Description

  The present invention relates to a holding device, a portable terminal, a processing system, and an information processing method.

  In order to reduce power consumption, a function called an automatic sleep mode is provided in most portable terminals. The automatic sleep mode is a mode that automatically shifts to a state in which the screen of the mobile terminal is turned off if the mobile terminal is not accessed for a certain period of time. The access to the mobile terminal means an input by an active operation performed by the user with respect to the mobile terminal.

  The active operation performed by the user with respect to the mobile terminal corresponds to, for example, an instruction input operation when the user presses a button provided on the mobile terminal. On the other hand, a passive operation performed on the mobile terminal by the user, for example, an operation of the user viewing the screen of the mobile terminal is not included in the “access”. Therefore, when the automatic sleep mode is set on the mobile terminal, even if the user tries to look at the screen of the mobile terminal for a long time, when the predetermined time elapses, the user automatically enters the sleep mode that turns off the screen. Resulting in. If the user shifts to the sleep mode while watching a moving image or the like, the screen becomes dark during the reproduction of the moving image. Therefore, even if the user looks at the screen, the transition to the sleep mode contributes to the user's dissatisfaction with the automatic sleep mode.

  As a method for solving this problem, a touch sensor is provided on the side surface of the casing of the mobile terminal, and it is determined whether or not the user is looking at the screen based on whether or not the touch sensor detects contact with the user's finger. A method is disclosed in Patent Document 1.

  Further, Patent Document 2 discloses a method for providing a tension detection means for detecting the tension of a strap for suspending the camera body to determine whether or not the user is using the camera. When the camera body is hung from the strap and the tension is detected by the tension detection means, the camera control means determines that the body is being carried and performs control to shift to a power saving mode for stopping a specific function. However, when the user takes a picture with the strap pulled, if the camera body is hung on the strap, the tension detection means may erroneously detect and the control means may turn off the camera. was there. Therefore, in the method disclosed in Patent Document 2, an acceleration sensor is provided in the camera as a detection assisting unit in addition to the tension detecting unit, and the acceleration sensor detects shaking and tilt of the camera body, and based on the detection result, the user Whether or not is using a camera is determined.

  When the touch sensor is provided on the side surface of the casing of the mobile terminal, the way to hold the mobile terminal varies depending on the user, so when the user grabs a part other than the touch sensor and looks at the screen, the mobile terminal grips the terminal. If not, it will be misjudged.

  When an acceleration sensor is provided on a mobile terminal to detect whether the user is looking at the screen of the mobile terminal by detecting the tilt or shaking of the mobile terminal, the attitude of the user when viewing the screen Therefore, it is difficult to set a detection range for determining that the user is looking at the screen. For this reason, even if the user looks at the screen, it may happen that the user does not look at the screen. This problem is not limited to the case where the user looks at the screen, and all passive operations on the mobile terminal are targeted.

FIG. 1 is a block diagram showing a configuration example of an information processing system according to an embodiment of the present invention. FIG. 2 is a block diagram showing a configuration example of the holding device shown in FIG.

  As illustrated in FIG. 1, the information processing system includes a mobile terminal 10 and a holding device 20 that holds the mobile terminal 10.

  As shown in FIG. 2, the holding device 20 detects a holding unit 21 that holds the mobile terminal 10, a prevention unit 22 that prevents the mobile terminal 10 from falling, and whether the prevention unit 22 is in a fall-preventing state.

Twelve. The mobile terminal 10 is physically connected via the holding device 20 and the holding means 21, and the receiving means 11 and the connecting means 24 are electrically connected.

  Since the mobile terminal 10 transmits a detection result indicating whether or not the terminal itself is in the fall prevention state from the holding device 20, the mobile terminal 10 determines that the user is using the mobile terminal 10 if in the fall prevention state, The predetermined function can be restricted or the restriction can be released according to the user's use.

  The mobile terminal of the present invention is not limited to a mobile phone / smartphone, but other mobile devices such as a game machine, a portable music player, a digital camera, a tablet PC (Personal Computer), a notebook PC, and a PDA (Personal Data Assistants: Portable information terminal). Hereinafter, embodiments of the holding device, the portable terminal, and the processing system of the present invention will be described in detail.

(First embodiment)
The configuration of the processing system of this embodiment will be described. FIG. 3 is a block diagram showing a configuration example of the processing system according to the present embodiment.

