorded (S86: YES), the process proceeds to S79 to release the line.
[0115]
  If the received data for all pages is not recorded in S86 (S86: NO), that is, if there is received data for the next page to be recorded, the process returns to S82 to start the preprocessing for recording the next page.
[0116]
  If the received data for one page is not recorded in S84 (S84: NO), the process returns to S83 to continue recording.
[0117]
  In S82, if the count value of the dot counter is not less than or equal to the predetermined value (S82: NO), the CPU 1 executes the ink out process (S87) and ends this routine. Details of this ink out process will be described later.
[0118]
  In this way, when the mark flag is on and the backup flag is off, recording is performed without backup regardless of the presence or absence of ambient light. Then, only when the ink empty mark cannot be normally read although there is no disturbance light, switching to the alternate reception is performed. This is to respect the intention of the user who dares to set the backup flag off without desiring to back up.
[0119]
  FIG. 6 is a flowchart for explaining the procedure of the third control process in S9 of FIG. 2. In the third control process, first, the CPU 1 determines whether or not the memory is full (S91).
[0120]
  If the memory is not full (S91: NO), the CPU 1 determines whether or not the count value of the dot counter is equal to or less than a predetermined value (S93).
[0121]
  If the count value of the dot counter is equal to or less than the predetermined value (S93: YES), the CPU 1 records the received data and stores it simultaneously (S94). Then, the CPU 1 determines whether or not reception data for one page has been recorded and stored (S95).
[0122]
  If the reception data for one page is recorded and stored (S95: YES), the CPU 1 determines whether the reception data for all pages is recorded and stored (S96).
[0123]
  If the received data of all pages is recorded and stored (S96: YES), the CPU 1 opens the line (S97). Then, the CPU 1 executes a recording result inquiry process (S98) and ends this routine. Details of the recording result inquiry process will be described later.
[0124]
  If the received data of all pages is not recorded and stored in S96 (S96: NO), that is, if there is received data of the next page to be recorded and stored, the process returns to S91 to record and store the next page. The preprocessing of is started.
[0125]
  If the received data for one page is not recorded and stored in S95 (S95: NO), the process returns to S94 to continue recording and storing the received data.
[0126]
  In S93, if the count value of the dot counter is not less than or equal to the predetermined value (S93: NO), the black ink is out of ink, so the CPU 1 executes the ink out process (S99) and ends this routine. Details of this ink out process will be described later.
[0127]
  If the memory is full in S91 (S91: YES), the CPU 1 determines whether or not the recorded backup data is stored in the RAM 3 (S92a). If the recorded backup data is not stored in the RAM 3 (S92a: NO), the CPU 1 controls the NCU 2 to release the line and terminates this routine. If recorded backup data is stored in the RAM 3 (S92a: YES), the CPU 1 erases one recorded backup data from the RAM 3 (S92c), and returns to S91.
[0128]
  Thus, when the mark flag is off and the backup flag is on, all received facsimile data is stored in the RAM 3 as backup data regardless of the presence or absence of ambient light. Of course, the ink empty mark is not recorded.
[0129]
  FIG. 7 is a flowchart for explaining the procedure of the fourth control process in S10 of FIG. 2. In the fourth control process, first, the CPU 1 determines whether or not the count value of the dot counter is equal to or less than a predetermined value. Is determined (S101).
[0130]
  If the count value of the dot counter is equal to or smaller than the predetermined value (S101: YES), the CPU 1 records the received data (S102). Then, the CPU 1 determines whether or not reception data for one page has been recorded (S103).
[0131]
  If reception data for one page has been recorded (S103: YES), the CPU 1 determines whether reception data for all pages has been recorded (S104).
[0132]
  If the reception data of all pages has been recorded (S104: YES), the CPU 1 opens the line (S105), and this routine is finished.
[0133]
  In S104, if the reception data for all pages is not recorded (S104: NO), that is, if there is reception data for the next page to be recorded, the process returns to S101 to start preparation for recording the next page.
[0134]
  If the received data for one page is not recorded in S103 (S103: NO), the process returns to S102 to continue recording and storing the received data.
