  Hereinafter, preferred embodiments for carrying out the present invention will be described with reference to the drawings. First, a basic structure of a mobile phone 1 according to an embodiment of the mobile terminal device of the present invention will be described with reference to FIG. FIG. 1 is an external perspective view of a mobile phone 1 according to an embodiment of a mobile terminal device. FIG. 2 is a perspective view on the back surface 16 side of the operation unit side body 2 in the mobile phone 1.

The operation unit side body 2 includes an operation unit 11 and a microphone 12 on the front surface 10. The front surface 10 of the operation unit side body 2 is a surface facing the display unit side body 3 in a state in which the cellular phone 1 is folded.
The operation unit 11 includes function setting operation keys 13 for operating various functions such as various setting functions, dictionary functions, and mail functions, input operation keys 14 for inputting numbers and characters, and determination and scrolling in various operations. It is comprised from the determination operation key 15 which performs etc.
The microphone 12 is used for inputting a voice uttered by a user of the mobile phone 1 during a call.

The display unit side body 3 includes a display unit 31 and a receiver 32 on the front surface 30. The front surface 30 of the display unit side body 3 is a surface facing the operation unit side body 2 in a state where the cellular phone 1 is folded.
The display unit 31 displays various information (character information and image information) such as the telephone number and mail address of the other party of the call and the contents of the mail. The receiver 32 outputs the voice of the other party on the call.

  The hinge mechanism 4 connects the operation unit side body 2 and the display unit side body 3 so as to move relative to each other. The mobile phone 1 relatively rotates the operation unit side body 2 and the display unit side body 3 which are connected via the hinge mechanism 4, so that the operation unit side body 2 and the display unit side body 3 are rotated. Can be brought into an open state (open state), or the operation unit side body 2 and the display unit side body 3 can be folded (closed state).

  Although FIG. 1 shows a so-called foldable mobile phone 1, the mobile phone is not limited to this. In other words, a sliding type in which one casing is slid in one direction from a state in which the operation unit side casing and the display unit side casing are overlapped, or one casing centering on an axis along the overlapping direction. A rotary type in which the operation unit side body and the display unit side body are connected via a biaxial hinge, and the operation unit side body and the display unit side body are 1 It may be one (so-called straight type, flip type) arranged in one housing.

  Further, as shown in FIG. 2, a slide-type switch (such as a moving member 23 and a closing member 22) is provided on the back surface (surface opposite to the front surface 10) 16 of the operation unit side body 2. . As shown in FIG. 2A, when the switch is in an OFF state (the moving member 23 is closed), the user of the mobile phone moves the switch in the direction of arrow A shown in FIG. When the moving member 23 is open), the switch is turned on. The detailed configuration of the switch will be described later.

The mobile phone 1 configured as described above has a function of ensuring waterproofness while having a crime prevention function.
Below, the structure and operation | movement for exhibiting the said function which concerns on the mobile telephone 1 are explained in full detail.
FIG. 3 is a cross-sectional view for explaining a configuration of a portion where the moving member 23 is provided. FIG. 4 is a view for explaining the closing member 22. Here, FIG. 4A is a perspective view of the closing member 22. FIG. 4B is a cross-sectional view taken along the arrow in FIG. FIG. 5 is a cross-sectional view for explaining a case where the moving member 23 is in an open state.

  As shown in FIG. 3, the mobile phone 1 includes a control unit 20, a speaker 21 (output unit), an operation unit side housing 2 (housing unit), a closing member 22, and a moving member 23. Note that the switch includes the closing member 22, the moving member 23, and the like.

The speaker 21 outputs sound to the outside in accordance with control by the control unit 20. When a high signal is supplied to the control unit 20, the speaker 21 outputs an alarm sound, for example, according to control by the control unit 20. The speaker 21 outputs an alarm sound with a volume that can notify a third party other than the user that an emergency has occurred, or a volume that can intimidate a partner attacking the user. . On the other hand, when a low signal is supplied to the control unit 20, the speaker 21 does not output an alarm sound according to control by the control unit 20.
In the present embodiment, the speaker 21 is provided on the back surface 16 side of the operation unit side body 2. A plurality of holes 17 are provided in a portion facing the speaker 21 in the operation unit side body 2 (see FIG. 2). The hole 17 is closed by a material that allows air to pass but does not allow water to pass through, so that water does not enter.

