Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone having a function of receiving telephone number data of a caller, and more particularly
If the caller's phone number data is not added, or if the caller's phone number data cannot be determined,
The present invention relates to a telephone capable of starting a call on a called side when rejecting a call for a call from a caller and confirming that a signal indicating the predetermined password has arrived from the caller.

[0002]

2. Description of the Related Art In recent years, telephones (for example, telephones with an ID number display) having a function of displaying a telephone number of a caller have appeared. In order to refuse to receive a call that you do not want to receive, if the telephone number data of the caller is not added at the time of the incoming call, the telephone does not call the called side, for example, "Currently, Please let me know your phone number and call back again. "
Some have a special function that can reject a telephone call on the called side. However, even if the caller is informed of the telephone number in this way, for example, if the caller is a public telephone, the caller's telephone number cannot be notified to the called party, and the called party cannot be notified. May not be able to make phone calls.

[0003]

In order to cope with such a situation, for example, in the case of an incoming call from a public telephone or the like, the receiving side sends a message "from the customer's convenience , Please enter your home phone number with a tone signal. ", Prompt the user to enter the home phone number, and the tone signal of that phone number reaches the called party. In such a case, a countermeasure such as displaying the telephone number on the display device of the telephone set on the receiving side and then calling the receiving side is also conceivable. However, if the receiving side can receive the tone signal of the telephone number transmitted from the public telephone or the like as described above, the transmitting side sets its own telephone number to one.
This operation is very troublesome because it is necessary to input about zero digits. Also, if a random number is input to the caller, there is a problem that the call is made on the callee, which may impair the function of rejecting calls that one does not want to receive. The present invention has been made in order to solve the above-described problems, and it is an object of the present invention to provide a telephone that can reliably reject a call of an incoming call whose source is not clear and can reliably call a necessary incoming call. Aim.

[0004]

Means for Solving the Problems and Effects of the Invention To achieve this object, according to the first aspect of the present invention, a source telephone number for determining whether or not a source telephone number is added An additional discriminating means and a source telephone number reading means for reading the source telephone number data are provided, and when the source telephone number is not added or the source telephone number data cannot be read, In a telephone capable of rejecting a call from a caller from a caller, a password input notifying means for notifying the caller so as to input a predetermined password, and Password identification means for determining whether or not a signal indicating the personal identification number has arrived, and a call for confirming that the signal indicating the predetermined personal identification number has arrived and starting a call on the called side. And characterized in that it comprises a means.

[0005] Thereby, the telephone can reject the incoming call when the telephone number data of the caller is not added or the telephone number data of the caller cannot be read. However, even if the incoming call is rejected, the called telephone notifies the caller to input a predetermined password,
Thereafter, when it is confirmed that a signal indicating the predetermined password has arrived from the caller, the call on the called side is started. Therefore, according to this telephone, a call for an incoming call whose source is not clear such that the caller's telephone number is not added or the caller's telephone number data cannot be read is definitely rejected. However, a call can be made for an incoming call that is communicated by inputting a predetermined password.

According to a second aspect of the present invention, in the telephone set according to the first aspect, the personal identification number input notifying means sends a voice message prompting the user to input a personal identification number to the sender. And As a result, in the case of this phone, the caller whose call is rejected listens to the voice message prompting the input of the personal identification number at the caller,
A person who knows the PIN can enter the PIN and call the called party. Therefore, for example, even if a person who has forgotten to enter a PIN is reminded to enter the PIN by listening to the voice message prompting the entry of the PIN at the caller, the calling side is called. be able to.

According to a third aspect of the present invention, in the telephone set according to the first or second aspect, the personal identification number discriminating means includes a signal indicating a personal identification number arriving from a caller, and a storage device. It is characterized in that it is determined whether or not the personal identification number data stored in advance matches the personal identification number data. Thus, in this telephone, when the signal indicating the personal identification number arriving from the caller matches the personal identification number data stored in the storage device in advance, the calling means starts calling on the called side. Since the personal identification number data is stored in the storage device as described above, for example, the personal identification number data can be set in a rewriteable mode. In this case, the user or the like can change the personal identification number data, which is convenient when it is necessary to change the personal identification number. It is desirable that the password can be set to the number of digits of the telephone number or less so that the user can easily use the password.

