Abstract

Disclosed are a rotation device and an opening/closing handheld terminal that are reduced in size. The disclosed rotation device is provided with: a rotational axle member; a holding member that rotatably holds the rotational axle member; and a movable member that is held by the holding member, can move between a first position and a second position, and is biased toward the first position. In the first position, the movable member abuts against the rotational axle member, thereby regulating the rotation of said rotating axle member. In the second position, the movable member does not abut against the rotational axle member and therefore does not regulate the rotation of said rotating axle member. The movable member is provided with a leg that receives a force, from outside the device, which moves the movable member in a direction counter to the aforementioned bias. When the rotational axle member is in a prescribed closed state, said rotational axle member allows the movable member to move to the first position, and becomes rotatable when the movable member is moved to the second position via the aforementioned leg. When the rotational axle member has rotated to an angle different from the rotation angle of the aforementioned prescribed closed state, part of the rotational axle member limits the range of motion of the movable member such that the movable member does not move to the first position as a result of the aforementioned bias.

Rotating device and openable portable terminal provided with the same

The present invention relates to an open / close portable terminal in which a first housing and a second housing are openably connected via a connecting portion, and a connecting portion thereof.

2. Description of the Related Art A foldable portable terminal is known in which a first case mainly having an operation unit and a second case mainly having a display unit such as a liquid crystal screen can be opened and closed via a hinge mechanism. The general hinge mechanism includes a first case, a second case, a connecting case that rotatably connects the first case and the second case, the connecting case, and the connecting case. A first hinge portion pivotally attaching a first housing around a first axis whose axis is a short axis direction of the first housing, the connection housing, and the second housing (2) A second hinge pivotally mounted about a second axis centering on the longitudinal direction of the housing, and the second hinge portion extends along the longitudinal direction of the connection housing. A plate-shaped first connection body fixed inside the body, a plate-shaped second connection body fixed inside the second case along the short direction of the second case, and the first connection A pivot attachment portion pivotally connecting the body and the second connection body about the second axis, the connection housing including the first hinge portion and the second hinge portion While connecting There is configured to cover the first connecting member (for example, see Patent Document 1).

In recent years, transmission and reception of mail, playing a game, and receiving a TV broadcast have been performed using the display unit and the operation unit of such a portable terminal. With the diversification of usage modes of such portable electronic devices, for example, when performing a call, transmission / reception of mail, or a game, the user can operate with one hand while viewing the rectangular display section in portrait orientation, A so-called vertically opened state in which the lower case (first case) and the upper case (second case) are opened in the longitudinal direction via the connection portion (hinge mechanism) to make the display portion and the operation portion vertically long. It is convenient to do. On the other hand, in the case of a game, a browser, or a TV reception, the first housing and the second housing are opened in the width direction (short direction) so as to use the display unit in landscape orientation. Is convenient.

For this reason, in the portable terminal described in Patent Document 1, the first housing and the second housing are vertically opened in the longitudinal direction and horizontally opened in the horizontal direction through the connecting portion (hinge mechanism). Is possible.

In addition, there are two housings, and a hinge for opening and closing and rotatably connecting the other housing with respect to any one of the housings is an opening and closing shaft rotatably supported by the opening and closing shaft supporting portion; A rotary shaft which is rotatably passed through the open / close shaft in an orthogonal state, an angle restricting piece provided so as to abut on the open / close shaft support portion and the open / close shaft, and a control flange projecting on the rotary shaft And a rotation restricting portion attached to the opening and closing shaft supporting portion and facing the restriction flange, and a mounting plate which is caulked and fixed to a tip end of the opening and closing shaft and prevents the opening and closing shaft from coming off. (For example, refer to patent document 2)

Further, it is known that the openable and closable first and second casings are electrically connected by an electric wire and the electric wire passes through a through hole provided in the hinge mechanism (see, for example, Patent Document 3) . The electric wire which has jumped out of the through hole may be bent and disposed.

Japanese Patent No. 4206118 Japanese Patent Application Laid-Open No. 2000-240636 Japanese Patent Application Publication No. 2007-122195

By the way, in recent years, along with the miniaturization of the open-close portable terminal, the miniaturization of the connecting part is also demanded. In response to such a demand, it is conceivable to reduce the diameter of the through hole, and further to miniaturize the pivoting portion and the connector.

However, in the connection portion of the conventional structure, when an external force that causes the connection body to tilt is applied and the supporting force of the other connection body is weakened with respect to one connection body, there is a problem that backlash easily occurs. Therefore, by increasing the distance between one coupling body and the other coupling body, it is possible to reduce the backlash as much as possible, but on the other hand, there is a problem that the coupling portion can not be miniaturized.

Moreover, in the hinge used for the connection part of conventional structure, the opening-closing axis | shaft and the rotating shaft are integrated. If the shaft diameter is set in order to ensure the strength of each shaft, there is no need to secure a space for disposing the rotation restricting portion along the open / close shaft. I had to secure it large enough. Then, if the rotation regulation method of a rotating shaft is disclosed without integrating, it can select suitably. Therefore, the proposal of the small rotation apparatus provided with rotation restrictions was desired.

In addition, when the electric wire is disposed in the through hole of the hinge mechanism, the electric wire protruding from the through hole is bent so as to form a large curvature as illustrated in FIG. 6 of Patent Document 2. Therefore, since the connecting portion for receiving the hinge mechanism must also accommodate the electric wire, it has to secure a space in which the electric wire is bent and disposed. At this time, if this space is large, the connecting portion becomes large.

