2. Description of the Related Art In Japan, the United States and the United Kingdom, so-called outgoing telephone number display services ("number display", "Caller ID") have been put to 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 (telephone device) when the called device subscribes to the service. It is. In Japan and the United Kingdom, the timing at which the caller ID is transmitted is a silent section immediately before the call signal, and in the United States, it is a silent section between the first call signal and the next call signal. Thus, the calling party number is received by the called device before the receiver picks up the receiver of the called device (while the handset is on-hook). Therefore, if this service is used, the caller ID 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.
, The recipient can recognize the sender.

If the subscriber has subscribed to the calling telephone number display service, the caller ID is transmitted from the exchange to the called device, so that the call is transmitted and received between the exchange and the called device before the call.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the accompanying drawings. First, referring to FIG. 6, when a call is made, the call is transmitted / received between the called device subscribed to the calling telephone number display service ("number display" and "Caller ID") and the exchange. Various signals will be described.

As shown in FIG. 6, first, when a call is made from a calling device (not shown) to a called device 51, an exchange 50 is activated.
Performs the polarity inversion 41 of the telephone line connecting the called device 51 and the exchange 50 in order to transmit and receive various signals. Normally, the polarity of the telephone line is set to be negative on the L1 side 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 be positive and the L2 side is inverted to be negative.

When the exchange 50 performs the polarity inversion 41 of the telephone line, the information receiving terminal activation signal 4 indicating that the caller apparatus 51 is to be notified of the caller number (telephone number of the calling apparatus).
Send 2. By receiving the information receiving terminal activation signal 42, the called device 51 recognizes that the caller number is notified from the exchange 50. When the information receiving terminal activation signal 42 is received, a primary response signal 43 indicating that the caller number can be received is transmitted from the called device 51 to the exchange 50. The transmission of the primary response signal 43 is performed when the called device 51 closes the telephone line. 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 switching device 50 becomes 50Ω or more and 1700Ω or less, the exchange 50
It is determined that the next response signal 43 has been received.

Upon receiving the primary response signal 43, the exchange 50 receives the primary response signal 43. A MODEM signal 44 conforming to G.23 is transmitted to the called device 51. The caller number is transmitted to the called device 51 by the MODEM signal 44. Upon receiving the MODEM signal 44, the called device 51 transmits to the exchange 50 a reception completion signal 45 indicating that the caller number has been received by the MODEM signal 44.
The transmission of the reception completion signal 45 is performed by releasing the telephone line. When the resistance value of the telephone line measured from the exchange 50 becomes 1 MΩ or more, the exchange 50 determines that the reception completion signal 45 has been received.

Upon receiving the reception completion signal 45, the exchange 50 transmits to the called device 51 a calling signal 46 indicating that there is an incoming call from the calling device to the called device 51. Here, when the receiver is picked up by the receiver and goes into the on-hook state, the called device 51 closes the telephone line, and thereby the secondary call signal 47 indicating that the call has been answered.
To the exchange 50. As in the case of the primary response signal 43 described above, the exchange 50 determines that the resistance value of the telephone line (including the resistance value of the DC circuit of the called device 51) measured from the exchange 50 side is 50Ω or more and 1700Ω or less. It is determined that the secondary response signal 47 has been received.

When the exchange 50 receives the secondary response signal 47, it performs polarity reversal 48 of the telephone line. That is, due to the reversion of the polarity, the L1 side is returned to minus and the L2 side is returned to plus. After the polarity is restored, a call 49 is made between the caller (the caller of the calling device) and the receiver (the caller of the called device 51) via the telephone line and the exchange 50.

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 device 51 does not subscribe to the calling telephone number display service, signals 41, 46 to 48 excluding the parentheses in FIG. 6 are transmitted and received between the called device 51 and the exchange 50. Is done.

