Description

  The present invention relates to a portable information device provided with a movable member that moves back and forth in conjunction with a turning operation of a housing.

  For example, in portable information equipment such as a convertible tablet personal computer (convertible PC) configured such that the display casing can be reversed from the 0-degree position to the 360-degree position with respect to the main body casing, the thickness of the casing has recently been reduced. Is progressing rapidly.

  Usually, a keyboard device having a plurality of key tops elastically supported so as to move up and down is mounted on a main body casing of this type of portable information device. In order to ensure high operability in such a keyboard device, it is necessary to ensure a certain amount of key strokes. Therefore, in order to prevent the display from interfering with the keyboard device on the top surface of the main body housing when the display housing is closed, it is necessary to secure a certain thickness on the keyboard device itself. It was a barrier to thinning.

  For example, in Patent Document 1, in a portable information device such as a notebook PC, a pressing protrusion is projected on the inner surface of a display housing, and a pressing member connected to each key top is connected to a keyboard device on the body housing side. The provided arrangement is disclosed. In this configuration, when the display housing is closed, the protrusions press and push down the pressing member, so that each key top is also pressed down. This prevents interference between the display and the key top, thereby reducing the thickness.

  By the way, in the convertible PC as described above, when it is transformed into a usage form as a tablet PC, the surface (front surface) provided with the keyboard device of the main body casing is the back side in this usage form. However, in the configuration of Patent Document 1, the key top is pushed down only when the display housing is closed. Therefore, the key top cannot be pushed down and stored at the 360 degree position of the convertible PC, for example. Therefore, when the tablet is placed on a desk or the like and used as a tablet PC, the key top becomes an obstacle and lacks stability, and the key top may be damaged or damaged. Such a problem also occurs in various function switches other than the key top.

  Furthermore, in the convertible PC as described above, since the front surface of the main body housing provided with the keyboard device is the back surface when the tablet PC is used, there is a demand for providing a leg portion such as a rubber leg on this surface. is there. However, when the legs are provided on the surface as described above, the leg portions can be effectively used when the tablet type PC is used, but thin when the notebook PC is used or when the display housing is closed at the 0 degree position. And hindering the appearance and quality of appearance.

  The present invention has been made in consideration of the above-described problems of the prior art, and an object thereof is to provide a portable information device that can be thinned while ensuring the functionality and appearance quality of the product. .

  In the portable information device according to the present invention, a main body housing having an operation means on the surface and a display housing having a display on the surface are rotatably connected by a hinge mechanism, and the main body housing and the display housing are connected. The surface of the main body housing and the display housing face each other through the 180 degree position where the surfaces of the main body housing and the display housing face in the same direction and are parallel to each other. A portable information device capable of rotating to a 360-degree position, a first movable member that advances and retreats from the outer surface of the main body case, a second movable member that advances and retreats from the outer surface of the main body case, and the hinge A slide member that moves by a movement amount according to a rotation angle of the main body casing and the display casing by a mechanism, and interlocked with a rotation operation of the main body casing and the display casing. Characterized in that it comprises a serial first movable member and the link mechanism for advancing and retracting operation of the second movable member.

  According to such a configuration, the first and second movable members advance and retreat according to the amount of movement by the slide member moving within a movement range interlocked with the rotation operation of the display housing by the hinge mechanism. As a result, the first and second movable members can be moved back and forth to a position suitable for the usage according to the rotation angle of the display housing, and the thickness and thickness can be reduced while ensuring the functionality and appearance quality of the product. It becomes possible to plan.

  The slide member moves in one direction in conjunction with a rotational movement of the display housing from the 0 degree position to a first angle position smaller than the 180 degree position with respect to the main body housing. It moves in the other direction opposite to the one direction in conjunction with the turning operation from the one angle position toward the 0 degree position, and further from the second angle position from the second angle position larger than the first angle position. While moving in the other direction in conjunction with the pivoting operation toward the large third angle position, it moves in the one direction in conjunction with the pivoting operation from the third angle position toward the second angular position. And the slide member moves from the second angular position to the third angular position with respect to the amount of movement of the display housing in the other direction in the rotational movement from the first angular position to the 0 degree position. Rotating motion toward The may be a movement amount larger configuration to other directions. In this case, the first movable member can be moved back and forth within a small movement amount range, while the second movable member can be moved back and forth only within the difference between the two movement amounts.

  The first movable member is a key top of a keyboard device that is the operation means provided on the surface of the main body casing, and the second movable member is a leg portion provided on the surface of the main body casing. It may be configured. If it does so, a key top and a leg part can be set to a desired advance / retreat position according to the rotation angle of a display housing | casing. In particular, when the portable information device is a convertible PC, for example, the key top is used in the usage form of the notebook PC from the first angle position (for example, 70 degree position) to the second angle position (for example, 180 degree position). On the other hand, the protruding use position can be set, while the 0-degree position and the 360-degree position can be set to a pressed position where the key top is pressed down. Further, for example, the leg portion can be set to the buried position in the usage form of the notebook type PC from the first angular position (for example, 70 degree position) to the second angular position (for example, 180 degree position). The leg portion can be used as the protruding position at the 360-degree position, which is the use form.

  The first movable member is a key top of a keyboard device that is the operation means provided on the surface of the main body casing, and the second movable member is a leg portion provided on the surface of the main body casing. And the key top is in a pressed position pushed down from the outer surface of the main body housing at least at the 0 degree position and the 360 degree position, while at least in the range from the first angular position to the second angular position. The use position protrudes from the outer surface of the main body casing, and the leg portion is a buried position where the leg portion is submerged from the outer surface of the main body casing in the range of at least the 0 degree position and the first angular position to the second angular position. On the other hand, the structure which becomes the protrusion position which protruded from the outer surface of the said main body housing | casing in the range of the said 360 degree position from the said 3rd angle position may be sufficient.

  When the display casing performs a rotation operation from the first angular position toward the 0 degree position and the slide member moves in the other direction, the key top is moved to the pressed position by the movement of the slide member. On the other hand, the leg may be configured to be maintained at the buried position.

  When the slide housing moves in the other direction by rotating the display housing from the second angle position toward a predetermined angle position smaller than the third angle position, the movement of the slide member causes the While the key top is in the depressed position, the leg portion is maintained in the buried position, and the display housing performs a pivoting operation from the predetermined angular position to the third angular position so that the slide member is in the other position. In the case of moving in the direction, the leg portion may be brought into the protruding position by the movement of the slide member, while the key top may be maintained in the pressed position.

  The leg protrudes from the outer surface of the main body housing by pressing the support member in conjunction with the movement of the slide member and a support member that supports the leg portion so as to be able to advance and retreat from the outer surface of the main body housing. A structure may be provided that includes a push-up member to be moved, and a spring member that is interposed between the push-up member and the slide member and that displaces the push-up member along a pressing direction with respect to the support member. Then, for example, when the display housing is rotated in a state where the top of the leg is pressed by an external force, the movement of the slide member can be absorbed by the spring member, which is excessive in each element of the hinge mechanism and the link mechanism. Can be avoided.

  The link mechanism may include a second slide member that moves in conjunction with the movement of the slide member, and the push-up member may be connected to the second slide member via the spring member. Good. Then, the operation of the spring member is absorbed between the push-up member and the second slide member and does not affect the slide member. For this reason, it can avoid that the operation | movement of a spring member affects the advance / retreat operation | movement of a keytop.