  As illustrated in FIG. 3, the processing system includes a holding device 200 and a mobile terminal 100. In the present embodiment, the case where the mobile terminal 100 is a mobile phone will be described. However, the configuration and operation related to the present invention will be described in detail, and detailed description of the configuration and operation related to general functions as a mobile phone will be omitted. To do.

  The configurations of the holding device 200 and the mobile terminal 100 according to the present embodiment will be described.

  FIG. 4 is an external view for explaining the configuration of the processing system of the present embodiment.

  The portable terminal 100 has a display unit 101. In the present embodiment, the display unit 101 is a control target for reducing power consumption, but the control target is not limited to the display unit 101. The display unit 101 includes a backlight (not shown) for turning on the screen and a touch panel (not shown) for the user to input instructions.

  The holding device 200 shown in FIG. 3 has a ring strap 210. A ring strap is a strap to which a ring is attached. The ring strap 210 includes a strap unit 202 that serves as a holding unit for holding the mobile terminal 100, a ring 201 that serves as a prevention unit that prevents the mobile terminal 100 from falling when combined with the strap unit 202, and a signal Line 203.

  The mobile terminal 100 and the ring 201 are physically connected via a strap unit 202 and electrically connected via a signal line 203. FIG. 4 shows a state in which the ring strap 210 is connected to the mobile terminal 100.

  When using the mobile terminal 100, the user passes his / her finger 300 through the ring 201 in the direction of the arrow shown in FIG. By doing in this way, even if the user accidentally removes the mobile terminal 100 from the hand, the ring 201 is attached to the finger 300, so that the mobile terminal 100 hangs on the finger 300 via the ring 201 and the strap portion 202. The mobile terminal 100 can be prevented from falling on the ground.

  Various members can be considered as members used for the ring 201. As an example, an insulator that easily expands and contracts, for example, an elastic body such as rubber may be used for the member of the ring 201. In this case, since the inner diameter of the ring 201 becomes flexible, if the user passes the ring 201 through a finger thicker than the inner diameter of the ring 201, the adhesion between the ring 201 and the finger increases, and the fall prevention effect is enhanced. By making the inner diameter of the ring 201 flexible, the user can widen the selection range of the finger passing through the ring 201.

  For example, when the user uses the mobile terminal 100 while standing on a train, the user may pass the ring 201 with a finger thicker than usual. This is because if the mobile terminal 100 is dropped while the user is standing, the fall distance will be larger than if the mobile terminal 100 is dropped on the desk while sitting, and the mobile terminal 100 may be damaged. This is because even if the finger is slightly tightened in 201, it is better to further improve the fall prevention effect.

  FIG. 5 is an external perspective view showing a structural example of the ring shown in FIG.

  As shown in FIG. 5, the sensor unit 204 is mounted on a part of the circumference of the ring 201. The sensor unit 204 detects a change in capacitance due to the influence of the finger 300. The strap unit 202 and the signal line 203 shown in FIG. 4 are connected to the sensor unit 204 in the direction of the arrow shown in FIG. 5, but these configurations are not shown in FIG.

  FIG. 6 is a diagram for explaining the configuration of the sensor unit shown in FIG. 6 is a cross-sectional perspective view showing the structure of the ring 201 shown in FIG. 5 when the portion including the sensor portion 204 is cut in the direction of the arrow along the one-dot chain line shown in FIG.

  The sensor unit 204 includes a capacitance sensor including a sensor pad 205 and a ground plate 207 made of a conductor, an insulating plate 208a that supports the sensor pad 205, and protective resins 206a and 206b made of an insulator. . The capacitance sensor functions as the detection means 23 shown in FIG. The protective resin 206a is provided on the inner surface of the ring 201 shown in FIG. FIG. 6 shows a case where the material of the protective resin 206a is transparent, but it need not be transparent.

  The protective resin 206b is provided on the outer side of the ring 201 shown in FIG. 5 with respect to the protective resin 206a, and the sensor pad 205, the ground plate 207, and the insulating plate 208a are disposed between the protective resin 206a and the protective resin 206b. . A gap 230 is provided between the ground plate 207 and the sensor pad 205. The sensor pad 205 and the ground plate 207 are electrically connected to the portable terminal 100 via the signal line 203.

