FIG. 4 is a block diagram showing a circuit configuration.
The same components as those described in FIGS. 1 to 3 are denoted by the same reference numerals. At the time of the incoming call, the signal received by the antenna 121 is subjected to repair such as demodulation by the receiving section of the wireless communication circuit section 41, processed as an audio signal by the audio processing section 42, and output to the receiver 21. Further, the control unit (control I)
C) 28 recognizes the incoming call and performs an incoming call operation.

The volume of the ringing tone emitted from the receiver 21 at the time of an incoming call is automatically adjusted by the ringing tone generation controller 43 based on a command from the controller (control IC) 28 and output to the receiver 22. Specifically, at the time of an incoming call, the control unit (control IC) 28 controls the optical sensor 25 and the brightness level determination unit 4.
4 is operated, and information on the brightness around the mobile phone detected by the optical sensor 25 is compared with a set value previously set in the operation unit 114 by the brightness level determination unit 44,
The comparison result is taken into the control unit (control IC) 28. The control unit (control IC) 28 automatically instructs the volume of the ring tone emitted from the ring tone generation control unit 43 based on the comparison result. If the preset value is not exceeded (when the surroundings are dark), an instruction is given to generate a loud ringing tone. If the preset value is exceeded (when the surroundings are bright), a low volume tone is issued. Instruct the user to ring.

This is because when the surroundings are dark, it is often put in a bag or the like, and it is necessary to increase the volume in order to notify the incoming call in this state. On the other hand, when the surroundings are bright, the mobile phone is often taken out of a bag or the like and placed on a desk or the like. In this case, the mobile phone is often located at a position where the mobile phone can be visually recognized.

FIG. 5 is a side view of the portable telephone shown in FIG. 1 mounted on a mounting surface with its lighting opening on the mounting surface side.
FIG. 6 is an enlarged plan view seen from the antenna side in FIG. The same components as those described in FIGS. 1 to 3 are denoted by the same reference numerals. 5 and 6, 30
Denotes a flat mounting surface (table, desk, etc.). As shown in the figure, the mobile phone housing 10 has its lighting opening 1
Even when the mounting surface 12 is set on the mounting surface 30 and the mounting surface 30 is placed on the mounting surface 30, the lighting opening 112 is far from the mounting surface 30. There is no. Therefore, the control unit 28 instructs to emit a ringing tone at a small volume.

When carrying a portable telephone, it is common to carry a portable telephone in a bag-like container instead of a bag.

FIG. 7 shows the portable telephone of FIG.
It is a sectional side view when it is put in 0. 1 to 3
The same components as those described in (1) are denoted by the same reference numerals. In this case, it is natural that the antenna is stored with the antenna 121 facing upward. In this case, since the display unit 113 side is heavy, it tends to fall down to the display unit 113 side as shown in the figure. Since the protruding portion 11 b abuts on 40 and the lighting opening 112 is separated from the mounting surface 30, the lighting opening 112 is not blocked by the bag-like container 40. Therefore, the light 50 from above does not easily reach the optical sensor disposed inside through the lighting opening 112. For this reason, the mobile phone properly detects that it is in the container, and the control unit 28 instructs to emit a loud ringing tone. Therefore, in any state, the brightness around the telephone body can be detected more accurately.

[0019]

According to the present invention, it is possible to obtain a portable telephone capable of more accurately detecting the situation where the portable telephone is placed, and thus reliably controlling the ringing tone upon receiving a call.