The present invention has been made in view of the above circumstances, and was made to solve the above-mentioned problems, and it is an object of the present invention to provide a pivoting device which can be miniaturized and a closable portable terminal provided with the same. I assume.

The rotation device according to the present invention includes a rotation shaft member, a holding member for holding the rotation shaft member rotatably, and the rotation member held by the holding member and brought into contact with the rotation shaft member. Movable between a first position for restricting the rotation of the shaft member and a second position for releasing the rotation restriction of the rotation shaft member by releasing the contact with the rotation shaft member A movable member biased toward the first position, the movable member receiving a force for moving the movable member in a direction to resist the bias from the outside of the own device And the rotating shaft member permits movement of the moving member to the first position when in the predetermined closed state, and the moving member moves to the second position via the leg portion. When it is moved, it becomes rotatable, and at an angle different from the rotation angle in the predetermined closed state If you are moving, so that the moving member does not move to the first position by the urging limits the movable range of the movable member by a portion of the pivot shaft member.
Moreover, the opening-closing portable terminal of the present invention includes the above-described pivoting device.

According to the present invention, both the vertical opening and the horizontal opening can be made from the closed state, and when the state is shifted from the closed state to the vertical opening, the second housing is turned from the vertical opening to the horizontal opening direction. Can be regulated. Therefore, even if the user places a call while placing the second case on the head, it prevents the second case from rotating against the user's will, so it can be used freely with the conventional openable terminal. The present invention can provide a pivoting device which does not change and an open / close portable terminal provided with the same.

When the second housing is changed to the second direction and then rotated in the first direction to bring it into an abnormal state, the second housing is opposite to the first direction or opposite to the second direction. Since it can be pivoted, it can be easily restored to the normal state.

In addition, since the wiring space can be reduced, it is possible to avoid an increase in size of the terminal, etc., and to provide an open / close type terminal having a simple structure with a small number of parts and capable of vertical opening and horizontal opening while avoiding enlargement. Can.

The first Hall element 10 and the second Hall element 11 will be described. The first Hall element 10 detects the magnetic field of the first magnet 16 and outputs a detection signal to the control unit 26 because the first magnet 16 is in the close state when the main body unit 1 is in the closed state. In addition, since the first magnet 16 is separated when the main body 1 is in the first open state and the second open state, the first Hall element 10 can not detect the magnetic field of the first magnet 16. Does not generate a detection signal.

The second hall element 11 detects the magnetic field of the second magnet 34 and outputs a detection signal to the controller 26 because the second magnet 34 is in the close state when the main body 1 is in the closed state and in the first open state. . Moreover, since the 2nd magnet 34 will separate if the main-body part 1 is a 2nd open state, since the 2nd Hall element 11 can not detect the magnetic field of the 2nd magnet 34, the Hall element 11 does not generate a detection signal .

That is, when the first Hall element 10 detects the first magnet 16 and the second Hall element 11 detects the second magnet 34, the main body 1 is in the first closed state. When the first Hall element 10 does not detect the first magnet 16 and the second Hall element 11 detects the second magnet 34, the main body 1 is in the first open state. If the first Hall element 10 does not detect the first magnet 16 and the second Hall element 11 does not detect the second magnet 34, the main body 1 is in the second open state.

When the main body unit 1 is switched from the closed state to the first open state or the second open state, the operation unit 14 and the first display unit 7 are exposed, and the light source illuminating the operation unit 14 or the light source illuminating the first display unit 7 It turns on. If it is not operated for a predetermined time, the light source is turned off. When the main body unit 1 is closed from the opened state, both of the light sources for illuminating the operation unit 14 and the first display unit 7 are turned off to reduce power consumption. Further, when an incoming call is received when the main body unit 1 is in the closed state, the other party information is displayed on the second display unit 8. When the user places the main unit 1 in the first open state to perform an incoming call operation, the information displayed on the second display unit 8 is not displayed and is instead displayed on the first display unit 7, etc. According to one aspect, various display methods are controlled.

The cable 32 electrically connects the first printed circuit board 12 and the second printed circuit board 18. Under control of the control unit 26, transmission and reception of signals for causing the receiver 5 and the speaker 6 to output sound, and signals for causing the first display unit 7 to display photographed images by the first camera unit 9 and the second camera unit 15 are It will be. The tube member 33 is fixed to the cable 32 by tape 35 (only one end side is shown in FIG. 2) at both ends. Since the tube member 33 expands and contracts, the tube member 33 is fixed to prevent the tube member 33 from moving arbitrarily with respect to the cable 32 when assembled to the main body 1.

Next, the connecting portion 4 will be described in detail with reference to FIG. 2, FIG. 4, FIG. 5 (a) and (b). First, description will be made with reference to FIG. The second hinge 29 housed in the connecting portion 4 includes the pivot shaft member 41, the holding member 42, the cam member 43, the first spring member 44, the cylindrical member 45, the flat member 46, and the retaining ring 47. , A moving member 48, and a second spring member 49. An attachment member (bearing member or movement control unit) 50 which is non-rotatably attached to the lower housing 3 is disposed adjacent to the second hinge 29.

