The extension telephone is
Memo generating means for generating handwritten memo data based on the input coordinate information;
Telephone side memo transmission means for transmitting the handwritten memo data generated by the memo generation means to the main device;
Telephone side memo receiving means for receiving handwritten memo data from the main device;
Memo output means for outputting the handwritten memo data received by the telephone side memo receiving means.

  According to the present invention, the above configuration can provide a technique for generating and transferring handwritten memo data without using memo paper.

  Embodiments of the present invention will be described below.

  FIG. 1 is a schematic diagram of an extension telephone system to which an embodiment of the present invention is applied.

  As shown in the figure, the extension telephone system of the present embodiment includes a main apparatus 1 that accommodates at least one outer line 3 and a plurality of extensions 4, and an extension telephone 2 that is connected to each of the plurality of extensions 4.

  The main device 1 has a function of storing and transferring handwritten memo data (image data) in addition to general functions such as dial-in, representative (group) reception, and proxy response. FIG. 2 is a schematic block diagram of the main device 1.

  As shown in the figure, the main device 1 includes an external line IF (interface) unit 11, an internal line IF unit 12, a station data storage unit 13, a handwritten memo data storage unit 14, a handwritten memo data processing unit 15, and communication control. Unit 16 and main control unit 17.

  The external line IF unit 11 is a physical interface for connecting the main apparatus 1 to at least one external line 3.

  The extension IF unit 12 is a physical interface for connecting the main apparatus 1 to a plurality of extensions 4.

  The station data storage unit 13 stores station data indicating the correspondence between the telephone number and the extension 4. FIG. 3 is a diagram schematically showing registration contents (station data) in the station data storage unit 13.

  As shown in the figure, a record 130 is registered in the station data storage unit 13 for each telephone (external line) number. The record 130 includes a field 1301 for registering a telephone number, a field 1302 for registering the number type (one of representative number, group number, and dial-in number) of the telephone number, and an extension assigned to the telephone number. And a field 1303 for registering a number.

  When “representative number” is registered as the number type in the field 1302 of the record 130, the extension numbers of all the extensions 4 accommodated in the main device 1 are included in the telephone numbers registered in the field 1301 of the record 130. Assigned. In this case, in the present embodiment, the extension numbers of all the extensions 4 are registered in the field 1303 of the record 130, but this is not necessarily required. For example, this field 1303 may be Null. Further, when “group number” is registered as the number type in the field 1302 of the record 130, the telephone number registered in the field 1301 of this record 130 includes the extension 4 accommodated by the main apparatus 1. The extension numbers of all the extensions 4 belonging to the group specified by the telephone number are assigned. When “dial-in number” is registered as the number type in the field 1302 of the record 130, the telephone number registered in the field 1301 of the record 130 includes the extension 4 accommodated by the main device 1. One extension number is assigned.

  The handwritten memo data storage unit 14 stores handwritten memo data. FIG. 4 is a diagram schematically showing the registered contents of the handwritten memo data storage unit 14.

  As illustrated, a record 140 is registered in the handwritten memo data storage unit 14 for each handwritten memo data. The record 140 registers a field 1401 for registering handwritten memo data (image data) and the extension number (creating source extension number) of the extension 4 to which the extension telephone 2 that has created (transmitted) the handwritten memo data is connected. The field 1402, the field 1403 for registering the extension number (transfer destination extension number) of the extension 4 to which the handwritten memo data is to be transferred, and the message that is the source of the handwritten memo data are left in the creator of the handwritten memo data A field 1404 for registering the telephone number (caller external line number) of the person (caller of the handwritten memo data creator), and a field 1405 for registering the creation date and time of the handwritten memo data.

