A mobile phone terminal to which is added will be described.

(Embodiment 1)
FIG. 4 is a block diagram showing a configuration of mobile phone terminal 100 according to Embodiment 1 of the present invention. Each structure which comprises the mobile telephone terminal 100 shown in FIG. 4 is demonstrated.

  The antenna 1 transmits and receives radio waves to and from the base station. The wireless unit 2 performs processing such as modulation / demodulation of radio waves. The control unit 3 controls each component and performs each operation described below. The input unit 4 includes operation keys and the like, and inputs signals to the mobile phone terminal 100 based on pressing of the operation keys by the user. The display unit 5 includes an LCD panel, an organic EL panel, and the like, and displays and notifies that there is a missed call or displays other information.

  The storage unit 6 is configured by RAM or the like, and stores conditions and the like used when the determination unit 11 determines. In the present embodiment, a first condition that “the output value of the placement sensor 9 is 0” and a second condition that “the output value of the touch sensor 10 is 1” are stored. In addition, incoming call information 14, missed call information 15 (see FIG. 11), and other various information are stored.

  The voice input / output unit 7 is a microphone or a speaker that inputs / outputs voice data to / from the outside of the mobile phone terminal 100. The notification unit 8 generates sound or vibration and notifies the user.

  As shown in FIG. 6, the placement sensor 9 includes a mover 12 and a switch 13. The display sensor 5 is in a state where the display unit 5 faces downward, or that the user visually recognizes display contents on the upper part of the display unit 5. Since there is an obstacle, it is detected that the mobile phone terminal 100 is placed in a state where the display unit 5 is hidden and cannot be seen by the user. In the case of a straight type mobile phone terminal having one display unit shown in FIG. 5A, the display unit 5 is arranged on the surface opposite to the display unit 5.

  For example, in FIG. 6 (a), since the mobile phone terminal 100 is placed so that the surface on which the placement sensor 9 is placed is in contact with the desk, the mover 12 receives a force from the desk in the direction of the arrow in the figure, It shows that the switch 13 is turned on. When the switch 13 is turned on, 1 is output to the control unit 3 as an output value indicating that the surface on which the placement sensor 9 is disposed is in contact with the desk.

  Further, in FIG. 6B, since the mobile phone terminal 100 is placed so that the surface opposite to the surface on which the placement sensor 9 is placed is in contact with the desk, the mover 12 is not subjected to force and the switch 13 shows that it is in an OFF state. When the switch 13 is in an OFF state, 0 is output to the control unit 3 as an output value indicating that the surface on which the placement sensor 9 is disposed is not in contact with the desk.

  When the detection part comes into contact with the user, the touch sensor 10 detects that the temperature of the contact part changes. When the temperature of the detection portion changes, 1 is output to the control unit 3 as an output value indicating that the user has touched, and when the temperature of the detection portion does not change, 0 is output as an output value indicating that the user is not touching Is output to the control unit 3.

  The detection portion is a hatched portion in FIG. 7 and is the entire outer surface of the casing of the mobile phone terminal 100. Thereby, it is possible to detect that the user has touched any part of the casing of the mobile phone terminal 100 that the user touches. Note that the contact here refers to, for example, touching the mobile phone terminal 100 without pressing the operation key of the input unit 4.

  The determination unit 11 determines whether the output of the placement sensor 9 satisfies the first condition stored in the storage unit 6, and the second condition in which the output of the touch sensor 10 is stored in the storage unit 6. It is determined whether it is satisfied, and it is further determined whether the missed call information 15 is stored in the storage unit 6.

  The incoming call information 14 is information related to incoming calls such as caller terminal information and incoming call date / time information.

  The missed call information 15 is information having the call information 14 and a flag 16 indicating that the user is not responding, and has a structure shown in FIG.

  Hereinafter, a method for storing a missed call when an incoming call is received will be described. FIG. 8 shows an example of an operation flow from when an incoming call is received until the missed call information 15 is stored. When the antenna 1 receives a radio wave from the base station (step A1), the display unit 5 displays that the incoming call has been received, and the notification unit 8 generates a sound, vibration or the like to notify the user that the incoming call has been received. The incoming operation is started (step A2).

