BACKGROUND OF THE INVENTION
The present invention relates to a telephone device, and more particularly to a telephone device that can receive a telephone number of a counterpart device sent from an exchange side via a line.
[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. In this service, when the called side device subscribes to the service, the telephone number (caller number) of the other side device (calling side device, caller) is transferred from the exchange to the called side device (telephone device). It is a service to send to. 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 caller number is received by the called device before the user of the called device picks up the receiver of the called device (while the handset remains on-hook). Therefore, if this service is used, the caller number is displayed on the display (for example, a liquid crystal display (LCD)) of the called side device before picking up the handset of the called side device, and the called side device is displayed. The user can be made to recognize the caller.
[0003]
Some telephone devices can connect a cordless telephone device (child device). The handset and the phone unit of the base unit are connected by wireless communication or the like. If the handset and the base unit are installed in a remote place, one telephone line is connected to each of the handset and the base unit. Can be used on site.
[0004]
When such a master unit connected to the slave unit is subscribed to the above-described outgoing telephone number display service, the caller number sent by the service is received along with the incoming call from the counterpart device. Displayed on both the LCD and the slave LCD. When the handset of the master unit is picked up and the phone line is closed, the caller ID is displayed from the master unit to the slave unit in order to delete the caller number displayed on the slave unit. A command to delete is sent. On the other hand, when the connection key of the slave unit is pressed and the telephone line is closed with the slave unit, the display of the caller ID displayed on the LCD of the master unit is deleted. In other words, the display of the caller number other than the device that can make a call when the telephone line is closed is erased.
[0005]
[Problems to be solved by the invention]
However, in response to an incoming call from the partner device, the telephone line may be temporarily closed by the parent device or the child device, and then the phone may be transferred to another device. In this case, the caller ID display is erased on devices other than the device that was able to make a call when the telephone line with the other device is closed, so the user at the destination picks up or connects the handset. There is a problem that the telephone number of the other device, that is, the caller cannot be recognized before the key is pressed.
[0006]
The present invention has been made to solve the above-described problems. When a device capable of communicating with a partner device whose line is closed is switched from one device to another external device, It is an object of the present invention to provide a telephone device that can transmit information about a counterpart device to an external device.
[0007]

[0043]
When there is an incoming call and an incoming call from the counterpart device, the handset C memory 13d has the date and time when the incoming call or the incoming call is received or received, It is a memory for storing the telephone number of the counterpart device in association with each other. FIG. 3D schematically shows the configuration of the slave C memory 13d.
[0044]
Here, since the parent device memory 13a, the child device A memory 13b, the child device B memory 13c, and the child device C memory 13d are all configured in the same manner, only the configuration of the parent device memory 13a will be described below. A description of the other memories 13b, 13c, and 13d will be omitted.
[0045]
As shown in FIG. 3A, the base memory 13a is provided with an incoming call area 13e and an incoming call area 13f. In the incoming call area 13e, when there is an incoming call from the counterpart device, the date and time of the incoming call and the telephone number of the counterpart device for those related to the master unit 1 Is an area for storing and corresponding to each other. Specifically, when an incoming call is received from the counterpart device, if the master unit flag 14b described later is on, the date and time of the incoming call correspond to the telephone number of the counterpart device. It is attached and stored in the incoming call area 13e.
[0046]
On the other hand, when there is an incoming call from the counterpart device, the incoming area 13f shows the date and time of the incoming call and the telephone number of the counterpart device for those related to the main unit 1 in the incoming call. This is an area for storing data in association with each other. Specifically, when there is an incoming call from the counterpart device, and the master device 1 is the last device that can communicate with the counterpart device that received the call, the date and time of the incoming call and the counterpart side The telephone number of the device is associated with each other and stored in the incoming call area 13f.
[0047]
The RAM 14 shown in FIG. 2 is a memory for temporarily storing various data when each operation of the parent device 1 is executed. The destination number memory 14a, the parent device flag 14b, and the child device A flag 14c A slave unit B flag 14d, a slave unit C flag 14e, a command flag 14f, and an all history display flag 14g.
