A reading unit 21, a printing unit 22, an operation unit 23, a display unit 24, and a wireless communication unit 25 are connected to the gate array 16. A public telephone line 28 is connected to the NCU 11.
[0021]
  The CPU 10 controls the operation of the entire facsimile apparatus. The CPU 10 also controls various processes relating to telephone book data, which will be described later. The NCU 11 is connected to the public telephone line 28 and performs network control. The RAM 12 provides a work area for the CPU 10 and a temporary storage area for various data. The modem 13 performs modulation / demodulation of facsimile data and voice data. The ROM 14 stores programs to be executed by the CPU 10 and setting information. The NVRAM 15 stores phone book data. The gate array 16 functions as an interface between the CPU 10 and the units 21 to 25. The codec 17 encodes and decodes facsimile data and voice data. The DMAC 18 mainly writes data to and reads data from the RAM 12.
[0022]
  The reading unit 21 includes an image sensor, an LED light source, and the like, and reads images such as characters and figures from a document. The printing unit 22 prints an image such as a character or a graphic by using, for example, an inkjet method.

[0023]
  To summarize the main points, the name of the other party (partner information) and the telephone number are stored as phone book data together with the management number in the NVRAM 15 of the parent machine A, and the parent machine A centrally manages the phone book data. . On the other hand, the slave units B1 and B2 do not have a memory for storing the phone book data, and each of the slave units B1 and B2 requests the master unit A to transfer the phone book data as necessary.
[0024]
  FIG. 2 is an explanatory diagram for explaining the structure of telephone directory data. As shown in this figure, for example, the management number “001” is associated with the partner name “A” and its telephone number “01234456789”, and the management number “002” is associated with the partner name “B”. ”And the telephone number“ 0333666699 ”. Similarly, the other management number is associated with the name of the other party and the telephone number. That is, one phone book data is stored for each management number. Such a management number can be assigned up to several hundreds, and telephone book data can be stored in hundreds.
[0025]
  The NVRAM 15 also stores an attribute management table that defines which phone book data can be used for each of the parent device A and the child devices B1 and B2. According to this attribute management table, for example, the phone book data that can be used by the parent device A are management numbers 001, 003, and 005, the phone book data that can be used by the child device B1 are management numbers 002 to 005, and The phone book data that can be used on the machine B2 are management numbers 003, 004, and 006.
[0026]
  Such phone book data and contents of the attribute management table can be newly registered, changed, or deleted using the operation unit 23 and display unit 24 of the main unit A. In addition, even if the slave units B1 and B2 are operated, the phone book data and the contents of the attribute management table can be newly registered, changed, or deleted, and at this time, between the master unit A and the slave units B1 and B2 The phone book data is exchanged.
[0027]
  Further, when a call is made to the other party using the handset B1 or B2, or when a caller telephone number is notified when an incoming call is received from the outside through the public telephone line 28, the base unit A and the handset B1, Phone book data is exchanged with B2.
[0028]
  Next, the operation in each usage mode will be described.
[0029]
  FIG. 3 is a sequence diagram showing a procedure for newly registering phone book data using handset B1.
[0030]
  First, as shown in FIG. 3A, when the user performs an operation for phone book registration using the slave unit B1, the slave unit B1 requests the master unit A to start registration of phone book data. And a command for confirming the management number that is actually available are transmitted to the main unit A.
[0031]
  In the base unit A that has received such a command, the management number in the phone book data is checked, and if there is an available number, a command to that effect is returned to the handset B1.
[0032]
  In response to this, in the slave unit B1, when the name and telephone number of the other party to be newly registered are input by the user, they are requested to be registered in the master unit A as phone book data. At this time, it can be notified that the phone book data related to the registration request is used only by the slave unit B1.
[0033]
  In the base unit A, the phone book data registered in the NVRAM 15 and the content of the phone book data related to the registration request are collated, and if there is no phone book data with the matching content, the content (to be newly registered) Destination name and phone number) are registered. At this time, if it is reported that the contents of the registration request are used only by the slave unit B1, “○” is added to the corresponding phone book data in the attribute management table as shown in FIG.
