Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone, and more particularly to a telephone suitable for appropriately ringing a ringing tone.

[0002]

2. Description of the Related Art An image communication telephone, like an ordinary telephone having only a voice communication function, always sounds a ringing tone when a call arrives, regardless of the home status of the other party.

That is, as shown in FIG.
In the incoming call waiting state, it is determined whether or not there is a call (step S1
31) If there is a call, the process proceeds to a call routine to perform a predetermined call process (step S132), and if there is no call, it is determined whether there is an incoming call (step S133). As a result, if there is no incoming call, the process returns to step S131 to determine whether or not there is an outgoing call.

On the other hand, if there is an incoming call, the
The call bell is sounded regardless of the absence (step S134).
When no one is at home and the handset is off-hook even after ringing the calling bell a predetermined number of times (step S135), the communication is disconnected after the answering machine recording / recording, or the communication is immediately disconnected. Yes (step S136).

On the other hand, when someone is at home and the handset is picked up while ringing the call bell and goes off-hook (step S137), the transmission / reception of the call contents input / output via the handset is controlled thereafter. Then, the handset is hooked on-hook to disconnect the communication (step S138). In this case, the at-home person who picked up the handset, if it is a telephone call to himself or other at-home person, as it is, or calls another at-home person to the telephone port to make a call, and if it is a telephone call to an absent person, You will hang up by listening to the message.

[0006]

However, in the above-mentioned conventional telephone, even if the person who wants to call is absent but the other person is at home on the called side, the calling bell is rung. , Often annoying to other called-side home users.

The present invention has been made under the above circumstances, and its purpose is to control the ringing of a ringing bell in a manner that does not cause an inconvenience to a person other than the person who wishes to communicate at the called side. To provide a telephone to get.

[0008]

In order to achieve the above object,
According to the present invention, there is provided information input means for inputting presence / absence information of each constituent member on the self side, and automatic reception response of the called side input by the input means without ringing a calling bell at the time of incoming call. Information transmitting means for automatically transmitting the presence / absence information of each constituent member to the calling side, and presence / absence information of each constituent member of the called side transmitted and output by the information transmitting means is output at the calling side. Whether to ring the call bell of the callee or not to ring the call bell of the callee based on the information output means and the presence / absence information of each member of the callee that is output by the output means And a signal transmitting means for transmitting a signal indicating at least from the calling side to the called side.

[0009]

When the incoming call is received, the information transmitting means responds to the automatic incoming call response without ringing the calling bell, and outputs the presence / absence information of each constituent member of the called side input by the input means. Automatically transmitted to the calling side as a signal or image signal. On the other hand, on the calling side, the presence / absence information of each constituent member on the called side that has been transmitted and output is output by voice or displayed.

Therefore, if the calling party recognizes the presence / absence of the person he / she desires to communicate with based on this output information, and the person he / she wishes to communicate with is at home, etc.,
A signal for ringing the ringing ring of the called side is transmitted to the called side by the signal transmitting means, and if the person whom the user desires to communicate is not at home, etc. If the person who wishes to communicate is not at home by transmitting the signal for performing the communication or the communication disconnection signal to the called side by the signal transmitting means, the called side is called. By preventing the ringing of the bell even once, it is possible to prevent annoying other in-home persons on the called side.

Next, the operation of the application relating to the information display peculiar to this apparatus will be described with reference to FIGS.

2 to 9 are flowcharts showing various application operations, FIGS. 10 and 11 are screen display examples in each state, and FIG. 12 is a state transition diagram thereof. It is assumed here that the operation unit 10 is a touch panel and the display unit 2 is a liquid crystal display, and a liquid crystal touch panel 210 (see FIG. 1) in which these are stacked and integrated is used, and a display item on the display unit 2 can be touched. Allows various commands to be input.

FIG. 2 is a flow chart showing the initial screen when the power of the device is turned on. The screen of the liquid crystal touch panel 210 in the initial state when the power is turned on is a "dial input screen" that allows the user to make and receive calls at any time. (Calling / calling waiting state) ”(step 201, hereinafter step is referred to as S). That is, when the power is turned on, as shown in FIG. 10A, the self-portrait is displayed on the child screen 19 in the "dial input screen (calling / call waiting state)", and the state before communication is displayed. I can confirm. On the main screen 18, there are a number key 20 for inputting a dial number, a key input number display section 21, a sub address display section 22, a clear key 24 for deleting the input number, and one character of the input number, which are related to the calling side. A backspace key 25 to be deleted, a calling key 23 for starting a calling, and a switching key 26 are displayed on the information display screen, which is a feature of this apparatus.