[0048]
The other party number memory 14a receives the incoming call (incoming call signal) before the telephone line is closed, and is sent from the exchange 29 by the outgoing telephone number display service described in the section of the prior art. It is a memory for temporarily storing a telephone number (caller number) of a device (calling side device, caller). For this reason, if the telephone number of the partner apparatus (sender) is not transmitted from the exchange 29 even if an incoming call is received, the contents of the partner number memory 14a are cleared to “0”. Accordingly, the contents of the destination number memory 14a are checked, and if it is not "0", it can be determined that the telephone number stored in the destination number memory 14a is an incoming call from the counterpart device (caller). If the contents of the other party number memory 14a are “0”, it can be determined that the telephone number of the other party apparatus (caller) that has received the call has not been transmitted from the exchange 29. Of course, as the other party device during a call, it is possible to use not only the other party device that has received a call to the main unit 1 but also the call destination device of the main unit 1 as the other party device during the call. is there. In this case, the telephone number of the call destination input by operating the key 4a on the operation panel 4 is stored in the destination number memory 14a.
[0049]
The base unit flag 14b is set to determine whether or not a ringing tone is sounded from the speaker 28 of the base unit 1 when an incoming call is received from the counterpart device, and the above-described destination number memory 14a. This is a flag for setting whether or not to display the contents of (i.e., the telephone number of the other party device that received the call) on the LCD 5 of the master unit 1.
[0050]
The cordless handset A flag 14c is used to set whether or not a ringing tone is emitted from the speaker of the cordless handset A when the incoming call is received from the counterpart device, and the contents of the counterpart number memory 14a. Is a flag for setting whether or not to transmit to the handset A.
[0051]
The cordless handset B flag 14d is set to determine whether or not a ringing tone is emitted from the speaker of the cordless handset B when the incoming call is received from the counterpart device, and the contents of the counterpart number memory 14a. Is a flag for setting whether or not to transmit to the slave unit B.
[0052]
The cordless handset C flag 14e is used to set whether or not a ringing tone is emitted from the speaker of the cordless handset C when the incoming call is received from the counterpart device, and the contents of the destination number memory 14a. Is a flag for setting whether or not to transmit to the child device C.
[0053]
Note that the data of the parent device flag 14b, the child device A flag 14c, the child device B flag 14d, and the child device C flag 14e (on / off switching) is previously stored on the operation panel 4 by the user of the parent device 1. These are set by operating the keys 4a.
[0054]
The command flag 14f is used when a device that can communicate with the counterpart device is switched from the master device 1 to any one of the slave devices A, B, and C, that is, when a call with the counterpart device is established. A command (telephone line release) requesting that a telephone line be released from the slave unit when the master unit 1 is relayed to one of the slave units A, B, and C. This is a flag for storing whether or not a request command is received. When a call with the other device is relayed from the master unit 1 to any one of the slave units A, B, and C, a telephone line release request command is received from the slave unit as the relay destination. Then, the command flag 14f is turned on. On the other hand, if a transfer signal or an intermediary signal is received from the intermediary slave unit, the command flag 14f is turned off.
[0055]
Here, the intermediary signal is sent from one device to another device (that is, from the parent device 1 to the first child device, or from the first child device to the other device with which the telephone line is closed). When switching from one unit to another, the transfer signal is sent from one slave unit to another slave unit (that is, between the slave units). This signal is transmitted to the base unit 1 when switching.
[0056]
In the process described later, if the command flag 14f is on, the incoming call history is stored in the incoming call area corresponding to the slave that is the transmission source of the telephone line release request command. Specifically, the date and time when an incoming call is received from the counterpart device and the telephone number of the counterpart device are associated with each other and stored in the incoming area. Usually, since the user of the device that was able to make a call at the end is the intended communication partner of the counterpart device, history information is stored for the device used by the counterpart device.
[0057]
When there is a history information transmission request from any one of the slave units A, B, and C, the all history display flag 14g is sent to the slave unit that is the source of the transmission request. Is a flag for storing whether or not to transmit only history information stored corresponding to. Since the same processing is performed for all the slave units A, B, and C, only the slave unit A will be described below.
[0058]
When a command requesting transmission of incoming call history (incoming call information request command) is received from handset A, if all history display flag 14g is on, all incoming calls stored in base unit 1 will be displayed. The contents (incoming call history) of the call areas 13e, 13g, 13i, and 13k and the contents of all the incoming areas 13f, 13h, 13j, and 13l are transmitted to the slave unit A. On the other hand, when the incoming call information request command is received from the child device A, if the entire history display flag 14g is off, the contents stored in the incoming call area 13g of the parent device 1 corresponding to the child device A and Only the content stored in the incoming area 13h of the parent device 1 corresponding to the child device A is transmitted to the child device A.
