As shown in FIG. 9, when the first case 1 and the second case 2 are overlapped and closed, the first sensor 13 is placed in the first case 1 where the first magnet 11 corresponds. It is provided so that the first magnet 11 reacts to the lines of magnetic force when it approaches and responds.

As shown in FIG. 8B, the second sensor 14 is composed of a magnetoresistive element (MR element: Magneto Resistance element) that reacts to magnetic lines of force parallel to the detection surface 14a.

That is, as shown in FIG. 9, the second sensor 14 reacts to the magnetic lines of force of the second magnet 12 when the first case 1 and the second case 2 are closed and overlapped, as shown in FIG. As shown, when the first case 1 and the second case 2 are rotated about the first rotation shafts 4 and 5 of the hinge portion 3 and opened at an angle of 90 °, the first magnet 11 is moved to the second case. The magnetic force line of the first magnet 11 rotates 90 ° and the direction of the magnetic force line changes by rotating and moving together with the auxiliary case 3a of the second auxiliary case 3a. Also configured to react.

Next, the operation of this mobile phone will be described.
First, as shown in FIG. 2A, the first case 1 and the second case 2 are supported with the key input unit 1a of the first case 1 and the display unit 2a of the second case 2 facing each other. When overlapped and folded together with the case 3a, the first magnet 11 corresponds to the first sensor 13 and the second magnet 12 corresponds to the second sensor 14, as shown in FIG.

At this time, since the first magnet 11 approaches the first sensor 13 and responds, the lines of magnetic force of the first magnet 11 become perpendicular to the detection surface 13a of the first sensor 13, so the first sensor 13 is turned on in response to the magnetic field lines of the first magnet 11 (see FIG. 13). Further, the second magnet 12 approaches the second sensor 14 so that the magnetic lines of force of the second magnet 12 are parallel to the detection surface 14 a of the second sensor 14. Is turned on in response to the magnetic field lines of the second magnet 12 (see FIG. 13). As a result, it is identified that the first case 1 and the second case 2 are overlapped and folded in a state where the key input unit 1a and the display unit 2a face each other.

Further, as shown in FIG. 2B, the first case 1 and the second case 2 rotate together with the auxiliary case 3a around the first rotating shafts 4 and 5 of the hinge portion 3 and open at an angle of 90 °. As shown in FIG. 10, the first magnet 11 rotates clockwise together with the auxiliary case 3a and approaches the second sensor 14, and the second magnet 12 rotates clockwise together with the auxiliary case 3a. Leave 14 At this time, as shown in FIG. 10, since the first magnet 11 rotates 90 ° clockwise, the first magnet 11 corresponds to the upright state, and the direction of the magnetic lines of force rotates 90 ° so that the second sensor 14 is rotated. It becomes a state parallel to the detection surface 14a.

For this reason, the second sensor 14 is turned on in response to the magnetic lines of force of the first magnet 11 (see FIG. 13). At this time, the first and second magnets 11 and 12 are separated from the first sensor 13, and the first sensor 13 does not react to any magnetic field lines of the first and second magnets 11 and 12, so that it is turned off. (See FIG. 13). As a result, as shown in FIG. 2 (b), the first case 1 and the second case 2 together with the auxiliary case 3a and the first rotation of the hinge part 3 with the key input part 1a and the display part 2a facing each other. A second open state is identified which is rotated about the axes 4 and 5 and opened at an angle of 90 °.

Further, as shown in FIG. 2 (c), when the first case 1 and the second case 2 are further rotated around the first rotation shafts 4 and 5 of the hinge portion 3 and opened at an angle of about 165 °, As shown in FIG. 11, the first magnet 11 rotates clockwise with the auxiliary case 3a to move away from the second sensor 14, and the second magnet 12 rotates clockwise with the auxiliary case 3a to the first sensor 13 side. Move towards. At this time, since the first magnet 11 rotates clockwise and rotates at an angle of about 165 °, the first magnet 11 moves away from the second sensor 14 and the second magnet 12 rotates toward the first sensor 13 side. However, it is not sufficiently close to the first sensor 13 and is away from the first sensor 13.

For this reason, the first sensor 13 is turned off without reacting to the magnetic lines of force of the first and second magnets 11 and 12 (see FIG. 13). Further, the second sensor 14 is turned off without reacting to the magnetic lines of force of the first and second magnets 11 and 12 (see FIG. 13). As a result, as shown in FIG. 2C, the first case 1 and the second case 2 are rotated about the first rotation shafts 4 and 5 of the hinge portion 3 and opened at an angle of about 165 °. 3 is fully opened.

Further, as shown in FIG. 2B, the first case 1 and the second case 2 are opened at an angle of 90 ° together with the auxiliary case 3a around the first rotation shafts 4 and 5 of the hinge portion 3. 2, the second case 2 rotates 180 ° around the second rotating shaft 6 of the hinge portion 3 with respect to the auxiliary case 3 a, and only the second magnet 12 rotates and moves accordingly. The input unit 1a and the display unit 2a do not face each other, and thereafter, as shown in FIG. 2D, the second case 2 rotates around the first rotation shafts 4 and 5 of the hinge unit 3 together with the auxiliary case 3a. Then, as shown in FIG. 12, the second magnet 12 is separated from the first and second sensors 13 and 14 (not shown in FIG. 12), and the first magnet 11 is the first, as shown in FIG. The sensor 13 approaches and responds.

