Japanese Patent No. 6023228

In the configuration of Patent Document 1, the hinge shaft is arranged substantially in the center in the thickness direction of each housing. Therefore, since the hinge shaft does not protrude from the surface of the housing, the housing can be made thinner, and the housing can be changed to various usage modes by rotating the housing from the 0 degree position to the 360 degree position. it can. However, the adjacent end faces of each housing are formed in an arc shape in a side view in order to avoid interference during the rotation operation. As a result, the gap formed between the two displays becomes large, and when the two displays are used as one large screen, a wide divided portion is formed in the center of the displays.

The present invention has been made in consideration of the above-mentioned problems of the prior art, and it is possible to reduce the gap between the displays even if the housings having the displays are rotatably connected to each other. The purpose is to provide a portable information device that can be used.

The portable information device according to the first aspect of the present invention is a portable information device, which has a first housing having an upper surface and a lower surface and an upper surface and a lower surface, and is adjacent to the first housing. A second housing, a first display provided on the upper surface of the first housing, a second display provided on the upper surface of the second housing, and the first housing and the second housing. A hinge device for rotatably connecting one edge portions adjacent to each other is provided, and the hinge device arranges the upper surfaces of the first housing and the second housing side by side with each other. The flat plate form is rotatably connected to the first laminated form in which the upper surfaces thereof are overlapped with each other so as to face each other, and the first housing is fixed to the hinge device. A first base portion that supports the first display and is slidably supported relative to the first base portion along the alignment direction of the first housing and the second housing. The portable information device has a slide portion, and further operates in the first housing in conjunction with a rotation operation between the first housing and the second housing by the hinge device. The first link mechanism and the first housing and the second housing operate in response to the operation of the first link mechanism when the flat plate form is changed to the first laminated form. A first drive unit that slides the first slide unit in a direction that is relatively away from the second housing with respect to the first base unit is provided.

According to such a configuration, when the space between the first housing and the second housing is closed from the flat plate form to the first laminated form, at least one of the left and right displays slides in a direction in which they are separated from each other. .. Therefore, even if the displays are arranged close to each other with almost no gap between them, they can be prevented from interfering with each other during rotation. As a result, the portable information device can reduce the gap between the displays in the flat plate form as much as possible.

According to the above aspect of the present invention, it is possible to reduce the gap between the displays even if the housings each having the display are rotatably connected to each other.

Therefore, each element of the second hinge base 16B is designated by the same reference numeral as each element of the first hinge base 16A, and detailed description thereof will be omitted.

3. 3. Explanation of Rotational Actions and Actions and Effects Between Cases by Hinge Device Next, the rotation actions and actions and effects of the housings 12A and 12B by the hinge device 16 will be described with reference to FIGS. In the following, with reference to the 180-degree posture shown in FIG. 8A, the operation of rotating from the 180-degree posture to the 0-degree posture shown in FIG. 8D and the operation of rotating from the 180-degree posture to the 360-degree posture shown in FIG. 8F are described. It will be explained in order.

In the 180-degree posture shown in FIG. 8A, in the portable information device 10, the housings 12A and 12B are arranged side by side in a flat plate shape, and the displays 14A and 14B form a large screen of approximately one tablet-type PC.

The R-shaped portions 14Aa and 14Ba are close to each other with almost no gap between the displays 14A and 14B, and the gap between the displays is almost invisible. As a result, the user can use the two displays 14A and 14B as one screen substantially without discomfort.

Next, a case where the portable information device 10 changes from the 180-degree posture shown in FIG. 8A to the 0-degree posture shown in FIG. 8D will be described. In this case, the user grips the open edge side opposite to the one edge portion 12Aa, 12Ba side of each housing 12A, 12B, respectively, with the displays 14A, 14B inside, and valleys between the housings 12A, 12B. Fold it into a shape. Then, in the hinge device 16, the hinge bases 16A and 16B rotate together with the hinge shafts 25a and 25b about the axes of the hinge shafts 25a and 25b. At this time, since the hinge shafts 25a and 25b are inserted into the torque generating portions 26a and 26b, respectively, they rotate with a predetermined rotational torque with respect to the bridge portion 26. Further, the hinge bases 16A and 16B are fixed to the base portions 20A and 20B of the housings 12A and 12B, respectively. As a result, as shown in FIGS. 8B and 8C, the housings 12A and 12B rotate relatively in the direction in which they are gradually closed.

When the portable information device 10 is set to an angular posture between the housings 12A and 12B, for example, between the state shown in FIG. 8B and the state shown in FIG. 8C, for example, from a 90-degree posture to a 140-degree posture, the portable information device 10 is a notebook PC.

When the portable information device 10 is in the 0-degree posture shown in FIG. 8D, the display surfaces of the displays 14A and 14B face each other and the housings 12A and 12B are laminated, that is, the clam shell is closed. .. In this state, the displays 14A and 14B are housed inside the closed housings 12A and 12B. Therefore, the portable information device 10 can be carried and stored in a state where the displays 14A and 14B are protected while the housings 12A and 12B are miniaturized.

Next, a case where the portable information device 10 changes from the 180-degree posture shown in FIG. 8A to the 360-degree posture shown in FIG. 8F will be described. In this case, the user grips the open edges of the housings 12A and 12B, respectively, and folds the housings 12A and 12B in a mountain shape with the displays 14A and 14B on the outside. Then, as shown in FIG. 8E, the housings 12A and 12B rotate relatively in the direction in which they are gradually opened around the hinge shafts 25a and 25b.

When the portable information device 10 is in the 360-degree posture shown in FIG. 8F, the lower surfaces 12Ab and 12Bb face each other and the housings 12A and 12B are stacked. In this state, the user can use the portable information device 10 as a small-screen tablet PC (small-screen tablet mode) using one of the displays 14A and 14B.

By the way, as shown in FIGS. 8A to 8F, in the portable information device 10 of the present embodiment, the slide portions 21A and 21B supporting the displays 14A and 14B are accompanied by the rotation operation between the housings 12A and 12B. Slide. Further, as shown in FIGS. 4A to 4C, in the portable information device 10 of the present embodiment, the cover member 18 also slides with the rotation operation between the housings 12A and 12B. The sliding operation of the sliding portions 21A and 21B and the cover member 18 is interlocked with the rotating operation of the hinge device 16. Therefore, next, a configuration in which the slide portions 21A and 21B (displays 14A and 14B) are slid and a configuration in which the cover member 18 is slid will be described in order.

4. Explanation of the configuration for sliding the slide portion 4.1 Explanation of the support structure of the slide portion First, the support structures of the slide portions 21A and 21B will be described. FIG. 9 is a schematic cross-sectional view taken along the line IX-IX in FIG.

As shown in FIG. 9, the first slide portion 21A includes a pair of guide rails 36, 37 provided so as to straddle the first hinge base 16A in the Y direction. The guide rails 36 and 37 are block-shaped parts made of a self-lubricating resin material such as polyacetal (POM) or polytetrafluoroethylene (PTFE). The guide rails 36 and 37 are fixed to the upper plate 21Aa and the side plate 21Ab and extend in the X direction. The guide rails 36 and 37 slidably abut with the guide portions 31a and 32a of the first hinge base 16A, respectively. The guide rails 36, 37 may have a configuration extending in the longitudinal direction of the guide portions 31a, 32a, or may be a piece component that is brought into contact with a plurality of locations of the guide portions 31a, 32a at intervals.

The guide rails 36 and 37 are arranged so as to face each other with the first hinge base 16A sandwiched in the Y direction. The guide rails 36 and 37 have a pair of upper and lower sliding protrusions 36a and 37a on opposite surfaces. The sliding protrusions 36a and 37a slidably come into contact with the vertical surfaces of the guide portions 31a and 32b, respectively. Further, the lower surfaces of the guide rails 36 and 37 slidably contact the bottom surfaces of the guide portions 31a and 32b, respectively. Since it is necessary to engage the guide rails 36 and 37 from top to bottom on the side walls 31 and 32, the side walls 31 and 32 are formed in a substantially L-shaped cross section with an open upper portion (see FIGS. 7 and 9). Therefore, the upper openings of the guide portions 31a and 31b are closed by the lid plate 38 after the guide rails 36 and 37 engage with the guide portions 31a and 32b, respectively. As a result, the guide rails 36 and 37 are prevented from coming off from the guide portions 31a and 32a.

