Description

  The present invention relates to a case connecting mechanism capable of rotating another case relative to one case in a portable terminal device including two cases, and a portable terminal device including the case connecting mechanism.

  A display unit side housing having a display unit (hereinafter also referred to as a first housing or an R side housing) and an operation unit side housing having an operation unit (hereinafter also referred to as a second housing or an M side housing). ) With a rotary coupling mechanism, and there is a mobile phone that can rotate the R-side casing with respect to the M-side casing (see, for example, Patent Document 1). A user of such a mobile phone rotates the R-side casing when viewing one-segment broadcasting (one segment). Specifically, the length of the R-side casing in which the shape of the surface on which the display unit is provided is rectangular with respect to the long side of the M-side casing in which the shape of the surface on which the operation unit is provided is rectangular. The R-side casing is rotated so that the sides form an angle of 90 °. Hereinafter, a positional relationship in which the long side of the R-side housing forms an angle of 90 ° with respect to the long side of the M-side housing is expressed as “position rotated 90 °”. Further, the position before the R-side casing starts to rotate is expressed as “initial position” or “0 ° position”. When the R-side housing is in the initial position with respect to the M-side housing, the back surface of the R-side housing (the surface on which the display unit is not provided) covers the surface of the M-side housing.

  There is a mobile phone configured such that the R-side casing can be further rotated by 90 ° with respect to the M-side casing from a position rotated by 90 °. The state in which the R-side casing is set at a position rotated by 90 ° with respect to the M-side casing corresponds to the position rotated by 180 ° from the initial position. It is expressed as “position”. In general, when a user makes a call, the R-side casing is set to a “position rotated by 180 °”.

  A display unit side case and an operation unit side case are provided, and when the user performs an operation or a call, the display unit side case closes the operation unit side case, that is, from the closed state, the display side There is a foldable mobile phone that is set in an open state (see, for example, Patent Document 2). As described in Patent Document 2, in the case of a foldable mobile phone, in general, when it is opened, a display is provided so that the surface of the display unit side body and the surface of the operation unit side body are not parallel to each other. The rotation of the section side housing is restricted. This is because when the surface of the display unit side body and the surface of the operation unit side body reach in parallel, when the user performs an operation while viewing the screen of the display unit, the screen becomes difficult to see. That is, when the display unit side housing and the operation unit side housing are flat, the visibility is lowered. In addition, when the display unit side body and the operation unit side body are flat, the display unit side body or the operation unit side body is separated from the user's face, making it difficult to make a call.

  In a foldable mobile phone configured so that the display unit side case opens and closes with respect to the operation unit side case, the display unit side case and the operation unit side case do not become flat when opened. It is easy to make. This is because a structure that simply restricts the rotation of the display unit side body may be used.

Japanese Patent Laid-Open No. 2006-19925 International Publication No. 2003/47218 Pamphlet

  Even a mobile phone configured such that the display unit side body can be rotated to a position rotated by 90 ° relative to the operation unit side body, or can be rotated to a position rotated by 180 °, It is preferable that the display unit side case and the operation unit side case do not become flat when the position is rotated by ゜ or 180 °.

  Hereinafter, a mobile phone configured such that the display unit side body can be rotated to a position rotated by 90 ° with respect to the operation unit side body, or can be further rotated to a position rotated by 180 °. , “Mobile phone whose casing slides and rotates”, and a position rotated by 90 ° or a position rotated by 180 ° is expressed as “position after rotation”. A state in which the positional relationship between the two cases is “initial position (position of 0 °)”, “position rotated 90 °”, and “position rotated 180 °” may be referred to as three styles.

  As described above, in a mobile phone in which the housing slides and rotates, the display unit side housing and the operation unit side housing do not become flat when the display unit side housing is set to the rotated position. However, it is not easy to do so as compared to a foldable mobile phone.

  In a mobile phone in which the housing slides and rotates, the display unit side housing and the operation unit side housing do not become flat in the “90 ° rotated position” and the “180 ° rotated position”. In order to achieve this, it is conceivable that the rotary coupling mechanism is tilted and incorporated in the mobile phone.