[0059]
As described above, when the all history display flag 14g is off, the contents of the incoming call area 13g corresponding to the child device A that is the transmission source of the incoming call information request command and the incoming call area 13h corresponding to the child device A are displayed. Only the stored contents are transmitted to handset A. Therefore, for the user of the slave unit A, only the contents of the incoming call area 13g corresponding to the slave unit A are used for the incoming call area 13e corresponding to all devices (the master unit and all the slave units A, B, C). , 13g, 13i, and 13k, the content of the incoming call area 13g corresponding to the handset A can be recognized without forcing a complicated operation of extracting from the content.
[0060]
Further, only the contents of the incoming call area 13g corresponding to the child device A that is the transmission source of the incoming call information request command and the contents stored in the incoming call area 13n corresponding to the child device A are transmitted to the child device A. Therefore, the contents of the incoming call areas 13e, 13i, 13k and the incoming call areas 13f, 13j, 13l corresponding to devices different from the child device A (parent device 1, child device B, and child device C) are stored in the child device A. It can be kept secret to the user.
[0061]
Further, a case will be described where a command (incoming information request command) for requesting transmission of incoming call history is received from handset A. When an incoming information request command is received from handset A, if all history display flag 14g is on, the contents of all incoming areas 13f, 13h, 13j, 13l stored in base unit 1 (incoming history) Is transmitted to handset A. On the other hand, when the incoming call information request command is received from the child device A, if the all history display flag 14g is off, only the contents of the incoming area 13f stored in the parent device 1 corresponding to the child device A are stored in the child device. It is sent to machine A. Note that the content of the all history display flag 14g (switching between on / off states) is set in advance by the key 4a operation on the operation panel 4 by the user of the parent device 1.
[0062]
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.
[0063]
The voice memory 16 is a memory for storing a response message sent to the counterpart device and an incoming message sent from the counterpart 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
[0064]
The audio LSI 17 converts the analog audio signal received by the NCU 19 into a digital audio signal, converts the digital audio signal generated inside the base unit 1 into an analog audio signal, and converts the NCU 19 and the speaker 28 ( This is for performing speech synthesis processing to be output to the amplifier 27).
[0065]
Here, the base unit 1 is connected to the telephone line 31 via the NCU 19. This telephone line 31 is connected to the exchange 29 on the base unit 1 side, and this exchange 29 is connected to another exchange via a telephone line 32. The other exchanges are further connected to the counterpart device via a telephone line.
[0066]
The detection circuit 33 is for detecting the polarity reversal of the telephone line 31 connecting the exchange 29 and the base unit 1. When a call is made from the counterpart device to the base unit 1, the exchange 29 first reverses the polarity of the telephone line 31 connecting the base unit 1 and the exchange 29. The polarity of the telephone line 31 is normally negative on the L1 side and positive on the L2 side of the telephone line 31 by a DC power supply (battery) (not shown) provided on the exchange 29 side. Therefore, when the polarity of the telephone line 31 is reversed, the L1 side of the telephone line 31 is inverted to plus and the L2 side is inverted to minus. After polarity reversal, various signals such as a call signal and a MODEM signal (caller number) are transmitted and received between the exchange 29 and the base unit 1. Note that the polarity of the telephone line 31 is determined by the user of the base unit 1 picking up the handset 3 according to the call signal, or the user of any one of the handset units A, B, and C. By depressing a connection key (key for closing the telephone line) (not shown), the L1 side is depolarized to the negative side and the L2 side is depolarized to the positive side, and the actual call is started.
[0067]
The modem 20 modulates and demodulates and transmits image information and communication data, and transmits and receives various procedure signals for transmission control. The buffer 21 is an encoding that is transmitted to and received from the counterpart device. For temporarily storing data including the image information. The scanner 22 is for reading a document inserted into the document insertion slot 6 as image data. The encoding unit 23 encodes image data read by the scanner 22. The decoding unit 24 reads out the 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.
[0068]
The operation panel 4 is for performing various operations when the operator performs settings of the parent device 1 and the like, and the amplifier 27 sounds a speaker 28 connected to the amplifier 27 to generate a ringing tone. And for outputting sound.