  A key pressing mechanism comprising: a rotary shaft member provided along the key top; and a pressing piece that protrudes from the outer peripheral surface of the rotary shaft member toward the key top and can press the key top downward. The key pressing mechanism may be configured such that the rotary shaft member rotates in conjunction with the movement of the slide member, and the key top is pressed down by the pressing piece. Then, the key top can be easily switched between the use position and the pressed position with a simple configuration.

  The link mechanism may include a second slide member that moves in conjunction with the movement of the slide member to rotate the rotating shaft member and press the key top with the pressing piece.

  The first movable member may be a back leg provided on the back surface of the main body casing, and the second movable member may be a front leg provided on the surface of the main body casing. Then, for example, when the portable information device is a convertible PC, the back side leg is used as the protruding position in the use form of the notebook PC, and the front leg is used as the protruding position in the use form of the tablet PC. Can do.

  The first movable member is a key top of a keyboard device that is the operation means provided on the surface of the main body housing, and the second movable member is a function provided on a side surface or a back surface of the main body housing. It may be configured with a switch. Then, for example, when the portable information device is a convertible PC, the key top can be used as the use position in the use form of the notebook PC, and the function switch can be used as the protruding position in the use form of the tablet PC. .

  The hinge mechanism includes a first axis fixed to the main body casing so as not to rotate, a second axis fixed to the display casing so as not to rotate, the first axis, and the second axis. A hinge housing that rotatably supports the first shaft, and is rotatable integrally with the hinge housing relative to the first shaft on the outer peripheral surface of the first shaft. A cylindrical cam member provided with a surface is coaxially disposed in a rotatable state, and the slide member is coaxially disposed on an outer peripheral surface of the first shaft so as to be movable in an axial direction with respect to the first shaft. A cylindrical connecting portion that is provided so as to be movable in the axial direction with respect to the main body housing, and has a pressure receiving surface that is slidable in contact with the cam surface on an end surface of the cylindrical connecting portion, The slide member is moved forward by the cam surface of the cylindrical cam member that rotates on the outer peripheral surface of the first shaft. Receiving surface of the cylindrical connecting portion may be configured to move by being pressed. If it does so, the contact area between a cam surface and a pressure receiving surface can fully be ensured, and it will be prevented that both generate | occur | produce wear and a damage. In addition, even when the first shaft is configured to have an extremely small diameter, a sufficient contact area between the cam surface and the pressure receiving surface can be ensured, so that the device configuration can be reduced in size.

  According to the present invention, the first and second movable members can be moved back and forth at positions suitable for the usage pattern according to the rotation angle of the display housing, while ensuring the functionality and appearance quality of the product. It is possible to reduce the thickness.

At the left and right end portions of the rotary shaft member 50, drive end portions 50a protruding from the left and right side portions of the frame 24 are provided. Each drive end 50a is engaged with a slit 54a of a front / rear slider (second slide member) 54 provided on the left and right sides of the keyboard device 20 in a rotatable state. The front / rear slider 54 constitutes a link mechanism 56 described later, and is movable in the front / rear direction on the left and right of the keyboard device 20.

  As shown in FIG. 4, FIG. 5A and FIG. 5B, the rotary shaft member 50 is provided at the both ends of the linear base portion 50 b extending in the left-right direction along the rear side portion of the key top 22 and the base portion 50 b. Drive end 50a. The drive end 50a is formed by bending 90 degrees from the tip of the arm 50c obtained by bending the end of the base 50b by 90 degrees, and protrudes in the left-right direction so as to be parallel to the base 50b. As a result, both end portions of the rotary shaft member 50 have a crank shape.

  The base portion 50b is positioned and supported rotatably by a bearing portion 58 (see FIG. 4) provided on the base plate 30 or the frame 24 at an appropriate position in the left-right direction. Accordingly, when the left and right front / rear sliders 54 move in the front / rear direction, the driving end 50a moves in the front / rear direction together with the front / rear slider 54 while rotating in the slit 54a of the front / rear slider 54. As a result, the base portion 50b rotates around the axis while the arm portion 50c swings in a pendulum shape in the front-rear direction around the base portion 50b pivotally supported by the bearing portion 58 (see FIGS. 5A and 5B).

  The pressing piece 52 is bent from the mounting cylinder 60 that is externally fitted and fixed to the outer peripheral surface of the base portion 50b of the rotary shaft member 50, thereby projecting from the outer peripheral surface of the base portion 50b to the key top 22 side. The mounting cylinder 60 is fixed to the base 50b by caulking and spot welding. The pressing piece 52 is a plate piece protruding from the outer peripheral surface of the mounting cylinder 60. The pressing piece 52 is disposed in contact with the upper surface of the receiving piece 40 of each key top 22 and can press the receiving piece 40 downward.

  In the key pressing mechanism 26, when the left and right front / rear sliders 54 are moved rearward with the key top 22 in the use position shown in FIG. 5A, and the drive end 50a is moved rearward accordingly, the base 50b is pivoted. Rotate around. As a result, the pressing piece 52 protruding from the outer peripheral surface of the base portion 50b swings downward to push down the receiving piece 40 of the key top 22, and forcibly push down the key top 22. As a result, the key top 22 is held at the pressed position shown in FIG. 5B. In this depressed position, the upper surface 22a of the key top 22 is flush with or slightly lower than the upper surface of the frame 24, and the upper surface of the keyboard device 20 is configured to be a flat surface with no irregularities.

  On the other hand, when the left and right front / rear sliders 54 move forward in the opposite direction to the pressing operation while the key top 22 is in the pressing position shown in FIG. 5B, the base 50b also rotates in the opposite direction to that in the pressing operation. As a result, the pressing piece 52 swings upward and the pressing action on the receiving piece 40 is released. As a result, the key top 22 is moved up by the urging force of the rubber dome 41 and returned to the use position shown in FIG. 5A.

  The pressing operation of the key top 22 by the key pressing mechanism 26 is linked to the hinge mechanism 12 via the link mechanism 56 and corresponds to the rotational angle position of the display housing 14.

3. 3. Description of Leg 3.1 Description of Leg Configuration A specific configuration example of the leg 25 will be described.

  FIG. 7A is a side cross-sectional view schematically showing the state of the leg portion 25 at the 0 degree position and the 260 degree position. FIG. 7B is a side cross-sectional view schematically showing the state of the leg portion 25 from the 70 degree position to the 180 degree position. FIG. 7C is a side cross-sectional view schematically showing the state of the leg portion 25 from the 280 degree position to the 360 degree position.

  As shown in FIGS. 7A to 7C, the leg portion 25 is a leg member disposed in the opening 16 c of the surface 16 a of the main body housing 16. The leg portion 25 is a rubber leg made of, for example, a rubber material. The leg portion 25 may be formed of a resin material or the like. The leg portion 25 is integrally provided on the upper surface of the vertical slider 51 that is supported in the main body housing 16 so as to be movable up and down.

  The vertical slider 51 can move up and down under the guide action of a guide pin 53 attached to the inner surface of the surface 16 a of the main body housing 16. A coil spring 55 is externally attached to the guide pin 53. The coil spring 55 constantly urges the upper and lower sliders 51 in the direction (downward) in which the leg portion 25 is buried in the opening 16c. The vertical slider 51 has an inclined surface 51 a at one end portion of the lower surface thereof. The inclined surface 51a is a surface that is gradually inclined downward from the front side toward the rear side. The inclined surface 51a is disposed so as to face the push-up piece 54b of the front / rear slider 54 (see also FIG. 6).