  However, there is a possibility that a clearance (gap) between the display unit side body and the operation unit side body cannot be secured simply by tilting the rotation coupling mechanism and incorporating it into the mobile phone. That is, when the display unit side body is rotated, a part of the display unit side body may hit the operation unit side body and the rotation of the display unit side body may be hindered. In addition, when the rotation coupling mechanism is tilted and incorporated in the mobile phone, the height of the effective rotation coupling mechanism increases and the thickness of the mobile phone increases.

  Accordingly, the present invention provides a structure in which the first casing is rotated with respect to the second casing so that the first casing and the second casing do not become flat in the rotated state. It is an object of the present invention to provide a case coupling mechanism that can smoothly rotate the first case without increasing the number, and a portable terminal device including such a case coupling mechanism.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a front view showing a mobile phone as an example of a mobile terminal device provided with a case coupling mechanism according to the present invention. The mobile phone 1 according to the present invention can realize three styles. In FIG. 1, three styles are shown.

  As shown in FIG. 1, the mobile phone 1 includes a display unit side housing (first housing: R side housing) 10 and an operation unit side housing (second housing: M side housing) 20. ing. The R-side casing 10 and the M-side casing 20 are coupled by a casing coupling mechanism so that the R-side casing 10 can rotate with respect to the M-side casing 20. On the surface of the R-side casing 10, a display unit (not shown) such as an LCD is provided. An operation unit (key sheet) 21 is provided on the surface of the M-side housing 20.

  FIG. 1A shows a state where the R-side casing 10 is in the “initial position”. FIG. 1B shows a state in which the R-side casing 10 is in the “position rotated 90 °”. FIG. 1C shows a state in which the R-side casing 10 is in the “position rotated 180 °”.

  In general, the user sets the R-side casing 10 to a “position rotated by 90 °” when performing an operation or viewing 1Seg, and moves the R-side casing 10 when performing an operation or making a call. Set to “position rotated 180 °”.

  First, the housing rotation mechanism that is the premise of the present invention will be described. FIG. 2 is a perspective view illustrating an example of a housing rotation mechanism. FIG. 2A is a perspective view of the front surface of the housing rotation mechanism, and FIG. 2B is a perspective view of the back surface of the housing rotation mechanism.

  FIG. 3 is an exploded perspective view showing each part constituting the housing rotation mechanism. 3A is an exploded perspective view of the front surface of the housing rotation mechanism, and FIG. 3B is an exploded perspective view of the back surface of the housing rotation mechanism.

  2 and 3 includes a metal plate-like base plate 32 and a metal plate-like swing plate 31. A pin (not shown) connected to the R-side housing 10 is fitted into the through hole of the guide sleeve 36 attached to the swing plate 31. Therefore, the R-side housing 10 is fixed to the swing plate 31 via the pins and the guide sleeve 36. The base plate 32 is fixed to the M-side housing 20.

  Pins (swing pins) 34 and 35 are provided at both ends of the base plate 32. The swing pin 34 becomes a fulcrum of rotation when the swing plate 31 rotates from the “initial position” in the state shown in FIG. 2A in the direction of the arrow shown in FIG. Further, a flange 31 a is provided at the tip of the swing plate 31. The concave portion of the flange portion 31a is fitted into the swing pin 35 when the swing plate 31 is rotated 90 ° in the direction of the arrow. Accordingly, the rotation is stopped when the R-side casing 10 is rotated by 90 °. In other words, the swing pin 35 also serves as a restricting member that prevents the R-side housing 10 from rotating more than 90 °.

  As shown in FIG. 2B, a spring 41 is attached to the swing plate 31 via a collar portion of the guide sleeve 36 on the back side of the swing plate 31 with the base plate 32 interposed therebetween.

  As shown in FIGS. 2 and 3, the spring 41 is formed in a spiral shape. Then, one end of the spring 41 is stretched, and the stretched linear portion is fixed so as to wind around the guide sleeve 36. Therefore, the spring 41 applies a drag force to the swing plate 31 via the guide sleeve 36.

  Further, the other end of the spring 41 is extended, and the extended linear portion is fixed so as to be wound around the spring washer 42. The spring washer 42 is fixed to the base plate 32. Therefore, when the spring 41 moves, it moves using the spring washer 42 as a fulcrum.

  The base plate 32 is provided with a through portion 33. As shown in FIGS. 2 and 3, the penetrating portion 33 is formed in a substantially V shape. Further, the width of the penetrating portion 33 is smaller than the diameter (diameter) of the guide sleeve 36.