[0034]
  Then, a registration completion command is transmitted from the parent device A to the child device B1, and a message “Registered” is displayed in the child device B1 that has received the command.
[0035]
  On the other hand, as shown in FIG. 3B, as a result of collating the phone book data registered in the NVRAM 15 with the content of the phone book data related to the registration request in the base unit A, the phone book data having the matching contents has already been found. If it exists, the registered phone book data is transferred to the child device B1 together with a command indicating registered.
[0036]
  In the slave unit B1, messages such as “The same number has been registered” and “Do you want to register separately?” Are displayed together with the received registered phone book data.
[0037]
  In response to this, when the user selects “register separately”, the parent device A is required to forcibly register the destination name and the telephone number inputted as new registration as telephone directory data. At this time, if the user selects “not register”, the process for new registration ends.
[0038]
  In base unit A that has received a request to be forcibly registered, the name of the other party and the telephone number relating to the request are registered in the free management number.
[0039]
  Thereafter, a registration completion command is transmitted from the parent device A to the child device B1, and a message “Registered” is displayed in the child device B1 that has received the command.
[0040]
  In this manner, the phone book data can be newly registered in the NVRAM 15 of the parent device A by operating the child device B1.
[0041]
  Next, FIG. 4 is a sequence diagram showing a procedure when browsing / deleting / changing the phone book data using the handset B1.
[0042]
  First, as shown in FIG. 4A, when the user performs an operation for browsing the phone book using the slave unit B1, the slave unit B1 requests the master unit A to start browsing the phone book data. And a command for requesting transfer of telephone directory data are transmitted to the main unit A.
[0043]
  The base unit A that receives these commands transfers only the phone book data associated with the handset B1 with reference to the attribute management table (see FIG. 2).
[0044]
  When the completion of the transfer of the phone book data is transmitted from the main unit A to the sub unit B1, the sub unit B1 displays, for example, a scroll display of the contents of the received phone book data (the name of the other party and the telephone number) together with the management number. Is done. At this time, the phone book data received by handset B1 is temporarily stored in a display memory in handset B1. When the received phone book data overflows the display memory, the remaining phone book data is sequentially transmitted from the main unit A to the sub unit B1 in response to the scroll operation, and the display memory is used, for example, by the FIFO method. . Note that the phone book data may be exchanged for each data group in which the first character of the destination name is classified by “A line”, “K line”, or the like. In this case, for example, every time the slave unit B1 moves from “A” to “F”, a group of phone book data is transmitted from the master unit A to the slave unit B1.
[0045]
  Thus, the telephone directory data displayed on the slave unit B1 can be selected as a call destination. For example, when the destination name “B” is selected as a call destination, a call request is made from the slave unit B1 to the base unit A, and at the same time, it corresponds to the destination name “B” as the call destination (selection). The management number is transmitted to the main unit A.
[0046]
  In the main unit A, a telephone number is acquired from the telephone directory data corresponding to the received (selected) management number, and the telephone number is sent to the public telephone line 28 after the line is closed. At this time, a message such as “dialing” is displayed on the slave unit B1, and a call path is formed through a modem or a wireless communication unit (not shown). Thereafter, in the base unit A, a call path is formed through the NCU 11, the modem 13, and the wireless communication unit 25, and the call completion is transmitted from the base unit A to the handset B1. In the handset B1 that has received the call completion notification, a message such as “busy” is displayed.
[0047]
  On the other hand, as shown in FIG. 4B, in the state where the phone book data is displayed on the handset B1, the user can select an erase number to erase the desired phone book data. For example, when “002” corresponding to the destination name “B” is selected as the erasure number, the erasure number is transmitted from the slave unit B1 to the master unit A, and the erase number is transmitted to the master unit A at the same time.
[0048]
  In the master unit A, the phone book data of the management number corresponding to the received deletion number is deleted. Thereafter, the erasure completion is transmitted from the parent device A to the child device B1, and a message such as “erased” is displayed in the child device B1 that has received the erasure completion notification.
