The touch panel 2 is disposed over substantially the entire front surface 1A. The input unit 3 and the first microphone 8 are disposed at one end in the longitudinal direction of the front surface 1A. The 1st receiver 7 and the shielding state detection part 4 are arrange | positioned adjacent to the other edge part of the longitudinal direction of the front 1A. That is, the first receiver 7 and the first microphone 8 are disposed at both ends in the longitudinal direction. The shielding state detection unit 4 detects whether or not the display unit 2B (touch panel 2) formed on the same surface is in a shielding state and outputs a detection signal. As will be described later, the shielding state detection unit 4 can be configured by a proximity sensor, for example, and can detect that the display unit 2B is in a shielding state when the proximity of an object is detected.

  Since the housing 20 has a single box shape, the surface of the touch panel 2 (display unit 2B, touch sensor 2A) is constantly exposed and is not hidden by the housing 20.

  The touch panel 2 is provided on the front surface 1A, displays characters, figures, images, and the like, and performs various operations performed on the touch panel 2 using a finger, stylus, pen, or the like (hereinafter referred to as “indicator”). To detect. Note that the touch panel 2 may detect any operation such as an electrostatic capacity type or a pressure sensitive type. The input unit 3 includes a plurality of buttons such as a button 3A, a button 3B, and a button 3C to which a predetermined function is assigned.

The display unit 2B includes, for example, a liquid crystal display (LCD), an organic EL (Organic Electro-Luminescence) panel, and displays characters, graphics, and the like.

  The input unit 3 receives a user operation through the physical buttons 3 </ b> A to 3 </ b> C and transmits a signal corresponding to the received operation to the control unit 10. The power supply unit 5 supplies power obtained from the storage battery or the external power supply to each functional unit of the mobile phone terminal 1 including the control unit 10 according to the control of the control unit 10.

  The communication unit 6 establishes a radio signal line by a CDMA system or the like with a base station via a channel assigned by the base station, and performs telephone communication and information communication with the base station. The 1st receiver 7 outputs the audio | voice signal transmitted from the control part 10 as an audio | voice. The first microphone 8 converts a user's voice into a voice signal and outputs the voice signal to the control unit 10.

  The shielding state detection part 4 can be comprised with a proximity sensor, for example. The proximity sensor is a measuring instrument that measures a distance from an object in a predetermined direction. The proximity sensor is disposed on the front surface 1A of the housing 20 and emits measurement waves such as infrared rays, ultrasonic waves, and laser light, and the reception portion is disposed on the front surface 1A of the housing 20 and receives the measurement waves. And the reception unit receives the measurement wave that is emitted from the transmission unit and reflected by the target object. The proximity sensor determines the distance between the proximity sensor and the target object based on the intensity of the measurement wave received by the reception unit, the incident angle of the measurement wave, the time from transmission by the transmission unit to reception by the reception unit, etc. calculate. When the proximity sensor detects proximity of an object with the proximity sensor, the shielding state detection unit 4 outputs a detection signal indicating that the display unit 2B (touch panel 2) is in a shielding state to the control unit 10.

  The RAM 11 is used as a storage area for temporarily storing instructions of a program executed by the control unit 10, data referred to by the control unit 10, calculation results of the control unit 10, and the like.

  The storage unit 9 is, for example, a nonvolatile memory or a magnetic storage device, and stores programs and data used for processing in the control unit 10. The program stored in the storage unit 9 includes an OS (not shown) that realizes basic functions of the mobile phone terminal 1, a device driver (not shown) for hardware control of the device, a mail program 9A, a browser A program 9B, a display notification control program 9C, a power control program 9D, and the like are included. The storage unit 9 also stores other programs and data such as address book data. The storage unit 9 may be configured as a combination of a portable storage medium such as a memory card and a storage medium reading device.

