Description

  The present invention relates to a portable terminal in which a rotation-side casing is rotatably supported from a vertically long state to a horizontally long state or from a horizontally long state to a vertically long state.

  In recent years, with the start of digital terrestrial television broadcasting, mobile terminals represented by mobile phones have come to have a TV reception function and an Internet connection function. For this reason, it is necessary for the portable terminal to improve both portability and to make the image easier to see by enlarging the display screen. Furthermore, due to the nature of TV images and Internet screens, there is a need to view TVs and connect to the Internet with the display screen in a horizontally long state.

  Therefore, for example, as in Patent Document 1, the first casing and the second casing are connected to each other so that the first casing and the second casing can be folded and opened freely, and the liquid crystal display unit is connected to the first casing in a vertically long state and a horizontally long state. There is known a foldable mobile phone which is supported so as to be switchable.

By the way, there are cases where an opening is provided in a housing in an electronic device such as a portable terminal. As a technique for closing such an opening, for example, as shown in Patent Document 2, a cartridge insertion port is closed when a cartridge is not inserted. It is known to provide one shutter and a second shutter that slides along the main body and closes the cartridge insertion slot when the cartridge is loaded.
Japanese Patent Laid-Open No. 2006-21576 JP-A-63-146267

  In the portable terminal such as Patent Document 1, when the first casing and the second casing are folded, the first casing, the liquid crystal display unit (rotary side casing), and the second casing Therefore, there is a problem that the first casing portion protrudes and does not always look good. In particular, when the rotation-side casing is in a horizontally long state, the rotation-side casing is supported only by the first guide pins and the second guide pins, and there is a problem that wobbling easily occurs.

  Therefore, in order to improve the appearance and stably support the rotation side casing, a rotation support mechanism that rotatably supports the rotation side casing from the vertically long state to the horizontally long state or from the horizontally long state to the vertically long state, It is conceivable to sandwich the moving opening formed in the middle in the thickness direction on the side surface of the rotating housing in a sandwich shape.

  However, when such a moving opening is provided, there is a problem that the opening is conspicuous and the appearance is deteriorated, or dust and fingers are mistakenly entered.

  Therefore, application of the shutter structure as described in Patent Document 2 is conceivable, but this shutter structure is a complicated structure in which two shutters are provided, and also requires a large space, so that it is as narrow as a portable terminal. There is a problem that it cannot be applied when a shutter is provided in the space.

  Also, in the conventional shutter structure, it is normal for an object moving in the opening to enter and exit the opening while moving linearly. Therefore, the conventional shutter structure is used to open and close the opening through which the rotating object enters and exits. There was a problem that it was not applicable.

  The present invention has been made in view of such a point, and an object of the present invention is to make a rotation support mechanism that supports a rotating rotation-side casing appear without hindering the rotation operation of the rotation-side casing. It is to be able to be stored in the rotation side casing well.

  In order to achieve the above object, according to the present invention, the opening for moving the corner portion of the rotation-side casing is closed in the horizontally long state, and a shielding member is provided that is accommodated in the rotation-side casing in the vertically long state.

Specifically, in the first invention,
A rotation side housing;
A rotation support mechanism for rotatably supporting the rotation-side housing from a vertically long state to a horizontally long state or from a horizontally long state to a vertically long state;
An opening for movement that is formed in the middle in the thickness direction on the side surface of the rotation-side casing, and that allows the rotation support mechanism to move as the rotation-side casing rotates;
The rotary support mechanism that moves in the moving opening is slid in the thickness direction of the rotating casing, and the moving opening at the corner of the rotating casing is closed in the horizontally long state. And a shielding member that is completely accommodated in the rotation-side casing.

  According to the above configuration, when the shielding member that has closed the moving opening located in the corner portion of the rotating housing in the horizontally long state is switched to the vertically long rotating housing, the rotation support mechanism moves the moving opening. Since it slides in the thickness direction and is accommodated in the rotation-side casing so as to be pushed away as it moves in, the rotation operation of the rotation-side casing is not hindered. On the other hand, the moving opening from which the rotation support mechanism comes out as it rotates from the vertically long state to the horizontally long state is gradually closed by the shielding member that slides out from the rotation side housing, so that the vertically long state and the horizontally long state In any state, the moving opening is blocked and looks good, and dust does not enter from the moving opening.