  The signal line 203 is configured so that the insulator 208b, the ground line 211, and the protective coating 212 cover the conductor 209 concentrically from the inside to the outside with the conductor 209 as the central axis. The conductive wire 209 is electrically connected to the sensor pad 205, and the ground wire 211 is electrically connected to the ground plate 207. The insulating plate 208a is physically connected to the insulator 208b. The sensor pad 205 is electrically connected to the mobile terminal 100 via a conductive wire 209, and the ground plate 207 is electrically connected to the mobile terminal 100 via a ground wire 211.

  FIG. 7 is a diagram for explaining the operation of the sensor unit shown in FIG.

  In a state where the user's finger 300 is not in the ring 201, there is a parasitic capacitance 214 (shown by a solid line) between the sensor pad 205 and the ground plate 207. When the finger 300 enters the ring 201, a capacitance 215 (shown by a broken line) is generated between the finger 300 (a conductor grounded to the ground) and the sensor pad 205 (conductor), and the sensor pad 205 and the ground plate The capacity between 207 increases. The measured change in capacity is transmitted to the portable terminal 100 via the signal line 203.

  When the user uses the portable terminal 100, his / her finger is put into the ring 201 and used for any purpose of active use and passive use. Therefore, the ring strap 210 not only prevents the mobile terminal 100 from falling, but is at least passively used with respect to the mobile terminal 100 even if the user does not actively input to the mobile terminal 100. This also serves to notify the mobile terminal 100 of this fact.

  FIG. 8 is an external view for explaining a connection configuration between the portable terminal and the holding device shown in FIG. FIG. 8 shows a state in which the strap portion 202 of the ring strap 210 is passed through the strap hole 102 of the mobile terminal 100.

  After passing the strap portion 202 of the ring strap 210 through the strap hole 102 of the mobile terminal 100, the ring strap 210 is fixed to the mobile terminal 100 by pulling the ring 201 through the loop of the strap 202 portion. The connector 103 on the mobile terminal 100 side and the connector 213 on the ring strap 210 side are connection terminals for electrically connecting the signal line 203 and the mobile terminal 100.

  FIG. 9 is a block diagram illustrating a configuration example of the holding device and the mobile terminal illustrated in FIG.

  The holding device 200 includes the ring strap 210 described with reference to FIGS. 4 to 8 and the connector 213. The ring strap 210 is electrically connected to the connector 103 on the portable terminal 100 side via the connector 213. The signal line 203 and the connector 213 serve as connection means for transmitting the capacitance generated between the sensor pad 205 and the ground plate 207 to the portable terminal 100 as a detection result by the capacitance sensor.

  As illustrated in FIG. 9, the mobile terminal 100 includes a display unit 101, a control unit 106, an oscillation circuit 104, and an oscillation state detection circuit 105. In the present embodiment, the oscillation circuit 104 and the oscillation state detection circuit 105 serve as a reception unit that receives the detection result from the capacitance sensor from the holding device 200. The control unit 106 includes a CPU (Central Processing Unit) (not shown) that executes processing according to a program, and a memory (not shown) that stores the program.

  When activated by an instruction from the control unit 106, the oscillation circuit 104 oscillates at a frequency corresponding to the capacity indicated by the detection result transmitted from the holding device 200. For example, the oscillation frequency of the oscillation circuit 104 decreases as the capacitance value transmitted from the holding device 200 increases, and the oscillation frequency increases as the capacitance value transmitted from the holding device 200 decreases. The oscillation state detection circuit 105 measures a change in the oscillation frequency of the oscillation circuit 104 and transmits the measured change in the frequency to the control unit 106.

  It is assumed that an automatic sleep mode is set in advance in the control unit 106 by a user operation. With this setting, the control unit 106 stops power supply to the backlight of the display unit 101 and turns off the screen if the mobile terminal 100 is not accessed for a certain period of time. Hereinafter, the setting for turning off the screen if the mobile terminal 100 is not accessed for a certain period of time is referred to as “sleep mode ON”, and the setting for not turning off the screen even if there is no access for a certain period of time is referred to as “sleep mode OFF”. In the present embodiment, the predetermined function to be controlled is set to the automatic sleep mode.

  After the mobile terminal 100 is activated, the control unit 106 instructs the oscillation circuit 104 to start oscillation, and monitors a signal indicating a change in frequency transmitted from the oscillation state detection circuit 105. When the control unit 106 determines that the measurement capacity of the capacitance sensor has increased from the signal indicating the change in frequency, the control unit 106 recognizes that the user is looking at the screen, and when the sleep mode ON is set, the sleep mode ON The function is restricted and the setting is switched to the sleep mode OFF.