Next, the operation in the state in which the "dial input screen (calling / call waiting state)" of FIG. 10 (a) is displayed will be described based on the flowchart of FIG.

In the state of the "dial input screen (calling / incoming call waiting state)" of FIG. 10 (a), the call bell is displayed even when an absentee receives an incoming call, as in the conventional image communication telephone. It will ring and you will be notified at the telephone outlet that you are absent. However, if you do not want to answer a call that is not addressed to you (S30
1) By pressing the switch key 26 for switching to the information display screen (S302), the screen is switched to the "information display screen (in non-input mode)" shown in FIG. (S303: refer to “a” in FIG. 12), the process may be performed in that state.

When the "information display screen (in the non-input mode)" of S303 is not entered, an incoming call waiting (S304) and an outgoing call waiting (S305) are performed, and when an incoming call occurs, it is processed by the flowchart of FIG. The screen shifts to the “incoming call screen (dial input screen)” shown in FIG. 10C (S306:
(See "b" in FIG. 12). At the time of calling, the telephone number is entered with the numeric keypad 20 (S307), and the dial transmission is started with the calling key 23 (S308).

When the other party does not respond (S30
9), communication is disconnected (S310: see “c” in FIG. 12),
Return to the original call / waiting state. On the other hand, when the other party responds (S309), the image communication telephone of the other party is not in the information display mode but in a normal telephone state (the present device is the state of the dial input screen), and the display information (at-home / out-home information) If no message is received (S311), communication with the other party on the call screen and communication by prerecorded answering machine recording / recording (hereinafter referred to as answering machine) are performed as in the conventional telephone (S312: After the disconnection of communication (S310), the process returns to the outgoing / incoming call waiting state of S304 and S305 (see "e" in FIG. 12). On the other hand, when the other party's image communication telephone is in the information bulletin board mode and the called party's bulletin board information (at-home / out-home information) is received (S311),
The processing moves to the "partner information posting screen" shown in FIG. 10 (b) which is processed by the flowchart of FIG. 4 (S313: FIG. 12).
"F").

Next, the operation when the "partner information posting screen" of FIG. 10 (b) is displayed will be described with reference to the flowchart of FIG.

In the state of the "other party information display screen" of FIG. 10B, the received bulletin information 27 displayed on the liquid crystal touch panel 210 of the other party's image communication telephone is the liquid crystal touch panel 210 of its own image communication telephone. Is displayed in. On the "partner information display screen", a command key 28 for ringing the calling bell of the partner, a command key 29 for activating the answering recording guide of the partner, and a communication disconnection key 30 are also displayed at the same time.

Therefore, based on the information (at-home / out-home information) 27 of the other party (incoming side), the at-home / outside of the other party who wants to talk
The state of going out is confirmed (S401), and if the person who wants to talk is at home and wants to ring the calling bell (S402), the command key 28 for ringing the calling bell of the partner is touched (S403). Then, as in the case of the conventional image communication telephone, the call bell of the called side rings (S404), and if there is a response of the called side (S405), after performing normal communication on the normal screen (S406: figure) 12 "u"), communication is disconnected (S407: see "v" in FIG. 12), and the "dial input screen (call origination / call waiting state)" of FIG. 10A processed by the flowchart of FIG. Return to step S408. on the other hand,
If there is no response from the called side (S405), the communication is immediately cut off (S407), and the screen returns to the "dial input screen (calling / waiting for call waiting state)" of FIG. 10A (S408: FIG. 12).
See "g").

If the person to talk with is absent and he / she does not want to ring the call bell because he / she does not want to disturb other family members at home, it is decided whether or not to activate the answering machine mode (S409). . When it is decided to activate the answering machine mode, the command key 29 for activating the answering machine mode of the other party is touched (S410), and the called party enters the answering machine mode without ringing any ringing bell (S411, The details will be described later). Then, after performing communication based on the answering machine mode (S412: FIG.
The communication is disconnected (see "u") (S407: see "v" in FIG. 12), and the screen returns to the "dial input screen (calling / incoming call waiting state)" in FIG. 10A (S408). On the other hand, when it is determined in S409 that the answering machine mode should not be activated, the communication is immediately disconnected (S407), and the screen returns to the "dial input screen (calling / incoming call waiting state)" of FIG. 10A (S40).
8). In this way, even when the communication is immediately disconnected, the ringing bell on the called side never sounds, of course.