In the second invention, in the first invention,
The shielding member is
An L-shaped shielding member main body in plan view that can be accommodated in a shielding member accommodating portion provided at the periphery of the opening for movement in the corner portion of the rotation-side housing;
And an urging member that is accommodated in the shielding member accommodating portion and urges the shielding member main body in a direction to close the opening for movement.

  According to the above configuration, since the shielding member is urged in the direction to close the moving opening by the urging member, when the rotation support mechanism rotates from the state accommodated in the moving opening to the horizontally long state in the vertically long state Further, the shielding member main body is urged by the urging member and automatically closes the moving opening. For this reason, the opening / closing operation of a shielding member becomes unnecessary.

In the third invention, in the second invention,
In the shielding member main body, in the direction in which the shielding member main body is accommodated in the shielding member accommodating portion at a portion where the rotation support mechanism first contacts when the rotation-side casing rotates from the horizontally long state to the vertically long state. A tapered portion for guiding is formed.

  According to the above configuration, when the rotation-side casing rotates from the horizontally long state to the vertically long state, the rotation support mechanism first comes into contact with the tapered portion of the shielding member body, so that the shielding member body is shielded by being guided by the tapered portion. It is smoothly accommodated in the member accommodating portion.

In the fourth invention, in the second or third invention,
The urging member is in-molded on one side of the shielding member body.

  According to the above configuration, even if the urging member that requires elasticity and the shielding member main body, whose appearance is important, are made of different materials, the urging member and the shielding member main body are integrally molded. As the number of parts is reduced, a complicated shape can be formed because it is a molded product.

In the fifth invention, in the fourth invention,
The biasing member is made of a leaf spring, and the embedded portion of the leaf spring embedded in the shielding member body and the exposed portion exposed to the outside from the shielding member body are connected at the center in the longitudinal direction of the exposed portion. The leg portions formed only at both ends in the longitudinal direction of the exposed portion are in contact with the bottom surface of the shielding member housing portion, and the shielding member body is inclined so as to twist the coupling portion, and the exposed portion is The connecting portion is configured to be deformed and slide in the thickness direction of the rotation side casing.

  According to said structure, since the embedding part which has elasticity is embedded in the shielding member main body, and the embedding part and the exposed part are connected only by the connection part, a shielding member main body inclines, twisting a connection part. Moreover, when the whole shielding member main body is pushed to the bottom surface side of the shielding member housing portion, the exposed portion that contacts the shielding member housing portion is deformed by the pair of legs so that the connecting portion is slid to the bottom surface side. Thus, the shielding member main body slides smoothly and is accommodated in the shielding member accommodating portion, so that the shielding member does not hinder the rotation of the rotation side casing. Further, when the rotation support mechanism comes into contact with the other side of the shielding member main body not provided with the urging member, the other side is inclined, and the side where the other urging member is provided is centered in the longitudinal direction. However, the shielding member does not hinder the rotation of the rotation-side casing because the leaf spring is inclined or deformed in the shielding member housing portion.

In a sixth invention, in any one of the first to fifth inventions,
In the horizontally long state, when the moving opening is completely closed by the shielding member, the surface of the shielding member and the surface of the rotating housing are continuous.

  According to said structure, when a rotation side housing | casing is in a horizontally long state, since a shielding member and a rotation side housing | casing form the continuous surface, it is good in touch and is also hard to enter dust.

In a seventh invention, in any one of the first to sixth inventions,
The rotation support mechanism is
A first slide member and a second slide member that slide during the rotation;
A first slide guide and a second slide guide that allow the first slide member and the second slide member to slide in different directions are provided.