[0135]
  In S101, if the count value of the dot counter is not less than the predetermined value (S101: NO), the black ink is out of ink, so the CPU 1 executes the ink out process (S106) and ends this routine. Details of this ink out process will be described later.
[0136]
  As described above, when both the mark flag and the backup flag are OFF, the ink empty mark is not recorded and the backup is not performed regardless of the presence or absence of ambient light.
[0137]
  FIG. 8 is a flowchart for explaining the procedure of the recording result inquiry process in S61 of FIG. 3 and S98 of FIG. 6. In the recording result inquiry process, the CPU 1 first controls the display unit 14 to display the display unit. A display for inquiring the user whether the recording result is satisfactory is displayed on the display screen 14 (S111). Specifically, the CPU 1 causes the display as shown in FIG. 15A and the display as shown in FIG. 15B to be alternately displayed at predetermined positions on the display screen of the display unit 14 every predetermined time. Then, the CPU 1 determines whether or not the user has performed an input operation indicating that the recording is good (S112). Specifically, the CPU 1 monitors an operation signal from the operation unit 13 to check whether the user has pressed the numeric key “1”.
[0138]
  If the input operation indicating that the recording is good is not performed by the user (S112: NO), the CPU 1 determines whether or not the input operation indicating that the recording is bad is performed by the user (S113). Specifically, the CPU 1 monitors an operation signal from the operation unit 13 to check whether or not the user has pressed the “2” numeric keypad.
[0139]
  If the user checks the received image recorded on the recording paper and performs an input operation indicating that the recording is bad (S113: YES), the CPU 1 controls the display unit 14 and the recording result is good. The display for inquiring the user whether or not there is is deleted (S114), and this routine is terminated.
[0140]
  In S113, if the input operation indicating that the recording is bad is not performed (S113: NO), the process returns to S112 and waits for the input operation by the user.
[0141]
  In S112, if the user has performed an input operation indicating that the recording is good (S112: YES), the CPU 1 deletes the backup data (S115), and proceeds to S114. Specifically, the CPU 1 erases the received data stored in the RAM 3 in S56 of FIG. 3 or S94 of FIG.
[0142]
  As described above, when recording and storing are performed simultaneously, the user is inquired about the print result, and if the print result is good, the backup data is erased so that useless backup data does not stay in the RAM 3. ing.
[0143]
  FIG. 9 is a flowchart for explaining the procedure of the ink clogging process in S51 of FIG. 3 or S80 of FIG. 5. In the ink clogging process, first, the CPU 1 determines whether or not the memory is full (S121). . Specifically, the CPU 1 checks whether the free space of the RAM 3 is a predetermined value or more.
[0144]
  If the memory is not full (S121: NO), the CPU 1 stores the received data in the RAM 3 (S123). Specifically, first, the CPU 1 transfers the received data of the page where the ink empty mark could not be normally read from the buffer area of the RAM 3 to the backup data storage area. The received data demodulated and decoded by the codec 8 is stored in the RAM 3 by a predetermined byte by the DMAC 9. That is, the fact that the ink empty mark could not be read normally indicates that there is a high possibility that ink clogging has occurred in the middle of the page. Therefore, the received data of the recorded page itself is also stored in the RAM 3 as backup data. Is stored. Then, the CPU 1 determines whether or not the received data for one page is stored in the RAM 3 (S124).
[0145]
  If the reception data for one page is stored in the RAM 3 (S124: YES), the CPU 1 determines whether the reception data for all pages is stored in the RAM 3 (S125).
[0146]
  If the reception data of all pages is stored in the RAM 3 (S125: YES), the CPU 1 opens the line (S126). Specifically, the CPU 1 controls the NCU 2 to open the telephone line 21. Then, the CPU 1 controls the display unit 14 to display that ink clogging has occurred in a predetermined area on the display screen of the display unit 14 (S127). Then, the CPU 1 sets a recording prohibition mode (S128) and ends this routine. When the record prohibit mode is set, when facsimile data is received, all of the data is received by proxy, and even if all recorded backup data in the RAM 3 is erased, the free memory capacity does not exceed a predetermined value. Refusal to receive facsimile data. In this recording prohibit mode, the black ink ink flow path that is executed based on a predetermined key operation on the operation unit 13 by the user, or the black ink that is executed every predetermined time during the power-on period of the facsimile apparatus. It is released by cleaning the ink flow path.
