Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key telephone terminal system and a method of transmitting a speed dial key of the key telephone terminal system.

[0002]

2. Description of the Related Art A key telephone terminal system accommodates a plurality of key telephone terminals and office lines so that an internal telephone call can be made between the key telephone terminals. Of these, a telephone system suitable for relatively small offices, etc., in which vacant office lines are captured and button telephone terminals that have requested external line connections are connected to external lines using the captured office lines is there.

[Prior Art 1] By the way, in the conventional key telephone terminal system, when the dial key of the key telephone terminal is operated at the time of making a call, a single key beep sound is transmitted to confirm that the dial key is pressed. It has a configuration. In addition, depending on the type of the key telephone terminal, an LCD (liquid crystal) display is provided as a display device, and a pressed dial number is displayed here.
You can visually check the telephone number you dialed.

[0004] Further, in a conventional key telephone terminal having a dial key, a protrusion is generally formed on a key of a "dial 5", which has an auxiliary meaning when a call is made by a blind touch and a visual sense. In a situation where it is difficult to confirm the dial key, for example, in a case of a dial operation in a dark environment or a case where a user with visual impairment performs a call operation, the number position of the dial key is assisted. .

[0005] Here, normally, when a call operation is performed (such as when a healthy person performs a dial operation), it is possible to visually confirm the dial key corresponding to the dial number to be depressed while depressing it. OK, and as mentioned above, LC
In the case of a button telephone terminal with a D display, since the dial number pressed visually can be confirmed from another viewpoint, the caller can perform a call operation while reconfirming the number dialed by himself. Being able to do so helps prevent false dialing.

However, in a case where a calling operation is performed in a situation where it is difficult to visually confirm the dial key, a single key beep sound for confirming that the dial key has been pressed and a dial key of the numeral "5" The dial operation must be performed using the projection formed on the key top as a guide. Therefore, there is a problem that the user may have anxiety during dial operation or may easily make an incorrect dial.

[Prior Art 2] In addition, the conventional key telephone terminal system shortens the registration of dial information (telephone number) of a frequent call destination in order to enable one-touch dialing of the frequent call destination. There are dial keys.

However, since abbreviated dial keys can freely register a destination, when one-touch dialing using the abbreviated dial key is attempted, which abbreviated dial key of the key telephone terminal is the destination is directly determined. I don't know.

In the case of a dial key, a projection is provided on the key top of the "5" dial key, so that the dial key can be confirmed. However, in the case of abbreviated dialing, it is difficult to confirm the destination. Therefore, for example, when a user with visual impairment performs a speed dial transmission operation, it assists in confirming a dial destination. However, in the case of the speed dial key, there is no clue as it is for a user with visual impairment.

Normally, when performing a speed dialing operation (such as when a healthy person performs a dialing operation), it is possible to visually confirm the corresponding dial key of the dial number to be pressed. Also, by specifying the destination on a piece of paper inserted in the name entry part corresponding to the speed dial key of the key telephone terminal, it is possible to confirm where the speed dial key is. You can confirm the dial contents sent by the speed dial key that you have sent, and you can perform outgoing operation,
Prevent wrong telephone calls.

However, even for a healthy person, it is difficult to obtain visual information in a dimly lit room or the like, and performing a call operation using abbreviated dial keys involves a risk of erroneous dialing.

[Prior Art 3] Conventionally, when a dial call is made from a key telephone terminal of a key telephone terminal system, in the case of a key telephone terminal provided with an LCD display, a caller is required to make a dial call. In the middle,
The pressed dial contents can be confirmed on the LCD display.

However, if a dial operation is mistaken during dialing, it is necessary to start dialing again from the beginning. You have to return to starting. For example,
If you dial "0123-457" while dialing "0123-456-7890", you should change only the incorrect dial "7" to dial "6". If you want to continue dialing while keeping the previous dialing, you have to suspend dialing and start dialing again from the beginning.

[0014] Even in the case of registration for abbreviated dialing, similarly, if an erroneous dialing is performed, it is necessary to restart the registration work from the beginning, and the same problem occurs.

