The recording paper supplied from the recording paper holder 10 and used for printing is discharged from a recording paper discharge port 8 provided below the document discharge port 7.
[0020]
FIG. 2 is a block diagram showing an electrical configuration of the facsimile apparatus 1. The facsimile apparatus 1 includes a CPU 11, ROM 12, EEPROM 13, RAM 14, image memory 15, audio memory 16, audio LSI 17, network control unit (hereinafter referred to as “NCU”) 19, modem 20, buffer 21, scanner 22, code The control unit 23, the decryption unit 24, the printer 25, the operation panel 4, the amplifier 27, and the clock circuit 33 are provided and are connected to each other via the bus line 30.
[0021]
The NCU 19 is used for line control, and the facsimile apparatus 1 is connected to the telephone line 31 via the NCU 19. The NCU 19 receives a call signal or a caller number transmitted from the exchange 29, and transmits a dial signal at the time of outgoing call according to the operation of the key 4a provided on the operation panel 4 to the exchange 29. Transmits and receives analog audio signals during a call.
[0022]
The CPU 11 controls each unit connected by the bus line 30 according to various signals transmitted / received via the NCU 19 to execute a facsimile operation or a telephone operation, that is, data communication. The clock circuit 33 is for counting time, and the time counted by the clock circuit 33 is read by the CPU 11 and used for each processing. The ROM 12 is a non-rewritable memory storing a control program executed by the facsimile apparatus 1, and each program shown in the flowcharts of FIGS. 3 and 4 is stored in the ROM 12.
[0023]
The EEPROM 13 is a rewritable nonvolatile memory, and data stored in the EEPROM 13 is retained even after the facsimile apparatus 1 is powered off. The EEPROM 13 includes a timer counter 13a for storing a display time for displaying the caller number on the LCD 5. The facsimile apparatus 1 displays the caller number on the LCD 5 for the display time corresponding to the value stored in the timer counter 13a, and then deletes the display of the caller number. Therefore, the display of the caller number can be erased from the LCD 5 without causing the receiver to operate the key 4a on the operation panel 4 as the display time elapses.
[0024]
The RAM 14 is a memory for temporarily storing various data when each operation of the facsimile apparatus 1 is executed, and includes a caller number memory 14a and a display flag 14b.
[0025]
When there is a new incoming call during a call with one counterpart device (while the telephone line is closed), the caller number memory 14a is the "call waiting caller ID service" described in the prior art section. "Is a memory for temporarily storing the caller number transmitted from the exchange 29. Therefore, if the caller number is not transmitted from the exchange 29 even if a new incoming call is received during a call, the content of the caller number memory 14a is cleared to “0”. Accordingly, the contents of the caller number memory 14a are examined, and if it is not "0", it can be determined that the telephone number stored in the caller number memory 14a is an incoming call from the other party device (caller). If the content of the caller number memory 14 a is “0”, it can be determined that the telephone number of the partner apparatus (caller) that has newly received a call during a call has not been transmitted from the exchange 29.
[0026]
The display flag 14b is a flag for storing whether or not the display key 4d has been pressed by the receiver. The initial value of the flag 14b is set to off, and when the display key 4d is pressed, the display flag 14b is set to on. If the display flag 14b is on, the facsimile apparatus 1 determines that the display key 4d has been pressed. Therefore, in such a case, even if the display time for the value of the timer counter 13a has elapsed, the display of the caller ID is not erased.
[0027]
The image memory 15 is a memory for storing a communication history, image data, and a bit image for printing, and is composed of a dynamic RAM (DRAM) that is an inexpensive large-capacity memory. The received image data is temporarily stored in the image memory 15, printed on recording paper by the printer 25, and then erased from the image memory 15. In general, the image data has a large capacity, but since the image data is erased on condition that the image data is printed, the image memory 15 can be used effectively. The voice memory 16 is a memory for storing a message notified to the receiver, a response message sent to the calling side device, and an incoming message sent from the calling side device. Like the image memory 15, it is composed of a dynamic RAM (DRAM) which is an inexpensive large-capacity memory. The incoming message stored in the voice memory 16 is erased by performing a erasure operation via the operation panel 4 or by receiving a erasure command sent from another device connected to the telephone line. The
[0028]
The voice LSI 17 performs voice recognition processing for converting an analog voice signal received by the NCU 19 into a digital voice signal, converts a digital voice signal generated inside the facsimile apparatus 1 into an analog voice signal, and converts the digital voice signal into an NCU 19 or a speaker. This is for performing a speech synthesis process to be output to 28 (amplifier 27).