  That is, the first slide guide and the second slide guide can be guide holes, guide grooves, guide rails, or the like that guide linear movement or curved movement, and may be linear or curved. The first slide member and the second slide member have an axial shape, a U-shaped projection, or the like according to the shape of the first slide guide and the second slide guide. As described above, by optimizing the shapes of the first slide guide and the second slide guide, an optimal rotation locus of the rotation side housing can be obtained. In addition, for example, the rotation-side casing can be rotated clockwise and returned to the original position, the rotation-side casing can be rotated counterclockwise and returned to the original position, or the clockwise direction and the counterclockwise direction. It is possible to rotate in any direction around and rotate back. In addition, since the rotation-side casing can be rotated so as not to contact other members, it is not necessary to round the corners of the rotation-side casing, and the display display can be enlarged.

In an eighth invention, in any one of the first to seventh inventions,
The rotation support mechanism is connected to a stationary housing,
A display is built in at least one of the rotating side casing and the fixed side casing.

  That is, the display display may be provided only in one of the rotation side case or the fixed side case in both the rotation side case and the fixed side case, and in particular, the display display is provided on the rotation side case side. Since the display screen is switched to the vertically long state or the horizontally long state when the user is in a comfortable state, it is possible to comfortably view the TV and read / write horizontally written text in an appropriate screen state.

In the ninth invention, in the eighth invention,
The display is built in the rotating housing,
An operation unit is built in the fixed housing.

  According to the above configuration, if the rotation-side casing is set to the horizontally long state when receiving TV or the like, the image in the horizontally long state can be viewed without rotating the fixed-side casing. Can be used with the same normal key arrangement as when the rotary casing is in the vertically long state. For this reason, it is possible to comfortably perform an input operation in an interactive service such as teleshopping while viewing a horizontally long image.

In a tenth aspect, in the ninth aspect,

The rotation support mechanism is coupled to the fixed housing via the hinge portion.

  According to the above configuration, when the rotation-side casing and the stationary-side casing are folded around the hinge portion, the rotation support mechanism is accommodated in the movement opening of the rotation-side casing. Looks like a normal foldable mobile terminal and looks good. In addition, it is possible to see the rotation-side casing in the horizontally long state with the fixed-side casing in hand.

In an eleventh aspect, in the tenth aspect,
The rotation-side casing is configured to rotate while leaving a predetermined distance from the hinge portion.

  According to the above configuration, since it is not necessary to round the corners of the rotating side housing to avoid contact with the hinge portion, the rotating side housing can be enlarged and a display display is provided on the rotating side housing. The display becomes larger and the image becomes easier to see.

  As described above, according to the present invention, for the movement that allows the movement of the rotation support mechanism that rotatably supports the rotation-side casing in the vertically long state or the horizontally long state in the middle in the thickness direction on the side surface of the rotation-side casing. The rotation support mechanism is formed by forming an opening, and closing the opening for moving the corner portion of the rotation side casing in the horizontally long state and completely accommodating the shielding member in the rotation side casing in the vertically long state.

The lower shielding member 41 includes an L-shaped lower shielding member main body 41e in a plan view accommodated in the shielding member accommodating portion 42. The lower shielding member main body 41e is made of, for example, a resin molded product, and a lower appearance portion 41a that shields the lower opening 25a, and a side appearance portion that is shorter than the lower appearance portion 41a and shields a part of the side opening 25b. 41b. In the lower shielding member main body 41e, a taper portion 41c is formed at a portion where the rotation support mechanism 10 first contacts when the rotation-side housing 3 rotates from the horizontally long state to the vertically long state, that is, at the tip of the side appearance portion 41b. Is formed. As shown in FIG. 38, the taper portion 41c is in a direction in which the lower shielding member main body 41e is accommodated in the shielding member accommodating portion 42 (upward to the left when viewed from the inside of the rotation side housing 3 in FIG. 38). It has an inclined flat surface.

