Description

1 A 2346006t TELEPHONE

BACKGROUND OF THE INVENTIO

The present invention relates to a telephone such as a f ixed telephone, a portable telephone..' and a PHS, and a method of limiting call-incoming operation of the telephone, and more particularly to a telephone which is able to automatically ef f ect a changeover call- incoming operation corresponding to a time zone.

With conventional telephones, a user is able to select the tone volume of a ringer during call incoming and a singing melody, but the selected state is fixed unless the user changes. it, and even in a ni ght time zone from evening till morning when the surroundings become quiet and even in a daytime zone when the surroundings are noisy, call incoming is signaled with the same call- incoming tone volume or call-incoming pattern.

For this reason, in the case 'of a telephone in which the call-incoming tone volume is set to a high level or the call-incoming pattern is set to a quick one which sounds bustling, during the night, the high level of the call-incoming tone volume, the high tone of the call-incoming pattern, and the bustling quality of the call- incoming pattern impart discomfort and annoyance to the surrounding people. In a case where the call-incoming tone volume is set to a low level or the call- incoming pattern is set to a slow call-incoming pattern, 2 the call-incoming tone during the daytime when the surroundings are noisy becomes difficult to hear.

To overcome such a problem, Japanese Utility Model Laid-open 546154/(1993) discloses a telephone with a call-incoming-operation limiting function which is arranged such that, during a specific time zone- in a day, the output to the ringer during call incoming is cut off, and call incoming is signaled by a call- incoming lamp alone.

However, with such a conventional telephone with a callincoming-operation limiting function, there is a problem in that the user is unable to know call incoming if the user is not looking at the lamp. I In addition, there are also cases where the user is unaware of the fact that there has been a changeover in the signaling method, and an inconvenience occurs as a result.

In addition, there are cases where the answering phone function or the like is used every day during a f ixed time zo ne, but in such cases it is very troublesome to set the answering phone function on each such occasion every day and to cancel it when it has become unnecessary. Furthermore, the user may often forget to set or cancel the answering phone function or the like.

0 TRAMaRY F THE INVENTIO The present invention overcomes the abovedescribed conventional problems, and its object is to provide a telephone with a cal 1- incoming-operat ion limiting function which limits 3 the call-incoming operation in correspondence with a time zone by a method whereby the user is capable of noticing call incoming, and to provide a method of limiting call-incoming operation which is capable of overcoming the trouble with whic h the setting for limitation must be performed every day, and of overcoming the problem of forgetting to perform the setting or cancellation.

Accordingly, the telephone with a call-incomingoperation limiting function in the present invention is provided with: ringer- tone-vo lume controlling means for controlling a tone volume of a ringer during call incoming; and call-incoming-operation limiting function controlling means for instructing the ringer- tone-vo lume controlling means at the time set by a user to change over the tone volume to a tone volume set by the user.

In addition, the telephone with a call-incomingoperation limiting function in the present invention is provided with: cal 1- incoming-pat tern controlling means for controlling a ringing pattern of a ringer during call incoming; and call-incoming-operation limiting function controlling means for instructing the call-incoming-pattern controlling means at the time set by a user to change over the ringing pattern to a ringing pattern set by the user.

In addition, the telephone with a call-incoming- operation limiting function in the present invention is provided with: vibrator controlling means for controlling a 4 vibrator for signaling call incoming; and call-incomingoperation limiting function controlling means for instructing the vibrator controlling means at the time set by a user to effect a changeover to signaling of call incoming by the 5 vibrator.

Furthermore, the telephone with a call-incomingoperation limiting function in the present invention is provided with: answering-phone- function controlling means for controlling an answering phone function; and callincoming-operation limiting function controlling means for instructing the answering-phone-f unction controlling means at the time set by a user to use the answering phone function during call incoming.

