The present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a button telephone apparatus according to the present invention. The key telephone apparatus includes a main apparatus 10 and key telephones (hereinafter referred to as slave units) 20A to 20N accommodated in the main apparatus 10, and the main apparatus 10 accommodates external lines 11a to 11m which are a plurality of ISDN lines. The outer line group 11 including these outer lines 11 a to 11 m is connected to the exchange network 1.

The main apparatus 10 includes an external line I / F unit 12 that controls outgoing and incoming calls of the external lines 11a to 11m, an internal line I / F unit 13 that is an interface of the slave units 20A to 20N, a main control unit 14, and a main storage unit 15. And a T switch (time switch) 16 for connecting a call path between the external lines 11a to 11m and the slave units 20A to 20N.
On the other hand, the slave unit 20 includes a transmission I / F unit 21 that performs transmission with the main device 10, a call circuit 22, a slave unit control unit 23, an operation input unit 24 such as a dial key or an outside line key, a display unit 25, and a memory 26. A handset 27, an amplifier 28, a speaker 29, and the like.

  In the button telephone apparatus configured as described above, for example, when the user of the slave unit 20A operates the outside line key of the operation input unit 24 to make an outside line call and operates the dial key to dial the other party number, These pieces of operation information are detected by the slave unit control unit 23 and transmitted to the main apparatus 10 via the transmission I / F unit 21. When the main control unit 14 of the main apparatus 10 receives the operation information of the external line key and the dial key via the extension I / F unit 13, the main control unit 14 sends the operation information to the external line I / F unit 12 and, for example, via the external line 11a. Call to the exchange network 1 side. When the other party's response is notified from the switching network 1 side to such an outside line call, the main control unit 14 controls the T switch 16 to connect the call path between the outside line 11a and the slave unit 20A. Thereby, the outside line outgoing call by the user of the handset 20A is performed.

  On the other hand, when an incoming call arrives from the switching network 1, for example, to the external line 11a, the external line incoming call is detected by the external line I / F unit 12 and notified to the main control unit 14. In this case, the main control unit 14 transmits the incoming data via the extension I / F unit 13 to the corresponding slave unit 20A. When the incoming call arrives, the main control unit 14 acquires the caller telephone number notified from the exchange network 1 and transmits it to the corresponding handset 20A. In the handset 20A, when the caller telephone number and the incoming data from the main apparatus 1 are received by the transmission I / F unit 21A, they are transmitted to the handset controller 23. When receiving the caller telephone number, the handset controller 23 displays the caller telephone number on the display unit 25. When receiving the incoming data, the handset controller 23 controls the amplifier 28 to perform an incoming ringing process in which a ringtone is transmitted from the speaker 29.

  When the user of the slave unit 20A goes off-hook by raising the handset 27 in order to recognize the incoming ringing and respond to the incoming call, hook switch information based on this off-hook is sent from the operation input unit 24 to the slave unit control unit 23. It is transmitted and detected by the handset controller 23. In this case, handset controller 23 causes transmission I / F unit 21 to transmit off-hook information to main device 10. When the main control unit 14 of the main apparatus 10 receives the off-hook information via the extension I / F unit 13, the main control unit 14 performs incoming call response control on the outer line I / F unit 12, and controls the T switch 16 to control the outer line 11a. The call path between the slave units 20A is connected. Thereby, the outside line incoming call is performed by the user of the slave unit 20A.

  In the button telephone apparatus configured as described above, as shown in FIG. 2, a telephone directory area 15A1, a one-touch dial area 15A2, an outgoing call are stored in the main storage unit 15 of the main apparatus 10 for each of the slave units 20A to 20N. Each area such as a history information recording area 15A3 and an incoming call history information recording area 15A4 is provided. The main storage unit 15 is also provided with a telephone directory area 15B common to each slave unit.

  For this reason, each user of each of the slave units 20A to 20N can create a personal phone book and register and use it in his / her phone book area 15A1. Further, the other party's telephone number and the name of the other party can be registered and used in the one-touch dial area 15A2. When a call is made using a personal phone book registered in the phone book area 15A1 or a personal one-touch dial registered in the one-touch dial area 15A2, the call history information record of the individual is recorded in the same manner as a normal dial operation. It is recorded as a call history in area 15A3. Similarly, when a call is made using a phone book registered in the common phone book area 15C, it is recorded as a call history in the individual call history information recording area 15A3. In the incoming call history information recording area 15A4, incoming calls addressed to the individual are recorded as incoming call history.