[0049]
  Further, as shown in FIG. 4C, the user can change the contents of desired phone book data in a state where the phone book data is displayed on the child device B1. For example, the destination name “B” and its telephone number “03336666999” can be changed to “B ′”, “03 *******”, or the like. At this time, for example, if “002” corresponding to the destination name “B” is selected as the change number, and the content is changed and then confirmed, a change in the phone book data is requested from the slave unit B1 to the master unit A, At the same time, the change number and change contents are transmitted to the main unit A.
[0050]
  In base unit A, the contents of the telephone book data of the management number corresponding to the received change number are rewritten with the changed contents. Thereafter, the completion of the change is transmitted from the parent device A to the child device B1, and the message “changed” is displayed in the child device B1 that has received the notification of the change completion.
[0051]
  In this way, the contents of the phone book data can be deleted / changed by operating the handset B1. Further, it is possible to refer to the phone book data of the parent device A from the child device B1 and to transmit a desired telephone number included in the phone book data from the child device B1 to the parent device A.
[0052]
  Next, FIG. 5 is a sequence diagram showing a procedure when an incoming call is received from the other party.
[0053]
  First, as shown in FIG. 5 (a), when there is a notification of the caller telephone number when an external line is received from the public telephone line 28, the base unit A has been registered as the caller telephone number and the phone book data. Match the phone number of. If there is no coincident registered telephone number, base unit A emits a ringing tone and transmits an external line calling command and a source telephone number to all the handset units B1 and B2. At this time, the caller telephone number is displayed on the display unit 24 of the main unit A.
[0054]
  When each of the slave units B1 and B2 receives the command for calling the outside line and the caller telephone number, it makes a ringing tone and displays the caller telephone number on the display unit 44 in the same manner as the parent machine A. If there is no notification of the caller telephone number when an outside line is received, the parent machine A and the child machines B1 and B2 simply ring the ringing tone and do not display the caller telephone number.
[0055]
  On the other hand, as shown in FIG. 5B, when the caller telephone number matches the registered telephone number, the main unit A sounds the ringing tone in the same manner as described above. If the telephone number is “03336666999”, the partner name “B” corresponding to the telephone number is read from the telephone book data, and the command for calling the outside line and the partner name for the handset B1 that is made available in the attribute management table. “B” is transmitted. That is, the destination name “B” of the telephone number “03336666999” is not transmitted to the slave unit B2 that is disabled in the attribute management table. At this time, the destination name “B” corresponding to the caller telephone number “03336666999” is displayed on the display unit 24 of the parent device A.
[0056]
  In the handset B1 that has received the command for calling the outside line and the name of the other party, a ringing sound is generated as in the case of the parent machine A, and the other party name is displayed on the display unit 44 of the handset B1.
[0057]
  As described above, when there is a notification of the caller telephone number when an outside line is received, the name of the other party can be displayed not only in the parent device A but also in the child devices B1 and B2 based on the attribute management table. The base unit A is similar to the above-mentioned phone book data, and automatically creates incoming call history data that associates the caller's phone number or destination name with the date and time of incoming call, giving history numbers in the order of incoming call history. ing.
[0058]
  Next, FIG. 6 is a sequence diagram showing a procedure for making a call or registering a phone book with reference to the incoming call history data by the slave unit B1.
[0059]
  First, as shown in FIG. 6A, when a user performs an operation for browsing incoming call history data using the slave unit B1, the slave unit B1 starts browsing incoming history data from the master unit A. And a command for requesting transfer of incoming call history data are transmitted to base unit A.
[0060]
  In the base unit A that receives these commands, the incoming call history data is selected and transferred to the handset B1.
[0061]
  When the completion of transfer of the incoming call history data is transmitted from the parent device A to the child device B1, the contents of the received call history data (the incoming date and time, the name of the other party, and the telephone number) are scrolled, for example, in the child device B1. Is done. At this time, the incoming call history data received by handset B1 is temporarily stored in a display memory in handset B1. When the received incoming call history data overflows the display memory, the remaining incoming call history data is sequentially transmitted from the parent device A to the child device B1 in response to the scroll operation, and the display memory is used, for example, by the FIFO method. .