Therefore, the first slide portion 21A and the display 14A supported by the first slide portion 21A are slidably supported in the X direction with respect to the first hinge base 16A and the first base portion 20A. At this time, the first slide portion 21A has a pair of pressure receiving pieces 39, 39 in the Y direction at positions facing the side wall 30 of the first hinge base 16A (see FIG. 10). Each pressure receiving piece 39 enters into each accommodating portion 30a formed on the side wall 30 and is fixed to one end of the coil spring 34. The coil spring 34 constantly urges the first slide portion 21A with respect to the first hinge base 16A in the direction away from the hinge device 16 (on the right side in FIGS. 7 and 10A) via the pressure receiving piece 39. That is, the first slide portion 21A is constantly urged in the direction retracting from the hinge device 16 in the X direction with respect to the first hinge base 16A.

The second slide portion 21B has the same structure as the first slide portion 21A described above except that it has a symmetrical structure (see also reference numeral 21B shown in parentheses in FIG. 9 and the like). Therefore, each element constituting the support structure for the second hinge base 16B and the second base portion 20B of the second slide portion 21B and the second slide portion 21B has the same reference numerals as the respective elements of the first slide portion 21A. A detailed description will be omitted.

4.2 Explanation of the mechanism for operating the slide unit Next, the mechanism for operating the slide units 21A and 21B will be described. As shown in FIG. 7, the first hinge base 16A supports the first link mechanism 40A and the first drive unit 41A. 10A to 10C are bottom views schematically showing the operations of the first link mechanism 40A and the first drive unit 41A during the rotational operation of the hinge device 16. FIG. 10A shows a state in a 0 degree posture, FIG. 10B shows a state in a 180 degree posture, and FIG. 10C shows a state in a 360 degree posture.

As shown in FIGS. 7 and 10A, the first link mechanism 40A includes an input member 42 and a speed reducer 43.

The input member 42 is a plate having a substantially T-shape in a plan view. The input member 42 has a slide base 42a and a hinge engaging portion 42b. The slide base 42a is arranged inside the side wall 29 and is slidably supported in the Y direction on the inner surface of the base plate 28. The slide base 42a has a rack gear 44 extending in the Y direction formed on one end surface opposite to the hinge shaft 25a side.

The hinge engaging portion 42b projects from the other end surface of the slide base 42a and reaches the hinge shaft connecting body 24 through the opening 29b formed in the side wall 29. A pair of engaging pieces 45, 45 are projected from the tip of the hinge engaging portion 42b. Each engaging piece 45 is a thin pin-shaped portion. A pair of guide grooves 46, 46 are formed on the outer peripheral surface of the hinge shaft 25a. Each guide groove 46 is formed on the outer peripheral surface of the hinge shaft 25a, and is formed in a spiral shape by gradually being displaced in the axial direction (Y direction) along the circumferential direction of the outer peripheral surface. Each engaging piece 45 is slidably engaged with each guide groove 46. The guide groove 46 of the hinge shaft 25a has the same structure as the guide groove 46 of the hinge shaft 25b shown in FIG. 7. The shape of the guide groove 46 is substantially the same as that of the guide groove 112 shown in FIG. 29, which will be described later.

As shown in FIG. 10A, the speed reducer 43 is a gear mechanism in which a plurality of gears 48a to 48e are meshed with each other. FIG. 7 illustrates a speed reducer 43 having specifications different from those shown in FIG. 10A and the like, but the following description will be made with reference to the configuration example shown in FIG. 10A and the like. The gear 48a has the largest diameter and meshes with the rack gear 44. The gears 48b and 48c are gears having a diameter smaller than that of the gear 48a, and are arranged on both sides of the gear 48a in a state of being meshed with the gear 48a. The gears 48d and 48e are gears having a smaller diameter than the gears 48b and 48c, and mesh with the gears 48b and 48d, respectively. When the slide base 42a slides in the Y direction of the speed reducer 43, the gear 48a receives an input from the rack gear 44. The speed reducer 43 amplifies the input to the gear 48a, that is, the slide distance of the slide base 42a by the gears 48a to 48e, and outputs the gears 48d and 48e to operate the first drive unit 41A.

The first drive unit 41A is a mechanism for sliding the first slide unit 21A. As shown in FIGS. 7 and 10A, the first drive unit 41A has a drive member 50 and a slide guide hole 51.

The drive member 50 is a plate having a substantially T-shape in a plan view, and is considerably larger than the input member 42. The drive member 50 is slidably supported in the Y direction on the inner surface of the base plate 28. The drive member 50 has a rack gear 54 extending in the Y direction formed on one end surface on the speed reducer 43 side. The rack gear 54 meshes with the output gears 48d and 48e of the speed reducer 43.

The slide guide hole 51 is an elongated hole formed in a substantially V shape in a plan view. The slide guide hole 51 is based on the first point 51a at the apex of the V-shape protruding toward the hinge device 16, the second point 51b at one tip of the V-shape, and the second point 51b at the other tip of the V-shape. The three points 51c communicate with each other. In the slide guide hole 51 of the present embodiment, the X-direction distance from the first point 51a to the second point 51b is set to be slightly larger than the X-direction distance from the first point 51a to the third point 51c.

A drive pin 56 is slidably inserted into the slide guide hole 51. The drive pin 56 is fixed to the first slide portion 21A. Specifically, as shown in FIG. 9, the drive pin 56 projects downward from the upper plate 21Aa of the first slide portion 21A. Reference numeral 57 in FIG. 7 is a bracket plate interposed between the upper plate 21Aa and the drive pin 56. In FIG. 9, the bracket plate 57 is not shown. The bracket plate 57 may be omitted, and the drive pin 56 may be directly fixed to the upper plate 21Aa.

As shown in FIG. 6, a second link mechanism 40B and a second drive unit 41B are arranged on the second hinge base 16B side of the hinge device 16. The second link mechanism 40B and the second drive unit 41B have the same structure as the first link mechanism 40A and the first drive unit 41A described above, except that they have a symmetrical structure. That is, although detailed description and illustration are omitted, the second link mechanism 40B also includes an input member 42 and a speed reducer 43. The second drive unit 41B is also provided with a drive member 50 and a slide guide hole 51. The drive pin 56 of the second drive unit 41B is fixed to the second slide unit 21B.

4.3 Description of the mechanism for driving the cover member Next, the mechanism for driving the cover member 18 will be described. The drive member 50 of the first drive unit 41A further has a cover guide hole 52. The cover guide hole 52 constitutes the first cover drive unit 58A. The first cover drive unit 58A is a mechanism for sliding the first cover unit 18A. The first cover drive unit 58A is composed of a drive member 50 that is also used as the first drive unit 41A, and a cover guide hole 52.

The cover guide hole 52 is a substantially linear elongated hole whose central portion is slightly bent in a plan view. The cover guide hole 52 is based on the first point 52a at the bent portion in the central portion, the second point 52b at the tip on the hinge device 16 side, and the third point at the tip opposite to the hinge device 16 side. 52c and 52c communicate with each other. In the cover guide hole 52 of the present embodiment, the X-direction distance from the first point 52a to the third point 52c is set to be slightly larger than the X-direction distance from the first point 52a to the second point 52b.

A cover pin 60 is slidably inserted into the cover guide hole 52. The cover pin 60 is fixed to the first cover portion 18A slidably arranged on the lower surface side of the first hinge base 16A (see FIG. 9). The cover pin 60 is fixed to the first cover portion 18A through an elongated hole 61 in the X direction formed in the base portion 20A. Therefore, the cover pin 60 can be moved only in the X direction.

As shown in FIG. 6, a second cover drive unit 58B is arranged on the second hinge base 16B side of the hinge device 16. The second cover drive unit 58B has the same structure as the first cover drive unit 58A described above, except that the structure is symmetrical. That is, although detailed description and illustration are omitted, the second cover drive unit 58B also includes a cover guide hole 52 formed in the drive member 50. The cover pin 60 of the second cover drive unit 58B is fixed to the second cover unit 18B in a state of being movable in the X direction. The cover drive units 58A and 58B may be configured such that the drive units 41A and 41B and the drive member 50 are not shared, and the cover guide hole 52 is separately provided in a dedicated drive member.

4.4 Explanation of the operation and action / effect of the slide portion and the cover member Next, the slide operation and action / effect of the slide portions 21A and 21B and the cover member 18 when the housings 12A and 12B are rotated by the hinge device 16 are described. It will be described with reference to FIGS. 10A to 10C and FIGS. 4A to 4C. In the following, with reference to the 180-degree posture shown in FIGS. 4B and 10B, the operation of rotating from the 180-degree posture to the 0-degree posture shown in FIGS. 4A and 10A and the 360-degree posture shown in FIGS. 4C and 10C are shown below. The operation of rotating to the degree posture will be described in order.

