Refers to the direction of the body's center of rotation.
On the other hand, a 1st rotation member and a 2nd rotation member are members as a spindle for a 2nd housing | casing to rotate with respect to a 1st housing | casing, The 2nd housing | casing with respect to a 1st housing | casing is a member. With the rotation, the first rotating member or the second rotating member rotates around the axis.

  According to this configuration, the second casing is opened with respect to the first casing around the first rotation axis of the connecting portion, and the second casing is moved around the second rotation axis. When opened, it becomes a side-open state. When performing the lateral opening, the first engagement portion provided on the upper surface of the first housing and the second engagement provided at a position corresponding to the first engagement portion on the surface of the second housing. By engaging the joint portion, the second rotation shaft is fixed along the longitudinal direction of the first housing, and it is possible to perform lateral opening. At this time, the second housing portion provided with the magnet of the second engagement portion attracts the engagement pin formed of a magnetic body by a magnetic force to cause the engagement pin to protrude from the surface of the first housing, and the second By rotating the casing around the second rotation axis, the second protrusion is accommodated in the second accommodating portion and the engagement pin is locked. In addition, since the second projecting portion is rotatable about the axis of the first projecting portion, the engagement pin does not sufficiently project in the transition state between the open state and the closed state, In an insufficiently engaged state, such as when the protrusion is not in a predetermined position, the second protrusion is applied when an external force is applied that causes the second housing to move relative to the first housing. Is pivoted about the axis of the first projecting portion along the inclined surface of the second housing portion in a state of being housed in the second housing portion, and is disengaged from the second housing portion. It is possible to prevent damage around the second engaging portion in the housing.

  The portable terminal of the present invention is characterized in that the first engaging portion is formed integrally with the first protruding portion and the second protruding portion.

  According to this structure, since the 1st protrusion part and the 2nd protrusion part are integrally formed, the structure of an engagement pin can be simplified.

  Furthermore, the portable terminal of the present invention includes a holding portion that holds the first engaging portion inside the first housing, and the second housing rotates around the first rotation shaft. In the opened state, a concave portion for accommodating the second protruding portion is formed on the top surface of the holding portion so that the first engaging portion does not protrude from the display portion surface, and the concave portion guides the second protruding portion. It is characterized in that a slope is formed.

  According to this configuration, in the state where the second casing is rotated around the first rotation axis and opened, the second protrusion is accommodated in the recess formed on the top surface of the holding unit while being guided by the inclination. Therefore, the pivotable engagement pin can be securely stored.

  Furthermore, in the portable terminal of the present invention, the inclined surface of the second housing portion is an edge portion on the first housing portion side, and is provided on the side end surface side of the second housing. Features.

The connecting portion 13 includes a connecting portion main body 13 </ b> A, a first rotating member 33 (see also FIG. 6), and a second rotating member 34.
The first rotating member 33 is a support member for connecting the lower housing 11 and the connecting portion main body 13 </ b> A and for rotating the connecting portion main body 13 </ b> A relative to the lower housing 11.
The first rotating member 33 is arranged along the first rotating shaft 31 described above, and is orthogonal to the thickness direction of the lower casing 11, and the short side direction (width) of the lower casing 11. Direction).

The second rotating member 34 connects the upper housing 12 and the connecting portion main body 13A, and serves as a support shaft for rotating the upper housing 12 with respect to the lower housing 11 and the connecting portion main body 13A. It is said that.
The axis of the second rotating member 34 is arranged along the second rotating shaft 32 described above, and is orthogonal to the thickness direction of the upper casing 12, and the long side direction (longitudinal direction) of the upper casing 12. Direction).
One end portion of the second rotating member 34 is connected to the connecting portion main body 13 </ b> A and the other end portion is connected to the upper housing 12. Therefore, the upper housing 12 is cantilevered by the second rotating member 34.

