The communication between the keyboard 12 and the tablet terminal 14 may be either wired or wireless. The keyboard 12 may include a pointing device such as a touch pad or other input / output device. The tablet terminal 14 and the keyboard 12 are also applied to the keyboard support devices 10B and 10C described later.

(First Embodiment)
Next, the keyboard support device 10A according to the first embodiment will be described. The keyboard support device 10A supports a separate keyboard 12 with respect to the tablet terminal 14. For each "hinge" in the following description, the bending axis shall be lateral unless otherwise specified. Each hinge is, for example, a fabric hinge.

The keyboard support device 10A includes an upper plate 24 on which the keyboard 12 is mounted on the upper surface, a mounting plate 28 mounted on the mounting surface 26, a back plate 30, legs 32, and auxiliary legs 34. To prepare for. The mounting surface 26 does not have to be an accurate horizontal plane. The back plate 30 is provided with a stand 35, and can support the back surface of the tablet terminal 14. The stand 35 is foldable. The stand 35 may be detachable from the back plate 30. The stand 35 may be configured so that the angle of the back plate 30 can be adjusted. The upper plate 24 may be provided with positioning means (for example, magnets, protrusions, recesses, etc.) for the keyboard 12. The upper plate 24, the mounting plate 28, and the back plate 30 each have substantially the same shape, the horizontal width is substantially the same as that of the keyboard 12, and the vertical width is equal to or slightly larger than the thickness of the tablet terminal 14. The width of the legs 32 is equal to that of the upper plate 24, the mounting plate 28, and the back plate 30, and the vertical width is equal to or slightly larger than the height of the tablet terminal 14. The upper plate 24, the mounting plate 28, the back plate 30, the leg portion 32, and the auxiliary leg portion 34 are, for example, resin materials, are thin and lightweight, and have appropriate strength.

The upper plate 24 and one end of the leg portion 32 are connected by an upper hinge 38. The mounting plate 28 and the other end of the leg portion 32 are connected by a lower hinge 36. The back plate 30 and the mounting plate 28 are connected by a rear hinge 40. The auxiliary leg portion 34 is formed in a portion closer to the front of the upper plate 24, and the rear portion is connected to the upper plate 24 by an auxiliary hinge 42. A leg-side magnet 34a is provided at the front end of the auxiliary leg portion 34. A leg maintenance magnet 36a is provided at the contact portion at the tip of the auxiliary leg portion 34 in the first state described later.

By the way, three main states can be considered in the mode of inputting to the tablet terminal 14 using the keyboard 12. First, the keyboard 12 is not mounted on any part of the tablet terminal 14, and there is a state in which the arrangement is not mutually restricted (see FIGS. 1, 2, and 3). In the present application, this is referred to as a third state.

Next, it is conceivable that the entire vertical direction of the keyboard 12 is placed on the tablet terminal 14 (see FIG. 4). In the present application, this is referred to as a second state. In the second state, for example, the keyboard 12 is arranged on the second housing 20. In this state, the exposed portion of the first housing 18 of the display 22 becomes effective, and the portion of the second housing 20 is covered by the keyboard 12.

Further, it is conceivable that the rear portion of the keyboard 12 is placed on a part of the tablet terminal 14, and the front portion of the keyboard 12 protrudes to the front side of the tablet terminal 14 (see FIGS. 6 and 5). In the present application, this is referred to as a first state. In this state, the portion of the first housing 18 and the rear side portion of the second housing 20 of the display 22 are exposed and effective, and only the front side portion of the second housing 20 is covered by the keyboard 12. In the first state, the effective display area of the display 22 can be expanded as compared with the second state.

The keyboard support device 10A according to the first embodiment has specifications corresponding to the above three states. Hereinafter, the operation of the keyboard support device 10A in each of the third state, the second state, and the first state will be described. In each state, the keyboard 12 is placed at a predetermined position on the upper surface of the upper plate 24. In other words, the upper plate 24 may be integrated with the lower surface of the keyboard 12.

FIG. 3 is a schematic side view of the keyboard support device 10A, the keyboard 12, and the tablet terminal 14 in the third state. As shown in FIGS. 1 to 3, in the third state, the leg portion 32 is folded by the upper hinge 38, and the mounting plate 28 and the leg portion 32 are folded over the upper plate 24. That is, the legs 32 are in a folded posture along the lower surface of the keyboard 12. Since the lower surface of the auxiliary leg portion 34 is supported by the mounting plate 28, the auxiliary leg portion 34 is housed in the upper plate 24. The back plate 30 is bent at an appropriate angle with respect to the mounting plate 28 by the back hinge 40. The back surface of the tablet terminal 14 is supported by the back plate 30, and the lower end portion is fitted between the end portion of the upper plate 24 and the lower end portion of the back plate 30 to be stable. The angle of the back plate 30 is maintained by the stand 35 so that the display 22 of the tablet terminal 14 faces the user's face.

In this third state, the entire surface of the display 22 in the tablet terminal 14 can be used, and the tablet terminal 14 can be held at an appropriate angle. As described above, the keyboard support device 10A also has a function of holding the tablet terminal 14. Although the tablet terminal 14 is placed horizontally in FIG. 1, the tablet terminal 14 is stably held by the stand 35 even when the tablet terminal 14 is placed vertically.

Further, when the tablet terminal 14 is removed and the back plate 30 is folded by the back hinge 40 in this third state, the keyboard 12 is sandwiched between the back plate 30, the upper plate 24, and the mounting plate 28. Therefore, the keyboard support device 10A can be used as a cover for the keyboard 12.