  A leaf spring 43 made of a stainless steel plate or the like is connected to the lower appearance portion 41a. The leaf spring 43 is accommodated in the shielding member accommodating portion 42 together with the lower shielding member main body 41e, and plays a role of urging the lower shielding member main body 41e in the direction of closing the movement opening 25. The leaf spring 43 includes an embedded portion 43a that is integrally molded with the lower external appearance portion 41a, and an exposed portion 43b that is accommodated in the shielding member accommodating portion 42, and the embedded portion 43a and the exposed portion 43b are provided. It is connected only at the connecting portion 43c at the longitudinal center of the exposed portion 43b. Thus, if it is an in-mold molded product, even if it comprises the leaf | plate spring 43 which needs elasticity, and the lower shielding member main body 41e which attaches importance to an external appearance with a separate material, these leaf | plate spring 43 and a lower shielding member main body Since 41e is integrally formed, the number of parts is reduced and a complicated shape can be formed because it is a molded product.

  Further, leg portions 43d extending toward the bottom surface 42a are formed at both ends in the longitudinal direction of the exposed portion 43b. The pair of leg portions 43d are in contact with the bottom surface 42a of the shielding member accommodating portion 42 and are not coupled to the shielding member accommodating portion 42, and the exposed portion 43b is inclined or deformed in the shielding member accommodating portion 42. It is housed so that you can. With such a configuration, as the rotation support mechanism 10 rotates, the side external appearance part 41b abutted from the taper part 41c gradually moves in the thickness direction of the rotation side housing 3 as shown in FIG. Is rotated about the axis extending in the longitudinal direction of the lower appearance portion 41a, the leg portion 43d is inclined in the shielding member accommodating portion 42, and the lower appearance portion 41a side is pressed as shown in FIG. Then, the connecting portion 43c is swung while being twisted. When the entire lower appearance portion 41a is pushed down, the rotation support mechanism 10 passes smoothly because the exposed portion 43b is largely bent in a substantially M shape as the connecting portion 43c moves toward the bottom surface 42a. It is configured. After passing through the rotation support mechanism 10, it is pushed back by the leaf spring 43 and slidably moves within the shielding member accommodating portion 42 so as to close part of the lower opening 25a and the side opening 25b again. The lower shielding member 41 also looks good if it is the same material and the same color as the back side cabinet 3b.

  With this configuration, in the vertically long state shown in FIGS. 2 and 3, the side opening 25b is closed by the decorative side surface portion 17b and the side shielding member 40, and as shown in FIG. 42, the lower opening 25a is closed. Accommodates the lower side of the guide plate 16, the front-side hinge housing 17 and the back-side hinge housing 18 of the rotation support mechanism 10. 10, the guide plate 16, the front hinge housing 17 and the rear hinge housing 18 are accommodated in a part of the side opening 25b, and the remaining portion of the side opening 25b and the lower opening are opened. 25a is closed by a lower shielding member 41. When these shielding members 40 and 41 are closed, the surface of the shielding members 40 and 41 and the surface of the rotation side housing | casing 3 are substantially continuous.

-Action-
Next, the operation of the mobile phone 1 according to the present embodiment will be described.

  First, as shown in FIG. 2, when the mobile phone 1 is not used or in a standby state, the rotation-side housing 3 and the fixed-side housing 5 are in a folded state. At this time, the rotation support mechanism 10 is accommodated in the movement opening 25 of the rotation side housing 3. That is, the side opening 25b is covered with the side shielding member 40 and the decorative side surface portion 17b, and the surface of the rotation side housing 3 looks almost continuous. Therefore, the rotation support mechanism 10 does not protrude, and at first glance, the rotation support mechanism 10 looks like a normal foldable mobile phone 1 without the rotation support mechanism 10, and the movement opening 25 is rotationally supported with the side shielding member main body 40 a. Since it is completely blocked by the decorative side surface portion 17 b of the mechanism 10, dust does not enter from the movement opening 25. Further, as shown in FIG. 20, since the rotation end 40e is completely fitted in the recess 17e, even if the side shielding member main body 40a is pushed in with a finger, the recess 17e does not rotate inward. For this reason, a finger is not accidentally pinched. On the other hand, paying attention to the lower shielding member 41, as shown in FIGS. 36, 39 and 42, the entire lower shielding member main body 41e with the pair of leg portions 43d in contact with the bottom surface 42a of the shielding member accommodating portion 42. Is pushed to the bottom surface 42a side, the embedded portion 43a of the leaf spring 43 and the exposed portion 43b are connected only by the connecting portion 43c and are easily deformed, so that they are at the center of the pair of leg portions 43d. The exposed portion 43b is greatly bent so that the connecting portion 43c moves toward the bottom surface 42a, and the lower shielding member main body 41e slides and is completely accommodated in the shielding member accommodating portion 42.