  The mail program 9A provides a function for realizing an electronic mail function. The browser program 9B provides a function for realizing a WEB browsing function. The display notification control program 9C provides a function for realizing a function for notifying an event generated by a function such as another program by a screen display or other means and a function for controlling the display of the display unit 2B. The power control program 9D provides a function for realizing a power control function including a power saving mode.

  The control unit 10 is, for example, a CPU (Central Processing Unit), a microprocessor, a DSP, and the like, and implements various functions by comprehensively controlling the operation of the mobile phone terminal 1. Specifically, the control unit 10 executes instructions included in the program stored in the storage unit 9 while referring to the data stored in the storage unit 9 and the data expanded in the RAM 11 as necessary. Various functions are realized by controlling the display unit 2B, the communication unit 6, and the like. Note that the program executed by the control unit 10 and the data to be referred to may be downloaded from the server device by wireless communication by the communication unit 6.

  For example, the control unit 10 implements an e-mail function by executing the mail program 9A. Further, the control unit 10 executes a display notification control program 9C, thereby providing a function of notifying an event generated by a function of another program or the like by a screen display or other means and a function of controlling the display of the display unit 2B. Realize the function to realize. Moreover, the control part 10 implement | achieves the function which controls the electric power supply from the power supply part 5 to each part of the mobile telephone terminal 1 by running the power control program 9D. Note that the control unit 10 can execute a plurality of programs in parallel by a multitask function provided by the OS.

  In addition, when there is no input operation for a certain period from the touch panel 2, the input unit 3, or the like, the control unit 10 shifts to the low power consumption mode and reduces the power consumption. In the low power consumption mode, the control unit 10 performs power saving control of each unit including power saving control of the touch panel 2 (for example, turning off the display unit 2B and turning off the touch sensor 2A). The control unit 10 turns off the shielding state detection unit 4 when there is no input operation for a certain period.

  For example, when the electronic device 1 is in a bag or pocket, the display unit 2B is covered with something, or placed on a desk or the like with the front surface 1A of the housing facing, the user displays The screen of part 2B cannot be seen (cannot be operated). In such a situation, when an event that is not caused by a user operation (for example, incoming mail, voice incoming call, alarm report sound, etc.) occurs in the low power consumption mode, the low power consumption mode is canceled, Displaying the display unit 2B and the like consumes wasted power because the user does not use the mobile phone terminal 1 but the low power consumption mode is canceled. Therefore, in the present embodiment, when the control unit 10 is in the low power consumption mode and an event that does not result from a user operation occurs, the shielding state detection unit 4 and the display unit 2B are in the shielding state. Is detected, control for maintaining the low power consumption mode is performed.

  FIG. 5 is a flowchart for explaining an example of processing when the control unit 10 is in the low power consumption mode. In FIG. 5, it is assumed that the electronic device 1 is in a low power consumption mode (the display unit 2B is turned off and the touch sensor 2A is turned off). First, the control unit 10 determines whether an event (for example, incoming mail, incoming voice call, alarm, etc.) not caused by a user operation has occurred (step S1). When an event not caused by a user operation has occurred (“Yes” in step S1), the control unit 10 activates the shielding state detection unit 4 (step S2), and determines whether the display unit 2B is in the shielding state. Is detected (step S3). When the detection of the shielding state detection unit 4 ends, the control unit 4 turns off the shielding state detection unit 4.

  When the display unit 2B is in the shielding state (“Yes” in step S4), the control unit 10 maintains the low power consumption mode (maintains the display unit 2B being turned off and the touch sensor 2A being turned off). Audio output from the first receiver 7 and audio input from the first microphone 8 are enabled (step S5). On the other hand, when the display unit 2B is not in the shielding state (“No” in step S4), the control unit 10 cancels the low power consumption mode (turns on the display unit 2B and turns on the touch sensor 2A). The voice output of the first receiver 7 and the voice input of the first microphone 8 are enabled (step S6).