[0147]
  If the received data for all pages is not stored in the RAM 3 in S125 (S125: NO), that is, if there is received data for the next page to be stored, the process returns to S121 to start preprocessing for storing the next page. To do.
[0148]
  If the received data for one page is not stored in the RAM 3 in S124 (S124: NO), the process returns to S123 and the storage is continued.
[0149]
  If the memory is full in S121 (S121: YES), the process cannot proceed to S126, and the process proceeds to S126.
[0150]
  As described above, when the ink empty mark cannot be read normally, it is determined that the ink flow path of black ink is clogged, and the user is prompted to perform an operation for cleaning the ink flow path of black ink. I have to.
[0151]
  FIG. 10 is a flowchart for explaining the procedure of the ink-out process in S52 and S62 in FIG. 3, S81 and S87 in FIG. 5, S99 in FIG. 6, or S106 in FIG. Is determined as to whether the memory is full (S131). Specifically, the CPU 1 checks whether the free space of the RAM 3 is a predetermined value or more.
[0152]
  If the memory is not full (S131: NO), the CPU 1 stores the received data in the RAM 3 (S133). Specifically, the CPU 1 causes the DMAC 9 to store the received data demodulated by the modem 4 and decoded by the codec 8 in the RAM 3 by a predetermined byte. At this time, since the second threshold value of the dot counter is set with some margin, even if the count value of the dot counter reaches the second threshold value in the middle of the page, the page is printed. Since it is possible, the received data on and after the next page is stored in the RAM 3. Then, the CPU 1 determines whether or not the received data for one page is stored in the RAM 3 (S134).
[0153]
  If reception data for one page is stored in the RAM 3 (S134: YES), the CPU 1 determines whether reception data for all pages is stored in the RAM 3 (S135).
[0154]
  If the reception data of all pages is stored in the RAM 3 (S135: YES), the CPU 1 opens the line (S136). Specifically, the CPU 1 controls the NCU 2 to open the telephone line 21. Then, the CPU 1 controls the display unit 14 to display that black ink has run out in a predetermined area on the display screen of the display unit 14 (S137). Then, the CPU 1 sets a recording prohibition mode (S138) and ends this routine. When the record prohibit mode is set, when facsimile data is received, all of the data is received by proxy, and even if all recorded backup data in the RAM 3 is erased, the free memory capacity does not exceed a predetermined value. Refusal to receive facsimile data. The recording prohibit mode is canceled by cleaning the ink flow path of black ink, which is executed after the user replaces the black ink cartridge.
[0155]
  In S135, if the received data of all pages is not stored in the RAM 3 (S135: NO), that is, if there is received data of the next page to be stored, the process returns to S131 to start preprocessing for storing the next page. To do.
[0156]
  If the received data for one page is not stored in the RAM 3 in S134 (S134: NO), the process returns to S133 and the storage is continued.
[0157]
  If the memory is full in S131 (S131: YES), the CPU 1 determines whether or not the recorded backup data is stored in the RAM 3 (S139). If the recorded backup data is stored in the RAM 3 (S139: YES), the CPU 1 deletes one recorded backup data from the RAM 3, and returns to S131. If the recorded backup data is not stored in the RAM 3 (S139: NO), the backup cannot be performed and the process proceeds to S136.
[0158]
  As described above, when the black ink dot counter reaches the second threshold value, the user is prompted to replace the black ink cartridge, assuming that the black ink has run out.
[0159]
  FIG. 11 is a flowchart for explaining the procedure of the post-cleaning process. This post-cleaning process is performed based on the cleaning of the ink flow path of black ink executed based on a predetermined key operation by the user and the power of the facsimile apparatus is turned on. Cleaning of the black ink ink flow path that is automatically executed at predetermined intervals during the period, or cleaning of the black ink ink flow path that is automatically executed after the user replaces the black ink ink cartridge, Automatically executed after
[0160]
  In the post-cleaning process, first, the CPU 1 determines whether or not the recording prohibit mode is set (S141).
