Description

  The present invention relates to a receiving device that receives radio waves, such as a portable terminal device, a television receiver, and a radio receiver.

  When the electric field strength of the radio wave transmitted from the base station and reaching the mobile phone is high, the mobile phone can receive the radio wave transmitted from the base station. On the other hand, for example, when the distance between the base station and the mobile phone is long and the electric field intensity of the radio wave reaching the mobile phone is small, the mobile phone may not be able to receive the radio wave transmitted from the base station.

  In a mobile phone in which the relative position between the housing and the antenna, such as a pull-out type whip antenna, is variable, the antenna is pulled out of the housing rather than being housed in the housing. The reception sensitivity of the antenna is higher. In a conventional mobile phone, when the electric field strength of the radio wave reaching the mobile phone is small, the relative position between the antenna and the housing is detected, and when the antenna is housed in the housing, a warning sound is generated by a warning generating means. Or the antenna is automatically pulled out of the housing by the antenna driving means. When the user who has heard the warning sound pulls out the antenna from the casing, or automatically pulls out the antenna from the casing by the antenna driving means, the reception sensitivity of the antenna can be increased. By increasing the reception sensitivity of the antenna, radio waves transmitted from the base station can be received even when the electric field strength of the radio waves arriving from the base station is small (see, for example, Patent Document 1).

  For example, in a mobile phone in which the relative position between the housing and the antenna is variable, even if the antenna is pulled out of the housing, if there is an object that absorbs radio waves such as a hand near the antenna, the base station The radio wave transmitted from the mobile phone is absorbed by the object, and there is a problem that the electric field strength of the radio wave received by the portable telephone is lowered. In addition, the presence of the object in the vicinity of the antenna has a problem that antenna characteristics such as antenna directivity and input impedance change. If the antenna directivity changes from the directivity designed in advance, there is a possibility that radio waves transmitted from the base station cannot be received. Further, when the input impedance of the antenna changes from the predesigned input impedance, the impedances of the antenna and the feeder line do not match, and the return loss increases. As a result, there is a problem that the reception sensitivity of the mobile phone is lowered. In particular, when the antenna is built in the housing, there is a high possibility that the periphery of the antenna is covered with an object that absorbs radio waves such as a hand, and the reception sensitivity of the mobile phone is lowered.

  FIG. 2 is a front view showing the mobile terminal device 1. FIG. 3 is a rear view showing the mobile terminal device 1. FIG. 4 is a side view showing the mobile terminal device 1. The mobile terminal device 1 includes a first housing 30 and a second housing 31. The first housing 30 and the second housing 31 are each formed of a hollow plate-like body and have a substantially rectangular parallelepiped shape. A hinge portion 32 is formed including one longitudinal end of the first housing 30 and one longitudinal end of the second housing 31, and the first housing 30 and the second housing 31 are relatively angular. The mobile terminal device 1 is configured to be foldable so that the mobile terminal device 1 can be folded. When the mobile terminal device 1 is in a folded state, the display unit is exposed such that the display screen 38 of the display unit 20 is exposed from the one surface portion 33 in the thickness direction facing the second housing 31 of the first housing 30. 20 is provided in the first housing 30. In addition, when the mobile terminal device 1 is folded, the operation keys 22 are second so that the operation keys 22 are exposed from the one surface 34 in the thickness direction facing the first housing 30 of the second housing 31. Provided in the housing 31.

  The antenna portion 2 is an intermediate portion between both ends in the short direction perpendicular to the longitudinal direction and the thickness direction of the second casing 31 and is formed near one end portion in the longitudinal direction, that is, near the hinge portion 32. The antenna unit 2 has a substantially rectangular parallelepiped shape, is built in the internal space of the hollow second housing 31, extends from one end portion in the short direction of the second housing 31 to the other end portion, and And the relative position is fixed.