  When the user responds by operating the input unit 4 during the incoming call operation (step A3), the process proceeds to step A7. In step A7, information related to the incoming call such as the caller side terminal information and the incoming call date and time information is stored in the storage unit 6 as the incoming call information 14. Thereafter, the missed call storage flow is terminated.

  If the user does not respond and the user operates the input unit 4 to respond to the incoming call and then the communication from the base station is disconnected due to a factor other than the disconnection (step A4), the process proceeds to step A5. The reason for the disconnection of communication is that the caller terminal or the mobile phone terminal 100 has been disconnected due to an operation from each user, the caller terminal or the mobile phone terminal 100 has entered an out-of-service area, etc. is there.

  In step A5, the incoming call operation is terminated, and the process proceeds to step A6. In step A6, a flag 16 indicating that the user is not responding to the incoming call is stored in the storage unit 6 as missed call information 15 together with information related to the incoming call such as the incoming terminal information and incoming date and time information. Thereafter, the missed call storage flow is terminated.

  Next, a method for notifying the user that there is a missed call will be described. FIG. 9 is an operation flow for notifying that there is a missed call when the mobile phone terminal receives a contact from the user when the missed call information 15 is stored in the storage unit 6.

  In step B <b> 1, the determination unit 11 determines whether the missed call information 15 is stored in the storage unit 6. When it is determined that it is not stored, the missed call notification flow is terminated, and when it is determined that it is stored, the process proceeds to step B4.

  In step B4, the determination unit 11 determines whether the output value of the touch sensor 10 satisfies the second condition. When the cellular phone terminal 100 receives a contact from the user on the detection portion, the contact detection sensor 10 detects a temperature change in the detection portion and outputs 1 as an output value indicating that the temperature has changed. In this case, the determination unit 11 determines that the second condition is satisfied, and proceeds to step B6. When the mobile phone terminal 100 does not receive a contact from the user on the detection portion, the contact detection sensor 10 does not detect a temperature change in the detection portion and outputs 0 as an output value indicating that the temperature does not change. In this case, the determination unit 11 determines that the second condition is not satisfied, and returns to Step B4.

  In step B6, the notification unit 8 generates a sound or vibration to notify the user that there is a missed call. Thereafter, the missed call notification flow is terminated.

  Further, a method for confirming a missed call upon receiving the above notification and deleting the flag 16 indicating that the user of the missed call information 15 is not responding will be described with reference to FIG. FIG. 10 is an operation flow from when the user confirms a missed call until the missed call information 15 is deleted.

  When the incoming call history button 20 which is one of the input units 4 shown in FIG. 7 is pressed by the user (step C1), the display unit 5 displays the missed call information 15 stored in the storage unit 6 (step C2). ). As a result, the user can confirm the contents of the missed call. Next, the process proceeds to step C3.

  In step C3, the flag 16 indicating that the user included in the missed call information 15 is not responding is deleted. Thereafter, the missed call confirmation flow is terminated.

  As described above, in the present embodiment, when there is an incoming call but the user does not answer, the missed call information 15 is stored in the storage unit 6, and the touch sensor 10 causes the mobile phone terminal 100 to contact the user. When it is detected that the notification has been made, the notification unit 8 performs notification.

  Accordingly, the user can know that there is a missed call by simply touching the mobile phone terminal 100 without looking at the display unit 5 that displays that there is a missed call. Further, since the notification is performed when the user touches the mobile phone terminal 100, the number of notifications can be reduced, the trouble to the surroundings can be alleviated, and the power consumption by the notification unit 8 can be reduced.

  Next, when the display unit 5 notifies the user that there is a missed call by displaying the display unit 5 as shown in FIG. 1, when the display unit 5 is not visible to the user and is touched by the user, The mobile phone terminal that the notification unit 8 notifies that there is an incoming call will be described below.

  FIG. 12 is an operation flow for notifying that there is a missed call when the display unit 5 is not visible to the user when there is a missed call and the mobile phone terminal 100 is touched by the user.