  When the swing plate 31 rotates from the “initial position” shown in FIG. 2A in the direction of the arrow (see FIG. 2A), the spring 41 resists in the direction opposite to the rotation direction. give. When a force in the rotational direction (the arrow direction shown in FIG. 2A) larger than the drag force is applied to the swing plate 31, the guide sleeve 36 moves along the through portion 33 as the swing plate 31 rotates. The rotational force applied to the swing plate 31 is applied from the R-side casing 10. A force is applied to the R-side casing 10 from a user who tries to rotate the R-side casing 10.

  FIG. 4 is a plan view showing the positional relationship between the base plate 32 and the swing plate 31. FIG. 4A shows the positional relationship between the base plate 32 and the swing plate 31 at the “initial position”. FIG. 4B shows the positional relationship between the base plate 32 and the swing plate 31 in the “state rotated by 90 °”. FIG. 4C shows the positional relationship between the base plate 32 and the swing plate 31 in the “state rotated 180 °”.

  As shown in FIG. 2A and FIG. 4A, in the “initial position”, the guide sleeve 36 is located at the uppermost part of the “\” portion (region 33a) in the V shape. With the swing pin 34 as a fulcrum, as the swing plate 31 rotates in the direction of the arrow (see FIG. 2 (A)), the guide sleeve 36 moves to the lower part of the portion of \ in the V shape. When the guide sleeve 36 passes through the merged portion of \ and / (region 33c) in the V shape, the spiral portion of the spring 41 moves toward the lower portion 33b of the V shape in the through portion 33, and the guide sleeve 36 is The region 33c is entered.

  The through portion 33 is formed such that the recess of the flange portion 31a is fitted into the swing pin 35 when the guide sleeve 36 contacts the lowermost portion of the lower portion 33b.

  The swing plate 31 is formed in a shape that is substantially symmetrical with respect to an axis that passes through the center of the guide sleeve 36. Therefore, the collar part 31b of the same shape as the collar part 31a is provided on the opposite side of the collar part 31a. In the state where the swing plate 31 is rotated by 90 °, as shown in FIG. 4B, the recess of the flange 31a is fitted into the swing pin 35, and the recess of the flange 31b is fitted into the swing pin 34. In addition, the recessed part of the collar part 31a can rotate around the swing pin 35, and the recessed part of the collar part 31b can rotate around the swing pin 34.

  A state in which the concave portion of the flange portion 31a fits into the swing pin 35, and a state in which the concave portion of the flange portion 31b fits into the swing pin 34, that is, a state in which the swing plate 31 is rotated by 90 ° (the R-side housing 10 is 90 °). In this state, when a force is applied to the short side portion 37 of the swing plate 31, the swing plate 31 tries to return to the “initial position” or the R-side casing 10 has rotated 180 °. Move to a state.

  When a force is applied to the short side portion 37 of the swing plate 31 closer to the swing pin 35, the swing plate 31 tries to return to the “initial position”.

  When a force is applied to the short side portion 37 of the swing plate 31 in the direction closer to the swing pin 34, the swing plate 31 is in a state in which the R-side housing 10 is rotated by 180 ° (even when the swing plate 31 is rotated by 180 °). Move to become. That is, the flange 31b is separated from the swing pin 34, and the swing plate 31 rotates with the swing pin 35 as a fulcrum. When the swing plate 31 is rotated so that the R-side casing 10 is rotated by 180 °, the spiral portion of the spring 41 and the guide sleeve 36 are the portion of the through portion 33 in the V shape (region 33c). Move towards the top of the.

  In the state in which the swing plate 31 is rotated 180 °, the guide sleeve 36 abuts on the uppermost part of the V-shaped portion as shown in FIG. 4C, and the spiral portion of the spring 41 extends from the through portion 33. Located in the detached part. 2A and 4A, the guide sleeve 36 abuts on the top of the V-shaped portion of the V-shape, and the spiral portion of the spring 41 extends from the through portion 33. Located in the detached part.

  When a force is applied to the long side portion 38 of the swing plate 31 in a state where the swing plate 31 is rotated 180 °, the swing plate 31 tries to return to the “state rotated 90 °”.

