Description

  The present invention relates to a display information switching device, a display information switching system, a display information switching method, and a display information switching program for switching information to be displayed.

  Fixed telephones connected to analog lines and IP (Internet Protocol) telephones connected to optical fiber lines and ISDN (Integrated Services Digital Network) lines are widely used.

  When a call is received at these telephones, it is common practice to display the telephone number of the caller as a communication partner (hereinafter referred to as “calling number” as appropriate) on the display unit of the telephone. Such a service is called by a name such as a number display.

  It is also common to create a so-called phone book by preliminarily storing information such as the other party's phone number, the other party's name, the other party's name reading and the company or department to which the other party belongs. Has been done.

  If the phone book is created in this way, when there is an incoming call, the phone book is searched using the calling number as a search key, and the other party is the information linked to the same phone number as the calling number Can be displayed on the display unit of the telephone.

  An example of a technique for displaying information on such a telephone is described in Patent Document 1, for example.

  In the technique described in Patent Document 1, a table in which a caller number and a caller name are associated with each other is created in advance. When an incoming call is actually received, the caller name corresponding to the calling number is specified by searching this table.

  Thus, by displaying the specified caller name on the display unit of the telephone, the user can know who the caller is.

It is a figure showing the example of a display in the display part in the 3rd Embodiment of this invention.

  First, an outline of an embodiment of the present invention will be described.

  Embodiments of the present invention relate to a telephone that searches a telephone directory for a caller number (calling number) notified when a call is received and displays the name on a display unit, and changes the displayed name according to the situation. Is.

  If the display of the telephone is large, all stored information such as a telephone number, name 1 (personal name), name 2 (company name, department name, etc.) may be displayed. However, in the case of a small display telephone that cannot display all information, in the present embodiment, name 1 (personal name) is displayed at one time, and name 2 (company name / department) at other times. Name). Moreover, you may make it display a telephone number together with such information.

  The above is the outline of the embodiment of the present invention.

  Next, three embodiments of the first embodiment, the second embodiment, and the third embodiment of the present invention will be described in detail with reference to the drawings.

<First Embodiment>
In the first embodiment, when a call is received to the company representative number or department representative number, the notified calling number is searched in the phone book, the company name and department name are displayed, and a personal number is called by dial-in or the like. When an incoming call is received, the notified calling number is searched in the phone book and the personal name is displayed.

  The reason will be described. In the case of an incoming call to a representative number, the person who receives the incoming call is the person at the reception, so it is not possible to know who is displayed even if the personal name is displayed. For this reason, it is easier to answer the phone if the company name is displayed. On the other hand, in the case of a dial-in incoming call to a person in charge of the sales department etc., it is possible to receive a call according to the caller by displaying with a personal name already known rather than displaying the company name. Because there is, the personal name is displayed.

  Next, the telephone system 10 which is this embodiment is demonstrated with reference to FIG.

  The telephone system 10 includes a plurality of display switching telephones 100, an exchange 200, and a public network 300.

  The display switching telephone 100-1 is installed in a representative department that primarily handles external calls and is assigned a representative number. The display switching telephone 100-1 is used by an operator in the representative department, for example.

  On the other hand, the display switching telephone 100-2 is installed in a sales department that conducts sales activities and is used by employees of the sales department. Similarly, the display switching telephone 100-n is installed in a development department that conducts development activities and is used by employees of the development department. A separate number other than the representative number is assigned to the display switching telephone 100-2 and the display switching telephone 100-n (n is a positive integer). Specifically, for example, a dial-in number that is a telephone number provided by a dial-in service is assigned. Here, the dial-in service is a service that provides a dial-in number that can be additionally used in addition to a telephone number (representative number) assigned to a line contracted with a telephone carrier.

  A technique relating to a dial-in number is described in Patent Document 2, for example. Here, in the technique described in Patent Document 2, the exchange receives a dial-in number from the ISDN network, and if the dial-in number is related to voice communication, calls the terminal corresponding to the dial-in number. It is described that a voice call is realized.

  1 and the following description will be made on the assumption that the display switching telephone 100 is installed for each department. That is, although described in units of departments, the display switching telephone 100 may be installed in other units. For example, it may be a unit of each section included in a department, or a group of some kind of group. In addition, a display switching telephone 100 to which a representative number is assigned for each department may be installed.

  The exchange 200 is connected to each display switching telephone 100 and the public network 300. Then, the exchange 200 connects the incoming call from the external telephone connected to the public network 300 to the corresponding display switching telephone 100 based on the telephone number such as the representative number or the dial-in number as the destination. Thereby, the exchange 200 realizes communication between the telephone connected to the outside line and the display switching telephone 100. The exchange 200 also realizes extension communication between the display switching telephones 100. The exchange 200 notifies the display switching telephone 100 that is the destination of the calling number of the external telephone.