  And as shown in FIG. 3, when the rotation side housing | casing 3 and the stationary side housing | casing 5 are opened, the display 2 and the operation part 7 will appear. When a normal call or mail transmission / reception is performed, the display 2 is set in a vertically long state and used while inputting keys on the operation unit 7.

  On the other hand, when viewing a horizontally long image such as when viewing digital terrestrial television broadcasting or connecting to the Internet, the user rotates the display 2 to switch from the vertically long state to the horizontally long state.

  First, as shown in FIG. 4, the user rotates the lower end side corner portion 2 b of the display 2 in a clockwise direction when viewed from the surface. At this time, as shown in FIGS. 20 and 21, the second slide pin 12 at the lower end of the second guide groove 14 as viewed from the back of the mobile phone 1 moves to the upper end side, and the left end of the first guide groove 13. The first slide pin 11 is moved to the vicinity of the center. At this time, since the upper end portion 17d of the front side hinge housing 17 presses the rotation end 40e, the side shielding member 40 rotates. Further, when the side shielding member main body 40a is pushed by the upper end portion 17d with the rotation, as shown in FIG. 21, the rotating end 40e comes out of the recess portion 17e and the lock is released. That is, when the rotation is started, the inclination of the first guide groove 13 on the left side when viewed from the side where the first slide pin 11 is located, that is, from the back side is increased, so that the second slide pin 12 is largely moved upward. In addition, since the lower end side of the second guide groove 14 is inclined upward to the left when viewed from the rear side, even when the side shielding member 40 is locked, the unlocking direction, that is, the rear side is viewed from the rear side. Thus, the rotation side housing 3 is guided in the upper left direction. For this reason, the rotation end 40e locked in the vertically long state of the rotation side housing 3 is easily pulled out of the recess 17e at the start of rotation and unlocked. Thus, the side shielding member 40 is prevented from obstructing the rotation of the rotation support mechanism 10 with a simple configuration. As shown in FIGS. 4 and 7, the rotation support mechanism 10 coming out from the movement opening 25 is covered with the decorative thin plate 19 at the front and back, so that it looks good.

  Next, the display 2 is switched to the landscape state shown in FIG. At this time, as shown in FIGS. 21 to 23, the second slide pin 12 located on the upper end side of the second guide groove 14 as viewed from the back of the mobile phone 1 moves to the lower end, and the center of the first guide groove 13 is reached. The first slide pin 11 located in the vicinity moves to the right end. As described above, the first slide pin 11 of the display display 2 slides in the first guide groove 13 by the rotation support mechanism 10, and at the same time, the second slide pin 12 of the display display 2 moves in the second guide groove 14. Move the slide.

  Further, as shown in FIGS. 7 to 10 and FIGS. 21 to 23, the rotation support mechanism 10 moves while gradually pushing the side shielding member 40, and after the movement, the side shielding member 40 gradually moves. Return to the original position. At the same time, as shown in FIGS. 35 and 41, when the rotation support mechanism 10 accommodated in the movement opening 25 comes out of the movement opening 25 when the rotation side housing 3 rotates, the lower shielding member Since the main body 41e is biased by the deformed leaf spring 43 in the direction of closing the moving opening 25, the main body 41e automatically slides out of the shielding member accommodating portion 42 and gradually closes the moving opening 25. For this reason, the opening / closing operation of the lower shielding member 41 is also unnecessary. As described above, due to the action of the coil spring 40 d and the leaf spring 43, the movement opening 25 is gradually opened even during the rotation, so that it is difficult for dust to enter the movement opening 25. Also, it is safe because fingers are not easily caught.