The operation unit side body 2 houses the control unit 20 and has an opening 24 at a predetermined position.
The closing member 22 has an insulating property and closes the opening 24. In the case of this embodiment, the closing member 22 is fixed to the operation unit side body 2 so as to close the opening 24 from the inside of the operation unit side body 2. For this reason, a recess 25 is formed in the operation unit side body 2 by the side wall for forming the opening 24 and the closing member 22. As will be described later, the recess 25 restricts the movement of the protruding portion 231 formed on the moving member 23. For example, the concave portion 25 has a planar shape so that the moving direction of the protruding portion 231 is the left-right direction shown in FIG. May be formed in a rectangular shape.

  The blocking member 22 has two through holes formed in the insulating material 221 at a predetermined interval, and the first terminal 222 and the second terminal 223 are formed by filling the through holes with a conductive material. It is preferable (refer FIG. 4). Accordingly, the first member 222 and the second terminal 223 having conductivity are formed on the closing member 22 at a predetermined interval. Note that the first terminal 222 and the second terminal 223 are respectively exposed on the upper surface and the lower surface of the closing member 22.

  The closing member 22 can also be formed by, for example, a molding method. As a specific forming method, first, two conductive materials are arranged at a predetermined interval in a cavity in a mold for forming the closing member 22. The cavity is formed at the same height as the conductive material or slightly higher than the conductive material. The conductive material forms the first terminal 222 and the second terminal 223. Next, a resin to be the insulating material 221 is supplied to the cavity. After the resin molding is completed, the resin (blocking member 22) including a conductive material is taken out from the mold. When the upper surface or the lower surface of the conductive material is covered with a resin, the resin that covers the upper surface or the lower surface of the conductive material may be removed using a chemical or the like for removing the resin. In this way, the closing member 22 is formed.

  As shown in FIG. 3, the moving member 23 is provided in the opening 24 closed by the closing member 22 so as to be movable within a predetermined range, and is moved to be in a closed state (see FIG. 3) and an open state. (See FIG. 5). The moving member 23 includes a protruding portion 231 that protrudes from the base member 236 toward the opening 24 side. The protruding portion 231 is inserted into the concave portion 25 formed in the operation unit side body 2 and moves on the upper surface of the closing member 22. Furthermore, the movement direction and the movement range of the protruding portion 231 are limited by the side surface of the concave portion 25 (side wall of the operation unit side body 2 for forming the opening 24). Thereby, the moving member 23 becomes movable within a predetermined range.

  A third terminal 232, a fourth terminal 233, and a capacitor 234 (capacitance element) are electrically connected to each other at a predetermined interval on the surface of the moving member 23 that faces the opening 24. That is, the third terminal 232, the fourth terminal 233, and the capacitor 234 are electrically connected by the electrode pattern 235 drawn around the lower surface of the moving member 23 (base member 236). The third terminal 232 and the fourth terminal 233 are arranged along the direction in which the moving member 23 moves (the left-right direction in FIG. 3). When the moving member 23 is in the closed state (see FIG. 3), the third terminal 232 and the first terminal 222 are in contact with each other. Further, the fourth terminal 233 is in contact with the insulating material 221 between the first terminal 222 and the second terminal 223. That is, the fourth terminal 233 is not in contact with the first terminal 222 and the second terminal 223. On the other hand, when the moving member 23 transitions from the closed state to the open state (see FIG. 5), the third terminal 232 and the first terminal 222 are brought into a non-contact state, and the fourth terminal 233 and the first terminal The second terminal 223 comes into contact. In other words, the third terminal 232 contacts the insulating material 221 between the first terminal 222 and the second terminal 223.

  The operation unit side body 2 is connected to the power source 26 and connected to the control unit 20 and a voltage output terminal 27 that outputs a voltage supplied from the power source 26 to the first terminal 222. The signal detection terminal 28 for detecting the signal output from the second terminal 223 is formed.

Next, the operation of the mobile phone 1 when outputting sound from the speaker 21 will be described. FIG. 6 is a circuit diagram of the configuration shown in FIG.
First, when the moving member 23 is in a closed state (see FIG. 3), the capacitor 234 receives a voltage from the power source 26 via the voltage output terminal 27 when the third terminal 232 and the first terminal 222 are brought into contact with each other. Is supplied and charges are accumulated (see FIG. 6A). When the moving member 23 is in the closed state, the second terminal 223 is in a non-contact state with either the third terminal 232 or the fourth terminal 233, so that the control unit 20 receives a voltage (High signal). ) Is not supplied. Therefore, the control unit 20 does not output sound from the speaker 21.

