Abstract

PROBLEM TO BE SOLVED: To prevent a radio telephone set from malfunctioning against the intension of a user in the case of lighting up a back light. SOLUTION: When a key switch function limiting is set in the case that any of key switch groups of the telephone set is closed (YES in S101 and YES in S103), whether or not a backlight group provided in the key switch group has already been lighted is discriminated (S104). When the backlight group is not lighted (NO in S104), a function assigned to the key switch closed in the S101 is invalidated and the backlight group is lighted. On the other hand, when the backlight group has already been lighted (YES in S104), a usual operation is executed in the S106. As a result, when a user depresses a key at random in the dark to light up the backlight and the key happens to be a numeral entry key, even when the number differs from the initial number of a telephone number of an opposite party, the entered number is automatically invalidated.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention executes a function assigned to a turned on key switch every time one of the plurality of key switches is turned on, and executes all or one of the plurality of key switches. The present invention relates to a wireless telephone device for turning on a light provided in a unit.

[0002]

2. Description of the Related Art In recent years, wireless telephone devices such as portable telephones, PHSs and automobile telephones have become widespread for both young and old. In such a wireless telephone device, when a key switch is pressed, the backlight of the display and the backlight of all or some key switches are turned on for a predetermined time (for example, 10 seconds), so that even when the user is in the dark, 2. Description of the Related Art There has been known a device provided with a light-up function that allows characters, graphics, symbols, and the like (hereinafter, referred to as characters, etc.) displayed on a key switch to be visually recognized, and allows the operation result to be confirmed on a display. Then, when the user uses the wireless telephone device in the dark, the user presses an appropriate operation key by fumbling, turns on the backlight of the display and the backlight of all or some key switches, and then displays on the key switch. A desired operation key is pressed while visually recognizing a character or the like.

[0003]

However, in the above-described wireless telephone device, when the user presses an appropriate key switch by fumbling to light up in the dark, the function assigned to the key switch is also executed. Therefore, various problems may occur.

For example, if the key switch pressed for lighting up is a number input key and the number is different from the first number of the telephone number of the other party to be called, the clear key is pressed once. There is a problem that it is necessary to clear the numbers and the dial operation becomes complicated. In addition, the key switch pressed for lighting up is stored in the memory dial function (corresponding to the key switch with the other party's telephone number,
When the key switch is turned on, a function to automatically call the corresponding telephone number) is assigned,
There was a risk that a call would be received and the user would be charged unexpectedly.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and has as its object to provide a wireless telephone device in which a wireless telephone device does not perform an operation contrary to a user's intention when lighting up.

[0006]

In order to solve the above-mentioned problems, the present invention provides a function assigned to a turned on key switch every time one of a plurality of key switches is turned on. While performing, in a wireless telephone device that lights a light provided on all or a part of the plurality of key switches, key switch detection means for detecting an ON state of each of the plurality of key switches,
When the key switch detecting means detects that any one of the plurality of key switches is turned on, if the light is not turned on, the function assigned to the key switch is invalidated and the light is turned on. And a key switch function restricting means.

The wireless telephone device of the present invention (for example, a portable telephone,
PHS, car phone, etc.), when any one of a plurality of key switches is turned on, if the lights provided on all or some of the key switches are not turned on, the function assigned to the key switch is failed. And turn on the light. Then, characters and the like displayed on the key switch can be visually recognized even in the dark. Thereafter, when any key switch is subsequently turned on, the function assigned to the key switch is performed, and the light is continuously turned on. That is, when the user presses an appropriate key switch by fumbling to turn on the light in the dark, the light is turned on without executing the function assigned to the key switch. The processing of the key switch function restriction unit may be executed only when a key switch function restriction request is input by the user.

