DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a perspective view showing an embodiment of the appearance of a mobile communication portable terminal device according to the present invention. FIG. 1 (a) is a partially broken view, and FIG. 1 (b) is a user holding and swinging it down. It is a figure which shows a state.
The mobile terminal device main body 1 has a receiver 5, a display 7, a keypad 12, and a transmitter 6.
A shock sensor 3 as a response sensor is built in the lower part of the mobile terminal device body 1.
[0007]
The shock sensor 3 detects the acceleration of the mobile terminal device body 1 by moving one contact by the acceleration when the acceleration is applied and contacting the other contact.
An erroneous response prevention touch sensor 2 is embedded at the boundary between the front surface and the side surface on which the keypad 12 is provided.
The touch sensor 2 is formed by embedding four conductors in the outline of the mobile terminal device body 1 and exposing the end portion thereof. When the user 9 holds the mobile terminal device body 1 as shown in FIG. The resistance value between the conductors is a value close to a short circuit.
[0008]
FIG. 2 is a block diagram showing an embodiment of a circuit of the mobile communication portable terminal device of FIG.
The shock sensor 3 and the false response prevention touch sensor 2 are connected to a hook control unit 23 which is a part of the function of the protocol control device 24.
The wireless transmission / reception unit 26 is connected to the protocol control device 24 via the wireless interface unit 25.
[0009]
When making a call, the user presses the off-hook button on the keypad to shift to the outgoing state and presses the other party's phone number. The protocol control unit 24 sends the other party telephone number to the wireless transmission / reception unit 26 via the wireless interface unit 25. The radio transmission / reception unit 26 emits a carrier wave modulated by the other party telephone number and other information from the antenna 8.
On the other hand, when there is an incoming call, the call information is demodulated by the wireless transmission / reception unit 26 and input to the protocol control device 24 via the wireless interface unit 25. When the protocol control device 24 recognizes that it is a call of itself from the call information, it outputs a call signal from a speaker (not shown).
[0010]
Usually, a user can answer a call by pressing an off-hook button.
However, for example, when a call is received while driving a car, it is expected that it is difficult to press the off-hook button. In such a case, the user holds the mobile terminal device body 1 and responds by swinging it down.
In a state where the user does not hold the mobile terminal device body 1, the false response prevention touch sensor 2 does not output a detection signal, so the hook control unit 23 performs control so as not to accept a detection signal from the shock sensor 3. . This is to prevent the response signal from being erroneously transmitted when an acceleration of a certain value or more is applied to the mobile terminal device body 1 due to vehicle vibration or the like and the shock sensor 3 detects it.
[0011]
When the user holds the mobile terminal device body 1, the conductors of the false response prevention touch sensor 2 are in a substantially short-circuited state, and the hook control unit 23 can accept a detection signal from the shock sensor 3. In this state, as shown in FIG. 1B, when the user 9 swings down in the direction indicated by the arrow A and gives an acceleration of a certain level or more, the shock sensor 3 outputs a detection signal. The hook control unit 23 generates a response signal and sends it to the wireless transmission / reception unit 26 via the wireless interface unit 25. The radio transmission / reception unit 26 emits a carrier wave modulated by the response signal from the antenna 8, and the base station can know the response of the called mobile terminal device.
FIG. 3 is a perspective view showing another embodiment of the present invention.
In this example, a touch sensor 11 is provided as a response sensor at the bottom of the mobile terminal device. A push button 10 is provided as an erroneous response prevention sensor.
[0012]
FIG. 4 is a block diagram showing an embodiment of a circuit of the mobile communication portable terminal device of FIG.
Since the touch sensor 11 is used as the response sensor, it is considered that the touch sensor 11 is accidentally touched while holding the mobile terminal device. Therefore, when the function of the present invention is not used, the erroneous response prevention push button 10 is pressed. It is off. Thereby, the hook control unit 27 performs control so as not to accept the detection signal from the touch sensor 11.
For example, when the portable terminal device is placed on a car seat and the function of the present invention is used, the erroneous response prevention push button 10 is pressed to be turned on. The hook control unit 27 can accept a detection signal from the touch sensor 11.
When the user touches the lower part of the portable terminal device and touches the touch sensor 11 by the call signal, a detection signal is sent to the hook control unit 27.
[0013]
5A and 5B are diagrams showing a reference example of the present invention, in which FIG. 5A is a perspective view showing a state when responding by infrared rays, and FIG. 5B is a circuit diagram showing an outline of the circuit. In this example, an infrared receiver 14 for receiving a specific coded infrared ray is provided at the lower part of the portable terminal device 18, and a specific coded infrared ray emitted by the infrared transmitter 15 is received to respond to an incoming call (call). It is what you do.
When the push button 16 of the infrared transmitter 15 is pressed as shown in FIG. 5B, the control unit 12 drives the light emitting unit 22 by the push button signal. The light emitting unit 22 emits a specific coded infrared ray, and the infrared receiving unit 14 of the mobile terminal device 18 detects the specific coded infrared ray. Thus, the hook control unit 20 outputs a response signal.
[0014]
In the case of FIG. 5, for example, when an exercise bike is performed in a fitness club, the portable terminal device 18 cannot be worn, so the portable terminal device 18 is placed on a nearby chair or bench 19 or the like. . In this case, a thin small infrared transmission device 15 is attached to the wrist with a band, and when a call is made, a response can be made by pressing the push button 16 of the infrared transmission device 15 toward the portable terminal device 18. Once responding, the calling terminal can wait without giving up on the way. Thus, the user can temporarily stop the exercise bike, go to the chair, bench 19 and the like, pick up the portable terminal device 18 and talk.
Thus, when a situation arises in which a mobile terminal device must be placed at a position slightly distant from the user (within 7 m for infrared rays), it is very convenient and can easily respond to an incoming call.
[0015]
In the above embodiment, the shock sensor is used as one of the response sensors. However, a gyro sensor may be used to detect acceleration in the same manner as this. It is configured to the one moved much advance in numbers (eg acceleration 100), in which the acceleration to output a detection signal when it becomes 100 or more.
In addition, when a shock sensor or a gyro sensor is used as a response sensor, not only can it be shaken down, but a shock can be applied in the same manner, so that a response can be detected. The response sensor may be one that detects a certain frequency or more.
Further, a rubbing detection sensor that responds to rubbing with a finger or the like in contact can be used as a response sensor. This is to detect that the capacitance position changed by moving the finger in this state is changed by embedding a conductor in a part of the outline of the mobile terminal device 18 and changing the capacitance by bringing the finger closer to it. It is.
It is also possible to use radio waves instead of infrared rays.
[0016]