  On the display screen 38 of the display unit 20, an electric field strength display region in which the electric field strength of the radio wave captured by the antenna unit 2 is displayed in a plurality of stages according to the magnitude of the signal power Pant generated by the electric field strength detector 4. 39 is provided. When the electric field intensity of the radio wave captured by the antenna unit 2 is small and cannot communicate with the communication equipment of the base station, the characters “out of service area” are displayed in the electric field intensity display area 39.

  Each infrared sensor 35 can detect infrared rays emitted from the human body and infrared rays reflected by the human body. Since the infrared sensor 35 is configured to detect infrared rays having a wavelength emitted from the human body, it is difficult to detect an object other than the human body. Each infrared sensor 35 can detect infrared rays emitted from each infrared sensor 35 from a human body or the like existing within a predetermined third distance L3 in the other thickness direction of the second casing 31. The predetermined third distance L3 is selected from 1 mm to 10 mm, for example. Depending on which infrared sensor 35 of the plurality of infrared sensors 35 detects infrared rays emitted from an obstacle such as a hand, the object detection unit 17 places the hand or the like within a predetermined range of the antenna unit 2.

For example, when all the infrared sensors 35 constituting the object detection unit 17 detect infrared rays, it can be seen that the antenna unit 2 is covered by a hand or the like from the other side in the thickness direction of the second housing 31. For example, when a part of the infrared sensor 35 constituting the object detection unit 17 detects infrared rays, an obstacle such as a hand exists near the infrared sensor 35 that detects infrared rays, and the antenna unit 2 is It can be seen that part of it is covered.

  Since the predetermined first distance L1 and second distance L2 are selected to be approximately the thickness of a finger, when the antenna unit 2 is covered with a finger, the object detection unit 17 has the antenna unit 2 covered with the finger. It can be reliably detected.

  Hereinafter, the operation of the mobile terminal device 1 in the case where the electric field intensity of the radio wave arriving at the antenna unit 2 from the communication equipment of the base station is weak and the antenna unit 2 is covered by a user's hand or the like will be described.

  The user of the mobile terminal device 1 inputs and sets the setting information from the information input unit 11 to select and set a method for notifying warning information. When setting information is input from the information input unit 11, the setting information is stored in the storage unit 10. For example, when warning information is notified by visible information, the warning display unit 23 is set as a method for notifying warning information. When two or more of the warning display unit 23, the warning sound generation unit 24, and the warning vibration unit 25 are desired to notify the warning information, the warning display unit 23, the warning sound generation unit 24, Alternatively, two or more of the warning vibration units 25 may be selected and set. The selection unit is realized including the information input unit 11, the control unit 15, and the storage unit 10.

When power is supplied from the power supply unit 21 to each unit of the mobile terminal device 1, the process proceeds from step a0 to step a1.

  In step a1, the electric field intensity detection unit 4 is controlled to acquire the signal power Pant representing the electric field intensity of the signal wave captured by the antenna unit 2, and the process proceeds to step a2. In step a2, the threshold power Pth stored in advance in the ROM of the control unit 15 is compared with the signal power Pant. If the threshold power Pth is smaller, the process proceeds to step a1.

  In step a2, the threshold power Pth is compared with the signal power Pant. If the threshold power Pth is larger, the process proceeds to step a3.

  In step a3, the object detection unit 17 is controlled to acquire position information including information indicating whether an obstacle such as a hand is detected within a predetermined range of the antenna unit 2, and the process proceeds to step a4. In step a4, based on the position information, it is determined whether an obstacle such as a hand is detected within a predetermined range of the antenna unit 2, and if no obstacle such as a hand is detected, the process goes to step a1. Move.

If an obstacle is detected in step a4, the process proceeds to step a5.
In step a5, warning information is notified to the user by a method preset by the user among the warning display unit 23, the warning sound generation unit 24, and the warning vibration unit 25, and the process proceeds to step a1.