3.2 Description of Lifting Structure of Leg Part An example of the structure of the protruding and protruding structure of the leg part 25 from the surface 16a of the main body housing 16 will be described.

  When the display housing 14 is between the 0-degree position and the 260-degree position, the vertical slider 51 that supports the leg portion 25 is in a position that does not contact the push-up piece 54 b of the front-rear slider 54. In other words, the front / rear slider 54 is in a position where the push-up piece 54b does not press the inclined surface 51a of the upper / lower slider 51. For this reason, the leg part 25 exists in the buried position buried from the surface 16a of the main body housing 16 by the urging force of the coil spring 55 (see FIGS. 7A and 7B).

  On the other hand, when the display housing 14 is rotated from the 260-degree position in the opening direction, the up-and-down slider 51 that supports the leg portion 25 has the push-up piece 54 b on the inclined surface 51 a by the rearward movement of the front-rear slider 54. Make sliding contact. As a result, the vertical slider 51 moves up against the urging force of the coil spring 55. At the 280-degree position, the upper and lower sliders 51 completely ride on the push-up piece 54b, and the leg portion 25 is the protruding position that protrudes upward from the surface 16a of the main body housing 16 (see FIG. 7C).

  The pressing operation of the leg portion 25 is linked to the hinge mechanism 12 via the link mechanism 56 and corresponds to the rotation angle position of the display housing 14.

4). Explanation of interlocking structure of display casing and key top and leg portion Hinge mechanism 12 and link for interlocking the pivoting operation of display casing 14 with the operation of key pressing mechanism 26 and the lifting operation of leg 25 A configuration example of the mechanism 56 will be described.

4.1 Description of Configuration of Hinge Mechanism A configuration example of the hinge mechanism 12 will be described.

  FIG. 8 is a plan view schematically showing a configuration example of the hinge mechanism 12. FIG. 8 representatively shows the configuration of the left hinge mechanism 12L. Hereinafter, the hinge mechanism 12L on the left side will be described as a representative. The right hinge mechanism 12R is identical in structure to the left hinge mechanism 12L except for a left-right symmetric structure, and thus detailed description thereof is omitted.

  As shown in FIG. 8, the hinge mechanism 12 includes a first shaft 62 extending in the left-right direction, a second shaft 63 installed in parallel with the first shaft 62, and the first shaft 62 and the second shaft 63. And a box-like hinge housing 64 for pivotally supporting the housing (see also FIGS. 2 and 3).

  The first shaft 62 rotates integrally with the main body casing 16 by fixing the mounting plate 62 a fixed to one end to the main body casing 16. The second shaft 63 rotates integrally with the display housing 14 by fixing an attachment plate 63 a fixed to one end to the display housing 14. The other ends of the first shaft 62 and the second shaft 63 are supported in a rotatable state inside the hinge housing 64. In the case of the present disclosure, the first shaft 62 and the second shaft 63 are configured to rotate synchronously via a gear train 65.

  In the first shaft 62, a cylindrical cam member 66 is coaxially disposed on the outer peripheral surface of the portion that is the outside of the hinge housing 64. The cylindrical cam member 66 is extrapolated on the outer peripheral surface of the first shaft 62 so as to be rotatable with respect to the first shaft 62. The cylindrical cam member 66 is provided integrally with a support plate 68 fixed to one side of the hinge housing 64. The support plate 68 is a plate-like member provided integrally with the hinge housing 64 and having a shaft hole through which the first shaft 62 and the second shaft 63 are rotatably inserted. When the first shaft 62 and the hinge housing 64 rotate relative to each other, the cylindrical cam member 66 rotates together with the hinge housing 64 relative to the first shaft 62. A cam surface 70 whose axial direction position changes along the circumferential direction is provided on the end surface on the one end side (right side in FIG. 8) of the cylindrical cam member 66.

  In the first shaft 62, a cylindrical connecting portion 74 of a left and right slider (sliding member) 72 is coaxially disposed on an outer peripheral surface of a portion adjacent to the cylindrical cam member 66. The left / right slider 72 is pressed by the cylindrical cam member 66 rotating on the outer peripheral surface of the first shaft 62 and moves in the left / right direction. The left / right slider 72 is supported so as to be movable in the left / right direction inside the main body housing 16. The left and right slider 72 is always urged by a coil spring 77 in a direction in which the cylindrical connecting portion 74 approaches the cylindrical cam member 66. The left / right slider 72 moves the front / rear slider in the front / rear direction by moving in the left / right direction, details of which will be described later.

  The cylindrical connecting portion 74 is disposed in the vicinity of a portion that is one end side (right side in FIG. 8) of the cylindrical cam member 66. The cylindrical connecting portion 74 is extrapolated on the outer peripheral surface of the first shaft 62 so as not to rotate and move in the axial direction with respect to the first shaft 62. The cylindrical connecting portion 74 is provided with a pressure receiving surface 75 on an end surface facing the cam surface 70 of the cylindrical cam member 66. The pressure receiving surface 75 is a surface whose axial position changes along the circumferential direction, and is capable of sliding contact with the cam surface 70 that rotates on the outer circumferential surface of the first shaft 62. The cam surface 70 and the pressure receiving surface 75 need to be in sliding contact smoothly while rotating coaxially. Therefore, in the present disclosure, the cam surface 70 and the pressure receiving surface 75 are configured to have a twisted shape inclined in the rotational direction in sliding contact with each other (for example, the first operating surface 70a and the first pressure receiving surface 75a in FIG. reference).

4.2 Description of Operation of Hinge Mechanism The operation of the hinge mechanism 12 will be described.

  9A to 9E are development views schematically showing the cylindrical cam member 66 and the cylindrical connecting portion 74 of the left and right slider 72 developed in the circumferential direction. FIG. 9A, FIG. 9B, FIG. 9C, FIG. 9D, and FIG. 9E show the positional relationships at 0 degree position, 70 degree position, 180 degree position, 260 degree position, and 280 degree position, respectively. FIG. 10 is a diagram showing the relationship between the rotation angle of the display housing 14 and the amount of movement of the left / right slider 72 and the front / rear slider 54.

  As shown in FIGS. 9A to 9E, the cam surface 70 of the cylindrical cam member 66 is formed so as to draw a mountain-shaped convex portion that spirally displaces in the axial direction (left-right direction) along the circumferential direction. It has the 1st operation surface 70a and the 2nd operation surface 70b, and the idling surface 70c formed along the circumferential direction. The first operating surface 70a is an inclined surface from the left side to the right side in FIG. 9A. The second operating surface 70b is an inclined surface from the right side to the left side in FIG. 9A. The idling surface 70c is a surface along the circumferential direction with no deviation in the left-right direction.

  On the cam surface 70, a pressure receiving surface 75 of the cylindrical connecting portion 74 is disposed so as to be slidable. The pressure receiving surface 75 includes a first pressure receiving surface 75a, a first idling surface 75b, and a second pressure receiving surface 75c that are formed so as to draw a trapezoidal recess that spirally displaces in the axial direction (left-right direction) along the circumferential direction. And a second idling surface 75d formed along the circumferential direction. The first pressure receiving surface 75a is an inclined surface from the left side to the right side in FIG. 9A. The second pressure receiving surface 75c is an inclined surface from the right side to the left side in FIG. 9A. The first idling surface 75b and the second idling surface 75d are surfaces along the circumferential direction with no deviation in the left-right direction.