The exchange 50 first inverts 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.
After performing the polarity inversion, the exchange 50 transmits a call signal 46 to the called device 51. The called device 51 receives the call signal 4
6, the secondary response signal 47 is transmitted 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. Upon receiving the secondary response signal 47, the exchange 50 performs polarity reversal 48 of the telephone line, and returns the L1 side to minus and the L2 side to plus.
After the polarity is restored, a call 49 is made between the caller and the receiver via the telephone line and the exchange 50.

As described above, between the case where the calling telephone number display service is subscribed and the case where the calling telephone number display service is not subscribed, the switching between the exchange 50 and the called device 51 at the time of calling is performed. The transmitted and received signals are different. Therefore, in order to subscribe to the calling telephone number display service and display the calling number on the LCD of the called device 51,
It is necessary to prepare a telephone device compatible with the calling telephone number display service and to set a function (number display function) for receiving a caller number provided in the telephone device to an ON state.

If the subscriber has subscribed to the calling telephone number display service, the calling number is not always sent from the exchange 50. Specifically, when the calling device refuses to notify the telephone number, the exchange 50 sends the called device 5
No caller ID is sent to 1. However, even in this case, the information indicating that the caller ID cannot be transmitted is in MODE.
The M signal 44 is transmitted to the called device 51.

The facsimile apparatus 1 of this embodiment sets the number display function to the ON state by receiving the information receiving terminal activation signal 42 using the calling telephone number display service, and as a result, the caller number To receive. In the present embodiment, the exchange 50 in FIG. 6 will be described as the exchange 29 and the called device 51 will be described as the facsimile device 1.

FIG. 1 is an external perspective view of a facsimile machine 1 according to one embodiment of the present invention. As shown in FIG. 1, a handset 3 is attached to a side of a main body 2 of the facsimile apparatus 1. The receiver 3 is placed on a hook (not shown) provided on the main body 2 during a non-call, and is picked up and used during a call. The former is called an on-hook state, and the latter is called an off-hook state.

An operation panel 4 having a plurality of buttons 4a is provided at a front portion of an upper surface of the main body 2, and a liquid crystal display (L) for displaying a caller number is provided at a left rear portion of the operation panel 4.
CD) 5 is provided. The facsimile machine 1 is operated by depressing each button 4a provided on the operation panel 4, and the operation state and operation procedure are displayed on the LCD 5.

A document insertion slot 6 is provided at the rear of the operation panel 4 and the LCD 5. The original to be transmitted by facsimile is inserted into the original insertion slot 6 with the original surface facing downward, and after reading is performed, the original is sent from an original exit 7 provided on the front surface of the main body 2 and below the operation panel 4. Is discharged. A recording paper holder mounting portion 9 is provided at the rear of the document insertion slot 6, and a recording paper holder 10 capable of stacking and storing a plurality of recording papers is detachably mounted on 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.

FIG. 2 is a block diagram showing an electrical configuration of the facsimile machine 1. The facsimile device 1 includes a CPU 11, a ROM 12, an EEPROM 13, an RA
M14, image memory 15, audio memory 16, audio LSI
17, a network control unit (hereinafter referred to as "NCU") 19, a modem 20, a buffer 21,
A scanner 22, an encoding unit 23, a decoding unit 24, a printer 25, an operation panel 4, and an amplifier 27 are provided, and these are connected to each other via a bus line 30.

The NCU 19 performs line control, and the facsimile machine 1 is connected to the telephone line 31 via the NCU 19. NCU 19 is the exchange 2
9 as well as various signals such as a call signal 46 and a caller number 44 transmitted from the terminal 9 and a dial signal at the time of dialing according to the operation of the button 4a provided on the operation panel 4 to the exchange 29. Further, it transmits and receives analog voice signals during a call.

The CPU 11 controls various parts connected by the bus line 30 in accordance with various signals transmitted and received via the NCU 19 to execute facsimile operation and telephone operation, that is, data communication. ROM1
Reference numeral 2 denotes a non-rewritable memory storing a control program executed by the facsimile apparatus 1 and the like. The program shown in the flowcharts of FIGS.
It is stored in the OM12.