  The public network 300 is a public telephone network. An external telephone connected to the public network 300 communicates with each display switching telephone 100 via the public network 300 and the exchange 200. The public network 300 may be an analog line or a digital line such as an optical line or an ISDN line.

  Next, each functional block included in the display switching telephone 100 will be described with reference to FIG.

  Referring to FIG. 2, the display switching telephone 100 includes a control unit 101, a display unit 102, an information storage unit 103, a communication unit 104, and an input reception unit 105.

  The control unit 101 is a part that controls the entire display switching telephone 100. The control unit 101 is realized by, for example, a combination of an arithmetic processing device such as a CPU (Central Processing Unit) and a storage device such as a ROM (read only memory) or a RAM (Random Access Memory). Then, the CPU reads the software stored in the ROM, performs arithmetic processing while developing it in the RAM, and controls each hardware based on the result of the arithmetic processing, thereby realizing control of the entire display switching telephone 100. . Part or all of the software may be stored in the information storage unit 103 described later. Further, the control unit 101 may be realized by a microcomputer on which a CPU or the like is mounted, for example.

  Under the control of the control unit 101, the display switching telephone 100 performs a voice call with another telephone. Further, switching of display information to be described later is also performed under the control of the control unit 101.

  The display unit 102 is a display unit for displaying information such as a calling number. The display unit 102 is realized by, for example, a liquid crystal display (LCD). The size of the display unit 102 is determined in consideration of the overall size of the display switching telephone 100 and the like. Accordingly, the display unit 102 does not display all information related to the other party who is the other party of the display switching telephone 100. Therefore, in the present embodiment, information corresponding to the situation is displayed by switching display information described later. The information related to the other party is, for example, information such as the other party's telephone number, the other party's name, the other party's name reading, and the company or department to which the other party belongs.

  The information storage unit 103 is a storage unit that stores a telephone directory. Here, the phone book is realized by a table that is displayed on the display unit 102 and includes information related to the other party who is the other party. The phone book may be stored in the information storage unit 103, but a part or all of the phone book may be stored in the control unit 101.

  The communication unit 104 is an interface for connecting to the exchange 200. The display switching telephone 100 communicates with other telephones connected to the outside line and other display switching telephones 100 connected to the extension via the communication unit 104 and the exchange 200.

  The input receiving unit 105 is a part that receives a user operation, and is realized by, for example, a numeric keypad for inputting a telephone number, a hold button for holding a call, and a button for assigning a function such as a speed dial.

  The functional blocks included in the display switching telephone 100 have been described above. However, these are only parts particularly related to display switching in the present embodiment. In addition to the above-described parts, the display switching telephone 100 includes a handset in which a speaker and a microphone are integrated, and a part included in a general telephone such as a power source. However, since the parts included in these general telephones are well known to those skilled in the art, description and illustration are omitted here.

  The general configuration of the exchange 200 is also described in, for example, Patent Document 2 described above, which is also well known to those skilled in the art, and thus description of the functional blocks of the exchange 200 is omitted.

  Next, a specific example of the telephone directory stored in the information storage unit 103 or the control unit 101 will be described with reference to FIG.

  First, referring to FIG. 3, in the telephone directory, a reading, a name, a telephone number 1, a telephone number 2, and a group are registered in association with each other.

  First, looking at the top row, “Furigana: Adachi, Name: Adachi, Phone number 1: 5656, Phone number 2: 3248, Group: 2” are registered. This is an association of an individual name, a group corresponding to the individual, and a telephone number used by the individual.

  Similarly, personal names up to “Taro Yamada” are registered in order of Iueo.

  Here, as can be seen from the example in the figure, the personal name may be a combination of a last name and a name, for example, only a last name or only a name.

  In the lower part of FIG. 3, registration with a name other than the personal name is also performed. For example, the phone number “1234” is registered for the reading “Yamada Taro” together with the personal name “Taro Yamada”.

  In addition to this, the phone number “1234” is registered for the reading “Yamada Taro” together with the company name “XX Trading” to which Mr. Yamada Taro belongs. This is information that is used when there is an incoming call for a representative number. To clarify it, a symbol such as * is added in front of the reading and it is registered as “Group: 9”. Yes.

  The control unit 101 executes display switching using such a telephone directory.

  One person may be associated with a plurality of telephone numbers so that there are telephone numbers 1 and 2. For example, both a fixed telephone number used by an individual and a mobile phone number used by the individual may be linked.

  Further, in order to simplify the description in the figure, the number of digits of the telephone number is four digits, but the telephone number may have other digits.