  Further, the lower end side corner portion 2b is guided and supported so as to move along a trajectory that maintains a certain gap with the hinge portion 4. For this reason, the display display 2 does not interfere with the hinge portion 4 even if the lower end of the display display 2 is not rounded along the radius centered on the support shaft as in the conventional case. For this reason, it is not necessary to round the corners of the rotation side housing 3, and the display 2 can be enlarged. For this reason, the image is easy to see.

  Further, since the rotation support mechanism 10 always moves in the movement opening 25 while the rotation-side housing 3 is rotating, the rotation support mechanism 10 is only wobbled within the clearance with the movement opening 25 and the rotation operation is stabilized. Further, if the protrusion 27 is always in contact with the slide recess 28 of the rotation side housing 3, it is possible to prevent further rotation of the rotation side housing 3 with a simple configuration. In addition, the protrusion 19a of the decorative thin plate 19 minimizes the gap between the decorative thin plate 19 and the inside of the rotation side housing 3, thereby preventing wobbling during rotation.

  In this way, since the display screen is switched to the vertically long state or the horizontally long state, comfortable TV viewing and Internet connection are possible in an appropriate screen state. If the rotation-side casing 3 is set to be in the horizontally long state, the image in the horizontally long state can be viewed without rotating the fixed-side casing 5, so that the operation unit 7 of the fixed-side casing 5 can be It can be used with the same normal key arrangement as when in the state. For this reason, it is possible to comfortably perform an input operation in an interactive service such as teleshopping while viewing a horizontally long image.

  Even in the horizontally long state shown in FIG. 5, the central portion in the left-right direction of the display display 2 is positioned substantially at the center in the left-right direction of the rotation-side housing 3. In this state, the rotation-side casing 3 in the horizontally long state can be viewed by holding the fixed-side casing 5 in the hand. Then, a setting is made so that a horizontally long image is displayed on the display 2 in a large size, and a user enters a quiz program from the TV while inputting keys on the operation unit 7 or uses TV shopping or bank transfer through the TV. . Further, by placing the back side of the fixed-side housing 5 on a desk in a state where the rotation-side housing 3 is in a horizontally long state and opened, a TV image is displayed on the display device 2 in the horizontally long state for a long time. Can be viewed. As shown in FIG. 23, the side shielding member 40 is accommodated substantially perpendicularly to the hinge portion 4 between the lower end portion 30 a of the electronic component and the decorative side surface portion 17 b of the front side hinge portion housing 17. Thus, the side shielding member 40 is similarly rotated 90 ° while the rotation-side casing 3 is rotated 90 ° from the vertically long state to the horizontally long state. Even when the rotation-side housing 3 is in the horizontally long state, the portion where the rotation support mechanism 10 is housed in the movement opening 25 of the rotation-side housing 3 and the side shielding member 40 is closed is the rotation support mechanism. 10 enters. At this time, the surfaces of the lower shielding member 41, the rotation support mechanism 10, and the rotation side housing 3 are continuous. For this reason, since a continuous surface is formed around the movement opening 25 and its periphery, the appearance is good and the touch is good, and dust does not enter from the movement opening 25. Furthermore, the rotation support mechanism 10 does not protrude and looks good.

  Further, after use, contrary to the above, the lower right corner portion 2b on the right side of the display 2 is rotated counterclockwise when viewed from the surface, and the display 2 is returned to the vertically long state. Also at this time, the rotation support mechanism 10 moves while gradually pushing away the side shielding member 40 and the lower shielding member 41. As shown in FIG. 38, when the rotation-side casing 3 rotates from the horizontally long state to the vertically long state, the rotation support mechanism 10 first comes into contact with the tapered portion 41c of the side appearance portion 41b in the side opening 25b. When the rotation support mechanism 10 further moves, the lateral appearance portion 41b is inclined by the action of the taper portion 41c, and the lower appearance portion 41a rotates around its longitudinal direction. Also at this time, since the leg portion 43d is inclined in the shielding member accommodating portion 42, the rotation is not hindered.