  By the mechanism of the housing rotation mechanism 30 as described above, the swing plate 31 is “initial position (position of 0 °)”, “position rotated 90 °” or “position rotated 180 °” with respect to the base plate 32. Can be. Since the R-side housing 10 is fixed to the swing plate 31 and the base plate 32 is fixed to the M-side housing 20, the R-side housing 10 is “initial position” and “90” with respect to the M-side housing 20. It can be in the state of “rotated position” or “position rotated 180 degrees”. That is, the mobile phone can be in any of three styles.

  FIG. 5 is a side view showing a cellular phone provided with a case coupling mechanism according to the present invention together with a folding cellular phone. As shown in FIG. 5A, in the foldable mobile phone, the display unit is not opened in parallel with the surface of the display unit side body 110 and the surface of the operation unit side body 120 when opened. The rotation of the side housing 110 is restricted.

  Further, as shown in FIG. 5B, in the cellular phone in which the casing slides and rotates, the surface of the display section side casing 210 and the operation section side casing after the display section casing 210 rotates. When the surface of 220 is parallel, the user's visibility with respect to the display unit is not good as compared with the case of the folding cellular phone shown in FIG.

  However, as shown in FIG. 5C, in the mobile phone in which the housing slides and rotates, the surface of the R-side housing (display-side housing) 10 in the state after the display-side housing 10 rotates. When the surface of the M-side housing (operation unit side housing) 20 is not parallel, the user's visibility with respect to the display unit does not decrease, as in the case shown in FIG. In the state where the surface of the R-side housing 10 and the surface of the M-side housing 20 are not parallel, specifically, the upper portion of the R-side housing 10 is inclined toward the viewer (user) side. State.

Embodiment 1. FIG.
Next, a case coupling mechanism using the case rotation mechanism 30 capable of realizing three styles in the mobile phone as shown in FIGS. 2 and 3 will be described.

  FIG. 6 is an exploded perspective view for explaining how to attach the housing rotation mechanism 30 to the mobile phone. As shown in FIG. 6, in the mobile phone, the case rotation mechanism 30 is attached between the R-side case 10 and the M-side case 20. Specifically, the swing plate 31 in the housing rotation mechanism 30 is fixed to the R-side housing 10, and the base plate 32 is fixed to the M-side housing 20.

  FIG. 7 is a side view for explaining how to attach the housing rotation mechanism 30 to the mobile phone. As shown in FIG. 7, the case rotation mechanism 30 is attached to the mobile phone at a predetermined angle with respect to the M-side case 20. In the present embodiment, the predetermined angle is 1.5 ° as an example.

  Further, “inclination by a predetermined angle (1.5 ° in this example)” specifically means that the surfaces of the base plate 32 and the swing plate 31 are inclined. More specifically, a straight line connecting the end 30a near the lower end (lower side in FIG. 7) of the mobile phone rotation mechanism 30 and the end 30b near the upper end (upper side in FIG. 7) is connected. In other words, the R-side housing 10 is inclined by 1.5 ° with respect to the longitudinal section of the M-side housing 20 (corresponding to the long axis 20a in the side view).

  In addition, R is attached to the back surface of the R-side housing 10 (the surface facing the M-side housing 20). That is, the side surface shape of the back surface of the R-side casing 10 is a point that is on a straight line perpendicular to the line segment at the midpoint of the line connecting the upper end and the lower end of the R-side casing 10 (R-side casing 10 It is an arc shape centered on a point far from the surface side. Therefore, the rear surface of the R-side housing 10 is curved so as to swell with respect to the M-side housing 20. The point where the center of the arc exists may be on a straight line passing through a point slightly shifted from the midpoint of the line segment connecting the upper end and the lower end of the R-side casing 10.

  Therefore, the curved surface from the central portion 10a toward the upper end (upper side in FIG. 7) of the R-side housing 10 is substantially the same as the curved surface from the central portion 10a toward the lower end (lower side in FIG. 7) of the R-side housing 10. is there. That is, the back surface of the R-side housing 10 is substantially bilaterally symmetrical with respect to the central portion 10a in the side view shown in FIG.

  The degree of bending is smaller in the vicinity of the central portion 10 a on the back surface of the R-side housing 10 than the upper and lower portions of the back surface of the R-side housing 10. That is, in the region including the central portion 10a, the difference in the left-right direction position (distance) according to the difference in the vertical position (distance difference) of the R-side casing 10 in the side view of FIG. The degree of difference is small. For example, assuming that the region including the central portion 10a (center region) on the back surface of the R-side housing 10 is flat, the upper and lower portions of the back surface of the R-side housing 10 are Each is inclined about 1.5 ° (for example, exactly 1.5 °) with respect to the central region of the back surface.

