Moreover, the upper housing | casing 20 and the lower housing | casing 30 are each formed vertically long.

  The upper housing 20 can slide along the superimposed surface with respect to the lower housing 30. As shown in FIG. 2, the slide is performed in the vertical direction (longitudinal direction of the overlapping surface (rectangle)) and in the direction in which the upper housing 20 rotates with respect to the lower housing 30 as shown in FIG. Is called. This slide is applied by a force applied by a user or the like, that is, by fixing one of the upper housing 20 and the lower housing 30 and applying a force in the sliding direction with respect to the other. Done. The slide mechanism will be described later.

  On the surface 20a opposite to the surface of the upper housing 20 that overlaps the lower housing 30 (hereinafter referred to as the surface 20a of the upper housing 20), the user's operation on the mobile terminal 10 and the status of the mobile terminal 10 A display unit 21 is provided for displaying an image corresponding to the above. Specifically, the display unit 21 is configured by an image display device such as a liquid crystal display, and displays an image controlled by a CPU (Central Processing Unit) or a memory included in the mobile terminal 10.

  An input unit 23 including a plurality of keys 22 is provided on the surface 20 a of the upper housing 20. When the user presses the key 22, the user can perform operations and inputs on the mobile terminal 10. As shown in FIGS. 2 and 3, the upper housing 20 slides upward on the surface of the lower housing 30 that overlaps the upper housing 20 (hereinafter referred to as the overlapping surface 30a of the lower housing 30). An input portion 32 composed of a plurality of numeric keys 31 for inputting a telephone number or the like is provided in a portion that is sometimes exposed. When the user presses the numeric key 31, the user can operate and input the mobile terminal 10.

  In addition, the upper casing 20 and the lower casing 30 (any one) are provided with a microphone, a speaker, and the like (not shown) for causing the mobile terminal 10 to function as a mobile phone. In addition, the mobile terminal 10 may be provided with functions such as a camera.

  Subsequently, a slide mechanism in the mobile terminal 10 will be described. FIG. 4A shows a surface 20b (hereinafter referred to as an overlapping surface 20b of the upper housing 20) that is superimposed on the lower housing 30 in the upper housing 20. FIG. 4B shows the overlapping surface 30 a of the lower housing 30. Grooves 24, 26, 27, 28 and a recess 25 are provided on the overlapping surface 20 b of the upper housing 20. Two protrusions 33 are provided on the overlapping surface 30 a of the lower housing 30. The groove portions 24, 26, 27, and 28 of the upper housing 20 are configured so that the protruding portions 33 of the lower housing 30 can be slidably accommodated. Moreover, the recessed part 25 becomes a structure which can support the protrusion part 33. FIG. The upper housing 20 can slide with respect to the lower housing 30 by sliding in the grooves 24, 26, 27, and 28 in which the protrusions 33 are accommodated. Below, the protrusion part 33, the groove parts 24, 26, 27, 28, and the recessed part 25 are demonstrated in detail.

  The two protrusions 33 are provided on the overlapping surface 30a of the lower housing 30 at a portion that is not exposed even when the upper housing 20 slides. Specifically, for example, as shown in FIG. 4B, the two projecting portions 33 are respectively provided in the vicinity of the upper side surface and in the vicinity of the left and right side surfaces on the overlapping surface 30 a of the lower housing 30. . As shown in FIG. 5, it is desirable that the protruding portion 33 has a wheel 34 that is a rotatable member at the tip thereof. This is because when the projecting portion 33 slides along the groove portions 24, 26, 27, and 28, the wheel 34 is rotated along the direction of the groove portions 24, 26, 27, and 28 and smoothly slides. The protrusion 33 does not need to be completely accommodated in the grooves 24, 26, 27, and 28, and can be slid along the grooves 24, 26, 27, and 28 as shown in FIG. The part may be accommodated.

  Of the groove portions 24, 26, 27 and 28, the two sliding groove portions 24 are for sliding the protruding portion 33 in the vertical direction. The two sliding grooves 24 extend in parallel in the vertical direction (sliding direction) at positions corresponding to the two protruding portions 33 in the left-right direction. In FIG. 4, the left protrusion 33a is accommodated in the right slide groove 24a (located on the left side when the upper housing 20 is turned over), and the right protrusion 33b is accommodated in the left slide groove 24b (upper housing). When the body 20 is turned over, it is housed in the right side).

