  As illustrated in FIG. 2A, the first housing 12 includes a first magnet 30 and holding magnets 32, 34, 36, and 38. That is, each magnet is arranged inside the first housing 12. Further, as shown in FIG. 2B, the second housing 14 includes a second magnet 40 and holding magnets 42, 44, 46, and 48. That is, each magnet is arranged inside the second housing 14.

  In addition, as shown in FIG. 2C, the first magnet 30 and the holding magnets 32, 34, 36, and 38 are on the back side of the first housing 12, that is, in the thickness direction of the first housing 12. The display unit 16 is disposed at the end opposite to the surface on which the display unit 16 is disposed. The second magnet 40 and the holding magnets 42, 44, 46, and 48 are surfaces on which the numeric keypad 18 is disposed in the front side of the second housing 14, that is, in the thickness direction of the second housing 14. Arranged on the side. Next, each part will be described.

  The first magnet 30 is a permanent magnet that is in the form of a sheet and is multipolarly magnetized, and is arranged in the same size as the display unit 16. Specifically, the first magnet 30 is disposed in a region excluding the outer edge of the back surface of the first housing 12. The magnetized state of the first magnet 30 will be described later.

  Each of the holding magnet 32, the holding magnet 34, the holding magnet 36, and the holding magnet 38 is composed of two permanent magnets, and each of the two long sides on the back surface of the first housing 12. Are arranged along. Specifically, the holding magnet is arranged between one long side of the back surface of the first housing 12, that is, between the end of the back surface and the first magnet 30, from the receiver 22 side toward the operation button 19 side. 32, the holding magnet 34, the holding magnet 36, and the holding magnet 38 are arranged in this order. The holding magnet 32, the holding magnet 34, the holding magnet 36, and the holding magnet 38 are arranged in this order on the other long side of the back surface of the first housing 12 from the receiver 22 side toward the operation button 19 side. Is arranged in. Moreover, each holding magnet is arrange | positioned in the symmetrical position. The holding magnet 32 and the holding magnet 34 are arranged at the same interval as the holding magnet 36 and the holding magnet 38. Further, the holding magnet 36 and the holding magnet 38 are arranged in a region facing the second housing 14 even when the mobile phone 10 is in an open state. Further, the holding magnet 32 and the holding magnet 36 are arranged in a direction in which the surface facing the back surface of the first housing 12 is the same magnetic pole. Both the holding magnet 34 and the holding magnet 38 are arranged so that the surface facing the back surface of the first housing 12 is the same magnetic pole.

  The second magnet 40 is a sheet-like and multipolar magnetized permanent magnet, and is disposed in the area of the surface of the second housing 14 where the numeric keypad 18 is not disposed. The 2nd magnet 40 is arrange | positioned in the area | region except the outer edge of the area | region where the numeric keypad 18 is not arrange | positioned among the surfaces. Further, the length of the surface of the second magnet 40 in the short side direction is the same as that of the first magnet 30. The magnetized state of the second magnet 40 will be described later.

  The holding magnet 42, the holding magnet 44, the holding magnet 46, and the holding magnet 48 are each composed of two permanent magnets, and each of the two long sides on the surface of the second housing 14. Are arranged along. Specifically, the numeric keypad from the side where the second magnet 40 is provided between one long side of the surface of the second housing 14, that is, between the edge of the surface and the second magnet 40 or the numeric keypad 18. The holding magnet 42, the holding magnet 44, the holding magnet 46, and the holding magnet 48 are arranged in this order toward the side where the 18 is provided. Similarly, the holding magnet 42, the holding magnet 44, the holding magnet 46, and the holding magnet 48 are arranged in this order on the other long side of the surface of the second housing 14. Each holding magnet is arranged at a symmetrical position. Further, the holding magnet 42, the holding magnet 44, the holding magnet 46, and the holding magnet 48 are configured such that the holding magnet 42 and the holding magnet 32 face each other when the mobile phone 10 is in a closed state. The holding magnet 44 and the holding magnet 34 face each other, the holding magnet 46 and the holding magnet 36 face each other, and the holding magnet 48 and the holding magnet 38 are arranged to face each other. Further, the holding magnet 42, the holding magnet 44, the holding magnet 46, and the holding magnet 48 are attracted between the magnets of the first housing 12 that face each other when the mobile phone 10 is in the closed state. The magnetic poles are arranged in the direction of the magnetic force.