Furthermore, in the method of limiting call-incoming operation of a telephone, the tone volume of a ringer during call incoming is automatically changed over to a set tone volume each time a time zone set by a user periodically arrives. Alternatively, the ringing pattern of a ringer during call incoming is automatically changed over to a set ringing pattern each time a time zone set by a user periodically arrives, or the signaling method during call incoming is automatically changed over to a method of signaling by vibration each time a time zone set by a user periodically arrives. Still alternatively, the response during call incoming is automatically changed over to a response by an answering phone function each time a time zone set by a user periodically arrives.

For this reason, by setting a time zone when the surroundings become quiet and by limiting the call-incoming operation during that time zone, the user is capable of knowing call incoming without imparting discomfort and annoyance to the surrounding people. In addition, 'once the setting for limiting the call- incoming operation is performed, it is unnecessary to provide the setting or cancel it every day and it become possible to overcome the problem of forgetting to perform the setting or cancellation.

According to the first aspect of the present invention, there is provided a telephone with a call-incoming-operation limiting function which has clock means for measuring the time and changes over call-incoming operation according to the time, comprising: ringer-tone-volume controlling means for controlling a tone volume of a ringer during call incoming; and call-incoming-operation limiting function controlling means for instructing the ringer-tone- volume controlling means at the time set by a user to change over the tone volume to a tone volume set by the user.

DETATLED DE5CRIPTTON OF THE PREFERRED PMRQnTMENIS Hereafter, a description will be given of the embodiments of the present invention with reference to the drawings.

First Embodiment A telephone with a call-incoming-operation limiting function in accordance with a first embodiment is able to automatically reduce the volume of the call-incoming tone during a set time zone.

As shown in Fig. 1, this telephone is provided with a communication control unit 1 for controlling call origination 14 and termination as well as a call, a clock unit 2 for holding the present time, a ringer 5 for generating the ringing tone, a ringer-tone- volume control unit 4 for controlling the tone.volume of the ringer 5, and a call-incoming-operation limiting-function control unit 3 for instructing the ringer-tone-volume control unit 4 to change the tone volume of the ringer during a time zone set by a user.

This call-incoming-operation limiting-function control unit 3 holds ringer-tone-volume change information which describes the relationship between the time zone set by the user and the tone volume of the ringer during that time zone. The call- incoming-operation limiting- function control unit 3 instructs the ringer- tone-vo lume control unit.4 to change the tone volume of the ringer to a set tone volume if the time of the clock unit 2 has coincided with the time zone described in the ringer-tone-volume change information.

Fig. 2 is a diagram explaining the operation of this telephone with a call-incoming-operation limiting function. Here, a description will be given of a case where, every day, the call-incoming tone volume of the telephone during the usual time is set to a tone volume a, while the call-incoming tone volume during a call -incoming-operat ion limited time zone Tl to T2 is set to a tone volume b.

First, by using an operating portion of the telephone with a call-incoming-operation limiting function, the user sets the starting time Tl and the ending time T2 of the call-incoming-operation limited time zone as well as the tone volume b of the ringer 5 during that call-incoming-operation limited time zone. The thus-set starting time Tl and the ending time T2 of the call-incoming- operation limited time zone and the tone volume b are held in the call-incoming-operation limitingfunction control unit 3 as the ringer-tone-volume change information.

When the time of the clock unit 2 has coincided with the starting time Tl of the call-incoming-operation limited time zone, the call-incoming-operation limiting-function control unit 3 holding the ringer-tone-volume change information instructs the ringer- tone-volume control unit 4 to change the tone volume of the ringer to the tone volume b on the basis of the ringer- tone-volume change information. In response, the ringer-tone-volume control unit 4 causes the ringer 5 to ring with the tone volume b when the operation during call incoming is instructed from the communication control unit In addition, when the time of the clock unit 2 has coincided with the ending time T2 of the.call-incomingoperation limited time zone, the call-incoming-operation limiting-function control unit 3 instructs the ringertone-volume control unit 4 to stop the change to the tone volume b on the basis of the ringertone-volume change information.

In response, the ringer-tone-volume control unit 4 causes the ringer 5 to ring with its former tone volume a when the operation 16 during call incoming is instructed from the communication control unit 1.