The rotating shaft member 41 is formed to be orthogonal to the small diameter portion 51, the groove 52 formed in the small diameter portion 51, the large diameter portion 53 having a diameter larger than that of the small diameter portion 51, and the large diameter portion 53. Arm 54, a first screw hole 57 and a second screw hole 58 formed in the arm 54, and a first through hole 59 passing through the small diameter portion 51 and the large diameter portion 53. .

The large diameter portion 53 has a notch surface 60. The notch surface 60 is shown in FIG. The first screw hole 57 and the second screw hole 58 are fixed to the upper housing 2 by screws 55 and 56 shown in FIG. The large diameter portion 53 is formed between the small diameter portion 51 and the arm portion 54.

The holding member 42 rotatably supports and holds the small diameter portion 51 of the rotation shaft member 41. The second through hole 61 and the third through hole 62, and the accommodation portion 63 which accommodates and holds the moving member 48. , A third screw portion 64, a first protrusion 65, and a second protrusion 66. The small diameter portion 51 passed through the second through hole 61 includes a cam member 43 attached so as to rotate together with the small diameter portion 51, a first spring member 44, a cylindrical member 45, and a flat member 46; Is attached. Thereafter, the large diameter portion 53 contacts the holding member 42, and the pivot shaft member 41 is positioned with respect to the holding member 42 so that the tip of the small diameter portion 51 does not penetrate the third through hole 62 of the holding member 42. Ru.

The retaining ring 47 is attached to the groove 52, and the pivot shaft member 41 is pivotably attached to the holding member 42. The pivot shaft member 41 is held so as not to come off the holding member 42.

The first spring member 44 is configured by stacking a plurality of disc springs in series.

The cylindrical member 45 is provided to surround the first spring member 44. The cylindrical member 45 surrounds the first spring member 44 to prevent dust from entering the first spring member 44 during assembly. Further, a force acts on the holding member 42 such that the pivoting shaft member 41 comes off, preventing extreme deformation such that all the first spring members 44 formed of a plurality of disc springs become flat. (The first spring member 44 is prevented from being permanently deformed).

The cam member 43 is a member that generates a click when the rotating shaft member 41 rotates. For this purpose, the small diameter portion 51 is provided movably in the thrust direction. An uneven first uneven surface 67 is formed on one side, and the opposite side of the first uneven surface 67 is biased by the first spring member 44. An uneven second uneven surface 68 is also formed on the holding member 42 facing the first uneven surface 67. When the cam member 43 is rotated together with the rotation shaft member 41 from the state where the convex surface of the first uneven surface 67 and the concave surface of the second uneven surface 68 face each other, the convex surface of the first uneven surface 67 is the second uneven surface 68 The convex surface of the first uneven surface 67 and the convex surface of the second uneven surface 68 face each other. At the time of escape, the deflection of the first spring member 44 increases and a click occurs. When the convex surface of the first uneven surface 67 faces the concave surface of the second uneven surface 68 from the state where the convex surface of the first uneven surface 67 faces the convex surface of the second uneven surface 68, the deflection of the first spring member 44 Decreases and generates clicks.

That is, when the rotation shaft member 41 is rotated, the torque required for the rotation can be obtained as a click when it changes rapidly. The position where the click occurs is configured to occur when the transition from the closed state to the second open state is started and when the transition to the second open state is completed. When the user moves from the closed state to the second open state, it is obtained as a click at the start of the transition and at the completion of the transition. In addition, when the transition from the second open state to the closed state is started and the transition is completed, the click feeling is obtained.

The flat member 46 is provided to prevent the corner 44A of the disc spring constituting the first spring member 44 from coming into direct contact with the retaining ring 47. Further, the small diameter portion 51 is inserted into the hole 69.

Although the corner 44A of the disc spring is circular, since the snap ring 47 has the cut-out opening 70, the corner 44A of the disc spring falls off at the opening 70 and is inclined, so that a predetermined bending Avoid getting rid of it.

Here, with reference to FIGS. 5A and 5B, the operation of the flat member 46 will be described. As shown in FIG. 5A, since the flat member 46 is provided, the corner portion 44A on the inner diameter side of the disc spring disposed closest to the snap ring 47 in the first spring member 44 has an entire circumference of the flat member 46. It abuts on the first flat surface 46A. Even when the corner portion 44B on the outer diameter side of the disc spring is disposed closest to the retaining ring 47, the entire periphery of the corner portion 44A abuts on the first flat surface 46A of the flat member 46. On the other hand, as shown in FIG. 5B, without the flat member 46, a part of the corner portion 44A on the inner diameter side of the disc spring disposed closest to the snap ring 47 in the first spring member 44 is the snap ring 47. Fall into the opening 70 of the Therefore, as shown in FIG. 5 (b), the disc spring is inclined. When the disc spring is inclined, the plurality of stacked first spring members 44 do not generate a predetermined deflection. Therefore, since the cam member 43 is not biased with a predetermined load, the cam member 43 which rotates together with the pivot shaft member 41 does not generate a predetermined sliding torque or a desired click.

Therefore, since the second hinge 29 is provided with the flat member 46, the first spring member 44 generates a predetermined deflection so that a stable torque can be generated in the pivot shaft member 41, and so on. Miniaturization is attempted while minimizing variations without sacrificing.