  When the incoming number of the call is a dial-in number, the extension number of the extension 4 connected to the extension telephone 2 that has made a proxy response is registered in the field 1402, and the field 1403 is assigned to this dial-in number. The extension number of extension 4 is registered. When the called party number is a representative number, the extension number of the extension 4 connected to the extension telephone 2 that has made a representative response is registered in the field 1402, and the extension telephone number 2 connected to the representative answering extension telephone 2 is registered in the field 1403. The extension numbers of all the extensions 4 other than the extension 4 being registered are registered. When the called party number is a group number, the extension number of the extension 4 connected to the extension telephone 2 that has made a proxy or representative response is registered in the field 1402, and the field 1403 indicates this for a proxy response. The extension numbers of all the extensions 4 assigned to the group number are registered, and in the case of a representative response, the extensions 4 connected to the extension telephone 2 that has made a representative response out of the extensions 4 assigned to this group number are excluded. The extension number 2 of all the extensions 4 is registered.

  Here, the representative response means a response that the extension telephone 2 connected to one of these extensions 4 makes in response to this call when a call is sent to a plurality of extensions 4. The proxy response means a response that the extension telephone 2 connected to the extension 4 other than the extension 4 to which the call is sent performs in response to this call. In the following description, the normal response means a response that the extension telephone 2 connected to the extension 4 makes in response to the call when a call is sent to one extension 4.

  The handwritten memo data processing unit 15 reads the handwritten memo data from the handwritten memo data storage unit 14 according to the instruction of the main control unit 17, and encodes the handwritten memo data according to an encoding method such as MH, MR, MMR, JBIG. A facsimile signal is generated, and the generated facsimile signal is output to the communication control unit 16. Further, the facsimile signal input from the communication control unit 16 is decoded according to an encoding method such as MH, MR, MMR, JBIG, etc. to restore the handwritten memo data, and the restored handwritten memo data is stored in the handwritten memo data storage unit 14. Remember.

  The communication control unit 16 controls connection (relay) among the external line IF unit 11, the internal line IF unit 12, and the handwritten memo data processing unit 15 in accordance with an instruction from the main control unit 17.

  And the main control part 17 controls each part 11-16 of the main apparatus 1 centralizedly.

  FIG. 5 is a flowchart for explaining the operation of the main apparatus 1.

  When the communication control unit 16 receives a memo request message from any of the extensions 4 via the extension IF unit 12 (YES in S101), the communication control unit 16 sends the memo request together with the extension number assigned to the extension 4 to the main control unit. 17 is notified. In response, the main control unit 17 performs a memo transfer process described later (S102), and returns to S101. For example, a predetermined PB (push button) signal or a PB signal string can be used for the memo request message.

  Further, when a call arrives from the external line 3 to the external line IF unit 11 (YES in S103), the communication control unit 16 notifies the main control unit 17 of this call. In response to this, the main control unit 17 refers to the station data storage unit 13 and specifies the extension number associated with the called number (telephone (external line) number) of this call. Then, the specified extension number is temporarily stored in a memory or the like (not shown) together with the call origination number (S104). Then, main controller 17 makes a primary response to this call (S105), and waits for a memo request message sent from the other party during a predetermined period, for example (S106).

  If the main control unit 17 receives a memo request message from the other party (YES in S106), the main control unit 17 performs a memo transfer process described later (S102), and returns to S101. On the other hand, if the memo request message has not been received (No in S106), the process proceeds to S107.

  In S107, the main control unit 17 controls the communication control unit 16, and sends a call message to the extension 4 corresponding to the extension number stored in S104. If a response message to the call message is received from any extension 4 (YES in S108), the communication control unit 16 is controlled to connect the call that has been primarily answered in S105 to this extension 4 (S109). . As a result, a call is started between the extension telephone 2 connected to the extension 4 and the caller terminal of the call that made the primary response in S105. At this time, the main control unit 17 temporarily stores the response message type (any one of the normal response, the representative response, and the proxy response) in a memory or the like (not shown).