  Although the shielding state detection unit 4 is arranged on the front surface 1A of the housing 20, it may be arranged on the rear surface 1B. In this case, when the shielding state detection unit 4 does not detect the proximity of the object, the display unit 2B detects that the shielding state is present.

  As described above, according to the present embodiment, the housing 20, the display unit 2 </ b> B disposed on the first surface (front surface) 1 </ b> A of the housing 20, and the surface thereof exposed, A shielding state detection unit 4 that is arranged and capable of detecting whether or not the display unit is in a shielding state, and a control unit 10 that controls the power of the mobile phone terminal 1 and executes the low power consumption mode, When the display unit 2B detects that the display unit 2B is in the shielding state when an event that is not caused by the user operation occurs in the low power consumption mode, Since the mode is maintained, even if an event occurs when the display unit 2B is in a shielded state (hidden state), unnecessary power consumption can be reduced by maintaining the low power consumption mode. Is possible.

  In addition, when the control unit 10 is in the low power consumption mode and an event that is not caused by a user operation occurs, the control unit 10 activates the shielding state detection unit 4, so that the shielding state detection unit 4 generates an event. It is possible to reduce the power consumption of the shielding state detection unit 4 by starting up only when it is performed.

  In addition, since the low power consumption mode includes at least the low power control of the display unit 2B, it is possible to reduce the power of the display unit with high power consumption.

  In addition, since the event not caused by the user operation is at least one of voice incoming call, mail incoming call, and alarm, the power consumption is reduced when there is a voice incoming call, mail incoming call, alarm, etc. It becomes possible to do.

  In addition, when the shielding state detection unit 4 is arranged on the first surface (front) 1A of the housing 20 and the proximity of an object is detected, the display unit 2B is detected to be in the shielding state. In the configuration in which the detection unit 4 is disposed on the first surface (front surface) 1A of the housing 20, it is possible to detect the shielding state of the display unit 2B.

  Further, since the shielding state detection unit 4 is arranged on the second surface (back surface) 1B of the housing and the proximity of the object is not detected, it is determined that the display unit 2B is in the shielding state. In the configuration in which the shielding state detection unit 4 is disposed on the second surface (back surface) 1B of the housing 20, it is possible to detect the shielding state of the display unit 2B.

  Although the proximity sensor is used as the shielding state detection unit 4 in the first embodiment, a luminance sensor may be used to detect the shielding state of the display unit 2B. Further, a proximity sensor and a luminance sensor may be used in combination.

In FIG. 8, the same number is attached | subjected to the step which performs the process equivalent to FIG. In FIG. 8, it is assumed that the mobile phone terminal 1 is in a low power consumption mode (the display unit 2B is turned off and the touch sensor 2A is turned off). First, the control unit 10 determines whether an event (for example, incoming mail, incoming voice call, alarm, etc.) not caused by a user operation has occurred (step S1). When an event not caused by a user operation has occurred (“Yes” in step S1), the control unit 10 activates the shielding state detection unit 4 (step S2), and determines whether the display unit 2B is in the shielding state. Is detected (step S3). As a result of this detection, when the display unit 2B is in the shielding state (“Yes” in step S4), the control unit 10 maintains the low power consumption mode (the display unit 2B is turned off and the touch sensor 2A). The second display unit 12 is turned on, the voice output from the second receiver 13 is enabled, and the voice input from the second microphone 14 is enabled (step S11). On the other hand, when the display unit 2B is not in the shielding state (“No” in step S4), the control unit 10 cancels the low power consumption mode (turns on the display unit 2B and turns on the touch sensor 2A). The voice output of the first receiver 7 is enabled, and the voice input of the first microphone 8 is enabled (step S12).

  As described above, according to the second embodiment, the second display unit 12 is provided on the second surface (rear surface) 1B of the housing 20, and the control unit 10 is in the low power consumption mode.