[Prior Art 4] Further, in order to make a one-touch call in a conventional key telephone terminal system, information on a dial number to be transmitted may be registered in advance in a speed dial key. However, conventional systems have
Only one dialing destination information content can be registered in one speed dial key.

There are a limited number of flexible buttons (keys that can be used by setting desired functions of the user) on the telephone terminal that can be used for the speed dial keys.
There is a limit to the number of calls that can be made with one touch, and a special number must be pressed to confirm the registered contents of the shortcut keys.

[0017]

[Problem 1] Problems to be solved by the prior art 1 will be considered.

When dialing operation is performed in a situation where it is difficult to visually confirm the dial key, a single key beep sound for confirming that the dial key has been pressed and a dial key of "dial 5" are used. Dial operation must be performed using the projection formed on the keytop as a guide.

For this reason, there is a problem that the user does not know what the contents of the dial operation are, and feels uneasy about the dial operation, and easily makes an erroneous dial.

[Problem 2] The problem of the prior art 2 will be considered.

In the conventional key telephone terminal system, dial number information of a dial destination can be freely registered in the speed dial key. Therefore, there is no clue as to which speed dial key is registered in which dial destination.
The outgoing dial number information by the operation of the speed dial key is displayed on the display, but the visually impaired person cannot see it, so that the dial destination by the operated speed dial key cannot be confirmed.

In the case of the dial key, the position can be known by the projection formed on the dial key top of the "dial 5", and the user can set the key to the home position and grasp the position of the other keys, so that the user can feel the sense. You can check which dial key you operated.

However, in the case of the speed dial key, since there is no clue, it is difficult to confirm the call destination. For example, even if a user with visual impairment wants to perform the speed dial call operation, there is a risk of erroneous operation. There is a problem that there is. Therefore, there is a demand for the development of a mechanism that assists in confirming a dial destination when performing a calling operation using abbreviated dial keys.

[Problem 3] The problem of the prior art 3 will be considered. Conventionally, when dialing from a key telephone terminal of a key telephone terminal system,
In the case of a button telephone terminal provided with an LCD display,
The caller changes the pressed dial to L during dialing.
It can be confirmed by a CD display. However, if a dial key is accidentally pressed during dialing, it is necessary to restart the dialing operation from the beginning.

There is no partial cancellation. Therefore, for example, when "0123-456-7890" is to be dialed and "0123-457" is dialed, there is a problem that the dialing operation must be restarted from the beginning.

Also, when registering to the speed dial key, similarly, if an incorrect dial is performed, it is necessary to restart the registration work from the beginning, and there is a problem that the operation must be restarted from the beginning.

[Problem 4] The problem of the prior art 4 will be considered. In the key telephone terminal system, the number of the shortcut keys provided in the telephone terminal is limited due to a space relationship. On the other hand, the user has a wide range of call destinations, and there are many call destinations with high frequency. Although there is a registration method of assigning with “*” + “number”, it can be selected by two touch (“*” key operation and “one digit” key operation) or three touch (“*” key There are many key operations such as selection by operation and key operation of "numerical characters", and it is incomparable to the convenience of using speed dial keys, which are dedicated keys that can be dialed with one touch .

However, in the conventional speed dial key, only one dial destination can be assigned to one key, and the benefit of the speed dial key cannot be sufficiently obtained. In addition, there is a problem that it is extremely inconvenient for the user, for example, a special number operation is required to know the setting contents.

Therefore, a first object of the present invention is to provide a button telephone terminal system capable of notifying the contents of buttons (keys) operated at the time of dial operation by voice so as to suppress erroneous dialing. It is in.

It is a second object of the present invention to provide a key telephone terminal system having a function of notifying the contents of a dial sent by a speed dial key by voice.

Further, a third object of the present invention is to correct only a mistake made when a dial input is made in the middle of the abbreviated dialing operation. It is another object of the present invention to provide a button telephone terminal system and a method for transmitting abbreviated dial keys of the key telephone terminal system, which enable a dial to be corrected for the wrong part.