Further, according to the invention set forth in claim 4, in the telephone set according to any one of claims 1 to 3,
The calling means is characterized by calling by voice or display. This allows the telephone to call the user of the telephone by voice or display, so that the user can easily recognize that the telephone is being called. In this case, for example, a display means such as a liquid crystal display device displays a call of a telephone, or a calling means calls a telephone with a bell sound or the like, thereby calling a user of the telephone.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying a telephone according to the present invention will be described below with reference to the drawings. First, referring to FIG. 1, a schematic configuration of the telephone according to the embodiment will be described. The telephone 100 is a telephone corresponding to a so-called ID number display (caller telephone number display). In the ID number display service, ID number (source telephone number) information is added in a central office exchange (not shown) and displayed on the display device of the telephone set 100 on the receiving side.

The telephone 100 includes an incoming signal detecting means 101 for detecting an incoming signal transmitted from an exchange via a line L1 connected to a telephone line, and the incoming signal detecting means 101 closes the line. Line relay 1 for connection
03 is connected to the line L1 without passing through it. Also,
The incoming signal detecting means 101 is coupled to a source telephone number addition determining means 102, and the source telephone number adding determining means 102 is a signal transmitted from the exchange to the telephone 100 (hereinafter also referred to as an incoming signal). During the process, it is determined whether or not the telephone number data of the caller is added. In the service of the ID number display, the exchange exchanges the telephone number data of the transmission source with the telephone set 100 of the receiving side.
, The incoming signal transmitted from the exchange differs depending on the presence or absence of the telephone number data of the caller. Therefore, the source telephone number addition determining means 102 determines the difference of the incoming signal depending on the presence or absence of the telephone number data of the source, so that the telephone set 100 on the receiving side can determine whether or not the incoming call has the telephone number data of the source. Can be determined. As a result, when the call is not the call with the telephone number data of the caller, the call can be treated as an unidentified call of the caller and as a call that causes annoyance to the receiver.

The line relay 103 is connected to a source telephone number reading means 104. The source telephone number reading means 104 reads the source telephone number data added in the exchange when receiving a call. read. In the case of the ID number display service,
After the incoming signal detection means 101 detects the incoming signal, the line is closed by the operation of the line relay 103, so that the telephone number data of the caller reaches the caller's telephone number reading means 104. As a result, the caller telephone number reading means 104 can read the caller's telephone number data and confirm the identity of the caller. However, the source telephone number reading means 10
If the telephone number 4 cannot read the telephone number data of the caller for some reason, the caller cannot be known, and the telephone 100 can be treated as an incoming call that causes trouble to the receiver.

In addition, the source telephone number addition determining means 1
02 and the caller's telephone number reading means 104 are, for example, the display means 1 constituted by a liquid crystal display (LCD) or the like.
The display unit 105 displays various information such as a source telephone number in a manner described later under the control of the source telephone number addition determining unit 102 and the source telephone number reading unit 104. Can be displayed. Similarly, the source telephone number addition determining unit 102 and the source telephone number reading unit 104 are connected to a calling unit 106 including, for example, a ringer, a transmitter, and the like. Source telephone number addition determining means 10
2 and a caller's telephone can be called by a bell sound or the like under the control of the source telephone number reading means 104. Accordingly, when the display means 105 displays a telephone call, or when the call means 106 calls a telephone by a bell sound or the like, the display means 105 and the call means 106
Constitutes calling means for calling the called party.

The source telephone number addition determining means 1
02 and the source telephone number reading means 104 are connected to a password input request notifying means 107 composed of, for example, a voice synthesizer or the like. Under the control of the means 102 and the source telephone number reading means 104,
A voice message prompting the user to input a personal identification number by voice is sent to the sender.