  As described above, each of the slave units 20A to 20N is assigned with the telephone directory area 15A1, the one-touch dial area 15A2, the outgoing call history information recording area 15A3, and the incoming call history information recording area 15A4, and is registered or recorded in these areas. Each user's information (personal information of each user) can be viewed only from the corresponding slave 20 by performing a predetermined operation on the corresponding slave 20. However, when a person other than the original user of the child device 20 performs a predetermined operation on the child device 20, there is a problem that even a third party other than the original user can view the child device. Since the privacy of the original user of the device 20 cannot be protected, the telephone book area 15A1, the one-touch dial area 15A2, and the outgoing call history information recording area 15A3 in which personal information of the original user of the child device 20 is registered or recorded. As shown in FIG. 2, the incoming call history information recording area 15A4 is set as a protection target information recording area 15A so that information in these areas can be protected.

  Further, each information of the telephone directory area 15A1, the one-touch dial area 15A2, the outgoing call history information recording area 15A3 and the incoming call history information recording area 15A4 is individually and as shown in the protection table 15C of FIG. Whether to protect each of the slave units 20A to 20N can be set.

  FIG. 3 shows the individual information of each user of each of the slave units 20A to 20N, such as the phone book area 15A1, the one-touch dial area 15A2, the outgoing call history information recording area 15A3, and the incoming call history information recording area 15A4. It is a flowchart which shows operation | movement of the key telephone apparatus set as protection object information which blocks | interrupts browsing (protection) from. The operation of the main part of the present invention will be described according to this flowchart.

  For example, the user of the slave unit 20A selects a menu by performing a predetermined operation of the slave unit 20A (step S1), and selects password management in the menu screen displayed on the display unit 25 (step S2). YES), “password registration / change”, “selection of protection target menu”, and “phone function setting / change” corresponding to this “password management” are displayed on the display unit 25. Here, when the user selects “registration / change of password”, a “password registration / change screen” is displayed on the display unit 25 (step S3), and when “selection of protection target menu” is selected, the screen is displayed. The “protection menu selection (protection / protection release) screen” is displayed on the unit 25 (step S4). When “phone function setting / change” is selected, the display unit 25 displays “phone function setting / change”. Screen "is displayed. Note that such a selection operation in the slave unit 20A is performed by operating a cursor key or a determination key provided in the operation input unit 24 of the slave unit 20A. These operation data are sent to the main device 10 side, and the main device 10 side sends screen display data corresponding to these operation data to the child device 20A side so as to be displayed on the display unit 25. The same applies to the following.

  When the user sets his / her personal information as protection target information, first, the user selects “password registration / change” to display the “password registration / change screen” on the display unit 25 (step S3). Next, “password registration” is selected on this screen (YES in step S6), and the “password registration screen” is displayed on the display unit 25. Then, on this “password registration screen”, a password is entered using a dial key or the like and displayed on the display unit 25 for confirmation (YES in step S7). When pressed (YES in step S8), the password set in step S7 is registered in the area corresponding to the slave 20A in the main storage unit 15 of the main device 10 (step S9).

  After the password is registered in this manner, the user of the slave unit 20A selects “selection of protection target menu” and causes the display unit 25 to display a “selection of protection target menu (protection / protection release) screen” (step S4). On the screen, a password is input using a dial key (YES in step S10). After the input device confirms that the entered password matches the registered password, the user further confirms that “ When “Protect menu to be protected” is selected (YES in step S11), list display data of the menu to be protected is sent from the main device 10 to the slave unit 20A and displayed on the display unit 25 (step S12).

  This protection target menu list data includes the above-mentioned phone book information, outgoing call history information, incoming call history information, one-touch dial information, etc., which are personal information of the user of this handset 20A, and any one of these personal information Can be individually set as protection target information, or all of these individual information (ALL) can be set as protection target information. The user of the slave unit 20A selects the protection target information that protects the browsing by others from the personal information of the slave unit 20A (YES in step S13). This selection information is sent to the main device 10 side, and display data corresponding to this selection information (for example, white display data different from normal display data) is returned to the slave device 20A side. Thus, the selected personal information to be protected is displayed on the display unit 25 of the child device 20A so as to be distinguishable from the personal information to be unprotected (step S14). When the user confirms the display on the display unit 25 and presses the enter key (YES in step S15), the selected personal information to be protected is sent to the main device 10, and the main control unit of the main device 10 is selected. 14 sets “1” in the protection bit corresponding to the personal information selected as the protection target information of the corresponding handset 20A in the protection table 15C in the main storage unit 15 (step S16).