Thus, in this telephone, after a time zone is designated, the tone volume of the ringer during that time zone can be limited. Accordingly, by setting the tone volume of the ringer to a lower level during, for example,, thb time zone in and after the evening when the surroundings become quiet, the user is able to know call incoming by the call-incoming tone of a volume which does not annoy people in the surroundings even if there is call incoming during that time zone.

It should be noted that signaling of call incoming by means of a lightemitting means may also be effected.

Further, the time zone during which the tone volume of the ringer is limited may be set not only in periods of 24 hours or one day but also in periods of one week or one month, or may be set only once, e.g., year XX, month YY, and day ZZ, AA hour a.m..

Second Embodiment A telephone with a call-incoming-operation limiting function in accordance with a second embodiment is able to change a callincoming pattern by designating a time zone.

As shown in Fig. 3, this telephone is provided with the communication control unit 1, the clock unit 2, the call-incoming-operation limitingfunction control unit 3, and 25 the ringer 5, as well as a ringer call-incoming pattern control unit 6 for controlling the ringing pattern (call-incoming pattern) of the ringer 5.

The call-incoming-operation limiting- function control unit 3 of this telephone holds call-incoming pattern change information which des cribes th e relationship between the time zone set by the user and the call-incoming pattern during that time zone. The call- incoming-operation limiting-function control unit 3 instructs the ringer call-incoming pattern control unit 6 to change the callincoming pattern of the ringer 5 if the time of the clock unit 2 has coincided with the time zone described in the callincoming pattern change information.

Fig. 4 is a diagram explaining the operation -of this telephone with a call-incoming-operation limiting function. Here, a description will be given of a case where, every day, the ringer 5 is caused to ring with a call-incoming pattern c as the call-incoming pattern of the telephone during the usual time, while the ringer 5 is caused to ring with a call-incoming pattern d during the call- incoming-operat ion limited time zone TI to T2.

First, by using the operating portion of this telephone, the user sets the starting time T1 and the ending time T2 of the cal 1- incoming-operat ion limited time zone as well as the call-incoming pattern d of the ringer 5 during that call incoming-operation limited time zone. The thus-set starting time T1 and the ending time T2 of the call-incoming-operation limited time zone and the call-incoming pattern d are held in 18 the call-incoming-operation limiting- function control unit 3 as the, call-incoming pattern change information.

When the time of the clock unit 2 has coincided with the starting time Tl of the call-incoming-operation limited time zone, the call-incoming-operation limiting-function control unit 3 holding the cal.1-incoming pattern change information instructs the ringer call-incoming pattern control unit 6 to change the call-incoming pattern to the call-incoming pattern d on the basis of the call-incoming pattern change information. In response, the ringer call-incoming pattern control unit 6 causes the ringer 5 to ring with the call-incoming pattern d when the operation during call incoming is instructed from the communication control unit 1.

In addition, when the time of the clock unit 2 has coincided with the ending time T2 of the call-incomingoperation limited time zone, the call-incoming-operation limiting-function control unit 3 instructs the ringer call-incoming pattern control unit 6 to stop the change to the call-incoming pattern d on the basis of the call-incoming pattern change information. In response, the ringer call- incoming pattern control unit 6 causes the ringer 5 to ring with its former call-incoming pattern c when the operation during call incoming is instructed from the communication control unit 1.

As for the call-incoming pattern, it is possible to set various call-incoming patterns by changing the tone, the 19 tone interval, the melody, and the like. As the call-incoming pattern during the call-incoming-operation limited time zone, it is possible to reduce discomfort imparted to the surrounding people.

Thus, in this telephone, after a time zone is designated, the call-incoming pattern during thattime zone can be designated. Accordingly, by setting the call-incoming pattern to a quiet one during, for example, the time zone in and after the evening when the surroundings become quiet, the user is able to know call incoming by the call-incoming tone with a quiet call- incoming pattern without annoying people in the surroundings even if there is call incoming during that time zone.

