[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a telephone device, and in particular, switches a setting for receiving information such as a telephone number of a calling side device to an active state or a stopped state based on a signal sent from the exchange before closing the line. It is related with the telephone apparatus which can do.
[0002]
[Prior art]
  In Japan, the United States, and the United Kingdom, so-called outgoing telephone number display services ("number display", "Caller ID") have been put into practical use. This service is a service for transmitting the telephone number (caller number) of the calling device (caller) from the exchange to the called device (phone device) when the called device subscribes to the service. It is. The timing for transmitting the caller ID is a silent period immediately before the call signal in Japan and the United Kingdom, and a silent period between the first call signal and the next call signal in the United States. Thus, the calling party number is received by the called device before the receiver picks up the receiver of the called device (while the receiver is on hook). Therefore, if this service is used, the caller number is displayed on the display of the called device (for example, a liquid crystal display (LCD)) before picking up the receiver of the called device, and the caller is notified to the receiver. Can be recognized.
[0003]
  If the calling telephone number display service is subscribed, the caller number is transmitted from the exchange to the called side device, so the signal transmitted and received between the exchange and the called side device before the call is This is different from the case of not subscribing to the outgoing telephone number display service. Therefore, in order to subscribe to the calling phone number display service and display the calling party number on the LCD of the called party device, a telephone device corresponding to the calling phone number display service is prepared and provided in the telephone device. It is necessary to set the function for receiving a caller ID to ON. In other words, if the telephone device is subscribed to the calling telephone number display service, the function for enabling the reception of the caller ID sent from the exchange to the called device is turned on, and conversely When the calling telephone number display service is not subscribed, it is set to the off state.
[0004]
[Problems to be solved by the invention]
  However, even if the caller telephone number display service is subscribed, the user may forget to set the function for receiving the caller number sent from the exchange to the called device to the on state. In addition, for those who are not good at operating machines and devices, it is difficult to know how to set such a function to the on state, and complicated operations are forced. Even if you subscribe to the calling phone number display service, if you do not set the function to receive the caller ID to the on state and set it to the off state, the caller sent from the exchange to the called device There was a problem that the number could not be received.

DETAILED DESCRIPTION OF THE INVENTION
  Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. First, referring to FIG. 6, when a call is made, it is transmitted / received between the called side device subscribed to the calling telephone number display service (“number display”, “Caller ID”) and the exchange. Various signals will be described.
[0018]
  As shown in FIG. 6, first, when a call is made from a calling side device (not shown) to the called side device 51, the exchange 50 connects the called side device 51 and the exchange 50 in order to transmit and receive various signals. The polarity reversal 41 of the telephone line is performed. The polarity of the telephone line is normally made negative on the L1 side of the telephone line and positive on the L2 side by a DC power supply (battery) (not shown) provided on the exchange 50 side. Therefore, when the polarity inversion 41 of the telephone line is performed, the L1 side of the telephone line is inverted to plus and the L2 side is inverted to minus.
[0019]
  When the switch 50 performs the polarity reversal 41 of the telephone line, it transmits an information receiving terminal activation signal 42 indicating that the caller number (the telephone number of the calling side device) is notified to the called side device 51. The called device 51 recognizes that the caller number is notified from the exchange 50 by receiving the information receiving terminal activation signal 42. When the information receiving terminal activation signal 42 is received, a primary response signal 43 indicating that the caller ID can be received from the called side device 51 is transmitted to the exchange 50. The primary response signal 43 is transmitted when the called device 51 closes the telephone line. The exchange 50 receives the primary response signal 43 when the resistance value of the telephone line (including the resistance value of the DC (internal) circuit of the called device 51) measured from the exchange 50 side becomes 50Ω or more and 1700Ω or less. to decide.
[0020]
  When receiving the primary response signal 43, the exchange 50 receives the ITU-T recommendation V.30. A MODEM signal 44 compliant with the standard 23 is transmitted to the called device 51. The caller number is transmitted to the called device 51 by this MODEM signal 44. When the called device 51 receives the MODEM signal 44, the called device 51 transmits a reception completion signal 45 indicating that the caller number is received by the MODEM signal 44 to the switch 50. The reception completion signal 45 is transmitted by opening the telephone line, and the exchange 50 determines that the reception completion signal 45 has been received when the resistance value of the telephone line measured from the exchange 50 side becomes 1 MΩ or more.