  Thus, the personal information set as the protection target information is not only prevented from being viewed by a third party other than the user of the handset 20A, but is also prevented from being viewed by the original user of the handset 20A. The

  When using the user's own child device 20, the user of the child device 20 </ b> A uses the personal information set as protection target information after canceling the protection. That is, for example, the user of the slave unit 20A uses the slave unit 20A by entering his or her password at the time of attendance to make the setting of the protection target information invalid. In this mode, the personal information of the user of the slave unit 20A can be browsed. That is, “select protection menu” is selected on the handset 20A, and the “protection menu selection (protection / protection release) screen” is displayed on the display unit 25 (step S4). After inputting the password using the key (YES in step S10) and further selecting “protection protection menu protection release” (YES in step S17), the main control unit 14 of the main device 10 receives this selection information. If the input password matches the registered password, a mode is set for invalidating the setting of the protection target information of the corresponding slave unit 20A in the protection table 15C in the main storage unit 15 (step S18).

  If the slave unit 20A is not operated (used) for a predetermined time, the main control unit 14 of the main device 10 determines that the user of the slave unit 20A has left the company and cancels the mode setting. Alternatively, the main control unit 14 detects and cancels the operation of a specific key in the operation input unit 24 of the child device 20A. Then, after this mode is canceled, an operation according to the setting of the protection table 15C is performed.

Next, FIGS. 4 and 5 are sequence diagrams showing the operation of the key telephone apparatus when the personal information of the user of the handset 20 is set as the protection target information. The operation of the main part of the present invention will be described with reference to this sequence diagram. First, the operation described in the sequence diagram of FIG. 4 will be described.
When the password is input in the slave unit 20A as described above (step S31), the input password is sent to the main device 10, and the password in which the input password is registered in the main control unit 14 of the main device 10. Is confirmed (step S32). Then, when the match between the input password and the registered password is confirmed, the setting of the browsing protection target information (protection target information for blocking browsing by others) shown in subsequent steps S33 to S36 is permitted.

  That is, after it is confirmed that the password entered in the slave unit 20A matches the registered password, the browsing protection target information is selected in the slave unit 20A (step S33), and the selection key is pressed (step S34). The protected information is sent to the main device 10 (step S35), and the main control unit 14 of the main device 10 sets the protection bit corresponding to the selected protection target information of the corresponding child device 20A in the protection table 15C to “1”. (Step S36). Thereby, thereafter, the protection target information cannot be browsed by a third party other than the user of the slave unit 20A. In addition, browsing by the original user of the handset 20A becomes impossible.

  Here, when a third party other than the user of the slave unit 20A operates a telephone book key or one-touch key provided in the operation input unit 24 of the slave unit 20 (step S37), the operation information is stored in the main device. 10 is sent. In this case, the main control unit 14 of the main apparatus 10 determines whether the phone book information or the one-touch dial information corresponding to the corresponding child device 20A in the protection table 15C is set as the protection target information, and the protection target information ( In the case of the protection bit “1”), display data “data is protected” is transmitted to the slave unit 20A and displayed on the display unit 25 of the slave unit 20A (steps S38 and S39). ).

  In this way, a third party other than the user of the slave unit 20A operates the phone book key or one-touch key of the slave unit 20 to display the phone book information or one-touch dial information of the slave unit 20A on the display unit 25. After that, even if the display is confirmed and the phone book transmission or the one-touch dial transmission is performed, if the information is the information to be protected, the display data indicating that the data is protected is displayed on the display unit 25. Therefore, it is possible to prevent the browsing and transmission of the phone book information or one-touch dial information registered in the handset 20A. In this case, browsing and transmission by the original user of the handset 20A are also disabled.