For this reason, the magnetic lines of force of the first magnet 11 are perpendicular to the detection surface 13a of the first sensor 13, and the first sensor 13 is turned on in response to the magnetic lines of force of the first magnet 11 (see FIG. 13). . At this time, the second sensor 14 is turned off without reacting to any magnetic field lines of the first and second magnets 11 and 12 (see FIG. 13). As a result, as shown in FIG. 2D, the first case 1 and the second case 2 are overlapped and folded together with the auxiliary case 3a in a state where the key input unit 1a and the display unit 2a do not face each other. Is identified as being in a reverse closed state. That is, since the detection states by the first and second sensors 13 and 14 are different for each of the first to fourth open / close states, the first to fourth open / close states can be identified.

Thus, according to this mobile phone, when the first magnet 11 provided in the auxiliary case 3a of the second case 2 at a location located in the vicinity of the hinge portion 3 corresponds, it reacts to the lines of magnetic force. The first sensor 13 and the second case 2 rotate with respect to the first case 1 with the hinge 3 as the center, and the direction of the magnetic force lines of the first magnet 11 changes in a direction orthogonal to the first sensor 13 and changes accordingly. Since the second sensor 14 that reacts to the lines of magnetic force is arranged in the first case 1, one wiring of the first and second sensors 13, 14 is connected to the first through the hinge portion 3. The first and second sensors 13 and 14 can be wired in the first case 1 without having to be routed to both the case 1 and the second case 2, whereby the first and second sensors can be wired. The wiring work of 13 and 14 can be simplified.

In this case, the hinge portion 3 includes first rotating shafts 4 and 5 for rotating the first case 1 and the second case 2 from the folded state to the folding direction of the opening direction, and the first rotating shafts 4 and 5. A second rotating shaft 6 that rotates in a direction orthogonal to the rotation direction of the first rotating shaft 6 and a connecting portion 7 that connects the first rotating shafts 4 and 5 and the second rotating shaft 6, and the second case 2 includes a second case 2. Since the auxiliary case 3 a that covers the rotary shaft 6 and the connecting portion 7 and rotates around the first rotary shafts 4 and 5 is provided, the first case 1 and the second case 2 are folded in the folding direction by the hinge portion 3. , And can be rotated in a direction orthogonal to the folding direction, thereby opening and closing in each of the first closed state, the second open state, the third fully open state, and the fourth reverse closed state. Can be made.

Further, in this mobile phone, the first magnet 11 is provided in the auxiliary case 3a of the second case 2 at a location located in the vicinity of the second rotation shaft 6, so that the first rotation shaft 4 of the hinge portion 3, When the first case 1 and the second case 2 are rotated around 5 and opened at an angle of 90 °, the first magnet 11 can cause the second sensor 14 to react with the lines of magnetic force. That is, when the first case 1 and the second case 2 are rotated about the first rotation shafts 4 and 5 of the hinge portion 3 and opened at an angle of 90 °, the first magnet 11 is attached to the second case 2. When the magnetic force line of the first magnet 11 rotates by 90 ° and the direction of the magnetic force line changes by 90 ° by rotating with the auxiliary case 3a to correspond to the second sensor 14, the second sensor 14 can be reacted.

Furthermore, in this mobile phone, the second magnet 12 that generates a magnetic force line in a direction perpendicular to the magnetic force lines of the first magnet 11 is provided on the second rotating shaft 6 of the hinge portion 3 that rotates together with the second case 2. Since it is provided in a state corresponding to the rotational movement locus of the first magnet 11 around the rotation shafts 4 and 5, the first closed state, the second open state, the third fully opened state, Each of the four reverse closed states can be identified. That is, since the first sensor 13 is turned on by the first magnet 11 and the second sensor 14 is turned on by the second magnet 12, the key input unit 1a and the display unit 2a face each other in the first case. It can be identified that the first closed state in which the first case 2 and the second case 2 are overlapped and folded.

Further, since the first sensor 13 is off and the second sensor 14 is on, the first case 1 and the second case 2 are hinged in a state where the key input unit 1a and the display unit 2a face each other. It is possible to identify the second open state in which the first rotation shafts 4 and 5 are rotated about the first rotation shafts 3 and 5 and opened at an angle of 90 °. As described above, when the second case 2 is opened at an angle of 90 ° with respect to the first case 1, one seg is automatically activated, or in a camera-equipped model, the camera is automatically switched to the shooting mode. Can be switched.