[0021]
  When receiving the reception completion signal 45, the exchange 50 transmits a calling signal 46 indicating that there is an incoming call from the calling side device to the called side device 51 to the called side device 51. When the receiver is picked up by the receiver and enters the on-hook state, the called device 51 transmits a secondary call signal 47 indicating that the incoming call has been answered to the exchange 50 by closing the telephone line. . Similarly to the case of the primary response signal 43 described above, the exchange 50 has a telephone line resistance value (including the resistance value of the DC circuit of the called device 51) measured from the exchange 50 side of 50Ω to 1700Ω. It is determined that the secondary response signal 47 has been received.
[0022]
  When the exchange 50 receives the secondary response signal 47, it performs the polarity reversal 48 of the telephone line. That is, this polarity reversion returns the L1 side to minus and the L2 side to plus. After the polarity is reversed, a call 49 is made between the caller (caller of the calling device) and the receiver (caller of the called device 51) via the telephone line and the exchange 50.
[0023]
  Next, various signals transmitted and received between the exchange 50 and the called device 51 when the called device 51 has not subscribed to the calling telephone number display service will be described. When the called side device 51 does not subscribe to the calling telephone number display service, signals 41 and 46 to 48 except for the parentheses in FIG. 6 are transmitted and received between the called side device 51 and the exchange 50. Is done.
[0024]
  The exchange 50 first reverses the polarity 41 of the telephone line connecting the exchange 50 and the called device 51, and inverts the L1 side to plus and the L2 side to minus. When switching the polarity, the exchange 50 transmits a call signal 46 to the called device 51. When the called device 51 receives the call signal 46, it transmits a secondary response signal 47 to the exchange 50. As described above, the secondary response signal 47 is transmitted by closing the telephone line when the receiver goes off-hook by the receiver. When the exchange 50 receives the secondary response signal 47, it performs the polarity depolarization 48 of the telephone line, and depolarizes the L1 side to negative and the L2 side to positive. After the repolarization of the polarity, a call 49 is performed between the caller and the receiver via the telephone line and the exchange 50.
[0025]
  As described above, transmission / reception is performed between the exchange 50 and the called-side device 51 at the time of a call when the caller telephone number display service is subscribed and when the caller telephone number display service is not subscribed. The signal is different. Therefore, in order to subscribe to the calling telephone number display service and display the calling party number on the LCD of the called side device 51, a telephone apparatus corresponding to the calling telephone number display service is prepared and provided in the telephone apparatus. It is necessary to set the function (number display function) for receiving the caller ID being turned on.
[0026]
  It should be noted that the caller number is not always sent from the exchange 50 as long as it is subscribed to the calling telephone number display service. Specifically, when the calling side device refuses to notify the telephone number, the caller number is not transmitted from the exchange 50 to the called side device 51. However, even in this case, information indicating that the caller ID cannot be transmitted is transmitted to the called device 51 by the MODEM signal 44.
[0027]
  The facsimile apparatus 1 according to the present embodiment receives the information receiving terminal activation signal 42 using this calling telephone number display service, thereby setting the number display function to the on state, and as a result, receiving the caller number. I am doing so. In this embodiment, the exchange 50 in FIG. 6 will be described as the exchange 29, and the called apparatus 51 will be described as the facsimile apparatus 1.
[0028]
  FIG. 1 is an external perspective view of a facsimile machine 1 according to an embodiment of the present invention. As shown in FIG. 1, a handset 3 is attached to the side of the main body 2 of the facsimile machine 1. The handset 3 is placed on a hook (not shown) provided in the main body 2 when not talking, and is picked up from the hook and used when talking. The former is called an on-hook state, and the latter is called an off-hook state.
[0029]
  An operation panel 4 having a plurality of buttons 4a is provided at the front upper portion of the main body 2, and a liquid crystal display (LCD) 5 for displaying a caller number is provided at the left rear portion of the operation panel 4. ing. The facsimile apparatus 1 is operated by pressing each button 4 a provided on the operation panel 4, and its operation state and operation procedure are displayed on the LCD 5.
[0030]
  A document insertion slot 6 is provided at the rear of the operation panel 4 and the LCD 5. A document to be transmitted by facsimile is inserted into the document insertion opening 6 with the document surface facing downward, and after being read, is read from a document discharge opening 7 provided on the front surface of the main body 2 and below the operation panel 4. Discharged. A recording paper holder mounting portion 9 is provided at the rear portion of the document insertion opening 6, and a recording paper holder 10 capable of stacking and storing a plurality of recording papers is detachably attached to the recording paper holder mounting portion 9. ing. 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.
[0031]
  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, and the amplifier 27 are provided, and these are connected to each other via a bus line 30.