The EEPROM 13 is a rewritable nonvolatile memory, and data stored in the EEPROM 13 is retained even after the power of the facsimile apparatus 1 is turned off. This EEPROM 13 has a number flag 13a. The number flag 13a is a flag for storing a setting state of a number display function for receiving a caller number transmitted from the exchange 29.

If the signal transmitted first 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 signal first sent from the exchange 29 is not the information receiving terminal activation signal 42 but the calling signal 46, the function is set to the off state and the number flag 13a is turned off. When the subscriber has subscribed to the calling telephone number display service as described above, the signal first transmitted from the exchange 29 to the facsimile apparatus 1 is the information receiving terminal activation signal 42, whereas the subscriber is subscribed to the calling telephone number display service. Otherwise, the first signal sent from the exchange 29 to the facsimile machine 1 is the call signal 46.

The RAM 14 is a memory for temporarily storing various data when each operation of the facsimile machine 1 is executed, and has a state storage flag 14a. When the information receiving terminal activation signal 42 sent from the exchange 29 is received, the state storage flag 14a
This is a flag for saving the contents of 3a.

Here, the information receiving terminal start signal 42 and the extension calling signal (extension signal) are similar. Specifically, the information receiving terminal activation signal 42 is a signal that repeats ON for 0.5 s (second) and OFF for 0.5 s, whereas the extension signal is ON for 0.5 s, 2 s Is a signal that is repeatedly turned off. Therefore, if the facsimile apparatus 1 is used in an environment where extension lines and external lines are mixed, the facsimile apparatus 1 may mistakenly recognize the extension signal as the information receiving terminal activation signal 42.

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, since the number flag 13a and the setting of the number display function must be returned to the original state, the original state is stored (evacuated) in the state storage flag 14a.

Since the outside line calling signal 46 is a signal that repeats the ON of 1s and the OFF of 2s, the outside line calling signal 46 is not recognized as being mistaken for the information receiving terminal activation signal 42.

The image memory 15 is a memory for storing a communication history, image data, and a bit image for printing, and is an inexpensive large-capacity dynamic RA.
M (DRAM). The received image data is temporarily stored in the image memory 15 and is stored in the printer 2.
5, after the image memory 1
5 erased. Generally, the image data has a large capacity, but since the image data is deleted 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 device and an incoming message sent from the calling device. Image memory 1
5, the dynamic R which is an inexpensive large-capacity memory
It is composed of an AM (DRAM). Voice memory 1
The incoming message stored in 6 is erased by performing an erasing operation via the operation panel 4 or by receiving an erasing command sent from another device connected to the telephone line.

The voice LSI 17 performs a voice recognition process for converting an analog voice signal received by the NCU 19 into a digital voice signal, and converts a digital voice signal generated inside the facsimile apparatus 1 into an analog voice signal. NCU 19 and speaker 28 (amplifier 27)
This is for performing a speech synthesis process for outputting to the user.

The modem 20 modulates and demodulates the image information and transmits it, and also transmits and receives various procedure signals for transmission control. The buffer 21 stores a code transmitted and received between the other party's facsimile machine. This is for temporarily storing data including the converted image information. The scanner 22 is for reading an image from a document inserted into the document insertion slot 6.
2 encodes the image read.
The decoding unit 24 reads out the 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.

The operation panel 4 is used to perform various operations when the recipient sets the facsimile apparatus 1 and the like. The amplifier 27 sounds a speaker 28 connected to the amplifier 27. , For outputting a ring tone or voice.

Facsimile apparatus 1 constructed as described above
Are connected to the telephone line 31 via the NCU 19. This telephone line 31 is connected to an exchange 29 of the facsimile machine 1, and this exchange 29 is connected to another exchange via a telephone line 32. The other exchange is further connected to the calling device via a telephone line.

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 a process at the time of an incoming call.