  Further, the same R as the R attached to the R-side housing 10 is attached to the surface of the M-side housing 20 (the surface facing the R-side housing 10). That is, it is curved so as to be recessed with respect to the R-side casing 10. Therefore, the shape of the back surface of the R-side housing 10 (shape when viewing the side view of FIG. 7) and the shape of the surface of the M-side housing 20 (shape when viewing the side view of FIG. 7) are the same. It is.

  FIG. 8 is a side view for more specifically explaining how to attach the housing rotation mechanism 30. As shown in FIG. 8, a recess 22 into which the base plate 32 of the housing rotation mechanism 30 is fitted is formed in the upper portion of the M-side housing 20 (in FIG. 8, the upper side in the longitudinal direction of the M-side housing 20). .

  FIG. 9 is an enlarged view showing an enlarged portion of the recess 22 in the M-side housing 20. In the example shown in FIGS. 8 and 9, the base plate 32 is supported by the surface of the rib inside the recess 22 (the portion shown in black in FIG. 9). Hereinafter, the surface of the rib (the portion shown in black in FIG. 9) is referred to as a support portion 23. However, in FIG. 9, reference numeral (23) is given only to a part of the support portion.

  The support portion 23 is inclined by 1.5 ° with respect to the long axis 20a of the M-side housing 20 (see FIG. 7). Specifically, when the plane formed by the support portion 23 (a plane including the support portion 23 which is the surface of the rib) is assumed and the support portion 23 is viewed from the side surface of the M-side housing 20, the support portion The support portion is formed so that the plane formed by 23 is inclined by 1.5 ° with respect to the straight line A (parallel to the long axis 20a) shown in FIG. 7 (like the straight line B shown in FIG. 7). 23 is formed.

  The rotation coupling mechanism is realized by the casing rotation mechanism 30 and the recess 22 formed in the M-side casing 20.

  Next, the positional relationship between the R-side casing 10 and the M-side casing 20 in the three styles of the mobile phone will be described with reference to FIG. FIG. 10A shows the positional relationship between the R-side casing 10 and the M-side casing 20 at the “initial position (0 ° position)”. FIG. 10B shows the positional relationship between the R-side casing 10 and the M-side casing 20 at the “position rotated 90 °”. FIG. 10C shows the positional relationship between the R-side casing 10 and the M-side casing 20 at the “position rotated 180 °”.

  In the “initial position”, the surface of the R-side casing 10 is in a state parallel to the long axis 20 a of the M-side casing 20. The housing rotation mechanism 30 is inclined by 1.5 ° with respect to the long axis 20 a of the M-side housing 20, so that the back surface of the R-side housing 10 is the length of the M-side housing 20 in the vicinity thereof. It is inclined with respect to the shaft 20a. That is, it is curved. However, the surface of the R-side housing 10 is parallel to the long axis 20 a of the M-side housing 20.

  In addition, a clearance is secured in the upper part of the R-side casing 10 and the M-side casing 20 so that the R-side casing 10 and the M-side casing 20 do not contact each other.

  When the lower portion of the R-side casing 10 is pushed to the rear side of the paper surface in FIG. 10 and rotated 90 ° from the “initial position”, the R-side casing 10 is moved to the “position rotated 90 ° shown in FIG. 10B. To reach. At the “position rotated by 90 °”, the surface of the R-side housing 10 is inclined by approximately 1.5 ° with respect to the long axis 20 a of the M-side housing 20.

  Further, since the same R is attached to the back surface of the R-side housing 10 and the front surface of the R-side housing 10, the R-side housing 10 and the M-side housing 20 are also in the “position rotated 90 °”. In the upper part, a clearance is secured so that the R-side casing 10 and the M-side casing 20 do not contact each other.

  When a downward force is applied from the “position rotated 90 °” to the right side of the R-side casing 10 at that position (the side close to the paper surface), the R-side casing 10 is shown in FIG. “Position rotated 180 °”. At the “position rotated by 180 °”, the surface of the R-side housing 10 is inclined by approximately 3.0 ° with respect to the long axis 20 a of the M-side housing 20.