[0062]
  Thus, the incoming call history data displayed on the handset B1 can be selected as a call destination. For example, when the destination name “B” in the incoming call history data is selected as a call destination, a call request is made from the slave unit B1 to the base unit A, and at the same time, the destination name “B” as the call destination is set. The corresponding selection history number is transmitted to the main unit A.
[0063]
  In the main unit A, the telephone number is acquired from the received call history data of the selected selection history number, and the telephone number is sent to the public telephone line 28 after the line is closed. The subsequent processing is the same as the processing procedure shown in FIG.
[0064]
  On the other hand, as shown in FIG. 6B, in a state where the incoming call history data is displayed on the slave unit B1, the user can select the desired incoming call history data to be incorporated into the phone book data. For example, when a history number corresponding to a caller telephone number “01122223333” that does not exist in the registered phone book data is designated and the name of the corresponding destination is entered by the user, the history number and the destination number together with a command for phone book registration request The name is transmitted to the main unit A.
[0065]
  Base unit A obtains the telephone number “01122223333” of the received history number from the incoming call history data, and further uses the telephone number “01122223333” and the name of the other party directly transmitted by the user as phonebook data. Registered to the management number.
[0066]
  Then, a registration completion command is transmitted from the parent device A to the child device B1, and a message “Registered” is displayed in the child device B1 that has received the command.
[0067]
  In this way, it is possible to refer to the incoming call history data of the parent device A from the child devices B1 and B2, and register the incoming call history data without the destination name in the parent device A as the phone book data.
[0068]
  Therefore, according to the above-described embodiment, the base unit A centrally manages the phone book data, and the slave units B1 and B2 do not need a nonvolatile memory such as NVRAM for permanently storing the phone book data. Therefore, the entire system can be configured at a low cost.
[0069]
  Further, the phone book data managed by the base unit A can be newly registered, changed, or deleted from the handset B1 and B2, and the phone book data is stored in the handset B1, B2 based on the attribute management table. Separately, it can be used for outgoing calls and incoming calls.
[0070]
  Next, another embodiment will be described.
[0071]
  FIG. 7 is an explanatory diagram for explaining the structure of telephone directory data according to another embodiment. As shown in FIG. 7A, the phone book data itself is the same as in the above-described embodiment, but the base unit A does not include the attribute management table as described above.
[0072]
  That is, as shown in FIG. 7B, each of the slave units B1 and B2 includes a management number list that associates a management number that can be used with each other and a partner name. In order to save the management number list, each of the slave units B1 and B2 is provided with a nonvolatile memory such as NVRAM (not shown).
[0073]
  For example, when the phone book data is newly registered in the parent device A using the child device B1, the same destination name as the phone book data is also created in the management number list of the child device B1. Further, if the name of the other party included in the phone book data of the parent device A is changed using the child device B1, the changed contents are reflected in the management number list of the child device B1. Further, when the phone book data of the parent device A is deleted using the child device B1, the corresponding management number and destination name are also deleted from the management number list of the child device B1.
[0074]
  Also, when calling the other party using the handset B1 or when receiving a caller telephone number when receiving an incoming call from the outside through the public telephone line 28, between the base unit A and the handset B1, The contents of the phone book data itself such as the name of the other party and the telephone number are not directly exchanged, but basically the necessary processing is performed by exchanging the management number.
[0075]
  FIG. 8 is a sequence diagram illustrating a procedure when a call is made using the child device B1 in another embodiment. As shown in this figure, when the user first performs an operation for browsing the phone book using the handset B1, the handset B1 itself reads out the management number and the name of the other party from the internal management number list, Scroll display on the display unit of the machine B1.
[0076]
  The telephone directory data displayed on the slave unit B1 is selected as a call destination. For example, when the destination name “B” is selected as a call destination, a call request is made from the slave unit B1 to the master unit A. At the same time, the (selection) management number corresponding to the destination name “B” as the call destination is transmitted to the main unit A.