In the wireless telephone device of the present invention, for example, when the key switch appropriately pressed by the user to turn on the light in the dark is a number input key (a key to which a function of inputting a certain number is assigned), the number is changed. Even if the first digit of the telephone number of the other party to be called is different, the digit entry is automatically invalidated, and the user does not need to clear the digit entry. Even if a memory dial function is assigned to the key switch, the memory dial function is automatically disabled, so that no call is made against the user's will.

As described above, according to the wireless telephone device of the present invention, when the user wants to turn on the light, the function assigned to the key switch is not performed, so that the wireless telephone device operates in a manner contrary to the user's will. Never do. Also, for example, even if any key switch is turned on once in any time when the wireless telephone device is put in a bag, the function assigned to the key switch is not performed, so There is no hindrance.

[0010] The wireless telephone device of the present invention further comprises a light / dark judging means for judging the surrounding light / dark based on the light quantity. The key switch function restricting means comprises a key switch detecting means for detecting one of the plurality of key switches. When it is detected that the light is turned on, if the surroundings are determined to be dark by the light / dark judgment means, and if the light is not turned on, the function assigned to the key switch is invalidated and the light is turned on. It may be configured as follows.

In this case, when one of the plurality of key switches is turned on and the surroundings of the wireless telephone device are dark and the light is not lit, the function assigned to the key switch is defaulted and the light is lit. . This is because if the surroundings of the wireless telephone device are bright, the user can visually recognize the characters and the like displayed on the key switch even if the light is not turned on, so that there is no need to turn on the light. . Thus, it is possible to prevent the battery from being unnecessarily consumed by the lighting of the light.
When one of the key switches is subsequently turned on, the function assigned to the turned on key switch is performed, but the light is turned on only when the surroundings are determined to be dark by the brightness determining means. This is preferable in terms of prevention of battery consumption. The light / dark determining means compares the light amount obtained from the light detecting means such as an optical sensor with a predetermined value (a value which empirically determines the light amount at which a person starts to feel dark). For example, the surroundings may be determined to be dark.

In the wireless telephone apparatus according to the present invention, the key switch function restricting means is provided when the key switch detecting means detects that any one of the plurality of key switches is turned on. If the time belongs to a preset time zone and the light is not turned on, the function assigned to the key switch may be invalidated and the light may be turned on.

In this case, when any one of the plurality of key switches is turned on, if the time belongs to a preset time zone and the light is not turned on, the function assigned to the key switch is regarded as non-performance. Turn on the light. The reason for this is that if the time zone is set such that the user can visually recognize the characters and the like displayed on the key switch even if the light is not turned on by another lighting fixture or sunlight, for example, This is because there is no need to turn on. Thus, it is possible to prevent the battery from being unnecessarily consumed by the lighting of the light. In addition,
Subsequently, when any key switch is turned on, the function assigned to the turned on key switch is performed, but the light is turned on only when the turned-on time belongs to the set time zone. Is preferable in terms of prevention of battery consumption. In addition, the time zone may be arbitrarily set by the user, for example, or may be set from the sunset time in winter to the sunrise time, or the sunset time in each season may be set. The time zone from the time until the sunrise time is stored in a memory such as a ROM, and the time zone according to the season is read from the time zone stored in the memory using the clock function of the wireless telephone device and set. Is also good.

In the wireless telephone apparatus according to the present invention, the key switch detecting means detects that any one of the plurality of key switches has been turned on before the predetermined time elapses. A light-on control means may be provided for turning off the light when it is not detected that any of them is turned on.
In this case, the light is automatically turned off when a predetermined time has elapsed since the last time the key switch was turned on, so that the battery can be prevented from being unnecessarily consumed.

When this process is started, first, in step (hereinafter referred to as S) 101, it is determined whether any key switch of the key switch group 12 has been turned on. If any key switch is turned on (YES in S101), the process proceeds to S103, and it is determined whether the key switch function restriction is set. The key switch function restriction is a function for defaulting the function assigned to the turned on key switch when the user turns on the key switch to light the backlight group 13 (that is, to light up). The user can arbitrarily select and set by using the select key 12c. Whether the key switch function restriction is set or not is determined, for example, by the on / off state of the function restriction setting flag (the function restriction setting flag is turned on when the key switch function restriction is selectively set by the select key 12c, and this setting is made). It turns off when it is released).