  Next, as shown in FIG. 3A, the first magnet 30 is magnetized in multiple poles so that one magnetic pole extends in parallel to the sliding direction. That is, the first magnet 30 has a short side in the direction orthogonal to the sliding direction and a long side in the direction parallel to the sliding direction, and a plurality of magnetic poles on the strip are arranged in parallel in the direction orthogonal to the sliding direction. It has a configuration. In other words, in the direction perpendicular to the sliding direction, the first magnet 30 has the north and south poles alternately changing from one end to the other end, and in the direction parallel to the sliding direction. One magnetic pole extends. One magnetic pole on the strip is magnetized to a different magnetic pole from other magnetic poles adjacent in the direction orthogonal to the sliding direction.

  Similarly to the first magnet 30, the second magnet 40 is also magnetized in multiple poles with one magnetic pole extending in parallel to the sliding direction, as shown in FIG. 3-2. That is, the second magnet 40 has a short side in the direction orthogonal to the sliding direction and a long side in the direction parallel to the sliding direction, and a plurality of magnetic poles on the strip are arranged in parallel in the direction orthogonal to the sliding direction. It has a configuration. That is, in the direction perpendicular to the sliding direction, the second magnet 40 alternately changes the N pole and the S pole from one end to the other end, and in the direction parallel to the sliding direction. One magnetic pole extends. One magnetic pole on the strip is magnetized to a different magnetic pole from other magnetic poles adjacent in the direction orthogonal to the sliding direction.

  As shown in FIG. 3C, both the first magnet 30 and the second magnet 40 are magnetized only on the surface facing the outside of the housing. That is, the first magnet 30 and the second magnet 40 are single-sided multipolar magnets whose surfaces facing the center of the housing are not magnetized.

  Here, when the back surface of the first housing 12 and the front surface of the second housing 14 face each other, the mobile phone 10 has a first magnet 30 and a second magnet 40 as shown in FIG. Face to face. At this time, the portion of the first magnet 30 magnetized at the N pole faces the portion of the second magnet 40 magnetized at the S pole, and the portion of the first magnet 30 magnetized at the S pole It faces the portion magnetized in the N pole of the second magnet 40. An attractive force is generated between the first magnet 30 and the second magnet 40.

  The mobile phone 10 is configured as described above, and the first magnet 30 and the second magnet 40 have the first magnet 12 and the second housing 14 because the magnetized magnetic poles do not change in the sliding direction. , The attraction force continues to be generated between the first magnet 30 and the second magnet 40. That is, the relationship shown in FIG. 3C is maintained between the first magnet 30 and the second magnet 40. Further, the attractive force acting between the magnetic pole of the first magnet 30 and the magnetic pole of the second magnet 40 limits the movement in the direction orthogonal to the sliding direction. As described above, the first magnet 30 and the second magnet 40 move in the sliding direction between the first housing 12 and the second housing 14 while adsorbing the first housing 12 and the second housing 14. It becomes the rail of.

  As a result, the mobile phone 10 moves the first casing 12 and the second casing 14 relative to each other while connecting the first casing 12 and the second casing 14 without providing a mechanical engagement portion. Thus, it can be moved in the sliding direction. Further, as long as it moves in the sliding direction, the facing magnetic poles do not change between the first magnet 30 and the second magnet 40, so that a force in a direction separating the first housing 12 and the second housing 14 is generated. This can be suppressed.

  Moreover, since both the 1st magnet 30 and the 2nd magnet 40 are permanent magnets, it is not necessary to change a magnetic pole using an electromagnet. Thereby, the apparatus configuration can be simplified and can be realized without using the power of the mobile phone 10.