It should be noted that, in this telephone as well, signaling of call incoming by means of the light-emitting means may also be effected in conjunction with the change of the call-incoming pattern. Further, the time zone for which the change of the call-incoming pattern is designated may be set not only in periods of one day but also in periods of one week or one month, or may be set only once by designating the date and the time. Third Embodiment A telephone with a call-incoming-operation limiting function in accordance with a third embodiment is able to ef f ect a changeover to signaling of call incoming by means of vibration.

As shown in Fig. 5, this telephone is provided with the communication control unit 1, the clock unit 2, and the call-incoming-operation limiting- function control unit 3, as well as a call-incoming vibrator 8 for signaling call incoming 5 by means of vibration and a call-incomingvibrator control unit 7 for operating the call-incoming vibtator 8 during call incoming.

The call-incoming-operation limiting-function control unit 3 of this telephone holds call- incoming-vibrator operation change information which describes the time zone which is set by the user and during which signaling of call incoming is effected by the vibrator. The call-incomingoperation limiting-function control unit 3 instructs the call-incoming-vibrator control unit 7 to control the call- incoming vibrator 8 during call incoming if the time of the clock unit 2 has coincided with the time zone described in the call-incoming-vibrator operation change information.

Fig. 6 is a diagram explaining the operation of this telephone with acall-incoming-operation limiting function.

Here, a description will be given of a case where, every day, call incoming is signaled by causing the ringer to ring during the usual time, while call incoming is signaled by using the vibrator during the callincoming-operation limited time zone Tl to T2.

First, by using the operating portion of this telephone, the user sets the starting time T1 and the ending time T2 of 21 the call-incoming-operation limited time zone, and sets the call- incoming vibrator 8 as a call-incoming signaling means during that call- incoming-operation limited time zone. The thus-set starting time Tl and the ending time T2 of the call-incoming-operation limited time zone and the callincoming vibrator 6 as the signaling means are held in the call-incoming-operation limitingfunction control unit 3 as the call-incoming-vibrator operation change information.

When the time of the clock unit 2 has coincided with the time Tl, the call-incoming-operation limiting-f unction control unit'3 holding the call-incoming-vibrator operation change information instructs the call-incoming-vibrator control unit 7 to control the call- incoming vibrator 8 on the basis of the call-incoming-vibrator operation change information. In response, the call-incoming-vibrator control unit 7 causes the call-incoming vibrator 8 to vibrate to ef f ect signaling when the operation during call incoming is instructed from the communication control unit 1.

In addition, when the time of the clock unit 2 has coincided with the time T2, the call-incoming-operation limiting-function control unit 3 instructs the callincoming-vibrator control unit 7 to stop controlling the call-incoming vibrator 8 on the basis of the callincoming- vibrator operation change information. Whenthereis call incoming afterwards, usual signaling by the ringer is performed.

The call-incoming-operation limiting-function control unit 3 of this telephone holds answering-phonefunction operation change information which describes the time zone which is set by the user and during which a changeover to the answering phone function is ef]Eected. The callincoming-operation limiting- function control unit 3 instructs the answe.ring-phone-function cont rol unit 9 to use the answering phone function 10 during call incoming if the time of the clock unit 2 has coincided with the time zone described in the answering-phone- function operation change information.

Fig. 8 is a diagram explaining the operation of this telephone with a call-incoming-operation limiting function. Here, a descriptio n will be given of a case where, every day, a usual call-incoming response is made during the usual time, while a call-incoming response is made by means of the answering phone function during the call-incoming-operation limited time zone Tl to T2.

First, by using the operating portion of this telephone, the user sets the starting time TI and the ending time T2 of the call- incoming-operation limited time zone, and sets the answering phone function 10 as a responding means during that call-incoming-operation limited time zone. The thus-set starting time TI and the ending time T2 of the callincoming-operation limited time zone and the answering phone function 10 as the responding means are held in the call- 24 incoming-operation limiting-function control unit 3 as the answering- phone-function operation change information.