If the biasing force generated by the first spring member 44 is received perpendicularly to the surface of the retaining ring 47 on the first spring member 44 side, the first spring member 44 generates a predetermined deflection. For example, between the first spring member 44 and the retaining ring 47, a part whose side surface facing the first spring member 44 and the side surface facing the retaining ring 47 are both parallel to the retaining ring 47 You may add it.

Retaining ring 47, which is a back surface of the first flat surface 46A of the flat member 46 and the back surface of the first flat surface 46A and is in contact with the second flat surface 46B parallel to the first flat surface 46A An end surface 52A of the second spring member 44 and a surface opposite to the first uneven surface 67 of the cam member 43 are all parallel and perpendicular to the axial center b of the pivot shaft member 41. . Therefore, since the corner portion 44A on the inner diameter side of the disc spring disposed closest to the retaining ring 47 in the first spring member 44 abuts on the first flat surface 46A, the reaction force of the first spring member 44 is a small diameter portion It can act in the thrust direction of 51. Therefore, the biasing force of the first spring member 44 acts on the opposite surface of the end face 52A and the first uneven surface 67 perpendicularly (parallel to the axis b).

At least the back surface of the first uneven surface 67 and the end surface 52A are perpendicular to the axial center b, and the back surfaces of the first flat surface 46A and the first uneven surface 67 are corner portions of the first spring member 44. If a component for transmitting the biasing force of the spring is interposed between the flat member 46 and the retaining ring 47, the first spring member 44 generates a predetermined biasing force and rotates The shaft member 41 rotates with a predetermined torque, and the cam member 43 generates a desired click.

As described above, since the corner portion 44A on the inner diameter side of the disc spring disposed closest to the retaining ring 47 in the first spring member 44 must be applied to the flat member 46, the hole for the outer diameter of the small diameter portion 51 The gap (backlash) with 69 (see FIG. 4) must be set in consideration of the assemblability. That is, even if the backlash becomes maximum, it may be appropriately set so as to reliably abut the corner portion 44A on the inner diameter side of the disc spring disposed closest to the retaining ring 47 in the first spring member 44.

When the retaining ring 47 is attached to the groove 52 while the opening 70 deforms, the first spring member 44 bends by a predetermined amount to bias the cam 43 toward the holding member 42.

That is, when the holding member 42 is attached to the groove portion 52 while the opening 70 of the snap ring 47 is expanded, the holding member 42 holds the cam member 43, the first spring member 44, the snap ring 47, and the flat member 46 between them. Hold in place. It is not a so-called cantilevered state, but is in the both end supported state. Thus, the holding member 42 can increase the holding length L1 for holding the small diameter portion 51 (the length from the back surface of the first uneven surface 67 to the end surface 52A shown in FIG. 2). The swing of the rotating shaft member 41 with respect to 42 is reduced.

In a state where the snap ring 47 is attached to the groove 52, the large diameter portion 53 is urged to abut against the entrance of the second through hole 61 by the biasing force of the first spring member 44, and the flat member 46 is in contact with the snap ring 47. Since the biasing portion abuts, the small diameter portion 51 is attached to the holding member 42 in a state in which the fine movement in the thrust direction of the rotation shaft member 41 does not occur (there is no backlash).

The moving member 48 has a protrusion 72, a leg 73, and a cylindrical portion 74. The cylindrical portion 74 is inserted into the second spring member (coil spring) 49 and accommodated in the accommodating portion 63 of the holding member 42. The protrusion 72 is formed at the tip of the direction biased by the second spring member 49. In the state where the moving member 48 is accommodated in the accommodating portion 63, the second spring member 49 urges the movable member 48 in the direction of the arrow C shown in FIG. The protruding protrusion 72 is adjacent to the second protrusion 66 formed at the inlet of the housing 63.

The bearing member 50 is provided to straddle the lower housing 3 and the connecting portion 4, is fixed to the lower housing 3, and is rotatably attached to the connecting portion 4. The bearing member 50 has a fourth through hole 75 and a hook 76 formed on the front end side, and the hook 76 contacts the leg 73 when the main body 1 is in the first open state. The moving member 48 is moved in the direction opposite to the arrow C direction shown in FIG.

Next, the connecting portion 4 will be described with reference to FIG. A substantially cylindrical first hinge mounting portion 77 is provided at an end (the left end in FIG. 6) at one end of the lower housing 3 (the side on which the connecting portion 4 is mounted), and a substantially cylindrical guide at a substantially central portion The portion 78 is formed.

The connecting portion 4 includes a first holding portion 79, a second holding portion 80, and a connection portion 81 connecting the first holding portion 79 and the second holding portion 80. The first holding portion 79 is disposed between the first hinge mounting portion 77 and the guide portion 78.

The connection portion 81 is disposed outside the guide portion 78, and the first holding portion 79 and the second holding portion 80 are formed so as to sandwich the guide portion 78 from the outside. And a second hinge mounting portion 82 in which the second hinge 29 is mounted inside the connecting portion 81. The second hinge mounting portion 82 has the third screw portion 64 of the second hinge 29 at the head with respect to the connecting portion 4 and from the upper housing 2 side to the lower housing 3 side when the main body portion 1 is in the closed state. Assembled in the direction. After the second hinge 29 is accommodated in the connecting portion 4, the screw 83 is screwed and fixed to the third screw portion 64.