  Furthermore, not only a company name such as “XX Trading” but also other names such as some organization name or department name may be registered.

  Next, with reference to the flowchart of FIG. 4 and FIGS. 5 and 6, a specific operation of the display switching telephone 100 at the time of incoming call will be described. It is assumed that a telephone number such as a representative telephone number or a personal telephone number is assigned to each display switching telephone 100 as a premise for performing processing at the time of incoming call described below.

  First, the control unit 101 checks whether there is an incoming call at a predetermined interval (step S11). If there is no incoming call, the incoming call confirmation is continued (No in step S11).

  When an incoming call is received from any telephone through the exchange 200 (Yes in step S1), the process proceeds to step S12.

  In step S12, it is confirmed whether the call is for a representative number or a personal number such as a dial-in number. That is, it is confirmed whether the telephone number assigned to the display switching telephone 100 is a representative number or a personal number.

  Here, the confirmation can be performed by an arbitrary method. For example, whether the telephone number assigned to the display switching telephone 100 is a representative number or a personal number is set in advance, and the setting contents are stored in the control unit 101 or the information storage unit 103. . And it can confirm by referring the content memorize | stored in step S12.

  In addition, for example, the exchange 200 can also confirm whether the telephone number assigned to the display switching telephone 100 is a representative number or a personal number.

  Here, it is assumed that the telephone number assigned to the display switching telephone 100 is a representative number as a result of the confirmation (Yes in step S12: representative number). In that case, the telephone book is searched by the control unit 101, and the company name (or other name such as some organization name or department name) associated with the telephone number is specified. Then, the specified company name (or some other name such as an organization name or department name) is displayed on the display unit 102 (step S13).

  This point will be described with reference to FIGS. When an incoming call is made to the representative number, a search is performed as described in the upper part of FIG. Specifically, information registered as group 9 is searched preferentially rather than groups registered as groups 1 to 8.

  For example, assume that the current calling number is “1234”. In this case, “1234” is searched for telephone number 1 and telephone number 2 of group 9 as a search key.

  As a result, “Furigana: * Yamada Taro, name: OO trading, telephone number 1: 1234, group: 9” is specified as a search result. The telephone number for this time was registered in group 9. However, if the group 9 is not registered, that is, if only the personal name is registered, the personal name is specified.

  Then, the control unit 101 displays the name “XX Shoji” on the display unit 101 based on the search result. A display example in this case is shown in the upper part of FIG. Referring to the upper part of FIG. 6, the display unit 102 displays a display indicating that a call is being received, a display indicating that the caller is “XX trading”, and a calling number “1234”.

  The user who uses the representative number referring to such a display knows that the incoming call is from a person who belongs to “XX Trading”. And it is possible to respond to the telephone after grasping it.

  Note that the telephone number may not be displayed according to the size of the display unit 101. In addition, a message indicating that a call is being received may be displayed on the screen, or alternatively, for example, an LED (light emitting diode) indicating an incoming call may be blinked or a ring tone may be emitted.

  On the other hand, as a result of the confirmation in step S12, it is assumed that the telephone number assigned to the display switching telephone 100 is a personal number (No in step S12: personal number). In that case, the telephone book is searched by the control unit 101, and the personal name associated with the telephone number is specified. Then, the identified personal name is displayed on the display unit 102 (step S14).

  This point will be described with reference to FIGS. When an incoming call arrives at a personal number, a search is performed as described in the lower part of FIG. Specifically, the phone book is searched in the reading order. In this case, since a symbol such as “*” is added to the first character of the phone number registered as group 9, when searching in the order of reading, the group other than group 9 is given priority. Will be searched.

  For example, assume that the current calling number is “1234”. In this case, if the search is performed in the order of reading using “1234” as a search key, “Furigana: Yamada Taro, Name: XX Trading, Phone Number 1: 1234, Group: 9” is not used. Name: Taro Yamada, phone number 1: 1234, group: 1 ”is identified.

  Then, the control unit 101 displays the name “Taro Yamada” on the display unit 101 based on the search result. A display example in this case is shown in the lower part of FIG. Referring to the lower part of FIG. 6, the display unit 102 displays a display indicating that a call is being received, a display indicating that the caller is “Taro Yamada”, and a calling number “1234”.

  The user who uses the representative number referring to such a display knows that the incoming call is from a person named “Taro Yamada”. And it is possible to respond to the telephone after grasping it.

  Note that the telephone number may not be displayed depending on the size of the display unit 102. In addition, a message indicating that an incoming call is being received is displayed on the screen, or alternatively, for example, an LED indicating an incoming call may be blinked or a ringing tone may be sounded.

  Regardless of which step S13 and step S14 are performed, the process proceeds to step S15.