(Embodiment 3)
With reference to FIG.9 and FIG.10, the mobile telephone terminal 1 which concerns on Embodiment 3 is demonstrated. The appearance configuration of the mobile phone terminal 1 of the third embodiment is the same as that of the second embodiment. FIG. 9 is a block diagram of the mobile phone terminal 1 according to the third embodiment. 9, parts having the same functions as those in FIG. 7 are denoted by the same reference numerals, description of common parts is omitted, and only different points will be described.

  As shown in FIG. 9, the mobile phone terminal 1 according to Embodiment 3 has a configuration in which an attitude detection unit 30 is added to the configuration of Embodiment 2 (FIG. 7). The posture detection unit 30 detects whether the front surface 1A of the housing 20 is in the first posture facing the upper side in the vertical direction or whether the front surface 1A is in the second posture facing the lower side in the vertical direction. The detection is output to the control unit 10. That is, it is detected whether the front surface 1A of the housing 20 is placed facing upward or facing downward.

  The attitude detection unit 30 is a detector that detects the attitude of the mobile phone terminal 1, specifically, the attitude of the housing 20.

In FIG. 10, it is assumed that the mobile phone terminal 1 is in a low power consumption mode (the display unit 2B is turned off and the touch sensor 2A is turned off). First, the control unit 10 determines whether an event (for example, incoming mail, incoming voice call, alarm, etc.) not caused by a user operation has occurred (step S1). When an event not caused by a user operation has occurred (“Yes” in step S1), the control unit 10 activates the shielding state detection unit 4 (step S2), and determines whether the display unit 2B is in the shielding state. Is detected (step S3). As a result of this detection, when the display unit 2B is not in the shielding state (“No” in step S4), the control unit 10 cancels the low power consumption mode (turns on the display unit 2B and turns on the touch sensor 2A). ), Audio output from the first receiver 7 is enabled, and audio input from the first microphone 8 is enabled (step S26).

  On the other hand, when the display unit 2B is in a shielded state (“Yes” in step S4), the control unit 10 activates the posture detection unit 30 to detect the posture of the mobile phone terminal 1 (step S22). When the detection of the posture detection unit 30 is completed, the control unit 4 turns off the posture detection unit 30. As a result of the detection, when the first posture (the front surface 1A of the housing 20 is vertically upward) is maintained, the control unit 10 maintains the low power consumption mode (the display unit 2B is turned off and the touch sensor). 2A is maintained), and the audio output of the first receiver 7 is set to be larger than that set (step S25). On the other hand, in the second posture (the front surface 1A of the casing 20 is vertically downward), the control unit 10 maintains the low power consumption mode (the display unit 2B is turned off and the touch sensor 2A is turned off). The state is maintained), the voice input from the first microphone 8 is suppressed, and the voice input from the second microphone 14 is enabled (step S24).

A posture detection unit 30 capable of detecting the second posture facing the side, and the control unit 20 is in a shielding state when an event not caused by a user operation occurs in the low power consumption mode. When the detection unit 4 detects that the display unit 2B is in a shielded state and the posture detection unit 15 detects the first posture, the sound output of the first receiver 7 is larger than that set. Therefore, when the display unit 2B is placed upward and the display unit 2B is shielded (for example, when paper or the like is placed on the display unit 2B), the first receiver 7 Increasing the audio output makes it easier for users to generate events You can inform the sure.

  Further, according to the third embodiment, the first microphone 8 disposed on the first surface (front surface) 1A of the housing 20 and the second microphone 14 disposed on the second surface (back surface) 1B of the housing 20. The control unit 10 detects that the display unit 2B is in the shielding state by the shielding state detection unit 4 when an event not caused by a user operation occurs in the low power consumption mode. Further, when the second posture is detected by the posture detection unit 30, the voice input from the first microphone 8 is suppressed and the voice input from the second microphone 14 is enabled. The voice input from the second microphone 14 is possible in a state where the unit 12 is placed upward.