When the portable information device 10 is in the 180-degree posture shown in FIG. 8A, the link mechanisms 40A and 40B, the drive units 41A and 41B, and the cover drive units 58A and 58B are in the state shown in FIG. 10B. In this state, both the input member 42 and the drive member 50 are located substantially in the center of the slide range in the Y direction. Each of the slide portions 21A and 21B is in a position where it slides most toward the hinge device 16 side (see FIGS. 8A and 10B). Therefore, the coil spring 34 is in the most compressed state.

Further, in this state, each of the slide portions 21A and 21B is attracted by the adsorbed body 63 to the magnet 62 installed on the upper surface of the hinge bases 16A and 16B. The magnets 62 are provided on the upper surfaces of the side walls 29 on both ends in the Y direction. The slide portions 21A and 21B have an adsorbed body 63 formed of an iron plate, a magnet, or the like on the lower surface of the upper plate 21Aa. As a result, in the large-screen tablet mode of the 180-degree posture, the portable information device 10 has the vicinity of the edges 12Aa and 12Ba of the displays 14A and 14B under the suction action of the magnet 62 and the adsorbed body 63. It is held stably without sticking. The magnet 62 and the adsorbed body 63 may be omitted.

Next, the operation when the portable information device 10 changes from the 180-degree posture shown in FIG. 8A to the 0-degree posture shown in FIG. 8D will be described. During this operation, as shown in FIG. 10A, in the link mechanisms 40A and 40B, the engaging piece 45 of the hinge engaging portion 42b slides on the guide groove 46 of the rotating hinge shafts 25a and 25b, and the input member 42 is shown in FIG. Slide to the right inside. Then, the slide of the input member 42 is input to the speed reducer 43 via the rack gear 44, amplified, and output to the drive units 41A and 41B. In the drive units 41A and 41B, the drive member 50 slides to the left in the drawing under the meshing action of the rack gear 54 and the gears 48d and 48e.

At this time, the drive pin 56 is fixed to the slide portions 21A and 21B and can move only in the X direction. Therefore, as shown in FIGS. 10B and 10A, the drive pin 56 moves in the slide guide hole 51 from the first point 51a to the second point 51b. Therefore, the slide portions 21A and 21B slide in the direction away from the hinge device 16, that is, in the direction away from each other in the X direction as the drive pin 56 moves in the X direction. As a result, the slide portions 21A and 21B and the displays 14A and 14B move in a direction in which they are separated from each other in conjunction with the rotation operation between the housings 12A and 12B in the closing direction (see FIGS. 8A to 8D). .. As a result, it is prevented that the R-shaped portions 14Aa and 14Ba of the displays 14A and 14B interfere with each other immediately after the start of rotation shown in FIGS. 8A to 8B, and a smooth rotation operation between the housings 12A and 12B is performed. It is possible. Immediately after the start of this rotation, the sliding portions 21A and 21B slide more smoothly due to the urging force of the coil spring 34. Therefore, the housings 12A and 12B rotate more smoothly.

On the other hand, the cover pin 60 is fixed to the cover portions 18A and 18B and can move only in the X direction. Therefore, as shown in FIGS. 10B and 10A, the cover pin 60 moves in the cover guide hole 52 from the first point 52a to the second point 52b. Therefore, the cover portions 18A and 18B both move to the connecting portion 18C side as the cover pin 60 moves in the X direction. That is, as shown in FIGS. 4B and 4A, in the first cover portion 18A, the open edge portion on the side opposite to the connecting portion 18C side moves in the direction of retreating from the open edge portion of the first housing 12A. Similarly, the open edge portion of the second cover portion 18B moves in a direction in which the open edge portion retracts from the open edge portion of the second housing 12B. That is, the cover member 18 is outside the rotation center of the hinge device 16 (the axes of the hinge shafts 25a and 25b) in the rotation direction. Therefore, the cover member 18 receives a tensile force in the vicinity of the connecting portion 18C due to the difference in peripheral length between the housings 12A and 12B during the closing operation. Therefore, since the cover portions 18A and 18B retract to the connecting portion 18C side during the closing operation, it is possible to prevent the cover member 18 and the support portions between the cover member 18 and the housings 12A and 12B from being excessively loaded. ..

Next, the operation when the portable information device 10 changes from the 180-degree posture shown in FIG. 8A to the 360-degree posture shown in FIG. 8F will be described. During this operation, in the link mechanisms 40A and 40B, as shown in FIG. 10C, the input member 42 slides to the left side in the drawing, and the drive member 50 slides to the right side in the drawing.

Therefore, as shown in FIGS. 10B and 10C, the drive pin 56 moves in the slide guide hole 51 from the first point 51a to the third point 51c. Therefore, the slide portions 21A and 21B slide in the direction away from the hinge device 16, that is, in the direction away from each other in the X direction as the drive pin 56 moves in the X direction. As a result, the slide portions 21A and 21B and the displays 14A and 14B move in a direction in which they are separated from each other in conjunction with the rotation operation between the housings 12A and 12B in the opening direction (FIGS. 8A, 8E and FIG. See 8F). As a result, as shown in FIGS. 4C and 8F, in the portable information device 10, the R-shaped portions 14Aa and 14Ba of the displays 14A and 14B are arranged inside the bridge portion 26 of the hinge device 16 in the 360-degree posture. Will be done. As a result, the R-shaped portions 14Aa and 14Ba are located at the outermost edge portion of the portable information device 10 in a 360-degree posture, and are prevented from being damaged when dropped or the like.

The slide portions 21A and 21B may not slide during the operation from the 180-degree posture to the 360-degree posture. In this case, the slide guide hole 51 may have a shape in which the position in the X direction does not change from the first point 51a to the third point 51c.

On the other hand, as shown in FIGS. 10B and 10C, the cover pin 60 moves in the cover guide hole 52 from the first point 52a to the third point 52c. Therefore, the cover portions 18A and 18B both move in the direction away from the connecting portion 18C as the cover pin 60 moves in the X direction. That is, as shown in FIGS. 4B and 4C, in the first cover portion 18A, the open edge portion on the side opposite to the connecting portion 18C side moves in the direction of advancing toward the open edge portion of the first housing 12A. .. Similarly, the open edge portion of the second cover portion 18B moves in a direction in which the open edge portion advances toward the open edge portion of the second housing 12B. That is, the cover member 18 is inside the hinge shafts 25a and 25b in the rotational direction during the opening operation between the housings 12A and 12B. Therefore, the cover member 18 receives a compressive force in the vicinity of the connecting portion 18C due to the difference in peripheral length at this time. Therefore, since the cover portions 18A and 18B advance to the opposite side to the connecting portion 18C side during the opening operation, it is possible to prevent the cover member 18 from being excessively bent or wrinkled when the posture is 360 degrees.

As described above, in the slide guide hole 51 of the present embodiment, the X-direction distance from the first point 51a to the second point 51b is larger than the X-direction distance from the first point 51a to the third point 51c. .. Therefore, the slide distances of the slide portions 21A and 21B are larger when changing from the 180-degree posture to the 0-degree posture than when changing from the 180-degree posture to the 360-degree posture. As a result, as shown in FIGS. 3 and 4C, when the hinge device 16 is exposed to the outside in a 360-degree posture, the amount of protrusion of the hinge device 16 from the edges 12Aa and 12Ba of the housings 12A and 12B is minimized. It can be suppressed, and deterioration of appearance quality can be suppressed.

Further, as described above, in the cover guide hole 52 of the present embodiment, the X-direction distance from the first point 52a to the third point 52c is larger than the X-direction distance from the first point 52a to the second point 52b. .. Therefore, the sliding distances of the cover portions 18A and 18B are larger when changing from the 180-degree posture to the 360-degree posture than when changing from the 180-degree posture to the 0-degree posture. As a result, as shown in FIGS. 1 and 4A, it is possible to suppress bending or crushing of the articulated portion 18C whose thickness is significantly smaller in the 360-degree posture than in the 0-degree posture. At this time, since the hinge device 16 retracts from the one edge portions 12Aa and 12Ba of the hinge device 16, even if the cover portions 18A and 18B advance to some extent, the open edge portion thereof is larger than the open edge portion of the housings 12A and 12B. It does not protrude first and deteriorate the appearance quality (see FIG. 4C).