The first hinge 28 has a first fixing portion 28A held non-rotatably by the first hinge mounting portion 77 and a second fixing portion 28B held non-rotatably by the first holding portion 79. When the upper housing 2 is rotated relative to the lower housing 3 in the direction of arrow A around the axis a shown in FIG. 6, the second fixed portion 28B is rotated relative to the first fixed portion 28A, A desired sliding torque and click can be obtained by the built-in click generation unit (not shown) and the torque generation unit (not shown).

Since the reference numerals shown in FIGS. 7 to 9 are the same as the reference numerals shown in FIG. 6, the explanation of the reference numerals in FIGS. 7 to 9 will be omitted. In addition, although the cable 32 is comprised from multiple pieces, in FIG. 7 thru | or FIG. 9, it has shown collectively as one cable.

Next, the cable 32 will be described with reference to FIGS. 2 and 10A and 10B. In FIG. 2, the cable 32 is composed of a plurality of cables. Although not shown, one cable 32 includes a plurality of center conductors, a first insulating layer provided outside the center conductors, an outer conductor provided outside the first insulating layer, and an outer of the outer conductors. It is a coaxial thin line which consists of the provided 2nd insulating layer. The plurality of cables 32 are made of fibers made of polyester or the like, and then passed through a hollow tubular member 33.

The tube member 33 is formed of a fiber material so that the cross-sectional shape can be easily deformed and both the surface and the inner surface have low friction. For example, the case where the pipe member 33 is formed of a rubber material will be described. When the main body 1 is opened and closed, the tube 33 rubs with other surrounding components (such as the inner surface of the connecting portion 4 and the first through holes 59 of the pivot shaft member 41), so that wear easily occurs. At this time, since the surface of the rubber material has a large frictional resistance, abrasion occurs when it is rubbed, and the hole is opened. Therefore, generally, a protective tape may be wound around a rubber pipe member. As a result, cost increases are likely to occur.

The tube member 33 is disposed in the first through hole 59 with the plurality of cables 32 passing through the hollow portion. One end side of the pipe member 33 is guided into the upper housing 2 after escaping from the first through hole 59. The other end side of the tube member 33 is bent to about 90 degrees after being released from the first through hole 59, and is guided to the lower housing 3 side through the fourth through hole 75 of the bearing member 50. If, for example, the plurality of cables 32 are bundled with an adhesive tape or the like in the vicinity of the portion where the plurality of cables 32 are bent at 90 degrees, the bundled plurality of cables 32 becomes difficult to bend, and the result is In particular, the curvature R to be formed is increased. Even when the curvature R is large, the distance L2 (see FIG. 2) from the first through hole 59 to the inner surface 4A of the connecting portion 4 is also large in order to wire the plurality of cables 32 bundled in the connecting portion 4 As a result, it is necessary to make the connecting portion 4 and the entire main portion 1 larger.

In the present embodiment, a plurality of cables 32 are only passed through the hollow portion of the tube member 33 without being bundled. Therefore, the plurality of cables 32 are arranged in a substantially circular shape and run in parallel in the first through holes 59, as shown in FIG. 10 (a). The tube members 33 are also arranged linearly. Here, assuming that the diameter of the pipe member 33 is D, the diameter of the pipe member 33 is larger than the distance L2 from the first through hole 59 to the inner surface 4A of the connecting portion 4 (D> L2). . Further, immediately after the plurality of cables 32 escape from the first through hole 59, a space of a distance L2 from the first through hole 59 to the inner surface 4A of the connecting portion 4 is passed, as shown in FIG. Becomes substantially elliptical. The tube member 33 is also deformed into a substantially elliptical shape. The short axis side of the tube member 33 is substantially equal to the distance L2.

As described above, since the plurality of cables 32 are provided in the tubular member 33 whose cross section is deformable and bent at 90 degrees and arranged in a space narrower than the diameter of the tubular member 33, the curvature generated when bent is It can be made smaller. Therefore, since the wiring space can be reduced, the enlargement of the main body 1 can be avoided.

Next, the operation of the openable mobile phone according to the embodiment of the present invention will be described with reference to FIGS. 1 (a) to 1 (c). The user selects the closed state (FIG. 1 (a)), the first open state (FIG. 1 (b)), and the second open state (FIG. 1 (c)) in accordance with the use mode.

When the main unit 1 is powered on, the main unit 1 starts a reception standby operation. By operating the operation unit 14, it is possible to switch to the camera mode or the TV reception mode.

In the camera mode, the mode is switched by activation of the second camera unit 15. When the second camera unit 15 is activated, the photographed image of the second camera unit 15 can be displayed on the first display unit 7, and when the photographed image is stored, it can be recorded in the information storage unit 25. .

In the TV reception mode, when the TV broadcast is received, the first display unit 7 can view the TV. Since the TV image is a landscape screen, it is desirable to view it on a landscape screen. In this case, the upper case 2 is opened relative to the lower case 3 in the direction of the arrow B centering on the axis b shown in FIG. 1C, and the main body unit 1 is brought into the second open state. When viewed from the side, the first display unit 7 can be viewed as a horizontally long screen, which is suitable for TV viewing.

When an incoming call is received under each mode, a ringing tone is output from the speaker 6 to notify an incoming call. At this time, the upper case 2 is pivoted in the direction of arrow A centering on the axis a shown in FIG. 1B to place the main body 1 in the first open state, and a predetermined operation can be performed. The voice of the user is output from the microphone 13.