  The upper end of the slide groove 24 corresponds to the position where the protrusion 33 is provided so that the upper housing 20 and the lower housing 30 are overlapped with each other as shown in FIG. It extends to the position to do. On the other hand, the lower end of the sliding groove 24 extends to a position corresponding to the length of sliding the upper housing 20 in the vertical direction. However, the length from the upper end to the lower end of the slide groove portion 24 is set to be equal to or longer than the length between the two projecting portions 33 because the slide for rotating the upper housing 20 is performed.

  The recess 25 is a portion that supports one protrusion 33 (in FIG. 4, the right protrusion 33b). Specifically, for example, as shown in FIG. 5, the recess 25 is formed as a hemispherical recess that is deeper than the grooves 24, 26, 27, and 28. As shown in FIG. 5B, the support of the protruding portion 33 b by the recess 25 serves as a central axis when the upper housing 20 is rotated and slid with respect to the lower housing 30. The recess 25 is provided on the outer side (left side) of the slide groove 24b that houses the protrusion 33b and in the vicinity of the lower end of the slide groove 24b. The recess 25 and the slide groove 24b are connected by a connecting groove 26. This is because the protruding portion 33b can slide between the slide groove 24b and the recess 25.

  Of the groove portions 24, 26, 27, 28, the rotation groove portion 27 is configured such that one protrusion portion 33 (the right-side protrusion portion 33 b in FIG. 4) is supported by the recess portion 25 and the other protrusion portion 33 ( In FIG. 4, the right protrusion 33a) is slid in an arc shape around the protrusion 33b. The rotation groove 27 is an arc-shaped groove having a central angle of 90 °, and the center of the arc is the recess 25 and the radius of the arc is the length between the two protrusions 33. The lower end 27a of the rotation groove 27 is provided on the inner side (left side) of the slide groove 24a that houses the protrusion 33a and in the vicinity of the lower end of the slide groove 24a. That is, the position of the recess 25 with respect to the slide groove 24b and the position of the lower end 27a of the rotation groove 27 with respect to the slide groove 24a have the same positional relationship. Further, the upper end 27b of the rotation groove 27 is located in the vicinity of the left surface. The rotation groove 27 intersects with the slide groove 24b.

  The vicinity of the lower end of the rotation groove 27 and the slide groove 24 a are connected by a connection groove 28. This is because the protrusion 33a can slide between the slide groove 24a and the rotation groove 27.

  A cable or the like for inputting / outputting electric power and signals between the upper housing 20 and the lower housing 30 may be provided along the above-described grooves 24, 26, 27, and 28.

  Subsequently, the sliding operation of the mobile terminal 10 according to the present embodiment will be described. First, the case where the upper housing | casing 20 is slid to an up-down direction with respect to the lower housing | casing 30 using FIG. 6 is shown. 6 is a view of the mobile terminal 10 as viewed from the lower housing 30 side (the viewpoint is reversed from that in FIG. 1).

  As shown in FIG. 6 (a), the upper housing 20 and the lower housing 30 are overlaid so that the overlapping surfaces 20b and 30a are aligned with each other, as shown by the arrows in the figure. A force is applied to the mobile terminal 10 so that 20 slides upward. When such a force is applied, each of the two protruding portions 33 slides downward along the two sliding groove portions 24 with respect to the sliding groove portion 24. The upper housing 20 slides upward with respect to the lower housing 30 in accordance with the sliding of the protrusion 33. As a result of the sliding of the upper housing 20 as described above, the lower surface of the overlapping surface 30a of the lower housing 30 is exposed as shown in FIG. 6B.

  Further, in the state shown in FIG. 6B, a force is applied to the mobile terminal 10 so that the upper housing 20 slides downward as indicated by an arrow in the figure. When such a force is applied, each of the two protruding portions 33 slides upward along the two sliding groove portions 24 with respect to the sliding groove portion 24. The upper housing 20 slides downward with respect to the lower housing 30 in accordance with the slide of the protrusion 33. As a result of the sliding of the upper housing 20 as described above, the state shown in FIG. Thus, the mobile terminal 10 according to the present embodiment can slide the upper housing 20 in the vertical direction with respect to the lower housing 30, and is a slide-type mobile terminal.