  In the pressure receiving surface 75, the movement amount in the axial direction (left-right direction) of the second pressure receiving surface 75c is set larger than the movement amount in the axial direction of the first pressure receiving surface 75a. That is, the first pressure-receiving surface 75a is formed between the 0-degree position and the 70-degree position, and this axial movement amount (horizontal distance) is the second pressure-receiving surface from the 180-degree position to the 260-degree position. It is equal to the movement amount of 75c, and the second pressure receiving surface 75c has a structure in which a movement amount from the 260-degree position to the 280-degree position is further added.

  In the cam surface 70 and the pressure receiving surface 75, the first operating surface 70a is in sliding contact with the first pressure receiving surface 75a from the 0 degree position to the 70 degree position (refer to FIGS. 9A and 9B), and the position from the 70 degree position to the 180 degree position. In the meantime, the top portion 70d between the first working surface 70a and the second working surface 70b is in sliding contact with the first idling surface 75b (see FIGS. 9B and 9C). Further, in the cam surface 70 and the pressure receiving surface 75, the second operating surface 70b is slidably contacted with the second pressure receiving surface 75c between the 180 degree position and the 280 degree position (see FIGS. 9C to 9E), and 360 degrees from the 280 degree position. Until the position, the top portion 70d is in sliding contact with the second idling surface 75d (see FIG. 9E).

  First, a case where the display housing 14 is opened from the main body housing 16 via the hinge mechanism 12 will be described. 9A to 9E, solid arrows indicating the operations of the cylindrical cam member 66 and the left and right sliders 72 indicate operations when the display housing 14 is opened from the 0 degree position to the 360 degree position. (The same applies to FIGS. 12 to 13).

  In this case, the cylindrical cam member 66 that rotates integrally with the rotating hinge housing 64 rotates relative to the first shaft 62 and the pressure receiving surface 75 of the left and right slider 72 that cannot rotate with the first shaft 62. As a result, from the 0 degree position to the 70 degree position, as shown in FIGS. 9A and 9B, the first operating surface 70 a of the cam surface 70 of the cylindrical cam member 66 that moves upward is the first pressure receiving surface 75 a of the pressure receiving surface 75. Touch. For this reason, the left and right slider 72 moves to the left by the biasing force of the coil spring 77. The amount of movement of the left and right slider 72 at this time is set to 2 mm, for example, and the amount of movement of the front and rear slider 54 based on the movement of the left and right slider 72 is set to 8 mm, for example (see FIG. 10).

  From the 70 degree position to the 180 degree position, the left and right position of the left and right slider 72 does not change as shown in FIGS. 9B and 9C.

  9C to 9E, the second operation surface 70b of the cam surface 70 of the cylindrical cam member 66 that moves upward contacts the second pressure receiving surface 75c of the pressure receiving surface 75 from the 180 degree position to the 280 degree position. The left and right sliders 72 are moved to the right against the biasing force of the coil spring 77. At this time, the movement amount of the left and right sliders 72 is set to 2.5 mm, for example, and the movement amount of the front and rear sliders 54 based on the movement of the left and right sliders 72 is set to 10 mm, for example (see FIG. 10). As shown in FIG. 10, the position of the left and right sliders 72 (front and rear sliders 54) at the 0 degree position coincides with the position at the 260 degree positions, and the left and right sliders 72 (front and rear sliders 54) at the 280 degree position. Is arranged at a further advanced position.

  From the 280 degree position to the 360 degree position, as shown in FIG. 9E, the left and right position of the left and right slider 72 does not change.

  Next, a case where the display casing 14 is closed from the main casing 16 via the hinge mechanism 12 will be described. 9A to 9E, the broken-line arrow symbols indicating the operations of the cylindrical cam member 66 and the left and right slider 72 indicate the operation when the display housing 14 is closed from the 360 degree position to the 0 degree position. (The same applies to FIGS. 12 to 13).

  In this case, the cylindrical cam member 66 that rotates integrally with the hinge casing 64 that rotates in the direction opposite to that during the opening operation is provided on the pressure receiving surface 75 of the first shaft 62 and the left and right slider 72 that cannot rotate. Rotates relative to it. As a result, from the 360 degree position to the 280 degree position, the left and right positions of the left and right sliders 72 do not change as shown in FIG. 9E.

  From the 280 degree position to the 180 degree position, as shown in FIGS. 9E to 9C, the second operating surface 70 b of the cam surface 70 of the cylindrical cam member 66 that moves downward contacts the second pressure receiving surface 75 c of the pressure receiving surface 75. . For this reason, the left and right slider 72 moves to the left by the biasing force of the coil spring 77. At this time, the movement amount of the left and right sliders 72 is set to 2.5 mm, for example, and the movement amount of the front and rear sliders 54 based on the movement of the left and right sliders 72 is set to 10 mm, for example (see FIG. 10).

  From the 180-degree position to the 70-degree position, the left-right position of the left-right slider 72 does not change as shown in FIGS. 9C and 9B.

  From the 70 degree position to the 0 degree position, as shown in FIGS. 9B and 9A, the first operating surface 70 a of the cam surface 70 of the cylindrical cam member 66 that moves downward contacts the first pressure receiving surface 75 a of the pressure receiving surface 75. The left and right sliders 72 are moved to the right against the biasing force of the coil spring 77. The amount of movement of the left and right slider 72 at this time is set to 2 mm, for example, and the amount of movement of the front and rear slider 54 based on the movement of the left and right slider 72 is set to 8 mm, for example (see FIG. 10).

4.3 Description of Link Mechanism Configuration A configuration example of a link mechanism 56 that interlocks the rotation operation of the display housing 14 by the hinge mechanism 12 with the pressing operation of the key top 22 by the key pressing mechanism 26 and the lifting operation of the leg 25. Will be explained.

  11A, 12A, and 13A are perspective views of the hinge mechanism 12 (12L) and the link mechanism 56 at the 0 degree position, the 70 degree position, and the 280 degree position, respectively, as viewed from above. 11B, 12B, and 13B are perspective views of the hinge mechanism 12 (12L) and the link mechanism 56 at the 0-degree position, the 70-degree position, and the 280-degree position as viewed from below.

  The link mechanism 56 operates inside the main housing 16. As shown in FIG. 11B, the link mechanism 56 includes a left / right slider 72, a first link 78, a second link 80, and a front / rear slider 54. In the present embodiment, the link mechanism 56 operates on the surface of the attachment plate 62 a that fixes the first shaft 62 and the main body housing 16.

  The left / right slider 72 has the cylindrical connecting portion 74 described above. The left / right slider 72 is a plate-like member that moves in the left / right direction, which is the axial direction of the first shaft 62, on the mounting plate 62 a by the pressing force of the cylindrical cam member 66 and the biasing force of the coil spring 77. When the display casing 14 is rotated and the cylindrical cam member 66 rotates together with the hinge casing 64, the pressure receiving surface 75 of the cylindrical connecting portion 74 is in sliding contact with the cam surface 70 of the cylindrical cam member 66. Move left and right.

  The first link 78 is a thin plate-like plate-like member. One end of the first link 78 is rotatably connected to the left and right slider 72 using a connecting shaft 82. The other end of the first link 78 is rotatably connected to the second link 80 using a connecting shaft 84.