[0161]
  If the recording prohibit mode is set (S141: YES), the CPU 1 cancels the recording prohibit mode (S142). Then, the CPU 1 determines whether or not the mark flag is on (S143). Specifically, the CPU 1 reads a mark flag stored in a predetermined area of the EEPROM 6 and checks whether or not the content is “1”.
[0162]
  If the mark flag is on (S143: YES), the CPU 1 determines whether there is ambient light (S144). Specifically, the CPU 1 monitors the detection output from the mark sensor 15 in a state in which no recording paper exists at the detection position by the mark sensor 15 and the light source such as the light emitting diode of the mark sensor 15 is turned off. Then, it is checked whether or not the detection output exceeds a predetermined value.
[0163]
  If ambient light does not exist (S144: NO), the CPU 1 determines whether or not the count value of the dot counter is equal to or less than a predetermined value (S145).
[0164]
  If the count value of the dot counter is equal to or smaller than the predetermined value (S145: YES), the CPU 1 records the received data backed up in the RAM 3 (S146). Specifically, the CPU 1 reads the backup data stored in the RAM 3 and supplies it to the recording unit 12 via the gate array 7 to print the received image for one band on the recording paper with black ink.
[0165]
  Then, the CPU 1 determines whether or not the recording for one page has been completed (S147).
[0166]
  If the recording for one page has been completed (S147: YES), the CPU 1 controls the recording unit 12 to record the ink empty mark at a predetermined position on the recording paper (S148). Then, the CPU 1 reads the ink empty mark (S149), and determines whether the ink empty mark has been normally read (S150).
[0167]
  The intempty mark must be read correctlyThisIf (S150: NO), the CPU 1 sets the content of the flag B to “1” (S151). Specifically, the CPU 1 reads the flag B from a predetermined area of the EEPROM 6, writes “1” if the content is “0”, and leaves it as it is if it is “1”. This flag B indicates whether or not the ink empty mark has been normally read during the recording of the reception data backed up in the RAM 3, and is stored in a predetermined area of the EEPROM 6. Then, the CPU 1 determines whether or not the recording of the backup data has been completed for all pages for one case (S152).
[0168]
  If the backup data recording has been completed for all pages for one case (S152: YES), the CPU 1 determines whether the recording of backup data has been completed for all cases (S153).
[0169]
  If the recording of the backup data has been completed for all cases (S153: YES), the CPU 1 determines whether or not the content of the flag B is “0” (S154). If the content of the flag B is “0” (S154: YES), it means that the ink empty mark has been read normally over all pages of all cases, and it is considered that the backup data has been recorded normally over all cases. All the received data as backup data stored in the RAM 3 is erased (S155), and this routine is terminated.
[0170]
  In S154, if the content of the flag B is not “0” (S154: NO), the backup data may not be recorded normally. Therefore, the CPU 1 controls the display unit 14 to display on the display unit 14. On the screen, a display for inquiring the user whether or not the recording result is satisfactory is displayed (S156). Specifically, the CPU 1 displays the display as shown in FIG. 15A and the display as shown in FIG. 15B alternately at a predetermined position on the display screen of the display unit 14 every predetermined time. Then, the CPU 1 determines whether or not the user has performed an input operation indicating that the recording is good (S157). Specifically, the CPU 1 monitors an operation signal from the operation unit 13 to check whether the user has pressed the numeric key “1”.
[0171]
  If the input operation indicating that the recording is good is not performed by the user (S157: NO), the CPU 1 determines whether or not the input operation indicating that the recording is bad is performed by the user (S158). Specifically, the CPU 1 monitors an operation signal from the operation unit 13 to check whether or not the user has pressed the “2” numeric keypad.
[0172]
  If the user examines the received image recorded on the recording paper and performs an input operation indicating that the recording is bad (S158: YES), the CPU 1 controls the display unit 14 and the recording result is good. The display for inquiring the user whether or not there is is deleted (S159). Then, the CPU 1 turns off the flag B (S160) and ends this routine.