  Subsequently, when the upper housing 20 is slid to the left by 90 ° (as viewed from the upper housing 20 side) with respect to the lower housing 30 with reference to FIG. 7 (when the state shown in FIG. 3 is reached). ). 6 is a view of the mobile terminal 10 as seen from the lower housing 30 side (similar to FIG. 6).

  First, as shown in FIG. 7A, the lower part of the overlapping surface 30a of the lower housing 30 is exposed, and the protruding portion 33a is connected to the connecting groove portion 28 in the sliding groove portion 24a. With the protrusions 33b positioned at the portions of the slide groove 24b where the connecting groove 26 is connected, the upper housing 20 is positioned to the right (as viewed from the upper housing 20 side) as indicated by the arrows in the figure. Then, a force is applied to the mobile terminal 10 so as to slide leftward. When such a force is applied, the protrusion 33a slides through the connecting groove 28 and moves to the rotating groove 27 as shown in FIG. 7B. Further, the protrusion 33 b slides through the connecting groove 26 and moves to the recess 25. As a result, the upper housing 20 is slightly shifted to the right side (left side when viewed from the upper housing 20 side) with respect to the lower housing 30.

  Subsequently, in the state illustrated in FIG. 7B, the mobile phone 10 is moved so that the upper housing 20 rotates to the left (as viewed from the upper housing 20 side) as indicated by an arrow in the drawing. Apply force. When such a force is applied, the protrusion 33b is supported by the recess 25, and the protrusion 33a slides from the lower end 27a toward the upper end 27b in the rotation groove 27. As shown in FIG. 7C, the upper housing 20 is left with respect to the lower housing 30 around the position of the recess 25 (as viewed from the upper housing 20 side) according to the slide of the protrusion 33 a. Rotate to.

  When the protruding portion 33a reaches the upper end 27b by sliding in an arc shape with a central angle of 90 °, the upper housing 20 is 90 ° with respect to the lower housing 30 as shown in FIG. It will be in the state (state shown in FIG. 3) which rotated and was piled up sideways. Further, since the upper housing 20 is turned sideways, the display unit 21 of the upper housing 20 is also horizontally long with respect to the lower housing 30. Thus, the mobile terminal 10 according to the present embodiment can rotate the upper housing 20 with respect to the lower housing 30 and can change the display unit 21 from vertically long to horizontally long.

  In the mobile terminal 10 according to the above-described embodiment, the upper casing 20 is provided with the grooves 24, 26, 27, and 28 and the recess 25, and the lower casing 30 is provided with the protruding portion 33. It is good also as a structure which provides a protrusion part in a body and provides a groove part and a recessed part in a lower housing | casing. Such an upper housing 120 is shown in FIG. 8A, and the lower housing 130 is shown in FIG. 8B.

  FIG. 8 is a view showing the overlapping surfaces 120b and 130a as in FIG. The configuration is the same as that described above, except for the configuration of the protrusions, grooves, and recesses of the upper casing 120 and the lower casing 130. That is, the display unit 121 having the same configuration as described above is provided on the surface 120a of the upper housing 120.

  Two protrusions 122 are provided on the overlapping surface 120 b of the upper housing 120. Grooves 131, 133, 134, 135 and a recess 132 are provided on the overlapping surface 130 a of the lower housing 130. The groove portions 131, 133, 134, and 135 of the lower housing 130 are configured to be able to accommodate the protruding portion 122 of the upper housing 120 so as to be slidable. Moreover, the recessed part 132 becomes a structure which can support the protrusion part 122. FIG. The upper housing 120 can slide with respect to the lower housing 130 by sliding in the grooves 131, 133, 134, 135 in which the protrusions 122 are accommodated. Below, the protrusion part 122, the groove parts 131, 133, 134, 135, and the recessed part 132 are demonstrated in detail.