  When the control unit 106 determines that the measured capacitance of the capacitance sensor has decreased from the signal indicating the change in frequency transmitted from the oscillation state detection circuit 105, the control unit 106 recognizes that the user is not looking at the screen and sleeps. If the sleep mode OFF is set due to a restriction on the mode ON function, the restriction is released and the setting is switched to the sleep mode ON.

  Next, the operation of the mobile terminal 100 of this embodiment will be described. FIG. 10 is a flowchart showing an operation procedure of the mobile terminal in the present embodiment. Assume that the automatic sleep mode is set in advance in the mobile terminal 100.

  The portable terminal 100 monitors the detection result by the sensor unit 204 transmitted from the ring strap 210 (step S001). When the user inserts the finger 300 into the ring 201, a capacitance of 215 capacitance is generated between the sensor pad 205 and the ground plate 207. As a result, the capacitance sensor of the sensor unit 204 detects an increase in measurement capacitance, and the detection result is transmitted from the ring strap 210 to the portable terminal 100. When the finger 300 is not in the ring 201 of the ring strap 210, the capacitance measured by the capacitance sensor of the sensor unit 204 remains the parasitic capacitance 214, so the portable terminal 100 returns to the monitoring state.

  When the portable terminal 100 determines in step S001 that the measurement capacity of the capacitance sensor has increased from the detection result transmitted from the ring strap 210, the portable terminal 100 recognizes that the user is putting the finger 300 on the ring 201 and watching the screen. To do. Subsequently, the mobile terminal 100 determines whether or not the screen is turned off (step S002). If the result of determination is that the screen is off, the screen is switched on (step S003).

  After turning on the screen, the mobile terminal 100 confirms the setting state of the automatic sleep mode (step S004). If the sleep mode is set to OFF, the portable terminal 100 maintains the setting, and if the sleep mode is set to ON, the setting of the automatic sleep mode is forcibly switched from ON to OFF (step S005).

  Thereafter, the mobile terminal 100 monitors whether or not the capacity indicated by the detection result by the sensor unit 204 transmitted from the ring strap 210 decreases (step S006). When the user pulls out the finger 300 from the ring 201, the capacitance 215 generated between the sensor pad 205 and the ground plate 207 disappears. Thereby, the sensor unit 204 detects a decrease in the measurement capacity, and a signal corresponding to the decrease in the measurement capacity is transmitted from the ring strap 210 to the portable terminal 100.

  In step S006, the portable terminal 100 determines that the measurement capacity of the capacitance sensor has decreased from the detection result transmitted from the ring strap 210, and recognizes that the user has stopped looking at the screen and has pulled out the finger 300 from the ring 201. . And the portable terminal 100 confirms the setting state of automatic sleep mode (step S007). If the sleep mode is forcibly set to OFF, the mobile terminal 100 cancels the setting (step S008) and validates the user setting. Thereby, the setting of the automatic sleep mode is switched from the sleep mode OFF to the sleep mode ON.

  In the present embodiment, the user prevents the mobile terminal from dropping by passing the finger through the ring of the ring strap, and the electrostatic capacitance sensor provided inside the ring detects that the user has passed the finger through the ring. The detection result is transmitted to the mobile terminal. For this reason, the mobile terminal determines that the user is looking at the screen of the mobile terminal, and maintains power supply to the backlight without turning off the screen even if the automatic sleep mode is set in advance. For example, even if the user slowly watches the Web page displayed on the screen over time, the screen does not suddenly become dark. Further, when the user removes his / her finger from the ring, the automatic sleep mode is returned to the original setting state, so that the effect of reducing power consumption can be made effective.

  According to the present embodiment, the holding device detects that the mobile terminal is in a fall-prevented state, so that it is used not only when the user is looking at the screen but also in a passive operation with respect to the mobile terminal. However, the mobile terminal can be operated as being used by the user.

  In the present embodiment, a case has been described in which one ring capacitance sensor for measuring capacitance is provided in the ring 201, but a plurality of capacitance sensors may be provided.

(Second Embodiment)
In the present embodiment, a mechanical switch is used instead of the capacitance sensor as the detection means shown in FIG. In the present embodiment, the case where the mechanical switch is a membrane switch will be described. In this embodiment, the case where the control target is the automatic sleep mode will be described.

  The processing system of the present embodiment has a configuration including the mobile terminal 100 and the holding device 200, similarly to the configuration shown in FIG. In this embodiment, a detailed description of the same configuration as that of the first embodiment is omitted, and a configuration and operation different from those of the first embodiment will be described in detail.