  When warning information is notified to the user by the warning display unit 23, for example, character information such as “WARNING” is displayed on the display unit 20. When warning information is notified to the user by the warning sound generation unit 24, a sound is generated from the voice output unit 6. A sound for notifying warning information can be distinguished from a ringing sound when there is an incoming call, for example, by setting different sound patterns in advance. When warning information is notified to the user by the warning vibration unit 25, the warning vibration unit 25 vibrates the mobile terminal device 1. The vibration for notifying the warning information and the ringing vibration when there is an incoming call, for example, can be distinguished by setting different vibration patterns in advance.

  When the user operates the information input unit 11 so that the control unit 15 controls the power supply unit 21 to finish supplying power to each unit of the mobile terminal device 1, the operation process of the control unit 15 ends.

  The notification unit 16 notifies the user of the warning information, thereby allowing the user to recognize that there is an obstacle such as a hand that hinders radio wave capture within a predetermined range around the antenna unit 2. The obstacle can be urged to move out of a predetermined range around the antenna unit 2. When the obstacle is moved out of the predetermined range around the antenna unit 2, a part of the radio wave to be captured by the antenna unit 2 is not absorbed by the obstacle and is captured by the antenna unit 2. A reduction in the electric field strength of the radio wave to be suppressed can be suppressed, and a change in antenna characteristics can be suppressed. As a result, radio waves to be captured can be captured more accurately, radio waves including information can be received, and a decrease in reception sensitivity of the receiving means can be suppressed. In addition, a part of the radio wave transmitted from the antenna unit 2 is not absorbed by the obstacle, and the change in the characteristics of the antenna unit 2 is suppressed, so that a predetermined radio wave is transmitted to the communication equipment of the base station. Therefore, it is possible to suppress the electric power necessary for this.

  Further, when the signal power Pant representing the electric field strength of the signal wave captured by the antenna unit 2 is larger than the predetermined threshold power Pth, even if an obstacle such as a hand exists within the predetermined range of the antenna unit 2, The receiving means can accurately receive the radio wave transmitted from the communication equipment of the base station to the mobile terminal device 1. Therefore, when the signal power Pant is larger than the threshold power Pth, it is not necessary to notify the user of the warning information even when the object is detected by the object detection unit 17, and the signal power Pant is the threshold power. When it is larger than Pth, warning information is not notified to the user. When the signal power Pant is larger than the threshold power Pth, the warning information is not notified to the user, so that the user removes an obstacle such as a hand existing within a predetermined range of the antenna unit 2 from the antenna unit 2. This saves you the trouble of moving away from the camera.

  When the warning information is set to be notified to the user by at least any two of the warning display unit 23, the warning sound generation unit 24, and the warning vibration unit 25, the warning information is displayed in the warning display unit 23, the warning sound generation unit 24, and Compared with the case where one of the warning vibration units 25 notifies the user, the warning information can be notified to the user more reliably.

  Further, when the user selects at least one of the warning display unit 23, the warning sound generation unit 24, and the warning vibration unit 25 and sets the warning information to be notified to the user by the selected method, the user The warning information can be notified by a desired method, and convenience can be improved. For example, when the user is deaf, even if warning information is notified by the warning sound generation unit 24, there is a possibility that the information notified by the user may not be recognized. It is desirable to notify the warning information by at least one of them.

  Each infrared sensor 35 of the mobile terminal device 1 according to the embodiment of the present invention is provided with a first interval L1, and the first interval L1 is selected to be, for example, 10 to 20 mm. The interval L1 is not limited to 10 to 20 mm, and the accuracy of detecting a human body or the like increases as the interval decreases. In step a2, the threshold power Pth is compared with the signal power Pant. If the threshold power Pth is smaller, the process proceeds to step a1, but before the process proceeds to step a1, the signal is greater than the threshold power Pth. Information indicating that the power Pant is larger may be notified to the user by the notification unit 16, and the information may be notified, and then the process may proceed to step a <b> 1. In step a4, based on the position information, it is determined whether an obstacle such as a hand is detected within a predetermined range of the antenna unit 2, and if no obstacle such as a hand is detected, step Although it is assumed that the process proceeds to a1, before the process proceeds to step a1, the user confirms that the signal power Pant is smaller than the threshold power Pth and that there is no obstacle such as a hand within a predetermined range of the antenna unit 2. The information to be represented may be notified to the user by the notification unit 16, and the information may be notified before the process proceeds to step a1.