  In step B <b> 1, the determination unit 11 determines whether the missed call information 15 is stored in the storage unit 6. When it is determined that it is not stored, the missed call notification is terminated, and when it is determined that it is stored, the process proceeds to step B2.

  In step B2, the determination unit 11 determines whether the output of the placement sensor 9 satisfies the first condition. When the mobile phone terminal 100 is placed in a state where the display unit 5 is not visible to the user as shown in FIG. 6B, the placement sensor 9 is set to 0 as the output value because the switch 13 is in the off state. Output. In this case, the determination unit 11 determines that the first condition is satisfied, and proceeds to step B4.

  When the mobile phone terminal 100 is placed with the display unit 5 visible to the user as shown in FIG. 6A, the switch 13 is turned on and the placement sensor 9 outputs 0 as the output value. In this case, the determination unit 11 determines that the first condition is not satisfied, and ends the missed call notification flow. Since the operation after step B4 has been described above, it will be omitted.

  As a result, when the display unit 5 notifies the user that there is a missed call as shown in FIG. 1, the mobile phone terminal 100 is placed in a state invisible to the missed call display unit 5 user. When the placement sensor 9 detects that the mobile phone terminal 100 is in contact with the user, the notification unit 8 can notify that there is a missed call.

  12, it is determined whether the output value of the placement sensor 9 satisfies the first condition, and when it is determined that the first condition is satisfied, the output value of the temperature sensor 10 satisfies the second condition. Although described in the processing procedure of determining whether or not it is satisfied, the effect of the present invention can be obtained by notifying that there is a missed call only when both the first condition and the second condition are satisfied, regardless of the order of such determination. Can play.

  In addition to the straight type shown in FIG. 2 (a) described in the present embodiment, the folding type shown in FIG. 2 (b) as shown in FIG. 2 screen folding type having a main display portion used in the open state and a sub display portion used in the closed state as shown in FIG. 2B, and a folding type shown in FIG. As shown in FIG. 2D, there is a one-screen folding type or the like having only a main display portion used in the open state. Hereinafter, the arrangement of the placement sensor 9 for the mobile phone terminal of the one-screen folding type and the two-screen folding type will be described.

  In the case of the two-screen folding type, for example, as shown in FIG. Thus, when the mobile phone terminal 100 is placed in a state where the sub display unit 5 displaying that there is a missed call is not visible to the user, the placement sensor 9 is set to 0 because the switch 13 is turned off. Output. The storage unit 6 stores a condition that “the output value of the placement sensor 9 is 0” as the first condition, as in the present embodiment. Since the operation flow is the same as that of the present embodiment, a description thereof will be omitted.

  Also, in the case of the one-screen folding type or the two-screen folding type that cannot display that there is a missed call in the sub display unit 5, for example, as shown in FIG. Place it in a position where the switch turns on when it is closed. Thereby, the open / closed state of the mobile phone terminal can be detected. When the mobile phone terminal is in the closed state, the placement sensor 9 turns on the switch 13 and outputs 1. The storage unit 6 stores a condition that “the output value of the placing sensor 9 is 1” as the first condition. Since the operation flow is the same as that of the present embodiment, a description thereof will be omitted.

  The position where the placement sensor 9 is arranged is not limited to the above-described place, and may be arranged on the same surface as the display unit 5. In this case, since the switch 13 is turned on and 1 is output when the mobile phone terminal is placed with the display unit 5 hidden, the output of the placement sensor 9 is stored in the storage unit 6 as a first condition. The condition that the value is “1” may be stored.

  Further, in the present embodiment, the detection part of the touch sensor 10 is the entire outside of the casing including the input unit 4 and the display unit 5 of the mobile phone terminal 100. For example, the hatched portion in FIG. As shown by, the entire outside of the casing excluding the input unit 4 and the display unit 5 or a casing that is easily touched when the user holds the mobile phone terminal 100 as indicated by the hatched portion in FIG. It is good also as only the side.

  Further, an illuminance sensor that detects ambient brightness may be used as the placement sensor 9. The case where an illuminance sensor is used will be described below.