Here, the source telephone number addition determining means 10
2 determines that the caller's telephone number data has not been added at the time of the incoming call,
7. A voice message prompting you to enter your PIN, for example, "Currently, for your convenience, we cannot accept it. For urgent business, enter your PIN as a tone signal or Please call to add a telephone number. "

Similarly, source telephone number reading means 10
4, when the telephone number data of the caller cannot be read, a voice message prompting the personal identification number input request notifying means 107 to input the personal identification number, for example,
"We cannot accept it at this time for your convenience. For urgent business, please input your PIN with a tone signal." It is desirable that an arbitrary number of digits less than the number of digits of the telephone number (usually about 4 digits) can be set so that the user can easily use the password. In this case, the user has previously notified the relatives, acquaintances, etc., who need to be contacted, so the relatives, acquaintances, etc. may depress the numeric keypad on the operation panel of the originating telephone as appropriate to enter the password. Just enter it.

A password identification means 109 is connected to the line relay 103. The password identification means 109 registers the password transmitted from the source by a tone signal in the telephone 100 in advance. It is determined whether or not the password matches the predetermined password data. Specifically, the password input request notifying means 107 sends the voice message (... Input the password as a tone signal) to the caller by voice.
09 indicates whether the tone signal indicating the personal identification number sent within a predetermined time thereafter matches the personal identification number data (for example, “4649” shown in FIG. 4) previously stored in a storage device (described later). Is determined. The password identification means 109 is further connected to the display means 105 and the call means 106, and displays various information such as the originating telephone number on the display means 105 under the control of each of the means. The moving means 106 can be called.

The line relay 103 is connected to a line opening / closing call switch (call SW) 110 for passing or blocking an audio signal on the telephone line. Password identification means 10
Under the control of 9 or the like, in addition to the handset (receiver), it is connected to a line L2 coupled to a voice transmission / reception portion including a hands-free microphone, a speaker (not shown), and the like. Therefore, during a call, the call switch 110 and the line relay 103 connect the line L1 and the line L2 to allow the voice signal on the telephone line to reach the voice transmission / reception portion, or the voice from the voice transmission / reception portion. Signals can flow over telephone lines. On the other hand, during a non-call,
0 indicates that the line L2 is disconnected from the line L1 under the control of the password identification means 109 or the like, so that the voice signal on the telephone line reaches the voice transmission / reception portion or the voice from the voice transmission / reception portion. Signals can be blocked from flowing through the telephone line.

Here, the source telephone number addition determining means 10
2. Regarding the source telephone number reading means 104, the password input request notifying means 107, and the password identification means 109, the CPU as the control means executes the flowchart shown in FIG. Fulfill. Therefore, the CPU includes a rewritable memory (hereinafter, referred to as a RAM) as a storage device for storing the data of the personal identification number and a read-only memory (hereinafter, referred to as a RAM) for storing a program corresponding to the flowchart.
ROM), and when executing a program, RA
M and ROM are used as appropriate. In the case where the personal identification number data is stored in the RAM, for example, the personal identification number data can be rewritten. When the personal identification number data is set to be rewritten as described above, the user can change the personal identification number data, which is convenient when it is necessary to change the personal identification number.

The operation of the telephone 100 configured as described above will be described with reference to the flowchart shown in FIG. First, when an incoming call arrives at the telephone set 100, the source telephone number addition determining means 102 determines whether or not the incoming telephone number data is added to the incoming signal (200).

Here, the source telephone number addition determining means 10
When it is determined that the caller's telephone number data is added to the incoming signal (200: YES), the line relay 103 automatically switches the line according to an instruction from the caller's telephone number addition determining means 102. To close (20
1) The source telephone number reading means 104 can read the telephone number data of the source.

At this time, the line is automatically closed by the telephone 10
Since 0 is for receiving the telephone number data of the caller, in the case of the ID number display service, the call charge is set so as not to be charged. During the automatic line closing, the call switch 110 is used only for reading the telephone number data of the caller.
Separates the voice transmission / reception part from the line.