  Next, in the capacitor 234, when the moving member 23 is changed from the closed state to the open state (see FIG. 5), the third terminal 232 and the first terminal 222 are brought into a non-contact state, and the fourth terminal 233 is reached. And the second terminal 223 are brought into contact with each other, so that a voltage based on the accumulated charge is output to the control unit 20 via the signal detection terminal 28. The control unit 20 causes the speaker 21 to output sound when a voltage is supplied from the signal detection terminal 28. That is, in the control unit 20, an interrupt factor is generated when a high signal is supplied from the signal detection terminal 28. The control unit 20 detects the release of the crime prevention switch from the interrupt factor, and performs control to output an alarm sound from the speaker 21.

  As described above, in the mobile phone 1, the opening 24 of the operation unit side body 2 is closed by the closing member 22 including the first terminal 222 and the second terminal 223, and an emergency situation has occurred in the user. In some cases, the moving member 23 is moved above the closing member 22, and the capacitor 234 is electrically connected to the second terminal 223. For this reason, the mobile phone 1 can prevent liquid from entering the inside of the operation unit side body 2 from the portion where the moving member 23 is provided. Furthermore, the mobile phone 1 can output a sound (for example, an alarm sound) from the speaker 21 when an emergency situation occurs in the user.

The moving member 23 may be provided with a strap 29. In this case, when the strap 29 is pulled in a predetermined direction, the moving member 23 moves and changes from the closed state to the open state. The strap 29 may have any shape as long as it can be pulled by the user. For example, the strap 29 may have an annular shape as shown in FIG. 2, and as shown in FIGS. The shape may include a string 29a attached to the moving member 23 and an annular portion 29b connected to the tip of the string 29a.
Therefore, since the mobile phone 1 causes the moving member 23 to transition to the open state when the strap 29 is pulled by the user, the moving member 23 can be quickly and surely opened even when an emergency occurs. Can do.

<Modification>
Next, a modified example of the portion where the moving member 23 is provided will be described. In addition, the component of the modification demonstrated below attaches | subjects the code | symbol same as the component of embodiment mentioned above to what has the same function as the component of embodiment mentioned above.

  First, modified examples of the moving member 23 (first modified example) and the closing member 22 (first modified example) will be described. FIG. 7 is a view for explaining a modified example of the moving member 23 and the closing member 22. Here, FIG. 7A is a bottom view of the moving member 23. FIG. 7B is a plan view of the closing member 22 (the opening 24 of the operation unit side body 2 provided with the closing member 22). FIG. 7C is a plan view of a portion where the moving member 23 is provided when the moving member 23 is in a closed state. FIG. 7D is a plan view of a portion where the moving member 23 is provided when the moving member 23 is in an open state.

As shown in FIG. 7A, the third terminal 232 and the fourth terminal 233 are arranged side by side along a direction that intersects the direction in which the moving member 23 moves (the left-right direction in the case shown in FIG. 7). The The third terminal 232 is arranged so as to be shifted from the fourth terminal 233 in the direction in which the moving member 23 transitions from the closed state to the open state (right direction in the case shown in FIG. 7). The third terminal 232 and the fourth terminal 233 are electrically connected to each other by an electrode pattern 235 provided on the bottom surface of the moving member 23. Note that the capacitor 234 (see FIG. 7A) is electrically connected to each of the third terminal 232 and the fourth terminal 233 by the electrode pattern 235.
As shown in FIG. 7B, the first terminal 222 and the second terminal 223 are arranged along a direction (vertical direction in the case shown in FIG. 7) orthogonal to the direction in which the moving member 23 moves. Be placed.

  As shown in FIG. 7C, when the moving member 23 is in the closed state, the first terminal 222 and the third terminal 232 are in contact with each other. Accordingly, the capacitor 234 is supplied with a voltage from the power source 26 (not shown in FIG. 7) via the first terminal 222 and the third terminal 232, and accumulates electric charges. On the other hand, the fourth terminal 233 is in contact with the insulating material 221 constituting the closing member 22. For this reason, the second terminal 223 is not in contact with any of the third terminal 232 and the fourth terminal 233.