Here, the first rotation shaft 31 and the second rotation shaft 32 are the rotation centers of the lower housing 11 and the upper housing 12 when the mobile terminal 10 shifts from the closed state to the vertical open state or the horizontal open state. Refers to the direction of the line.
Specifically, the first rotation shaft 31 is perpendicular to the thickness direction of the lower housing 11 and is along the short side direction (width direction) of the lower housing 11. The second rotation shaft 32 is orthogonal to the thickness direction of the upper housing 12 and is along the long side direction (longitudinal direction) of the upper housing 12. The first rotation shaft 31 and the second rotation shaft 32 are orthogonal to each other.

In the present invention, the first rotating member 33 and the second rotating member 34 rotate the upper housing 12 and the connecting portion 13 with respect to the lower housing 11 or the upper housing with respect to the lower housing 11 and the connecting portion 13. As the body 12 rotates, the first rotating member 33 or the second rotating member 34 rotates about the axis.
In addition, the state in which the upper housing 12 rotates about the second rotation shaft 32 with respect to the lower housing 11 refers to the period from the closed state to the complete laterally open state. However, the sandwiching angle between the lower housing 11 and the upper housing 12 while the upper housing 12 is rotating is not limited.

  Further, in the present embodiment, strictly speaking, when the portable terminal 10 changes from the closed state to the vertically opened state, the upper casing 12 and the connecting portion 13 rotate integrally with respect to the lower casing 11, and the portable terminal 10 It should be explained that the upper housing 12 rotates with respect to the lower housing 11 and the connecting portion 13 when the state 10 is changed from the closed state to the laterally opened state. Is simply described as the upper housing 12 rotating relative to the lower housing 11, and the description of the connecting portion 13 may be simplified.

The first engagement means 15 is provided between the mobile terminal 10 starting from the closed state and starting from the side-open state until the complete side-open state is obtained, and from the side-open state to returning to the closed state. By engaging the longitudinal ends 37 of the body 11 and the longitudinal ends 38 of the upper housing 12, that is, the opposite ends of the lower housing 11 and the upper housing 12 from the connecting portion 13, This is means for assisting the second rotating member 34 that cantilever-supports the upper housing 12.
Even when an external force is applied to the mobile terminal 10 in the closed state, the state between the closed state and the laterally opened state, or in the completely laterally opened state by the first engagement means 15, The load is not concentrated on specific parts of the connecting portion 13, the second rotating member 34, and the like, and there is an effect that there is less fear of breakage.

Based on FIGS. 5-15, the structure of the 1st engaging means 15 is demonstrated.
FIG. 5 is an exploded perspective view of the lower housing 11 and the upper housing 12 when the mobile terminal 10 is closed. In FIG. 5, the first engagement means 15 includes an engagement pin 45 that is a first engagement portion provided at the longitudinal end portion 37 of the lower housing 11, and the engagement pin 45 on the lower housing 11. A holding portion 49 to be held, a stopper 50 for preventing the engagement pin 45 from coming out of the holding portion 49, a second engaging portion 46 provided at the longitudinal end portion 38 of the upper housing 12, and a lower housing 11 is provided with a lower casing magnet (magnet) 48 provided in the apparatus 11.

As shown in FIG. 9, the engagement pin 45 is connected to the first protrusion 51 and the first protrusion 51 that protrude along the thickness direction of the lower housing 11 from the surface provided with the operation portion 23. A substantially cylindrical second protrusion 52 extending in a direction intersecting the continuous direction of the first protrusion 51. Therefore, the engagement pin 45 has a shape in which the first protrusion 51 and the second protrusion 52 are integrally connected in a substantially L shape. Further, the engagement pin 45 can be rotated by a predetermined angle (18 degrees to the left and right) around the axis of the first protrusion 51.
The engagement pin 45 is formed of a magnetic material, and the tip (open end) of the second protrusion 52 faces the side opposite to the connecting portion 13, that is, the longitudinal direction end 37 of the lower housing 11. The second projecting portion 52 can project from the lower housing 11 to a position along the second rotation shaft 32.