  When the communication control unit 16 receives a disconnection request message from the external line 3 through the external line IF unit 11 or from the internal line 4 through the internal line IF unit 12 regarding the connected call (S110), the communication control unit 16 issues a disconnection request. Notify the main control unit 17. In response, the main control unit 17 controls the communication control unit 16 to disconnect the call requested to be disconnected (S111).

  Next, the main control unit 17 checks the type of the response message stored in S109 (S112). When the type of the response message is “normal response” (NO in S112), the process returns to S101. On the other hand, when the type of the response message is “representative response” or “proxy response” (YES in S112), a memo accumulation process described later is performed (S113), and then the process returns to S101.

  FIG. 6 is a flowchart for explaining the memo accumulation process (S113 in FIG. 5).

  First, the main control unit 17 determines whether or not handwritten memo data is created by the extension telephone 2 connected to the extension 4 that is the relay destination of the call disconnected in S111 of FIG. 5 (S1131). This may be determined based on, for example, whether a message indicating “there is handwritten memo data” or “handwritten memo data” itself is sent within a predetermined time from the extension 4 of the relayed call destination. If handwritten memo data is not created (No in S1131), this flow is terminated. On the other hand, when handwritten memo data is created (YES in S1131), the main control unit 17 controls the communication control unit 16 to send from the extension 4 that is the relay destination of the disconnected call via the extension IF unit 12. The received facsimile signal is input to the handwritten memo data processing unit 15. In response to this, the handwritten memo data processing unit 15 decodes the facsimile signal input from the communication control unit 16 to restore the handwritten memo data. Thereby, the handwritten memo data is received from the extension 4 of the relay destination of the disconnected call.

  If handwritten memo data is received from the extension 4 of the call relay destination disconnected in S111 in FIG. 5 (YES in S1132), the main control unit 17 displays the extension number assigned to the extension 4. 5 is excluded from the extension number stored in S104, and the extension number of the transfer destination of the handwritten memo data is specified (S1133). When the transmission source of the handwritten memo data is a proxy response, the extension number of the extension 4 to which the transmission source of the handwritten memo data is connected is not included in the extension number stored in S104 of FIG. Accordingly, all the extension numbers stored in S104 of FIG. 5 are specified as the transfer destination extension numbers. On the other hand, when the transmission source of the handwritten memo data is a representative response, the extension number of the extension 4 to which the transmission source of the handwritten memo data is connected is included in the extension number stored in S104 of FIG. Therefore, all the extension numbers stored in S104 of FIG. 5 except the extension number of the extension 4 to which the transmission source of the handwritten memo data is connected are specified as the transfer destination extension numbers.

  Next, the main control unit 17 determines the transfer destination extension number specified as described above, the extension number of the extension 4 to which the transmission source of the handwritten memo data is connected (creating source extension number), and S104 in FIG. Is output to the handwritten memo data processing unit 15 together with the calling number (caller outside line number) stored in step S2. In response to this, the handwritten memo data processing unit 15 adds a new record 140 to the handwritten memo data storage unit 14. Then, the handwritten memo data is shown in the field 1401 of the added record 140, the source extension number in the field 1402, the transfer destination extension number in the field 1403, the source extension number in the field 1404, and the field 1405. The current date and time acquired by using a timer that has not been registered is registered (S1134).

  Thereafter, the main control unit 17 controls the communication control unit 16 to transmit a message indicating the presence of handwritten memo data to each extension 4 to which the transfer destination extension number specified in S1133 is assigned (S1135). End the flow.

  FIG. 7 is a flowchart for explaining the memo transfer process (S102 in FIG. 5).

  First, the main control unit 17 determines whether the transmission source of the memo request message is the extension 4 side (in the case of YES in S101 in FIG. 5) or the external line 3 side (in the case of YES in S106 in FIG. 5). Judgment is made (S1021). In the case of the extension 4 side, the process proceeds to S1022, and in the case of the external line 3 side, the process proceeds to S1026.