  As shown in FIG. 7D, when the moving member 23 is in the open state, the first terminal 222 and the third terminal 232 are in a non-contact state. On the other hand, the second terminal 223 and the fourth terminal 233 are in a conductive state. As a result, the capacitor 234 supplies a voltage based on the accumulated charge to the control unit 20 (not shown in FIG. 7) via the second terminal 223 and the fourth terminal 233. As a result, the control unit 20 performs control to generate an interrupt factor based on the voltage (high signal) supplied from the capacitor 234 and output an alarm sound from the speaker 21 (not shown in FIG. 7). .

  Therefore, in the mobile phone 1, even when the third terminal 232 and the fourth terminal 233 are arranged along the direction intersecting the moving direction of the moving member 23, the moving member 23 is opened from the closed state. Since a high signal is supplied to the control unit 20 when the state is changed, a sound (for example, an alarm sound) can be output from the speaker 21.

Next, a second modification of the moving member 23 will be described. FIG. 8 is a diagram for explaining a second modification of the moving member 23. Here, FIG. 8A is a cross-sectional view illustrating a case where the moving member 23 is in a closed state and a bottom view of the moving member 23. FIG. 8B is a cross-sectional view illustrating the case where the moving member 23 is in the open state.
A third terminal 232 and a capacitor 234 are provided on the surface of the moving member 23 of the second modified example that faces the opening 24. The third terminal 232 and the capacitor 234 are electrically connected by the electrode pattern 235 drawn around the lower surface of the moving member 23.

When the moving member 23 is in the closed state (see FIG. 8A), the third terminal 232 and the first terminal 222 are in contact with each other, and the third terminal 232 and the second terminal 223 are not in contact with each other. It becomes a contact state. In this case, the capacitor 234 is supplied with voltage from the power supply 26 via the voltage output terminal 27, the first terminal 222, and the third terminal 232, and accumulates electric charges.
On the other hand, when the strap 29 connected to the moving member 23 is pulled by the user to open the moving member 23 (see FIG. 8B), the third terminal 232 and the second terminal 223 are used. And the third terminal 232 and the first terminal 222 are not in contact with each other. In this case, the capacitor 234 outputs a voltage based on the accumulated charge to the control unit 20 via the third terminal 232, the second terminal 223, and the signal detection terminal 28. The control unit 20 detects an interruption factor based on the supply of a voltage (high signal) from the capacitor 234 and performs control to output an alarm sound from the speaker 21.
Therefore, even if the mobile phone 1 is provided with only one terminal on the moving member 23, a high signal is sent to the control unit 20 when the moving member 23 is changed from the closed state to the open state. Therefore, a sound (for example, an alarm sound) can be output from the speaker 21.

  Next, a third modification of the moving member 23 will be described. FIG. 9 is a diagram for explaining a third modification of the moving member 23. Here, FIG. 9A is a cross-sectional view showing a case where the moving member 23 is in a closed state and a bottom view of the moving member 23. FIG. 9B is a cross-sectional view showing a case where the moving member 23 is in an open state.

  A third terminal 232 and a fourth terminal 233 are provided on the surface of the moving member 23 according to the third modification facing the opening 24. The third terminal 232 and the fourth terminal 233 are arranged side by side along the moving direction of the moving member 23 (the left-right direction in the case shown in FIG. 9). The third terminal 232 and the fourth terminal 233 are electrically connected by the electrode pattern 235 routed around the lower surface of the moving member 23.

  When the moving member 23 is in the closed state (see FIG. 9A), the fourth terminal 233 and the first terminal 222 are in contact with each other. The third terminal 232 is in contact with the insulating material 221 (the closing member 22) on the side opposite to the second terminal 223. In this case, no voltage is supplied from the power source 26.

  On the other hand, when the strap 29 connected to the moving member 23 is pulled by the user to open the moving member 23 (see FIG. 9B), the third terminal 232 and the first terminal 222 are used. And the fourth terminal 233 and the second terminal 223 are in contact with each other. In this case, the power supply 26 is connected to the voltage output terminal 27, the first terminal 222, the third terminal 232, the fourth terminal 233, the second terminal 223, and the signal detection terminal 28. A voltage (High signal) is supplied to the control unit 20. The control unit 20 detects an interrupt factor based on the supply of a voltage (high signal) from the power supply 26 and performs control to output an alarm sound from the speaker 21.