[0069]
The LCD 5 is for displaying an operation state and an operation procedure according to an operation of the key 4a on the operation panel 4, or displaying a telephone number of the counterpart device. If the above-mentioned base unit flag 14b is turned on when an incoming call is received from the counterpart device, the LCD 5 displays the telephone number (caller number) of the counterpart device that received the call. The On the other hand, if the base unit flag 14b is off, the caller number is not displayed on the LCD 5 even if there is an incoming call.
[0070]
Further, when the base unit flag 14b is on, there is an incoming call from the partner device, and when the telephone line is closed at the base unit 1 in accordance with the incoming call, the caller ID is displayed on the LCD 5 It becomes. On the other hand, when the telephone line is closed by another device (any one of the slave units A, B, and C) in response to the incoming call, the caller number displayed on the LCD 5 is displayed. Erased.
[0071]
Furthermore, when the device that can communicate with the other device is switched from the parent device 1 to any one of the child devices A, B, and C, the caller ID displayed on the LCD 5 is deleted. On the other hand, when the partner device is switched from one of the slave devices A, B, and C to the master device 1, the caller number is displayed on the LCD 5.
[0072]
Next, the operation of the facsimile machine (parent machine) 1 configured as described above will be described with reference to the flowcharts of FIGS. FIG. 4 is a flowchart showing the incoming call process. As shown in FIG. 4, the main unit 1 waits for the polarity reversal to be performed by the exchange 29 (S1: No), and when the polarity reversal is performed (S1: Yes), the calling telephone number display service described above is used. It is determined whether or not the caller number (the telephone number of the partner device) sent from the exchange 29 has been received (S2). If the caller number is received as a result of the determination (S2: Yes), the caller number is written in the destination number memory 14a (S3). Of the child device A flag 14c, child device B flag 14d, and child device C flag 14e, the child device whose content is on is set to transmit the contents of the destination number memory 14a from the parent device 1. . Therefore, after the writing in the process of S3, the contents of the other party number memory 14a, that is, the telephone number of the other party apparatus that has received the call, are transmitted to the slave unit whose flag is on (S4). When the contents of the destination number memory 14a are transmitted to the slave unit, the telephone number of the counterpart device that has received an incoming call on the LCD (not shown) of the slave unit to which the contents of the destination number memory 14a have been transmitted. It is displayed.
[0073]
Next, it is confirmed whether or not the parent machine flag 14b is on (S5). If the parent machine flag 14b is on (S5: ON), the contents of the destination number memory 14a are set to be displayed on the LCD 5, so that the contents of the destination number memory 14a are displayed on the LCD (S6). ). On the other hand, when the parent machine flag 14b is off (S5: OFF), the content of the destination number memory 14a is not set to be displayed on the LCD 5 of the parent machine 1, so the process of S6 is skipped.
[0074]
In the process of S2, if the caller refuses to send the phone number even if the base unit 1 is subscribed to the caller phone number display service, 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 destination number memory 14a is cleared to “0” (S7), and the fact that the caller number could not be received is stored.
[0075]
Next, a call signal is transmitted to the handset whose content is on among the handset A flag 14c, handset B flag 14d, and handset C flag 14e (S8). When a call signal is transmitted to the child device, a ringing tone is generated from a speaker (not shown) of the child device to which the call signal is transmitted. After the call signal is transmitted, it is confirmed whether or not the parent machine flag 14b is on (S9). If the parent machine flag 14b is on (S9: ON), a ringing tone is generated from the speaker 28 of the parent machine 1 (S10). On the other hand, if the parent device flag 14b is off (S9: OFF), the setting of ringing the ringing tone from the speaker 28 of the parent device 1 is not made, so the processing of S10 is skipped.
[0076]
As described above, when the base unit flag 14b is ON, a ringing tone is sounded from the speaker 28 of the base unit 1, and the contents of the destination number memory 14a (there is an incoming call) to the LCD 5 of the base unit 1 The phone number of the partner device) is displayed. In addition, a call signal is transmitted from the master unit 1 to the slave unit whose content is on among the slave unit A flag 14c, the slave unit B flag 14d, and the slave unit C flag 14e, and the other party number memory 14a The contents of are sent. That is, since the contents of the other party number memory 14a (the telephone number of the other party apparatus that received the call) are not displayed for the apparatus set not to ring the ringing tone, the privacy of the user of the telephone apparatus is reduced. It can be protected.