  In addition, since the mobile phone 10 has a configuration in which the first casing 12 and the second casing 14 are attracted (connected) only by magnetic force, the first casing 12 and the second casing 14 can be connected to the first casing 12 only by applying a certain external force. The two housings 14 can be separated. For example, by moving the first casing 12 and the second casing 14 by a fixed distance (the width of one magnetic pole) in a direction orthogonal to the sliding direction, the first magnet 30 and the second magnet 40 A repulsive force can be generated between them. Thereby, the 1st housing | casing 12 and the 2nd housing | casing 14 can be isolate | separated. Similarly, the first housing 12 and the second housing 14 are simply brought close to each other with a certain positional relationship, that is, the magnetic poles of the first magnet 30 and the second magnet 40 face each other with the opposite magnetic poles. The first housing 12 and the second housing 14 can be adsorbed (connected). As described above, the mobile phone 10 can easily connect and disconnect the first casing 12 and the second casing 14.

  Furthermore, by providing holding magnets 32, 34, 36, 38, 42, 44, 46, 48, as shown in FIG. 4A, when the mobile phone 10 is in the closed position, the holding magnet 32 is provided. And holding magnet 42 face each other, holding magnet 34 and holding magnet 44 face each other, holding magnet 36 and holding magnet 46 face each other, and holding magnet 38 and holding magnet 48 face each other. To do. As a result, an attractive force is generated between the holding magnets. Thereby, the relative position of the cellular phone 10 in the closed state can be made difficult to shift.

  Further, as shown in FIG. 4B, when the mobile phone 10 is in the open state and is in a state where it is moved to the end of the assumed slide area, the holding magnet 36 and the holding magnet 42 faces the holding magnet 38 and the holding magnet 44 face each other. As a result, an attractive force is generated between the holding magnets. Thereby, it is possible to make it difficult to shift the relative position of the mobile phone 10 that is moving to the end of the assumed slide region.

  As described above, when the mobile phone 10 is in the closed state and in the most open state in the sliding direction, the movement in the sliding direction can be restricted by making the holding force work. In other words, when the first housing 12 and the second housing 14 are relatively moving in the sliding direction from the open state to the closed state, if the first housing 12 and the second housing 14 are moved to the closed state, they do not move any more. Can generate power. In addition, when the first housing 12 and the second housing 14 are relatively moved in the sliding direction from the closed state to the opened state, the first housing 12 and the second housing 14 are moved to the most opened state in the sliding direction. A force that does not move any further can be generated.

  In the above embodiment, four holding magnets are arranged on each long side, but the number and arrangement positions of the holding magnets are not limited to this. For example, one holding magnet is arranged in the first housing 12, and two holding magnets are provided at positions facing the holding magnets of the first housing 12 at both ends in the sliding direction of the second housing 14. It can also be set as the structure which has arrange | positioned the magnet.

  Moreover, it is preferable to use a magnet having a stronger holding force than the first magnet and the second magnet as the holding magnet. Thereby, the function as a stopper can be functioned more appropriately. A neodymium magnet can be used as the holding magnet.

  In addition, the mobile phone 10 can reduce the contact area between the first housing 12 and the second housing 14 during sliding by providing the protrusion 24. Thereby, the resistance during movement can be further reduced. In addition, by providing the protrusion 24, it is possible to suppress wear of other mechanisms such as the numeric keypad 18 provided on the back surface of the first housing 12 and the surface of the second housing 14.

  Here, the surfaces of the first housing 12 and the second housing 14, in particular, the surface of the protrusion 24 and / or the back surface of the first housing 12 are preferably formed of a material having excellent wear resistance. For example, it is preferable to use Duracon (registered trademark) resin or dry film resin. By forming the front surface of the protrusion 24 and / or the back surface of the first housing 12 with a material having excellent wear resistance, the durability of the mobile phone 10 with respect to the sliding operation can be improved and used for a longer period of time. It becomes possible. In the above embodiment, the protrusion is provided on the front surface of the second housing 14, but the protrusion may be provided on the back surface of the first housing 12. In addition, a protrusion may be provided on both the first housing 12 and the second housing 14.