The holding portion 49 is housed and fixed inside the lower housing 11, and is inserted through the first protruding portion 51 of the engagement pin 45. Since the engagement pin 45 is rotatably held by a predetermined angle as described above, the first projecting portion 51 can have a circular cross section, and a stopper can be provided so that the engagement pin 45 can be rotated by a predetermined angle. Or the 1st protrusion part 51 can be made into a rectangular cross section, and the shape of the hole which supports the 1st protrusion part 51 in a holding | maintenance part can also be made into the circular cross section which can rotate a rectangular cross section by a predetermined angle.
Note that the engagement pin 45 is preferably rotated so that the tip of the second projecting portion 52 approaches the operating portion 23.

  According to this configuration, when an external force that rotates the engaging pin 45 is applied, the direction opposite to the side where the second projecting portion 52 is locked by the second engaging portion 46 (that is, the second accommodating portion 56 side). Therefore, the engagement pin 45 is easily detached from the second engagement portion 46.

  As shown in FIGS. 13A to 13C, in the state where the upper housing 12 is rotated about the first rotation shaft 31 and opened (that is, in the vertically opened state), It is desirable to provide the recessed part 49E which accommodates so that the 2 protrusion part 52 may not protrude, and to provide the concave seating surface 49E which rests the 2nd protrusion part 52 in the bottom part of the recessed part 49E. The inner side of the recess 49E is an inclined surface 49G that guides the second protrusion 52 toward the bottom.

  Thus, when the upper housing 12 rotates about the first rotation shaft 31, the engagement pin 45 is not engaged with the second engagement portion 46, so that the engagement pin 45 is accommodated in the recess 49E. Thus, the engagement pin 45 is prevented from protruding from the surface 11A of the lower housing 11. At this time, the rest surface 49F is provided at the bottom of the recess 49E, and the inclined surface 49G for guiding the second protrusion 52 is provided on the inner surface of the recess 49E, so that the rotatable second protrusion 52 can be reliably accommodated.

As shown in FIG. 9, the engagement pin 45 is inserted into the holding portion 49 and is a base end portion of the first protruding portion 51, that is, a connection portion with the second protruding portion 52 in the first protruding portion 51. A stopper 50 is provided at the opposite end. The stopper 50 has a metallic cylindrical shape, and is inserted into and fixed to the proximal end portion of the first protruding portion 51.
The stopper 50 may be a non-magnetic material other than metal as long as the engagement pin 45 is a magnetic material.

Such an engagement pin 45 is in a range from a position where the second protrusion 52 contacts the resting surface 49F of the upper surface 49A of the holding portion 49 to a position where the stopper 50 contacts the lower surface 49B of the holding portion 49. It can slide with respect to the holding portion 49 along the axial direction of the one protruding portion 51.
When the second protrusion 52 is in a position where the engagement pin 45 is in contact with the upper surface 49 </ b> A of the holding part 49, the top of the first protrusion 51 and the second protrusion 52 are separated from the surface 11 </ b> A of the lower housing 11. When the stopper 50 is in a position where it does not protrude and contacts the lower surface 49 </ b> B of the holding part 49, the axis of the second protrusion 52 is arranged along the second rotation shaft 32.

  The lower housing magnet 48 is disposed directly below the engagement pin 45 along the axial direction of the first protrusion 51 inside the lower housing 11. As shown in FIG. 10A, when the lower casing magnet 48 is in a position where the second protrusion 52 contacts the upper surface 49A of the holding section 49, that is, the engaging pin 45 is accommodated in the lower casing 11. When it is, it is arranged at a position where it does not contact the stopper 50 via the interval S1.

  Since such a lower casing magnet 48 has a sheet metal 48A laminated on its surface, the magnetic force of the lower casing magnet 48 with respect to the engagement pin 45 can be selected by appropriately selecting the material, thickness, area, etc. of the sheet metal 48A. Can be set arbitrarily.