The portable information device 10 has a slide structure of one of a slide structure of displays 14A and 14B by slide portions 21A and 21B and drive units 41A and 41B and a slide structure of covers 18A and 18B by cover drive portions 58A and 58B. It may be equipped with only.

As described above, the portable information device 10 is provided with the link mechanisms 40A and 40B and the drive units 41A and 41B, so that when the housings 12A and 12B are closed from the 180-degree posture to the 0-degree posture. The displays 14A and 14B slide in a direction away from each other. Therefore, even if the displays 14A and 14B are arranged close to each other with almost no gap between them, they can be prevented from interfering with each other during rotation. As a result, the portable information device 10 can reduce the gap between the displays 14A and 14B in the 180-degree posture. Further, the portable information device 10 includes the link mechanisms 40A and 40B and the cover drive units 58A and 58B, so that the cover member 18 can be slid to an optimum position according to the rotational posture of the housings 12A and 12B. Can be done. Therefore, it is possible to prevent wrinkles, bending, and the like from occurring in a part of the cover member 18 during the rotation operation between the housings 12A and 12B. Further, in the portable information device 10, the link mechanisms 40A and 40B and the drive units 41A and 41B are connected by a gear mechanism via the speed reducer 43, so that the slide unit receives the rotational operation of the hinge device 16. The 21A and 21B and the cover member 18 can be slid smoothly.

5. Description of the link mechanism and the drive unit according to the first modification 5.1 Explanation of the configuration of the link mechanism and the drive unit according to the first modification FIG. 11 shows the first link mechanism 70A and the first drive according to the first modification. It is a perspective view which looked at the part 71A from the lower surface side. FIG. 12 is a perspective view of the first link mechanism 70A and the first drive unit 71A shown in FIG. 11 as viewed from the lower surface side at different angles. FIG. 13 is a partially enlarged perspective view of the first link mechanism 70A and the first drive unit 71A shown in FIG. 11 as viewed from the upper surface side. FIG. 14 is an enlarged perspective view of a main part of the first link mechanism 70A and the first drive unit 71A shown in FIG. 13 as viewed from the lower surface side. In FIGS. 11 to 14, the first hinge base 16A, the first base portion 20A, the hinge device 16 and the like are not shown as appropriate. In each of the figures shown in FIGS. 11 and 11C, reference numerals that are the same as the reference numerals shown in FIGS. 1 to 10C show the same or similar configuration, and therefore, a detailed description will be given as to exhibit the same or similar functions and effects. Omit.

As shown in FIGS. 11 to 14, the first link mechanism 70A includes a pair of belt mechanism portions 72 and 73 and a belt drive shaft 76. That is, the first link mechanism 70A includes two sets of belt mechanism portions 72 and 73.

The belt drive shaft 76 is provided so as to divide a part of the hinge shaft 25a and connect the hinge shafts 76 to each other. As a result, the belt drive shaft 76 rotates coaxially with the hinge shaft 25a. That is, the belt drive shaft 76 forms a part of the hinge shaft 25a. FIG. 13 illustrates a state in which the belt drive shaft 76 of the second link mechanism 70B on the second housing 12B side is omitted. The belt drive shaft 76 may be omitted. In this case, the belts 72a and 72b may be directly wound around the hinge shaft 25a.

One belt mechanism portion 72 has a pair of belts 72a and 72b in the Y direction, connecting members 72c and 72d fixed to the belts 72a and 72b, respectively, and a rotary link 72e.

The belts 72a and 72b are flexible belt-shaped members made of a woven fabric such as resin or a sheet. The belts 72a and 72b are wound around the belt drive shaft 76 side by side with each other. A plurality of claws (not shown) arranged in the circumferential direction are formed on the outer peripheral surface of the belt drive shaft 76. The belts 72a and 72b are wound around the belt drive shaft 76 so as to be non-rotatable by being fitted with the claws. As shown in FIG. 13, one belt 72a is wound around the belt drive shaft 76 from above. The other belt 72b is wound around the belt drive shaft 76 from below.

The connecting members 72c and 72d are members made of metal or resin and having a block-shaped portion on the belt 72a and 72b sides and a plate-shaped portion on the opposite side. A portion of the belt 72a drawn from the belt drive shaft 76 is fixed to the connecting member 72c. A portion of the belt 72b drawn from the belt drive shaft 76 is fixed to the connecting member 72d. The connecting members 72c and 72d are supported on the inner surface of the base plate 28 in a state of being slidable in the winding direction and the drawing direction of the belts 72a and 72b with respect to the belt drive shaft 76, that is, in the X direction. In the case of the present embodiment, the connecting member 72d on the inner side of the connecting member 72c on the outer side in the Y direction is formed to be longer.

The rotating link 72e is a strip-shaped plate. The rotary link 72e is arranged on the lower surface side of the connecting members 72c and 72d, and connects the connecting members 72c and 72d so as to slide in opposite directions. The central portion of the rotary link 72e in the longitudinal direction is rotatably supported by the base plate 28 via the rotary shaft 78a. The rotary link 72e has a shaft pin 78b projecting from the first end and a shaft pin 78c projecting from the second end (see FIG. 13).

It has a link 73e.

The belts 73a and 73b are also wound around the belt drive shaft 76 so as not to rotate relative to each other. As shown in FIG. 13, one belt 73a is wound around the belt drive shaft 76 from above. The other belt 73b is wound around the belt drive shaft 76 from below. A portion of the connecting member 73c drawn from the belt drive shaft 76 of the belt 73a is fixed. A portion of the connecting member 73d drawn from the belt drive shaft 76 of the belt 73b is fixed. In the connecting members 73c and 73d, the connecting member 72c is made longer than the connecting member 72d.

As for the rotary link 73e, the central portion in the longitudinal direction is rotatably supported by the base plate 28 via the rotary shaft 78a, the shaft pin 78b is projected at the first end portion, and the shaft pin 78c protrudes at the second end portion. It is installed. The shaft pin 78b is slidably inserted into a long hole in the Y direction formed in the connecting member 73c. The shaft pin 78c is slidably inserted into a long hole in the Y direction formed in the connecting member 73d.

The first drive unit 71A includes a rotation lever member 80 and a drive pin 81 connected to one belt mechanism unit 72, and a rotation lever member 82, a drive pin 83 and a cover pin connected to the other belt mechanism unit 73. 85 and. The first drive unit 71A includes the same functions as the first cover drive unit 58A by having the cover pin 85.

The rotary lever member 80 is a strip-shaped plate. The first end of the rotary lever member 80 is arranged on the lower surface side of the connecting member 72d. In the rotary lever member 80, the shaft pin 80a is slidably inserted into the elongated hole in the Y direction formed at the first end portion. The shaft pin 80a is projected from the lower surface of the connecting member 72d. As a result, the first end portion of the rotary lever member 80 is rotatably connected to the connecting member 72d. The drive pin 81 projects from the upper surface of the second end portion of the rotary lever member 80. The rotation lever member 80 is rotatably supported by the base plate 28 between the first end portion and the second end portion via the rotation shaft 80b.

The rotary lever member 82 has substantially the same structure as the rotary lever member 80 except that it has a symmetrical structure. That is, the rotary lever member 82 is rotatably supported by the base plate 28 via the rotary shaft 80b, and the first end portion is rotatably connected to the connecting member 73c via the shaft pin 80a. A cover pin 85 is provided on the lower surface of the second end of the rotary lever member 82. The drive pin 83 projects from the upper surface of the rotary lever member 82 between the first end portion and the second end portion. The rotary lever member 82 is rotatably supported by the base plate 28 via a rotary shaft 80b between the first end portion and the drive pin 83.

The plurality of reference numerals 84 shown in FIG. 13 are screwing pedestal members for fixing the first link mechanism 70A and the first drive unit 71A to the first hinge base 16A and the first base portion 20A. .. These pedestal members 84 are not shown in FIGS. 11, 14, 16A and the like.

As shown in FIGS. 11 to 13, in this configuration example, one accommodating portion 30a is provided in the center of the side wall 30 of the first hinge base 16A, and one coil spring 34 is accommodated in the accommodating portion 30a. .. As a result, even in this configuration example, the slide portion 21A (21B) is constantly urged in the direction of retracting from the hinge device 16 in the X direction with respect to the hinge base 16A (16B).