  FIG. 8 is a block diagram showing a configuration of a mobile terminal device 40 according to still another embodiment of the present invention. The mobile terminal device 40 has the same configuration as the mobile terminal device 1 described above, and includes a comparison operation unit 41 in addition to the configuration of the mobile terminal device 1. Since the portable terminal device 40 of this Embodiment is the structure similar to the above-mentioned portable terminal device 1, about the corresponding part, the same referential mark is attached | subjected and the overlapping description is abbreviate | omitted. The mobile terminal device 40 includes an antenna unit 2, an RF unit 3, an electric field strength detection unit 4, an audio input unit 5, an audio output unit 6, an audio processing unit 7, a storage unit 10, an information input unit 11, a memory card interface unit 12, The imaging unit 14, the information processing unit 13, the control unit 15, the notification unit 16, the object detection unit 17, the display unit 20, the comparison calculation unit 41, and the power supply unit 21 are configured.

  When the antenna unit 2 is covered with a hand or the like, the magnitude of the signal power Pant detected by the electric field intensity detection unit 4 is smaller than when the antenna unit 2 is not covered. The amount by which the signal power Pant is reduced by covering the antenna unit 2 with a hand or the like depends on how the hand or the like covering the antenna unit 2 is covered. Information indicating a decrease amount of the signal power Pant according to how to cover the hand or the like covering the antenna unit 2 is described as reception characteristic information. Specifically, the reception characteristic information is information representing a decrease amount of the signal power Pant when the predetermined infrared sensor 35 detects infrared rays among the plurality of infrared sensors 35 configuring the object detection unit 17. This reception characteristic information is stored in the memory card 26. The memory card 26 is inserted into the memory card interface unit 12 by the user. The memory card interface unit 12 reads the reception characteristic information stored in the memory card 26, and the read reception characteristic information is stored in the storage unit 10. The reception characteristic information represents the amount by which the electric field strength of the radio wave captured by the antenna unit 2 is reduced due to the presence of an obstacle such as a hand.

  The comparison calculation unit 41 compares the position information of an obstacle such as a hand within the predetermined range of the antenna unit 2 detected by the object detection unit 17 with the reception characteristic information. The position information is information indicating where an obstacle such as a hand exists around the antenna unit 2, and the reception characteristic information is information when the obstacle such as a hand is at a predetermined position of the antenna unit 2. , Information indicating the decrease amount of the signal power Pant. The comparison calculation unit 41 compares the position information with the reception characteristic information, and the amount of change in the signal power Pant when the hand within the predetermined range of the antenna unit 2 is moved away from the antenna unit 2. A certain recovery amount α is predicted and generated. The value obtained by adding the signal power Pant and the recovery amount α is a signal power that is predicted to be detected by the electric field strength detection unit 4 after the hand or the like within the predetermined range of the antenna unit 2 is moved away from the antenna unit 2.

When the recovery amount α is smaller than a predetermined amount, the warning information is not notified.

  The notification unit 16 notifies the user of the warning information, so that the user has an obstacle such as a hand that hinders the capture of radio waves within a predetermined range around the antenna unit 2. When the distance between the antenna unit 2 and the antenna unit 2 is increased, the signal power Pant is recognized to be larger than the predetermined amount. It can be urged to move outside. When the obstacle is moved out of the predetermined range around the antenna unit 2, a part of the radio wave to be captured by the antenna unit 2 is not absorbed by the obstacle and is captured by the antenna unit 2. It is possible to suppress a decrease in the electric field strength of the radio wave, and to suppress a change in antenna characteristics. As a result, radio waves to be captured can be captured more accurately, radio waves including information can be received, and a decrease in reception sensitivity of the receiving means can be suppressed. In addition, a part of the radio wave transmitted from the antenna unit 2 is not absorbed by the obstacle, and the change in the characteristics of the antenna unit 2 is suppressed, so that a predetermined radio wave is transmitted to the communication equipment of the base station. Therefore, it is possible to suppress the electric power necessary for this.