Next, source telephone number reading means 104
Determines whether the telephone number data of the caller has been read (202). Here, if the caller telephone number reading means 104 determines that the telephone number data of the caller has been read (202: YES), the telephone set 100 does not need to reject the incoming call. The line relay 103 automatically releases the line once in response to an instruction from 104 (203). Here, the line is automatically released once (208) because the automatic line closing up to that point is limited to receiving the source number data and cannot be used for other purposes. Once the line is automatically released, the line is closed again to enable transmission and reception of a password input request notification and the like. afterwards,
The source telephone number reading means 104 sends the determined telephone number data to the display means 105, and causes the display means 105 to display the source telephone number (204). FIG. 3 shows a display example of the display means 105 at that time.
05 displays "Incoming call (Chaksin) and its source phone number (0123456789)". At the same time, the caller telephone number reading means 104 instructs the calling means 106 to start calling a ringing tone (2).
05).

Then, it is determined whether or not the receiver is off-hook (206).
06: NO), the display means 105 indicates that an incoming call is being displayed,
The ringing means 106 rings a ringing tone. Here, a person near the telephone set 100 notices the ringing tone, confirms the displayed caller's telephone number and turns off the receiver (206: YES), and the line relay 103 and the call switch 110 are closed. Since the line is closed (207), the state shifts to the talking state.

On the other hand, if the source telephone number data is added to the incoming signal, but the source telephone number reading means 104 cannot read the source telephone number data for some reason, the source telephone number reading means 104 determines this (202: NO), and the line relay 103 temporarily automatically opens the line once in response to an instruction from the caller telephone number reading means 104 (208). Here, the line is automatically released once (208) because the automatic line closing up to that point is limited to receiving the source number data and cannot be used for other purposes. Once the line is automatically released, the line is closed again to enable transmission and reception of a password input request notification and the like. afterwards,
In response to an instruction from the source telephone number reading means 104, the line relay 103 automatically closes the line once (209), and the password input request notifying means 107 outputs the voice prompting the source to input a predetermined password. The message is sent (210). The reason for this setting is that if the source telephone number reading means 104 cannot read the telephone number data of the source, the telephone 100 basically rejects the incoming call and sets a "mischief telephone" or the like. While preventing unwanted calls from being received by the user, in the case of an incoming call of a relative, acquaintance, or other person who needs to be contacted, the caller is notified to enter a predetermined password, and the caller This is because the display unit 105 and the calling unit 106 start calling after confirming that the signal indicating the predetermined password has arrived. The telephone number data of relatives and acquaintances is registered in a memory such as a RAM in advance, and even if the calling telephone number reading means 104 reads the calling telephone number, the telephone number registered in the memory is read. The data may be compared with the data, and if they do not match, the password input request notifying means 107 may send a voice message urging the sender to input a predetermined password.

If the caller's telephone number data is not added to the incoming signal, the caller's telephone number addition discriminating means 102 judges this (200: NO). , The line relay 103 automatically closes the line once (209),
The password input request notifying means 107 sends the voice message prompting the sender to input a predetermined password (21).
0). The reason for this setting is that when the telephone number data of the caller is not added, the telephone 100 basically rejects the incoming call and makes a call to the user such as a “mischief call” that is annoying to the user. While preventing incoming calls, relatives,
In the case of an incoming call of a person who needs to be contacted by an acquaintance or the like, since these people know the password, the sender is notified to input the predetermined password, and the source transmits the predetermined password. This is for starting the calling by the display means 105 and the call means 106 after confirming the arrival of the signal indicative of. In this case, unlike the case of receiving the caller's telephone number data, a call fee is charged, but in this state, the call switch 110 is still released.

Here, the user who listens to the voice message prompting the input of the personal identification number inputs the personal identification number at the transmission source, so that the transmission source outputs a tone signal indicating the personal identification number from the transmission source, and the exchange and the telephone. The call arrives at the called telephone 100 via the line. Then, the password identification means 109 determines whether the tone signal indicating the password transmitted within the predetermined time matches the password data (for example, “4649” (see FIG. 4)) stored in the RAM beforehand. It is determined whether or not it is (211).