A fourth object of the present invention is to register dial information of a plurality of dial destinations in one speed dial key, to sequentially select registered contents one by one, and to dial the selected dial destination. Information is displayed on the LCD display, and a function of automatically dialing the indicated dial destination by going off-hook in this state is provided. An object of the present invention is to provide a button telephone terminal system in which a dial destination is registered by one-touch dialing and made usable.

[0033]

In order to achieve the above object, the present invention is configured as follows. That is, [1] First, in order to achieve the first object, in a key telephone terminal system, at least a dial key, an input means for inputting a dial number, and a dial input by the input means Voice synthesizing means for synthesizing voice corresponding to the number and outputting it as a voice signal; selection setting means for selectively setting whether or not to output a voice corresponding to the dial number input by the input means; and setting of the selection setting means Means for outputting a voice signal output by the voice synthesizing means when the content is available for voice output.

The key telephone terminal system having such a configuration has selection setting means for selecting and setting whether or not to output a voice corresponding to the input dial number. When a dial number or the like is input by the input means, voice synthesis is performed. The means synthesizes voice corresponding to the input dial number and outputs it as a voice signal, and the voice output means is output by the voice synthesis means when the selection setting means is set to output voice. Output the audio signal.

Therefore, even in a situation where it is difficult to visually confirm the dial key, for example, when a user of the key telephone terminal system includes a user with visual impairment,
By setting the voice output corresponding to the entered dial number to voice when operating the dial keys, it is possible to notify the user of the input of the dial number by voice. It is possible to perform while checking. Therefore, it is possible to provide a key telephone terminal system that can be expected to eliminate anxiety (providing a sense of security) at the time of dial operation in a situation where it is difficult to visually confirm a dial key and to expect an effect of preventing erroneous dialing.

[2] Secondly, in order to achieve the second object, in the key telephone terminal system, a speed dial key in which dial number information is registered and a dial number registered in the speed dial key Voice synthesis means for synthesizing the corresponding voice and outputting it as a voice signal; selection setting means for selectively setting whether or not to output a voice based on the voice signal obtained by the voice synthesis means; Audio output means for outputting an audio signal from the audio synthesis means as audio when output is possible.

Further, a function is provided for transmitting a call to a speed dial destination by the speed dial key operation by off-hook operation of the telephone terminal.

According to the present invention, when the speed dial key of the key telephone terminal is operated, the dial number registered in the speed dial key is output as voice to the key telephone terminal (for example, "0425 ..."). . ", The button telephone terminal utters" zero, yon, ni, go, ... ", for example, a visual speed dial key. When a speed dial transmission operation is performed in a situation where it is difficult to confirm the dial, the dial to be transmitted can be confirmed by voice. Then, after the confirmation, if the user goes off-hook, for example, by lifting the receiver, it is possible to make a call to the shortened registered dial destination, so that the effect of preventing a wrong telephone call can be expected.

[3] Thirdly, in order to achieve the third object, in the key telephone terminal system, an input means for inputting dial number information such as a telephone number, and an input means for inputting the dial number information. Memory means for holding the contents of the dial number information, display means for displaying the contents held in the memory means, and cancellation for sequentially canceling the dial number information held in the memory means one digit at a time starting from the latest input digit Key input means and means for transmitting information on the dial number held in the memory means are provided.

According to this configuration, information on the dialed number that has been dialed is held in the memory means and displayed on the display means. The contents held in the memory means can be canceled one digit at a time by depressing the cancel key. Therefore, if you make an erroneous dial operation during dialing, you can cancel the wrong dial number by pressing the cancel key and make a partial correction to correct the dial number.
There is no need to redo the dial from the beginning, and erroneous dialing can be corrected with the minimum necessary operations.

As a result, it is possible to provide a key telephone terminal system in which the effect of preventing erroneous dialing can be expected.

[4] Fourth, in order to achieve the fourth object, in the key telephone terminal system, a speed dial key capable of registering a plurality of dial destination telephone numbers for each key, For each operation, the contents of a plurality of dial information registered in the speed dial key are sequentially
Control means for selecting one dial destination unit; display means for displaying information on the dial destination selected by the control means;
Means for capturing an office line by an off-hook operation of the key telephone terminal and transmitting dial number information displayed on the display means to the office line.