Further, since the first sensor 13 is turned off and the second sensor 14 is also turned off, the first case 1 and the second case 2 rotate around the first rotation shafts 4 and 5 of the hinge portion 3. Thus, it can be identified that the third fully opened state is opened at an angle of approximately 165 °. Further, since the first sensor 13 is turned on and the second sensor 14 is turned off, the first case 1 and the second case 2 are not in contact with the key input unit 1a and the display unit 2a. It can be identified that the fourth reverse closed state is overlapped and folded. Thereby, since the detection states by the first and second sensors 13 and 14 are different for each of the first to fourth open / close states, the first to fourth open / close states can be reliably identified. it can.

Is disposed at a position rotated clockwise by an angle of 90 ° with respect to the first magnet 21 on the rotational movement trajectory of the first magnet 21 around the center, and is orthogonal to the first magnet 21. The magnetic lines of force of the second magnet 22 are always orthogonal to the magnetic lines of force of the first magnet 21 and are disposed in the auxiliary case 3a.

As shown in FIG. 16A, the first sensor 23 is composed of a magnetoresistive element (MR element: Magneto Resistance element) that reacts to a magnetic force line parallel to the detection surface 23a. As shown in FIG. 14, when the first case 1 and the second case 2 are overlapped and closed, the first sensor 23 is placed at a position in the first case 1 to which the first magnet 21 corresponds. It is provided so that the first magnet 21 reacts to the lines of magnetic force when it approaches and responds.

As shown in FIG. 16B, the second sensor 24 is composed of a Hall element that reacts to a magnetic force line perpendicular to the detection surface 24a. As shown in FIG. 14, the second sensor 24 has a first case 1 in the first case 1 corresponding to the second magnet 22 when the first case 1 and the second case 2 are overlapped and closed. It is provided at a location corresponding to the rotational movement locus of the first magnet 21 around the first rotation shafts 4 and 5 of the hinge portion 3 in the vicinity of the sensor 23, and when the second magnet 22 corresponds, In addition to reacting to the magnetic lines of force, the first magnet 21 is also configured to react to the magnetic lines of force when the first magnet 21 rotates and moves at an angle of 90 °.

That is, as shown in FIG. 14, the second sensor 24 reacts to the magnetic lines of force of the second magnet 22 when the first case 1 and the second case 2 are overlapped and closed, as shown in FIG. As shown, when the first case 1 and the second case 2 are rotated about the first rotation shafts 4 and 5 of the hinge portion 3 and opened at an angle of 90 °, the first magnet 21 is moved to the second case. The magnetic field of the first magnet 21 is rotated by 90 ° to change the direction of the magnetic line of force by changing the direction of the magnetic line of force. Also configured to react.

Next, the operation of this mobile phone will be described.
First, as shown in FIG. 2A, the first case 1 and the second case 2 are placed with the key input unit 1a of the first case 1 and the display unit 2a of the second case 2 facing each other. When overlapped and folded together with the auxiliary case 3a, the first magnet 21 corresponds to the first sensor 23 and the second magnet 22 corresponds to the second sensor 24, as shown in FIG.

At this time, the first magnet 21 approaches and responds to the first sensor 23 so that the magnetic lines of force of the first magnet 21 are parallel to the detection surface 23a of the first sensor 23. 23 is turned on in response to the magnetic field lines of the first magnet 21. Further, the second magnet 22 approaches the second sensor 24 so that the magnetic lines of force of the second magnet 22 are perpendicular to the detection surface 24 a of the second sensor 24. Is turned on in response to the magnetic field lines of the second magnet 22. As a result, it is identified that the first case 1 and the second case 2 are overlapped and folded in a state where the key input unit 1a and the display unit 2a face each other.

Further, as shown in FIG. 2B, the first case 1 and the second case 2 rotate together with the auxiliary case 3a around the first rotation shafts 4 and 5 of the hinge portion 3 to an angle of 90 °. When opened, the first magnet 21 rotates clockwise together with the auxiliary case 3a to approach the second sensor 24, and the second magnet 22 rotates clockwise together with the auxiliary case 3a as shown in FIG. Move away from sensor 24. At this time, as shown in FIG. 17, the first magnet 21 rotates 90 ° clockwise, so that the first magnet 21 stands up, and the direction of the lines of magnetic force rotates 90 ° so that the second sensor 24 rotates. It becomes a state perpendicular to the detection surface 24a.

For this reason, the second sensor 24 is turned on in response to the magnetic lines of force of the first magnet 21. At this time, the first and second magnets 21 and 22 are separated from the first sensor 23, and the first sensor 23 does not react to any of the magnetic lines of force of the first and second magnets 21 and 22. . As a result, as shown in FIG. 2 (b), the first case 1 and the second case 2 are connected to the first rotating shaft 4 of the hinge portion 3, with the key input portion 1a and the display portion 2a facing each other. 5 is identified as being in the second open state rotated about 5 and opened at an angle of 90 °.