[0077]
Next, among the parent device flag 14b, the child device A flag 14c, the child device B flag 14d, and the child device C flag 14e, the date / time and the destination number memory 14a are transferred to the incoming call area corresponding to the device whose content is on. The contents (incoming call history) are written (S11). Specifically, when the parent device flag 14b and the child device A flag 14c are on and the child device B flag 14d and the child device C flag 14e are off, the incoming call area 13e of the parent device memory 13a. And the incoming call area 13g of the handset A memory 13b store the date and time when the incoming call is received from the counterpart device and the contents of the counterpart number memory 14a in association with each other. After the writing in the process of S11, the receiving process shown in FIG. 5 is executed (S12).
[0078]
As described above, of the parent device flag 14b, the child device A flag 14c, the child device B flag 14d, and the child device C flag 14e, an incoming call is received from the counterpart device to the incoming call area corresponding to the device whose content is on. The date and time and the contents of the destination number memory 14a are stored in association with each other. Therefore, the incoming call history can be stored in association with only the device that rings.
[0079]
The process at the time of reception in FIG. 5 is a process when a call signal is received from the exchange 29 in response to an incoming call from the partner apparatus. As shown in FIG. 5, first, in response to the transmission of the calling signal in the process of S8 in FIG. 4, a telephone line closing request command indicating that a telephone line closing is requested is sent to any of the slave units A to C. It is determined whether or not it has been received from the slave unit 1 (S22). If the telephone line closing request command is not received as a result of the determination (S22: No), it is confirmed whether or not the handset 3 of the base unit 1 is in an off-hook state (S23). If the handset 3 is not picked up and remains in the on-hook state (S23: No), the process proceeds to S22, and the processes of S22 and S23 are repeated.
[0080]
On the other hand, when the telephone line closing request command is received from the slave unit in the process of S22 (S22: Yes), the telephone line is closed (S24). After closing, the display of the caller number is erased from the LCD 5 of the base unit 1 (S25), and the caller number is sent to all the handset except the handset which is the transmission source of the telephone line close request command. A command for deleting the display is transmitted (S26).
[0081]
If no intermediary signal or transfer signal is received after the transmission of the command (S27: No, S28: No), until a telephone line release request command indicating that a telephone line release request is received from the slave unit ( S29: No), the processing from S27 to S29 is repeated. During this time, telephone processing is executed in the slave unit that requested closing of the line.
[0082]
Here, as described above, the agency signal sounds a ringing tone from another device when switching from one device to another device that can communicate with a partner device whose telephone line is closed. It is a signal to make it. The transfer signal is a signal transmitted to the parent device 1 when switching a device that can communicate with a partner device whose telephone line is closed from one child device to another child device.
[0083]
When an intermediary signal is received in the process of S27 (S27: Yes), an intermediary signal reception process (see FIG. 7) described later is executed (S51), and when a transfer signal is received in the process of S28 ( (S28: Yes), a transfer signal reception process (see FIG. 8) described later is executed (S71).
[0084]
In the process of S23, if the handset 3 of the base unit 1 is picked up and enters the off-hook state (S23: Yes), the telephone line is closed (S30), and the caller ID is sent to all the slave units A, B, and C. A command for deleting the display is transmitted (S31). Thereafter, telephone processing of the base unit 1 is executed (S32). If the intermediary key 4c is not pressed during the telephone processing (S33: No), the receiver 3 is placed on the hook and the receiver 3 is in the on-hook state (S34: No), from S32 to S34. Repeat the process.
[0085]
On the other hand, if the agency key 4c is pressed in the process of S33 (S33: Yes), an agency process (see FIG. 6) described later is executed (S35). After completing this agency process, the contents of the command flag 14f are confirmed (S36). The command flag 14f is set in an agency process described later, and is a flag for storing whether or not a telephone line release request command has been received from the slave unit.
[0086]
If the command flag 14f is off (S36: OFF), the reception process is terminated. On the other hand, when the command flag 14f is on (S36: ON), when the handset 3 is on-hook in the process of S34 (S34: Yes), or when a telephone line release request command is received in the process of S29 (S29: Yes), the telephone line is released (S37), and finally the incoming call history is written in the incoming call area corresponding to the device that was able to talk to the other device (S38).
[0087]
The history information is written by storing the date and time when the incoming call is received from the counterpart device and the telephone number of the counterpart device in the incoming area. Specifically, if it is determined to be on in S36, the incoming call history is written in the incoming call area corresponding to the preceding slave unit that was interleaved in the process of S42 in FIG. 6 to be described later, and in the process of S34 If it is determined Yes, the incoming call history is written in the receiving area 13f of the base unit 1, and if it is determined Yes in the process of S29, there is a telephone line closing request in the process of S22. Each incoming call history is written in the incoming call area corresponding to the handset.