  Note that although the mobile phone 10 can suppress the occurrence of wear, the protrusion is provided, but it is not always necessary. Even in the case where no protrusion is provided, it is preferable that the region where the generation of wear is to be reduced is recessed more than other portions. Thereby, it can suppress contacting with the housing | casing which faces.

  Moreover, it is preferable to ground each magnet, especially the first magnet and the second magnet. By grounding the magnet, the influence on other devices such as an antenna and a circuit can be reduced.

  Here, in the said embodiment, although the 1st magnet and the 2nd magnet were made into the rectangular shape, this invention is not limited to this. Hereinafter, an example of the first magnet and the second magnet that can be used in the present invention will be described with reference to FIGS. 5A to 7B illustrate only the outer shapes of the first housing 12 and the second housing 14 and the shapes of the first magnet and the second magnet for the sake of explanation. Each magnet is indicated by a solid line, and a state where magnetic poles are simply arranged is also indicated.

  First, FIG. 5-1 is a front view of a first housing including other magnets, and FIG. 5-2 is a front view of a second housing including other magnets. The first magnet 30a arranged in the first housing 12 shown in FIG. 5A has a shape in which the width in the short side direction varies depending on the position. Specifically, when the first magnet 30a moves along the sliding direction, the first magnet 30a gradually decreases in width from the middle, then becomes a constant width, then gradually increases in width, and then becomes a constant width. It is. That is, when the first magnet 30a moves in the sliding direction in terms of the number of magnetic poles, the number of magnetic poles gradually decreases from the state with the largest number of magnetic poles, the number of magnetic poles becomes constant, and then the magnetic poles Gradually increases, and the number of magnetic poles is the largest. On the other hand, the 2nd magnet 40a arrange | positioned at the 2nd housing | casing 14 shown to FIGS. 5-2 is the structure similar to the 2nd magnet 40. As shown in FIG.

  When the first magnet 30a shown in FIG. 5-1 and the second magnet 40a shown in FIG. 5-2 are used in combination, the mobile phone is in the closed state or the most open state, that is, any of the slide areas. In the case of such an end, the area where the first magnet 30a and the second magnet 40a overlap is increased. Further, when moving in the slide area, the area where the first magnet 30a and the second magnet 40a overlap is small. Thus, the attractive force generated between the first magnet 30a and the second magnet 40a can be changed by changing the region where the magnets overlap according to the position in the slide region. When moving in a certain area within the slide area, the movement in the slide direction can be made smoother, that is, the movement resistance can be reduced by reducing the attractive force.

  Next, FIG. 6-1 is a front view of a first housing including other magnets, and FIG. 6-2 is a front view of a second housing including other magnets. The first magnet 30b disposed in the first housing 12 illustrated in FIG. 6A has a trapezoidal shape in which the sides parallel to the short sides of the first housing 12 are parallel. More specifically, the width gradually increases as the receiver 22 moves from the end where the receiver 22 is disposed to the other end along the sliding direction. That is, when the first magnet 30b moves in the sliding direction in terms of the number of magnetic poles, the number of magnetic poles gradually increases from the state in which the end magnetic pole on the side where the receiver 22 is disposed is the smallest, The number of magnetic poles is the largest at the end of the. On the other hand, the second magnet 40b arranged in the second housing 14 shown in FIG. 6-2 has a trapezoidal shape in which the side having a large width is opposite to that of the first magnet 30b. More specifically, the width gradually increases as the receiver 22 moves from the end where the receiver 22 is disposed to the other end along the sliding direction. That is, when the second magnet 40b moves along the sliding direction from the end on the side where the numeric keypad 18 is not disposed, the number of the magnetic poles gradually decreases from the state with the largest number of magnetic poles. The number of magnetic poles is the smallest at the other end.

  When the first magnet 30b shown in FIG. 6-1 and the second magnet 40b shown in FIG. 6-2 are used in combination, the first magnet 30b and the second magnet 40b overlap when the mobile phone is in the closed state. When the area is the smallest and most open, the area where the first magnet 30b and the second magnet 40b overlap is the largest.

