Means 5 and audio output means 6 are provided as main components.

The antenna A is the same as that used in a conventional mobile phone, and is a thin string-shaped so-called string antenna (filament antenna) having both high convenience and high radio wave capturing ability. It is said. The antenna A is housed in an antenna housing (not clearly shown) provided on the side surface of the main body 1 like a conventional mobile phone antenna so as to be movable forward and backward.

As shown in FIG. 2, the main body 1 has a shape similar to that of a conventional mobile phone, and is small in size and light in weight, which is easy to carry in a palm size. Since the main body 1 has such a form, it can be carried without discomfort like a conventional mobile phone. Although not shown, the antenna housing is provided with a switch for detecting whether the antenna A is extended or housed in the antenna housing.

The input means 2 is disposed on the front of the main body 1, and has a main power switch 21, a number switch 22 provided in a conventional mobile phone, and a telephone mode (a state in which only telephone functions can be used). The radio wave sensing mode switch 23 switches from the radio wave sensing mode (a state in which the function of the radio wave detector cannot be used) to a radio wave sensing mode (a state in which only the function of the radio wave detector can be used, and the function of the telephone cannot be used for transmission and reception). It is composed of

The main power switch 21 is, for example, a push button switch. The main power switch 21 is kept pressed for a few seconds so that it does not come into contact with other portable items while being carried, so that the main power switch 21 of the mobile phone D with a radio wave sensing function is operated. While the power is turned on and the telephone mode is set to enable the transmission and reception of telephone calls, while the main power is on, the main power is turned off by holding down the main power switch 21 for several seconds.

The number switch 22 is designed to allow input of kanji and kana by mode switching in the same manner as a conventional mobile phone, and when the radio wave sensing mode switch 23 is set to the radio wave sensing mode, It also functions as an operation switch described later. Although not shown, various keys provided on the conventional mobile phone, such as a function key and a transmission key, are also provided.

The radio wave sensing mode switch 23 is an automatic reset type slide switch which is turned on by, for example, sliding upward with a finger, and automatically returns downward when the finger is released. When the power switch 23 is turned on, the main power is switched from the telephone means 4 to the radio wave sensing means 3 and when the same operation is performed in the radio wave sensing mode as described above, the main power is turned off due to security and the telephone is turned off. Neither the mode nor the radio sensing mode is activated.

The main power is not turned on even when the radio wave sensing mode switch 23 is operated in a state where the power is not turned on.

The radio wave sensing means 3 is built in the main body 1 and, as shown in FIG. 1, an amplifier 31 for amplifying radio waves intercepted by the antenna A, and a radio wave amplified by the amplifier 31 is used for a mobile phone. And a band-pass filter 32 for selecting a frequency band excluding a specific frequency band such as a frequency band being used, a frequency band used for parent and child telephones (specifically, 800 MHz, 1500 MHz, and 1900 MHz).

Here, the radio wave intensity determination unit 33 determines whether the background state (level 1), the state near the voyeur or eavesdropper (level 2), or the state near the voyeur or eavesdropper (level). 3) is determined. When the antenna A is extended, a direction in which radio waves are transmitted, that is, a direction in which a voyeur or eavesdropping device is located is detected. The direction in which the voyeur or eavesdropping device is located is detected, for example, by swinging the mobile phone D with a radio wave sensing function and searching for the direction in which the radio wave level is the highest.

The radio wave sensing means 3 having such a configuration is realized by appropriately combining a band-pass filter, a radio wave intensity determiner, and a command signal output device conventionally used in a radio wave detector and a radio wave detector. it can. Note that a specific frequency elimination filter that eliminates a specific frequency may be used instead of the bandpass filter 32.

The telephone means 4 is built in the main body 1, and is specifically a circuit for transmitting and receiving telephones, e-mails and the like provided in a conventional mobile telephone. The specific configuration is the same as that of a known device, and a detailed description thereof will be omitted.

The display means 5 is similar to a display screen used for a conventional mobile phone, and is, for example, a liquid crystal display screen.

In the display unit 5, in the telephone mode, a display indicating that the telephone mode is set is displayed, and the telephone number of the currently called party or the telephone number of the called party is displayed in the same manner as the conventional mobile phone. While the display of the number and the text of the e-mail to be transmitted and received are displayed, in the radio wave sensing mode, the indication of the radio wave sensing mode is displayed and the following display is made. That is,

(1) If a radio wave search is being performed, a predetermined moving image indicating that the search is being performed is displayed.

(2) If the level is 1, a predetermined moving image or the like that indicates that there is no voyeur or eavesdropping machine and that it is safe is displayed.

(3) In the case of level 2, a predetermined moving image or the like indicating that there is a voyeur or eavesdropper nearby is displayed.

(4) At level 3, if the antenna A is in the extended state, an arrow indicating the direction in which radio waves are transmitted, that is, the direction in which a voyeur or eavesdropper is installed, is displayed. If A is in the stowed state, the specific countermeasures described in the instruction manual, such as the procedure for finding the voyeur or eavesdropping machine, and the contact information to the distributor are displayed in text.