When the mobile terminal 10 is in the closed state, the second engagement portion 46 is the first of the engagement pins 45 protruding from the lower housing 11 at a position facing the engagement pin 45 that is the first engagement portion described above. A first accommodating portion 55 (see FIGS. 5, 6, and 9) into which the first protruding portion 51 can be inserted, and a second accommodating portion into which the second protruding portion 52 of the engagement pin 45 protruding from the lower housing 11 is inserted. 56 (see FIGS. 5, 6, and 10).
In the second engaging portion 46, the first housing portion 55 and the second housing portion 56 are arranged along the longitudinal direction of the upper housing 12, and the first housing portion 55 is disposed at a position close to the connecting portion 13. .

As shown in FIGS. 8 and 9, the first accommodating portion 55 is a block body having a substantially rectangular opening 58 </ b> A and a substantially V-shaped opening 58 </ b> B by a fan-shaped hollow portion 55 </ b> B having a predetermined thickness. An opening 58A is provided along the surface 12A of the upper housing 12 (see FIG. 6).
The shaft portion 59 formed on the side opposite to the opening 58B is disposed such that the axis passes through the arc center of the opening 58B. The inner surface 58 of the lightening part 55B is a smooth surface.

In the first housing 55, an upper casing magnet (magnet) 63 is embedded by insert molding around the thinned portion 55B, and an arcuate guide groove 55A is formed around the opening. As the upper casing magnet 63, a magnet having a larger magnetic force than the above-described lower casing magnet 48 is employed. The guide groove 55 </ b> A is disposed so that the center of the arc is along the axis of the shaft portion 59. Such a first accommodating portion 55 is arranged so that the axis of the shaft portion 59 is along the second rotation shaft 32, and by a return spring 47 that is a torsion spring that is passed through the shaft portion 59,
The opening 58 </ b> A is always maintained along the surface 12 </ b> A of the upper housing 12.

As shown in FIGS. 7, 8, and 10, the second storage portion 56 has a block shape having a substantially rectangular opening 56 </ b> C and a substantially U-shaped opening 56 </ b> D by a substantially U-shaped thinning portion 56 </ b> B. A projection 56A is provided around the opening 56D. The protrusion 56 </ b> A is inserted into the guide groove 55 </ b> A of the first housing portion 55.
The second housing portion 56 is disposed adjacent to the first housing portion 55, and is fixed to the upper housing 12 so that the opening 56 </ b> C is along the surface 12 </ b> A of the upper housing 12.

  Since the second engaging portion 46 as described above is maintained by the return spring 47 so that the opening 58A of the first housing portion 55 is along the surface 12A of the upper housing 12, the opening of the first housing portion 55 is usually provided. 58A and the opening 56C of the second housing portion 56 are oriented so as to be continuous along the surface 12A of the upper housing 12.

As shown in FIGS. 14A, 14B, and 7B, it is an opening edge portion on the first housing portion 55 side in the second housing portion 56 and the side end face side of the upper housing 12 It is desirable to provide the inclined surface 56E.
Accordingly, when the engagement pin 45 and the second engagement portion 46 are not properly engaged, the second accommodation portion 56 that accommodates the second protrusion 52 of the engagement pin 45 is provided. It can come off from the 2nd accommodating part 56 along the inclined surface 56E. The angle of the inclined surface 56E is not limited.

  As shown in FIGS. 14 and 15, the inclined surface 56 </ b> E desirably starts from a position corresponding to the start position 52 </ b> B of the hemispherical portion 52 </ b> A at the tip of the second protrusion 52. As a result, if the amount of protrusion of the second protrusion 52 is insufficient, the hemispherical portion 52A is immediately applied to the inclined surface 56E, so that the second protrusion 52 is disengaged from the second accommodating portion 56.