As shown in FIG. 13, the rotation lever members 80 and 82 rotate about the rotation shaft 80b. Therefore, the drive pins 81 and 83 move significantly in the X direction while slightly expanding in the Y direction (see FIGS. 16A to 16C). The cover pin 85 is on the end side of the drive pin 83 with respect to the rotation shaft 80b of the rotation lever member 82. Therefore, the cover pin 85 moves greatly in the X direction while slightly expanding in the Y direction, and its operating range is larger than that of the drive pin 83 (see FIGS. 16A to 16C).

FIG. 15 is a schematic cross-sectional view of a part of the first housing 12A cut along a plane parallel to the X direction and the Z direction. In FIG. 15, the cover member 18 is not shown. As shown in FIG. 15, the drive pins 81 and 83 are slidably in contact with the pressure receiving plate 21Ac protruding from the upper plate 21Aa of the slide portion 21A (21B). The pressure receiving plate 21Ac is a wall plate extending in the Y direction (see also FIG. 11). The drive pins 81 and 83 are in contact with the surface of the pressure receiving plate 21Ac on the hinge device 16 side.

Therefore, when the rotary lever members 80 and 82 rotate and move in the direction away from the hinge device 16, the drive pins 81 and 83 slide in the Y direction with respect to the pressure receiving plate 21Ac. Press in the X direction. As a result, the slide portions 21A (21B) slide in the X direction so as to be separated from each other. The slide portion 21A (21B) slides in the direction toward the hinge device 16 side by the urging force of the coil spring 34. That is, in this configuration example, the coil spring 34 is a tension spring.

As shown in FIGS. 11 and 12, the cover pin 85 is slidably inserted into the elongated hole 88a of the cover connecting plate 88 through the cover guide hole 87 formed in the base plate 28 (FIG. 19A). reference). As shown in FIGS. 16A and 19A, the cover guide hole 87 is an arcuate elongated hole that bulges in the Y direction and extends in the X direction, and its shape corresponds to the movement locus of the cover pin 85. The cover connecting plate 88 is guided inside a rectangular frame 89 provided on the lower surface of the base plate 28, and is provided so as to be movable in the X direction. The elongated hole 88a is provided in the central portion of the cover connecting plate 88 and extends in the Y direction. A connecting pin 88b is projected from the lower surface of the cover connecting plate 88. Therefore, the connecting pin 88b is fixed to the first cover portion 18A in the same manner as the cover pin 60 shown in FIG. 9, and the first cover portion 18A is slid in the X direction. That is, the cover pin 85 is connected to the first cover portion 18A via the cover connecting plate 88.

Also in this configuration example, the second link mechanism 70B and the second drive unit 71B are arranged on the second hinge base 16B side of the hinge device 16 (reference numeral 70B shown in parentheses in FIG. 11 and the like). , 71B). The second link mechanism 70B and the second drive unit 71B have the same structure as the first link mechanism 70A and the first drive unit 71A described above, except that they have a symmetrical structure. That is, although detailed description and illustration are omitted, the second link mechanism 70B also has belt mechanism units 72, 73, drive units 74, 75, and belt drive shaft 76. The second drive unit 71B also has rotating lever members 80 and 82, drive pins 81 and 83, and a cover pin 85. The drive pins 81 and 83 are in contact with the pressure receiving plate 21Ac of the second slide portion 21B. Further, the cover pin 85 is connected to the second cover portion 18B via the cover connecting plate 88. That is, the second drive unit 71B includes the same function as the second cover drive unit 58B by having the cover pin 85.

5.2 Explanation of the operation and operation effect of the slide portion and the cover member Next, referring to FIGS. 16A to 18C, the link mechanisms 70A and 70B and the drive portion during the rotation operation of the housings 12A and 12B by the hinge device 16 The sliding operation and action effect of the sliding portions 21A and 21B and the cover member 18 by the 71A and 71B will be described.

16A to 16C are plan views schematically showing the operation of the link mechanism 70A (70B) and the drive unit 71A (71B). 16A, 16B, and 16C show states in a 0-degree posture, a 180-degree posture, and a 360-degree posture, respectively. FIG. 17A is a schematic cross-sectional view taken along the line XVII-XVII in FIG. 16A. 17A, 17B, and 17C show states in a 0-degree posture, a 180-degree posture, and a 360-degree posture, respectively. FIG. 18A is a schematic cross-sectional view taken along line XVIII-XVIII in FIG. 16A. 18A, 18B, and 18C show states in a 0-degree posture, a 180-degree posture, and a 360-degree posture, respectively. 19A to 19C are enlarged bottom views of a part of the base plate 28, showing the operation of the cover pin 85 and the cover connecting plate 88. 19A, 19B, and 19C show states in a 0-degree posture, a 180-degree posture, and a 360-degree posture, respectively.

In the following, with reference to the 180-degree posture shown in FIG. 16B, the operation of rotating from the 180-degree posture to the 0-degree posture shown in FIG. 16A and the operation of rotating from the 180-degree posture to the 360-degree posture shown in FIG. 16C are described. It will be explained in order. Although the state of the belt mechanism portion 73 is shown in FIGS. 17A to 18C, the belt mechanism portion 72 also shows substantially the same operation as shown in FIGS. 16A to 16C.

When the portable information device 10 is in the 180-degree posture shown in FIG. 8A, the drive pins 81 and 83 of the drive unit 71A (71B) are in contact with the pressure receiving plate 21Ac, respectively, as shown in FIG. 10B. .. In this state, the slide portion 21A (21B) is in a position where it slides most toward the hinge device 16 due to the urging force of the coil spring 34. The suction action between the magnet 62 and the body to be attracted 63 is the same as that of the configuration example including the link mechanism 40A (40B) and the drive unit 41A (41B).

Next, the operation when the portable information device 10 changes from the 180-degree posture shown in FIG. 8A to the 0-degree posture shown in FIG. 8D will be described. During this operation, the link mechanism 70A (70B) operates by receiving the rotation of the hinge shaft 25a (25a) as shown by the arrow in FIG. 16A.

Specifically, as shown in FIGS. 17B to 17A and 18B to 18A, the belt drive shaft 76 rotates clockwise together with the hinge shaft 25a in the drawing. Then, as shown in FIG. 17A, in the belt mechanism portion 73, the belt 73b wound downward on the belt drive shaft 76 is wound around the belt drive shaft 76, and the connecting member 73d is pulled toward the hinge shaft 25a. Therefore, as shown in FIG. 16A, the rotation link 73e rotates clockwise in the drawing due to the movement of the connecting member 73d that moves downward in the drawing. Due to the rotation of the rotation link 73e, the connecting member 73c moves on the upper side in the drawing, that is, in the direction away from the hinge shaft 25a. Therefore, as shown in FIG. 18A, the belt 73a fixed to the connecting member 73c is pulled out from the belt drive shaft 76 by the connecting member 73c.

That is, the belts 72a to 73b are flexible members. Therefore, even if the belt drive shaft 76 rotates in the direction of sending out the belts 72a to 73b, the connecting members 72c, 72d, 73c, and 73d cannot be moved because they bend on the spot. Therefore, in the case of the present embodiment, one belt mechanism portion 72 (73) is composed of a pair of belts 72a and 72b (73a, 73b), respectively, and the winding directions of both belts around the belt drive shaft 76 are the first winding and the second winding. It is different from. Further, the pair of connecting members 72c, 72d (73c, 73d) are connected to each other by the rotation link 72e (73e) so that they move in the opposite directions in the X direction. Therefore, as described above, for example, when one belt 73b is wound around the belt drive shaft 76, the other belt 73a is smoothly sent out from the belt drive shaft 76.

Then, the rotating lever member 82 connected to the belt mechanism portion 73 rotates clockwise in the drawing by moving upward in the drawing of the connecting member 73c shown in FIG. 16A. As a result, the drive pin 83 moves downward in the figure. However, as shown in FIGS. 16B and 16A, since the drive pin 83 is in contact with the surface of the pressure receiving plate 21Ac on the hinge shaft 25a side, the pressure receiving plate 21Ac is shaken without being pressed during the movement in this case. It will be.