A tone signal indicating a personal identification number and personal identification number data (for example, "464") stored in a RAM in advance.
9 ") (211: YES), the password identification means 109 sends a signal indicating that the password has arrived to the display means 105, and displays the signal (212). FIG. 5 shows a display example of the display means 105 at that time. The display means 105 of FIG. 5 displays "A call has been received (Chaksin) and a correct password has arrived (Chaksin Ansho Bangou OK)". I do. At the same time, the password identification means 109 instructs the calling means 106 to start calling a ring tone (213).

Then, it is determined whether or not the receiver is off-hook (214).
14: NO), the display means 105 indicates that an incoming call is being displayed,
The ringing means 106 rings a ringing tone. Here, a person near the telephone set 100 notices the ringing tone, confirms the displayed caller's telephone number, and off-hook the receiver (214: YES), the call switch 110 is closed, and the call state is set. Transition.

A tone signal indicating a password and a RAM
Password data (for example, "464
9 ") does not match (211: NO), the password identification means 109 does not transmit any signal to the display means 105 and sends an instruction to start calling to the calling means 106. Since there is no such thing, the incoming call is rejected. Thus, a person near the telephone 100 will not go off-hook on the handset of the telephone 100 for an incoming call. In this case, the password input request notifying means 107 may provide a voice message prompting the user to input a password if necessary, for example, "The input number is incorrect. Please send it to the sender. If a wrong password is entered a predetermined number of times, the line may be opened.

As is apparent from the above description, according to the invention of this embodiment, the source telephone number addition determining means 102 for determining whether or not the telephone number of the source is added, A source telephone number reading means 104 for determining the telephone number data; if the source telephone number is not added, or if the source telephone number data cannot be determined, In the telephone set 100 capable of rejecting the incoming call, a password input notifying means 107 for notifying the caller to input a predetermined code number, and indicating the code number from the caller. A code number discriminating means 109 for discriminating the arrival of the signal, and a caller who starts a call on the called side after confirming that the signal indicating the predetermined password has arrived. 106 and the display unit 105 and a (calling unit). Therefore, if the caller's telephone number data is not added or the caller's telephone number data cannot be determined, the caller is notified to enter a predetermined password, and the caller is notified. After confirming that the signal indicating the predetermined password has arrived from the beginning, it becomes possible to start the call on the called side.
Therefore, according to this telephone, it is possible to reliably reject a call of an incoming call whose source is not clear, and to reliably call a necessary incoming call.

It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various improvements and modifications can be made without departing from the gist of the present invention. For example,
The telephone of the above embodiment is equipped with an answering machine function,
When the correct password of FIG. 2 is not input (211:
NO), the answering machine function may be activated to record the voice of the caller, confirm the caller, and then go off-hook the receiver. In addition, a password input request notifying unit 107 according to another embodiment not only requests input of a password but also inputs a telephone number of a caller to a caller as necessary. May have a function of sending a message prompting the user. Further, the source telephone number reading means 104 has a function of reading telephone number data and the like transmitted from the source by a tone signal, if necessary, in addition to reading the telephone number data of the source added in the exchange. May be.

When a function of reading telephone number data or the like is provided, a tone signal indicating a password and a RAM
Even if the password data stored in the telephone 100 does not match, for example,
Can be called. That is, after the source telephone number input request notifying means sends a voice message prompting the input of the home telephone number of the source to the source, when the telephone number data is input at the source, The original telephone number reading means determines the telephone number data based on the tone signal input by the caller, and when the determined telephone number data matches the telephone number data of the telephone directory registered in the telephone, the display is performed. The means 105 sends and displays the determined telephone number and causes the calling means 106 to start calling on the called side. With such a function, it is necessary to input all the home telephone numbers, but a person who has forgotten the password can call the called party.

The telephone of the present invention is not limited to a telephone having only a telephone function, but may be used in a facsimile apparatus having a telephone function and a facsimile transmission / reception function. In addition to a copy function for reading the image information of the image and copying the read image information onto a recording sheet, it is used in a multi-function device having a printer function, a read-only function, and the like, and used in an apparatus having a computer function.