  FIG. 11 is an external view for explaining a connection configuration between the portable terminal and the holding device in the present embodiment.

  The ring strap 250 includes a strap portion 202, a ring 201, and a signal line 404. In the present embodiment, as shown in FIG. 11, a rubber-like membrane switch 402 is provided in the ring 201. The membrane switch 402 is switched from an OFF state to an ON state by being pushed by the finger 300 when the user puts the finger 300 into the ring 201, and is switched from an ON state to an OFF state when the user pulls the finger 300 out of the ring 201. In this way, the membrane switch 402 detects whether or not the user has put the finger 300 in the ring 201.

  The mobile terminal 100 and the ring 201 are physically connected via a strap unit 202 and electrically connected via a signal line 404. The connector 110 on the mobile terminal 100 side and the connector 405 on the ring strap 250 side are connection terminals for electrically connecting the signal line 404 and the mobile terminal 100.

  FIG. 12 is a block diagram illustrating a configuration example of the holding device and the mobile terminal in the present embodiment.

  The holding device 200 includes the ring strap 250 and the connector 405 shown in FIG. The ring strap 250 is electrically connected to the portable terminal 100 via the signal line 404 and the connector 405. The signal line 404 and the connector 405 serve as connection means for transmitting a signal indicating an ON state or an OFF state to the portable terminal 100 as a detection result of the membrane switch 402.

  The signal line 404 has a conducting wire 409 and a conducting wire 411. The conducting wire 409 has one end connected to one electrode of the membrane switch 402 and the other end connected to the connector 405. The conducting wire 411 has one end connected to the other electrode of the membrane switch 402 and the other end connected to the connector 405. In the configuration of the signal line 404, for example, in the signal line 203 illustrated in FIG. 6, the conductive line 209 corresponds to the conductive line 209, and the conductive line 411 corresponds to the ground line 211.

  The mobile terminal 100 according to the present embodiment includes a display unit 101, a control unit 106, a pull-up resistor 111 and a pull-down resistor 112, and a connector 110. In this embodiment, the pull-up resistor 111 and the pull-down resistor 112 serve as receiving means for receiving the detection result of the membrane switch 402 from the holding device 200 indicating whether or not the own terminal is in the fall prevention state.

  The pull-up resistor 111 has one of two terminals connected to a voltage line to which the internal voltage Vcc is supplied and the other terminal connected to the signal line 121. The pull-down resistor 112 is connected between the ground line to which the ground potential is applied and the signal line 122. When the resistance value of the pull-up resistor 111 is R1 and the resistance value of the pull-down resistor 112 is R2, the relationship between these two resistance values is R1 << R2.

  The signal line 121 is connected to a conducting wire 409 on the ring strap 250 side via connectors 110 and 405. The signal line 122 is connected to the conductor 411 on the ring strap 250 side via the connectors 110 and 405. The signal line 122 is connected to the control unit 106.

  When the user inserts the finger 300 into the ring 201 of the ring strap 250, the state of the membrane switch 402 changes from OFF to ON by pressing the finger 300, and the potential level of the signal line 122 changes from LOW to HIGH due to the relationship of R1 << R2. Change. When the user pulls out the finger 300 from the ring 401, the state of the membrane switch 402 changes from ON to OFF because the finger 300 is released from being pressed, and the pull-down resistor 112 having a resistance value R2 that is much larger than the resistance value R1. The potential level of the signal line 122 changes from HIGH to LOW.

  It is assumed that an automatic sleep mode is set in advance in the control unit 106 by a user operation. The control unit 106 monitors the potential level of the signal line 122 after the mobile terminal 100 is activated. When the potential level of the signal line 122 changes from LOW to HIGH, the control unit 106 determines that the membrane switch 402 is turned on, recognizes that the user is looking at the screen, and sets the sleep mode ON. The sleep mode ON function is limited, and the setting is switched to the sleep mode OFF.

  Further, when the potential level of the signal line 122 changes from HIGH to LOW, the control unit 106 determines that the membrane switch 402 is turned OFF, recognizes that the user is not looking at the screen, and restricts the sleep mode ON function. If the sleep mode OFF is set by, the restriction is canceled and the setting is switched to the sleep mode ON.

  Next, the operation of the mobile terminal 100 of this embodiment will be described. FIG. 13 is a flowchart showing an operation procedure of the mobile terminal in the present embodiment. Assume that the automatic sleep mode is set in advance in the mobile terminal 100.