[0173]
  In S158, if the input operation indicating that the recording is bad is not performed (S158: NO), the process returns to S157 and waits for the input operation by the user.
[0174]
  In S157, if an input operation indicating that the recording is good is performed by the user (S157: YES), the CPU 1 controls the display unit 14 to determine whether the recording result is good or not. The display for inquiring is deleted (S161). Then, the CPU 1 turns off the flag B (S162), and proceeds to S155.
[0175]
  In S153, if the recording of received data is not completed for all cases (S153: NO), that is, if there is received data to be recorded next, the process returns to S144 to record the next backup data. Start pre-processing.
[0176]
  In S152, if the recording of the received data is not completed for all the pages of the case (S152: NO), that is, if there is received data of the next page to be recorded, the process returns to S144 and the backup data of the next page is returned. Start pre-recording.
[0177]
  If the ink empty mark can be read normally in S150 (S150: YES), it is not necessary to set the flag B to “1”, so S151 is skipped and the process proceeds to S152.
[0178]
  If the recording for one page is not completed in S147 (S147: NO), the process returns to S146 and the recording is continued.
[0179]
  In S145, if the count value of the dot counter is not less than or equal to the predetermined value (S145: NO), the CPU 1 displays on the display screen of the recording unit 12 that black ink has run out (S163). Then, the CPU 1 sets a recording prohibit mode (S164). Then, the CPU 1 sets the flag B to “0” (S171) and ends this routine. Specifically, the CPU 1 reads the content of the flag B from a predetermined area of the EEPROM 6 and rewrites it to “0” if the content is “1”, and keeps it as it is if it is “0”.
[0180]
  In S144, if disturbance light has entered (S144: YES), the CPU 1 sets the flag B to “1” (S165). Then, the CPU 1 determines whether or not the count value of the dot counter is equal to or less than a predetermined value (S166).
[0181]
  If the count value of the dot counter is equal to or smaller than the predetermined value (S166: YES), the CPU 1 controls the recording unit 12 to record the backup data (S167). Then, the CPU 1 determines whether or not backup data for one page has been recorded (S168).
[0182]
  If backup data for one page has been recorded (S168: YES), the CPU 1 determines whether backup data for all pages for this case has been recorded (S169).
[0183]
  If all pages of backup data have been recorded (S169: YES), the CPU 1 determines whether all cases of backup data have been recorded (S170).
[0184]
  If all pieces of backup data have been recorded (S170: YES), the process proceeds to S154, and pre-deletion processing is started.
[0185]
  In S170, if all backup data is not recorded (S170: NO), that is, if there is backup data to be recorded next, the process returns to S166 to start preprocessing of the next recording. .
[0186]
  If the backup data for all pages is not recorded in S169 (S169: NO), that is, if there is backup data for the next page to be recorded, the process returns to S166 to start the pre-processing for recording the next page.
[0187]
  In S168, if one page of backup data is not recorded (S168: NO), the process returns to S167 to continue recording the backup data.
[0188]
  In S166, if the count value of the dot counter is not less than the predetermined value (S166: NO), the process proceeds to S163.
[0189]
  In S143, if the mark flag is not on (S143: NO), even if the backup data is automatically recorded, it cannot be determined whether or not the backup data has been normally recorded, so this routine is terminated.
[0190]
  If the recording prohibit mode is not set in S141 (S141: NO), it is not necessary to cancel the recording prohibit mode, so S142 is skipped and the process proceeds to S143.
[0191]
  Thus, if the mark flag is on, the backup data stored in the RAM 3 is automatically recorded after cleaning the ink flow path of black ink, and if all the ink empty marks can be read normally, all Automatically delete the backup data. If there is an ink empty mark that cannot be read normally, the user is inquired whether the backup data can be erased.
[0192]
  FIG. 12 is a flowchart for explaining the procedure of the manual erasure process. This manual erasure process is executed based on a predetermined key operation by the user. For example, when copying in full color printing is performed continuously, the capacity of the RAM 3 is consumed in large quantities for copying. Therefore, if backup data is stored in the RAM 3, copying may not be performed normally. For this reason, the backup data in the RAM 3 can be erased by a key operation on the operation unit 13 by the user. This manual erasure process can be used not only for color copying but also when the user wants to record backup data on a recording sheet.