As shown in FIG. 3, the facsimile machine 1 waits for an incoming call (S1: No), and when there is an incoming call (S1: Y).
es) 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: OF
F), it is determined whether or not the signal received in the process of S1 is the information receiving terminal activation signal 42 (S3). As a result of the determination, if the incoming signal is not the information receiving terminal activation signal 42 (S3: No), the telephone processing shown in FIG. 4 is executed (S12).

On the other hand, if the incoming signal is the information receiving terminal activation signal 42 (S3: Yes), the state storage flag 14a is turned off to store (save) the contents of the number flag 13a (S4). After the state storage flag 14a is turned off, the number flag 13a is turned on and a device for operating the number display function is set in response to the reception 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).

As described above, even if the number flag 13a is off and the setting for activating the number display function is not made, if the signal received first is the information receiving terminal activation signal 42, the number The settings for activating the display function are made. Therefore, the receiver who newly subscribes to the outgoing telephone number display service can set the number display function to the operating state without having to perform a complicated setting operation such as the operation of the button 4a.

In the process of S2, the number flag 13
If a 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 result of the determination is that the incoming signal is the information receiving terminal activation signal 42 (S7: Y
es), the state storage flag 14a is turned on to store (save) the contents of the number flag 13a (S8).
After the state storage flag is turned on, the primary response signal 4
Then, the telephone line is closed in order to transmit 3 (S6).

After the telephone line is closed (S6), it is determined whether a caller ID has been received from the exchange 29 (S9). Since the extension signal and the information receiving terminal activation signal 42 are similar as described above, it is considered that the extension signal is erroneously recognized as the information receiving terminal activation signal 42 in the processing of S3 and S7. As a result of the determination, when the caller number is received from the exchange 29 (S9: Yes), the signal recognized in the processing of S3 and S7 is the information receiving terminal activation signal 42
Therefore, the telephone line is opened to transmit the reception completion signal 45 to the exchange 29 (S10).

After releasing the telephone line, the caller number is displayed on the LCD 5 (S11). By looking at the display on the LCD 5, the receiver can recognize the sender before picking up the receiver 3. After displaying on LCD5,
The telephone processing shown in FIG. 4 is executed (S12).

In the process of S7, if the incoming signal is not the information receiving terminal activation signal 42 (S7: No),
It is checked whether 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 activation or stop state of the number display function (S12). On the other hand, if the incoming signal is not an extension signal, that is, an outside line calling signal 46 (S13: No), the number flag 13a is turned off and a device for stopping the number display function is set. (S14). After the setting, the telephone processing shown in FIG. 4 is executed (S12).

As described above, even when the number flag 13a is on and the number display function is in operation, if the first incoming signal is the calling signal 46, the setting for stopping the number display function is performed. Will be Therefore, even if the receiver who has subscribed to the calling telephone number display service does not subscribe to such a service, the receiver is not forced to perform complicated setting operations such as button 4a operation.
The number display function can be set to the stop state.

In the telephone processing shown in FIG. 4, first, it is confirmed whether or not the call signal 46 or the extension signal is continued (S20). If the signal continues (S20: Y
es) The speaker sounds to notify the recipient that there is an incoming call (S21). After the speaker rings, it is checked whether or not the receiver 3 is picked up, that is, whether or not the receiver 3 is in an off-hook state (S22). If the receiver 3 has not been picked up and is in the on-hook state (S22: N
o) The process proceeds to S20, and while the signal is continuing (S20: Yes), the processes from S20 to S22 are repeated. If the signal is interrupted during that time (S20: No), the telephone processing ends.

On the other hand, if the receiver 3 is picked up and goes off-hook (S22: Yes), the telephone line is closed to transmit the secondary response signal 47 to the exchange 29 (S22).
23). After the telephone line is closed, a call process is executed (S2).
4). The call processing (S24) is continued while the receiver 3 is in the off-hook state (S25: No). When the handset 3 is put down and becomes an on-hook state (S25: Yes), the telephone line is released (S26), and the telephone processing ends.
After the end of the telephone processing (S12), the processing shifts to S1 in FIG. 3 to wait for the next incoming call (S1).