When the time of the clock unit 2 has coincided with the starting time Tl of the call-incoming-operation limited time zone, the call-incoming-operation limiting-function control unit 3 holding the answering-phone- function operation change information instructs the answering-phone-function control unit.9 to control the answering phone function 10 during call incoming on the basis of the answering-phone-function operation change information. In response, the answeringphone-function control unit 9 causes the answering phone function 10 to operate when the operation during call incoming is instructed from the communication control unit 1.

In addition, when the time of the clock unit 2 has coincided with the ending time T2 of the call-incomingoperation limited time zone, the call-incoming-operation limiting-function control unit 3 instructs the answeringphone-function control unit 9 to stop controlling the answering phone function 10 on the basis of the answer ing-phone- function operation change information. When there is call incoming afterwards, the usual call-incoming response is made.

Thus, in this telephone, after a time zone is designated, a changeover to the answering phone function can be effected. once the user ef f ects the setting of changing over the response in the night to the answering phone function, the changeover to the answering phone during the designated time zone can be effected automatically.

Further, that time zone may be set not only in periods of one day but also in periods of one week or one month, or may be set only once by designating the date and the time.

Fifth Embodiment A telephone with a call-incoming-operation limiting function in accordance with a f if th embodiment has a combination of the functions of the first, second, third, and fourth embodiments.

As shown in Fig. 9, this telephone is provided with the communication control unit 1 for controlling call origination and termination as well as a call; the clock unit 2 for holding the present time; the ringer 5 for generating the ringing tone; the ringer-tone- volume control unit 4 for controlling the tone volume of the ringer 5; the ringer call-incoming pattern control unit 6 for controlling the call-incoming pattern of the ringer 5; the call-incoming vibrator 8 for signaling call incoming by means of vibration; the call-incoming-vibrator control unit 7 for operating the call-incoming vibrator 8 during call incoming; the answering phone function 10 for responding to call incoming and recording a received message; the answering-phone-f unction control unit 9 for controlling the answering phone function 10 during call incoming; and the call-incomingoperation limiting-function control unit 3 for changing the call-incoming operation during the time zone set by the user to the one set by the user.

26 Fig. 10 is a diagram explaining the operation of this telephone with a call -incoming-operation limiting function. Here, a description will be given of a case where, every day, usual signaling of call incoming by means of the ringer 5 is ef f ected during a time zone TO to Tl, signaling of call incoming by means of the call-incoming vibrator 8 is effected during a time zone Tl to T2, and a call-incoming response is made by using the answering phone function 'is effected during a time zone T2 to T3.

First, by using the operating portion of this telephone, the user sets the starting time Tl and the ending time T2 of the call- incoming-operation limited time zone Tl to T2, sets the starting time T2 and the ending time T3 of the callincoming-operation limited time zone T2 to T3, sets the call-incoming vibrator 8 as the call-incoming signaling means for the set call-incoming-operation limited time zone Ti to T2, and sets the answering phone function as the call-incoming responding means for the set cal 1incoming-operat ion limited time zone T2 to T3. The relationship between, on one hand, the thus-set starting time Tl and the ending time T2 of the call-incoming-operation limited time zone and, on the other hand, the call-incoming vibrator, as well as the relationship between, on one hand, the starting time T2 and the ending time T3 of the ca 11 - incoming-ope ration limited time zone and, on the other hand, the answering phone function, are held in the call- incoming-operation limiting-function control unit 3 as 27 the call-incoming-vibrator operation change information and the answering-phone-function operation change information.

When the time of the clock unit 2 has coincided with the starting time Tl of the call-incoming-operation limited time zone Tl to T2, the call-incoming-operation limitingfunction control unit 3 holding the c&ll-incoming-vibrator operation change information and the answering-phone-f unction operation change information instructs the call-incomingvibrator control unit 7 to control the call-incoming vibrator 8 during call incoming on the basis of the call-.incomingvibrator operation change information. In response, the call-incoming-vibrator control unit 7 causes the call-incoming vibrator 8 to vibrate to effect signaling when the operation during call incoming is instructed from the communication control unit 1.