The second engaging means 16 is configured so that the upper housing 12 does not rotate about the second rotation shaft 32 when the mobile terminal 10 is in the closed state and the vertically opened state. This is means for restricting the rotation of the housing 12.
The second engagement means 16 prevents the upper housing 12 from rotating about the second rotation shaft 32 unintentionally by the user when the mobile terminal 10 is in the closed state and the vertically open state. There is an effect that it is possible to prevent the load from being concentrated and damaged at specific parts of the housing 12, the connecting portion 13, the second rotating member 34, and the like.

Returning to FIGS. 3 to 4, the configuration of the second engaging means 16 will be described.
The second engaging means 16 includes an engaging portion 66 provided on the short side surface 12C of the upper housing 12 connected to the connecting portion main body 13A of the connecting portion 13, and the short side surface 12B of the connecting portion main body 13A. And an engaging portion 67 that is provided on the end face 13B facing the engaging portion 66 and is engaged with the engaging portion 66.
These engaging portions 66 and 67 are arranged on the opposite side in the width direction with respect to the position where the second rotating member 34 is arranged.

  The engaging portion 66 includes a lock pin 66A that can project and retract from the short side surface 12B of the upper housing 12 toward the end surface 13B of the connecting portion main body 13A, and a lock pin 66A attached to the end surface 13B of the connecting portion main body 13A. A return spring 69 is provided, and a lock button 66C for accommodating the lock pin 66A in the upper housing 12 while compressing the return spring 69. The lock pin 66 </ b> A is held by the return spring 69 so as to protrude from the short side surface 12 </ b> B of the upper housing 12.

Such an engaging portion 66 is such that the user presses the lock button 66C provided on the side portion 12A of the upper housing 12 in the direction of arrow AB (see FIG. 3B, the longitudinal direction of the upper housing 12). The lock pin 66A can be accommodated in the upper housing 12 by being slid along.
The engagement portion 67 is an engagement hole that can accommodate the tip of the lock pin 66A (see FIGS. 3A and 4).

In the second engaging means 16 as described above, the rotation of the upper housing 12 with respect to the connecting portion main body 13A of the connecting portion 13 is restricted in a state where the tip of the lock pin 66A is engaged with the engaging portion 67. The
Accordingly, in the closed state and the vertically open state, the mobile terminal 10 is not intended to be rotated by the user and the upper housing 12 does not rotate about the second rotation shaft 32, thereby the upper housing 12 and the connecting portion. 13. The load does not concentrate on a specific part of the second rotating member 34 or the like and is not damaged.

  Then, when the user changes the portable terminal 10 from the closed state to the laterally open state, the second rotation is performed after the user releases the engaged state of the engaging portions 66 and 67 by operating the lock button 66C. The upper housing 12 is manually rotated with respect to the connecting portion main body 13A of the connecting portion 13 around the shaft 32.

  When the user changes the portable terminal 10 from the laterally open state to the closed state, the upper casing 12 is manually rotated with respect to the connecting portion main body 13A of the connecting portion 13 around the second rotating shaft 32. Then, after the lock pin 66A, whose tip is in contact with the engaging portion 67, is temporarily accommodated in the upper housing 12 while compressing the return spring 69, the lock pin 66A is again lifted along with the extension of the return spring 69. It protrudes from the housing 12 and engages with the engaging portion 67, whereby the rotation of the upper housing 12 with respect to the connecting portion main body 13A of the connecting portion 13 is restricted again.

Next, the operation of the mobile terminal 10 of this embodiment will be described.
When the portable terminal 10 is in a closed state, that is, when the lower housing 11 and the upper housing 12 are in a state of overlapping each other, the first protrusion of the engagement pin 45 that is the first engagement portion of the first engagement means 15 The top part of the part 51 and the second projecting part 52 face each other, and the first housing part 55 and the second housing part 56 of the second engaging part 46 face each other.