  An illuminance sensor is arranged at the position shown in FIG. 14 and the illuminance around the display unit 5 is detected. In each of the shapes shown in FIG. 14, when the mobile phone terminal is placed in a state where the display unit 5 that displays a missed call is not visible to the user, the illuminance sensor hits room light and detects the illuminance value of the room light. , Output the illuminance value. Conversely, when the mobile phone terminal is placed with the display unit 5 hidden, the illuminance sensor blocks room light and outputs an illuminance value lower than the illuminance value of the room light. Therefore, if the illuminance sensor is hardly exposed to room light, the illuminance value is, for example, 5 lux or less, and the first condition is “the output of the illuminance sensor indicates 5 lux or less”.

  When the first condition is satisfied and the touch sensor 10 detects that the user has touched, the missed call is notified. Since the operation flow is the same as that of the present embodiment, a description thereof will be omitted.

  Further, in the present embodiment, after the presence / absence of the missed call information 15 is determined, it is determined whether the detection values of the placement sensor 9 and the contact detection sensor 10 satisfy the conditions, but the placement sensor 9 and the contact detection sensor 10 are determined. The presence / absence of missed call information 15 may be determined after determining whether the detected value satisfies the condition. A case where the presence / absence of the missed call information 15 is determined after it is determined that the detection values of the placement sensor 9 and the touch sensor 10 satisfy the condition will be described.

  The operation flow from receiving an incoming call to storing the missed call information 15 is the same as in FIG. 8, and the operation flow until the user confirms the missed call and deletes the missed call is the same as in FIG. Description is omitted. A method for notifying the user that there is a missed call will be described. FIG. 15 is an operation flow for notifying the user that there is a missed call.

  In step D1, the placement sensor 9 detects the ambient illuminance value. In step D <b> 2, the determination unit 11 determines whether the illuminance value detected by the placement sensor 9 satisfies the first condition stored in the storage unit 6. When the cellular phone terminal 100 is placed as shown in FIG. 14, the placement sensor 9 is exposed to room light, and the illuminance value is the illuminance value of the room light. In this case, it is determined that the first condition “the output of the illuminance sensor is a value indicating 5 lux or less” is not satisfied, and the missed call notification flow is terminated. Further, when the mobile phone 100 is placed as shown in FIG. 3, the placing sensor 9 determines that the first condition is satisfied because the indoor sensor is not exposed to room light and the illuminance value is lower than the illuminance value of room light. The process proceeds to Step D3.

  In step D3, the touch sensor 10 detects a temperature change in the detection portion. In step D <b> 4, it is determined whether the output from the touch sensor 10 satisfies the second condition stored in the storage unit 6. When the detected portion comes into contact with the user, it is determined that the second condition is satisfied in order to detect a temperature change, and the process proceeds to Step D5.

  If the detected portion is not in contact with the user, the touch sensor 10 does not detect a temperature change, determines that the second condition is not satisfied, and returns to step D3.

  In step D <b> 5, the determination unit 11 determines whether the missed call information 15 is stored in the storage unit 6. If it is determined that it is stored, the process proceeds to step D6. When it is determined that it is not stored, the missed call notification flow is terminated.

  In step D6, the notification unit 8 generates a sound or vibration to notify the user that there is a missed call. Thereafter, the missed call notification flow is terminated.

  Further, in this embodiment, in order to determine whether or not the received call is a missed call, information regarding the missed call is stored in the storage unit 6 together with the flag 16 indicating that the user is not responding. Any method can be used as long as it can be determined whether or not it is an incoming call. For example, as shown in FIG. 11 (b), information related to an incoming call that the user has responded is stored together with a flag 17 indicating that the user has responded, and information related to a missed call is not responding as shown in FIG. 11 (c). It stores together with the flag 16 shown. Thereafter, when the user confirms the missed call, as shown in FIG. 11B, the flag 16 indicating that the user is not responding is changed to the flag 17 indicating that the user has responded, or as illustrated in FIG. In this way, the flag 18 indicating that the user has confirmed the missed call is further added to the missed call information 15 so that the missed call that has been confirmed can be distinguished from the missed call that has not been confirmed yet.