Further, as shown in FIG. 2C, when the first case 1 and the second case 2 are further rotated around the first rotation shafts 4 and 5 of the hinge portion 3 and opened at an angle of about 165 °. 18, the first magnet 21 rotates clockwise together with the auxiliary case 3a to move away from the second sensor 24, and the second magnet 22 rotates together with the auxiliary case 3a clockwise to move to the first sensor 23 side. Rotate towards At this time, since the first magnet 21 rotates clockwise and rotates at an angle of about 165 °, the second magnet 22 rotates toward the first sensor 23, but it is sufficient for the first sensor 13. It will be in the state away from the 2nd sensor 24, without approaching.

For this reason, the first sensor 23 is turned off without reacting to the magnetic lines of force of the second magnet 22. The second sensor 24 is also turned off without reacting to the magnetic field lines of the first magnet 21. As a result, as shown in FIG. 2C, the first case 1 and the second case 2 rotate about the first rotation shafts 4 and 5 of the hinge portion 3 and are opened at an angle of about 165 °. A third fully open state is identified.

Further, as shown in FIG. 2B, the first case 1 and the second case 2 are opened at an angle of 90 ° together with the auxiliary case 3a around the first rotation shafts 4 and 5 of the hinge portion 3. 2, the second case 2 rotates 180 ° around the second rotating shaft 6 of the hinge portion 3 with respect to the auxiliary case 3 a, and only the second magnet 22 rotates and moves accordingly. The input unit 1a and the display unit 2a do not face each other, and thereafter, as shown in FIG. 2D, the second case 2 and the auxiliary case 3a are centered on the first rotating shafts 4 and 5 of the hinge unit 3. As shown in FIG. 19, the second magnet 22 is separated from the first and second sensors 23 and 24 (not shown in FIG. 19), and the first magnet 21 is One sensor 23 approaches and responds.

For this reason, the magnetic lines of force of the first magnet 21 are perpendicular to the detection surface 23 a of the first sensor 23, and the first sensor 23 is turned on in response to the magnetic lines of force of the first magnet 21. At this time, the second sensor 24 is turned off without reacting to any magnetic field lines of the first and second magnets 21 and 22. As a result, as shown in FIG. 2D, the first case 1 and the second case 2 are folded together with the auxiliary case 3a in a state where the key input unit 1a and the display unit 2a do not face each other. 4 is identified as the reverse closed state. That is, since the detection states by the first and second sensors 23 and 24 are different for the first to fourth open / close states, the first to fourth open / close states can be identified.

As described above, also in this mobile phone, when the first magnet 21 provided in the auxiliary case 3a of the second case 2 located near the hinge portion 3 corresponds to the first magnetic field 21 that reacts to the lines of magnetic force. When the second case 2 rotates relative to the first case 1 around the 1 sensor 23 and the hinge portion 3 and the direction of the magnetic lines of the first magnet 21 changes in a direction perpendicular to the corresponding direction, the changed magnetic field lines Since the second sensor 24 that reacts to the first case 1 is arranged in the first case 1, as in the first embodiment, one of the first and second sensors 23 and 24 is passed through the hinge portion 3. There is no need to route the wiring to both the first case 1 and the second case 2, and the first and second sensors 23 and 24 can be wired in the first case 1, thereby the first and second cases. Simplification of wiring work of each sensor 23, 24 It is possible to achieve.

Also in this case, the second magnet 22 that generates a magnetic force line in a direction perpendicular to the magnetic force lines of the first magnet 21 is provided on the second rotating shaft 6 of the hinge portion 3 that rotates together with the second case 2. Since it is provided in a state corresponding to the rotational movement trajectory of the first magnet 21 centered on 4, 5, the first closed state, the second open state, the third fully open state, the fourth Each state in the reverse closed state can be identified. That is, since the first sensor 23 is turned on by the first magnet 21 and the second sensor 24 is turned on by the second magnet 22, the key input unit 1 a and the display unit 2 a face each other in the first case. It can be identified that the first closed state in which the first case 2 and the second case 2 are overlapped and folded.

In addition, since the first sensor 23 is off and the second sensor 24 is on, the first case 1 and the second case 2 are hinged in a state where the key input unit 1a and the display unit 2a face each other. It is possible to identify the second open state in which the first rotation shafts 4 and 5 are rotated about the first rotation shafts 3 and 5 and opened at an angle of 90 °. As described above, when the second case 2 is opened at an angle of 90 ° with respect to the first case 1, as in the first embodiment, one seg is automatically activated, or in a model equipped with a camera, it depends on the camera. You can automatically switch to shooting mode.

Further, since the first sensor 23 is turned off and the second sensor 24 is also turned off, the first case 1 and the second case 2 rotate around the first rotation shafts 4 and 5 of the hinge portion 3. Thus, it can be identified that the third fully opened state is opened at an angle of approximately 165 °. Further, since the first sensor 23 is turned on and the second sensor 24 is turned off, the first case 1 and the second case 2 are not in contact with the key input unit 1a and the display unit 2a. It can be identified that the fourth reverse closed state is overlapped and folded together with the auxiliary case 3a. Thereby, since the detection states by the first and second sensors 23 and 24 are different for each of the first to fourth open / close states, the first to fourth open / close states can be reliably identified. it can.