  In step S15, the call indicating the incoming call or the sound output is continued. Then, it is confirmed whether or not the user has gone off-hook by an action such as picking up the handset.

  If it becomes off-hook during the call (Yes in step S15), the call is started (step S16).

  On the other hand, if the call does not go off-hook during the call, the incoming call is disconnected. Alternatively, after a predetermined time elapses, the answering machine function is activated and voice recording is performed.

  As described above, in the present embodiment, even if the same phone book is used, the content to be displayed can be switched between when the call is received at the representative number and when the call is received at the personal number. Play.

  In addition, in the case of an incoming call to the representative number, the person who receives the incoming call is the person of the receptionist, so even if the personal name is displayed, it is unknown. For this reason, it is easier to answer the phone if the company name is displayed. Considering this, the company name can be displayed when a call is received at the representative number.

  On the other hand, in the case of a dial-in incoming call to a person in charge of the sales department etc., it is possible to receive a call according to the caller by displaying with a personal name already known rather than displaying the company name. is there. Therefore, when there is an incoming call to a personal number such as dial-in incoming call, the personal name can be displayed.

  In addition, the present embodiment has an effect that display switching can be realized only by adding the phonebook data for the representative number to the phonebook used so far.

<Second Embodiment>
Next, a second embodiment will be described.

  In the first embodiment, information to be displayed is switched depending on whether the telephone number assigned to the display switching telephone 100 is a representative number or a personal telephone number. On the other hand, in the second embodiment, information to be displayed at the time of disaster (or at the time of disaster training) and at the normal time (that is, when no disaster has occurred and no disaster training has been performed). Switch.

  Here, the basic configuration of the present embodiment is the same as that of the first embodiment described with reference to FIGS.

  Next, as a premise for explaining the processing of the control unit 101 in the present embodiment, a technique for distinguishing between a normal time and a disaster occurrence time (or disaster training time) will be described.

  First, it is conceivable that the display switching telephone 100 receives a notification from the exchange 200 or another server device, so that the display switching telephone 100 distinguishes between a normal time and a disaster occurrence time (or disaster training time). .

  An example of such a technique is described in Patent Document 3, for example.

  As described in Patent Document 3, when an earthquake occurs in any place, the seismometer closest to the epicenter first senses the seismic wave and transmits the observation data to the Japan Meteorological Agency. The Japan Meteorological Agency analyzes the data with a computer and calculates the estimated time, location, and magnitude (magnitude) of the earthquake.

  The estimated value of the earthquake occurrence time, occurrence location, and scale (magnitude) calculated in this way is transmitted as an earthquake early warning to a broadcasting station and other various organizations. Earthquake information is also sent to the earthquake information distribution server of the information distributor registered as one of them, and the earthquake information distribution server sends the earthquake information received from the Japan Meteorological Agency to each contracted terminal device. Send.

  In addition, when a power failure occurs within a certain time after receiving the earthquake early warning, the terminal device uses a general analog telephone line in which the line is alive even if the power failure occurs, to the tsunami information distribution server 6. Call the assigned telephone number and receive tsunami information via the analog network.

  By using the technology described in the cited document 3 and the like, for example, the display switching telephone 100 receives the earthquake information transmitted from the earthquake information distribution server via the exchange 200, so that the disaster occurs. I understand.

  In addition, for example, when a disaster occurs, a user in each department is notified of the occurrence of a disaster or disaster training through a broadcast in the building, and the user who hears this changes the setting of the display switching telephone 100. The display switching telephone 100 may be able to determine that (or during disaster training).

  Further, the display switching telephone 100 may be incorporated with a sensor for detecting vibration caused by an earthquake, a sensor for detecting the generation of smoke due to fire, and the like. The display switching telephone 100 may determine that a disaster such as an earthquake or a fire has occurred based on the detection results of these sensors.

  Next, the telephone directory in the present embodiment will be described with reference to FIG.

  Here, the outline of the telephone directory in the present embodiment is substantially the same as the specific example of the telephone directory described with reference to FIG.

  However, in the first embodiment, the group 9 is linked to the name displayed in the case of the representative number and a symbol such as * is added in front of the reading, but in this embodiment, when a disaster occurs (or The group 9 is linked to the name displayed in the case of disaster training), and a symbol such as * is added in front of the reading.