By such an operation of the rotating lever member 82, the cover pin 85 moves downward in the cover guide hole 87 in FIG. 16B. That is, the cover pin 85 moves from the positions shown in FIGS. 16B and 19B in the direction closer to the hinge shaft 25a in the X direction. As a result, the cover pin 85 presses the cover connecting plate 88 in the X direction in the direction close to the hinge shaft 25a while moving in the elongated hole 88a. As a result, in the first cover portion 18A, the open edge portion on the side opposite to the connecting portion 18C side moves in the direction of retreating from the open edge portion of the first housing 12A. Similarly, the open edge portion of the second cover portion 18B moves in a direction in which the open edge portion retracts from the open edge portion of the second housing 12B. That is, the cover portions 18A and 18B retract to the connecting portion 18C side with the closing operation (see FIG. 4A).

On the other hand, in the belt mechanism portion 72, the belt 72b wound downward on the belt drive shaft 76 is wound around the belt drive shaft 76, and the connecting member 72d is pulled toward the hinge shaft 25a. Therefore, as shown in FIG. 16A, the rotating lever member 80 connected to the belt mechanism portion 72 rotates clockwise in the drawing by moving upward in the drawing of the connecting member 72d shown in FIG. 16A. To do. As a result, the drive pin 81 moves upward in the figure. As a result, as shown in FIGS. 16B and 16A, the drive pin 81 presses the pressure receiving plate 21Ac. As a result, the slide portions 21A (21B) slide in the direction away from the hinge device 16, that is, in the direction away from each other in the X direction, against the urging force of the coil spring 34. That is, the displays 14A and 14B move in directions that are separated from each other (see FIGS. 8A to 8D).

Next, the operation when the portable information device 10 changes from the 180-degree posture shown in FIG. 8A to the 360-degree posture shown in FIG. 8F will be described. Even during this operation, the link mechanism 70A (70B) operates by receiving the rotation of the hinge shaft 25a (25b) as shown in FIG. 16C. Specifically, as shown in FIGS. 17B, 17C, 18B and 18C, the belt drive shaft 76 rotates counterclockwise in the drawing together with the hinge shaft 25a (25b).

Therefore, as shown in FIG. 18C, in the belt mechanism portion 73, the belt 73a wound upward on the belt drive shaft 76 is wound around the belt drive shaft 76, and the connecting member 73c is pulled toward the hinge shaft 25a. Therefore, as shown in FIG. 16C, the rotary lever member 82 connected to the belt mechanism portion 73 moves downward in the drawing of the connecting member 73c shown in FIG. 16C in the counterclockwise direction in the drawing. Rotate. As a result, the drive pin 83 moves upward in the figure. As a result, as shown in FIGS. 16B and 16C, the drive pin 83 presses the pressure receiving plate 21Ac. As a result, the slide portions 21A (21B) slide in the direction away from the hinge device 16, that is, in the direction away from each other in the X direction, against the urging force of the coil spring 34. That is, the displays 14A and 14B move in directions that are separated from each other (see FIGS. 8A and 8F).

By such an operation of the rotating lever member 82, the cover pin 85 moves upward in the cover guide hole 87 in FIG. 16B. That is, the cover pin 85 moves from the positions shown in FIGS. 16B and 19B in the direction away from the hinge shaft 25a in the X direction. As a result, the cover pin 85 presses the cover connecting plate 88 in the X direction away from the hinge shaft 25a while moving in the elongated hole 88a. As a result, in the first cover portion 18A, the open edge portion on the side opposite to the connecting portion 18C side moves in the direction of advancing from the open edge portion of the first housing 12A. Similarly, the open edge portion of the second cover portion 18B moves in the direction in which the open edge portion advances from the open edge portion of the second housing 12B. That is, the cover portions 18A and 18B advance to the opposite side to the connecting portion 18C side as the opening operation is performed (see FIG. 4C).

On the other hand, in the belt mechanism portion 72, as a result of the belt 72a wound upward on the belt drive shaft 76 being wound on the belt drive shaft 76, the connecting member 72d on the belt 72b side moves upward in the drawing. Therefore, as shown in FIG. 16C, the rotary lever member 80 rotates counterclockwise in the drawing due to the movement of the connecting member 72d shown in FIG. 16C. As a result, the drive pin 81 moves downward in the drawing. Therefore, as shown in FIGS. 16B and 16C, the drive pin 81 swings without pressing the pressure receiving plate 21Ac.

As described above, in the configuration using the link mechanism 70A (70B) and the drive unit 71A (71B), as compared with the configuration using the link mechanism 40A (40B) and the drive unit 41A (41B) described above, The gears 48a to 48e of the speed reducer 43 and the rack gears 44 and 54 are not required. Therefore, when the portable information device 10 is required to be further miniaturized and thinned, the gear that has been subjected to precision processing becomes unnecessary, so that the component cost can be reduced. Further, since there is no meshing tolerance between the gears, it is possible to further reduce the deviation of the slide timing of the slide portions 21A and 21B with respect to the rotational operation of the hinge device 16.

Further, in this configuration, the cover pin 85 is provided on the rotating lever member 82 connected to the belt mechanism portion 73 side of the two sets of belt mechanism portions 72 and 73. Therefore, the drive unit 71A (71B) also functions as the cover drive unit 58A (58B), and the cover member 18 can be slid to the optimum position according to the rotational posture of the housings 12A and 12B. Although detailed description and illustration are omitted, the cover drive parts 58A and 58B that slide the cover member 18 are also driven by the belt mechanism part by newly adding a belt mechanism part different from the belt mechanism parts 72 and 73. It may be configured to be used.

6. Explanation of Link Mechanism and Drive Unit According to Second Deformation FIG. 20 is a perspective view of the first link mechanism 90A and the first drive unit 91A according to the second modification as viewed from the lower surface side. 21A is a bottom view of the first link mechanism 90A and the first drive unit 91A shown in FIG. 20. FIG. 21B is a bottom view showing the operation of the first link mechanism 90A and the first drive unit 91A when the hinge device 16 shown in FIG. 21A is rotated in the closing direction.

As shown in FIG. 20, the first link mechanism 90A has a moving portion 94. The moving portion 94 is a tongue piece-shaped plate in which a hinge shaft 25a is inserted through one edge portion. The moving portion 94 has a female screw on the inner peripheral surface of the hole portion 94a through which the hinge shaft 25a is inserted. A male screw 99 is formed on a part of the outer peripheral surface of the hinge shaft 25a, and the hinge shaft 25a meshes with the female screw of the hole 94a.

The first driving unit 91A has a pair of pressing members 95a and 95b and a driving member 96. The first ends of the pressing members 95a and 95b are rotatably supported with respect to the other edge of the moving portion 94. Most of the pressing members 95a and 95b and the moving portion 94 are arranged in the pressure receiving recess 96a formed in the driving member 96. The pressure receiving recess 96a is a notch-shaped recess with the hinge device 16 side open. The second end portion of one pressing member 95a is arranged so as to pierce the first corner portion 96b formed between the side surface in the Y direction and the side surface in the X direction forming the pressure receiving recess 96a. The second end portion of the other pressing member 95b is arranged so as to pierce the second corner portion 96c formed between the side surface in the Y direction and the side surface in the X direction forming the pressure receiving recess 96a.

The drive member 96 is a plate fixed to the lower surface of the base portion 20A of the first slide portion 21A. The drive member 96 is provided so as to be aligned with the pressure receiving recess 96a, and has a notch-shaped guide recess 96d with the hinge device 16 side open. A hinge-shaped guide plate 97 rotatably supported by the hinge shaft 25a is housed in the guide recess 96d so as to be relatively slidable in the X direction. A long hole is formed in the guide plate 97 along the X direction, and a support plate 96e protruding from the drive member 96 side is relatively slidably inserted into the long hole.

One end of the coil spring 98 is attached to both edges of the drive member 96 in the Y direction. The other end of each coil spring 98 is attached to the bridge portion 26 of the hinge device 16. The coil spring 98 constantly urges the drive member 96 toward the hinge shaft 25a.

Also in this configuration example, the second link mechanism 90B and the second drive unit 91B are arranged on the second hinge base 16B side of the hinge device 16 (see shown in parentheses in FIG. 20 and the like). See reference numerals 90B and 91B). The second link mechanism 90B and the second drive unit 91B have the same structure as the first link mechanism 90A and the first drive unit 91A described above, except that they have a symmetrical structure. That is, although detailed description and illustration are omitted, the second link mechanism 90B also has a moving unit 94. The second drive unit 91B also has pressing members 95a and 95b and a drive member 96, and the drive member 96 is fixed to the second slide unit 21B.