In the process of S9, if the caller ID is not received from the exchange 29 (S9: No), S3
In step S7, the extension signal is transmitted to the information receiving terminal activation signal 4
It means that you have mistakenly recognized as 2,
The malfunction processing shown in FIG. 5 is executed (S15).

The malfunction process of FIG. 5 is a process performed when the 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, first, as shown in FIG. 5, a message "Please call again" is output to the calling device that is the destination of the extension (see FIG. 5). S30). As a result, it is possible to request a caller of the calling-side device that is the destination of the extension signal to make a recall.

After the output of the message, 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 received extension signal is transmitted to the exchange 29.
Since the number flag 13a was switched from off to on because the information receiving terminal activation signal 42 was mistakenly recognized as the information receiving terminal activation signal 42, the number flag 13a is turned off and the device for stopping the number display function is set. (S33). After the setting, the malfunction processing ends. On the other hand, if the state storage flag 14a is on (S
32: ON), since the content of the number flag 13a has not been changed, the process of S32 is skipped as it is, and
This malfunction processing ends. After the end of the malfunction process, the process shifts to S1 in FIG. 3 to wait for the next incoming call (S1).

As described above, by erroneously recognizing the extension signal as the information receiving terminal activation signal 42, even if the setting state of the number display function is erroneously switched to the operating state, the number display function is determined based on the state storage flag 14a. The setting state of such a function can be returned to the original state.

Therefore, there is an effect that the setting of the calling side information receiving means can be automatically switched to the stop state based on the signal sent from the exchange before the line is closed.

According to the telephone device of the third aspect, in addition to the effect of the telephone device of the second aspect, the information of the calling side device is notified from the signal received by the signal receiving means. When the signal is detected, the setting of the calling side information receiving means by the operating state setting means is switched to the operating state by the first switching means. Therefore, based on the signal sent from the exchange side before the line is closed, the setting of the calling side information receiving means is automatically switched to the operating state, so that the exchange side does not have to perform a troublesome switching operation on the receiver. This has the effect of being able to receive the information of the calling device that is sent.

According to the telephone device of the fourth aspect, in addition to the effect of the telephone device of the first or third aspect, furthermore, the detection means detects a signal indicating that information of the calling side device is to be notified. Is determined by the determining means to be a signal indicating another information that is not appropriate, 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 another information is erroneously detected as a signal indicating the notification of the information of the calling device, the setting of the calling information receiving means can be switched to the original state, which is unnecessary. This can prevent the problem that the setting state of the calling side information receiving means is switched.

According to the telephone device of the fifth aspect, in addition to the effect of the telephone device of the first or third aspect, furthermore, the detection means detects a signal indicating that the information of the calling side device is notified. Is determined by the determining means to be a signal indicating another information that is not appropriate, the setting of the calling side information receiving means by the operating state setting means is switched to the stopped state by the fourth switching means. Therefore, even if a signal indicating another information is erroneously detected as a signal indicating the notification of the information of the calling apparatus, the setting of the calling information receiving means can be switched to the stop state, and the signal is erroneously generated. It is possible to prevent a problem that the setting state of the calling side information receiving means is switched.

According to the telephone device of the sixth aspect, in addition to the effect of the telephone device of the fourth or fifth aspect, furthermore, detection of a signal indicating notification of information of the calling side device by the detecting means. Is not appropriate and is determined by the determination means to be a detection of a signal indicating another information, the message notification means sends a predetermined message to the calling apparatus to which the signal indicating the other information is transmitted. Is notified.
Therefore, by using, for example, a message requesting that the user make a call again as the predetermined message, it is possible to request a caller of the calling device to which the signal is to be transmitted to make a recall. This has the effect.

According to the telephone device of the seventh aspect, in addition to the effect of the telephone device of any one of the fourth to sixth aspects, the signal indicating the other information is a call signal of an extension. , Even in an environment where internal and external lines are mixed,