  In the first embodiment, a company name or the like is associated with a name such as “XX Trading” or “XX Manufactory”. In this regard, in this embodiment, names such as “Disaster Headquarters” and “Emergency Contact Group” are useful names for determining whether to respond to incoming calls when a disaster occurs (or during disaster training). It is different in terms of tying. Specifically, in the first embodiment, “Furigana: * Oki, name: XX factory, telephone number 1: 5678, group: 9” is registered, but in this embodiment, “Furigana: * Oki”. , Name: disaster headquarters, telephone number 1: 5678, group: 9 ". Similarly, in the first embodiment, “Furigana: * Yamada Taro, name: XX Shoji, phone number 1: 1234, group: 9” is registered, but in this embodiment, “Frigana: * Yamada Taro” is registered. , Name: emergency contact group, telephone number 1: 1234, group: 9 ".

  Next, with reference to the flowchart of FIG. 8 and FIG. 9 and FIG.

  It is assumed that a telephone number such as a representative telephone number or a personal telephone number is assigned to each display switching telephone 100 as a premise for performing processing at the time of incoming call described below. Further, the display switching telephone 100 can determine whether or not a disaster has occurred (or whether or not it is during a disaster training) by receiving a notification from the exchange 200 as described above. It shall be.

  First, the control unit 101 confirms whether there is an incoming call at a predetermined interval (step S21). If there is no incoming call, the incoming call confirmation is continued (No in step S21).

  If there is an incoming call from any telephone through the exchange 200 (Yes in step S2), the process proceeds to step S22.

  In step S22, it is determined whether the current disaster occurs (or the current disaster training, which is described only as the disaster occurs in the figure) or the normal time.

  Here, it is assumed that, as a result of the confirmation, a disaster has occurred (or at the time of disaster training) (Yes in step S22: when a disaster occurs). In that case, the phone book is searched by the control unit 101 and responds to an incoming call when a disaster occurs (or during disaster training), such as “Disaster Headquarters” or “Emergency Contact Group” linked to the phone number. A name that is useful for determining whether or not to do so is identified as a name. Then, the specified name is displayed on the display unit 102 (step S23).

  This point will be described with reference to FIGS. When an incoming call occurs when a disaster occurs (or during disaster training), a search is performed as described in the upper part of FIG. Specifically, information registered as group 9 is searched preferentially rather than groups registered as groups 1 to 8.

  For example, assume that the current calling number is “1234”. In this case, “1234” is searched for telephone number 1 and telephone number 2 of group 9 as a search key.

  As a result, “Furigana: * Yamada Taro, name: emergency contact team, telephone number 1: 1234, group: 9” is specified as a search result. The telephone number for this time was registered in group 9. However, if the group 9 is not registered, that is, if only the personal name is registered, the personal name is specified.

  The control unit 101 displays the name “emergency contact group” on the display unit 102 based on the search result. A display example in this case is shown in the upper part of FIG. Referring to the upper part of FIG. 10, the display unit 102 displays a display indicating that a call is being received, a display indicating that the caller is “emergency contact group”, and a calling number “1234”.

  A user who refers to such display when a disaster occurs (or during disaster training) knows that the incoming call is from a person belonging to the “emergency contact group”. And it is possible to respond to the telephone after grasping it.

  Note that the telephone number may not be displayed depending on the size of the display unit 102. In addition, a message indicating that an incoming call is being received is displayed on the screen, or alternatively, for example, an LED indicating an incoming call may be blinked or a ringing tone may be sounded.

  On the other hand, it is assumed that the result of the confirmation in step S22 is normal time (No in step S22: normal time). In that case, the telephone book is searched by the control unit 101, and the personal name associated with the telephone number is specified. Then, the identified personal name is displayed on the display unit 102 (step S24).

  This point will be described with reference to FIGS. When an incoming call is received during normal times, a search is performed as described in the lower part of FIG. Specifically, the phone book is searched in the reading order. In this case, since a symbol such as “*” is added to the first character of the phone number registered as group 9, when searching in the order of reading, the group other than group 9 is given priority. Will be searched.

  For example, assume that the current calling number is “1234”. In this case, if the search is performed in the order of readings using “1234” as a search key, “Furigana: Yamada Taro, Name: Emergency Contact Team, Phone Number 1: 1234, Group: 9” is not used. Name: Taro Yamada, phone number 1: 1234, group: 1 ”is identified.

  Then, the control unit 101 displays the name “Taro Yamada” on the display unit 102 based on the search result. A display example in this case is shown in the lower part of FIG. Referring to the lower part of FIG. 10, the display unit 102 displays a display indicating that a call is being received, a display indicating that the caller is “Taro Yamada”, and a calling number “1234”.

  A user who is using the time of disaster occurrence (or at the time of disaster training) referring to such a display knows that the incoming call is from a person named “Taro Yamada”. And it is possible to respond to the telephone after grasping it.

  Note that the telephone number may not be displayed depending on the size of the display unit 102. In addition, a message indicating that an incoming call is being received is displayed on the screen, or alternatively, for example, an LED indicating an incoming call may be blinked or a ringing tone may be sounded.