When the call is ended, the mode just before the reception resumes.

When carrying, the closed state shown in FIG. 1 (a) is preferable.

Next, an operation when the main body unit 1 is opened and closed will be described using FIG. In FIG. 6, since the main body 1 is in the closed state, the hooking portion 76 of the bearing member 50 abuts on the leg 73 of the moving member 48 to move the moving member 48 in the direction opposite to the arrow C direction shown in FIG. It is moved (in FIG. 6, in the depth direction in the drawing). In FIG. 6, the moving member 48 is shown being buried in the housing portion 63. Since the projecting portion 72 of the moving member 48 does not face the notch surface 60 of the large diameter portion 53 of the rotating shaft member 41, the rotating shaft member 41 has an arrow B shown in FIG. It can be turned in the direction.

Next, using FIG. 7 and FIG. 8, from the closed state shown in FIG. 1 (a), the upper case 2 is rotated in the direction of arrow B centering on the axial center b with respect to the lower case 3 The operation will be described when it is moved to the second open state shown in FIG. 1 (c). FIG. 7 shows a state (second open state) in which the turning shaft member 41 is turned about 170 degrees in the arrow B direction about the axis b from the state (closed state) of FIG. The large diameter portion 53 of the rotating shaft member 41 passes through the tip end side of the projecting portion 72 of the moving member 48 to be in the second open state. The notch surface 60 abuts on the first projection 65 formed on the holding member 42, so that only a predetermined amount of angle (170 degrees in the present embodiment) can be rotated. Further, in the second open state, the large diameter portion 53 covers a part (head portion) of the protrusion 72 of the moving member 48.

That is, the hooking portion 76 of the bearing member 50 abuts on the leg portion 73 of the moving member 48, and the bearing member 50 opposes the biasing force of the second spring member 49 in the direction opposite to the arrow C of the moving member 48. , And pulls the projection 72 into the housing 63. The large diameter portion 53 of the pivot shaft member 41 is configured to cover the tip of the protruding portion 72 of the moving member 48 on the arrow C side.

FIG. 8 is a partially enlarged view of FIG. In FIG. 8, in the second open state, the large diameter portion 53 covers a part (head portion) of the projecting portion 72 of the moving member 48, and the covered portion is indicated by a hatched portion 72A.

Next, the operation of the bearing member 50 will be described with reference to FIG. 9 does not turn the upper housing 2 with respect to the lower housing 3 in the arrow B direction about the axis b from the closed state shown in FIG. It is the same as the state rotated in the arrow A direction centering on the axial center a, and the lower housing 3 rotated in the opposite direction to the arrow A direction centering on the axial center a with respect to the upper housing 2 Is shown.

The bearing member 50 is non-rotatably held by the guide portion 78 of the lower housing 3 and is rotatably held by the second holding portion 80 of the connecting portion 4. On the other hand, when the upper housing 2 is rotated about the axis a in the direction of arrow A by a predetermined angle, the bearing member 50 is in the direction opposite to the direction of arrow A about the axis a with respect to the connecting portion 4. Rotate by an angle. As a result, the hook portion 76 of the bearing member 50 separates from the leg portion 73. The moving member 48 separated from the bearing member 50 is moved in the direction in which the protrusion 72 protrudes from the holding member 42 by the biasing of the second spring member 49. Since the projecting portion 72 after the projection abuts on the notch surface 60, the upper housing 2 does not rotate in the arrow B direction about the axial center b.

That is, the bearing member 50 controls the position of the moving member 48 against the biasing force of the second spring member 49 in accordance with the housing mode of the main body 1. Further, since the protrusion 72 is adjacent to the second protrusion 66, when the upper housing 2 is intentionally or unintentionally pivoted around the axis b in the direction opposite to the arrow B direction, the protrusion 72 Is in contact with both the notch surface 60 and the second projection 66. At this time, since the projecting portion 72 is broken when it is in contact with a large force, the projecting portion 72 is in contact with the second projecting portion 66 so that the projecting portion 72 is not broken even when receiving a force from the notch surface 60. There is.

That is, in a state where the projecting portion 72 protrudes from the housing portion 63, when receiving a force from the notched surface 60, the projecting portion 72 is in a so-called cantilever state, and a bending moment is generated. In order to prevent breakage even if this bending moment acts, it is preferable to use a material having a large movable member 48 or a large allowable stress, but on the other hand, it causes an increase in size and cost.

Therefore, by making the second moment the second projection 66 contact the surface opposite to the surface receiving the force of the moving member 48, it is possible to prevent the bending moment from being generated. doing. That is, the force applied to the protrusion 72 replaces the force compressed from the force to be bent. As the material that can withstand the compressive force is abundant, the moving member 48 can be made of a general-purpose material.