[0029]
A modem 20 modulates and demodulates image information and transmits / receives various procedure signals for transmission control, and a buffer 21 is encoded and transmitted / received to / from a counterpart facsimile machine. This is for temporarily storing data including image information. The scanner 22 is for reading an image from a document inserted in the document insertion slot 6, and the encoding unit 23 is for encoding the image read by the scanner 22. The decoding unit 24 reads out received image data stored in the buffer 21 or the image memory 15 and decodes the received image data. The decoded data is printed on a recording sheet by the printer 25.
[0030]
The operation panel 4 is for performing various operations when the receiver performs setting of the facsimile apparatus 1 and the like. The amplifier 27 rings a speaker 28 connected to the amplifier 27 to generate a ringing tone. Or for outputting audio.
[0031]
The facsimile apparatus 1 configured as described above is connected to the telephone line 31 via the NCU 19. The telephone line 31 is connected to the exchange 29 of the facsimile apparatus 1, and the exchange 29 is connected to another exchange via the telephone line 32. The other exchange is further connected to the calling side device via a telephone line.
[0032]
Next, the operation of the facsimile apparatus 1 configured as described above will be described with reference to the flowcharts of FIGS. FIG. 3 shows the call waiting process. As shown in FIG. 3, the facsimile apparatus 1 is waiting for a new incoming call while the telephone line with one partner apparatus is closed (S1: No). If there is a new incoming call and an interrupt tone is sounded from the receiver 3 on the receiver side (S1: Yes), has the caller number transmitted from the exchange 29 been received by the above-mentioned call waiting caller ID service? It is determined whether or not (S2). If the caller number is received as a result of the determination (S2: Yes), the received caller number is written into the caller number memory 14a (S3) and the contents of the caller number memory 14a are displayed on the LCD 5 (S4).
[0033]
On the other hand, even if the facsimile apparatus 1 is subscribed to the call waiting caller ID service, if the caller refuses to send a telephone number, the caller number is not sent from the exchange 29. I can't receive my number. Therefore, in such a case (S2: No), the content of the caller number memory 14a is cleared to “0” (S5), and it is stored that the caller number could not be received.
[0034]
After clearing “0” in the caller number memory 14a (S5) or displaying the caller number on the LCD 5 (S4), it is confirmed whether or not the interrupt sound continues (S6). If the interruption sound does not continue (S6: No), the incoming call of a new telephone is interrupted, so the process proceeds to S11 and the display of the contents of the caller number memory 14a is erased from the LCD 5 (S11). This call waiting process is terminated.
[0035]
On the other hand, if the interruption sound continues (S6: Yes), it is determined whether or not the switching key 4b is pressed by the receiver (S7). If the switch key 4b is not pressed as a result of the determination (S7: No), the process proceeds to S6, and the processes of S6 and S7 are repeated. If the switch key 4b is pressed during that time (S7: Yes), the other party of the call is switched to the other party of the incoming call (S8). After switching, the caller ID display non-display setting process shown in FIG. 4 is executed (S9).
[0036]
In addition, since the interruption sound of S6 (SAS signal) is transmitted from the exchange 29 about every 4 s in Japan and the like, the call from the newly called caller continues due to the continuous state of the interruption sound. I confirmed whether or not. However, in the United States and the like, such interruption sound (SAS signal) is transmitted only twice with an interval of about 10 s. Therefore, in the United States where the interruption sound is transmitted only twice, the process of S6 in the flowchart of FIG. 3, that is, the determination process of whether or not the interruption sound is continued is deleted, and the call waiting process is configured. You may make it do.