  In step S1022, the main control unit 17 notifies the handwritten memo data processing unit 15 of the extension number of the extension 4 to which the transmission source of the memo request message is connected, and instructs transmission of the handwritten memo data. In response to this, the handwritten memo data processing unit 15 searches the handwritten memo data storage unit 14 for the record 140 having the extension number notified from the main control unit 17 as the transfer destination extension number. Then, additional information (image data) including the created extension number registered in the retrieved record 140, the calling source external number, and the created date and time is generated (S1023), and this additional information is registered in the retrieved record 140. It is synthesized (merged) with the handwritten memo data (S1024).

  Then, the handwritten memo data processing unit 15 encodes the handwritten memo data combined with the additional information to generate a facsimile signal, and the facsimile signal is transmitted to the memo request message via the communication control unit 16 and the extension IF unit 12. To the extension 4 to which the transmission source is connected (S1025). Thereafter, this flow is terminated.

  On the other hand, in S1026, the main control unit 17 controls the communication control unit 16 to accept an extension number and a password (PW) from the transmission source of the memo request message. Then, the main control unit 17 performs an authentication process by checking whether or not the accepted password matches authentication information registered in advance in a memory (not shown) or the like (S1027). Here, the authentication information may be provided for each extension number.

  If authentication is successful (YES in S1028), the process proceeds to S1029. On the other hand, if authentication is not established (NO in S1028), the main control unit 17 controls the communication control unit 16 to perform predetermined error processing such as transmitting an error message to the transmission source of the memo request message (S1033), This flow is finished.

  In step S1029, the main control unit 17 transmits to the handwritten memo data processing unit 15 the outside line number of the transmission source of the memo request message (the caller number of the call that was primarily responded in step S105 in FIG. 5), and the transmission of the memo request message in step S1026. The extension number received from the source is notified and transmission of handwritten memo data is instructed. In response to this, the handwritten memo data processing unit 15 searches the handwritten memo data storage unit 14 for the record 140 having the extension number notified from the main control unit 17 as the transfer destination extension number. Then, additional information (image data) including the created extension number registered in the retrieved record 140, the sender's external number, and the created date / time is generated (S1030), and this additional information is registered in the retrieved record 140. It is synthesized (merged) with the handwritten memo data (S1031).

  Then, the handwritten memo data processing unit 15 encodes the handwritten memo data combined with the additional information to generate a facsimile signal, and this facsimile signal is sent to the memo request message via the communication control unit 16 and the external line IF unit 11. To the outside line number of the transmission source (source of the call that made the primary response in S105 of FIG. 5) (S1032). Thereafter, this flow is terminated.

  Returning to FIG. 1, the description will be continued. The extension telephone 2 has a function of creating and transmitting / receiving handwritten memo data (image data) in addition to general functions such as representative response and proxy response. FIG. 8 is a schematic block diagram of the extension telephone 2.

  As shown, the extension telephone 2 includes an extension IF unit 21, an operation panel 22, a handset 23, a tablet 24 with a display function, a voice processing unit 25, a handwritten memo data processing unit 26, and a main control unit 27. And having.

  The extension IF unit 21 is a physical interface for connecting the extension telephone 2 to the extension 4.

  The operation panel 22 includes an input unit 221 such as buttons and keys, and an output unit 222 such as a liquid crystal panel, LED, and speaker. The operation panel 22 transmits an instruction received from the operator via the input unit 221 to the main control unit 27. The information received from the main control unit 27 is output from the output unit 222.

  The handset 23 includes a microphone 231 and a speaker 232. The handset 23 transmits the audio signal collected by the microphone 231 to the main control unit 27. The audio signal received from the main control unit 27 is output as audio from the speaker 232.

  The tablet 24 with a display function includes an input unit 241 including a data tablet and a display unit 242 such as a liquid crystal panel. The tablet 24 with a display function transmits coordinate information indicating the locus of the touch pen 243 (operator's memo writing) on the input unit (data tablet) 241 to the handwritten memo data processing unit 26. The handwritten memo data received from the handwritten memo data processing unit 26 is displayed on the display unit 242. Note that the tablet 24 with a display function may be built in the extension telephone 2 or may be of a so-called external type.