In such a key telephone terminal system, dial information of a plurality of dial destinations can be registered in one speed dial key. Such abbreviated dial keys select dial contents registered in the abbreviated dial key sequentially for each key operation in units of one dial destination, and display the information of the selected dial destination on a display means. , The office line can be captured by the off-hook operation, and the information of the dial number displayed on the display means can be transmitted to the office line.

As described above, since dial number information of a plurality of dial destinations can be registered in one speed dial key,
The limited number of flexible buttons can be used effectively, and the office line can be captured by off-hook operation and the dial number information displayed on the display means can be sent to the office line. A key telephone terminal system can be provided.

Further, according to the present invention, a plurality of dials can be registered with one abbreviated key, and when the abbreviated key is operated, the registered contents of the abbreviated key pressed are displayed on the LCD display and each time the abbreviated key is pressed, it is sequentially displayed. Since the telephone number of the next registered content is scroll-displayed, the operability is good.

Next, a specific example of the operation of the present system having such a configuration will be described with reference to the flowchart shown in FIG.

Now, consider a case where the user of the extension telephone 1-1 tries to talk to an outside line. In order to talk to an outside line, it is necessary to capture the office line, so that the user of the extension phone 1-1 presses the office line key 14c. Then, the press information of the line key 14c is
The signal is transmitted to the central processing unit (CC) 7 via the line circuit (LC) 2-1 and the control data bus line 6 (step S501). Thereby, the central processing unit (CC) 7
Of the office line trunks (TRK) 4-1 to 4-m, a free office line trunk is checked, and if there is an available office line trunk, one of the office line trunks is controlled, and the extension telephone 1-1 is controlled. To secure for. And the central processing unit (CC) 7
The tone generation circuit 9 is controlled to generate a tone signal indicating that the line is secured, and the tone signal is controlled to be transmitted to the extension telephone 1-1 via the communication network (SW) 5. The user listens to this sound via the handset 11 or the speaker 16 and knows that it is possible to make a call to an outside line.

Next, it is assumed that the user of the extension telephone 1-1 operates the extension telephone 1-1 and, for example, presses the dial key 13 thereof. Here, for example, if the key of the dial “1” is pressed, this key press information is transmitted to the central processing unit (CC) 7 via the line circuit (LC) 2-1 and the control data bus line 6. (Steps S502 and S503).

If the user presses a key other than the dial key 13 in step S503, the process proceeds to step S508, where the central processing unit (CC) 7

As described above, when a key other than the dial key is erroneously operated in a state where the dial operation is required, the erroneous operation is notified by outputting a key beep sound to the extension telephone 1-1. be able to.

The dial key press information “1” is given to the central processing unit (CC) 7 via the line circuit (LC) 2-1 and the control data bus line 6. Then, the central processing unit (CC) 7 sets the extension telephone 1 in the MF back tone presence / absence individual setting table (FIG. 4) in the storage device (MEM) 8.
It is checked whether or not the setting corresponding to -1 is a setting with a tone (step S504). If there is no tone, the process proceeds to step S506.

If there is a tone in step S504, the central processing unit (CC) 7 connects the extension telephone 1-1 and the tone generating circuit 9 via the communication network (SW) 5 and the line circuit (LC) 2-1. Connect, extension phone 1-
For example, the MF back tone corresponding to the key number of the pressed dial key (the key of the dial "1" in this example) is output to the extension telephone 1-1 (step S50).
5), and proceed to step S506.

Next, the central processing unit (CC) 7 determines whether the setting corresponding to the extension telephone 1-1 in the voice output presence / absence individual setting table (FIG. 3) in the storage device (MEM) 8 is a setting with voice output. It is checked whether or not it is (step S506). If there is no audio output, the process ends.