[0032]
  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 various signals such as a call signal 46 and a caller number 44 transmitted from the exchange 29, and transmits a dial signal at the time of outgoing call according to the operation of the button 4a provided on the operation panel 4 to the exchange 29. Or further transmits / receives an analog audio signal during a call.
[0033]
  The CPU 11 is for performing facsimile operation, telephone operation, that is, data communication by controlling each unit connected by the bus line 30 according to various signals transmitted / received via the NCU 19. The ROM 12 is a non-rewritable memory storing a control program executed by the facsimile apparatus 1, and the programs shown in the flowcharts of FIGS. 3 to 5 are stored in the ROM 12.
[0034]
  The EEPROM 13 is a rewritable nonvolatile memory, and the data stored in the EEPROM 13 is retained even after the power of the facsimile apparatus 1 is turned off. The EEPROM 13 includes a number flag 13a. The number flag 13a is a flag for storing the setting state of the number display function for receiving the caller number sent from the exchange 29.
[0035]
  If the first signal sent from the exchange 29 is the information receiving terminal activation signal 42, the facsimile apparatus 1 sets the number display function to the on state and turns on the number flag 13a. On the other hand, if the first signal sent from the exchange 29 is not the information receiving terminal activation signal 42 but the call signal 46, the function is set to the off state and the number flag 13a is turned off. As described above, when the calling telephone number display service is subscribed, the first signal sent from the exchange 29 to the facsimile apparatus 1 is the information receiving terminal activation signal 42, whereas the calling telephone number display service is subscribed. If not, the call signal 46 is the first signal sent from the exchange 29 to the facsimile machine 1.
[0036]
  The RAM 14 is a memory for temporarily storing various data when each operation of the facsimile apparatus 1 is executed, and includes a state storage flag 14a. The state storage flag 14a is a flag for saving the contents of the number flag 13a when the information receiving terminal activation signal 42 sent from the exchange 29 is received.
[0037]
  Here, the information receiving terminal activation signal 42 and the extension call signal (extension signal) are approximate. Specifically, the information receiving terminal activation signal 42 is a signal that repeats on for 0.5 s (seconds) and off for 0.5 s, whereas the extension signal is on for 0.5 s and 2 s. Is a signal that repeatedly turns off. Therefore, when the facsimile apparatus 1 is used in an environment where extension lines and external lines coexist, the facsimile apparatus 1 may mistakenly recognize the extension signal as the information reception terminal activation signal 42.
[0038]
  If the extension signal is mistaken for the information receiving terminal activation signal 42, the number display function is set to the ON state together with the number flag 13a even though the information receiving terminal activation signal 42 is not received. Therefore, in such a case, the number flag 13a and the setting of the number display function must be returned to the original state, and the original state is stored (saved) in the state storage flag 14a.
[0039]
  The outside line calling signal 46 is a signal that repeatedly turns on 1s and off 2s, so that the outside line calling signal 46 is not mistakenly recognized as the information receiving terminal activation signal 42.
[0040]
  The image memory 15 is a memory for storing a communication history, image data, and a bit image for printing, and is configured by 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 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
[0041]
  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).
[0042]
  The modem 20 modulates and demodulates image information and transmits / receives various procedure signals for transmission control. The buffer 21 is encoded and transmitted / received to / from the 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 the received image data stored in the buffer 21 or the image memory 15 and decodes it. The decoded data is printed on a recording sheet by the printer 25.
[0043]
  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. And for outputting sound.
[0044]
  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.
[0045]
  Next, the operation of the facsimile apparatus 1 configured as described above will be described with reference to the flowcharts of FIGS. FIG. 3 is a flowchart showing processing at the time of an incoming call.
[0046]
  As shown in FIG. 3, the facsimile apparatus 1 waits for an incoming call (S1: No). When an incoming call is received (S1: Yes), the contents of the number flag 13a storing the setting of the number display function are confirmed. (S2). If the number flag 13a is off (S2: OFF), it is determined whether or not the incoming signal in the processing of S1 is the information receiving terminal activation signal 42 (S3). If the received signal is not the information receiving terminal activation signal 42 as a result of the determination (S3: No), the telephone process shown in FIG. 4 is executed (S12).
[0047]
  On the other hand, if the incoming signal is the information reception terminal activation signal 42 (S3: Yes), the state storage flag 14a is turned off (S4) in order to store (save) the contents of the number flag 13a. After the state storage flag 14a is turned off, the number flag 13a is turned on and the device for operating the number display function is set in response to the arrival of the information receiving terminal activation signal 42 (S5). After the setting, the telephone line is closed to transmit the primary response signal 43 to the exchange 29 (S6).
