DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multifunctional telephone in which the function of a one-touch dial button is extended by further adding another function to a one-touch dial button capable of calling a dial number by a single push-button operation. .

[0002]

2. Description of the Related Art As telephones have become more multifunctional, there is a feeling that speed dials and one-touch dials have already been established as general functions. By the way, the abbreviated dialing enables the calling of a registered dial number by a combined push button operation of a "abbreviated" button and dial buttons (1 to 9, 0). The one-touch dial enables a registered dial number to be called by a single push-button operation (one-touch operation) of a “one-touch dial” button.

On the other hand, a typical example of such a multi-functional telephone is a so-called cordless answering machine. This cordless answering machine has various function buttons according to a button telephone function (so-called cordless function) between parent and child units in a so-called cordless telephone or various function buttons according to an answering machine function (so-called answering machine function and answering machine function). It has. Therefore, the cordless answering machine with such a multi-function has a limited space in which various types of function buttons corresponding to the telephone function, cordless function, and answering machine function described later, including the dial buttons (1 to 9,0), are limited. Because they are densely arranged inside, there is a risk that not only the appearance is complicated but also an erroneous operation or confusion is caused in actual operation.

The following are typical function buttons mounted on the cordless answering machine described above. (Cordless function) (1) “Call by slave unit” button For example, slave units 1 to 4 can be individually called,
Hold a mutual conversation like an intercom with the master unit. (Answering function) (2) "Reply message recording" button In addition to recording the user's own message, reads out the fixed message built into the telephone and records it. (3) "Answering" button Starts the answering machine function. (4) Answering machine transfer button Notifies that the answering machine has been entered to a telephone or pager on the go. (5) "Message playback" button Plays the message of the other party recorded. (6) Recorder operation buttons These are the "PLAY (playback)" button, "STOP (stop)" button, "REW (rewind)" button, and "FF (fast forward)" button. The player performs playback, stop, rewind, and fast forward operations on a recorder (not shown). (7) “Time confirmation setting” button Sets the clock for automatically recording the recording start time of the other party's message in answering machine and confirms the set time. (8) "Silent answering machine" button All ringing and telephone sounds are cut, and the answering machine function responds. (Telephone function) (9) "Hold" button Even if you return the handset (slave), the call is not disconnected (the incoming call is put on hold) and an IC melody is played. (10) "Redial" button Remembers the last dialed number and redials automatically. (11) “Catch (flash)” button This button is a catch-phone service compatible button of NTT Corporation, and switches with one touch when receiving a call waiting. (12) "On-hook" button Dial without holding the handset, confirm that the telephone is connected, pick up the handset, and speak. (13) "Abbreviated" button A dial number registered by the combination operation of the abbreviated button and the dial buttons (1 to 9, 0) is called. (14) “One-touch dial” button Calls the registered dial number by one operation (one-touch operation). (15) "Intercom" button If a terminal box (not shown) is connected, the handset will respond to the intercom. (16) “Speakerphone” button A so-called hands-free function that plays a ringtone (the voice of the other party) from the speaker while the receiver is left, and sends it to the other party using a separately provided microphone (not shown). I do.

[0005]

The problems to be solved by the present invention mainly include the following problems (1) and (2).
was there. Problem (1) In order to arrange the above various types of function buttons in a limited space of a cordless answering machine, a combination of button functions is being performed. That is, the compounding of the button function means that two functions can be alternately read by one button. For example, the on-hook function and the hold function are alternately read by one “on-hook / hold” button. .
By combining such button functions, the number of buttons has been reduced without reducing the number of functions.

The on-hook function (the function of picking up the telephone after confirming that the telephone is connected) and the holding function (the telephone is returned even if the receiver is returned) are alternately read out by operating the "on-hook / hold" button. Function that cannot be cut off). Therefore, after the "on-hook / hold" button is operated to put the phone into the hold state, the receiver is not released from the telephone body when the handset is returned, so the hold state is checked by turning on the "on-hook / hold" button or the like. Unless otherwise, there is a risk that a normal missed call state (a state in which no call is received) may be erroneously recognized (for example, "on-hook /
Even if the `` hold '' button is lit to notify the user of the hold, if another function button is lit, etc., a user who is not accustomed to handling such a cordless answering machine will not be able to reliably recognize this hold state. Hard to say).