  As shown in FIG. 41, when the rotation support mechanism 10 moves to the lower opening 25a, the lower appearance portion 41a is pushed down and tilted around the connecting portion 43c while twisting the connecting portion 43c. Further, as the rotation support mechanism 10 moves, the lower appearance portion 41a is pushed down while deforming the exposed portion 43b. For this reason, the lower shielding member main body 41e is smoothly accommodated in the shielding member accommodating portion. Thus, even in the counterclockwise direction, the side shielding member 40 and the lower shielding member 41 do not hinder the rotation operation of the rotation side housing 3. Further, the side shielding member 40 and the lower shielding member 41 gradually return to their original positions by the action of the coil spring 40d and the leaf spring 43 after the movement.

  And the rotation side housing | casing 3 and the stationary side housing | casing 5 are folded and it is set as a standby state.

-Effect of the embodiment-
With the configuration described above, the movement opening 25 that allows movement of the rotation support mechanism 10 that rotatably supports the rotation-side housing 3 in the vertically long state or the horizontally long state is provided in the middle in the thickness direction on the side surface of the rotation-side housing 3. The lower shielding member 41 is formed so that the movement opening 25 of the lower end side corner portion 2b of the rotation side housing 3 is closed in the horizontally long state and is completely accommodated in the shielding member accommodating portion 42 in the vertically long state. Thus, the rotation support mechanism 10 can be housed in the rotation-side casing 3 with good appearance without hindering the rotation operation.

  Further, even if an unexpected impact is applied to the rotation-side housing 3, the load is transmitted to the periphery of the movement opening 25, so that the load is prevented from being concentrated only on the rotation support mechanism 10, and the rotation support mechanism 10. Can be effectively prevented.

  Moreover, since the contact with the hinge part 4 can be avoided by setting the shapes of the first guide groove 13 and the second guide groove 14 as in the above embodiment, it is not necessary to round the corners of the rotation-side housing 3. The rotation side housing 3 can be enlarged. For this reason, it is possible to comfortably view TV images and Internet images by enlarging the display 2.

(Other embodiments)
The present invention may be configured as follows with respect to the above embodiment.

  That is, in the above embodiment, the display display 2 is built in the rotation-side casing 3, but the display display 2 can be the rotation-side casing 3 or the fixed-side casing in both the rotation-side casing 3 and the fixed-side casing 5. It may be provided only on one side of the body 5. Further, in the above embodiment, the operation unit 7 is provided only in the fixed housing 5, but the display unit 2 may be provided in the fixed housing 5 only in the rotation housing 3. Further, the display 2 may be provided on the rotation-side casing 3, and a simple operation unit 7 including function keys or the like may be provided in part.

  The shapes of the first guide groove 13, the second guide groove 14, the first slide pin 11, and the second slide pin 12 in the above embodiment are merely examples. That is, the first guide groove 13 and the second guide groove 14 can be guide holes, guide grooves, guide rails, or the like that guide linear movement or curved movement, and can be linear or curved. Good. The first slide pin 11 and the second slide pin 12 have an axial shape, a U-shaped projection, or the like according to the shape of the first guide groove 13 and the second guide groove 14.

Biasing mechanism for assisting the rotation urges the at least one rotational supporting mechanism 10 in the first slide pin 11 and second slide pin 1 2 may be provided. By the urging mechanism, the rotation-side casing 3 can be easily rotated and operated with one hand, and the rotation-side casing 3 is stabilized in a horizontally long state or a vertically long state.

  The urging mechanism may be a torsion coil spring having one end rotatably connected to the first slide pin 11 or the second slide pin 12 and the other end rotatably connected to the guide plate 16. If it does in this way, rotation assistance of a rotation side case can be performed with simple composition.