  In the present embodiment, a contact-type temperature sensor is used as the contact detection sensor 10, but any sensor may be used as long as it detects a situation outside the portable terminal. For example, a sensor that detects that the mobile phone terminal 100 is held by the user, a sensor that detects that the user has approached the mobile phone terminal 100, and the like are examples of detecting a situation outside the mobile terminal. .

  An inclination detection sensor can be considered as a sensor for detecting that the mobile phone terminal 100 is held by the user. In general, when a mobile phone terminal is placed at hand, the user usually holds it, puts it in a pocket, or puts it in a bag. Absent. However, when the mobile phone terminal is not used because it is not used, the user is often placed on a substantially horizontal object such as a desk and away from the mobile phone terminal.

  Therefore, when the mobile phone terminal is not in a substantially horizontal state, it is notified that there is a missed call, assuming that the user is nearby, such as being held by the user or being placed in a pocket.

  Hereinafter, a case where an inclination detection sensor is used as the contact detection sensor 10 will be described.

  The tilt detection sensor outputs 1 as an output value when it is placed in a horizontal state, and outputs 0 as an output value when it is placed in a state where it is tilted rather than horizontal.

  The tilt sensor is disposed inside the mobile phone terminal 100. When the mobile phone terminal 100 is placed substantially horizontally such as on a desk, the tilt detection sensor outputs 0 as an output value indicating that it is in a substantially horizontal state, and is not substantially horizontal because the user has it. In the state, the tilt detection sensor outputs 1 as an output value indicating that the sensor is not substantially horizontal.

  The second condition stored in the storage unit 6 is “the output value from the tilt detection sensor is 1.” Each operation flow when the tilt detection sensor is used as the contact detection sensor 10 is the same as the operation flow of the present embodiment, and thus the description thereof is omitted.

  When a tilt sensor is used as the touch sensor 10, when the mobile phone terminal 100 is placed on a substantially horizontal object such as a desk, it is not notified that there is a missed call, but on a substantially horizontal object. When not placed, it is possible to notify that there is a missed call. In addition, the configuration is easier than in the case where a temperature sensor is used as the contact detection sensor 10.

  Furthermore, as a sensor for detecting that the user has approached the mobile phone terminal 100, there is an RFID (Radio Frequency Identification) that performs short-range communication in a non-contact manner using an induction electromagnetic field or a radio wave.

  A case where RFID is used will be described. The RFID is composed of a reader / writer that constantly emits radio waves and an RF tag that transmits the radio waves and receives ID authentication data to the reader / writer. A reader / writer is built in the mobile phone terminal 100 as the touch sensor 10, and the user owns the RF tag separately from the mobile phone terminal 100.

  When the RF tag receives a radio wave emitted from the touch sensor 10, the RF tag receives the radio wave from the reader / writer and transmits data for performing ID authentication to the reader / writer. The reader / writer performs ID authentication with the received data, and detects whether this RF tag is an RF tag possessed by the user of the mobile phone terminal 100. The reader / writer outputs 1 as an output value to the determination unit 11 when the RF tag is owned by the user, and outputs 0 as the output value when the RF tag is not owned by the user.

  When the second condition stored in the storage unit 6 is “reader / writer output value is 1” and the reader / writer output value is 1, the determination unit 11 determines that the second condition is satisfied. Notification by the notification unit 8 is performed.

  Hereinafter, a method of notifying the user that there is a missed call when a reader / writer is used as the touch sensor 10 will be described with reference to FIG. FIG. 16 shows an example of an operation flow until the user is notified that there is a missed call. Steps E1 to E3 in FIG. 16 are the same operations as steps B1 to B3 in FIG.

  In step E <b> 1, the determination unit 11 determines whether the missed call information 15 is stored in the storage unit 6. When it is determined that it is not stored, the missed call notification flow is terminated, and when it is determined that it is stored, the process proceeds to step E2.

  In step E2, the determination unit 11 acquires the detection value of the placement sensor 9, and in step E3, determines whether the first condition is satisfied. When the mobile phone terminal 100 is placed in a state where the display unit 5 is not visible to the user, the placement sensor 9 outputs 0 as an output value. In this case, the determination unit 11 determines that the first condition stored in the storage unit 6 is satisfied, and proceeds to step E4. When the mobile phone terminal 100 is placed with the display unit 5 visible to the user, the placement sensor 9 outputs 1 as an output value. In this case, the determination unit 11 determines that the first condition is not satisfied, and ends the missed call notification flow.