As a result of this misrecognition, "on-hook / hold"
If a call operation is started by operating the “abbreviation” button while an incoming call is being held by operating a button, there is a problem that the held incoming call is disconnected. As described above, by combining two functions into one button, the number of buttons is reduced to half, and a new function is added to a limited space of the telephone. At that time, there is a possibility that a large number of the above-mentioned operational confusions due to the compounding of the buttons may newly occur.

Problem (2) There are almost no cases in which the user uses all of the many functions described above, and some users have buttons that are not used at all. Therefore, there has been a demand for a telephone having only the functions required by the user.

The object of the present invention is to solve such problems (1),
(2) can be solved, and a function button conventionally used as a "one-touch dial" button is replaced with a function other than a dial number (for example, a "call by handset" function, an "extension" button 2bb described later). It is an object of the present invention to provide a multi-function telephone capable of newly registering a function obtained by operating the function, and assigning only a function required by a user to a function button on the telephone. .

[0010]

In order to solve the above-mentioned problems, the present invention provides at least a plurality of dial number designations.
Button, one-touch dial button, registration start / end button
Button, first registration button, second registration button, and other devices
Input operation unit having a function button and operation control in the telephone

The RESET button 2zz cancels the input operation by all the function buttons or the dial buttons on the input operation unit 2 described above.

The control unit 3 is provided with the various buttons described above.
By operating (1) to (33), an operation signal output from the input operation unit 2 is supplied. Then, it is determined whether this operation signal is an input of a cordless function, an answering machine function, a telephone function, or a dial number, and necessary operation control is performed over the respective parts of the multi-function telephone 1 according to this determination ( The operation up to this point is the same as the operation of the cordless answering machine described above, and the telephone number data registration processing of the one-touch dial when registering the telephone number in the one-touch dial is the same as before.

In addition to the above operations, the control unit 3 determines that registration is to be started by operating the "short / register" button 2ed, as described later, and thereafter, the one-touch dial button ("OD1") To operate any one of the buttons “5” to “OD5”.
Button 2ha, "extension" button 2bb, other function buttons 2ba, 2bc, 2bd, 2cb, 2cc, 2c
It is determined that any one of the buttons d, 2fd, 2gd, and 2hd is operated, and thereafter, the dial number designation buttons (“1” to “9”, “0”) are operated and the one-touch dial button is set. A function number corresponding to a desired function to be registered (for example, a function number coded by a two-digit number, and the function number “0” of the “reservation” button 2ba
Function numbers "02" of the "1" and "extension" buttons 2bb, and the function numbers corresponding to the respective function buttons are as follows. The "doorphone" button 2bc is "03", the "absence" button 2bd is "04", the "record" button 2cb is "05", and "message".
The button 2cc is “06”, the “message playback” button 2cd is “07”, the “flash” button 2fd is “08”,
The “redial / pause” button 2gd determines to input “09”, and the “on-hook / hold” button 2hd determines “10”). After that, the “shortening / registering” button 2e is determined.
A desired function is registered in the one-touch dial button by controlling a series of registration operations for determining that the registration is completed by operating d again (an extended function data registration process for one-touch dial described later).

When adding a function to be newly registered to the one-touch dial, the control unit 3 executes a code corresponding to each of the above-described functions that can be newly registered (registered in order to identify that this is an additional function registration). Determining the above-mentioned function numbers coded with symbols such as “*”, “#”, “A”, “B”, “C”, “D” and two-digit numbers added at the beginning of the data) The function-to-function number conversion table created by the internal or external memory (RA
M) is essential.

(Embodiment 1) Next, (1) When registering a telephone number in a one-touch dial button (normal function),
(2) A case where the function of the telephone is further registered in the one-touch dial button (extended function) will be described in order.