[0037]
The caller number display non-display setting process of FIG. 4 is a process for displaying the caller number on the LCD 5 or setting for hiding. As shown in FIG. 4, first, the time of the clock circuit 33 is read, and the time counting for the value stored in the timer counter 13a is started (S21). After the start of timing, the display flag 14b is turned off to initialize the display flag 14b for storing whether or not the display key 4d is pressed by the receiver (S22). After the display flag 14b is turned off, the contents of the display flag 14b are confirmed (S23). If the display flag 14b is off (S23: OFF), since the display key 4d has not been pressed by the receiver yet, the time of the clock circuit 33 is monitored and the time of the clock circuit 33 read in the process of S21 is used. It is determined whether or not the time corresponding to the value stored in the timer counter 13a has elapsed (S24). As a result of the determination, when the time count for the value stored in the timer counter 13a is completed (S24: Yes), the display of the contents of the caller number memory 14a is erased from the LCD 5 (S25). On the other hand, when the time measurement has not ended (S24: No), the process of S25 is skipped. If the display flag 14b is ON in the process of S23 (S23: ON), the display key 4d is pressed by the receiver, and the processes of S24 and S25 are skipped.
[0038]
Thus, when the time count for the value stored in the timer counter 13a is completed, the caller number displayed on the LCD 5 is deleted. Therefore, the display of the caller number can be erased without causing the receiver to operate the key 4a on the operation panel 4 as the display time elapses.
[0039]
Next, it is confirmed whether or not the display key 4d is pressed by the receiver (S26). If the display key 4d is pressed (S26: Yes), the content of the caller number memory 14a is “0”. It is determined whether or not (S27). As a result of the determination, if the content of the caller number memory 14a is not “0” (S27: No), the caller number sent from the exchange 29 can be received, so the content of the caller number memory 14a. Is displayed on the LCD 5 (S28). After the display, the display flag 14b is turned on to store that the display key 4d has been pressed (S29). On the other hand, when the content of the caller number memory 14a is “0” (S27: Yes), since the caller number could not be received, the processes of S28 and S29 are skipped. If the display key 4d is not pressed in the process of S26 (S26: No), the setting of displaying the contents of the caller number memory 14a on the LCD 5 is not performed, so the processes of S27 to S29 are skipped.
[0040]
Thus, when the display key 4d is pressed by the receiver and the content of the caller number memory 14a is not “0”, the caller number is displayed on the LCD 5. Therefore, even if the display of the caller number is erased from the LCD 5, the recipient can redisplay the caller number on the LCD 5 by pressing the display key 4d when it is necessary to take a note of the caller number. Can do it.
[0041]
Next, it is confirmed whether or not the stop key 4c is pressed by the receiver (S30). If the stop key 4c is pressed (S30: Yes), the display of the content of the caller number memory 14a is erased from the LCD 5. (S31). On the other hand, if the stop key 4c is not pressed (S30: No), the display of the contents of the caller number memory 14a is not set to be erased from the LCD 5, and the process of S31 is skipped.
[0042]
As described above, when the stop key 4c is pressed by the receiver, the caller number displayed on the LCD 5 is deleted. Therefore, when it is no longer necessary for the receiver to display the caller number on the LCD 5, the receiver number can be immediately erased by pressing the stop key 4c.
[0043]
Next, it is confirmed whether or not the switching key 4b is pressed by the receiver (S32). If the switching key 4b is not pressed (S32: No), the process proceeds to S23, and the processes from S23 to S32 are performed. repeat. If the switching key 4b is pressed (S32: Yes), the caller ID display non-display setting process is terminated.
[0044]
After the caller number display non-display setting process (S9) is completed, the process proceeds to S10 in FIG. 3, and the other party is switched to the telephone party that was calling first (S10). After switching, the caller ID display is erased from the LCD 5 (S11), and this call waiting process is terminated.
[0045]
In this way, when the connected telephone line is switched from the newly received telephone to the telephone that was previously calling, the caller ID display is erased from the LCD 5. Therefore, the caller ID display can be erased in accordance with the switching of the telephone line.
[0046]
In this embodiment, as the erasing means according to claims 1 to 6,S11 orS25ofProcessing is applicable. Claim16 to 6 correspond to the processing of S21 and S24. The re-display means according to claim 6 corresponds to the processing of S28.
[0047]
The present invention has been described based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various improvements and modifications can be easily made without departing from the spirit of the present invention. It can be guessed.
[0048]
For example, in the facsimile apparatus 1 of the present embodiment, the content of the caller number memory 14a, that is, the telephone number of the partner apparatus is displayed on the LCD 5 in the process of S4. However, instead of this, the name of the counterpart device is stored in advance in association with the telephone number of the counterpart device, and in the process of S4, the stored name of the counterpart device is used as the caller number. Instead of the contents of the memory 14a, it may be configured to display on the LCD 5.
[0049]