[0193]
  In the manual erasure process, first, the CPU 1 determines whether backup data is stored in the RAM 3 (S181). This backup data includes not only received data backed up according to the combination of the mark flag, backup flag, and presence / absence of ambient light, but also received data that was intercepted by the memory due to other reasons, such as the absence of recording paper. And received data stored in the RAM 3 for transfer.
[0194]
  If the backup data is stored (S181: YES), the CPU 1 controls the display unit 14 to display a display for inquiring the user of the necessity of recording on a predetermined position on the display screen of the display unit 14. (S182). Specifically, the CPU 1 causes the display as shown in FIG. 13A and the display as shown in FIG. 13B to be alternately displayed at predetermined positions on the display screen of the display unit 14 every predetermined time. Then, the CPU 1 determines whether or not a recording unnecessary input operation has been performed by the user (S183). Specifically, the CPU 1 monitors an operation signal from the operation unit 13 to check whether the user has pressed the “2” numeric keypad. The user can know the information of the backup data stored in the RAM 3 by displaying or recording the memory status list by a predetermined key operation on the operation unit 13, and recording can be performed based on this information. Judgment is necessary. This information includes, for example, the name and telephone number of the transmission source and the date and time of reception. Further, the user can also obtain the backup data information stored in the RAM 3 by a predetermined key operation on the operation unit 13 or a communication management report as shown in FIG. 18 output every predetermined time. I can know. This communication management report is recorded on a recording sheet.
[0195]
  If an input operation that does not require recording is performed by the user (S183: NO), the CPU 1 determines whether or not an input operation that requires recording is performed by the user (S184). Specifically, the CPU 1 monitors an operation signal from the operation unit 13 to check whether the user has pressed the numeric key “1”.
[0196]
  If an input operation requiring recording is performed by the user (S184: YES), the CPU 1 controls the display unit 14 to display that printing is in progress on the display screen of the display unit 14 (S185). Specifically, a display as shown in FIG. 14 is displayed on the display screen of the display unit 14. Then, the CPU 1 determines whether or not the mark flag is on (S186).
[0197]
  If the mark flag is on (S186: YES), the CPU 1 determines the presence or absence of ambient light (S187). Specifically, the CPU 1 monitors the detection output from the mark sensor 15 in a state in which no recording paper exists at the detection position by the mark sensor 15 and the light source such as the light emitting diode of the mark sensor 15 is turned off. Then, it is checked whether or not the detection output exceeds a predetermined value.
[0198]
  If ambient light does not exist (S187: NO), the CPU 1 determines whether or not the count value of the dot counter is equal to or less than a predetermined value (S188).
[0199]
  If the count value of the dot counter is equal to or smaller than the predetermined value (S188: YES), the CPU 1 controls the recording unit 12 to record the backup data stored in the RAM 3 (S189). Specifically, the CPU 1 reads the backup data stored in the RAM 3 and supplies it to the recording unit 12 via the gate array 7 to print the received image for one band on the recording paper with black ink.
[0200]
  Then, the CPU 1 determines whether or not the recording for one page has been completed (S190).
[0201]
  If the recording for one page is completed (S190: YES), the CPU 1 controls the recording unit 12 to record the ink empty mark at a predetermined position on the recording paper (S191).

[0202]
  If the incremental mark cannot be read normally (S193: NO), the CPU 1 sets the content of the flag C to “1” (S194). Specifically, the CPU 1 reads the flag C from a predetermined area of the EEPROM 6, writes “1” if the content is “0”, and leaves it as it is if it is “1”. This flag C indicates whether or not the ink empty mark has been normally read during the recording of the backup data stored in the RAM 3, and is stored in a predetermined area of the EEPROM 6. Then, the CPU 1 determines whether or not the recording of the backup data has been completed for all pages for one case (S195).