  Further, since the same R is attached to the back surface of the R-side housing 10 and the front surface of the R-side housing 10, the R-side housing 10 and the M-side housing 20 are also in the “position rotated 180 °”. In the upper part, a clearance is secured so that the R-side casing 10 and the M-side casing 20 do not contact each other.

  FIG. 11 is an explanatory diagram for explaining the reason why the surface of the R-side casing 10 is inclined with respect to the long axis of the M-side casing 20 when the R-side casing 10 rotates with respect to the M-side casing 20. is there. FIG. 11 schematically shows the R-side casing 10, the M-side casing 20, and the casing rotation mechanism 30. FIG. 11A shows the positional relationship between the R-side casing 10 and the M-side casing 20 at the “initial position (position of 0 °)”. FIG. 11B shows the positional relationship between the R-side casing 10 and the M-side casing 20 at the “position rotated 90 °”. FIG. 11C shows the positional relationship between the R-side casing 10 and the M-side casing 20 at the “position rotated 180 °”.

  Further, on the left side of FIGS. 11A, 11B, and 11C, a schematic plan view showing the positional relationship between the R-side casing 10 and the M-side casing 20 is shown, and FIG. ), (B), and (C) are schematic side views showing the positional relationship between the R-side housing 10 and the M-side housing 20.

  As shown in FIGS. 11A, 11 </ b> B, and 11 </ b> C, the plane of the housing rotation mechanism 30 is inclined by 1.5 ° with respect to the long axis of the M-side housing 20. Since the base plate 32 in the housing rotation mechanism 30 is fixed to the M-side housing 20, the rotation axis of the R-side housing 10 is always set at 1. with respect to a straight line orthogonal to the long axis of the M-side housing 20. Tilt 5 °.

  As shown in FIG. 11A, at the “initial position”, the surface of the R-side casing 10 is parallel to the long axis of the M-side casing 20. Therefore, the display surface of the display unit 11 is not inclined with respect to the long axis of the M-side housing 20.

  As shown in FIG. 11B, at the “position rotated by 90 °”, the central region 12 on the back surface of the R-side casing 10 faces the M-side casing 20. As described above, the degree of curvature of the central region 12 is small compared to other regions. That is, it is almost flat. Then, the portion of the surface of the M-side housing 20 where the housing rotation mechanism 30 is attached, the center region 12 on the back surface of the R-side housing 10 and the surface of the R-side housing 10 are in a parallel state. Become close. The portion of the surface of the M-side housing 20 to which the housing rotation mechanism 30 is attached is inclined by approximately 1.5 ° with respect to the long axis of the M-side housing 20, so that the surface of the R-side housing 10 is also , It will tilt 1.5 °.

  As shown in FIG. 11C, the region 13 on the back surface of the R-side casing 10 faces the M-side casing 20 at the “position rotated 180 °”. As described above, the region 13 is inclined approximately 1.5 ° with respect to the surface of the R-side housing 10. Further, since the region 13 is substantially parallel to the surface of the M-side housing 20, the region 13 is already inclined by 1.5 ° with respect to the long axis of the M-side housing 20. Therefore, the surface of the R-side casing 10 is inclined by approximately 3.0 ° with respect to the long axis of the M-side casing 20.

  As described above, in the mobile phone capable of realizing the three styles, the surface of the display unit is tilted with respect to the M-side housing 20 when performing operations, talking, or watching 1Seg. be able to. Specifically, when the case rotation mechanism 30 is inclined by 1.5 ° with respect to the long axis of the M-side case 20, the surface of the display unit is almost 1 in the “position rotated 90 °”. Tilt 5 °. Further, at the “position rotated 180 °”, when the slope of the region 13 on the back surface of the R-side housing 10 with respect to the long axis of the M-side housing 20 is 1.5 °, the surface of the display portion is almost The inclination is 3.0 ° (the sum of the inclination at the “position rotated 90 °” and the inclination of the region 13 on the back surface of the R-side casing 10).

  In addition, the outer shapes of the R-side housing 10 and the M-side housing 20 are shaped so that a clearance can be secured so that the R-side housing 10 and the M-side housing 20 do not come into contact in any of the three styles. Therefore, when the surface of the display unit is inclined with respect to the M-side casing 20, the rotation of the R-side casing 10 is not hindered.