[0088]
After the reception history is written in the process of S38, the reception process is terminated. Note that after completion of the reception process (S12), the process shifts to FIG. 4 and the incoming call process of FIG. 4 ends.
[0089]
In this way, the incoming call history is stored in the incoming call area corresponding to the device that was able to talk to the partner device whose telephone line is closed last. This is because it is usually considered that the user of the device that made the last call is the intended call partner of the other device.
[0090]
Next, the agency process (S35 in FIG. 5) will be described with reference to FIG. The intermediary process in FIG. 6 is a process for switching a device that can communicate with a partner device whose telephone line is closed from the parent device 1 to any one of the child devices A, B, and C. It is. As shown in FIG. 6, first, it waits until the numeric keypad 4b for designating a handset that can communicate with the counterpart device is input (S41: No), and if the numeric keypad 4b is pressed (S41: Yes), An agency signal is transmitted to the slave unit corresponding to the number input by pressing the numeric keypad 4b (S42). As a result, a ringing tone is generated in the slave unit that is the transmission destination of the agency signal.
[0091]
After transmitting the agency signal, the contents of the destination number memory 14a are transmitted to the slave unit corresponding to the number input with the numeric keypad 4b (S43). After the transmission, it waits until a telephone line closing request command is received from the slave unit in response to the ringing tone (S44: No), and if the telephone line closing request command is received (S44: Yes), the counterpart device Is switched from the parent device 1 to the child device corresponding to the number input with the numeric keypad 4b (S45). After switching, the display of the caller ID is erased from the LCD 5 of the base unit 1 (S46). If no intermediary signal or transfer signal is received after erasure (S47: No, S48: No), the processing from S47 to S49 is performed until a telephone line release request command is received from the slave unit (S49: No). repeat. During this time, telephone processing is executed in the slave unit.
[0092]
On the other hand, if a telephone line release request command is received from the slave unit (S49: Yes), the command flag 14f is turned on to store the reception of this command (S50), and this agency processing is terminated.
[0093]
If an intermediary signal is received from the slave in the process of S47 (S47: Yes), an intermediary signal reception process (see FIG. 7) described later is executed (S51). After the process at the time of receiving the reception signal is completed, or when a transfer signal is received in the process of S48 (S48: Yes), the command flag 14f is turned off (S52), and the process of the transfer is ended.
[0094]
In this way, in the agency process, the device that can communicate with the counterpart device is switched from the parent device 1 to the child device corresponding to the number input with the numeric keypad 4b. Even in such a case, since the telephone number of the counterpart device whose telephone line is closed is transmitted to the slave unit, the telephone number of the counterpart device can be notified to the user of the slave unit. .
[0095]
Next, with reference to FIG. 7, the process at the time of reception of an agency signal will be described. The process at the time of reception of an agency signal in FIG. 7 is a process executed when an agency signal is received from a slave unit that can communicate with the counterpart device. That is, when an agency signal is received in the process of S27 of FIG. 5 (S27: Yes), when an agency signal is received in the process of S47 of FIG. 6 (S47: Yes), or in the process of S77 of FIG. This process is executed when a signal is received (S77: Yes). In the following description, the same parts as those in the reception process shown in FIG. 5 are denoted by the same reference numerals and the description thereof is omitted, and only different parts will be described.
[0096]
As shown in FIG. 7, first, the contents of the destination number memory 14a are displayed on the LCD 5 (S62). After the display, it is confirmed whether or not the handset is in an off-hook state (S63). If the handset is not picked up and remains in the on-hook state (S63: No), the process proceeds to S62, and the processes from S62 to S63 are repeated. On the other hand, if the handset is picked up and enters the off-hook state (S63: Yes), the device that can communicate with the partner device is switched from the slave device that is the transmission source of the agency signal to the master device 1 (S64). After switching, a command for deleting the display of the caller ID is transmitted to the slave unit that is the transmission source of the agency signal (S65).
[0097]
As described above, even when a device that can communicate with the other device is switched from the child device to the parent device 1, the telephone number of the other device whose telephone line is closed is displayed on the LCD 5 of the parent device 1. Therefore, the user of base unit 1 can be notified of the telephone number of the counterpart device.