  The second link 80 is an L-shaped plate member. The second link 80 is rotatably connected to the first link 78 by using the connecting shaft 84 at the end portion of the L-shaped short side. The second link 80 is rotatably connected to the rear end portion of the front / rear slider 54 using a connecting shaft 86 at the end portion of the L-shaped long side. A portion that becomes an L-shaped corner portion of the second link 80 is rotatably supported using a rotation shaft 88 with respect to the main body housing 16 (the mounting plate 62a in the present disclosure).

  The front / rear slider 54 is a long rectangular plate-like member provided so as to be movable in the front / rear direction with respect to the main body housing 16 by a guide structure (not shown). The rear end of the front / rear slider 54 is rotatably connected to the second link 80 using a connecting shaft 86.

  In the link mechanism 56, when the display housing 14 is rotated with respect to the main body housing 16, the cylindrical cam member 66 rotates and the left and right sliders 72 move in the left and right directions, the first link 78 passes through the connecting shaft 82. And dragged by the left and right slider 72. As a result, the first link 78 rotates about the connecting shaft 84 as a rotation center. When the first link 78 rotates about the connecting shaft 84, the second link 80 is dragged by the first link 78 via the connecting shaft 84 this time. As a result, the second link 80 rotates about the rotation shaft 88 as a rotation center. As a result, the connecting shaft 86 that moves in the front-rear direction serves as an action point, and the front-rear slider 54 moves in the front-rear direction (see FIGS. 11B and 12B).

4.4 Explanation of Display Case Rotation Operation and Key Top and Leg Interlocking Operation Relationship between display case 14 rotation operation interlocked by link mechanism 56 and key top 22 and leg 25 elevation operation explain.

  First, when the display housing 14 is at the 0 degree position, as shown in FIGS. 9A, 11A, and 11B, the left and right sliders 72 are spaced apart from the tubular cam member 66 to some extent (in FIG. 11B, they are shifted to the right side). Position). For this reason, the second link 80 is at a position rotated counterclockwise to some extent in FIG. 11B, and the front / rear slider 54 is at a position moved rearward to some extent.

  In this state, as shown in FIG. 5B, the drive end 50 a of the rotary shaft member 50 is in a position moved to the rear side by the front and rear slider 54, and the key top 22 is pressed down by the receiving piece 40 being pushed down by the pressing piece 52. Held in position. Therefore, the upper surface 22a of the key top 22 is flush with or slightly lower than the upper surface of the frame 24, and the upper surface of the keyboard device 20 is configured to be flat. For this reason, the display housing 14 closed with respect to the main body housing 16 does not interfere with the key top 22, and the plate thickness of the portable information device 10 is made as thin as possible.

  Further, as shown in FIG. 7A, the push-up piece 54 b of the front-rear slider 54 is at a position facing the inclined surface 51 a of the upper-lower slider 51. Therefore, the leg portion 25 is held at the buried position where it is buried from the surface 16 a of the main body housing 16 by the urging force of the coil spring 55. For this reason, the display housing 14 closed with respect to the main body housing 16 does not interfere with the leg portion 25, and the plate thickness of the portable information device 10 is made as thin as possible.

  Next, when the display casing 14 is rotated in the opening direction from the 0 degree position, the hinge casing 64 of the hinge mechanism 12 is also rotated, and the cylindrical cam member 66 is rotated on the outer peripheral surface of the first shaft 62. . Between the 0 degree position and the 70 degree position (first angle position), the first operating surface 70a of the cam surface 70 is in sliding contact with the first pressure receiving surface 75a of the pressure receiving surface 75 as shown in FIG. 9B. As a result, the left and right slider 72 moves in the direction approaching the cylindrical cam member 66 (left side in FIG. 11B) by the biasing force of the coil spring 77. As a result, the second link 80 rotates clockwise in FIG. 11B, and the front / rear slider 54 moves to the front side.

  When the front / rear slider 54 moves forward, the drive end 50a of the rotary shaft member 50 also moves forward, so the rotary shaft member 50 rotates in the direction in which the pressing piece 52 moves upward (see FIG. 5A). As a result, the pressing action of the receiving piece 40 by the pressing piece 52 is released, so that the key top 22 also moves upward together with the pressing piece 52 by the urging force of the rubber dome 41. At this time, since the push-up piece 54b of the front / rear slider 54 moves in a direction away from the upper / lower slider 51 (see FIG. 7B), the leg portion 25 is held at the buried position.

  At the 70 degree position, as shown in FIGS. 12A and 12B, the left and right sliders 72 are located closest to the cylindrical cam member 66 (positions closest to the left side in FIG. 12B). For this reason, the second link 80 is the most clockwise position in FIG. 12B, and the front / rear slider 54 is the most moved position.

  In this state, as shown in FIG. 5A, the drive end 50a of the rotary shaft member 50 is in the position moved most forward by the front / rear slider 54, and is in the use position where the key top 22 is moved up most. At this time, the highest height position of the receiving piece 40 is defined by the pressing piece 52 moved to the uppermost position. As described above, in the portable information device 10, the key top 22 is in the use position protruding upward from the upper surface of the frame 24 when the display housing 14 is opened to the 70 ° position, so that the keyboard device 20 can be used. It becomes. At this time, the leg portion 25 is held at the buried position (see FIG. 7B).

  Between the 70-degree position and the 180-degree position (second angular position), as shown in FIGS. 9C and 12B, the first working surface 70a of the cylindrical cam member 66 and the top portion 70d of the second working surface 70b are moved to the left and right sliders 72. The first pressure swing surface 75b of the pressure receiving surface 75 is located. For this reason, even if the hinge housing 64 rotates and the cylindrical cam member 66 rotates, the left and right slider 72 does not move in the left and right direction. Therefore, since the position of the front / rear slider 54 does not change, as shown in FIG. 5A, the key top 22 is maintained at the use position, and the leg portion 25 is maintained at the buried position. That is, in the portable information device 10, the keyboard device 20 is maintained in a usable state between the positions of 70 to 180 degrees assumed to be used as a notebook PC. At this time, since the leg portion 25 is in the buried position, the leg portion 25 does not protrude on the surface 16a and the appearance quality is not impaired.

  Between the 180 degree position and the 260 degree position, the second working surface 70b of the cam surface 70 of the cylindrical cam member 66 is in sliding contact with the second pressure receiving surface 75c of the pressure receiving surface 75 of the left and right slider 72 as shown in FIG. 9D. Press this. As a result, the left and right sliders 72 are pushed out in the direction away from the cylindrical cam member 66 (right side in FIG. 12B). For this reason, the second link 80 rotates counterclockwise in the drawing, and the front / rear slider 54 moves rearward. When the front / rear slider 54 moves to the rear side, the drive end 50a of the rotary shaft member 50 also moves to the rear side, so that the rotary shaft member 50 rotates in the direction in which the pressing piece 52 moves downward (see FIG. 5B). As a result, the receiving piece 40 is pressed by the pressing piece 52, and the key top 22 moves downward together with the pressing piece 52 against the urging force of the rubber dome 41.

  At the 260-degree position (predetermined angle position), as shown in FIG. 9D, the left and right sliders 72 are arranged at the same position as the 0-degree position separated from the cylindrical cam member 66 to some extent. For this reason, the front / rear slider 54 is also moved to the rear side in the same manner as the 0 degree position (see FIG. 10).