  In step E4, the reader / writer receives data for performing ID authentication from the RF tag. In step E5, when data is received, the reader / writer performs ID authentication. If the RF tag that transmitted the data is an RF tag held by the user, 1 is output as the output value. In this case, the determination unit 11 determines that the second condition is satisfied, and proceeds to step E6. If the RF tag is not an RF tag possessed by the user, 0 is output as the output value. In this case, it is determined that the second condition is not satisfied, and the process returns to step E4.

  In step E6, the notification unit 8 generates a sound or vibration to notify the user that there is a missed call. Thereafter, the missed call notification flow is terminated.

  As described above, when an RFID tag that can communicate with a reader / writer receives radio waves from the reader / writer when the RFID is used, the RF tag transmits predetermined information for performing ID authentication to the reader / writer, and the reader / writer receives the information. ID authentication is performed using the predetermined information, and when this RF tag is an RF tag possessed by the user of the mobile phone terminal 100, it can be notified that there is a missed call.

  That is, notification is not performed even when a person other than the user approaches the mobile phone terminal 100, and it can be notified that there is a missed call only when the user approaches.

  Note that by setting an area in which the RF tag can receive radio waves from the reader / writer, it is possible to set to what extent the RF tag is to be notified of a missed call when approaching the reader / writer.

  In addition, it is not limited to a sensor that performs ID authentication with a terminal capable of communication such as an RFID tag such as RFID to detect that the user has approached the mobile phone terminal 100, and is connected to the mobile phone terminal wirelessly such as Bluetooth. When a user has a headset that is previously associated with a mobile phone terminal in a one-to-one relationship, and the headset is in an area where radio waves emitted from the mobile phone terminal can be received, as in the case of using RFID The user may be notified that there is a missed call.

  In addition, a contactless temperature sensor, an ultrasonic sensor, an infrared sensor, or the like is used as the contact detection sensor 10, and a contact is detected by transmitting a radio wave from the user to the contact detection sensor 10 in response to the radio wave from the contact detection sensor 10. You may make it detect that there exists a missed call by detecting that the user exists in the position where the electromagnetic wave from the sensor 10 reaches. In this case, it is possible to notify that there is a missed call if all moving objects, not only the user, are in a position where the radio waves from the contact detection sensor 10 can be received.

  Furthermore, the notification unit 8 is not limited to a unit that generates sound or vibration, and may be any unit that generates light using an LED or the like or notifies other users.

  Further, although the apparatus has been described in the present embodiment, a program for executing processing of the operation flow in the present embodiment is stored in the control unit 3 that controls each configuration of the mobile phone terminal, and the program is executed similarly. The effect of can be obtained.

  Hereinafter, a case where a program is used will be described. In FIG. 4, a case will be described in which a program is stored in the program storage unit 22 included in the control unit 3 and the same processing as in the present embodiment is performed by executing the program.

  A method for notifying the user that there is a missed call realized by the program will be described with reference to FIG. In step B1, the control unit 3 checks whether the missed call information 15 is stored in the storage unit 6. When not stored, the missed call notification flow is terminated, and when stored, the process proceeds to step B2.

  In step B2, the control unit 3 determines whether the detection value from the placement sensor 9 satisfies the first condition. If the detected value satisfies the first condition, the process proceeds to step B4. If the detected value does not satisfy the first condition, the missed call notification flow is terminated.

  In step B4, the control unit 3 determines whether the detection value from the touch sensor 10 satisfies the second condition. If the detected value is a detected value that satisfies the second condition, the process proceeds to step B6. If the detected value does not satisfy the second condition, the process returns to step B4.

  In step B6, the notification unit generates a sound or vibration to notify the user that there is a missed call. Thereafter, the missed call notification flow is terminated.

  Thus, the same effect as this embodiment can be obtained by storing the program for executing the processing of the operation flow in the present embodiment in the control unit 3 and executing the program.