Next, the operation in the state where the "incoming call screen (dial input screen)" of FIG. 10C is displayed will be described with reference to the flowchart of FIG. This "incoming call screen (dial input screen)" is a screen that shifts when an incoming call arrives in the "dial input screen" (normal telephone mode) of FIG. "See), the parent screen 18 displays the" yes "and" no "incoming call answer keys 31, the called party telephone number display 32, and the called party subaddress display 33, and the child screen 19 displays a self-portrait.

This "incoming call screen (dial input screen)"
Then, as in the case of a normal image communication telephone, when answering (S501), the incoming call answer key 31 of "Yes" is touched to perform normal communication on the normal screen, or the incoming call answer key 3
After performing communication based on voice mail without touching 1 (S
502: See “w” in FIG. 12) and disconnect communication (S503:
12 (see "x"), the screen returns to the "dial input screen (calling / incoming call waiting state)" of FIG. 10A (S504). On the other hand, if the user does not want to respond (S501), the communication is disconnected by touching the “No” incoming response key 31 (S503: see “c” in FIG. 12), and the “dial input screen” in FIG. 10A is displayed. (Call / waiting for call) "(S5
04).

Next, when the user does not want to answer the telephone not addressed to himself, the operation is switched by the touch operation of the switching key 26 on the "dial input screen (call origination / call waiting state)" of FIG. 10 (a). The operation of the "information display screen (in non-input mode / waiting for incoming call)" of FIG. 10D will be described based on the flowchart of FIG.

In the "information display screen (in non-input mode)" waiting for incoming call "" of FIG. 10 (d), the home / out-of-home information (posting information) of the family has already been input to his / her image communication telephone. This is the screen when waiting for an incoming call with the home / out-home information of the family being displayed, and the input mode switching key 3
5. The switch key 36 for switching to the dial input screen is also displayed at the same time.

When it is desired to update the in-home / out-of-home information being displayed (S601), by touching the input mode switching key 35 (S602: see "i" in FIG. 12), the process shown in the flowchart of FIG. Since the screen shifts to "information display screen (in input mode)" waiting for incoming call "of b) (S6)
03), and update it on the “information display screen (in input mode)“ waiting for incoming call ””.

When an incoming call arrives in the state of "information display screen (in non-input mode)" waiting for incoming call "of FIG. 10 (d) (S
604, do not ring the ringing bell for this incoming call),
11E, which is processed by the flow chart of FIG. 7, shifts to the "incoming call screen (non-input mode)" at the time of information display screen "(S605: see" h "in FIG. 12), and call control is performed. Be seen. When a call is made or it is desired to exit from the "information display screen (in non-input mode)" waiting for incoming call "(S606), the switch key 3 for switching to the dial input screen is displayed.
When 6 is touched (S607), the screen shifts to the "dial input screen (calling / incoming call waiting state)" in FIG. 10A (S608: see "s" in FIG. 12).

Then, when an incoming call arrives in the state of "information display screen (in non-input mode)" waiting for incoming call "of FIG. 10 (d),""of FIG. 11 (a) is automatically switched. The operation of the "incoming call screen (in non-input mode / information display screen)" will be described with reference to the flowchart of FIG.

In the "incoming call screen (non-input mode / information posting screen)" of FIG. 11 (a), at-home / out-of-home information (posting information), an input mode switching key 35, and a dial input screen switching key 36 are displayed. , Incoming call communication 37 is displayed.

The "incoming call screen (in non-input mode / information posting screen)" of FIG. 11 (a) is the state of "information posting screen (in non-input mode)" waiting for incoming call "as described above. When an incoming call comes in, the screen is automatically switched to, but the incoming call is answered without answering the ringing bell (see “h” in FIG. 12) and the bulletin information (at-home / out-home information) Is automatically transmitted to the calling side as screen information (S701) and waits for a command from the calling side for a predetermined time (S702, S703).
During this period, the "incoming call communication" 37 is displayed so that it can be seen that the image communication telephone is automatically communicating.