(Embodiment 3)
Next, a third embodiment in which the present invention is applied to a mobile phone will be described with reference to FIGS. Also in this case, the same portions as those in the first embodiment shown in FIGS.
As shown in FIG. 20, in this cellular phone, the installation positions of the first magnet 31 and the second magnet 32 are different from those of the first embodiment. Accordingly, the installation positions of the first sensor 33 and the second sensor 34 are changed. The configuration is changed, and the configuration other than this is almost the same as that of the first embodiment.

In this case, the first magnet 31 and the second magnet 32 generate magnetic lines of force in the thickness direction, as shown in FIG. The first magnet 31 is provided in the auxiliary case 3 a of the second case 2 at a location located in the vicinity of the connecting portion 7 in the hinge portion 3, and assists around the first rotating shafts 4 and 5 of the hinge portion 3. It is configured to rotate together with the case 3a. As in the first embodiment, the second magnet 32 is in a state corresponding to the rotational movement locus of the first magnet 31 around the first rotation shafts 4 and 5 of the hinge portion 3 in the same manner as in the first embodiment. The rotating shaft 6 is provided.

Further, the second magnet 32 is attached to an attachment piece 12a (see FIG. 6) provided at an angle of 45 ° on the second rotating shaft 6, and as shown in FIG. When the second case 2 overlaps with the auxiliary case 3a and is folded, the second case 2 corresponds to the rotational movement locus of the first magnet 31 around the first rotation shafts 4 and 5. That is, as shown in FIG. 20, the second magnet 32 has a 45 ° angle with respect to the first magnet 31 on the rotational movement trajectory of the first magnet 31 around the first rotation shafts 4 and 5. By being arranged at a position rotated in the rotating direction and inclined by 45 ° with respect to the first magnet 31, the magnetic lines of force of the second magnet 32 are always inclined by 45 ° with respect to the magnetic lines of force of the first magnet 31. It is arranged in the auxiliary case 3a.

As shown in FIG. 22, the first sensor 33 and the second sensor 34 are Hall elements that react to magnetic lines of force perpendicular to the detection surfaces 33a and 34a. Then, as shown in FIG. 20, the first sensor 33 is connected to the first case 1 and the second case 2 with the key input unit 1a of the first case 1 and the display unit 2a of the second case 2 facing each other. When the first magnet 31 is closed together with the auxiliary case 3a and closed, the first magnet 31 is provided in the corresponding first case 1 so that it reacts to the lines of magnetic force when the first magnet 31 approaches and responds. It is configured.

As shown in FIG. 20, the second sensor 34 is in the first case 1 corresponding to the second magnet 32 when the first case 1 and the second case 2 are overlapped and closed together with the auxiliary case 3a. In the vicinity of the first sensor 33 and at a location corresponding to the rotational movement locus of the first magnet 31 centered on the first rotation shafts 4 and 5, and when the second magnet 32 corresponds, the lines of magnetic force thereof are provided. It is configured to react to.

In this case, as shown in FIG. 20, the second sensor 34 reacts to the magnetic lines of force of the second magnet 32 when the first case 1 and the second case 2 are overlapped and closed together with the auxiliary case 3a. As shown in FIG. 23, when the first case 1 and the second case 2 rotate around the first rotation shafts 4 and 5 of the hinge portion 3 together with the auxiliary case 3a and open at an angle of 45 °, The first magnet 31 rotates and moves to correspond to the second sensor 34, and the line of magnetic force of the first magnet 31 rotates 45 ° to change the direction of the line of magnetic force. It is configured to react.

Next, the operation of this mobile phone will be described.
First, as shown in FIG. 2A, the first case 1 and the second case 2 are placed with the key input unit 1a of the first case 1 and the display unit 2a of the second case 2 facing each other. When overlapped with the auxiliary case 3a and folded, the first magnet 31 corresponds to the first sensor 33 and the second magnet 32 corresponds to the second sensor 34, as shown in FIG.

At this time, when the first magnet 31 approaches the first sensor 33 and responds, the magnetic lines of force of the first magnet 31 are perpendicular to the detection surface of the first sensor 33. Is turned on in response to the magnetic field lines of the first magnet 31 (see FIG. 27). Further, the second magnet 32 approaches the second sensor 34 so that the magnetic lines of force of the second magnet 32 are perpendicular to the detection surface of the second sensor 34. Therefore, the second sensor 34 It turns on in response to the magnetic field lines of the second magnet 32 (see FIG. 27). As a result, it is identified that the first case 1 and the second case 2 are overlapped and folded in a state where the key input unit 1a and the display unit 2a face each other.

Further, as shown in FIG. 2B, the first case 1 and the second case 2 rotate together with the auxiliary case 3a around the first rotation shafts 4 and 5 of the hinge portion 3 to an angle of 45 °. When opened, the second magnet 32 rotates clockwise to move away from the second sensor 34 and the first magnet 31 rotates clockwise to approach the second sensor 34 as shown in FIG. At this time, since the first magnet 31 rotates clockwise by 45 °, the first magnet 31 tilts by 45 ° to correspond to the second sensor, and the direction of the magnetic force line of the first magnet 31 rotates by 45 °. The two sensors 34 are perpendicular to the detection surface 34a.