On the other hand, if the result of the check in step S506 is that there is audio output, the central processing unit (CC) 7
The extension telephone 1-1 and the voice synthesis circuit 10 are connected via the communication path network (SW) 5 and the line circuit (LC) 2-1. In the case of this example, the dial "1" key)
Is controlled to generate an audio output (“Ichi”) corresponding to the audio output (“Ichi”) from the audio synthesis circuit 10.
Is generated and output to the extension telephone 1-1 (step S507), and the process ends.

Here, as an example, the setting of the presence or absence of the output of the MF back tone and the setting of the presence or absence of the audio output corresponding to the dial number for each terminal has been described.
Furthermore, instead of individual settings for each terminal, settings can be changed collectively for the entire key telephone terminal system.

As described above, according to the invention shown in this embodiment, when the dial key of the key telephone terminal is operated, the voice corresponding to the dialed number (for example, when the key of the dial "1" is pressed, "("Ichi" is uttered by the phone terminal)) to the key phone terminal.
For example, when performing a call operation in a situation where it is difficult to visually confirm the dial key, input of the dial number is
Since it can be performed while reconfirming one digit at a time by voice, there is no feeling of anxiety at the time of dial operation, and the effect of preventing incorrect dialing can be expected.

The central processing unit (CC) 7 temporarily stores dial operation information input from the extension telephone 1-1 in the storage device (MEM) 8 within a predetermined time, and corresponds to the telephone number of the call destination. When all dial key information has been fetched or a predetermined time has elapsed, the stored dial operation information is transmitted as a dial number signal to an office trunk, and received by the public via the office line. On the network side, a call is made to the destination of the dialed number and called.

In the above, the information of the operated dial key by the dial key operation is audibly uttered to notify the user, thereby preventing the erroneous operation of the dial operation. There is also a dial function, and if you can check the contents of speed dial keys, operability will be improved. Therefore, an embodiment in which the contents of the speed dial key can be confirmed by voice will be described next as a second embodiment.

(Second Embodiment) An outline of a second embodiment of the present invention will be described with reference to the drawings.

FIG. 6 shows the configuration of the key telephone terminal system, and FIG. 7 shows the appearance of the key telephone terminal.

The configuration of the key telephone terminal system in FIG. 6 is basically the same as that of the key telephone terminal system in the first embodiment.
1-n, line circuits (LC) 2-1 to 2-n, office line 3-
1, to 3-m, office trunk (TRK) 4-1 to 4-
m, communication path network (SW) 5, control data bus line 6, central processing unit (CC) 7, storage device (MEM)
8A, a tone generation circuit 9 and a speech synthesis circuit 10,
These are basically the same as the components having the same reference numerals and the same names in the first embodiment.

In the key telephone terminal system of this embodiment, the function of the storage device (MEM) 8A is as follows.
In addition to storing various control programs and various tables of the central processing unit (CC) 7 and data such as various set function contents, the central processing unit (CC) 7 also has a function for holding a database and message data. The storage device (MEM) 8A has a speed dial key voice output presence / absence individual setting table as shown in FIG. 8 so that the presence / absence of speed dial key voice output can be individually set for each extension. .

The extension telephones 1-1 and 1-n are, for example,
As shown in FIG. 7, a handset 11 for a call and its hook mechanism 12, a dial key 13 for a dial operation, an LCD (liquid crystal) display 15 as a display device, a speaker 16 for voice loudspeaker output, an allocation. Extension DN key 14a for answering the incoming call to the extension being set
Key 14 which is a switch for voice calls
b, a line key 14c for capturing a line, abbreviated dial keys 14d, 14e, 14f, and the like.

Speed dial keys 14d, 14e, 14f
Can be assigned dial number information of a specific dial destination set by the user, and the assigned dial information is stored in a storage device (MEM) 8A corresponding to the key code of the speed dial key and for each extension. Let it be.

When the central processing unit (CC) 7 receives the information of the speed dial key from the off-hook extension telephone, the central processing unit (CC) 7 corresponds to the key code of the speed dial key stored in the storage device (MEM) 8A for each extension. , Dial number information is read out, and the dial number information is transmitted to the office line, so that a call can be made with the dial number of the target dial destination by one-touch only by pressing the speed dial key. .