In this way, the in-home / out-home information is transmitted to the calling side, and an automatic incoming call (incoming call) is made without ringing the ringing bell.
Since the caller responds, the calling side looks at the transmitted in-home / out-home information {see FIG. 10 (b)}, and if the other party to be called is out, either the answering machine command described below or By immediately disconnecting the communication, the calling bell does not ring at all, and it is not necessary to bother other persons at home on the called side.

That is, when the answering machine command is received from the calling side (S704), the calling bell does not ring and the answering machine mode is entered this time (S705). Therefore, communication based on the recorded message is performed (S706: FIG.
(See “y”), and when the communication ends, the communication is disconnected (S708: see “m” in FIG. 12), and the original FIG.
Return to "Information display screen (in non-input mode)" Incoming call waiting "".

On the other hand, when the command for ringing the ringing bell is received (S704), the ringing ring is ringed (S70).
9). At this time, the screen is switched to the "'incoming call screen (in non-input mode and at the time of receiving a command to ring the ringing bell)" in FIG. 10C (see "k" in FIG. 12). Therefore,
Similar to a normal telephone, when the incoming call response key 31 is answered to the calling bell, the normal communication is performed on the normal screen (S710), the communication is disconnected (S707), and the original FIG. “Information display screen (in non-input mode)“ waiting for incoming call ”” (S708: see “l” and “m” in FIG. 12). On the other hand, when the call is not answered, the communication is immediately disconnected (S709: refer to “n” in FIG. 12) and the original “information display screen (in non-input mode)“ waiting for incoming call ”is returned.

When the waiting timer counts up while waiting for a command from the calling side (S70)
3) Then, the communication is disconnected (S707) and the original "information display screen (in non-input mode)" waiting for incoming call "is returned to (S70).
8). The screen shifts to the original “information display screen (in non-input mode / waiting for incoming call)” (S713). In this way, even when the standby timer counts up and disconnects communication,
The call bell never rings.

Next, the "information display screen" of FIG. 11 (b) for updating the home / out-home information from the state of "information display screen (in non-input mode)" waiting for incoming call "of FIG. 10 (d) The processing when the "waiting for incoming call" is switched (in the input mode) will be described with reference to the flowchart of FIG.

In this "information display screen (in input mode)" waiting for incoming call "", the home / out-home information related to the registration of his family is displayed on the information display screen 34 of his terminal. In addition to this home / out-of-home information, there is an “input mode” 38 for distinguishing from the non-input mode, and a function key 39 for registering a word at the time of input (bath, at home, going out, etc.). Is displayed. So, if you want to update your at-home / out-of-home information, you can take a bath, go home, or go out.
It suffices to update and input using the function keys 39 such as

When an incoming call arrives during this update input (S80
1) is processed according to the flowchart of FIG.
“Incoming call screen (when in input mode / information display screen)” in (b)
(S802: see “o” in FIG. 12). When the update input is completed, the input mode switching key 35 is touched (S803). Then, the display information (at-home / out-home information) is updated while shifting to “information display screen (in non-input mode)“ waiting for incoming call ”in FIG. 10D (S804: refer to“ t ”in FIG. 12). It

Next, the process of the incoming call screen (in the input mode / information display screen) of FIG. 10 (c) when the incoming call arrives during the above update input is shown in the flowchart of FIG. It will be described based on.

In this "incoming call screen (in the input mode / information display screen)", when answering (S901), as in a normal telephone, the incoming call answer key 31 of "Yes" is touched to display the normal screen. Perform normal communication (S902: FIG. 12).
(See “p”), the communication is disconnected (S903: see “q” in FIG. 12), and the screen returns to “information display screen (in input mode)“ waiting for incoming call ”in FIG. 11B before the incoming call arrives. On the other hand, if the user does not want to respond (S901), the incoming call response key 31 of "No" is touched to disconnect the communication (S90).
3: see FIG. 12 "r"), FIG. 11 (b) before an incoming call arrives.
Return to “Information display screen (in input mode)“ Incoming call waiting ”” (S904).

When an incoming call is received while the home / out-home information is being updated, as described above, the screen shifts to the "incoming call screen (in input mode / information display screen)" of FIG. 10 (c). Then, the in-home / out-home information updated and input up to that point is not confirmed and becomes invalid. However, when the process on this "incoming call screen (in the input mode / information display screen)" is completed, the immediately preceding FIG. ) "Information display screen (in input mode)" waiting for incoming call "", the home / out-home information is re-updated and input at that time, and then the input mode switching key 35 is touched, as shown in FIG.