  Next, FIG. 7-1 is a front view of a first housing including another magnet, and FIG. 7-2 is a front view of a second housing including another magnet. The first magnet 30c disposed in the first housing 12 illustrated in FIG. 7-1 has a shape in which a half in the short direction of the first magnet 30a and a half in the short direction of the first magnet 30 are combined. . On the other hand, the second magnet 40c arranged in the second housing 14 shown in FIG. 7-2 is on the side corresponding to the portion on which the first magnet 30c is applied, and the numeric keypad 18 is arranged. It is a pentagonal shape with a corner on the side. More specifically, when the receiver 22 is moved from the end on the side where the receiver 22 is disposed along the slide direction, the width continues to be constant and the width becomes narrower from the middle. That is, in terms of the number of magnetic poles, when the second magnet 40c moves along the sliding direction from the end on the side where the numeric keypad 18 is not disposed, the state with the largest number of magnetic poles continues for a certain distance, and then gradually. The number of magnetic poles is reduced, and the number of magnetic poles is the smallest at the other end.

  By using the first magnet 30c shown in FIG. 7-1 in combination with the second magnet 40c shown in FIG. 7-2, when the mobile phone is at one end of the slide area, the first magnet 30c is used. And the area where the second magnet 40c overlaps increases. Further, when moving in the slide area, the area where the first magnet 30c and the second magnet 40c overlap is small. Thus, the attractive force which generate | occur | produces between the 1st magnet 30c and the 2nd magnet 40c can be changed because the area | region where a magnet overlaps changes according to the position in a slide area | region. When moving in a certain area within the slide area, the movement in the slide direction can be made smoother, that is, the movement resistance can be reduced by reducing the attractive force.

  Here, the shapes of the first magnet and the second magnet are preferably such that the relationship between the relative amount of movement between the first housing and the second housing and the area where the magnets overlap is as shown in FIG. Here, FIG. 8 is a graph showing the relationship between the area where the magnets overlap and the slide amount.

Here, the sliding amount is 0 when the first housing and the second housing are in the closed state, and the first housing and the second housing are in the most open state (sliding). The state most moved in the direction) is Max. In this way, when the slide amount is 0 or Max, the overlapping area is large, and when the slide amount is in the slide area, the overlap area is reduced to reduce the overlap area. The resistance acting between the casings during sliding can be reduced, and the resistance can be increased at the end of the sliding area. Accordingly, the slide can be easily stopped at the end portion of the slide area, and the slide can be easily performed in the middle of the slide area. Thereby, a user's operativity can be made high and it can make it easy to open and close. The overlapping area of the magnets is preferably the same area when the sliding amount is 0 and when it is Max. Thereby, the resistance which generate | occur | produces in closing operation and opening operation can be made comparable.

Further, the first casing 12a and the second casing 14a have a constant cross section perpendicular to the longitudinal direction as shown in FIG.

  As shown in FIG. 9, the first housing 12a and the second housing are formed by setting one of the facing surfaces of the first housing 12a and the second housing 14a as a concave portion and the other as a corresponding convex portion. The alignment with 14a can be made easier. Further, it is possible to prevent the magnetic poles facing the first magnet 30d and the second magnet 40d from shifting to the same pole during sliding.

  Moreover, when the surface where the 1st housing | casing and 2nd housing | casing oppose at the time of a slide is made into corresponding uneven | corrugated shape, it is preferable that the convex part and recessed part which face are made into a curved surface. FIG. 10 is a cross-sectional view showing a schematic configuration of another embodiment of the mobile phone. The first housing 12b shown in FIG. 10 has a recess formed on the back surface, and has a shape in which the central portion is recessed from the end portion in the lateral direction.

