Abstract

PROBLEM TO BE SOLVED: To provide a portable terminal which does not bother people around with an incoming signaling tone and also improves operability at a dark place. SOLUTION: A touch sensor 1 is attached to a body side of a portable telephone and a detection signal of the sensor is supplied to a CPU 2. The CPU 2 receives a detection signal when a hand, etc., of a person touches the sensor 1 and supplies a drive stop signal to a ringer driving circuit 3 which generates a ringer tone or a vibration driving circuit 4 which drives a vibrator (or both the circuits) if the portable telephone is in the process of receiving. Also, when the portable telephone is in a waiting state, a drive (lighting) signal is supplied to a back light driving circuit 5 of an LCD of a displaying part and a key LED driving circuit 6 of a key operating part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a portable telephone, a PH
S, a portable terminal such as a cordless telephone.

[0002]

2. Description of the Related Art Conventional portable terminals, for example, portable telephones,
At the time of an incoming call (calling), an incoming call alerting sound (ringing sound) such as a bell or a ringer or an incoming call notifying operation such as vibrating a vibrator is performed. When the user recognizes the incoming call as described above, some buttons such as an incoming call button are depressed to bring the telephone into a talking state.

[0003]

A conventional portable telephone is
During an incoming call, the bell ringing operation and vibrator operation cannot be stopped unless some button is pressed. Therefore, the ringing operation of the bell continues from the time of the incoming call to the time when the button is pressed, causing great trouble to the surrounding people.

[0004] In addition, whether the call is received or in a standby state,
If you do not press any button, LC which is the liquid crystal display
Since the backlight of D and the illumination of the key LED and the like did not light up, it was very inconvenient when operating in a dark place.

[0005] The present invention has been made in view of the above points, and has as its object to provide a portable terminal which does not disturb the surrounding people by the incoming call notification sound and has improved operability in a dark place. Is to do.

[0006]

According to the present invention, a touch sensor provided on a main body of a portable terminal, and whether or not there is an incoming call when the touch sensor detects a contact is determined. And a control unit for stopping the incoming call notifying operation when the incoming call has not been received as a result of the determination.

(2) At the time of an incoming call, a person's hand or the like simply touches the touch sensor. If an incoming call is being made, the ringing of the bell for informing of the incoming call is stopped. As a result, the ringing time of the bell is extremely short, so that the surrounding people are not annoyed. Further, when the touch sensor detects the contact and there is no incoming call and the apparatus is in a standby state, the LCD display portion and the operation key portion are turned on, so that it is easy to see and the operability is improved.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 1 denotes a touch sensor attached to a main body surface, for example, a side surface of a mobile terminal such as a mobile phone. Reference numeral 2 denotes a CPU (microcomputer) that receives a detection signal when a hand or the like comes into contact with the touch sensor 1 and stops an incoming call notification operation or turns on a display operation unit according to the state of the mobile phone.

That is, if the portable telephone is ringing when the contact is sensed, a drive stop signal is sent to the ringer drive circuit 3 for generating a ringer sound or the vibrator drive circuit 4 for driving the vibrator (or both circuits). Supply, and when the mobile phone is in the standby state,
The drive (lighting) signal is supplied to the backlight drive circuit 5 of the CD and the key LED drive circuit 6 of the key operation unit.

As shown in FIG. 2, the touch sensor 1 connects one electrode 1a of a pair of electrodes 1a and 1b arranged at a predetermined interval to each other via a resistor 7 with a control power supply (not shown).
B), and a common connection point between the electrode 1a and the resistor 7 is connected to the CPU 2. When a human hand or the like touches the electrodes 1a and 1b of the touch sensor 1 across the electrodes, a current flows from the control power source to the ground via the resistor 7, the electrodes 1a and 1b and the human hand, and the resistor 7 and the electrode 1a Of the common connection point changes.
Is for recognizing contact of the human hand.

Next, the operation of the portable telephone constructed as described above will be described with reference to the flowchart of FIG. First, when a human hand or the like touches the touch sensor 1 in step S1, the CPU 2 recognizes the contact by the operation described in FIG. 2, and determines in step S2 whether the mobile phone is in a standby state.

As a result, if it is in the standby state, the CPU 2
Sends a lighting control signal to the backlight driving circuit 5 and the key LED driving circuit 6 to turn on the lighting (step S3). If the result of the determination is that the ringer is not in a standby state (for example, an incoming call is being received), it is determined in step S4 whether the ringer is driven.

As a result, when the ringer is driving, C
The PU 2 sends a drive stop signal to the ringer drive circuit 3 to stop the ringer (step S5). If the ringer is not driven, it is determined in step S6 whether the vibrator is driven.

As a result, if the vibrator is being driven, the CPU 2 sends a drive stop signal to the vibrator driving circuit 4 to stop the vibrator (step S7).

If it is determined in step S2 that the vehicle is not in the standby state, the driving of the ringer and the vibrator may be stopped at the same time.

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

[0017]

(1) As described above, according to the first and second aspects of the present invention, the time during which the incoming notification sound is sounding can be extremely shortened. For this reason, when receiving a call in a place where there are many people, such as in a train or in crowds, hold the mobile phone in your hand to remove it from your bag, inside your inner pocket, etc. The bell sound stops at the moment when you hear it, so you won't bother others.

(2) According to the second aspect of the present invention, the lighting is turned on at the moment of holding the portable telephone in the dark, such as at night, so that the key location and the LCD are easy to see, and the operability is improved. Is significantly improved.