In addition, when the time of the clock unit 2 has coincided with the time T2, the call-incoming-operation limiting-function control unit 3 instructs the callincoming- vibrator control unit 7 to stop controlling the call-incoming vibrator 8 on the basis of the callincoming-vibrator operation change information, and also instructs the answering-phonefunction control unit 9 to control the answering phone function 10 during call incoming on the basis of the answering-phone- function operation change information. In response, the answering-phone- function control unit 9 causes the answering phone function 10 to operate 28 when the operation during call incoming is instructed from the communication control unit 1.

In addition, when the time of the clock unit 2 has coincided with the ending time T3 of the call-incoming- operation limited time zone, the call-incoming-operation limiting- function control unit 3 instkucts the answeringphone-function control unit 9 to stop controlling the answering phone function 10 on the basis of the answering-phone- function operation change information. When there is call incoming afterwards, the usual call-incoming response is made.

Thus, in this telephone,. after a time zone is designated, the callincoming signaling means can be changed over to the vibrator, a changeover to the answering phone can be effected, and the tone volume or the ringing pattern of the ringer can _15 be changed over.

Further, that time zone may be set not only in periods of one day but also in periods of one week or one month. Sixth Embodiment A telephone with a call-incoming-operation limiting function in accordance with a sixth embodiment is able to inf orm the user of the fact that the operation has proceeded to the call-incoming- operation limited time zone.

As shown in Fig. 11, this telephone is provided with a call-incomingoperation-limited time signaling unit 11 for signaling the user that the time has arrived for changing the call- incoming operation. The other arrangements are the same 29 as those of the fifth embodiment (Fig. 9).

In this telephone, as described in the f if th embodiment, when the limitation of the call-incoming operation shown in Fig. 12 is effected, if, by using the operating portion, the user sets the starting time T1 and the ending time T2 of the call- incoming-operation limited time Z'one T1 to T2, sets the starting time T2 and the ending time T3 of the callincoming-operation limited time zone T2 to T3, sets the call-incoming vibrator 8 as the call-incoming signaling means for that call-incoming-operation limited time zone T1 to T2, and sets the answering phone function as the call-incoming responding means for the call-incoming-operation limited time zone T2 to T3, then the relationship between, on one hand, the thus-set starting time Tl and the ending time T2 of the call-incoming-operation limited time zone and, on the other hand, the call-incoming vibrator, as well as the relationship between, on one hand, the starting time T2 and the ending time T3 of the call-incomingoperation limited time zone and, on the other hand, the answering phone function, are held in the call-incoming-operation limiting-function control unit 3 as the call- incoming-vibrator operation change information and the answering-phone- function operation change information.

At this time, information on the starting time T1 and the ending time T2 of the cal 1- incoming-operat ion limited time zone T1 to T2, as well as the starting time T2 and the ending time T3 of the call-incoming-operation limited time zone T2 to T3, is concurrently stored in the call-incomingoperation-limited time signaling unit 11.

At the starting time Tl of the cal 1- incoming-operat ion limited time zone T1 to T2, the call-incoming-operation limiting-function control unit 3 holding the callincoming-vibrator operation change information and the answering-phone-function operation change information instructs the call-incoming-vibrator control unit 7 to control the call-incoming vibrator 8 during call incoming, as described in the fifth embodiment and, at the time T2, also instructs the answering- phone-function control unit 9 to control the answering phone function 10 during call incoming.

Meanwhile, when the time of the clock unit 2 has coincided with the time Tl, T2, and T3, the call-incoming- operation-limited time signaling unit 11 notifies the call-incoming- operation limiting-function' control unit 3 to that effect. The call - incoming- operation limiting-f unction control unit 3, after being notified, instructs the ringer- tone-vol ume control unit 4 or the ringer call-incoming pattern control unit 6, and causes the ringer 5 to operate.