In such link mechanisms 90A and 90B and drive units 91A and 91B, for example, when the hinge device 16 rotates from the 180-degree posture shown in FIG. 21A to the 0-degree posture shown in FIG. 21B, the hinge shafts 25a and 25b rotate. .. As a result, the male screw 99 twists the female screw formed in the hole portion 94a of the moving portion 94, and the moving portion 94 moves to the right side in the drawing. Then, the pressing member 95a on the front side (right side in the drawing) is pressed toward the first corner portion 96b in the traveling direction of the moving portion 94. As a result, the drive member 96 receives the pressing force from the pressing member 95a and slides in the X direction away from the hinge device 16. As a result, the slide portions 21A and 21B to which the drive members 96 are fixed also slide in the direction away from the hinge device 16. The drive member 96 returns to its original position by the urging force of the coil spring 98 as the pressing force from the pressing member 95a is gradually released during the operation from the 0-degree posture to the 180-degree posture.

Further, during the operation from the 180-degree posture position shown in FIG. 21A to the 360-degree posture, for example, the moving unit 94 moves to the left side in the drawing from the position shown in FIG. 21A. Then, this time, the pressing member 95b on the front side (left side in the drawing) is pressed toward the second corner portion 96c in the traveling direction of the moving portion 94, so that the driving member 96 is separated from the hinge device 16 in the X direction. Slide in the direction. As a result, the slide portions 21A and 21B to which the drive members 96 are fixed also slide in the direction away from the hinge device 16.

As described above, even in the configuration using the link mechanism 90A (90B) and the drive unit 91A (91B), the gears 48a to 48e of the speed reducer 43 and the rack gears 44 and 54 are not required. Therefore, the portable information device 10 can reduce the component cost.

Although detailed description and illustration are omitted, the cover drive units 58A and 58B that slide the cover member 18 may be replaced by a configuration using the link mechanisms 90A and 90B and the drive units 91a and 92B. In this case, the drive member 96 continues to move in one direction in the X direction from the 0-degree posture to the 360-degree posture through the 180-degree posture, and the first cover portion 18A (or the second cover portion 18B) is gradually slid. do it.

7. Description of the portable information device according to the second embodiment 7.1 Description of the configuration of the portable information device according to the second embodiment FIG. 22 shows the portable information device 100 according to the second embodiment 180 degrees. It is a perspective view in the state of being in a posture. FIG. 23 is a partially enlarged perspective view of the portable information device 100 shown in FIG. 22 in a 0-degree posture. FIG. 24 is a partially enlarged perspective view of the portable information device 100 shown in FIG. 22 in a 360-degree posture.

As shown in FIGS. 22 to 24, the portable information device 100 has a first housing 102A and a second housing different in configuration from the housings 12A and 12B of the portable information device 10 according to the first embodiment. It comprises a body 102B. The portable information device 100 further includes a first link mechanism 104A and a second link mechanism 104B having different configurations from the link mechanisms 40A and 40B of the portable information device 10, and a first link mechanism 104A and 41B having different configurations from the drive units 41A and 41B. A drive unit 105A and a second drive unit 105B are provided.

The housings 102A and 102B have lateral view substantially trapezoidal bulging portions 106 having a plate thickness larger than that of the other portions at one edge portions 12Aa and 12Ba and their peripheral portions, respectively. Most of the thicknesses of the housings 102A and 102B are thinner than those of the housings 12A and 12B of the portable information device 10. Therefore, the housings 102A and 102B are partially provided with a bulging portion 106, and accommodate the hinge device 16, the link mechanisms 104A and 104B, and the driving portions 105A and 105B.

The moving cylinder 110a is a cylindrical member, and a hinge shaft 25a is inserted through a through hole in the axial direction thereof. The moving cylinder 110a is extrapolated so as to be movable relative to the hinge shaft 25a in the axial direction. A pin-shaped engaging piece 110c is projected from the inner peripheral surface of the moving cylinder 110a. As shown in FIG. 28, a guide groove 112 is formed on the outer peripheral surface of the hinge shaft 25a. The engaging piece 110c is slidably engaged with the guide groove 112.

FIG. 29 is a schematic view showing a configuration example of the guide groove 112 by expanding the hinge shaft 25a in the second embodiment in the circumferential direction.

As shown in FIGS. 28 and 29, the guide groove 112 is formed on the outer peripheral surface of the hinge shaft 25a, and is gradually displaced in the axial direction (Y direction) along the circumferential direction of the outer peripheral surface to form a spiral shape. doing. The guide groove 112 has a mountain shape when the hinge shaft 25a is expanded in the circumferential direction (see FIG. 29).

The guide groove 112 is composed of a top portion 112a, a first inclined portion 112b, and a second inclined portion 112c. The engaging piece 110c is arranged on the top 112a when the housings 102A and 102B are in a 180-degree posture. The engaging piece 110c moves from the top portion 112a to the first inclined portion 112b when the housings 102A and 102B rotate from a 180-degree posture to a 0-degree posture. The engaging piece 110c moves from the top 112a to the second inclined portion 112c when the housings 102A and 102B rotate from a 180-degree posture to a 360-degree posture. When the engaging piece 110c is moving on the inclined surfaces 112b and 112c, its position in the Y direction changes.

The connecting portion 110b is a plate-shaped member having a substantially J-shaped cross section that protrudes in the Y direction from the outer peripheral surface of the moving cylinder 110a. The connecting portion 110b has a guide recess 114 and a protruding piece 115. The guide recess 114 opens in the X direction on the side opposite to the moving cylinder 110a side. The edge portion of the first base portion 108A is connected to the guide recess 114 in a state of being relatively movable in the Y direction. The protruding piece 115 is a portion in which the plate portion below the guide recess 114 is projected in the X direction in the X direction on the side opposite to the moving cylinder 110a side. The projecting piece 115 is arranged on the lower surface side of the first base portion 108A. An output hole 115a extending in the X direction is formed in the projecting piece 115 (see FIGS. 25A and 27A).

As shown in FIG. 27A, a first guide hole 117, a second guide hole 118, a third guide hole 119, and a pair of fourth guide holes 120, 120 are formed in the first base portion 108A. ing.

The first guide hole 117 is provided at a position overlapping the connecting portion 110b. The first guide hole 117 is an elongated hole extending in the Y direction. A pin connecting the connecting portion 110b and the first base portion 108A is slidably inserted into the first guide hole 117. As a result, the first guide hole 117 guides the relative movement of the moving cylinder 110a with respect to the first base portion 108A. The second guide hole 118 is provided at a position adjacent to the first guide hole 117 in the X direction. The second guide hole 118 is an arc-shaped hole that extends in the Y direction and bulges toward the hinge device 16 in the X direction. The third guide hole 119 is provided at a position separated from the guide holes 117 and 118 in the Y direction. The third guide hole 119 is an arcuate hole portion extending in the X direction and bulging in the direction away from the guide holes 117 and 118 in the Y direction. Each of the fourth guide holes 120 is provided near both ends of the first base portion 108A in the Y direction. Each fourth guide hole 120 is an elongated hole extending in the Y direction. For example, two guide pins 122a are slidably inserted into each of the fourth guide holes 120. Each guide pin 122a projects from a slide plate 122 that forms a part of the first slide portion 109A.

As shown in FIGS. 26 and 27A, the first drive unit 105A has a lever member 124 and a drive pin 125.

The lever member 124 is a plate having a substantially L-shape in a plan view. The lever member 124 is provided on the lower surface side of the first base portion 108A and is rotatable in the XY plane. In the lever member 124, an L-shaped bent portion is rotatably supported by one base portion 108A via a rotation shaft 124a. The lever member 124 has a pressure receiving pin 124b projecting from the tip end portion (first end portion) on the short side side of the L shape. One end of the pressure receiving pin 124b is slidably inserted into the output hole 115a of the connecting portion 110b, and the other end is slidably inserted into the second guide hole 118. The lever member 124 has a drive pin 125 projecting from the tip end portion (second end portion) on the long side side of the L shape (see FIG. 26). The slide plate 122 fixed to the first slide portion 109A is formed with a pressure receiving hole 122b extending in the X direction. The drive pin 125 is slidably inserted into the pressure receiving hole 122b through the third guide hole 119.

As shown in FIGS. 26 and 27A, in the case of the present embodiment, the hinge device 16 has the bridge portion 26 screwed and fixed to the first base portion 108A via the fixing piece 26c. Reference numeral 128 in FIGS. 26 and 27A is a gear mechanism that synchronizes the rotational operations of the housings 102A and 102B with respect to the hinge shafts 25a and 25b. Reference numerals 129a and 129b in FIGS. 26 and 27A are torque generating units that apply a predetermined rotational torque to the rotational operation of the housings 102A and 102B with respect to the hinge shafts 25a and 25b, respectively. Reference numeral 130 in FIG. 25A is a cover plate fixed to the first slide portion 109A. The cover plate 130 covers the gap between the edge portions 12Aa and 12Ba, which expands during the rotational operation between the housings 102A and 102B, from the inside.