Therefore, the second sensor 34 is turned on in response to the magnetic lines of force of the first magnet 31 (see FIG. 27). At this time, the second magnet 32 moves away from the second sensor 34, and the second sensor 34 does not react to the magnetic lines of force of the first and second magnets 31 and 32, so that it is turned off (see FIG. 27). . As a result, as shown in FIG. 2B, the first case 1 and the second case 2 together with the auxiliary case 3a and the first case 1 of the hinge portion 3 are in a state where the key input portion 1a and the display portion 2a face each other. A second open state is identified in which the rotary shafts 4 and 5 are rotated about the rotation shafts 4 and 5 and opened at an angle of 45 °.

Further, as shown in FIG. 2C, when the first case 1 and the second case 2 are further rotated around the first rotation shafts 4 and 5 of the hinge portion 3 and opened at an angle of about 165 °. As shown in FIG. 24, the first magnet 31 and the second magnet 32 rotate clockwise together with the auxiliary case 3a and rotate to a position sufficiently separated from the first sensor 33 and the second sensor 34.

For this reason, the first sensor 33 is turned off without reacting to any magnetic field lines of the first magnet 31 and the second magnet 32 (see FIG. 27). Further, the second sensor 34 is also turned off without reacting to any magnetic field lines of the first magnet 31 and the second magnet 32 (see FIG. 27). As a result, as shown in FIG. 2 (c), the first case 1 and the second case 2 rotate about the first rotation shafts 4 and 5 of the hinge portion 3 together with the auxiliary case 3a, so that the angle is approximately 165 °. Identifying a third fully open state opened at an angle.

Further, as shown in FIG. 2 (b), the first case 1 and the second case 2 are opened together with the auxiliary case 3a by 45 ° around the first rotating shafts 4 and 5 of the hinge portion 3. In this state, the second case 2 rotates 180 ° around the second rotation shaft 6 of the hinge portion 3 with respect to the auxiliary case 3a, and only the second magnet 32 rotates and moves accordingly, and the key input portion 1a. And the display portion 2a do not face each other, and thereafter, as shown in FIG. 2 (d), the second case 2 rotates around the first rotation shafts 4 and 5 of the hinge portion 3 together with the auxiliary case 3a. When overlapped and folded, the second magnet 32 moves away from the first and second sensors 33 and 34, and the first magnet 31 approaches the first sensor 33 as shown in FIGS. To do.

For this reason, the magnetic lines of force of the first magnet 31 are perpendicular to the detection surface 33a of the first sensor 33, and the first sensor 33 is turned on in response to the magnetic lines of force of the first magnet 31 (see FIG. 27). . At this time, the second sensor 34 is turned off without reacting to the magnetic lines of force of the first and second magnets 31 and 32 (see FIG. 27). As a result, as shown in FIG. 2D, the first case 1 and the second case 2 are folded together with the auxiliary case 3a in a state where the key input unit 1a and the display unit 2a do not face each other. 4 is identified as the reverse closed state. That is, since the detection states by the first and second sensors 33 and 34 are different for the first to fourth open / close states, the first to fourth open / close states can be identified.

Thus, also in this mobile phone, when the first magnet 31 provided in the auxiliary case 3a of the second case 2 at a location located in the vicinity of the hinge portion 3 corresponds, the first magnetic field reacts to the lines of magnetic force. When the second case 2 rotates together with the auxiliary case 3a with respect to the first case 1 with the sensor 33 and the hinge 3 as the center, the direction of the magnetic lines of the first magnet 31 changes by 45 ° and changes. Since the second sensor 34 that reacts to the first case 1 is arranged in the first case 1, as in the first embodiment, one of the first and second sensors 33 and 34 is passed through the hinge portion 3. There is no need to route the wiring to both the first case 1 and the second case 2, and the first and second sensors 33 and 34 can be wired in the first case 1, thereby the first and second cases. Wiring work of each sensor 33, 34 of 2 It can be simplified.

Also in this case, the second magnet 32 that generates a magnetic force line inclined by 45 ° with respect to the magnetic force line of the first magnet 31 is provided on the second rotating shaft 6 of the hinge portion 3 that rotates together with the second case 2. Since it is provided in a state corresponding to the rotational movement trajectory of the first magnet 31 centered on 4 and 5, the first closed state, the second open state, the third fully open state, the fourth reverse Each closed state can be identified. That is, since the first sensor 33 is turned on by the first magnet 31 and the second sensor 34 is turned on by the second magnet 32, the key input unit 1a and the display unit 2a face each other in the first case. It can be identified that the first closed state in which the first case 2 and the second case 2 are overlapped and folded.

In addition, since the first sensor 33 is off and the second sensor 34 is on, the first case 1 and the second case 2 are hinged in a state where the key input unit 1a and the display unit 2a face each other. It is possible to identify the second open state that is rotated about the first rotary shafts 4 and 5 and opened at an angle of 45 °. Thus, when the second case 2 is opened at an angle of 45 ° with respect to the first case 1, the first case 1 and the second case 2 are not opened at an angle of 165 °, but a glimpse of the display unit 2a Postcards, so you can quickly see information such as time, which is convenient.