Thus, with this telephone, since the ringer rings when the call-incoming operation mode is changed over, the user is able to recognize that there has been a change in the call-incoming operation mode.

It should be noted that the changeover of the call-incoming operation mode can be signaled not only by 31 operating the ringer but by using the call-incoming vibrator or the. light-emitting means.

Seventh Embodiment A telephone with a call-incoming-operation limiting function in accordance with a seventh embodiment automatically sets a call-incoming-operation limited'time zone by referring to the time zones set in the past.

As shown in Fig. 13, this telephone is provided with a unit 12 for setting call-incoming operation change information. This unit 12 for setting call-incoming operation change information holds records of the set time of changing the call-incoming operation, which have hitherto been changed by the user, and sets the time of changing the call-incoming operation by averaging the held time when the change has been effected a predetermined number of times. The other arrangements are the same as those of the sixth embodiment (Fig.

The unit 12 for setting call-incoming operation change information of this telephone sets the time of changing the call-incoming operation in the procedure shown in Fig. 15.

Step 1: When a mode for setting the time of changing the call-incoming operation is designated, Step 2: a counter I is initialized.

Step 3: When the user effects the operation of changing the call-incoming operation, the pattern of that operation change (e.g., a pattern of change from the mode of 32 signaling call incoming by the ringer to a mode of signaling call incoming by the call-incoming vibrator) is detected, and Step 5: a comp arison is made between the counter value of that pattern and a predetermined number of times (a predetermined number of times N of mode change for determining the time setting) If the number of changes is less than or equal to the predetermined number of times N, Step 4: the counter value of that pattern is incremented by 1, and the set time of change is recorded.

Step 5: When the mode changing operation is performed, and if the counter value has reached the predetermined number of times N when a comparison is made between the counter value of that pattern and the predetermined number of times N, Step 6: t he average time of the N number of the time of change is calculated, Step 7: the calculated average time is set as the mode changing time of that pattern, and Step 8: mode-change setting processing ends.

It should be noted that the patterns of mode change can be detected from combinations of all the call-incoming signaling means set for the time zone during which the call-incoming operation is limited.

In addition, as for the method of calculating the average time, apart from determining the average time as an arithmetical mean, a central value in the distribution of the detected time may be set as the time to be determined. Still alternatively, a determined time zone may be divided into certain time periods to obtain a frequency distribution, and its mode may be set as the time to be determined.

In addition, as shown in Fig. 14, an arrangement may be provided such that a time period Et is defined in advance, and the detected mode changes (Tl, T2, an d T4) which fall within that time period are made subject to averaging processing, while the mode change M) which falls outside that time period is discarded.

Thus, with this telephone, the time for limiting the call-incoming operation can be automatically set by referring to the time set in the past.

As is apparent from the foregoing description, the telephone with a call incoming-operat ion limiting function in accordance with the present invention is capable of automatically limiting the call-incoming operation during a set time zone and of signaling call incoming without imparting discomfort and annoyance to the surrounding people.

In addition, it is possible to dispense with the trouble of providing the setting for limiting the call-incoming operation every day, and it is possible to prevent forgetting to perform the setting or canceling thereof.

Further, with the telephone with a call-incomingoperation limiting function which is provided with the signaling means for signaling the arrival of the time set by the user, the point of time in changing over the call-incoming 34 operation mode can be signaled to the user.

Further, with the telephone with a call-incomingoperation limiting function which is provided with the call-incoming-operation change information setting means, even if the user does not set the time zone, the time zone for limiting the call- incoming operation can be set automatically by referring to the time zones set in the past.

In addition, in accordance with the method of limiting call-incoming operation of a telephone, the user can be notif ied of call incoming without imparting discomfort and annoyance to the surrounding people, an d it is possible to dispense with the trouble of providing a setting every day and prevent forgetting to perform the setting or cancellation.

In addition, in accordance with the method in which the call-incoming response during the time zone set by the user is ef f ected by the answering phone function, the response during a time zone when the surroundings become quiet or during a time zone when a person is absent can be automatically effected by the answering phone function.