  Regardless of whether step S23 or step S24 is performed, the process proceeds to step S25.

  Here, the process of the following step S25 is equivalent to the process in step S15 described with reference to FIG. Similarly, the process in step S26 is equivalent to the process in step S16 described with reference to FIG. Furthermore, the process in step S27 is equivalent to the process in step S17 described with reference to FIG.

  Accordingly, the description of steps S25 to S27 is omitted.

  As described above, in the present embodiment, even if the same phone book is used, it is possible to switch the contents displayed at the time of disaster (or at the time of disaster training) and normal time. Play.

  For example, when there is an incoming call during normal times, phone numbers are searched from the phone book in order of reading, and the corresponding names are displayed. For example, if there is a call from “1234”, the corresponding name “Taro Yamada” is displayed from the phone book. “Disaster headquarters” is not displayed because the reading order is correct.

  In the event of a disaster (or during disaster training), the priority group setting of the telephone is set to “Group 9”. With this setting, when there is an incoming call from “1234”, the corresponding name “Emergency Contact Group” is displayed from the telephone directory. By displaying “Emergency contact group”, it is known that the contact is related to a disaster, and it is possible to prevent an emergency contact leak.

  That is, since a predetermined group is prioritized, a plurality of name displays can be switched and used according to the situation.

  In addition, in this embodiment, there is an effect that display switching can be realized only by adding telephone book data for disasters to the telephone book used so far.

<Third Embodiment>
Next, a third embodiment will be described.

  In the first embodiment, information to be displayed is switched depending on whether the telephone number assigned to the display switching telephone 100 is a representative number or a personal telephone number. In the second embodiment, the information to be displayed is switched between when a disaster occurs (or during disaster training) and during normal times (that is, when no disaster has occurred and no disaster training has been performed). It was.

  On the other hand, in this embodiment, information to be displayed is switched between the night mode and the normal mode (that is, the mode when the night mode is not set).

  Here, the basic configuration of the present embodiment is the same as that of the first embodiment described with reference to FIGS.

  Next, as a premise for explaining the processing of the control unit 101 in this embodiment, a technique for distinguishing between the normal mode and the night mode will be described.

  Two modes, normal mode and night mode, are prepared, and when the switching time from normal mode to night mode is reached, switching from normal mode to night mode restricts functions such as reducing the ringtone. Or a telephone that activates an answering machine function.

  Such a telephone is described in Patent Document 4, for example. In the telephone set described in Patent Document 4, at the time of switching from the normal mode to the night mode, even if there is a person near the key telephone housed in the extension of the main device, the night mode is set. The purpose is to prevent.

  In order to achieve such an object, when it is time to switch to the night mode, the mode is automatically switched to the night mode only when it is estimated that there is no person near the key telephone.

  Also in this embodiment, it is only necessary to switch from the normal mode to the night mode by using such a technique. For example, the switching time from the normal mode to the night mode may be changed on weekdays and holidays, or the switching time from the normal mode to the night mode may be changed depending on the day of the week. The switching from the normal mode to the night mode may be performed independently by each display switching telephone 100, but may be switched from the normal mode to the night mode according to an instruction from the exchange 200.

  Next, the telephone directory in the present embodiment will be described with reference to FIG.

  Here, the outline of the telephone directory in the present embodiment is substantially the same as the specific example of the telephone directory described with reference to FIG. 3 and FIG.

  However, in the first embodiment, the group 9 is linked to the name displayed in the case of the representative number, and a symbol such as * is added in front of the reading. In the second embodiment, the group 9 is linked to the name displayed when a disaster occurs (or at the time of disaster training), and a symbol such as * is added before the reading.

  In contrast, the present embodiment is different in that the group 9 is linked to the name displayed in the night mode and a symbol such as * is added in front of the reading.

  In the first embodiment, a company name or the like is associated with a name such as “XX Trading” or “XX Manufactory”. In the second embodiment, names such as “Disaster Headquarters” and “Emergency Contact Team” are names that are useful for determining whether to respond to incoming calls when a disaster occurs (or during disaster training). It was tied as.

  On the other hand, in this embodiment, it differs in the point linked | related with the name relevant to night mode as a name. Specifically, for example, in the first embodiment, “Furigana: * Oki, Name: XX Manufactory, telephone number 1: 5678, group: 9” is registered, but in this embodiment, “Frigana: * Oki, name: xx security company, phone number 1: 5678, group: 9 ". Similarly, in the first embodiment, “Furigana: * Yamada Taro, name: XX Shoji, phone number 1: 1234, group: 9” is registered, but in this embodiment, “Frigana: * Yamada Taro” is registered. , Name: XX branch office, telephone number 1: 1234, group: 9 ".