  Therefore, even when the mobile terminal 1 is provided with the third terminal 232 and the fourth terminal 233 on the moving member 23, the mobile phone 1 is controlled by the transition of the moving member 23 from the closed state to the open state. Since a high signal is supplied to 20, a sound (for example, an alarm sound) can be output from the speaker 21.

  Next, a second modification of the closing member 22 will be described. FIG. 10 is a diagram for explaining a second modification of the closing member 22. Here, FIG. 10A is a perspective view of the closing member 22. FIG. 10B is a cross-sectional view taken along the arrow in FIG.

  The closing member 22 of the second modified example includes an insulating material 221 serving as a base, and a first terminal 222 and a second terminal 223 provided on the surface of the insulating material 221, respectively. The first terminal 222 includes an electrode pattern in which the upper surface 221a, the left side surface 221b, and the lower surface 221c of the insulating material 221 are routed. The second terminal 223 is configured by an electrode pattern in which the upper surface 221a, the right side surface 221d, and the lower surface 221c of the insulating material 221 are routed.

  Such first terminal 222 and second terminal 223 may be formed as follows, for example. That is, the insulating material 221 is covered with a mask in which openings are formed corresponding to portions where the first terminals 222 and the second terminals 223 are formed. After that, the insulating material 221 covered with the mask is put into a film forming apparatus such as a vacuum evaporation apparatus, an ion plating apparatus, or a sputtering apparatus. Next, a thin film made of a metal material such as gold (Au) is formed on the insulating material 221 exposed from the opening of the mask by a film forming apparatus. Thereafter, the insulating material 221 is taken out from the film formation apparatus, and the mask is removed from the insulating material 221, whereby the insulating material 221 (the closing member 22) in which the first terminal 222 and the second terminal 223 are formed is obtained.

  Note that in FIG. 10B, the first terminal 222 and the second terminal 223 are illustrated as being thicker than actual in order to make the first terminal 222 and the second terminal 223 easier to understand. For this reason, even when the electrode-patterned first terminal 222 and the second terminal 223 are formed in the insulating material 221, the third terminal 232 or the fourth terminal 233 associated with the movement of the moving member 23 is used. The movement is not hindered by the first terminal 222 or the second terminal 223.

  Similar to the embodiment described above, such a closing member 22 is fixed to the operation unit side body 2 so as to close the opening 24 of the operation unit side body 2. In this case, even when a slight step is present on the surface of the insulating material 221 due to the first terminal 222 and the second terminal 223, a sealing member (for example, between the operation unit side body 2 and the closing member 22 is used. By disposing the insulating adhesive), it is possible to prevent moisture from entering from a slight gap generated between the closing member 22 and the operation unit side body 2 based on the level difference of the surface of the insulating material 221.

  Therefore, the cellular phone 1 has the operation unit side housing even when the closing member 22 formed by the first terminal 222 and the second terminal 223 being drawn around the surface of the insulating material 221 is used. Since the second opening 24 is closed, it is possible to prevent liquid from entering the inside of the operation unit side body 2 from the portion where the moving member 23 is provided.

  In the embodiment and the modification described above, the case where the tips of the third terminal 232 and the fourth terminal 233 have a sharp shape has been described. However, the present invention is not limited to this form, and each of the third terminal 232 and the fourth terminal 233 may have another shape. As an example, the third terminal 232 and the fourth terminal 233 may have a rounded tip as shown in FIG. 11A, or a semi-cylinder as shown in FIG. It may be a shape. Note that in the case where the third terminal 232 and the fourth terminal 233 have a semicircular shape illustrated in FIG. 11B, the third terminal 232 and the fourth terminal 233 are in the direction of arrow B (left-right direction) illustrated in FIG. ), The friction generated with the closing member 22 is reduced.

  In the embodiment and the modification described above, the case where the moving member 23 and the closing member 22 are provided in the operation unit side body 2 has been described. However, the present invention is not limited to this form, and the moving member 23 and the closing member 22 may be provided in the display unit side body 3.

  Further, in the above-described embodiments and modifications, the case where the mobile terminal device of the present invention is applied to the mobile phone 1 has been described as an example. However, the present invention is not limited to this embodiment, and can also be applied to portable terminal devices such as PHS (Personal Handyphone System), PDA (Personal Digital Assistant), and security devices.
