In recent years, the penetration rate of portable terminals has been remarkable, and the era of each and every one is near. A variety of problems have arisen accordingly. For example, recently, accidents when using a mobile phone while driving a car have increased.
In other words, if there is an incoming call while driving, it is very dangerous because the user searches for the incoming call button of the mobile phone while driving.

Conventionally, there has been no function of automatically adjusting the ringer level of incoming calls. As for the usage of the portable terminal, it is put in a bag or in a pocket on the chest. Many people set the ringer level to the maximum in the city or at the station because of the loud noise and the inability to hear the ringtone. In this case, the caller notices that the ringer sound is ringing and tries to answer the call, but when the user removes the mobile terminal from his bag or pocket and takes the terminal out, the ringtone is maximized. It is annoying around you. At present, the owner is conscious of this and presses the incoming call button to make a call.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
An embodiment of the invention described in (1) will be described with reference to FIG. 1A shows a block diagram, and FIG. 1B shows an operation flow. In the present embodiment, a mobile terminal (for example, a mobile phone) incorporates a human detection sensor 1 for detecting the movement of a person within a predetermined range in a non-contact manner, and the mobile terminal detects that there is an incoming call via an antenna (ANT). The microcomputer in the terminal (control unit
CPU 2), and when a person (the hand, etc.) approaches the above range at the time of the detection, the microcomputer 2 enters the same call state as when the incoming call button is pressed down, and the call channel (T
CH) is established.

The human detection sensor 1 is set so as to detect when a person approaches a portable terminal from several cm to 10 cm. Since the human detection sensor 1 detects the movement of a person, it is not detected even if the person is always nearby without moving, but is detected when the person moves nearby.

As shown in FIG. 1 (b), the operation flow from the incoming call to the establishment of the communication channel in this embodiment is as follows.
An incoming call is detected by the microcomputer 2 (step S1).
2) Incoming call notifying means (not shown) performs a predetermined incoming call notifying operation. That is, for example, a ringer sounds a ringing tone or a vibrator,
It turns on (or blinks) an indicator light such as an LED.

By such an incoming call notifying operation, a person tries to answer the telephone, and the hand of the person approaches the portable terminal. Then, in steps S13 and S14, it is determined whether or not the human detection sensor 1 has been set and whether or not the sensor 1 has detected a human movement.

As a result, if the human sensor 1 is set, and the human sensor 1 detects the movement of a human hand and is detected via the interface of the microcomputer 2, the microcomputer 2 proceeds to step S15. Control is performed to the same call state as when the incoming call button is pressed down. This allows the user to answer the phone without touching the mobile terminal.

Therefore, when an incoming call is received while driving a car, the incoming call can be received simply by touching the portable terminal without having to search for and press down the incoming call button while driving. Because it is possible, it is possible to make a call simply by bringing the portable terminal to the ear, and it is safe. In particular, a portable terminal that supports hands-free is even more secure.

As a result of the determination in steps S13 and S14, if the human detection sensor 1 is not set, or if it is set but no human movement is detected,
When the person presses down the incoming call button in step S16, the microcomputer 2 enters the talking state. In this case, it is dangerous to search for the incoming call button during driving, for example.

Next, an embodiment of the present invention will be described with reference to FIG. 2, the same parts as those in FIG. 1 are denoted by the same reference numerals, (a) is a block diagram, and (b) is an operation flow.

In this embodiment, a portable terminal (for example, a portable telephone) incorporates a human detection sensor 1 for detecting the movement of a person within a predetermined range in a non-contact manner, and an incoming call is received via an antenna (ANT). This can be done by using the microcomputer (control unit,
The microcomputer 12 controls the ringer drive amplifier 13 to reduce the sound of the ringer 14 when a person (hand or the like) approaches the above range at the time of the detection,
Thereafter, a call is made by depressing an incoming call button.

As shown in FIG. 2B, an operation flow from an incoming call to a telephone call in this embodiment is as follows. First, when there is an incoming call in the portable terminal in step S21, the incoming call is detected by the microcomputer 12 (step S22). ), Microcomputer 1
2 controls the ringer drive amplifier 13 to increase the ringer sound emitted by the ringer 14 (step S23).

Then, the person who hears this ringer sound tries to answer the telephone, and the hand of the person approaches the portable terminal. Then, in steps S24 and S25, it is determined whether or not the human detection sensor 1 has been set and whether or not the sensor 1 has detected a human movement.

As a result, if the human sensor 1 is set and the human sensor 1 detects the movement of the human hand and is detected via the interface of the microcomputer 12, the microcomputer 12 proceeds to step S26. The ringer drive amplifier 13 is controlled so that the ringer sound of the ringer 14 is reduced.

For this reason, when the user presses the incoming call button to answer the mobile phone in step S27, the ringer sound has already been reduced, and the surroundings will not be disturbed. Therefore, if there is an incoming call in the bag or when the call is placed in the chest pocket, the ringer sound will already be heard when searching for the portable terminal in the bag or pocket by hand. When the mobile terminal goes outside, the ringer will ring with a loud sound and will not bother others.

If the result of the determination in steps S24 and S25 is that the human detection sensor 1 has not been set or has been set but has not detected the movement of a person,
As in step S28, the ringer sound remains at the set large level, and when the portable terminal is taken out of a bag, pocket, or the like, the ringer sound disturbs the surroundings. When controlling the ringer sound from large to small,
It can be reduced rapidly, gradually reduced, or set freely.

Further, as another embodiment of the present invention, when a motion of a person is detected by the human detection sensor 1, not only the ringer sound of the incoming call is reduced but also the ringer sound is stopped. It may be configured to switch to vibrator drive (set to vibrator mode), turn on or blink a 10-key LED, or combine them.

The present invention can be applied not only to a mobile phone but also to other mobile terminals such as a PHS and a cordless phone.

[0027]

As described above, according to the present invention, the following excellent effects can be obtained. (1) With the portable terminal according to the first aspect of the invention, if there is an incoming call while driving a car, let's touch the portable terminal without searching for an incoming call button while driving You can answer the phone by simply saying, "You can just call the mobile device in your ear and talk."

[0028] For this reason, it is possible to answer the telephone without any danger such as searching for an incoming call button while driving, and it is safe. Further, if hands-free is supported, when an incoming call is received, a call can be received and a telephone call can be made simply by touching the portable terminal, which is more secure.

At present, many accidents occur while using a portable terminal while driving a car, which is a social problem. By applying the present invention, many accidents can be prevented.

(2) With the portable terminal according to the second to sixth aspects of the present invention, when there is an incoming call in a bag, when the terminal is to be taken out of the bag or the like, Since the human detection sensor detects the hand searching for the mobile terminal in the bag,
The ringer sound can be reduced in a very short time after an incoming call.

For this reason, when the portable terminal is taken out of the bag, the ringer sound is already low, and it is possible to answer the call without disturbing the surroundings even in a busy state. This eliminates the hassle of having to urgently depress the incoming call button because the loud ringer sounds when the portable terminal is taken out of the bag.