  In this regard, for example, there may be a case where all employees return to work at night and only a security officer is in the building. In such a case, the security officer usually does not respond to the telephone, but it may be possible to make a telephone response to an incoming call from the security company. Therefore, it is conceivable to display a company name such as “xx security company”.

  In addition, it may be possible to switch to the night mode at the time when the reception time for inquiries from customers ends. In this case, the employee does not respond to the incoming call from the customer, but it may be possible to make a telephone response to the incoming call from the company's branch office. Therefore, it may be possible to display the name of the company's own branch office such as “XX branch office”.

  For example, when this branch office is located in a foreign country, there may be a case where there is an incoming call from this branch office after a normal business hours due to time difference. In such a case, if the branch office name is displayed, it is possible to cope with incoming calls from the branch office even during a time period when the telephone is not normally handled.

  Next, with reference to the flowchart of FIG. 12 and FIG. 13 and FIG.

  It is assumed that a telephone number such as a representative telephone number or a personal telephone number is assigned to each display switching telephone 100 as a premise for performing processing at the time of incoming call described below. In addition, the display switching telephone 100 can determine whether it is currently in the night mode or the normal mode by a method such as switching to the night mode at the predetermined switching time as described above. To do.

  First, the control unit 101 confirms whether there is an incoming call at a predetermined interval (step S31). If there is no incoming call, confirmation of the incoming call is continued (No in step S31).

  When an incoming call is received from any telephone through the exchange 200 (Yes in step S3), the process proceeds to step S32.

  In step S32, it is determined whether the current mode is the night mode or the normal mode.

  Here, it is assumed that the night mode is selected as a result of the confirmation (Yes in step S32: night mode). In that case, the phone book is searched by the control unit 101, and whether or not to accept an incoming call in the night mode such as “XX security company” or “XX branch office” linked to the telephone number is determined. Names that are useful for the determination are identified as names. Then, the specified name is displayed on the display unit 102 (step S33).

  This point will be described with reference to FIGS. When an incoming call is made in the night mode, a search is performed as described in the upper part of FIG. Specifically, information registered as group 9 is searched preferentially rather than groups registered as groups 1 to 8.

  For example, assume that the current calling number is “1234”. In this case, “1234” is searched for telephone number 1 and telephone number 2 of group 9 as a search key.

  As a result of the search, “phonetic: * Yamada Taro, name: XX branch office, telephone number 1: 1234, group: 9” is specified. The telephone number for this time was registered in group 9. However, if the group 9 is not registered, that is, if only the personal name is registered, the personal name is specified.

  Then, the control unit 101 displays the name “XX branch office” on the display unit 102 based on the search result. A display example in this case is shown in the upper part of FIG. Referring to the upper part of FIG. 14, the display unit 102 displays a display indicating that a call is being received, a display that the caller is “XX branch office”, and a calling number “1234”.

  A user who refers to such a display in the night mode knows that the incoming call is from a person belonging to “XX branch office”. And it is possible to respond to the telephone after grasping it. For example, since it is understood that it is not from the customer but from the company's own branch office, it is possible to respond to incoming calls in consideration of it.

  Note that the telephone number may not be displayed depending on the size of the display unit 102. In addition, a message indicating that an incoming call is being received is displayed on the screen, or alternatively, for example, an LED indicating an incoming call may be blinked or a ringing tone may be sounded.

  On the other hand, as a result of the confirmation in step S32, it is assumed that the current mode is the normal mode (No in step S32: normal mode). In that case, the telephone book is searched by the control unit 101, and the personal name associated with the telephone number is specified. Then, the specified personal name is displayed on the display unit 102 (step S34).

  This point will be described with reference to FIGS. When an incoming call is made in the normal mode, a search is performed as described in the lower part of FIG. Specifically, the phone book is searched in the reading order. In this case, since a symbol such as “*” is added to the first character of the phone number registered as group 9, when searching in the order of reading, the group other than group 9 is given priority. Will be searched.

  For example, assume that the current calling number is “1234”. In this case, if the search is performed in the order of reading with “1234” as a search key, “Furigana: Yamada Taro, Name: ○○ Branch, Phone Number: 1234, Group: 9” is not used. Name: Taro Yamada, phone number 1: 1234, group: 1 ”is identified.

  Then, the control unit 101 displays the name “Taro Yamada” on the display unit 102 based on the search result. A display example in this case is shown in the lower part of FIG. Referring to the lower part of FIG. 14, the display unit 102 displays a display indicating that a call is being received, a display indicating that the caller is “Taro Yamada”, and a calling number “1234”.

  A user who uses the night mode with reference to such a display knows that the incoming call is from a person named “Taro Yamada”. And it is possible to respond to the telephone after grasping it.