  In the present embodiment, the display unit can be tilted like a general folding mobile phone, and the user can easily see the screen. Moreover, it becomes possible to prevent the increase in apparatus thickness by making the opposing surface of the R side housing | casing 10 and the M side housing | casing 20 into R shape, and design property and goods can be improved.

  In the first embodiment, an example in which the case rotation mechanism 30 is tilted by 1.5 ° and incorporated in a mobile phone has been described. However, “1.5 °” is an example, and the degree of tilt is 1.5. It may be other than ゜.

  FIG. 12 is a side view showing a comparative example of how to attach the housing rotation mechanism 30 to the mobile phone. Unlike the case of the present embodiment shown in FIG. 7, in the comparative example shown in FIG. 12, the back surface of the R-side housing 210 and the front surface of the M-side housing 220 are on the long axis 20 a of the M-side housing 220. They are parallel and flat. Using such R-side casing 210 and M-side casing 220, the casing rotation mechanism 30 is tilted by a predetermined angle (as an example, 1.5 °) with respect to the long axis 20a of the M-side casing 220. Assume that it is attached to a mobile phone.

  FIG. 13 is a side view showing the positional relationship between the R-side casing 210 and the M-side casing 220 in the three styles of the mobile phone in the comparative example shown in FIG. As shown in FIG. 13A, the clearance at the top of the R-side casing 210 and the M-side casing 220 is the same as the clearance at the bottom of the R-side casing 210 and the M-side casing 220.

  As shown in FIG. 13A, at the “initial position”, the front surface of the R-side housing 10 and the back surface of the M-side housing 20 are parallel to each other.

  When the R-side casing 10 rotates 90 ° from the “initial position”, the R-side casing 10 reaches the “position rotated 90 °” shown in FIG. At the “position rotated by 90 °”, the surface of the R-side housing 10 is inclined by 1.5 ° with respect to the long axis 20 a of the M-side housing 20. In this state, as shown in FIG. 13B, the clearance is secured at the upper part, but the clearance margin becomes smaller at the lower part.

  Then, as shown in FIG. 13C, at the “position rotated 180 °”, the clearance margin is further reduced in the lower part. FIG. 13C shows an example in which the clearance is not secured. That is, an example is shown in which the R-side casing 10 cannot actually reach the “position rotated 180 °”.

  In order to ensure the clearance even at the “position rotated 180 °”, the height of the casing rotation mechanism 30 is increased (the casing rotation mechanism 30 is thickened), and the clearance at the “initial position” ( It is necessary to increase the gap). In that case, the thickness of the mobile phone becomes large.

In other words, by adopting the same curved shape, the clearance between the R-side housing 10 and the M-side housing 20 at the “position rotated 90 °” and “position rotated 180 °” is secured. However, the clearance may be secured by another shape of the R-side housing 10 and the M-side housing 20.

FIG. 15B shows the positional relationship between the R-side casing 15 and the M-side casing 25 at the “position rotated 90 °”. FIG. 15C shows the positional relationship between the R-side casing 15 and the M-side casing 25 at the “position rotated 180 °”.

  Unlike the comparative example shown in FIG. 12, in the second embodiment shown in FIGS. 14 and 15, the back surface of the R-side housing 15 and the surface of the M-side housing 25 are flat. However, it is inclined with respect to the long axis 20a of the M-side housing 25 by a predetermined angle (as an example, 1.5 °). The predetermined angle is the same as the angle at which the casing rotation mechanism 30 is inclined.

  Since the M-side casing 25 is formed so that the width (thickness) is narrowed toward the lower part, when the R-side casing 15 rotates from the “initial position” to the “position rotated 90 °”. In addition, the clearance between the R-side casing 15 and the M-side casing 25 is ensured even when rotating from the “position rotated 90 °” to the “position rotated 180 °”. That is, the rotation of the R-side casing 15 is not obstructed by the M-side casing 25 and cannot reach the “position rotated 180 °”.

Specifically, it is inclined at a predetermined angle (as an example, 1.5 °) with respect to the long axis 20a of the M-side casing 26. The predetermined angle is the same as the angle at which the casing rotation mechanism 30 is inclined. The central plane is a plane parallel to the long axis 20 a of the M-side casing 26. The lower plane (the plane farthest from the mounting portion of the casing rotation mechanism 30) is a plane that reduces the width (thickness) of the R-side casing 16 toward the lower portion of the R-side casing 16.