Further, since the first sensor 33 is turned off and the second sensor 34 is also turned off, the first case 1 and the second case 2 rotate around the first rotation shafts 4 and 5 of the hinge portion 3. Thus, it can be identified that the third fully opened state is opened at an angle of approximately 165 °. Further, since the first sensor 33 is on and the second sensor 34 is off, the first case 1 and the second case 2 are in the auxiliary case 3a in a state where the key input unit 1a and the display unit 2a do not face each other. It can be identified that the fourth reverse closed state is overlapped and folded together. Thereby, since the detection states by the first and second sensors 33 and 34 are different for each of the first to fourth open / close states, the first to fourth open / close states can be accurately identified. it can.

(Embodiment 4)
Next, a fourth embodiment in which the present invention is applied to a mobile phone will be described with reference to FIGS. Also in this case, the same portions as those in the first embodiment shown in FIGS.
As shown in FIGS. 28 to 30, this mobile phone has a configuration in which the third sensor 40 is provided in the first case 1, and the configuration other than this is substantially the same as that of the first embodiment.

The third sensor 40 is composed of a Hall element that reacts to a magnetic field line perpendicular to the detection surface. As shown in FIG. 29, the third sensor 13 is located away from the first sensor 11 and the second sensor 12, and the first case 1 and the second case 2 are the second rotation shaft of the hinge portion 3. When the key input unit 1a and the display unit 2a are not in contact with each other when the key input unit 1a and the display unit 2a are not in contact with each other, the second magnet 12 is provided in the first case 1 at the corresponding location. When the magnet 12 approaches and responds, it reacts to the line of magnetic force.

That is, the third sensor 40 is in a second open state in which the first case 1 and the second case 2 are opened at an angle of 90 ° together with the auxiliary case 3a around the first rotating shafts 4 and 5 of the hinge portion 3. Thus, the second case 2 is rotated by 180 ° about the second rotation shaft 6 of the hinge portion 3 with respect to the auxiliary case 3a, and only the second magnet is rotationally moved along with this, and the key input portion 1a is displayed. When the part 2a does not face the second magnet 12, the second magnet 12 rotated around the second rotating shaft 6 is provided in the first case 1 at a corresponding location. The third sensor 40 is configured so that the second case 2 and the auxiliary case 3a are centered on the first rotation shafts 4 and 5 with respect to the first case 1 in a state where the key input unit 1a and the display unit 2a do not face each other. When it is rotated and folded, the second magnet 12 is configured so as not to move away.

In such a cellular phone, there is an effect similar to that of the first embodiment, and the first case 1 and the second case 2 are 90 ° together with the auxiliary case 3a around the first rotating shafts 4 and 5 of the hinge portion 3. In the second open state opened at an angle, the second case 2 rotates 180 ° around the second rotating shaft 6 of the hinge part 3 with respect to the auxiliary case 3a, and only the second magnet 12 rotates accordingly. Since the second magnet 12 approaches the third sensor 40 when the key input unit 1a and the display unit 2a do not face each other after moving, the third sensor 40 reacts to the magnetic field lines of the second magnet 12. And turned on (see FIG. 30).

As a result, when the first sensor 13 and the second sensor 14 are turned off and only the third sensor 40 is turned on, the first case 1 and the second case 2 are opened at an angle of 90 °. In the open state, the second case 2 is rotated by 180 ° around the second rotation shaft 6 of the hinge portion 3 with respect to the auxiliary case 3a, and the key input portion 1a and the display portion 2a are identified as not facing each other. To do.

Further, in the second open state in which the first case 1 and the second case 2 are opened at an angle of 90 °, the key input unit 1a and the display unit 2a do not face each other, and the second case 2 is the auxiliary case 3a. At the same time, the second magnet 12 is not separated from the third sensor 40 when the first case 1 is in the fourth reverse closed state, which is rotated about the first rotation shafts 4 and 5 and folded. The third sensor 40 is turned off without reacting to the magnetic field lines of the second magnet 12 (see FIG. 30). At this time, the first magnet 11 corresponds to the first sensor 13 and turns on the first sensor 13 (see FIG. 30). Thus, when the first sensor 13 is turned on, the second sensor 14 is turned off, and the third sensor 40 is also turned off, the second case 2 is in a state where the key input unit 1a and the display unit 2a do not face each other. The fourth case is identified as being in a fourth reverse closed state in which the first case 1 together with the auxiliary case 3a is rotated around the first rotation shafts 4 and 5 and folded.

Further, the third sensor 40 includes a first closed state in which the first case 1 and the second case 2 are overlapped and folded with the key input unit 1a and the display unit 2a facing each other. A second open state in which the second case 2 rotates together with the auxiliary case 3a and opens at an angle of 90 °, and a third open state in which the first case 1 and the second case 2 rotate and open at an angle of 165 °. In the fully open state, the first magnet 11 and the second magnet 12 are located at a distance from each other, so that the first to third states are turned off (see FIG. 30). Also in this case, the detection states by the first to third sensors 13, 14, and 40 are different for each of the first to fourth open / close states.