(1) When Registering a Telephone Number in One-Touch Dial Button For example, a case in which a specific telephone number (dial number) is registered in one-touch dial button "OD1" will be described. As a procedure for registering the telephone number, as shown in FIG. 3, the push button of the “abbreviation / registration” button 2ed → the push button of the “#” button 2hc → the one-touch dial button “OD1” 2
da push button → dial number designation button (“1”-
Normally, a telephone number (dial number) having a maximum of 16 digits is input by pressing the "9", "0") buttons, and the "abbreviation / registration" button 2ed is pressed again. If an erroneous operation occurs during the series of registration procedures (S1 to S5), the RESET button 2zz is pressed at that time to temporarily cancel the series of registration procedures and then restart registration.

(2) A case where the function of the telephone is registered in the one-touch dial button A case in which, for example, a calling function of the handset 2 as one function of the telephone is registered in the one-touch dial button "OD2" will be described. Here, in order to call the slave unit 2,
Needless to say, it is necessary to press the “2” button 2eb after pressing the “extension” button 2bb.
As a procedure for further registering the function of the telephone, as shown in FIG.
Button 2ha push button → One-touch dial button "OD
2 "2db push button → dial number designation button" 2 "2e
The push button b → the “shortening / registration” button 2ed is pushed again. If an erroneous operation occurs during this series of registration procedures (S6 to S10), the RESET button 2zz is pressed at that point, so that the series of registration procedures is canceled once, and registration is restarted from the beginning.

As described above, in the case of registering a telephone number in the above-mentioned (1) one-touch dial button, after the first push button of the “abbreviation / registration” button 2ed, the “#” button 2
By pressing the button hc, the control unit 3 starts a process of registering a telephone number (a one-touch dialing telephone number data registration process). When registering the function of the telephone in the (2) one-touch dial button described above, after the first push button of the “abbreviation / registration” button 2ed, the “*” button 2
By pressing ha, the control unit 3 starts processing for registering the function of the telephone (processing for registering the extended function data of the one-touch dial).

When the telephone number is registered in the one-touch dial button, the control unit 3 sets the corresponding RAM
(Not shown) of the telephone number data 1
BC that can be identified as a telephone number registration in the byte
D data is stored. When the function of the telephone is registered in the one-touch dial button, the control unit 3
"*", "#", "A", "B", "C" for identifying the registration of the function of the telephone at the first digit of the function data stored in the corresponding RAM (not shown). ”,“ D ”
And the like (data other than BCD data) and a one- or two-digit number (for example, a function number “02” corresponding to the function of the “extension” button 2bb).

The control unit 3 reads out the telephone number or telephone function registered in each one-touch dial button in this manner by reading an R corresponding to each one-touch dial button.
The identification data of the head of the telephone number data stored in the memory area of the AM, the identification data of the head of the function data of the telephone, and the function data of the telephone according to the function-to-function number conversion table described above. The type can be determined, and registration processing can be performed in accordance with the type. Therefore, the one-touch dial buttons (“OD1” to “O
D5 ”) can reliably select the function of reading registered telephone numbers (one-touch dial processing) and the function of reading registered telephone functions (one-touch dial extended function processing).

The above will be described more specifically with reference to a flowchart (shown in FIG. 6) for explaining a procedure for registering a telephone number and a telephone function in a one-touch button. First, the control unit 3 sets a “short / register” button 2ed
It is determined whether the mode is the registration mode or the execution mode according to the presence or absence of the push button.

Registration mode (“Short / Registration” button 2ed
Is pressed), and if the "#" button 2hc is subsequently pressed, the control unit 3 determines that the mode is for registering a telephone number, and performs one-touch dialing telephone number data registration processing (S20). To S23). Also, in the registration mode, when the “*” button 2ha is subsequently pressed, the control section 3 determines that the mode is to register the function of the telephone, and performs the one-touch dial extended function data registration processing (S24, S24). S25). Further, in the registration mode, when neither the “#” button 2hc nor the “*” button 2ha is pressed, and another function button of the telephone is pressed, the control unit 3 sets the function assigned to the function button. A registration process for storing the number data in the memory area of the RAM corresponding to the one-touch dial button is executed (S26).