In addition to the above, it is also possible to display which function each number switch of the number switch 22 is to operate, or to display the operation procedure and the next operation to be performed. Good. When such a display is made, there is no need to memorize the operation method or operate while looking at the instruction manual, and the operation becomes easier.

The voice output means 6 outputs a ringtone or the voice of the other party during a call in the telephone mode as in the case of a conventional mobile phone, while in the radio wave sensing mode, for example, During the radio wave exploration, music is played, and in the case of level 3, a predetermined sound such as sounding an alarm is output.

Next, a method for avoiding eavesdropping or eavesdropping by using the mobile phone D with a radio wave sensing function having the above configuration will be described.

(1) Hold down the main power switch 21 for several seconds to turn on the main power and set the telephone mode. As a result, the display unit 5 displays the telephone mode.

(2) In the telephone mode, if the radio wave sensing mode switch 23 is turned on for a few seconds, the radio sensing mode is set, and the display means 5 indicates that. At the same time, the display means 5 also displays an explanation of what function each number switch 22 is used for. For example, a display such as "1: start of radio wave detection" and "2: radio wave direction display" is also made.

(3) With the antenna A extended, at a place where voyeurism or eavesdropping is concerned, for example, at a place 5 to 10 m away from a changing room (hereinafter referred to as a target place), set “1” of the number switch 22 to “1”. Push. Thereby, the radio wave sensing operation is started. During the radio wave sensing operation, a moving image indicating the operation is displayed on the display means 5 and a predetermined music is played from the audio output means 6. When the music stops, the display on the display means 5 is checked. At this time, if a moving image indicating level 1 is displayed, the level at this time is set as the background level.

(4) With the antenna A pulled out at the target location in the same manner as in (3), press “1” of the number switch 22 to check the radio wave condition at the target location. In this case, turn the antenna A in each direction and check whether the radio wave intensity increases. Even in this case, if the moving image displayed on the display means 5 is of level 1, it can be determined that no voyeur or eavesdropping device is installed nearby.

(5) If the moving image displayed on the display means 5 in (4) is of level 2, since a voyeur or eavesdropping machine is installed nearby, the direction of the antenna A at that time is considered. Estimate where the voyeur or eavesdropping machine is located. Until the radio wave condition reaches the background level, the evacuation direction is evacuated in the opposite direction to avoid the eavesdropping or eavesdropping.

(6) If the moving image displayed on the display means 5 in (4) is of level 3, it indicates that a voyeur or eavesdropping machine is near, and the audio output means 6 An alarm sounds. When "2" of the number switch 22 is pressed, an arrow indicating the direction in which the radio wave is transmitted is displayed on the display means 5. At this time, if evacuation is performed in the direction opposite to the direction indicated by the arrow, voyeurism or eavesdropping can be avoided.

(7) In the case of (6), the antenna A is housed in order to find a voyeur or eavesdropping machine. Then, a procedure for searching for a voyeur or eavesdropper is displayed on the display means 5. Follow the instructions to search for a voyeur or eavesdropper and remove the voyeur or eavesdropper. Thereby, voyeur or eavesdropping can be reliably prevented.

(8) If it is confirmed that there is no voyeur or eavesdropping machine, the radio power sensing mode switch 23 is turned on for a few seconds to turn off the main power.

As described above, since the mobile phone with the radio wave sensing function of the first embodiment integrates the function with the radio wave sensor into the mobile phone, it is necessary to carry both the mobile phone and the radio wave sensor. User convenience is improved. In addition, since the function with the radio wave detector is integrated into the mobile phone, it is possible to check for a voyeur or eavesdropping device at the location before using the mobile phone. In addition, the radio wave intensity of the detected radio wave is notified in three levels of level 1, level 2 and level 3 by moving image display and sound for each level, and the direction of radio wave transmission is indicated by an arrow. Since the operating method is displayed, the approximate distance to the voyeur or the eavesdropping machine or the direction in which the voyeur or the eavesdropping machine is installed can be grasped, and countermeasures can be easily taken. In addition, reliability is high because there are few malfunctions due to radio waves from other mobile phones.

It is assumed. The calculation of the direction in which the eavesdropping device is located by the DTMF sound comparison / calculator 84 is performed using the maximum value of the DTMF sound stored in the DTMF sound storage unit 85.

The number switch 22 of the input means 2 is provided with a switch for switching to the DTMF mode in addition to the switch used in the first embodiment. For example, the switch “3” is a switch for switching to the DTMF mode.

The display means 5 performs the operation procedure of radio wave detection, the explanation of the function of the number switch 22, the display of the mode, and the like by using a moving image or a text as appropriate in the same manner as that described in the first embodiment. For example, a display such as "3: switch to DTMF mode" is performed.