  In addition, the control unit 3 that causes each of the above components to execute the same operation processing as described above is configured by the semiconductor integrated circuit 23, and the same effect as that of the present embodiment can be obtained even in a mobile phone terminal incorporating the semiconductor integrated circuit 23.

When not stored, the missed call notification flow is terminated, and when stored, the process proceeds to step B2.

  In step B2, the control unit 3 acquires the detection value from the placement sensor 9, outputs it to the determination unit 11, and causes the determination unit 11 to determine whether the detection value satisfies the first condition. When the control unit 3 receives an input indicating that the first condition is determined to be satisfied from the determination unit 11, the control unit 3 proceeds to step B4. When the control unit 3 receives an input indicating that the first condition is determined not to be satisfied from the determination unit 11, the control unit 3 ends the missed call notification flow.

  In step B4, the control unit 3 acquires the detection value from the touch sensor 10 and outputs it to the determination unit 11. In step B5, the determination unit 11 determines whether the detection value satisfies the second condition. If the control unit 3 receives an input indicating that the second condition is satisfied by the determination unit 11, the control unit 3 proceeds to step B6. When the determination unit 11 receives an input indicating that the second condition is not satisfied, the process returns to step B4.

  In step B <b> 6, the control unit 3 generates sound or vibration and causes the notification unit 8 to notify the user that there is a missed call. Thereafter, the missed call notification flow is terminated.

  In step B <b> 1, the determination unit 11 in the semiconductor integrated circuit 23 determines whether the missed call information 15 is stored in the storage unit 6. When it is determined that it is not stored, the missed call notification flow is terminated, and when it is determined that it is stored, the process proceeds to step B2.

  In step B <b> 2, the determination unit 11 acquires a detection value from the placement sensor 9 and determines whether the detection value satisfies the first condition. When it is determined that the first condition is satisfied, the process proceeds to step B4. When it is determined that the first condition is not satisfied, the missed call notification flow is terminated.

  In step B4, the determination unit 11 acquires the detection value from the touch sensor 10, and determines whether the detection value satisfies the second condition in step B5. When it is determined that the second condition is satisfied, the process proceeds to step B6. When it is determined that the second condition is not satisfied, the process returns to step B4.

  In step B6, the determination unit 11 causes the notification unit 8 to notify the user that there is a missed call. Thereafter, the missed call notification flow is terminated.

  As described above, the determination unit 11 for executing the operation processing in the present embodiment for each configuration of the mobile phone terminal 100 in the present embodiment is configured by the semiconductor integrated circuit 23, and the mobile phone terminal in which the semiconductor chip is incorporated. However, the same effect as this embodiment can be obtained.

However, the same effect as this embodiment can be obtained.

  Further, the user can change the notification method depending on the presence / absence of data such as an answering machine or a message memo, or notify only a specific missed call out of all missed call information 15 stored in the storage unit 6. The notification method and the notification target may be set in advance.

  As an example, a case will be described with reference to FIG. 4 where a setting is made to notify only a specific missed call in the missed call information 15 stored in the storage unit 6.

  The display unit 5 displays a setting screen shown in FIG. 17 by an operation from the user received by the input unit 4. The setting information for notifying the missed call received by how many hours ago input by the operation of the user (12 hours before in FIG. 17) or notifying only the missed call from the other party registered in the address book. And stored in the storage unit 6.

If the incoming date / time of the missed call information 15 stored in the storage unit 6 is an incoming call received 12 hours before the current time, it is determined that the setting information 19 is satisfied, and the process proceeds to step B2. Step B2 and subsequent steps are the same as in FIG. If the incoming call is received 12 hours ago, it is determined that the setting information 19 is not satisfied, and the missed call notification flow is terminated.

  As described above, by setting the missed call information 15 to be notified by the user in advance, the missed call information 15 applicable to the setting information 19 set by the user among the missed call information 15 stored in the storage unit 6 is stored. Notification can only be made if

  In the present embodiment, the incoming call is explained. However, in the case of an incoming mail, the operation flow for notifying that there is a missed incoming call when the user is touched is performed as described with reference to FIG. 9 or FIG. Thus, the same effect can be achieved.