Yes. As described above, even if the first magnet 30f and the second magnet 40f are arranged in a state of being exposed from the casing, the first casing 12 and the second casing 14 are arranged in the same manner as when the first magnet 30f and the second magnet 40f are incorporated in the casing. Can be slid smoothly. Moreover, the 1st housing | casing 12 and the 2nd housing | casing 14 can also be attached or detached. Moreover, the distance between magnets can be shortened by exposing the 1st magnet 30f and the 2nd magnet 40f. Thereby, the attractive force generated between the first magnet 30f and the second magnet 40f can be further increased. Further, even when a permanent magnet having a weak magnetic force is used for the first magnet 30f and the second magnet 40f, the distance can be shortened, so that the attractive force can be increased. In addition, by using a permanent magnet having a weak magnetic force for the first magnet 30f and the second magnet 40f, it is possible to reduce the influence on other components of the mobile phone.

  Moreover, in the said embodiment, although all provided the 2nd magnet in the area | region in which the numeric keypad 18 (operation part 17) is not provided, this invention is not limited to this. Here, FIG. 12-1 is a front view of a first housing including another magnet, and FIG. 12-2 is a front view of a second housing including another magnet. The first housing 12 shown in FIG. 12A is provided with a first magnet 30h. The first magnet 30h has the same configuration as the first magnet 30 described above. On the other hand, the 2nd magnet 40h is arrange | positioned at the 2nd housing | casing 14 shown to FIGS. 12-2. The second magnet 40h has the same length in the longitudinal direction of the front as the first magnet 30h, and part of it overlaps the numeric keypad 18. Since the second magnet 40h can increase the attractive force, the second magnet 40h is preferably disposed closer to the first housing 12 when sliding than the numeric keypad 18. However, the second magnet 40h is disposed closer to the back surface of the second housing 14 than the numeric keypad 18. You may arrange in.

  As described above, by combining the first magnet 30h illustrated in FIG. 12A and the second magnet 40h illustrated in FIG. 12B, the design freedom of the first magnet and the second magnet can be further increased.

  Moreover, in the said embodiment, although the 1st magnet and the 2nd magnet were made into one shape extended in a longitudinal direction, you may divide | segment into plurality. In this case, it is preferable to arrange the first magnet and the second magnet so that a part of them faces each other in the slide region. The magnetic poles extending in the sliding direction are preferably the same magnetic pole. Accordingly, the mobile phone can be smoothly slid. In addition, it is necessary to provide one or more combinations of the S pole and the N pole in the short direction (direction perpendicular to the sliding direction), and it is preferable that the first magnet and the second magnet have three or more sets. By providing three or more combinations of S poles and N poles, movement in a direction orthogonal to the sliding direction can be appropriately suppressed.

  Moreover, you may divide | segment a 1st magnet and a 2nd magnet into plurality in a transversal direction. For example, the first magnet and the second magnet may be provided separately only in the vicinity of the long side of the housing, and the first magnet and the second magnet may not be provided in the central portion of the housing. When the first magnet and the second magnet are divided and provided, the magnetic pole at one end and the magnetic pole at the other end, that is, the magnetic pole at the end adjacent in the short direction, are the same magnetic pole. May be. That is, it is only necessary that at least one of the end faces parallel to the sliding direction is in contact with the south pole of the north poles of the first magnet and the second magnet. The same applies to the S pole.

When the first engagement element 82 and the second engagement element 84 are separated from each other in the thickness direction, the protrusions are in contact with each other and are not separated from each other.

  Thus, even when the engaging portion 80 that is a mechanical engaging mechanism is provided, the movement in the sliding direction can be restricted by the first magnet 30 and the second magnet 40. For this reason, the engaging portion 80 only needs to restrict the first housing 12c and the second housing 14c from being separated, and the design error of the engaging portion 80 can be further increased. Thereby, even when there is play in the engaging portion 80, the sliding operation can be performed smoothly. Further, when the engaging portion 80 is provided, it is only necessary that the first magnet 30 and the second magnet 40 can guide in the sliding direction. That is, the suction force can be made weaker than the suction force for preventing the first housing 12c and the second housing 14c from being separated. Thereby, the resistance during the sliding operation can be further reduced.