Next, the operation of the present system having such a configuration will be described. Now, consider a scene in which the user of the extension telephone 1-1 tries to talk to an outside line.

In the case of the configuration of this embodiment, the extension phone 1-1
The user of the extension phone 1-1 operates the speed dial key of the extension phone 1-1 without off-hook operation of the extension phone 1-1, thereby taking in the dial number information assigned to the speed dial key, and obtaining the number content by voice. By listening to the reading aloud and then performing an off-hook operation, a call can be made to the destination of the number.

Now, when the user wants to make a call, the speed dial key 14d of the extension telephone 1-1 (see FIG. 7).
It is assumed that is pressed. Then, the key press information is output from the extension phone 1-1, and the line circuit (LC) 2-1 is output.
Central processing unit (CC) via control data bus line 6
It is conveyed to 7.

The central processing unit (CC) 7 receives this information and recognizes which key has been pressed. At this time, if any key other than the speed dial key is pressed,
This key press information is output from the extension phone 1-1,
This is transmitted to the central processing unit (CC) 7 via the line circuit (LC) 2-1 and the control data bus line 6. The central processing unit (CC) 7 recognizes what the transmitted key press information is.

When the central processing unit (CC) 7 recognizes that it is a key other than the speed dial key from the contents of the key press information, it controls the tone generation circuit 9 to output a key beep sound. Then, since the central processing unit (CC) 7 controls the key beep output from the tone generation circuit 9 to be given to the extension telephone 1-1, the extension telephone 1-1 receiving the key beep sounds the handset 1
1 or the speaker 16 to output a key beep sound, and the user who listens to this will know aurally that a key other than the speed dial key has been operated.

On the other hand, if the key press information from extension telephone 1-1 is press information of a speed dial key, central processing unit (CC) 7 recognizes which speed dial key press information. . Then, it knows that the recognized speed dial key is the speed dial key 14d, and reads out the dial number information assigned to the speed dial key 14d from the storage device (MEM) 8A.

The central processing unit (CC) 7 stores the read dial number information in its own buffer.

Next, the central processing unit (CC) 7 refers to the individual setting table (FIG. 8) for the presence / absence of the voice output for abbreviated dial keys in the storage device (MEM) 8A, and corresponds to the extension telephone 1-1 in the table. Check whether the setting to be performed is a setting with tone. If the result of the check indicates that there is no audio output, the process ends.

When the setting of the individual setting table for the voice output presence / absence for the abbreviated dial key is voice output, the central processing unit (CC) 7 connects the extension telephone 1-1 and the voice synthesis circuit 10 to the communication network (SW) 5, Line circuit (LC) 2
−1, and reads out and provides the dial number information in the buffer to the voice synthesis circuit 10 to cause the voice synthesis circuit 10 to output a voice signal corresponding to the dial number information by voice synthesis. , And outputs this voice signal to the extension telephone 1-1.

Therefore, the dial number (dial “0”, “4”) set to the pressed speed dial key
Audio output ("zero") corresponding to "5" ...
..) Are output to the extension phone 1-1, and the user listens to this voice to determine what telephone number is the key registered in the speed dial. It can be confirmed by ear.

After confirming that the user is the intended dial destination, the user performs an off-hook operation such as picking up the handset 11, and upon detecting this operation, the central processing unit (CC) 7 detects the operation and the central office trunk (TRK) 4-. 1, to 4-
In step m, a vacant trunk is searched, and the read dial number information held in the buffer is transmitted to the vacant trunk line trunk (TRK) to make a call.

As described above, the user of the extension telephone operates the speed dial key of the extension telephone without off-hook operation of the extension telephone, thereby taking in the dial number information assigned to the speed dial key, and using the voice. If you listen to the reading of the number and then perform off-hook operation, you can make a call to the other party of the number, so simply pressing the speed dial key can check the contents by voice and call if there is no error It is possible to make a call with the dial number of the target dial destination with one touch without knowing which speed dial key has the target dial destination registered.