(Embodiment 2)

  FIG. 19 is a block diagram showing a configuration of the mobile phone terminal 101 according to Embodiment 2 of the present invention. Since the mobile phone terminal according to the present embodiment does not need to detect contact with the user while the missed call information 15 is not stored in the storage unit 6, the missed call information 15 is stored in the storage unit 6. While not being used, power supply to the placing sensor 9 and the touch sensor 10 is eliminated to reduce power consumption.

  The mobile phone terminal 101 according to the embodiment of the present invention is configured by further including a switching unit 24 and a power source 25 in addition to the configuration of the mobile phone terminal according to the first embodiment. The description of the same configuration as that of the mobile phone terminal of Embodiment 1 is omitted.

  The power source 25 is a power source that supplies power to the placing sensor 9 and the contact detection sensor 10. The switching unit 24 is disposed so as to connect or disconnect the power supply 25 and the placement sensor 9 or the contact detection sensor 10. When the determination unit 11 determines that the missed call information 15 is not stored in the storage unit 6, the switching unit 24 disconnects the power supply 25 and the placement sensor 9 or the touch sensor 10. When the determination unit 11 determines that the missed call information 15 is stored in the storage unit 6, the switching unit 24 connects the power source 25 and the placement sensor 9 or the touch sensor 10.

  First, a method for storing the missed call information 15 when an incoming call is received will be described with reference to FIG. In FIG. 20, step A8 and step A10 are added to FIG. When the missed call information 15 is not in the storage unit 6, the switching unit 24 turns off the power supply 25 and the placement sensor 9 or the contact detection sensor 10.

When the missed call information 15 is present, the switching unit 24 sets the power supply 25 and the placement sensor 9 or the touch sensor 10 to the power supply state in step B8, and when the missed call information 15 is not present, the switching unit 24 is activated in step B7. The power source 25 and the placing sensor 9 or the power source 25 and the touch sensor 10 are turned off.

  In step B <b> 1, the determination unit 11 determines whether the missed call information 15 is stored in the storage unit 6. When it is determined that it is not stored, the process proceeds to step B7.

  In step B7, the switching unit 24 turns off the power supply 25 and the placement sensor 9 or the contact detection sensor 10, and when the power supply is already turned off, the switching unit 24 maintains the power off state and the missed call notification flow. Exit. When the determination unit 11 determines in step B1 that the missed call information 15 is stored in the storage unit 6, the process proceeds to step B8.

  In step B8, the switching unit 24 places the power supply 25 and the placement sensor 9 or the touch sensor 10 in the power connection state. If the switching unit 24 is already in the power connection state, the switching unit 24 maintains the power connection state and proceeds to step B2. . The description of the operation after step B2 is omitted.

  Furthermore, an operation flow when the user confirms the missed call information 15 will be described with reference to FIG. In FIG. 22, step C4 is added to FIG. When the user confirms the missed call, in step C4, the switching unit 24 turns off the power supply 25 and the placement sensor 9 or the touch sensor 10.

  In step C1, when the incoming call history is confirmed, the missed call information 15 is displayed on the display unit 5 (step C2), and the flag 16 indicating that the user included in the missed call information 15 is not responding is erased ( Step C3) goes to Step C4.

  In step C4, the switching unit 24 turns off the power supply 25 and the placement sensor 9 or the contact detection sensor 10. When it is already in the power-off state, the switching unit 24 maintains the power-off state. Thereafter, the missed call confirmation flow is terminated.

  As described above, in the mobile phone terminal 101 according to the present embodiment, the determination unit 11 determines whether the missed call information 15 is stored in the storage unit 6, and if the determination unit 11 determines that the missed call information 15 is stored, the switching unit 24 The power supply 25 and the placement sensor 9 or the contact detection sensor 10 are brought into a power supply connection state. When it is determined that the data is not stored, the switching unit 24 turns off the power supply 25 and the placement sensor 9 or the contact detection sensor 10.

  This makes it possible to stop the power supply to the placement sensor 9 and the contact detection sensor 10 while the missed call information 15 is not stored in the storage unit 6. Power consumption can be eliminated.