[0098]
Next, with reference to FIG. 8, the process at the time of transfer signal reception will be described. The process at the time of receiving a transfer signal in FIG. 8 is a process executed when a transfer signal is received from a slave unit that can communicate with the counterpart device. That is, this process is executed when a transfer signal is received in the process of S29 in FIG. 5 (S29: Yes) or when a transfer signal is received in the process of S48 of FIG. 6 (S48: Yes).
[0099]
As shown in FIG. 8, first, an agency signal is transmitted to the slave unit indicated by the data of the transfer signal (S72). As a result, the ringing tone is sounded in the slave unit that is the transmission destination of the agency signal. After transmitting the agency signal, the contents of the destination number memory 14a are transmitted to the slave unit indicated by the data of the transfer signal (S73). After transmission, it waits until a telephone line closing request command is received from the handset indicated by the data of the transfer signal in response to the ringing tone (S74: No), and if a telephone line closing request command is received (S74: Yes). ), The handset that can communicate with the counterpart device is switched from the handset that is the source of the transfer signal to the handset indicated by the data of the transfer signal (S75). After switching, a command for deleting the display of the caller ID is transmitted from the LCD of the slave unit that is the transmission signal transmission source to the slave unit (S76).
[0100]
In this way, even when the slave unit that can communicate with the counterpart device is switched from one slave unit to another slave unit, the telephone number of the counterpart device whose telephone line is closed to the other slave unit Is transmitted, it is possible to notify the user of the other slave unit of the telephone number of the counterpart device.
[0101]
If no intermediary signal or transfer signal is received after transmission (S77: No, S78: No), the processing from S77 to S79 is repeated until a telephone line release request command is received (S79: No). During this time, telephone processing is executed in the slave unit.
[0102]
On the other hand, when a new transfer signal is received in the process of S78 (S78: Yes), the process proceeds to S72, and an agency signal is transmitted to the slave unit indicated by the data of the new transfer signal (S72). ). Further, in the process of S77, when an agency signal is received (S77: Yes), the agency signal reception process shown in FIG. 7 is executed. When the process at the time of receiving the relay signal is finished, the process at the time of receiving the transfer signal is finished.
[0103]
In the process of S79, when a telephone line release request command is received from the slave unit indicated by the transfer signal data (S79: Yes), the telephone line is released (S80). After the release, the incoming call history is written in the incoming call area corresponding to the slave indicated by the transfer signal data (S81), and the transfer signal reception process is terminated.
[0104]
Next, the history information transmission process will be described with reference to FIG. The history information transmission process is a process performed when a command for transmitting history information is received from the slave unit. As shown in FIG. 9, it waits until an incoming call information request command or an incoming call information request command is received (S91: No, S92: No), and when an incoming call information request command is received (S91: Yes), It is determined whether or not the all history display flag 14g is on (S93). As a result of the determination, if the all history display flag 14g is on (S93: ON), the contents of all the incoming call areas 13e, 13g, 13i, 13k and the contents of all the incoming call areas 13f, 13h, 13j, 13l. Are transmitted to the slave device of the command transmission source (S94). On the other hand, when the all history display flag 14g is off (S93: OFF), the contents of the incoming call area and the contents of the incoming area corresponding only to the command transmission source slave unit are transmitted to the command transmission source slave unit. (S95).
[0105]
If an incoming information request command is received in the process of S92 (S92: Yes), it is determined whether or not the all history display flag 14g is on (S96). As a result of the determination, if the all history display flag 14g is on (S96: ON), the contents 13f, 13h, 13j, and 13l of all the incoming areas are transmitted to the command transmission source slave (S97). On the other hand, the contents of the receiving area corresponding only to the command transmission source slave unit are transmitted to the command transmission source slave unit (S98).
[0106]
As described above, when the all history display flag 14g is OFF, only history information corresponding to the slave unit that is the transmission source of the incoming call information request command or the incoming information request command is sent to the slave unit that is the command transmission source. Sent. Therefore, the history information corresponding to the slave unit is not imposed on the user of the slave unit without forcing a complicated operation of extracting the history information corresponding to only the slave unit from the history information corresponding to all devices. Only can be recognized. Also, by transmitting only the history information corresponding to the slave device that is the command transmission source to the slave device, the history information stored corresponding to a device different from the slave device is transmitted to the user of the slave device. Can be kept secret.