  The voice processing unit 25 converts the voice signal received from the handset 23 into a telephone call signal and transmits it to the main control unit 27. Also, the call signal received from the main control unit 27 is converted into a voice signal and output to the handset 23.

  The main control unit 27 comprehensively controls each unit 21 to 26 of the extension telephone 2.

  FIG. 9 is a flowchart for explaining the operation of the extension telephone 2.

  When the main control unit 27 receives a call message from the main apparatus 1 via the extension IF unit 21 (YES in S201), the main control unit 27 outputs a ringing tone from the output unit 222 (S202). If a response instruction (for example, off-hook operation) is received from the operator (YES in S203), the process proceeds to S204. Further, when receiving a proxy response instruction (for example, a combination of a predetermined key operation and an off-hook operation) from the operator (S209), the main control unit 27 proceeds to S204.

  In S <b> 204, the main control unit 27 connects the voice processing unit 25 to the extension IF unit 21. Thereby, the audio signal collected by the microphone 231 is converted into a call signal by the audio processing unit 25 and transmitted to the main apparatus 1. In addition, the call signal received from the main device 1 is converted into an audio signal by the audio processing unit 25 and output from the speaker 232 as audio. In this way, a call is started.

  When the call is started, the main control unit 27 controls the handwritten memo data processing unit 26 to start receiving coordinate information (trajectory information of the touch pen 243) input to the input unit 241 (S205). When a proxy response instruction is accepted (YES in S209) or when the response instruction accepted in S203 is a representative response, a note writing start instruction (for example, a predetermined key operation) is accepted from the operator. Only in this case, reception of coordinate information may be started. Here, whether or not the response instruction received in S203 is a representative response indicates, for example, the type of incoming call from the external line 3 (representative incoming call, group incoming call, dial-in incoming call) in the call message sent by the main device 1 The type information may be added and the main control unit 27 may make a determination based on the type information included in the call message.

  Next, when the main control unit 27 receives a disconnection instruction (for example, an on-hook operation) from the operator, that is, when the call ends (YES in S206), is the handwritten memo data processing unit 26 receiving the trajectory information of the touch pen 243? It is determined whether or not (S207).

  If no trajectory information has been received (NO in S207), the process returns to S201. On the other hand, when the trajectory information is received (YES in S207), the main control unit 27 waits for reception of a memo transmission instruction (for example, a predetermined key operation) from the operator for a predetermined period, and then the handwritten memo data processing unit 26. To send a memo. In response to this, the handwritten memo data processing unit 26 generates handwritten memo data based on the received trajectory information, and encodes it to generate a facsimile signal. The main control unit 27 transmits this facsimile signal to the main apparatus 1 via the extension IF unit 21 (S208). Thereafter, the process returns to S201. Prior to the transmission of the facsimile signal, the main control unit 27 may transmit a message indicating “there is handwritten memo data” to the main apparatus 1.

  Further, when the main control unit 27 receives a message indicating the presence of handwritten memo data from the main apparatus 1 via the extension IF unit 21 (YES in S210), the main control unit 27 turns on a predetermined LED or displays that on the liquid crystal panel. Is displayed on the output unit 222 (S211). Thereafter, the process returns to S201.

  When the main control unit 27 receives a memo request instruction from the operator via the input unit 221 (YES in S212), the main control unit 27 generates a memo request message and requests the memo request from the main device 1 via the extension IF unit 21. A message is transmitted (S213), and it waits for a facsimile signal to be sent from the main apparatus 1. If a facsimile signal is received, it is output to the handwritten memo data processing unit 26. In response to this, the handwritten memo data processing unit 26 decodes the facsimile signal received from the main control unit 27 to restore the handwritten memo data, and displays it on the display unit 242 (S214). Thereafter, the process returns to S201.