[0203]

[0204]
  If the recording of the backup data has been completed for all cases (S196: YES), the CPU 1 determines whether or not the content of the flag C is “0” (S197). If the content of the flag C is “0” (S197: YES), it means that the ink empty mark has been normally read on all pages of all cases, and it is considered that the backup data has been normally recorded on all cases. All the received data as backup data stored in the RAM 3 is erased (S198). Then, the CPU 1 controls the display unit 14 to delete the display on the display screen of the display unit 14 indicating that printing is in progress, or the display for inquiring the user whether or not the deletion is possible (S199). . Then, the CPU 1 sets the flag C to “0” (S200) and ends this routine. Specifically, the CPU 1 reads the content of the flag C from a predetermined area of the EEPROM 6 and rewrites it to “0” if the content is “1”, and keeps it as it is if it is “0”.
[0205]
  In S197, if the content of the flag C is not “0” (S197: NO), the backup data may not be recorded normally. Therefore, the CPU 1 controls the display unit 14 to display on the display unit 14. On the screen, a display for inquiring the user whether or not the recording result is satisfactory is displayed (S201). Specifically, the CPU 1 displays the display as shown in FIG. 15A and the display as shown in FIG. 15B alternately at a predetermined position on the display screen of the display unit 14 every predetermined time. Then, the CPU 1 determines whether or not the user has performed an input operation indicating that the recording is good (S202). Specifically, the CPU 1 monitors an operation signal from the operation unit 13 to check whether the user has pressed the numeric key “1”.
[0206]
  If the input operation indicating that the recording is good is not performed by the user (S202: NO), the CPU 1 determines whether or not the input operation indicating that the recording is bad is performed by the user (S203). Specifically, the CPU 1 monitors an operation signal from the operation unit 13 to check whether or not the user has pressed the “2” numeric keypad.
[0207]
  If the user checks the received image recorded on the recording paper and performs an input operation indicating that the recording is defective (S203: YES), the process proceeds to S199.
[0208]
  In S203, if an input operation indicating that the recording is bad is not performed (S203: NO), the process returns to S202 and waits for an input operation by the user.
[0209]
  In S202, if an input operation indicating that the recording is good is performed by the user (S202: YES), the process proceeds to S198.
[0210]
  In S196, if recording of received data has not been completed for all cases (S196: NO), that is, if there is received data to be recorded next, the process returns to S187 to record the next backup data. Start pre-processing.
[0211]
  In S195, if recording of the received data has not been completed for all the pages of the case (S195: NO), that is, if there is received data for the next page to be recorded, the process returns to S187 and the backup data of the next page Start pre-recording.
[0212]
  If the ink empty mark can be read normally in S193 (S193: YES), it is not necessary to set the flag C to “1”, so S194 is skipped and the process proceeds to S195.

[0220]
  If all backup data is not recorded in S211 (S211: NO), that is, if there is backup data to be recorded next, the process returns to S207 to start preprocessing of the next recording. .
[0221]
  In S210, if the backup data for all pages is not recorded (S210: NO), that is, if there is backup data for the next page to be recorded, the process returns to S207 and preprocessing for recording the next page is started.

[0225]
  In S184, if there is no operation input indicating that recording is necessary (S184: NO), the process returns to S183 and waits for an operation input by the user.
[0226]
  In S183, if there is an operation input indicating that recording is unnecessary (S183: YES), the CPU 1 controls the display unit 14 to inquire whether the user can delete the backup data. The display is displayed on the display screen of the display unit 14 (S212). Specifically, the CPU 1 causes the display as shown in FIG. 16A and the display as shown in FIG. 16B to be alternately displayed at predetermined positions on the display screen of the display unit 14 every predetermined time. Then, the CPU 1 determines whether or not the user has performed an input operation indicating that the backup data may be deleted (S213). Specifically, the CPU 1 monitors an operation signal from the operation unit 13 to check whether the user has pressed the numeric key “1”.
[0227]
  If the user has not performed an input operation indicating that the backup data may be deleted (S213: NO), the CPU 1 determines whether or not the user has performed an input operation indicating that the backup data should not be deleted. Judgment is made (S214). Specifically, the CPU 1 monitors an operation signal from the operation unit 13 to check whether or not the user has pressed the “2” numeric keypad.