If the key switch function restriction has been set in S103 (YES in S103), the process proceeds to S10.

(NO in 101), the process proceeds to S107, and it is determined whether a predetermined time (for example, 10 seconds) has elapsed since the last key switch was turned on, and if the predetermined time has not elapsed (S101).
If the predetermined time has elapsed (YES in S101), it is determined that the user does not intend to turn on the key switch continuously, and the process proceeds to S108, where the backlight is used to prevent the battery 18 from being consumed. The group 13 is turned off, and the process returns to S101.

Next, a description will be given of an operation of the radio telephone device 10 of the present embodiment in a case where, for example, the user selects and sets the key switch function restriction using the select key 12c, and then makes a call in the dark. Before starting this operation, the backlight group 13 of the wireless telephone device 10 is turned off, so that the user cannot visually recognize characters and the like displayed on the touch surface of the key switch group 12. For this reason, the user gropingly presses any key switch of the key switch group 12 appropriately. Then, in the flowchart of FIG. 2, a key operation is performed (YES in S101), a function restriction setting is performed (YES in S103), and the light is turned off (S104).
Is NO), the process proceeds to S105, and the function assigned to the key switch appropriately pressed by groping is invalidated, and only the backlight group 13 is turned on. Thus, even if the key switch appropriately pressed by groping is, for example, the numeric input key 12d, the function of inputting the numeric assigned to the numeric input key 12d is invalidated.
Since 3 is turned on, the user can visually recognize the characters and the like displayed on the touch surface of the key switch group 12, and also can visually recognize the content displayed on the display unit 11.

Thereafter, the user operates the key switch group 12 to input the telephone number of the other party while visually confirming these illuminated characters and the like, and turns on the call start key 12a. During this operation, every time each key switch is turned on, there is a key operation in the flowchart of FIG. 2 (S1).

In S106, the function assigned to the key switch that has been turned on is executed, and the backlight group 13 is kept turned on. This will call the other party ’s phone number,
When connected to the communication line, it is possible to talk with the other party via the speaker 14 and the microphone 15.

As described in detail above, according to the wireless telephone device 10 of the present embodiment, for example, the key switch appropriately pressed by the user to light up in the dark is the number input key 1
2d (key to which a function to input a certain number is assigned)
In the case of, even if the number is different from the first number of the telephone number of the person who is going to make a call, the number entry is automatically disabled, so that the user clears the number entry No need. Even if a memory dial function is assigned to the key switch, the memory dial function is automatically disabled, so that no call is made against the user's will.
Thus, an effect is obtained that the radio telephone device 10 does not perform an operation contrary to the user's intention when the user lights up.

If, for example, any key switch of any key switch group 12 is turned on at any time when the wireless telephone device 10 is put in a bag, the light is lit up. After a lapse of a predetermined time, the light is turned off and the function assigned to the key switch is invalidated, so that no particular problem occurs.

The controller 17 of the present embodiment corresponds to the key switch detecting means and the key switch function limiting means of the present invention, and corresponds to S101 in the flowchart of FIG.
Corresponds to the processing of the key switch detecting means.
4. The processing of S105 corresponds to a key switch function restriction unit.

[Second Embodiment] FIG. 4 is a schematic block diagram showing a circuit configuration of the present embodiment. The wireless telephone device 20 of the present embodiment includes an optical sensor 21 on the surface on which the key switch group 12 is provided, and the controller 17
Since the configuration is the same as that of the wireless telephone device 10 of the first embodiment except that it is connected so as to input the detection signal of the first embodiment, the same reference numerals are given to the same components, and the description thereof will be omitted.