  Note that the telephone number may not be displayed depending on the size of the display unit 102. In addition, a message indicating that an incoming call is being received is displayed on the screen, or alternatively, for example, an LED indicating an incoming call may be blinked or a ringing tone may be sounded.

  Regardless of whether step S33 or step S34 is performed, the process proceeds to step S35.

  Here, the process of the following step S35 is equivalent to the process in step S15 described with reference to FIG. Similarly, the process in step S36 is equivalent to the process in step S16 described with reference to FIG. Furthermore, the process in step S37 is equivalent to the process in step S17 described with reference to FIG.

  Accordingly, the description of steps S35 to S37 is omitted.

  In the present embodiment described above, even if the same phone book is used, there is an effect that the contents to be displayed can be switched between the night mode and the normal mode.

  For example, when there is an incoming call in the normal mode, phone numbers are searched from the phone book in order of reading, and the corresponding names are displayed. For example, if there is a call from “1234”, the corresponding name “Taro Yamada” is displayed from the phone book. Since the reading is in order, “XX branch office” is not displayed.

  In the night mode, the priority group setting of the telephone is set to “group 9”. With this setting, when there is an incoming call from “1234”, the corresponding name “XX branch office” is displayed from the telephone directory. By displaying “XX branch office”, it is known that the contact is from a person concerned in the company, and it is possible to determine whether or not to respond to the telephone.

  That is, since a predetermined group is prioritized, a plurality of name displays can be switched and used according to the situation.

  In addition, the present embodiment also has an effect that display switching can be realized simply by adding the telephone directory data for the night mode to the telephone directory used so far.

  Moreover, although the above-described embodiment is a preferred embodiment of the present invention, the scope of the present invention is not limited only to the above-described embodiment, and various modifications are made without departing from the gist of the present invention. Implementation in the form is possible.

  For example, in each embodiment, the priority group setting of the telephone is set to “group 9” when the representative telephone is received, during a disaster, and in the night mode. Such setting may be performed manually, or each device in the telephone system 10 may automatically change the setting.

  Further, in each of the above-described embodiments, the telephone book is created for the telephone number of the outside line, but the telephone book may be created for the number of the extension line.

  Further, the exchange 200 may search the telephone directory and display the search result on the display switching telephone 100.

  Further, the display switching telephone 100 may be a fixed telephone using an analog line or an IP telephone using a digital line.

  Furthermore, the number of display switching telephones 100 included in the telephone system 10 may be an arbitrary number. Furthermore, the number of departments in which the display switching telephone 100 is installed may be an arbitrary number. Furthermore, a plurality of display switching telephones 100 may be installed in each department. Further, the display switching telephone 100 to which the representative telephone number is assigned and the display switching telephone 100 to which the personal telephone number is assigned may be mixed in one department.

  Furthermore, you may make it combine each embodiment. In that case, a predetermined group other than the group 9 may be used as a target to be preferentially searched according to the situation. For example, information such as a company name for realizing the first embodiment is registered as group 8 instead of group 9. In addition, information such as a name used at the time of a disaster for realizing the second embodiment is registered in the group 9. If there is an incoming call to the representative department's telephone number, the group 8 is preferentially searched. In the event of a disaster, the search is prioritized from the group 9. By doing in this way, each embodiment can be used in combination.

  Further, in each embodiment, the display information may be switched not only when an incoming call is received but also when a call is made. For example, if the display information is switched at the time of transmission in the second embodiment, the group 9 is preferentially searched in the event of a disaster, so that the telephone number at the time of the disaster is displayed in the same group. For this reason, it is easy to find an urgent contact information when making a call.

  Note that each of the display switching telephone and the exchange included in the telephone system can be realized by hardware, software, or a combination thereof. In addition, switching of display information performed by a display switching telephone and an exchange included in the above telephone system can be realized by hardware, software, or a combination thereof. Here, “realized by software” means realized by a computer reading and executing a program.

  The program may be stored using various types of non-transitory computer readable media and supplied to the computer. Non-transitory computer readable media include various types of tangible storage media. Examples of non-transitory computer readable media include magnetic recording media (for example, flexible disks, magnetic tapes, hard disk drives), magneto-optical recording media (for example, magneto-optical disks), CD-ROMs (Read Only Memory), CD- R, CD-R / W, and semiconductor memory (for example, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, RAM (random access memory)). The program may also be supplied to the computer by various types of transitory computer readable media. Examples of transitory computer readable media include electrical signals, optical signals, and electromagnetic waves. The temporary computer-readable medium can supply the program to the computer via a wired communication path such as an electric wire and an optical fiber, or a wireless communication path.