Next, the third open state will be described using FIG. 1 (d). When the user performs an erroneous operation of rotating the upper housing 2 relative to the lower housing 3 in the direction of the arrow A with respect to the lower housing 3 from the second open state shown in FIG. The hooking portion 76 of the bearing member 50 is separated from the leg portion 73 of the moving member 48. When moving away from each other, the moving member 48 tries to move in the direction of the arrow C by urging of the second spring member 49, but a part (head portion) of the moving member 48 is covered by the large diameter portion 53. , Can not move in the arrow C direction. If the leading end of the moving member 48 is not covered by the large diameter portion 53, the moving member 48 moves in the arrow C direction. As a mode of the main body 1, the upper housing 2 is rotated with respect to the lower housing 3 in the direction of arrow A around the axis a and in the direction of arrow B around the axis b, as shown in FIG. The state of the main body 1 shown in (d) will be referred to as a third open state. In the third open state, the first display unit 7 does not face the user, so the display information displayed on the display unit 7 can not be viewed. Therefore, in order to eliminate the third open state, the user need only rotate the upper housing 2 to the opposite side in either the A direction or the B direction. If it is configured to rotate only in one of the A direction and the B direction, a force may be applied in a direction in which the user can not turn erroneously, and the main body 1 may be broken.

As in the present embodiment, in the third open state shown in FIG. 1D, the moving member 48 is covered by the large diameter portion 53 and can not move in the direction in which the moving member 48 protrudes. From the third open state, the upper housing 2 is pivoted about the axis a in the direction opposite to the arrow A direction or in the direction opposite to the arrow B direction about the axis b. For example, the mode can be changed to either one of the first open state and the second open state. In the first open state, the moving member 50 moves and the projection 72 protrudes, and the projection 72 after projection abuts on the notch surface 60 as described above. Therefore, the upper housing 2 can not be rotated in the arrow B direction about the axial center b. Therefore, the second open state does not return to the third open state.

As described above, since the holding member 42 is configured to hold the small diameter portion 51 of the pivot shaft member 41 at the longest distance L1 in the connecting portion 4, the rattling with respect to the pivot shaft member 41 should be reduced. Can. Even when a force is applied from the outside, since the long distance L1 is held, the increase of rattling can be reduced.

Further, in the first open state, the moving member 48 protrudes and contacts the large diameter portion 53, so the upper housing 2 does not rotate even if it is rotated in the arrow B direction about the axis b. You can do so. Moreover, when the upper case 2 is to be rotated in the direction of arrow B in the closed state, this can be easily performed. In such a main body portion 1, if the user accidentally enters the third open state, it can be easily transformed into either the first open state or the second open state, and the first open state In this case, it is possible to provide a user-friendly terminal, such as preventing the mode from being changed to the third open state.

That is, since the moving member 48 interlocked with the mode state of the main body 1 is provided in the second hinge 29 so as not to change from the first open state to the third open state, the upper housing is in the first open state. When placing a call by placing the head on 2, the upper case is prevented from rotating against the user's intention.

Further, since the cables 32 for electrically connecting the upper housing 2 and the lower housing 3 are wired to the pipe member 33 whose cross section can be deformed, the wiring space can be saved, and the main body 1 can be obtained. Avoid the upsizing of

When the pipe member 33 is not provided, the second insulating layer directly contacts the first through hole 59 of the second hinge 29. When the pivot shaft member 41 pivots, the first through hole 59 and the second insulating layer rub against each other, and sometimes the outer conductor may be exposed. In general, the second hinge 29 is formed of a metal material because high rigidity is required. Therefore, when the outer conductor is exposed, the rotary shaft member 41 and the outer conductor may short-circuit and may be double-fed as a signal with the signal to the central conductor. In order to avoid this, it is preferable to form a second insulating layer having a desired thickness, but on the other hand, the cable 32 becomes difficult to bend. As a result, the inner diameter and L2 of the first through hole 59 must be increased. Therefore, in order to miniaturize the second hinge 29 by saving space and reducing the diameter of the first through hole 59, the cable 32 is preferably inserted into the pipe member 33 without being bundled with a tape.

Further, in the present embodiment, when the main body 1 is in the closed state, the bearing member 50 is in contact with the moving member 48, and the moving member 48 is controlled to move in the direction opposite to the arrow C direction. Absent. A component fixed to the lower housing 3 or a part of the lower housing 3 may control the position of the moving member 48 as an alternative to the bearing member 50.

Further, the second spring member 49 of the present embodiment is formed of a compression spring, and when the main body 1 is in the closed state, the moving member 48 is moved in the direction opposite to the arrow C against the spring force of the second spring member 49. It was made to move, but it is not necessarily this limitation. For example, the second spring member 49 is constituted by a tension spring, and the force of the tension spring pulls the protrusion 72 in the direction opposite to the arrow C direction. When the main body 1 is in the closed state or in the second open state, a part of the bearing member 50 or the lower housing 3 may move the moving member 48 in the arrow C direction against the spring force.

Further, although the moving member 48 is configured to perform so-called translational movement, this is not necessarily the case. For example, a rotation shaft is provided, is not in contact with the rotation shaft member in the first position, and is in contact with the rotation shaft member in the second position to restrict rotation, rotation about the rotation shaft You may make it move by exercise.

In addition, although the circumference of the retaining ring 47 is not described in detail, for example, when the user accidentally drops the main body 1, the impact force is such that the retaining ring 47 falls out of the groove 52. Works. Assuming such a situation, a rib or the like facing the outer periphery of the retaining ring 47 may be provided in the connecting portion 4 so that the opening 70 of the retaining ring 41 does not spread.

Although the above-mentioned corner portions are all illustrated at right angles, the same edge is brought into contact with the first flat surface 46A even if a curved surface or a flat surface is given in part production. It is also good.