Next, the operation of the wireless telephone device 20 of the present embodiment will be described. When the power switch 12e is turned on, the controller 17 of the wireless telephone device 20 starts the processing shown in the flowchart of FIG. S in this process
201 and S203 to S208 are respectively S101 and S103 to S1 in the flowchart of FIG. 2 of the first embodiment.
The processing is the same as that of the first embodiment except that it is determined in S201 that there is a key operation (YES in S201) and then in S202 whether or not the surroundings of the wireless telephone device 20 is dark. That is, in S202, the controller 17 compares the amount of light detected from the optical sensor 21 with a predetermined value (a value that empirically determines the amount of light at which humans start to feel dark). (YES in S202), the process proceeds to S203 and below. On the other hand, if the light amount exceeds a predetermined value, the surroundings are determined to be bright (NO in S202), and the process proceeds to S209 without turning on the backlight group 13. , Execute the function assigned to the key switch turned on in S201. Note that the controller 17 of the present embodiment corresponds to the light / dark judgment means of the present invention, and the processing of S202 corresponds to the processing of the light / dark judgment means.

According to the wireless telephone device 20 of the present embodiment,
In addition to the same effects as those of the first embodiment, the user can turn on the light if the surroundings of the wireless telephone device 20 are bright regardless of whether the key switch function restriction at the time of light-up is selectively set by the user. Even if it is not turned on, the characters and the like displayed on each key switch of the key switch group 12 can be visually recognized, so that the backlight group 13 is not turned on. Therefore, it is possible to prevent the battery from being consumed unnecessarily due to the lighting of the light.

The embodiments of the present invention are not limited to the above-mentioned embodiments at all, and it goes without saying that various forms can be adopted as long as they fall within the technical scope of the present invention. For example, in the above embodiment, the backlight group 13 is configured to illuminate all the key switches of the key switch group 12 from the back side, but only a part of the key switches of the key switch group 12 (for example, the numeric input key 12d). May be illuminated.

Further, in the above embodiment, the user is allowed to select and set the key switch function restriction.
The key switch function may be limited while the power switch 12e is on. For example, in the flowchart of FIG. 2, there is a key operation (YE in S101).
After the determination of S), the process may proceed to S104 immediately.

Further, in the first embodiment, the controller 17 enables the user to set a time period during which the key switch function restriction is executed (a time period in which the surroundings of the wireless telephone device 10 becomes dark). When turned on, the process of the flowchart in FIG. 6 may be executed. That is, in S101, there is a key operation (YE in S101).
After S), it is determined in S102 whether or not the time at which the key operation was performed is within the set time zone. If the time is within the set time zone (YES in S102), the surroundings are determined to be dark,
The processing after S103 described above is executed. On the other hand, if it is out of the set time (NO in S102), it is determined that the surroundings are bright,
Proceeding to S109, execute the function assigned to the key switch turned on in S101 without turning on the backlight group 13, and return to S101. In this case, if the time when the key is operated is outside the set time zone, the user can visually recognize the characters and the like displayed on each key switch of the key switch group 12 even if the light is not turned on. Does not light up. Therefore, it is possible to prevent the battery from being consumed unnecessarily due to the lighting of the light.

As the set time zone in S102 of FIG. 6, the time from the sunset time in winter to the sunrise time may be stored in a memory such as the ROM of the controller 17 in advance. Since the sunset time is the earliest and the sunrise time is the latest in the winter season (especially the winter solstice) throughout the year, setting this time zone throughout the year makes the sun fall and the surroundings of the wireless telephone device 10 become dark. There is no possibility that the light will not be lit up. Alternatively, the time zone from the sunset time to the sunrise time for each season is stored in a memory such as the ROM of the controller 17, and the time zone stored in the memory is used by using the clock function of the wireless telephone device 10. May be read out and set. As described above, if the determination as to whether or not to perform light-up is made more strictly according to the season, useless consumption of the battery 18 can be more effectively prevented.