[0077]
  In the main unit A, a telephone number is acquired from the telephone directory data corresponding to the received (selected) management number, and the telephone number is sent to the public telephone line 28 after the line is closed. At this time, a message such as “dialing” is displayed on the slave unit B1, and a call path is formed through a modem or a wireless communication unit (not shown). The subsequent processing is the same as the processing procedure shown in FIG.
[0078]
  In other words, when making a call to the other party using the slave unit B1, it is not necessary to have the phone book data transferred from the master unit A, and the destination name is read from the management number list provided in the slave unit B1 itself. Can be displayed immediately, the scroll display can be smoothed, and the call destination selection operation can be performed quickly.
[0079]
  Further, even when deleting or changing the phone book data of the parent device A, it is not necessary to display the phone book data itself from the parent device A, and use the management number list provided in the child device B1 itself. The data to be deleted or changed can be displayed immediately.

  Next, FIG. 9 is a sequence diagram showing a procedure at the time of an incoming call from the other party in another embodiment. As shown in this figure, when an external line is received from the public telephone line 28, if there is a notification of the caller telephone number, the base unit A compares the caller telephone number with the registered telephone number and matches the registered telephone numbers. In the same way as in the above-described embodiment, the ringing tone is displayed and the other party's name is displayed on the display unit 24. The corresponding management number “002” is read from the telephone directory data, and the management number “002” is transmitted to the slave units B1 to B4 together with the command for calling the outside line. That is, the partner name “B” is not transmitted to the slave devices B1 and B2, but a management number smaller in information amount than the telephone number or the partner name is transmitted.
[0081]
  In each of the slave units B1 and B2 that have received the command for the outside line call and the management number, a ringing sound is generated as in the case of the base unit A, and the other party name corresponding to the received management number is read from the management number list, The name of the other party is displayed on the display unit of the slave unit (not shown).
[0082]
  In this way, when there is a notification of the caller telephone number when an external line is received, a management number with a relatively small amount of information is transmitted from the main unit A to each of the sub units B1 and B2. The destination name can be displayed as quickly as possible.
[0083]
  The present invention is not limited to the above embodiments.
[0084]
  The attribute management table is not essential in the system, and is unnecessary when, for example, the phone book data can be used by all the slave units B1 and B2.
[0085]
  Even in the management number list, all the slave units B1 and B2 may have exactly the same contents.
[0086]
  In addition, when the contents of the phone book data are changed or deleted, it is necessary to change or delete the contents of the management number list including the management number to be changed or deleted. In the case of changing or erasing data, data communication for changing or erasing is performed between the other child device B2 and the parent device A.
[0087]
  Although the data communication amount is basically reduced by exchanging the management number between the main unit A and each of the sub units B1 and B2, in the configuration in which the management number is not added to the phone book data, The name of the other party may be exchanged directly.
[0088]
【The invention's effect】
  As described above, according to the parent-child phone system of the invention described in claim 1, the parent device centrally manages the phone book data, and the child devicesoIs phone book dataControl number list that is part ofRememberKunoThus, the entire system can be configured at a low cost.In addition, when operating the slave unit to make a call to the other party, telephone directory data is not directly exchanged between the master unit and the slave unit, but the management number of the call destination is simply transferred from the slave unit to the master unit. By simply telling, you can have the necessary processing to make a call to the parent machine.
[0089]
  Further, according to the parent-child phone system of the invention described in claim 2, in addition to the effect of the parent-child phone system described in claim 1, the phone book data centrally managed by the parent device,ErasingCan be done.
[0090]
  Furthermore, according to the parent-child phone system of the invention described in claim 3, in addition to the effect by the parent-child phone system according to claim 1 or 2,Change the phone book data centrally managed by the master unit from the slave unitbe able to.
[0091]
[0092]
[0093]
  Claims4According to the parent-child telephone system of the invention described in claim1 to 3In addition to the effects of the parent / child phone system described in, when the main phone receives a caller's phone number notification when an incoming call is received via the telephone line, the phone book data is not exchanged directly between the main phone and the child phone. For example, it is possible to display the telephone number of the caller and the destination information on the slave unit simply by transmitting the management number from the master unit to the slave unit.