  The two protrusions 122 are provided on the overlapping surface 120b of the upper housing 120 at a portion that is not exposed even when the upper housing 120 slides. Specifically, for example, as shown in FIG. 8A, the two projecting portions 122 are provided in the overlapping surface 120 b of the upper housing 120, substantially in the vertical direction and near the left and right side surfaces, respectively. . In addition, since the length in which the upper housing 120 can be slid is determined according to the vertical position of the protruding portion 122, the vertical position of the protruding portion 122 is preferably determined based on the sliding length. .

  Of the grooves 131, 133, 134, and 135, the two sliding grooves 131 are for sliding the protrusion 122 in the vertical direction. The two slide grooves 131 extend in parallel in the vertical direction (slide direction) at positions corresponding to the two protrusions 122 in the left-right direction. In FIG. 8, the left protrusion 122a (positioned to the right when the upper housing 120 is turned over) is housed in the right slide groove 131a, and the right protrusion 122b (positioned to the left when the upper housing 120 is turned over). Is housed in the left slide groove 131b.

  The lower end of the slide groove 131 corresponds to the position where the protruding portion 122 is provided so that the upper housing 120 and the lower housing 130 are overlapped with each other as shown in FIG. It extends to the position to do. On the other hand, the upper end of the sliding groove 131 extends to a position corresponding to the length of sliding the upper housing 120 in the vertical direction. However, the length from the upper end to the lower end of the slide groove 131 is set to be equal to or longer than the length between the two protrusions 122 in order to perform the slide for rotating the upper housing 120.

  The recess 132 is a portion that supports one protrusion 122 (left protrusion 122a in FIG. 8). The configuration of the recess 132 is the same as the configuration of the recess 25 described above. The recess 132 is provided on the outer side (right side) of the slide groove 131a that houses the protrusion 122a and in the vicinity of the upper end of the slide groove 131a. The recess 132 and the slide groove 131 a are connected by a connection groove 133. This is because the protrusion 122a can slide between the slide groove 131a and the recess 132.

  Of the groove portions 131, 133, 134, and 135, the rotation groove portion 134 is configured such that one protrusion 122 (left protrusion 122 a in FIG. 8) is supported by the recess 132 and the other protrusion 122 ( In FIG. 8, the right protrusion 122b) is slid in a circular arc shape around the protrusion 122a. The rotation groove 134 is an arcuate groove having a central angle of 90 °, and the center of the arc is the recess 132 and the radius of the arc is the length between the two protrusions 122. The upper end 134a of the rotation groove 134 is provided on the inner side (right side) of the slide groove 131b that accommodates the protrusion 122b and in the vicinity of the upper end of the slide groove 131b. That is, the position of the recess 132 with respect to the slide groove 131a and the position of the upper end 134a of the rotation groove 134 with respect to the slide groove 131a have the same positional relationship. Further, the lower end 134b of the rotation groove 134 is located in the vicinity of the right side surface. The rotation groove 134 intersects with the slide groove 131a.

  The connection groove 135 connects the vicinity of the upper end of the rotation groove 134 and the slide groove 131b. This is because the protrusion 122b can slide between the slide groove 131b and the rotation groove 134.

  Subsequently, the sliding operation of the mobile terminal 110 constituted by the above-described upper casing 120 and lower casing 130 will be described. Since the slide in the vertical direction is the same as the above-described example, the description thereof is omitted. FIG. 9 shows a case where the upper housing 120 is slid to the left by 90 ° (as viewed from the upper housing 120 side) with respect to the lower housing 130 (when the state shown in FIG. 3 is reached). . FIG. 9 is a diagram of the mobile terminal 110 as viewed from the upper housing 120 side (opposite to FIGS. 6 and 7).

  First, as shown in FIG. 9A, the lower part of the overlapping surface 130a of the lower housing 130 is exposed, and the protruding part 122a is connected to the connecting groove part 133 in the sliding groove part 131a. Mobile terminal so that upper housing 120 slides to the right as shown by the arrow in the figure in a state where protrusion 122b is positioned at a portion where sliding groove 135 is connected to sliding groove 131b. A force is applied to 110. When such a force is applied, the protrusion 122a slides through the connecting groove 133 and moves to the recess 132 as shown in FIG. Further, the projecting portion 122 b slides through the connecting groove portion 135 and moves to the rotating groove portion 134. Thereby, the upper housing 120 is slightly shifted to the right with respect to the lower housing 130.