  In this state, as shown in FIG. 5B, the key top 22 is held in the pressed position where the receiving piece 40 is pressed down by the pressing piece 52, as in the case of the 0 degree position. At the 260-degree position, as shown in FIG. 7A, the upper and lower sliders 51 do not receive the pushing force from the front and rear sliders 54, so the legs 25 are maintained in the buried position.

  Between the 260-degree position and the 280-degree position (third angle position), as shown in FIGS. 9D to 9E, the second operating surface 70b of the cam surface 70 of the cylindrical cam member 66 is in contact with the pressure receiving surface 75 of the left and right slider 72. This is further pressed while slidably contacting the second pressure receiving surface 75c. As a result, the left and right sliders 72 are pushed out and moved in the direction farthest from the cylindrical cam member 66 (the rightmost side in FIG. 13B). For this reason, the second link 80 rotates most counterclockwise in FIG. 13B, and the front / rear slider 54 moves most rearward. That is, at the 280 degree position, the left and right sliders 72 and the front and rear sliders 54 are arranged at positions moved further ahead of the 0 degree position and the 260 degree position (see FIG. 10).

  In this state, as shown in FIG. 7C, the upper and lower sliders 51 are raised by the push-up force from the front and rear sliders 54, and the leg portions 25 are in the protruding positions protruding upward from the surface 16 a of the main body housing 16. The front / rear slider 54 moves further to the rear side from the 280 degree position to the 360 degree position. However, since the upper and lower sliders 51 are kept on the push-up piece 54b, the protruding position of the leg 25 is Maintained.

  On the other hand, between the 260-degree position and the 360-degree position, as shown in FIG. 14C, the driving end 50a of the rotary shaft member 50 jumps out of the slit 54a of the front-rear slider 54 and rides on the upper surface of the front-rear slider 54 (FIG. 14C). (Refer to the frontmost rotary shaft member 50). For this reason, the rotational position of the rotating shaft member 50 does not change between the 260-degree position and the 360-degree position, and no further load in the pressing direction is applied to the key top 22 at the pressing position. In other words, in the portable information device 10, the surface 16a provided with the keyboard device 20 is configured to be a flat surface at the 360-degree position assumed to be used as a tablet-type PC, with the key top 22 being the pressed position. The leg part 25 protrudes from. As a result, when the portable information device 10 at 360 degrees is placed on a desk or the like, the leg portion 25 is landed and stabilized on the desk or the like, and the keyboard device 20 is prevented from being damaged or damaged. Yes (see FIG. 3).

  14A shows the positional relationship between the drive end 50a of the rotary shaft member 50 and the slit 54a at the 70-degree position where the front / rear slider 54 has moved to the foremost side, and FIG. 14B shows the front / rear direction from the state shown in FIG. 14A. 14C shows a state in which the slider 54 has moved rearward, and FIG. 14C shows a state in which the front / rear slider 54 has moved rearward from the state shown in FIG. 14B. Here, in FIGS. 14A to 14C, the groove widths W1 to W4 of the slits 54a of the front and rear sliders 54 are different from each other, so that the rotation timings of the rotary shaft members 50 are made different, for example, from the front side to the rear side. An example of a configuration in which the key tops 22 in each row sequentially become the pressed position and the use position is shown. Of course, the groove widths W1 to W4 of the respective slits 54a may be the same, and the key tops 22 of the respective rows may be in the pressed position or the use position at the same timing.

  On the other hand, when the display housing 14 at the 360 degree position is rotated in the closing direction, an operation in the direction opposite to the rotation in the opening direction occurs. That is, as the display housing 14 is rotated from the 360 degree position to the 180 degree position through the 260 degree position, the left and right sliders 72 move in the direction approaching the cylindrical cam member 66, and the front and rear sliders 54 are moved. Move forward. As a result, the key top 22 returns to the use position where the key top 22 is moved up most, and the leg portion 25 becomes the buried position. The use position of the key top 22 is maintained from the 180 degree position to the 70 degree position. Then, as the display housing 14 is rotated from the 70 degree position to the 0 degree position, the first operating surface 70a of the cam surface 70 is now in sliding contact with the first pressure receiving surface 75a of the pressure receiving surface 75. , And the front / rear slider 54 moves to the rear side. As a result, the key top 22 is flush with or slightly lower than the upper surface of the frame 24, and the leg portion 25 is maintained in the buried position. For this reason, the display housing | casing 14 can be closed, without the display 18 and the keytop 22 interfering.

5. Explanation of effects

  As described above, in the portable information device 10 according to the present embodiment, the key top 22 serving as the first movable member that advances and retreats from the surface 16 a that is the outer surface of the main body housing 16 and the surface that is the outer surface of the main body housing 16. A leg 25 serving as a second movable member that advances and retreats from 16a, and a left and right slider 72 (and a front and rear slider 54) that move by an amount of movement according to the rotation angle of the main body housing 16 and the display housing 14 by the hinge mechanism 12. And a link mechanism 56 that moves the key top 22 and the leg portion 25 forward and backward in conjunction with the rotation of the main body housing 16 and the display housing 14.

  Therefore, in the portable information device 10, the left and right sliders 72 move within a movement range that is linked to the rotation operation of the display housing 14 by the hinge mechanism 12, so that the two movable members move forward and backward according to the movement amount. As a result, when the key top 22 and the leg 25 are used as two movable members as in the present embodiment, the key top 22 is used as the use position in the use form of the notebook PC at the 90-degree position to the 180-degree position, for example. On the other hand, at the 0 degree position and the 360 degree position, the key top 22 can be depressed. Further, for example, the leg 25 can be used as the buried position in the usage form of the notebook PC at the 90 degree position to the 180 degree position, while the leg part 25 can be used as the protruding position at the 360 degree position. It becomes. Accordingly, the two movable members can be moved back and forth to a position suitable for the usage pattern according to the rotation angle of the display housing 14, and the thickness can be reduced while ensuring the functionality and appearance quality of the product. Is possible.

  In the present embodiment, the key top 22 and the leg portion 25 are exemplified as the first movable member and the second movable member that are interlocked with the rotation operation of the display housing 14 via the link mechanism 56, but these first movable member and The second movable member may be another part.

  For example, the pointing stick 20a and the function button 17a may be moved forward and backward together with or in place of the key top 22.

  For example, as shown in FIGS. 15A and 15B, the second leg 92 may be used as the first movable member instead of the key top 22. The second leg portion 92 appears and disappears from the back surface 16b of the main housing 16 at the same timing as the key top 22 by a mechanism similar to the key pressing mechanism 26, for example. Thereby, both the leg part (front side leg part) 25 and the second leg part (back side leg part) 92 are buried in the 0-degree position, and the thickness of the portable information device 10 is made as thin as possible. . Further, from the 70 degree position to the 180 degree position, the leg part 25 is maintained at the buried position, while the second leg part 92 is in the protruding position and protrudes from the back surface 16b of the main body housing 16 (see FIG. 15A). As a result, the second leg 92 functions as a leg on the bottom surface of the portable information device 10 that is a notebook PC. On the other hand, from the 180 degree position to the 360 degree position, the second leg portion 92 becomes the buried position again, so that when the tablet PC is used, the second leg portion 92 is prevented from interfering with the display housing 14 ( (See FIG. 15B).