[0107]
In the present embodiment, the process of S3 corresponds to the reception storage means described in claims 1 to 4, and the process of S8 corresponds to the ringing designation means. The first transmission unit according to claims 1 and 2 corresponds to the processing of S43 and S73.
[0108]
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.
[0109]
For example, in the present embodiment, the case where an incoming call is received from the counterpart device in the flowcharts shown in FIGS. 4 to 8 is described. However, any one of the master unit 1 and the slave units A, B, and C is described. Of course, it is possible to make a call from the device to the other device. In this case, the telephone number of the other party device that is the call destination is stored in the other party number memory 14a, and the contents of the other party number memory 14a are displayed on the destination device at the time of the transfer. Alternatively, the contents of the destination number memory 14a may be transmitted to the destination slave unit.
[0110]
In the present embodiment, in the flowcharts shown in FIGS. 5 to 8, the telephone number of the partner apparatus sent by the calling telephone number display service is written in the partner number memory 14a, and the contents of the partner number memory 14a are stored in the partner apparatus. It was displayed on a device that can talk. However, the telephone number of the partner apparatus written in the partner number memory 14a is not necessarily limited to the telephone number sent from the exchange 29 by the calling telephone number display service, but sent from the exchange 29 by the busy information notification service. The telephone number of the other device to be used may be used. Here, in-call information notification service, when the base unit 1 is subscribed to a so-called call waiting service, the telephone number (caller number) of the other side device that is newly called during the call is transferred from the exchange 29 to the base unit 1. It is a service to send.
[0111]
In the facsimile apparatus (master unit) 1 of the present embodiment, in the processes of S38 and S81, the incoming call history is written in the incoming call area corresponding to the apparatus that was able to talk to the other party apparatus that is closed at the telephone line. It is. However, instead of this, the incoming call history may be written in an incoming call area corresponding to a device in which the callable time with the counterpart device exceeds a predetermined time. With this configuration, since the user of the device that has been talking over a predetermined time is usually the intended communication partner of the other device, the incoming call history is stored for the device used by the other device. It can be memorized. Further, the incoming call history may be written in the incoming call area corresponding to the device having the longest call time with the counterpart device. According to this configuration, since the user of the device that has been talking for the longest time is the intended communication partner of the counterpart device, history information is stored in the device used by the counterpart device. Can do it.
[0112]
In the present embodiment, in the processing of S43 and S73, the contents of the other party number memory 14a, that is, the telephone number of the other party apparatus whose telephone line is closed are transmitted to the slave unit that is the destination. 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 the stored name of the counterpart device is stored in the contents of the destination number memory 14a. Alternatively, it may be configured to transmit to the slave unit that is the destination.
[0113]
In the present embodiment, in the processing of S11, S38, and S81, the telephone number of the partner apparatus whose telephone line is closed is used as the incoming call history or the incoming call history. 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 the stored name of the counterpart device is stored as an incoming call history or an incoming call history. You may comprise so that it may do.
[0114]
【The invention's effect】
According to the telephone device of the first aspect, since the information on the counterpart device is not notified to the external device that does not ring the ringing tone, there is an effect that the privacy of the user of the telephone device can be protected. Furthermore, when the incoming call is received from the master unit or any one of the slave units that can communicate with the counterpart device whose line is closed, the output of the other device information and ringing is not specified when the call is received. When a switching request for closing of a line is made to another slave by one switching request means or another switching request means, the information on the partner device and the output of the ringing tone are designated by the ring designation means. Regardless, the information on the counterpart device stored in the reception storage unit is transmitted to the other slave unit as the switching destination by the first transmission unit. Therefore, even when a device that can communicate with a partner device whose line is closed can be switched from one device to another slave device, information on the partner device is sent to the user of the other slave device. There is an effect that it can be notified.
[0115]
According to the telephone device according to claim 2, in addition to the effect of the telephone device according to claim 1, the main device or any of the child devices capable of making a call with the counterpart device whose line is closed When a request for switching the closing of a line is made to the slave unit by the one switching requesting means or the other switching requesting means, the partner based on the identification information of the counterpart device stored in the calling storage means The information on the side device is transmitted to the other slave unit that is the switching destination by the second transmission unit. Therefore, even when a device that can communicate with a partner device whose line is closed can be switched from one device to another slave device, information on the partner device is sent to the user of the other slave device. There is an effect that it can be notified.