Here, the setting of the presence / absence of audio output corresponding to the abbreviated dial key for each terminal has been described as an example. However, not individual setting for each terminal, but the entire key telephone terminal system It is also possible to change settings in a batch.

In the foregoing, the extension telephone system has been described in which it is possible to make a call after ascertaining whether or not a correct key operation has been performed by voice. By the way, generally, when dialing is performed incorrectly when dialing, it is necessary to perform on-hook operation, clear all operations, and perform dialing again from the beginning. Now, the telephone number has about 10 digits in the case of a public network, and more digits when a sub-address is required or when using a telephone line of a company other than NTT (Nippon Telegraph and Telephone Corporation) or international calls. Since the dial number is added, it is very burdensome for the user to have to redo the dial operation from the beginning.

An embodiment capable of reducing this will be described next as a third embodiment.

(Third Embodiment) In the third embodiment,
An example of a button telephone terminal system that enables dial correction during dialing will be described.

In this case, even if an erroneous dial is performed during dialing of the key telephone terminal or during dial registration to abbreviated dialing or the like, pressing the cancel key prepared for the key telephone terminal can be performed. , So that only the wrong digit of the dialed number can be canceled and corrected to the correct dialed number, eliminating the need to start over from the beginning and correcting incorrect dialing with the minimum necessary operations It is an example.

Hereinafter, an outline of a third embodiment of the present invention will be described with reference to the drawings.

FIG. 9 is a diagram showing a system configuration example of a key telephone terminal system according to the third embodiment of the present invention.
In the figure, reference numeral 200 denotes a key telephone terminal, which corresponds to the extension telephones 1-1 and 1-n in the first and second embodiments. Further, reference numeral 100 denotes a key telephone main unit, and FIG.
Is a small-sized configuration, and may be substantially the same as the configuration in FIG.

The key telephone terminal 200 is connected to the key telephone main unit 100. The key telephone terminal 200 has a handset 211 for performing a telephone call and a calling operation, and 12 telephone numbers (“0” to “9”, “*”,
“#”) Dial key 212, L which is a display for confirming input contents by dialed keys
A CD display 213, a speed dial key 214 in which speed dials are registered, and a cancel key 215 for correcting a dial when an incorrect dial is made are provided. Reference numeral 216 denotes a speaker key for instructing a loudspeaker call. Note that the key telephone terminal 200 has a memory, and has a function of storing dial information input by operating the dial key 212 in the memory (dial information temporary holding function). This memory is stored in the key telephone main unit 10.
Alternatively, a configuration may be adopted in which a part of the storage device (MEM) 8 is used.

In this system, dial key 2
There is a control function that stores the dial information input by operating the key 12 in the memory, but the latest dial information stored can be canceled one digit at a time each time the cancel key 215 is operated.

FIG. 10 shows an example of an operation at the time of erroneous dialing and dial information held by the dial information temporary holding function in the dial accumulation memory (or the storage device (MEM) 8 of the key telephone main unit 100) in the key telephone terminal 200. It represents the transition of the change. Here, an example is described in which an operation is performed when a caller makes an erroneous dial while trying to dial “0123-456-7890”. A procedure for correcting a dial when an erroneous dial is performed using this will be described below.

[Processing 1] When the caller originally dialed 6 when dialing the seventh digit,
Suppose you dial "7". As a result, LC
The D-display 213 displays “0123457” and the held dial information content, and the dial storage memory in the key telephone terminal 200 (or the storage device (MEM) 8 of the key telephone main unit 100) similarly stores “0123457”. "
Is accumulated.

[Processing 2] The sender who noticed the error is 7
Cancel key 2 to modify digit “7” to “6”
Press 15. Thereby, the dial storage memory (or the storage device (MEM) of the key telephone main unit 100)
The dial information stored in the seventh digit of 8) is deleted, and the stored content becomes “012345”. Similarly, the LCD display 213 also displays "012345" to notify the sender
Notifies that the digit dial has been deleted.