  Subsequently, in the state illustrated in FIG. 9B, a force is applied to the mobile terminal 110 so that the upper housing 120 rotates to the left as indicated by an arrow in the drawing. When such a force is applied, the protrusion 122a is supported by the recess 132, and the protrusion 122b slides from the upper end 134a toward the lower end 134b in the rotation groove 134. As shown in FIG. 9C, the upper housing 120 rotates to the left with respect to the lower housing 130 around the position of the recess 132 in accordance with the slide of the protrusion 122b. When the upper housing 120 is rotated, the protrusion 122 a supported by the recess 132 may also be rotated together with the upper housing 120. In that case, the protrusion 122a is fixed so as not to operate with respect to the upper housing 120. Further, the protrusion 122a supported by the recess 132 may not be rotated. In that case, the protrusion 122a is fixed to the upper housing 120 so as to be rotatable about an axis perpendicular to the overlapping surface 120b.

  When the projecting portion 122b reaches the lower end 134b by sliding in an arc shape with a central angle of 90 °, the upper housing 120 is 90 ° relative to the lower housing 130 as shown in FIG. It will be in the state (state shown in FIG. 3) which rotated and was piled up sideways. In addition, since the upper housing 120 is turned sideways, the display unit 121 of the upper housing 120 is also in a horizontally long state with respect to the lower housing 130. As described above, the mobile terminal 110 according to the present embodiment can rotate the upper housing 120 with respect to the lower housing 130 and can change the display unit 121 from vertically long to horizontally long.

  As described above, according to the mobile terminals 10 and 110 according to the present embodiment, the orientation of the display units 21 and 121 can be switched in the slide-type mobile terminal that slides in the vertical direction. For example, when the mobile terminals 10 and 110 are used as mobile phones, the display units 21 and 121 are used in a portrait orientation, and when the mobile terminals 10 and 110 are used as a television receiver using the one-segment service, display is performed. The parts 21 and 121 can be used in a landscape orientation.

  In addition, if a rotatable member such as a wheel 34 is provided at the tip of the projecting portions 33 and 122 as in the mobile terminals 10 and 110 in this embodiment, it can slide more smoothly. Thereby, it can be set as the portable terminals 10 and 110 which are easier to handle. Note that the rotatable member does not necessarily have to be a wheel. For example, as shown in FIG. 10, a spherical member 40 may be rotatably held by a bearing. Further, the protrusions 33 and 122 do not necessarily need to be provided with a rotatable member.

  Further, in the portable terminals 10 and 110 according to the above-described embodiments, the protrusions 33b and 122a are provided unless a force to be slid is applied to prevent the upper casings 20 and 120 from rotating unexpectedly. It is desirable to provide a configuration that prevents the material from moving to the recesses 25 and 132. Specifically, the protrusions 33b and 122a are formed on either one of the upper housings 20 and 120 and the lower housings 30 and 130 in the direction opposite to the direction from the sliding grooves 24b and 131a toward the recesses 25 and 132. It is preferable to provide an urging means for urging the casings 20 and 120. Specifically, for example, as shown in FIG. 11, the other casing 30 is urged toward the casing 20 provided with the recess 25 in the direction opposite to the direction in which the protruding portion 33 b faces the recess 25. Such a spring 50 is preferably provided.

  If such a spring 50 is provided, as shown in FIG. 11 (a), for example, even if the protruding portion 33b faces the concave portion 25 by a weak force such as the inclination of the mobile terminal 10, as shown in FIG. 11 (b). The lower housing 30 receives a force from the spring 50 and is rebounded as shown in FIG. Note that the spring 50 is preferably used to urge the protrusion 33b to be easily moved to the recess 25 when a force for sliding is applied. Thereby, when the force which is made to slide is not applied, it can prevent that the protrusion part 33b moves to the recessed part 25, and prevents that the upper housing | casing 20 and 120 rotate unexpectedly. Can do.