Moreover, although the large diameter part 53 was demonstrated as a structure integral with the rotational axis member, you may mount and comprise another member.

Summarizing the above, the flat member 46 constituting the second hinge is the first flat surface 46A that abuts the closest corner of the first spring member 44 and the back surface of the first flat surface 46A, and the retaining ring 47 And the first spring member 44 is in contact with the first flat surface 46A, and the second flat surface 46B is in contact with the flat surface of the retaining ring 47. It is a thing. Further, the holding member 42 holds the pivoting shaft member 41 so as to sandwich the cam member 43, the first spring member 44, the retaining ring 47, and the flat member 46 therebetween.

According to the above-described configuration, the removable retaining ring is used, and since the first spring member 44 is brought into contact with the flat first flat surface 46A, the first spring member 44 can be assembled with a simple operation. A constant deflection can be stably applied to the spring member 44. In addition, since the disassembling can be performed simply by removing the retaining ring 47, the maintainability can be improved, the disassembling time at the time of disposal can be shortened, and the classification of materials can be facilitated. Furthermore, since the small diameter portion 51 can be held as long as possible, the inclination of the pivot shaft member 41 with respect to the holding member 42 can be reduced.

In addition, since the second hinge is provided in the opening / closing portable terminal, the inclination of the upper housing 2 and the lower housing 3 constituting the opening / closing portable terminal can be reduced.

In the second hinge, when the moving member 48 is in the first position, the moving member 48 abuts on the rotating shaft member 41 to restrict the rotation of the rotating shaft member 41, and the moving member 48 When in the 2 position, the contact between the moving member 48 and the rotating shaft member 41 is released, and the rotation restriction of the rotating shaft member 41 is released, and a part of the rotating shaft member 41 is a moving member It is characterized in that the first position side tip of 48 is covered.

According to the above configuration, when the moving member 48 tries to move to the first position due to a malfunction even if the rotating shaft member 41 is immobile from the state where the moving member 48 is at the second position, the moving member 48 Can block the movement of

In addition, since the second hinge is provided to the openable portable terminal, from one aspect of the openable portable terminal in which the moving member is at the second position, the moving member is erroneously operated even if the pivot shaft member 41 is immobile When 48 attempts to move to the first position, movement of the moving member 48 can be blocked.

Further, from the closed state, the upper housing 2 is rotatably coupled to the lower housing 3 in the direction of the arrow A with respect to the lower housing 3 and the upper housing relative to the lower housing 3 And a connecting portion 4 rotatably connected in the direction of arrow B around the axis b, and the connecting portion 4 is a rotating shaft member 41 connected to the upper housing 2, and a rotating shaft member 41 and a movable member 48 disposed in the connecting portion 4 and movable from the first position to the second position, and a movable member from the first position to the second position The second spring member 49 which biases 48 and a portion of the lower housing 3 are formed or attached to the lower housing 3 and controlled to change the position of the moving member 48 according to the aspect of the main body 1 And the moving member 48 is in contact with the pivot shaft member 41 at one of the first position and the second position. The rotation of the moving shaft member 41 is restricted, and at the other position of the first position and the second position, the contact with the rotating shaft member 41 is canceled and the rotation of the rotating shaft member 41 is permitted. The movement control unit 50 contacts the moving member 48 when rotating the upper housing 2 with respect to the lower housing 3 in the direction of arrow A around the axial center a or the second spring member. It is characterized in that it is configured to control the position of the moving member 48 against the biasing force by 49.

According to the above configuration, the movement control unit 50 controls the position of the moving member 48 interlockingly with the aspect of the casing constituting the main body unit 1, so that the user can center the upper casing 2 from the closed state. The rotation of the upper case 2 can be restricted only by changing it in the direction of the arrow A centering on a, and the rotation restriction of the upper case 2 can be released only by changing (returning) to the superimposed state. In addition, after changing the upper case 2 in the direction of arrow B around the axis b, it has been turned to the direction of arrow A around the axis a and is in the non-normal state (third open state) In this case, by rotating the upper housing about the axis a to the opposite side in the direction of arrow A or to the opposite side to the direction of arrow B about the axis b, the normal state first open state or second open state) Can recover.

A pivoting device according to the present invention comprises a pivoting shaft member, a holding member for rotatably holding the pivoting shaft member, and a movement which is held by the holding member and is movable from a first position to a second position And when the movable member is in the first position, the movable member abuts against the rotary shaft member to restrict rotation of the rotary shaft member, and the movable member When in the two positions, the contact between the moving member and the pivoting shaft member is canceled, and the pivoting regulation of the pivoting shaft member is released, and a part of the pivoting shaft member is moved by the movement The tip on the first position side of the member is covered.

According to the above configuration, when the moving member is in the first position, rotation of the turning shaft member can be restricted, and when the moving member is in the second position, turning of the turning shaft member is permitted. Can. Moreover, even when the rotating shaft member is immobile from the state where the moving member is at the second position, when the moving member tries to move to the first position due to a malfunction or erroneous operation, the movement of the moving member can be blocked. . In addition, when the moving member is in the first position and the contact between the moving member and the rotating shaft member is eliminated, the moving member is moved by the biasing force of the spring member and the rotating shaft member is rotated. It is possible to prevent the occurrence of regulated situations.

An openable-closable portable terminal according to the present invention is characterized by comprising the above-described pivoting device.