  When the recovery amount α is smaller than a predetermined amount, a signal indicating the electric field strength of the signal wave captured by the antenna unit 2 even if an obstacle such as a hand existing within the predetermined range of the antenna unit 2 is moved away. Since the power Pant does not recover much, when the recovery amount α is smaller than a predetermined amount, warning information is not notified to the user. When the recovery amount α is smaller than the predetermined amount, warning information is not notified to the user, so that the user removes an obstacle such as a hand existing within a predetermined range of the antenna unit 2 from the antenna unit 2. Save time and effort.

In step d2, the threshold power Pth stored in the ROM of the controller 15 is compared with the signal power Pant. If the threshold power Pth is smaller, the process proceeds to step d1.

  In step d2, the threshold power Pth is compared with the signal power Pant. If the threshold power Pth is larger, the process proceeds to step d3.

To step d4. In step d4, the value obtained by adding the signal power Pant and the recovery amount α is compared with the threshold power Pth. If the threshold power Pth is smaller, the process proceeds to step d1. The value obtained by adding the signal power Pant and the recovery amount α is the signal power that is predicted to be detected by the electric field strength detection unit 4 after the hand or the like within the predetermined range of the antenna unit 2 is moved away from the antenna unit 2. It is.

  In step d4, the value obtained by adding the signal power Pant and the recovery amount α is compared with the threshold power Pth. If the threshold power Pth is larger, the process proceeds to step d5.

  In step d5, the warning information is notified to the user by a method preset by the user among the warning display unit 23, the warning sound generation unit 24, and the warning vibration unit 25, and the process proceeds to step d1.

  When the user operates the information input unit 11 so that the control unit 15 controls the power supply unit 21 to finish supplying power to each unit of the mobile terminal device 40, the operation process of the control unit 15 ends.

  The notification unit 16 notifies the user of the warning information, so that the user has an obstacle such as a hand that hinders the capture of radio waves within a predetermined range around the antenna unit 2. To recognize that the signal power Pant is expected to be larger than the threshold power Pth when the antenna unit 2 is moved out of the predetermined range of the antenna unit 2, and the obstacle is moved out of the predetermined range around the antenna unit 2. Can be moved. When the obstacle is moved out of the predetermined range around the antenna unit 2, a part of the radio wave to be captured by the antenna unit 2 is not absorbed by the obstacle and is captured by the antenna unit 2. It is possible to suppress a decrease in the electric field strength of the radio wave, and to suppress a change in antenna characteristics. As a result, radio waves to be captured can be captured more accurately, radio waves including information can be received, and a decrease in reception sensitivity of the receiving means can be suppressed. In addition, a part of the radio wave transmitted from the antenna unit 2 is not absorbed by the obstacle, and the change in the characteristics of the antenna unit 2 is suppressed, so that a predetermined radio wave is transmitted to the communication equipment of the base station. Therefore, it is possible to suppress the electric power necessary for this.

  Further, when the value obtained by adding the signal power Pant and the recovery amount α is smaller than the threshold power Pth, the antenna unit 2 captures even if an obstacle such as a hand existing within a predetermined range of the antenna unit 2 is moved away. Since the signal power Pant representing the signal wave to be recovered does not recover up to the threshold power Pth, warning information is not notified to the user in this case. When the value obtained by adding the signal power Pant and the recovery amount α is smaller than the threshold power Pth, the user is not notified of the warning information, so that the user has a hand existing within a predetermined range of the antenna unit 2 or the like. The trouble of moving the obstacle away from the antenna unit 2 can be saved.