On the other hand, in the execution mode (when the "abbreviation / registration" button 2ed is not pressed), one-touch dial buttons (any of "OD1" to "OD5")
Is pressed, the control unit 3 reads the telephone number data and the function data of the telephone from the corresponding RAM. Then, the control unit 3 determines the identification data of the head of the read telephone number data and the identification data of the head of the function data of the telephone. Processing is performed. On the other hand, if it is determined that the registered data is the identification data of the function data of the registered telephone, the extended function processing of the one-touch dial is performed (the function number data of the telephone is read from the memory area of the RAM corresponding to the one-touch dial button, and By identifying the function data of the telephone according to the function-to-function number conversion table, the function data of the telephone can be read out (S20, S27 to S31). When the other function button of the telephone is pressed without being pressed, the reproduction process of the pressed function button itself is executed (S32).

(Embodiment 2) The operation sequence for registering a telephone function to a one-touch dial button in the present embodiment is compared with the operation sequence for registering a telephone in (Embodiment 1) described above. Can be performed in the order in which the buttons are actually operated. Of course, also in this embodiment, a telephone number can be registered to each one-touch dial button of (Embodiment 1), and the procedure in this case is the same as that of (Embodiment 1). A description will be omitted, and only the case where the function of the telephone is further registered in the one-touch dial button that can be performed in the order in which the user actually operates the buttons will be described.

(3) A case where a telephone function is further registered in the one-touch dial button A case will be described in which, for example, a call function of the slave unit 2, which is one function of the telephone, is further registered in the one-touch dial button "OD2". As a procedure for further registering the function of the telephone, as shown in FIG. 5, the push button of the “abbreviation / registration” button 2ed → the push button of the “extension” button 2bb → the push button of the dial number designation button “2” 2eb → the one-touch dial button "OD2" 2db push button → "Short / Register" button 2ed is pressed again. If an erroneous operation occurs during this series of registration procedures (S11 to S15),
At this time, by pressing the RESET button 2zz, a series of registration procedures are once canceled, and then registration is restarted from the beginning.

This registration procedure has a point that a function that cannot be operated with the function button of the telephone cannot be registered and the number of operation steps is limited (depending on the RAM capacity or the like). However, the function is intuitive and easy to understand. It has the advantage of easy operation.

The above-described registration procedure (shown in FIG. 5) is a flowchart (shown in FIG. 7) for explaining the procedure for further registering the telephone number and the function of the telephone in the one-touch button. And a "*" button 2ha (S2) in the flowchart (shown in FIG. 6) for explaining the procedure for registering the function of the telephone.
Since this is the same as the one using the “extension” button 2bb (S34) instead of 4), the description of the flowchart (shown in FIG. 7) is omitted.

As described above, the procedure for registering the extended function of the second embodiment is the same as the procedure for registering the extended function of the first embodiment in the order in which the user actually operates. There is an advantage that the ratio of erroneous operations at the time of registration can be further reduced.

[0034]

The multifunction telephone according to the present invention has a registration function in which a desired function different from the original function can be newly registered in addition to the original function of reading out a dial number on the input operation unit and making a call. Since a function button is provided and a control unit for registering a desired function to the registered function button is provided, for example, a function other than a dial number (for example, Registration by the user by operating the “call by machine” function and the “extension” button 2bb.
In addition, by combining function buttons that can assign only the functions required by the user to the function buttons on the telephone, the number of function buttons on the telephone can be further reduced while maintaining the required functions, There is an effect that the ratio of erroneous operations at the time of registration or read operation can be further reduced. In addition, one "one-touch dial"
A dial number and another function can be registered in the button at the same time, so that the one-touch dial function works when off-hook or on-hook dialing, and the other registered functions work when other non-calling is in progress.