As described above, in this mobile phone, in addition to the first sensor 11 and the second sensor 12, the third sensor 40 that reacts to the magnetic lines of force of the second magnet 12 is provided in the first case 1 as the first and second sensors 12. Since the second magnet 12 is provided on the rotational movement locus in which the second magnet 12 rotates around the second rotation shaft 6 of the hinge portion 3 at a position away from each of the two sensors 13 and 14. Similarly, it is not necessary to route any of the wirings of the first to third sensors 13, 14, and 40 through the hinge portion 3 to both the first case 1 and the second case 2. The sensors 13, 14, 40 can be wired in the first case 1, thereby simplifying the wiring work of the first to third sensors 13, 14, 40 even if the third sensor 40 is added. Can be achieved.

Also in this case, as in the first embodiment, the first magnet 11 is provided in the auxiliary case 3 a of the second case 2, the second magnet 12 is provided on the second rotating shaft 6 of the hinge portion 3, and the inside of the first case 1 Are provided with the first to third sensors 13, 14, and 40, so that the first closed state, the second open state, the third fully opened state, and the fourth reverse closed state are identified. In addition, the second case 2 assists in the second open state in which the first case 1 and the second case 2 are opened at an angle of 90 ° around the first rotating shafts 4 and 5 of the hinge portion 3. A state where the key input unit 1a and the display unit 2a do not face each other can be identified by rotating 180 degrees around the second rotation axis 6 of the hinge unit 3 with respect to the case 3a.

That is, the first sensor 13 is turned on by the first magnet 11, the second sensor 14 is turned on by the second magnet 12, and the third sensor 40 is turned off, so that the key input unit 1a and the display unit 2a face each other. In this state, it can be identified that the first case 1 and the second case 2 are in the first closed state in which they are overlapped and folded. Further, when the first sensor 13 is turned off, the second sensor 14 is turned on, and the third sensor 40 is turned off, the first case 1 and the second case 1 are brought into contact with the key input unit 1a and the display unit 2a. It can be identified that the second case 2 is in the second open state that is rotated about the first rotation shafts 4 and 5 of the hinge portion 3 and opened at an angle of 90 °.

In addition, since the first sensor 13 is turned off, the second sensor 14 is also turned off, and the third sensor 40 is also turned off, the first case 1 and the second case 2 are connected to the first rotating shaft 4 of the hinge portion 3. It can be identified that the third fully opened state is rotated about 5 and opened at an angle of approximately 165 °. Further, when the first sensor 13 is turned off, the second sensor 14 is also turned off, and the third sensor 40 is turned on, the first case 1 and the first case 1 around the first rotation shafts 4 and 5 of the hinge portion 3 are turned on. In the second open state in which the case 2 is opened at an angle of 90 °, the second case 2 is rotated 180 ° around the second rotation shaft 6 of the hinge portion 3 with respect to the auxiliary case 3a, and the key input portion It can be identified that 1a and the display unit 2a are not facing each other.

Further, the first sensor 13 is turned on, the second sensor 14 is turned off, and the third sensor 40 is also turned off, so that the first case 1 and the second case 1 are not in contact with the key input unit 1a and the display unit 2a. It can be identified that the second case 2 is in the fourth reverse closed state in which the two cases 2 are overlapped and folded. Thereby, since the detection states by the first to third sensors 13 and 14 are different for the first to fourth open / close states, the first to fourth open / close states can be reliably identified. it can.

In the first to fourth embodiments, the hinge portion 3 includes the first rotating shafts 4 and 5 that rotate the first case 1 and the second case 2 in the folding direction, and the first rotating shafts 4 and 5. Although the case where it is a biaxial hinge structure provided with the 2nd rotating shaft 6 which rotates in the orthogonal direction with respect to the 1st rotating shaft 4, 5 and the 2nd rotating shaft 6 was described, it was not necessarily It is not necessary to have a biaxial hinge structure, and the present invention can also be applied to a uniaxial hinge structure provided with only first rotating shafts 4 and 5 that rotate the first case 1 and the second case 2 in the folding direction.

In this case, the first magnet 11 is provided in the second case 2 at a location located in the vicinity of the first rotating shafts 4 and 5 with the first case 1 and the second case 2 overlapped and folded. The first and second sensors 13 and 14 are separated by a predetermined distance along the rotational movement locus of the first magnet 11 in the first case 1 corresponding to the rotational movement locus of the first magnet 11. What is necessary is just to use the provided structure.

In the first to fourth embodiments, the case where the present invention is applied to a mobile phone has been described. However, the present invention is not necessarily a mobile phone. For example, a PDA (Personal Digital Assistant), a notebook personal computer, a wearable personal computer, a camera, It can be widely applied to various electronic devices such as calculators and electronic dictionaries.