  Next, when a third party other than the user of the slave unit 20A operates the operation input unit 24 of the slave unit 20, a request for browsing the transmission history information recorded corresponding to the slave unit 20A is made. (Step S40), the browsing request information is sent to the main device 10. In this case, the main control unit 14 of the main apparatus 10 determines whether or not the outgoing history information corresponding to the corresponding child device 20A in the protection table 15C is the protection target information. Display data indicating that “is protected” is transmitted to the slave unit 20A and displayed on the display unit 25 of the slave unit 20A (steps S41 and S42). As described above, even if a third party other than the user of the slave unit 20A operates the slave unit 20 to make a request for browsing the transmission history information recorded corresponding to the slave unit 20A, Browsing is blocked. In this case, browsing by the original user of the slave 20A is also impossible.

  Next, a third party other than the user of the handset 20A operates the operation input unit 24 of the handset 20, thereby requesting browsing of the received call history information recorded corresponding to the handset 20A. (Step S43), the browsing request information is sent to the main device 10. In this case, the main control unit 14 of the main apparatus 10 determines whether or not the incoming history information corresponding to the corresponding child device 20A in the protection table 15C is the protection target information. Display data indicating that “is protected” is transmitted to the slave unit 20A and displayed on the display unit 25 of the slave unit 20A (steps S44 and S45). As described above, even if a third party other than the user of the slave unit 20A operates the slave unit 20 and requests to browse the incoming call history information recorded corresponding to the slave unit 20A, the browsing is blocked. The In this case, browsing by the original user of the slave 20A is also impossible.

  Further, when, for example, incoming call history information, which is personal information of the user of the slave unit 20A, is set as protection target information, when an incoming call to the slave unit 20A arrives from the switching network 1 (FIG. 5). In step S51), the main control unit 14 of the main device 10 determines that the incoming call is for the user of the slave 20A, acquires the telephone number of the caller who has made an incoming call, the acquired telephone number, and the telephone If a name corresponding to the number is registered in the telephone directory or the like, the name is recorded as incoming history information in the incoming history information recording area 15A4 corresponding to the handset 20A in the main storage unit 15 (step S52). ). Then, a call is made to the corresponding child device 20A (step S53). Here, when the handset 20A side responds to the call (step S54), an incoming call answering call is performed by the user of the handset 20A (step S55). Thus, even if the incoming history information in the incoming call history information recording area 15A4, which is personal information of the user of the slave unit 20A, is set as the protection target information, the incoming history of the incoming call to the user of the slave unit 20A Incoming record history information is recorded in the information recording area 15A4.

  On the other hand, when, for example, transmission history information, which is personal information of the user of the child device 20A, is set as protection target information, an outside line transmission operation based on the operation of the operation input unit 24 of the child device 20A is performed (step S56), this operation information is sent to the main apparatus 10. In this case, the main control unit 14 of the main device 10 determines that this outside line transmission may have been transmitted by a third party other than the original user of the handset 20A, and the dial number based on this outside line transmission operation. Is not recorded in the transmission history information recording area 15A3 corresponding to the slave unit 20 as transmission history information (step S57), and the outside line transmission process is performed to send the dial number operated on the slave unit 20A to the outside line as a dial signal. This is performed (step S58).

  When the user of the slave unit 20A or another person presses the common phone book key provided in the operation input unit 24 of the slave unit 20A (step S59), this operation information is sent to the main device 10, and in this case The main control unit 14 of the main apparatus 10 sends the registration information of the common phone book area 15B to the slave 20A for display because the common phone book area 15B in the main storage unit 15 does not correspond to the protection target information recording area. The data is displayed on the unit 25 (step S60). Here, when a call destination is specified from the common phone book information displayed on the display unit 25 on the handset 20A side and a call operation is performed (step S61), the operation information is sent to the main device 10, In this case, the main control unit 14 of the main apparatus 10 performs an outside line transmission to the designated transmission destination (step S62).

  In this embodiment, the protection target information is set by inputting the password from the slave unit 20 and authenticating the user of the slave unit 20 based on the match between the entered password and the registered password. However, by holding the IC card in which the employee number is stored over the handset 20, the employee number is entered and the user's identity is verified based on the match between the entered employee number and the registered employee number. It is also possible to detect a fingerprint by a fingerprint sensor provided in the slave unit 20 and substitute it by authenticating the user based on a match between the detected fingerprint information and registered fingerprint information.
