DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable radio telephone.

[0002]

2. Description of the Related Art In a conventional portable radio telephone, a ringing tone at the time of an incoming call sounds at a preset volume level. In addition, when a response key is pressed at the time of an incoming call, a communication state is established, or when a response hold key is pressed, a response hold state is set.

When the amount of light detected by the optical sensor is equal to or less than a predetermined value, a pen-type paging receiver provided with a sound inhibiting means for inhibiting the generation of a reception notification sound is disclosed in Japanese Utility Model Application Laid-Open No. 2-123.
No. 141 discloses this.

[0004]

The conventional portable radio telephone is designed to make a ringing tone sound at a preset volume level when an incoming call is received. For example, if the sound is stored in a closed space such as the inside of a bag and the volume of the ringing sound is set high in advance so that the ringing sound can be heard even when the sound is stored, the sound is taken out of the bag and opened. There was a problem that the ringing tone was too loud when disturbing the surrounding area. In addition, when the light amount detected by the optical sensor is equal to or less than a certain value, in the case of a pen-type paging receiver having a sound prohibition unit that prohibits the generation of a reception notification sound, the reception notification at the time of use at night is used. There is a problem that the sound may not sound.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, a portable radio telephone 1 according to the present embodiment has an input unit 110 for setting and inputting one of a plurality of response modes at the time of an incoming call, an optical sensor 101 for detecting a light receiving amount at the time of an incoming call, and An A / D converter (hereinafter, A / DC) 102 that converts an analog signal output from the optical sensor 101 into a digital signal, a ring tone oscillator 105 that generates a ring tone, and a ring volume from the ring tone oscillator 105. An electronic volume 104 that varies the ring volume according to a volume control signal from the control unit 103, an amplifier 106 that amplifies the output of the electronic volume 104, a sounder 107 that sounds a ring tone by the output of the amplifier 106, and a base station (shown in FIG. A wireless unit 108 for transmitting and receiving a wireless signal relating to a call to the mobile phone 1 (not shown); A memory 109 for storing a control program and the like for the entire portable telephone 1 and the whole of the portable telephone 1 are controlled in accordance with the program stored in the memory 109, and a change in the amount of received light is determined based on an output signal of the A / DC 102 at the time of incoming call. And a control unit 103 for outputting a volume control signal for determining and controlling the volume level of the ringing tone in accordance with an increase or decrease in the amount of received light.

FIG. 2 is a flowchart showing an operation procedure of the ringing volume judgment of the control unit at the time of an incoming call in the present embodiment.

Next, the operation of this embodiment at the time of an incoming call will be described with reference to FIGS. When portable wireless telephone (hereinafter referred to as telephone) 1 of the present embodiment detects an incoming call while in a bag, control unit 103 controls wireless unit 108.
When it is determined from the received signal from the electronic device and the own number in the memory 109 that the incoming call has been received, the electronic volume 1
A ringer is sounded from the sounder 107 at an initial ringer volume level set in advance in step 04 (S11).

Next, when the user hears the ringing tone and takes out the telephone 1 from the bag, the optical sensor 101 receives ambient light, and the analog signal from the optical sensor 101 is A / D.
The signal is converted into a digital signal by C102 and
Is input to The control unit 103 determines from the input digital signal whether the received light amount has changed from an initial set value and determines that the telephone 1 has been taken out of the bag (S12). If it is set or read from the memory 109 (S13), and the answer mode is set to talk or hold, the control unit 103 stops the output to the ring tone oscillator 105 (S14).
Automatically set to call or hold mode.

If the mode is set to the free mode, it is determined whether or not the change in the amount of received light due to the digital signal is decreasing (S15). It is determined whether it is above or not (S16). If it is equal to or more than the predetermined value, it is determined that the ringing volume level should be set to a set value lower than the initial level (S17).

In this case, the control unit 103 sends a volume control signal to be set lower than the initial level to the electronic volume 104 to lower the volume of the ringing tone from the sounder 107.

That is, when the telephone 1 is put out of the bag brightly, the volume of the ringing tone decreases.

If it is determined in S15 that the amount of received light has decreased, it is determined whether the decrease in the amount of received light is equal to or less than a predetermined constant value (S18). It is determined that the set value should be higher than the level, and a volume control signal is sent to the electronic volume 104 to increase the ringing tone from the sounder 107 so as to be higher than the initial level.

If the increase or decrease in the amount of received light does not substantially change from a preset value, the ringing volume level is maintained at the initial level.

When the free mode is set, the control unit 103 detects that the call from the input unit 110 or the hold button is pressed, and the ringing tone oscillator 1
The output of the ringing tone from 05 is stopped.

FIG. 3 is a flowchart showing the operation procedure of the control unit after the end of a call in this embodiment.

Next, the operation of the present embodiment after the end of a call will be described with reference to FIGS.

The control unit 103 detects that the call end button from the input unit 110 has been pressed (S21), and detects that the telephone 1 is stored in the bag and that the amount of received light has changed by the optical sensor. (S22). Electronic volume 104
Ringer sounds at a preset initial level
7 is set to sound and return to the original state. That is, there is no need to manually adjust the ringer level to the initial level.

[0023]

As described above, according to the present invention, one of a plurality of response modes at the time of an incoming call is set in a portable radio telephone which is carried in a closed space in a pocket, bag or the like. and setting means, mode of automatic response in advance setting means
When set to Talk mode, when a call is taken out of a closed space into an open space such as a pocket or bag when an incoming call is received, a change in the amount of received light is detected and the ringing tone is automatically stopped, and the telephone is in a call state. a call means for, the motor of the pre-free state setting means
If it is set to the mode, when it is taken out of the closed space to the open section at the time of incoming call, the change of the received light amount is detected and the ringing tone level is automatically changed to the lower one, and when it is stored in the closed space again, the original volume By providing a volume level varying means for automatically varying the level, for example, when an incoming call is received in a public such as a train, the setting means is set to a free mode in advance.
When the mode is set to the mode, the ringing tone level can be automatically lowered when the user gets out of the bag or the like, so that there is an effect that it is possible to avoid disturbing the surroundings.

Further, it is possible to eliminate the trouble of lowering the ringing tone when taking out from a bag or the like, the trouble of setting up a telephone call, and the trouble of resetting the original ringing sound level when storing the same in the bag again. There is an effect that can be done.