  For example, as shown in FIGS. 16A and 16B, a function switch 94 may be used as the second movable member instead of the leg portion 25. The function switch 94 is, for example, a volume switch or a power switch. The function switch 94 is configured to appear and disappear from the side surface of the main body housing 16 at the same timing as that of the leg portion 25 by a mechanism similar to that of the leg portion 25, for example. The function switch 94 may be configured to protrude from the back surface 16 b of the main body housing 16. As a result, at the 0 degree position, the key top 22 and the function switch 94 are both buried and the thickness and outer shape of the portable information device 10 are made as thin and small as possible, and the function switch 94 becomes an obstacle. It will never be. Further, from the 70 degree position to the 180 degree position, the key top 22 becomes the use position, while the function switch 94 is maintained at the buried position. That is, in the usage form of the notebook PC, since the same operation as that of the function switch 94 can be performed by each key of the keyboard device 20, the function switch 94 is hidden as a buried position. On the other hand, in the 360-degree position where the tablet PC is used, the keyboard device 20 becomes unusable, while the function switch 94 becomes a protruding position and can be used. Therefore, when a tablet PC is used, a predetermined input operation can be performed using the function switch 94.

  In the portable information device 10, the left / right slider 72 rotates the display housing 14 from the 0 ° position to a first angle position smaller than the 180 ° position (70 ° position in this embodiment) with respect to the main body housing 16. While moving in one direction (left side in FIG. 9) in conjunction with the moving operation, other than the direction opposite to the one direction in conjunction with the turning operation from the first angular position (70 degree position) to the 0 degree position. Move in the direction (right side in FIG. 9), and is larger than the second angular position (180 degree position) from the second angular position (180 degree position in the present embodiment) that is larger than the first angular position (70 degree position). While moving in the other direction (right side in FIG. 9) in conjunction with the turning operation toward the third angular position (280 ° position in the present embodiment), the second angular position is shifted from the third angular position (280 ° position). In conjunction with the turning motion toward (180 degree position) Direction (to the left in FIG. 9). Then, the left and right slider 72 is second than the amount of movement in the other direction (2 mm in the present embodiment) in the rotational movement of the display housing 14 from the first angular position (70 degree position) to the 0 degree position. The amount of movement in the other direction (2.5 mm in this embodiment) is large in the turning operation from the angular position (180 degree position) to the third angular position (280 degree position). Therefore, for example, the key top 22 which is the first movable member is moved back and forth within a range of a small movement amount (2 mm in the present embodiment), while the leg portion 25 which is the second movable member is moved between the two movement amounts (0 .5 mm) can be advanced and retracted only within the range.

  As a result, the key top 22 can be set to a pressed position pressed down from the surface 16a of the main body casing 16 at least at the 0 degree position and the 360 degree position, while at least the first angular position (70 degree position) to the second angular position ( It can be set to a use position protruding from the surface 16a of the main body casing 16 within a range of 180 degrees. In addition, the leg portion 25 can be set to a buried position that is retracted from the surface 16a of the main body housing 16 in a range of at least 0 degree position and a first angular position (70 degree position) to a second angular position (180 degree position), It can be a protruding position that has advanced from the surface 16a of the main body casing 16 within a range of at least the third angular position (280 degree position) to 360 degree position. As described above, the amount of movement of the left and right slider 72 is made different between the closing operation and the opening operation of the display housing 14, so that the advancing / retreating position according to the characteristics of the key top 22 and the leg portion 25, which are each movable member. Can be set to

  In the portable information device 10, the display casing 14 is rotated from the second angular position (180 degree position) to a predetermined angular position (260 degree position in the present embodiment) smaller than the third angular position (280 degree position). When the left and right slider 72 moves in the other direction by performing a moving operation, the key top 22 moves back to the buried position by the movement of the left and right slider 72, while the leg portion 25 is maintained at the buried position. On the other hand, when the left and right slider 72 moves in the other direction by rotating the display housing 14 from the predetermined angular position (260 degree position) toward the third angular position (280 degree position), By movement, the leg 25 advances to the protruding position, while the key top 22 is maintained in the buried position. Thereby, it can set reliably to the advancing / retreating position according to the characteristic of the key top 22 and the leg part 25 which are each movable member.

  In the portable information device 10, on the outer peripheral surface of the first shaft 62, it can rotate integrally with the hinge housing 64 with respect to the first shaft 62, and a cam surface 70 is provided on the end surface thereof. A cylindrical cam member 66 is coaxially arranged, and the left and right sliders 72 have a cylindrical connecting portion 74 that is coaxially arranged on the outer peripheral surface of the first shaft 62 so as to be movable in the axial direction with respect to the first shaft 62. The left and right sliders 72 are provided with a pressure receiving surface 75 that is slidable in contact with the cam surface 70 at the end surface of the cylindrical connecting portion 74 and is provided so as to be movable in the axial direction with respect to the main body housing 16. It moves when the pressure receiving surface 75 of the cylindrical connecting portion 74 is pressed by the cam surface 70 of the cylindrical cam member 66 rotating on the outer peripheral surface of 62. As described above, the portable information device 10 has the cylindrical cam member 66 and the cylindrical connecting portion 74 of the left and right slider 72 arranged coaxially on the outer peripheral surface of the first shaft 62, and the cam surface 70 provided on each end surface. The load is transmitted to the pressure receiving surface 75. For this reason, a sufficient contact area between the cam surface 70 and the pressure receiving surface 75 can be secured, and both are prevented from being worn or damaged. In addition, even when the first shaft 62 is configured to have a very small diameter, a sufficient contact area between the cam surface 70 and the pressure receiving surface 75 can be ensured, so that the apparatus configuration can be reduced in size.

6). Description of Fail-Safe Mechanism A fail-safe mechanism 96 that prevents the occurrence of problems during the raising / lowering operation of the leg portion 25 will be described.

  In the elevating structure of the leg portion 25 described above, the leg portion 25 is in the protruding position when the display housing 14 is rotated from the 260-degree position to the 280-degree position (see FIG. 7C). During this operation, a case is assumed in which the user rotates the display housing 14 in a state where the top of the leg 25 is pressed with a fingertip or the top of the leg 25 is pressed against a desk or the like. . In this case, as the display housing 14 rotates, the front / rear slider 54 moves rearward, and the push-up piece 54 b presses the inclined surface 51 a of the upper / lower slider 51. However, since the rise of the leg portion 25 is prevented, the vertical slider 51 cannot rise. As a result, the movement of the front / rear slider 54 is forcibly blocked, and each element such as the cylindrical cam member 66 and the cylindrical connecting portion 74 of the hinge mechanism 12 for moving the front / rear slider 54 or the left / right slider 72 of the link mechanism 56 An excessive load is applied to each element such as the first link 78, which causes damage or malfunction.

  7A, the push-up piece 54b of the front / rear slider 54 is set to a position where it does not press the inclined surface 51a of the upper / lower slider 51 that supports the leg 25, as described above, and the leg 25 is in the buried position. It is in. However, depending on the assembly accuracy during manufacturing of the front / rear slider 54 and the upper / lower slider 51 and the processing accuracy of the parts, the front / rear slider 54 presses the upper / lower slider 51 at the 0 degree position, that is, the position shifts to the left in FIG. 7A. There is a possibility of being placed at the position. In this case, the push-up piece 54b slightly pushes up the leg portion 25 at the 0 degree position. That is, when the display housing 14 in the opened state is closed, the leg portion 25 unintentionally rises at the 0 degree position or an angle position slightly before that. As a result, the surface 14a of the display housing 14 may interfere with the leg portion 25 protruding from the opening 16c, and the display housing 14 may not be completely closed.