[Processing 3] The caller who recognizes that the dial in the seventh digit has been deleted correctly dials “6”. Thereby, in the key telephone terminal 200, “6” is stored in the seventh digit of the dial storage memory (or, alternatively,
"6" is stored in the seventh digit of the storage dial information of the storage device (MEM) 8 of the key telephone main unit 100).
The stored content is “0123456”.

Similarly, “0123” is displayed on the LCD display 213.
456 "is displayed, and the caller is notified of the correct dialing.

[Processing 4] Similarly, if the remaining numbers are similarly dialed, the dial storage memory (or the storage device (MEM) 8 of the key telephone main unit 100)
, Dial information having a content of “01234567890” is stored, and “01234” is also displayed on the LCD display 213.
567890 "is displayed.

[Processing 5] The caller performs an off-hook operation or a call operation using the speaker key 216 or the like. In the key telephone terminal 200, the data stored in the dial storage memory (or the storage device (MEM) 8 of the key telephone device 100) is stored in a central processing unit (CC) (shown in FIG. )). Here, when the caller performs the abbreviated registration operation, the abbreviated dial registration for the abbreviated dial key 214 is also possible.

As described above, the cancel key which can be operated one character at a time is provided, and the dial information contents are buffered in the memory.
The buffered dialing information can be canceled one digit at a time by operating the cancel key, so if you make a mistake while dialing, or if you are registering a speed dial, When a dial input is mistaken, it is possible to correct an erroneous dial with a minimum necessary operation without redoing the dial from the beginning.

As described above, it is possible to make a dial correction during dialing to the key telephone terminal system.
An example has been shown in which the provision of a character cancel operation function enables correction of an erroneous dial with the minimum necessary operation without redoing the dial from the beginning.

In the key telephone terminal system, the number of the shortcut keys provided in the telephone terminal is limited due to space relations. On the other hand, the user has a wide range of call destinations, and there are many call destinations with high frequency. Although there is a registration method that assigns “*” + “number”, it can be selected by two-touch (“*” key operation and “numerical” one-character key operation) or three-touch (“*” key There are many key operations such as selection by operation and key operation of “numerical characters”, and it is incomparable to the convenience of using speed dial keys, which are dedicated keys that can be dialed with one touch .

However, in the conventional speed dial key, only one dial destination can be assigned to one key, and the benefit of the speed dial key cannot be sufficiently obtained.

Then, such a drawback is solved next, and
A fourth embodiment will be described as an embodiment in which a plurality of speed dial destinations are registered for one speed dial key so that the user can easily use one touch dial while enjoying the convenience of one-touch dialing.

(Fourth Embodiment) In the fourth embodiment, a plurality of speed dials are registered in a speed key, and the registered content is set to L.

The dial number of the desired call destination is registered in the shortcut key of the key telephone terminal 200 connected to “0”. In the present invention, 1
Since a plurality of dials can be registered in one abbreviated key, for example, dials of the same person such as a home, a work place, and a mobile phone can be collectively registered in the same abbreviated key.

When a speed dial key is pressed from the vacant button telephone terminal 200, the content of one type of speed dial registered in the speed dial key is selected and controlled to be buffered in the memory. Then, the buffered information content of the speed dial is sent to the LCD display and controlled to be displayed there.

Thereafter, each time the speed dial key is pressed, the contents of a plurality of speed dials registered in the key are sequentially selected, the latest selected one is buffered, and the speed dial is displayed on the LCD display. The content of the selected and buffered speed dial is displayed each time the key is pressed, so that the content of the speed dial is scrolled and displayed each time the speed dial key is pressed.

Then, when an off-hook operation is performed in a state where the dial to be transmitted is displayed, the information is sent to the key telephone main unit 100, and the contents of the buffered abbreviated dial are given to the key telephone. The telephone main unit 100 automatically captures a vacant office line out of the office lines accommodated in the key telephone main unit 100 and buffers the given office line to a given speed dial. The information content is transmitted to the office line, and the process ends.

That is, the user presses the speed dial key of the key telephone terminal 200 to select a desired dial destination number.
The information of the abbreviated dial being displayed on the LCD display of 00 is transmitted to the central office and a call is made to call the other party.