At this time, since the influence of the magnetic force of the upper housing magnet 63 on the engaging pin 45 is larger than the influence of the magnetic force of the lower housing magnet 48, the engaging pin 45 of the lower housing 11 is caused by the magnetic force of the upper housing magnet 63. It is pulled out from the surface 11A and reliably protrudes, and the top of the first protrusion 51 and the second protrusion 52 are inserted into the first storage part 55 and the second storage part 56 from the openings 58A and 56C.
At this time, since the opening 58 </ b> A of the first housing portion 55 and the opening 56 </ b> C of the second housing portion 56 are continuous along the surface 12 </ b> A of the upper housing 12 by the return spring 47, The top portion of the first projecting portion 51 and the second projecting portion 52 are smoothly inserted into the housing portion 56.

As shown in FIG. 12A, in the mobile terminal 10, in the closed state, the engagement pin 45 that is the first engagement portion is connected to the first accommodation portion 55 and the second accommodation portion 56 of the second engagement portion 46. Although inserted, both the opening 58A of the first housing portion 55 and the opening 56C of the second housing portion 56 face the surface 11A of the lower housing 11, so that the engagement pin 45 is connected to the first housing portion 55 and It is detachable with respect to the second accommodating portion 56, and the so-called first engaging means 15 is not locked, in other words, it is in the unlocked state.
12A shows the first engagement means 15 when the mobile terminal 10 is in the closed state, and FIG. 12B shows the first engagement means 15 when the mobile terminal 10 is in the laterally open state.

As shown in FIG. 9, the upper housing magnet 63 is disposed by insert molding in the very vicinity of the side of the protruding axis 65 of the engaging pin 45 in the first accommodating portion 55, so that the minimum necessary magnetic force is generated. The engaging pin 45 can be reliably protruded from the lower housing 11 without using a strong magnet that may affect the electronic components in the upper housing 12.
Further, since the upper casing magnet 63 is insert-molded in the first housing portion 55, it is not necessary to separately arrange (assemble) the upper casing magnet 63 separately.

Next, when the portable terminal 10 shifts from the closed state to the vertically opened state, that is, the upper housing 12 starts to rotate around the first rotation shaft 31 with respect to the lower housing 11, and the lower housing 11 In the transition state between the open state and the closed state in which the surface 11A of the upper housing 12 and the surface 12A of the upper housing 12 are separated from each other, the top of the first protrusion 51 from the first storage 55 and the second storage 56 And the 2nd protrusion part 52 begins to come out.
At this time, since the opening 58A of the first housing portion 55 and the opening of the second housing portion 56 are continuous along the surface 12A of the upper housing 12 by the return spring 47, the first housing portion 55 and the second housing portion are accommodated. The tops of the first protrusions 51 and the second protrusions 52 smoothly come out of the part 56 and begin to be detached from the second storage part 56.

  Then, as the surface 11A of the lower housing 11 and the surface 12A of the upper housing 12 are separated from each other, the influence of the magnetic force of the upper housing magnet 63 on the engaging pin 45 decreases, and the lower surface relative to the engaging pin 45 is relatively lowered. When the influence of the magnetic force of the housing magnet 48 exceeds the influence of the magnetic force of the upper housing magnet 63, the engagement pin 45 is applied by the magnetic force of the lower housing magnet 48 until the second protrusion 52 comes into contact with the upper surface 49 </ b> A of the holding portion 49. Is pulled into the lower housing 11, whereby the engaging pin 45 is accommodated in the lower housing 11 so that the top of the first protrusion 51 and the second protrusion 52 do not protrude from the surface 11 A of the lower housing 11. Is done.

Thus, since the engagement pin 45 is housed in the lower housing 11 from the start of the transition from the closed state to the vertical open state until the complete vertical open state, the user's voice call The engagement pin 45 interferes with the face, or the finger of the user who operates the operation unit 23 at the time of reading / writing / transmission / transmission of mail, Web browsing, various settings, etc. interferes with the engagement pin 45 and the operability of the operation unit 23 is reduced. There is no risk of damage or damage to the engagement pin 45.
Since the engagement pin 45 is housed in the lower housing 11 so that the lower housing magnet 48 and the stopper 50 do not contact with each other, for example, the lower housing magnet 48 and the stopper 50 are in contact with each other. In comparison, the portable terminal 10 can quickly protrude from the surface of the lower housing 11 when it is closed again.