  Further, the rotation support mechanism 10 may be provided with a biasing mechanism that biases the first slide pin 11 to assist the rotation. As this urging mechanism, one end is rotatably connected to the guide plate 16, and the other end is provided with a pressing member that presses the first slide pin 11, and the urging member is configured so that the urging member rotates and urges the pressing member. That's fine. With this urging mechanism, the rotation-side housing 3 can be easily rotated and operated with one hand, and the rotation-side housing 3 is stabilized in a horizontally long state or a vertically long state. And since the 1st slide pin 11 or the 2nd slide pin 12 is pressed via a press member, the urging | biasing direction of the urging | biasing member which generates urging | biasing force can be set freely. For this reason, since a compression coil spring or a tension coil spring can be used as the urging member, an increase in thickness can be suppressed even when the number of turns is increased, and the urging force can be increased while suppressing an increase in thickness.

  By optimizing the shapes of the first guide groove 13 and the second guide groove 14, an optimal rotation locus of the rotation side housing 3 can be obtained. In other words, in the above-described embodiment, the rotation-side housing 3 is rotated clockwise by the rotation support mechanism 10 from the vertically long state to the horizontally long state when viewed from the front, and is rotatable so as to return from the horizontally long state to the vertically long state. Although supported, it may be rotated counterclockwise. In that case, the rotation support mechanism 10 and the movement opening 25 may be disposed so as to be reversed left and right. In this case, the right side slope of the first slide guide is larger than the left side slope as viewed from the back side, and the second slide guide has a gently curved shape with the lower end side slightly inclined upward toward the right side. Therefore, even if the side shielding member 40 is locked in the vertically long state, the rotation-side housing 3 rotates so as to rise to the upper right when viewed from the back, so that the lock can be easily released.

  Further, for example, as shown in FIG. 43, the first guide groove 113 is formed in the guide plate 116 in the shape of a seagull such that the seagull is flying with its wings spread, and the second guide groove 114 is disposed above the first guide groove 113. It is possible to rotate both in the clockwise direction and in the counterclockwise direction, and to rotate back to the original direction. In this case, the movement openings 25 may be provided equally large on the left and right side surfaces of the rotation-side housing 3. Further, the side shielding member 40 and the lower shielding member 41 may be provided on the left and right sides, respectively, and the lower opening 25a may be shielded by being shared by the left and right lower shielding members 41. Further, if the inclination of the left and right outer end portions of the first guide groove 113 is further increased, the left and right side shielding members 40 are easily unlocked when the rotation is started from the vertically long state.

  In the above embodiment, the first slide pin 11 and the second slide pin 12 are each temporarily fixed by the plate-shaped temporary fixing plate 21, but the present invention is not limited to this, and the support mechanism fixing boss 3h itself is the first. The slide pin 11 and the second slide pin 12 may be used.

  In the above embodiment, the hinge boss portions 17 a and 18 a are provided on the left and right outer sides of the rotation side housing 3, and the bulging portion 5 a is provided on the upper side of the fixed side housing 5. The bulging portion extending from the lower end of the rotation side housing 3 may be sandwiched between the hinge boss portions. In this case, the extension portion 16d of the guide plate 16 may be extended to the bulging portion so that the signal line 20 is passed through the hinge shaft insertion hole 16e.

  In the above embodiment, the portable terminal is the foldable mobile phone 1, but the fixed-side casing 5 may be a so-called straight-type portable terminal that is connected to the rotating-side casing 3 so that it cannot be folded and opened. In that case, the rotation support mechanism 10 may be directly connected to the stationary housing 5. Even in this straight type portable terminal, the rotation support mechanism 10 can be accommodated in the movement opening 25 of the rotation-side casing 3, so that the appearance is good.

  Furthermore, you may comprise so that the inside of the opening 25 for movement is movable at the time of rotation with the fixed side housing | casing 5. FIG. In this case, the fixed housing 5 can be made into a compact shape completely accommodated in the movement opening 25 of the rotation housing 3.

  In the above embodiment, the mobile terminal is a foldable mobile phone, but it may be a PHS, PDA, PC, mobile tool, electronic dictionary, calculator, game machine, or the like.

  In the above embodiment, the display 2 may be a liquid crystal display or an organic EL display. An organic EL display emits light by itself, consumes less power, has a wider viewing angle than a liquid crystal display, and does not require a backlight, and thus can be thinned. A liquid crystal display is cheaper and has a longer life than an organic EL display.