  FIG. 17 is a side sectional view schematically showing a configuration example including a fail safe mechanism 96 interposed between the leg portion 25 and the link mechanism 56. FIG. 17 shows the state of the leg 25 at the 0 degree position and the 260 degree position.

  As shown in FIG. 17, the fail-safe mechanism 96 includes a spring member 98 that connects the push-up piece (push-up member) 54 b and the front-rear slider 54. The spring member 98 is, for example, a compression coil spring. The spring member 98 is interposed between the push-up piece 54b and the front / rear slider 54, and supports the push-up piece 54b so that it can be displaced along the pressing direction (front / rear direction) against the upper / lower slider (support member) 51. That is, the push-up piece 54 b can be moved relative to the front-rear slider 54 in the front-rear direction via the spring member 98.

  FIG. 18A is a side cross-sectional view schematically showing a state in which the display housing 14 is opened from a position of 260 degrees with the finger F pressing the top of the leg 25. 18B is a side cross-sectional view schematically showing a state where the finger F is separated from the top of the leg portion 25 from the state shown in FIG. 18A.

  As shown in FIG. 18A, for example, when the display housing 14 is rotated from the 260-degree position in the opening direction with the finger F pressing the top of the leg 25, the fail-safe mechanism 96 is activated.

  That is, in this case, the front / rear slider 54 moves to the rear side from the 0 degree position shown in FIG. 17 as the display casing 14 rotates, but the ascent of the upper / lower slider 51 is restricted by the finger F. . For this reason, the push-up piece 54b is pressed against the inclined surface 51a, but the vertical slider 51 cannot be pushed up. As a result, the spring member 98 is compressed, and only the front / rear slider 54 moves rearward while the front / rear position of the push-up piece 54b is maintained. Thereby, the movement of the front / rear slider 54 is not restricted, and it is avoided that an excessive load is applied to the elements of the hinge mechanism 12 and the link mechanism 56 that move the slider 54. That is, even if the display housing 14 is opened to the 280 degree position or the 360 degree position while the leg 25 is pressed with the finger F, the hinge mechanism 12 and the link mechanism 56 are not damaged or malfunctioned.

  On the other hand, when the finger F is released from the leg portion 25 in the state shown in FIG. 18A in which the display housing 14 is opened at a position of 280 degrees or more, the push-up piece 54b is moved to the rear side by the biasing force of the spring member 98, and is inclined. Press 51a. As a result, as shown in FIG. 18B, the vertical slider 51 is pushed up by the push-up piece 54b, and the leg portion 25 becomes the protruding position. As described above, even when the display housing 14 is opened to the 280 degree position or the 360 degree position while the leg part 25 is pressed with the finger F, the leg part can be obtained by simply separating the finger F from the leg part 25. 25 moves to a desired protruding position. In this case, the front / rear slider 54 does not move, and the leg 25 is raised only by the urging force of the spring member 98. For this reason, the urging force of the spring member 98 needs to be set stronger than the urging force of the coil spring 55 that urges the vertical slider 51 downward.

  FIG. 19A is a side cross-sectional view schematically showing a state in which the front / rear slider 54 is assembled to the upper / lower slider 51 side during manufacturing. FIG. 19B is a side cross-sectional view schematically showing a state in which the display housing 14 is closed to the 0 degree position from the state shown in FIG. 19A. FIG. 19A shows a state immediately before the 0 degree position, for example, a state at the 1 to 2 degree position. FIG. 19B shows a state at the 0 degree position.

  As described above, depending on the assembling accuracy and the like at the time of manufacture, when the display housing 14 is at the 0 degree position, the front / rear slider 54 is displaced toward the upper / lower slider 51 (see the distance L in FIG. 19A). 54b may push the inclined surface 51a up. In this case, the leg 25 is slightly protruded from the surface 16 a of the main body housing 16 regardless of the 0 degree position, and interferes with the display housing 14. Accordingly, as shown in FIGS. 19A and 19B, the display housing 14 is closed toward the 0-degree position, and the leg 25 interferes with the display housing 14 at the 0-degree position or the angular position immediately before the 0-degree position. In such a case, the fail safe mechanism 96 acts.

  That is, in this case, the leg portion 25 is pressed downward by the surface 14 a of the display housing 14, and the push-up piece 54 b receives a pressing force by the inclined surface 51 a of the vertical slider 51. Therefore, only the push-up piece 54b moves to the front side while the front / rear position of the front / rear slider 54 is held (see the distance L in FIG. 19B), and the spring member 98 is compressed. As a result, the display housing 14 can be completely closed to the 0 degree position (see FIG. 19B). Therefore, the front / rear slider 54 does not move, and it is possible to avoid applying an excessive load to the elements of the hinge mechanism 12 and the link mechanism 56.

  The spring member 98 constituting such a fail safe mechanism 96 may be other than the structure provided directly between the push-up piece 54b and the front / rear slider 54, for example, provided between the front / rear slider 54 and the left / right slider 72. Also good. However, the portable information device 10 is provided with a coil spring 77 for moving the left / right slider 72. For this reason, it is structurally difficult to provide the spring member 98 between the front / rear slider 54 and the left / right slider 72. Further, the front / rear slider 54 has a function of pressing not only the leg portion 25 but also the key top 22. For this reason, if a spring member 98 is provided between the front / rear slider 54 and the left / right slider 72, the fail-safe action by the spring member 98 also affects the operation of pressing the key top 22. In other words, the fail safe mechanism 96 is provided with the spring member 98 between the push-up piece 54b and the front / rear slider 54 that is closest to the leg 25, so that the operation of the spring member 98 is performed by the front / rear slider 54. The operation of the key press mechanism 26 is avoided without affecting the operation. The fail safe mechanism 96 may be applied to the operation of the function switch 94. Further, the spring member 98 may be provided on the upper and lower slider 51 side, and for example, the inclined surface 51a may be elastically supported in the front-rear direction.

  It should be noted that the present invention is not limited to the above-described disclosure, and can be freely changed without departing from the gist of the present invention.

  The operation means provided on the surface 16a of the main body housing 16 may be other than the keyboard device 20, the pointing stick 20a, the touch pad 17, and the like. For example, a touch panel display may be provided and used as the operation means.

  In the above embodiment, the key top 22 is the pressed position between the 0 degree position and the 70 degree position and between the 180 degree position and the 360 degree position, and the key top 22 is the use position between the 70 degree position and the 180 degree position. The structure which becomes is illustrated. Furthermore, the leg part 25 becomes a buried position between the 0 degree position and the 260 degree position, and the configuration in which the leg part 25 becomes the protruding position between the 260 degree position and the 360 degree position is illustrated. Of course, the relationship between the height position of the key top 22 or the leg 25 and the rotation position of the display housing 14 may be changed. For example, the key top 22 does not start the ascending operation from the 0 degree position, but starts the ascending operation from the 30 degree position, and may be configured to be completely set to the use position at the 90 degree position instead of the 70 degree position. Good.

  In the above embodiment, the front and rear sliders 54 are moved by the left and right sliders 72, and the key tops 22 and the leg portions 25 are moved forward and backward by the front and rear sliders 54. However, for example, the key tops 22 and the leg portions 25 are moved by the left and right sliders 72. The left and right sliders 72 may be omitted, and the front and rear sliders 54 may be directly operated by the rotation of the hinge mechanism 12.