Subsequently, when the mobile terminal 10 shifts from the closed state to the laterally open state, that is, the upper housing 12 starts rotating around the second rotation shaft 32 with respect to the lower housing 11, and the lower housing 11 When the surface 11A of the upper housing 12 and the surface 12A of the upper housing 12 are separated from each other, the second housing portion 56 follows the upper housing 12 and rotates so as to wind up the second protrusion 52, but the edge of the opening 58A The rotation of the first accommodating portion 55 is restricted by contacting the side surface of the first projecting portion 51, and the return spring 47 is rotated relative to the upper housing 12 while being compressed in the winding direction. The state where the opening 58A faces the surface 11A of the body 11 is maintained.
FIG. 11 is a perspective view showing a state when the upper housing 12 is rotated by a predetermined angle about the second rotation shaft 32 with respect to the lower housing 11 from the closed state of the mobile terminal 10.

As shown in FIG. 10A, in the second housing portion 56, the inner surface 61 orthogonal to the openings 56C and 56D is a smooth curved surface. The inner surface 61 is formed by a plurality of curved surfaces whose curvature radii R1 to R5 continuously increase from the innermost part 61A farthest from the opening 56C toward the front part 61B closest to the opening 56C.
That is, since the curvature radius of the inner surface 61 orthogonal to the openings 56C and 56D is continuously reduced from the entrance side to the back side, the second housing portion 56 rotates following the upper housing 12. In this case, the peripheral surface of the second projecting portion 52 of the engagement pin 45 can be captured and securely held in the lightening portion 56B.

Specifically, the second protrusion 52 of the engagement pin 45 can be smoothly guided from the opening 61B into the opening 61 of the second storage part 56, so that the so-called second protrusion 52 can be easily picked up.
At this stage, since the peripheral surface of the second protrusion 52 is covered with the second accommodating portion 56, the engagement pin 45, which is the first engagement portion, cannot be removed from the second engagement portion 46, and the first engagement The joining means 15 engages the longitudinal ends of the lower housing 11 and the longitudinal ends of the upper housing 12 so as to be in a so-called locked state.

  In the present embodiment, the upper casing 12 is rotated around the second rotation axis 32 with respect to the lower casing 11 from the closed state of the mobile terminal 10, and the surface 11 </ b> A of the lower casing 11 and the upper casing 11 are rotated. When the sandwiching angle with the surface 12A of the body 12 is about 30 degrees or more, the second projecting portion 52 cannot be extracted from the second accommodating portion 56 and is locked by the first engaging means 15.

  And since the curvature radius of the inner surface 61 of the 2nd accommodating part 56 is continuously small toward the back | inner side from the entrance side, it is the engagement pin 45 from the lower housing | casing 11 until the stopper 50 contacts the holding | maintenance part 49. Is pulled out and the mobile terminal 10 is in a completely laterally open state, the axis of the second protrusion 52 of the engagement pin 45 is arranged along the second rotation shaft 32.

According to the mobile terminal 10 of the embodiment as described above, the engaging pin 45 as the first engaging portion protrudes from the lower housing 11 by the magnetic force of the upper housing magnet 63 in the closed state, and the second engaging portion 46. Are inserted into the first housing portion 55 and the second housing portion 56 but are not locked, and the engaging pin 45 is housed in the lower housing 11 by the magnetic force of the lower housing magnet 64 in the vertically opened state, and in the horizontally opened state. Since the second housing portion 56 that follows the upper housing 12 is locked, the first engaging means 15 assists the second rotating member 34 that cantilever-supports the upper housing 12.
Therefore, according to the mobile terminal 10, even when an external force is applied due to a drop or an impact in a state between the closed state and the laterally opened state or in a completely laterally opened state, the upper housing 12, the connecting portion 13, The load is not concentrated on a specific part of the two-rotating member 34 or the like, and there is little possibility of breakage.