As shown in FIGS. 25A to 27A, a second link mechanism 104B and a second drive unit 105B are arranged on the second base portion 108B side of the hinge device 16. The second link mechanism 104B and the second drive unit 105B have the same structure as the first link mechanism 104A and the first drive unit 105A described above, except that they have a symmetrical structure. That is, although detailed description and illustration are omitted, the second link mechanism 104B also includes an input member 110. Further, the second drive unit 105B also includes a lever member 124 and a drive pin 125. The drive pin 125 of the second drive unit 105B is inserted into the pressure receiving hole 122b of the slide plate 122 fixed to the second slide unit 109B.

7.2 Description of the operation and action effect of the portable information device according to the second embodiment Next, the slide operation and action effect of the slide portions 109A and 109B when the housings 102A and 102B are rotated by the hinge device 16. Will be explained.

When the portable information device 100 is in the 180-degree posture shown in FIG. 22, the link mechanisms 104A and 104B and the drive units 105A and 105B are in the state shown in FIG. 27A. In this state, in the input member 110, the engaging piece 110c of the moving cylinder 110a is located at the top 112a of the guide groove 112 of the hinge shafts 25a and 25b (see FIG. 29). Therefore, the input member 110 is in the initial position slid to the rightmost side in FIG. 27A. Therefore, the lever member 124 of the first drive unit 105A is located at the most clockwise rotation position in FIG. 27A about the rotation shaft 124a. The lever member 124 of the second drive unit 105B is located at a position that is most rotated counterclockwise in FIG. 27A about the rotation shaft 124a.

Therefore, the drive pin 125 is in the position where it slides most toward the hinge device 16, and the slide plate 122 is also in the position where it slides most toward the hinge device 16. Therefore, the first slide portion 109A is in a position where it slides most toward the second housing 102B with respect to the hinge device 16. Similarly, the second slide portion 109B is in a position where it slides most toward the first housing 102A with respect to the hinge device 16. As a result, the housings 102A and 102B are at the closest positions where the one edge portions 12Aa and 12Ba are close to each other. Therefore, the portable information device 100 is in the large screen tablet mode.

Next, the operation when the portable information device 100 changes from the 180-degree posture shown in FIG. 25A to the 0-degree posture shown in FIG. 25C will be described. During this operation, in the link mechanisms 104A and 104B, the engaging piece 110c slides on the guide groove 112 of the rotating hinge shafts 25a and 25b. Therefore, as shown in FIGS. 27A to 27D, the input member 110 slides to the left in the drawing. Then, the lever member 124 of the first drive unit 105A is rotated counterclockwise in FIG. 27A when the pressure receiving pin 124b is pressed by the output hole 115a of the input member 110. Similarly, the lever member 124 of the second drive unit 105B rotates clockwise in FIG. 27A. Then, the drive pin 125 moves in the third guide hole 119 in a direction away from the hinge device 16 to move the slide plate 122.

As a result, in the first housing 102A, the first sliding portion 109A slides in the direction away from the second housing 102B. Further, in the second housing 102B, the first sliding portion 109B slides in a direction away from the first housing 102A. Therefore, as shown in FIGS. 25A to 25C, even in the portable information device 100, when the housings 102A and 102B are rotated, the one edge portions 12Aa and 12Ba are prevented from interfering with each other, and the housings are prevented from interfering with each other. Smooth rotation between 102A and 102B is possible.

Next, the operation when the portable information device 100 changes from a 180-degree posture to a 360-degree posture will be described. As is clear from the shape of the guide groove 112 shown in FIG. 29, the operations of the link mechanisms 104A and 104B and the drive units 105A and 105B during this operation are the same as those during the operation from the 180-degree posture to the 360-degree posture described above. is there. That is, as shown in FIGS. 27A, 27E, and 27F, the lever member 124 of the first drive unit 105A rotates counterclockwise in FIG. 27A. Similarly, the lever member 124 of the second drive unit 105B rotates clockwise in FIG. 27A. As a result, in the first housing 102A, the first sliding portion 109A slides in the direction away from the second housing 102B. Further, in the second housing 102B, the first sliding portion 109B slides in a direction away from the first housing 102A.

The slide portions 109A and 109B may not slide during the operation from the 180-degree posture to the 360-degree posture. In this case, the guide groove 112 may have a shape that does not move the second inclined portion 112c from the top portion 112a in the Y direction in FIG. 29.

As described above, when the portable information device 100 is also provided with the link mechanisms 104A and 104B and the drive units 105A and 105B, the housings 102A and 102B are closed from the 180-degree posture to the 0-degree posture. , The slide portions 109A and 109B supporting the displays 14A and 14B slide in a direction away from each other. Therefore, in the 180-degree posture, even if the housings 102A and 102B are arranged close to each other with almost no gap between them, they can be prevented from interfering with each other during rotation. As a result, even in the portable information device 100, the gap between the displays 14A and 14B in the 180-degree posture can be reduced.

Further, the link mechanisms 104A and 104B and the drive units 105A and 105B of the portable information device 100 are different from the link mechanisms 90A and 90B and the drive units 91A and 91B according to the second modification of the portable information device 10 described above. It is not necessary to use the coil spring 98 for the operation when returning to 180 degrees from the 0 degree posture or the 360 degree posture. Therefore, when the housings 102A and 102B are rotated from the 180-degree posture to the 0-degree posture or the 360-degree posture, the urging force of the coil spring 98 is applied to the engaging piece 110c or the like, and the operation load increases. Can be suppressed.

Although detailed description and illustration are omitted, the cover drive units 58A and 58B that slide the cover member 18 may be replaced by a configuration in which the link mechanisms 104A and 104B and the drive units 105A and 105B are used instead. In this case, the lever member 124 may continue to rotate in one direction from the 0-degree posture to the 360-degree posture through the 180-degree posture, and the first cover portion 18A (or the second cover portion 18B) may be gradually slid. Good.

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

In the above, the configuration including the pair of housings 12A and 12B and the pair of displays 14A and 14B is illustrated, but the configuration may include three or more housings on which the displays are mounted. For example, in the case of a three-body structure, a double-door structure or the like in which the housings are connected to both sides of the central housing by using a hinge device 16 may be used.

In the above, the configuration in which the housings 12A and 12B can rotate from the 180-degree posture shown in FIG. 4B to the 0-degree posture shown in FIG. 4A and the 360-degree posture shown in FIG. 4C is illustrated. However, even if the housings 12A and 12B are rotatable from the 180-degree posture shown in FIG. 4B to either the 0-degree posture shown in FIG. 4A or the 360-degree posture shown in FIG. 4C. Good. In this case, for example, in the portable information device 10, the shapes of the slide guide hole 51 and the cover guide hole 52 may be changed, and one of the belt mechanism portions 72 may be omitted. Further, in the portable information device 100, the shape of the guide groove 112 may be changed.

In the above, the configuration in which the slide portions 21A and 21B (109A and 109B) of both the left and right housings 12A and 12B are slid at the same time is illustrated, but only one of them, for example, the first slide portion 21A (109A) operates. The second slide portion 21B (109B) may be configured not to operate. In this case, the second link mechanism 40B, the second drive unit 40B, etc. on the second housing 12B side may be omitted, and the second slide unit 21B, etc. may be integrally fixed with the second base unit 20B, etc.

Further, in the above, the configuration in which the left and right cover portions 18A and 18B constituting the cover member 18 are slid together is illustrated, but only one of them, for example, the first cover portion 18A slides and the second cover portion 18B slides. It may be configured not to. In this case, the second cover drive unit 58B and its peripheral parts may be omitted, and the second cover unit 18B may be integrally fixed with the second housing 12B. However, a configuration in which both the first cover portion 18A and the second cover portion 18B slide is preferable to a configuration in which only one of the cover portions 18A and 18B slides. That is, in the configuration in which the cover portions 18A and 18B are slid, the design of the hinge device 16 can be standardized between the left and right housings 12A and 12B, and the hinge device 16 slides the cover portions 18A and 18B. The required distance can be shortened to reduce the size of the hinge device 16.