  The portable terminal 100 monitors the state of the membrane switch 402 by referring to the potential level transmitted from the ring strap 250 via the signal line 122 (step S101). When the user inserts the finger 300 into the ring 201, the state of the membrane switch 402 is switched from OFF to ON by pressing the finger 300. As a result, the potential level of the signal line 122 changes from LOW to HIGH.

  If the portable terminal 100 determines in step S101 that the membrane switch 402 has been turned on due to a change in the potential level of the signal line 122, the portable terminal 100 recognizes that the user is looking at the screen with the finger 300 in the ring 201. Subsequently, the mobile terminal 100 determines whether or not the screen is turned off (step S102). If the result of determination is that the screen is off, the screen is switched on (step S103).

  After turning on the screen, the mobile terminal 100 checks the setting state of the automatic sleep mode (step S104). If the sleep mode is set to OFF, the mobile terminal 100 maintains the setting, and if the sleep mode is set to ON, the setting of the automatic sleep mode is forcibly switched from ON to OFF (step S105).

  Thereafter, the portable terminal 100 monitors the state of the membrane switch 402 by referring to the potential level transmitted from the ring strap 250 via the signal line 122 (step S106). When the user pulls out the finger 300 from the ring 201, the state of the membrane switch 402 is switched from ON to OFF because the finger 300 is released from being pressed. As a result, the potential level of the signal line 122 changes from HIGH to LOW.

  If the portable terminal 100 determines in step S106 that the membrane switch 402 has been turned off due to a change in the potential level of the signal line 122, the portable terminal 100 recognizes that the user has stopped looking at the screen and has pulled the finger 300 out of the ring 201. And the portable terminal 100 confirms the setting state of automatic sleep mode (step S107). When the sleep mode is forcibly set to OFF, the mobile terminal 100 cancels the setting (step S108) and validates the user setting. Thereby, the setting of the automatic sleep mode is switched from the sleep mode OFF to the sleep mode ON.

  In this embodiment, the user prevents the mobile terminal from falling by passing a finger through the ring of the ring strap, and the switch provided inside the ring detects that the user has passed the finger through the ring, and the detection The result is transmitted to the mobile terminal. Therefore, the same effect as that of the first embodiment can be obtained. In the present embodiment, the circuit configuration of the receiving unit 11 in the mobile terminal 10 can be simplified as compared with the first embodiment.

  In the first and second embodiments described above, the prevention means 22 shown in FIG. 2 is described as a ring, but the shape of the prevention means 22 is not limited to the ring.

  FIG. 14A shows a case where the prevention means 22 has a notch ring 231 in which a notch is provided in a part of the ring 201. A sensor unit 204 is provided on a part of the circumference of the notch ring 231. As shown in FIG. 14A, even if the ring 201 has a shape that is 10 to 15% of the entire circumference, the user can prevent the mobile terminal 100 from falling by passing the finger through the notched ring 231. The effect of can be obtained.

  FIG. 14B shows a case where a finger suck 232 is used as the prevention means 22 instead of the ring 201. The sensor unit 204 is disposed inside the finger sack 232. If the member of the finger sack 232 is made of an elastic body such as rubber, the elastic body is more likely to be in close contact with the user's finger and the fall prevention effect is enhanced.

  FIG. 14 (c) shows a configuration in which a fastener 235 for changing the size of the loop is provided on the strap 234 serving as the holding means 21 as the prevention means 22. In the configuration shown in FIG. 14C, the strap 234 incorporates the signal line 203 shown in FIG. A sensor unit 204 is provided on the fastener 235. When using the mobile terminal 100, the user widens the loop of the strap 234 and passes it to his / her wrist, and then tightens the fastener 235 so that the size of the loop becomes the thickness of the wrist. Thereby, the sensor part 204 comes to contact a user's wrist. Even when the user accidentally removes the mobile terminal 100 from the hand and the strap 234 is pulled in the direction of the ground due to gravity applied to the mobile terminal 100, the fastener 235 prevents the strap 234 from slipping from the wrist, and the ground of the mobile terminal 100 Prevents falling to the.

  In addition, the position of the sensor part 204 shown to Fig.14 (a)-FIG.14 (c) is not limited to the position shown in each figure. Also in the configuration shown in FIGS. 14A to 14C, a mechanical switch may be provided as a detection means instead of the capacitance sensor.