[0048]
  Thus, even when the number flag 13a is off and the setting for operating the number display function is not performed, if the first incoming signal is the information receiving terminal activation signal 42, the number display function is activated. Settings for operation are made. Therefore, the recipient who newly subscribes to the calling telephone number display service can set the number display function to the operating state without being forced to perform complicated setting operations such as the button 4a operation.
[0049]
  In the process of S2, if the number flag 13a is on (S2: ON), it is determined whether or not the signal received in the process of S1 is the information receiving terminal activation signal 42 (S7). If the received signal is the information reception terminal activation signal 42 as a result of the determination (S7: Yes), the state storage flag 14a is turned on (S8) in order to store (save) the contents of the number flag 13a. After the state storage flag is turned on, the telephone line is closed to transmit the primary response signal 43 to the exchange 29 (S6).
[0050]
  After the telephone line is closed (S6), it is determined whether the caller number is received from the exchange 29 (S9). As described above, since the extension signal and the information reception terminal activation signal 42 are approximate, it is considered that the extension signal is mistakenly recognized as the information reception terminal activation signal 42 in the processes of S3 and S7. If the caller ID is received from the exchange 29 as a result of the determination (S9: Yes), the signal recognized in the processing of S3 and S7 is the information receiving terminal activation signal 42, and therefore the reception completion signal 45 is sent to the exchange 29. The telephone line is released for transmission (S10).
[0051]
  After the telephone line is released, the caller number is displayed on the LCD 5 (S11). By looking at the display on the LCD 5, the receiver can recognize the caller before picking up the receiver 3. After the display on the LCD 5, the telephone process shown in FIG. 4 is executed (S12).
[0052]
  If the received signal is not the information receiving terminal activation signal 42 in the process of S7 (S7: No), it is confirmed whether or not the received signal is an extension signal (S13). If the incoming signal is an extension signal (S13: Yes), the telephone processing shown in FIG. 4 is executed without changing the setting of the number display function operation or stop state (S12). On the other hand, when the incoming signal is not the extension signal, that is, the outside line calling signal 46 (S13: No), the number flag 13a is turned off and the apparatus for stopping the number display function is set. (S14). After the setting, the telephone process shown in FIG. 4 is executed (S12).
[0053]
  As described above, even when the number flag 13a is on and the number display function is in the operating state, if the first incoming signal is the ringing signal 46, the setting for stopping the number display function is performed. Therefore, even if the recipient who has subscribed to the outgoing telephone number display service is not subscribed to the service, the number display function is set to the stopped state without being forced to perform complicated setting operations such as the button 4a operation. It can be done.
[0054]
  In the telephone process shown in FIG. 4, first, it is confirmed whether or not the calling signal 46 or the extension signal continues (S20). If the signal continues (S20: Yes), the speaker is sounded to notify the receiver that there was an incoming call (S21). After the speaker rings, it is checked whether the handset 3 has been picked up, that is, whether it is in an off-hook state (S22). If the handset 3 is not picked up yet and is in an on-hook state (S22: No), the process proceeds to S20, and the process from S20 to S22 is repeated while the signal continues (S20: Yes). If the signal is interrupted in the meantime (S20: No), this telephone process is terminated.
[0055]
  On the other hand, if the handset 3 is picked up and enters an off-hook state (S22: Yes), the telephone line is closed to transmit the secondary response signal 47 to the exchange 29 (S23). After the telephone line is closed, call processing is executed (S24). The call process (S24) is continued while the handset 3 is in the off-hook state (S25: No). If the handset 3 is lowered and enters the on-hook state (S25: Yes), the telephone line is released (S26), and this telephone process is terminated. After the telephone process (S12) ends, the process proceeds to S1 in FIG. 3 and waits for the next incoming call (S1).
[0056]
  If the caller ID is not received from the exchange 29 in S9 (S9: No), the extension signal is mistakenly recognized as the information receiving terminal activation signal 42 in S3 and S7. Therefore, the malfunction process shown in FIG. 5 is executed (S15).
[0057]
  The malfunction processing of FIG. 5 is processing when an extension signal is mistakenly recognized as the information receiving terminal activation signal 42. In such a case, since the telephone processing (S12) cannot be performed, as shown in FIG. 5, first, a message “Please retry” is output to the calling side device which is the extension destination (refer to FIG. 5). S30). Thereby, it is possible to request the caller of the calling side apparatus, which is the destination of the extension signal, to re-call.