In the above-described embodiment, the first engagement means 15 in which the inner surface 58 of the first accommodating portion 55 is a smooth surface is exemplified, but the first engagement means 15A shown in FIG. 16 is also included in the present invention.
In the first engagement means 15A shown in FIG. 16, a protrusion 58D is provided on the inner surface 58C of the first accommodating portion 55A. On the other hand, a recess 51B is provided on the side surface of the first protrusion 51A of the engagement pin 45A inserted into the first housing 55A.

  Such first engaging means 15A is configured such that when the portable terminal 10 is changed from the closed state to the laterally opened state, that is, the upper housing 12 rotates about the second rotation shaft 32 with respect to the lower housing 11. The first housing portion is started even when the angle between the surface 11A of the lower housing 11 and the surface 12A of the upper housing 12 is less than about 30 degrees (low angle (obtuse angle)) and the locked state is not reached. Since the protrusion 58D of 55A and the recess 51B of the engagement pin 45A are engaged, it is possible to prevent the engagement pin 45A from falling out of the second accommodating portion 55A even when an external force due to impact or the like is applied to the mobile terminal. it can.

In the above-described embodiment, the first housing portion 55 is rotated with respect to the upper housing 12 and the second housing portion 56 is fixed to the upper housing 12. However, the present invention is limited to this. Instead, depending on the shape of the engagement pin 45, the surface 12A of the upper housing 12 may have an opening.
For example, a configuration in which a part of the opening is connected to the side surface of the upper housing 12 may be configured such that a part of the engagement pin 45 is caught in the opening in the laterally open state.

  In the above-described embodiment, the example in which the engagement pin 45 is formed in the substantially L shape by the first protrusion 51 and the second protrusion 52 has been described. It is also possible to form an L shape opposite to the T shape, the ball shape, or the engagement pin 45.

Next, a second embodiment of the present invention will be described.
In the first embodiment described above, the first projecting portion 51 and the second projecting portion 52 constituting the engaging pin 45 are integrally formed. However, as shown in FIG. The two protrusions 52 can also be configured separately. For example, the rotation shaft 51C is provided upward from the upper end surface of the first protrusion 51. On the other hand, the rotation shaft 51C is inserted into the separate second protrusion 52 and the second protrusion 52 is rotated. A shaft hole 52C that is movably supported is provided.

  Thereby, since the 2nd protrusion part 52 becomes rotatable, the effect | action and effect similar to 1st Embodiment mentioned above can be acquired. When the rotation angle of the second protrusion 52 is restricted, the rotation shaft 51C has, for example, a rectangular cross section, and the rotation shaft 51C has a shape capable of rotating by a predetermined angle as a cross section of the shaft hole 52C. Can do. Alternatively, both the rotation shaft 51C and the shaft hole 52C may have a circular cross section, and a stopper that defines the rotation range of the second protrusion 52 may be provided separately.

  According to the present invention, the second accommodating portion provided with the magnet of the second engaging portion attracts the engaging pin formed of a magnetic body by a magnetic force to cause the engaging pin to protrude from the surface of the first housing. By rotating the two housings around the second rotation axis, the second protrusion is accommodated in the second accommodating portion and the engaging pin is locked. In addition, since the second projecting portion can be rotated about the axis of the first projecting portion, the engagement is insufficient when the engagement pin does not project sufficiently or the second projecting portion is not in a predetermined position. In the combined state, when an external force that moves the second housing relative to the first housing is applied, the engagement pin comes out of the second engagement portion. It has the effect that the surroundings of the second engaging portion in the housing can be prevented from being damaged, and the first housing and the second housing are connected via the connecting portion, and from the closed state to the vertically opened state, It is suitable for application to a portable terminal that can be opened and closed in a horizontally open state.