  Next, the overall operation of the extension telephone system configured as described above will be described.

  FIG. 10 is a sequence diagram for explaining the overall operation of the extension telephone system when any extension telephone 2 makes a proxy response.

  When the main apparatus 1 receives a call from the external line terminal 5 (S301), the main apparatus 1 transmits a call message to the extension telephone 2A having the extension number corresponding to the called number (S302). If the called number is a dial-in number, a call message is transmitted to one extension telephone 2A corresponding to this dial-in number, and if it is a group number, a call message is transmitted to a plurality of extension telephones 2A corresponding to this group number. The In response to this, the extension telephone 2A outputs a ringing tone.

  Here, the extension telephone that does not output the ringing tone (the extension telephone having an extension number that does not correspond to the called number) 2B receives a proxy response instruction from the operator, and transmits a proxy response message to the main apparatus 1. (S303). In response to this, the main apparatus 1 relays the call received from the external terminal 5 to the extension telephone 2B. Thereby, a telephone call is started between the outside line terminal 5 and the extension telephone 2B (S304). Further, the extension telephone 2B starts accepting memos from the operator (S305).

  When the call ends (S306), the extension telephone 2B generates handwritten memo data based on the memo accepted from the operator (S307) and transmits it to the main device 1 (S308). In response to this, the main device 1 stores the handwritten memo data received from the extension telephone 2B in association with the extension number associated with the called number relayed to the extension telephone 2B (S309). A message with a memo indicating that a memo exists is transmitted to the extension telephone 2A having the extension number associated with the called number of the call relayed to the extension telephone 2B (S310). Receiving this, the extension telephone 2A displays on the display unit 222 that a memo exists, and notifies the operator (S311).

  Next, when the extension telephone 2A receives a memo request instruction from the operator, it transmits a memo request message to the main apparatus 1 (S312). In response to this, the main apparatus 1 transmits the handwritten memo data stored in association with the extension number of the extension telephone 2A to the extension telephone 2A (S313). The extension telephone 2A displays the handwritten memo data received from the main device 1 (S314).

  FIG. 11 is a sequence diagram for explaining the overall operation of the extension telephone system when one of the extension telephones 2 makes a representative response.

When the main device 1 receives a call from the external line terminal 5 (S401), it transmits a call message to the extension telephone 2A having the extension number corresponding to the called number (S402). If the called number is a representative number, a call message is transmitted to all the extension telephones 2A _{1 to} 2A _n connected to the main apparatus 1, and if the called number is a group number, a plurality of extension telephones 2A ₁ corresponding to this group number are transmitted. call message is sent to the to 2A region _n. In response to this, the extension telephone _2A 1 to 2A region _n outputs a ringing tone.

Here, when one of the extension telephones 2A _x (2A _{n in} FIG. 11) outputting the ringing tone receives a response instruction from the operator, it transmits a representative response message to the main apparatus 1 (S403). In response to this, the main apparatus 1 relays a call received from outside line terminal 5 to the extension telephone 2A _x. Thus, the call between the external line terminals 5 and the extension telephone 2A _x is started (S404). Further, the extension telephone 2A _x starts accepting a memo from the operator (S405).

Now, the call is terminated (S406), the extension telephone 2A _x generates handwritten memo data based on memo received from the operator (S407), and transmits it to the main unit 1 (S408). In response to this, the main apparatus 1 transmits the handwritten memo data received from the extension telephone 2A _x to the extension of the extension telephone 2A _x out of the extension numbers associated with the called party number relayed to the extension telephone 2A _x . The information is stored in association with all the extension numbers except the number (S409). Also, of the extension number associated with the called number of the call that is relayed to the extension telephone 2A _x, to all extension telephones 2A ₁ to 2A region _n whose extensions except the extension number of the extension telephone 2A _x, notes A message with a memo indicating that it exists is transmitted (S410).