[0058]
  After the message is output, the telephone line is released (S31), and the contents of the state storage flag 14a are confirmed (S32). If the state storage flag 14a is off (S32: OFF), the incoming extension signal is mistakenly recognized as the information receiving terminal activation signal 42 from the exchange 29, and the number flag 13a is switched from off to on. Then, the number flag 13a is turned off and the apparatus is set to stop the number display function (S33). After the setting, this malfunction process is terminated. On the other hand, if the state storage flag 14a is on (S32: ON), the contents of the number flag 13a are not changed, so the process of S32 is skipped as it is, and this malfunctioning process is terminated. After the malfunction process is completed, the process proceeds to S1 in FIG. 3 to wait for the next incoming call (S1).
[0059]
  Thus, even if the extension state signal is mistakenly recognized as the information receiving terminal activation signal 42 and the setting state of the number display function is erroneously switched to the operating state, the function of the function is determined based on the state storage flag 14a. The setting state can be returned to the original state.
[0060]
  In this embodiment, from claim 14The operation state setting means described in the above corresponds to the processes of S5, S14 and S33, and the detection means corresponds to the processes of S3 and S7.Also,The first switching means corresponds to the process of S5.SizeThe determination means corresponds to the process of S9. Claim1,3as well as4The process of S33 corresponds to the third switching means described in. Claim2From4The fourth switching unit described in (3) corresponds to the process of S33. Claim3Or4Message notification described inmeansThis corresponds to the process of S30.
[0061]

【The invention's effect】
  According to the telephone device of the first aspect, when a signal indicating notification of the information on the calling side device is detected from the signal received by the signal receiving unit, the first switching unit makes a call by the operation state setting unit. The setting of the call side information receiving means is switched to the operating state. Thereby, the information on the calling side device sent from the exchange side is set to be receivable by the calling side information receiving means. Therefore, since the setting of the calling side information receiving means is automatically switched to the operating state based on the signal sent from the switch side before the line is closed, the switch side is not forced to perform a troublesome switching operation. There is an effect that it is possible to reliably receive the information of the calling side device to be sent.
  Further, if the detection means determines that the signal indicating that the information on the calling side device is to be notified by the detection means is not appropriate and that the signal indicates another information is detected, the first switching means switches once. The setting of the calling side information receiving means by the operating state setting means is switched to the original state by the third switching means. Therefore, even if a signal indicating different information is mistakenly detected as a signal indicating notification of information on the calling side device, the setting of the calling side information receiving means can be switched to the original state, which is unnecessary. Thus, it is possible to prevent the problem that the setting state of the calling side information receiving means is switched.

  Claim2According to the telephone device described,When a signal indicating notification of information on the calling side device is detected from the signal received by the signal receiving means, the setting of the calling side information receiving means by the operation state setting means is set to the operating state by the first switching means. Can be switched. Thereby, the information on the calling side device sent from the exchange side is set to be receivable by the calling side information receiving means. Therefore, since the setting of the calling side information receiving means is automatically switched to the operating state based on the signal sent from the switch side before the line is closed, the switch side is not forced to perform a troublesome switching operation. There is an effect that it is possible to reliably receive the information of the calling side device to be sent.
  Furthermore,When it is determined by the determination means that the detection of the signal indicating that the information on the calling side device is notified by the detection means is not appropriate and the detection of the signal indicating other information,Once switched by the first switching meansThe caller information receiving means is set by the operating state setting means.By the fourth switching meansSwitch to the stopped state. Therefore, even if a signal indicating different information is detected by mistake with a signal indicating notification of the information on the calling side device, the setting of the calling side information receiving means can be switched to the stopped state, and the call is erroneously made. It is possible to prevent the problem that the setting state of the call side information receiving means is switched.
[0071]
  Claim3According to the described telephone device, the claim1Or2In addition to the effect achieved by the telephone apparatus described in (2), the determination means determines that the signal indicating that the information on the calling side apparatus is notified by the detecting means is not appropriate and that the signal indicates another information is detected. Then, a predetermined message is notified by the message notification means to the calling side device which is the transmission destination of the signal indicating the other information. Therefore, by using, for example, a message requesting that the call be called again as a predetermined message, it is possible to request a re-call to the caller of the calling side device that is the signal destination. There is an effect.
[0072]
  Claim4According to the described telephone device, the claim1From3In addition to the effect of the telephone apparatus described in any of the above, since the signal indicating the other information is an extension call signal, the telephone apparatus should be used even in an environment where internal and external lines are mixed. There is an effect that can be.