FIG. 4 is a schematic side view of the keyboard support device 10A, the keyboard 12, and the tablet terminal 14 in the second state. In the second state, the second housing 20 of the tablet terminal 14 is inserted between the upper plate 24 and the mounting plate 28, and the first housing 18 is supported by the back plate 30 to be stable. The back plate 30 is maintained at an appropriate angle by the stand 35 as in the third state (see FIG. 3). The hinge portion 16 of the tablet terminal 14 is located at a portion corresponding to the rear hinge 40.

In the second state, the lower hinge 36 is appropriately bent and the upper hinge 38 is appropriately expanded so that the leg portion 32 is separated from the upper plate 24. That is, in the second state, the leg portion 32 is switched to a downward protruding posture that protrudes downward from the lower surface of the keyboard 12. At this time, the lower surface of the keyboard 12 is also supported by the legs 32, but is mainly supported by the second housing 20 via the upper plate 24.

The downward protruding posture in the present application means that a part of the keyboard 12 is projected downward directly from the lower surface (including the extension surface thereof) of the keyboard 12 or via the upper plate 24 or the like to the extent that a part of the keyboard 12 can be supported. Show posture. The downward protruding posture includes a vertical orientation, but may be slightly tilted from the vertical depending on the design conditions (see FIG. 5).

The front end portion of the second housing 20 reaches a position where it abuts on a part of the leg portion 32. The leg portion 32 acts as a positioning portion that limits the entry of the second housing 20 to the front side. The entire length of the keyboard 12 in the vertical direction is arranged on the upper surface of the second housing 20 via the upper plate 24, and the upper plate 24 protects the display 22. Since the lower surface of the auxiliary leg portion 34 is supported by the second housing 20, the auxiliary leg portion 34 is housed in the upper plate 24.

In such a second state, the tablet terminal 14 and the keyboard 12 can be combined to display the screen and input characters in the same manner as a general notebook PC provided with a physical keyboard. In addition, the vertical dimension is suppressed and it can be used in narrow places.

FIG. 5 is a schematic side view of the keyboard support device 10A, the keyboard 12, and the tablet terminal 14 in the first state. FIG. 6 is a partially exploded perspective view of the keyboard support device 10A, the keyboard 12, and the tablet terminal 14 in the first state.

In the first state, the rear part of the keyboard 12 is placed on a part of the second housing 20 of the tablet terminal 14 via the upper plate 24, but the front part of the keyboard 12 is in front of the tablet terminal 14. It stands out. That is, in the first state, the leg portion 32 is in a downward protruding posture as in the second state. Since the second housing 20 does not exist below the front portion of the keyboard 12, the upper plate 24 is mainly supported by the legs 32.

The second housing 20 supports only the rear side portion of the keyboard 12 and the upper plate 24, and a space 43 is formed in the front side portion. Then, since the auxiliary leg portion 34 provided on the front side of the upper plate 24 has no supporting means downward, the auxiliary leg portion 34 is inclined downward with respect to the auxiliary hinge 42 and the tip abuts on the lower hinge 36. A leg-side magnet 34a is provided at the tip of the auxiliary leg portion 34, and a leg-maintaining magnet 38a is provided at the abutting portion thereof. Will support the lower surface of the keyboard 12.

Further, even if the user does not perform any special operation on the auxiliary leg portion 34, the auxiliary leg portion 34 is tilted downward due to its own weight and the magnetic force. Since the upper plate 24, the leg portion 32, and the auxiliary leg portion 34 form a triangle when viewed from the side, the keyboard 12 which is hard to be deformed can be reliably supported. The triangle formed by the upper plate 24, the leg portion 32, and the auxiliary leg portion 34 in a side view is stabilized by being configured such that the portion having the lower hinge 36 as the apex is at a right angle, for example. In this case, the leg portion 32 has an inclination such that the upper end thereof is slightly forward.

Depending on the design conditions, the position where the tip of the auxiliary leg portion 34 abuts in the first state is not limited to the lower hinge 36, and the keyboard 12 can be supported if it abuts on a part of the mounting plate 28. .. A notch 44 (see FIG. 5) is formed in the storage area of the auxiliary leg portion 34 in the upper plate 24 by inclining the auxiliary leg portion 34 downward, but even if the notch 44 is covered with a thin film or the like. good. As a result, the design is improved and the auxiliary leg portion 34 is prevented from protruding upward. Even if the auxiliary leg portion 34 is omitted due to the design conditions, the appropriate stability can be obtained only with the leg portion 32. When the auxiliary leg portion 34 is omitted, the leg portion 32 in the first state may be set to face vertically.

The rear end portion of the second housing 20 is arranged on the rear side of the rear hinge 40, and the back plate 30 is arranged in contact with the mounting surface 26 together with the mounting plate 28. The first housing 18 maintains an inclined posture by the frictional force of the hinge portion 16.

When the second housing 20 is pulled out from between the upper plate 24 and the mounting plate 28 from the first state, the upper hinge 38 bends due to the weight of the keyboard 12, and is mounted on the upper plate 24 in the same manner as in the third state. The plate 28 and the leg 32 overlap each other. At this time, even if the user does not perform any special operation on the leg portion 32 and the auxiliary leg portion 34, the leg portion 32 is in the folded posture and the inclined auxiliary leg portion 34 is again in the notch 44 of the upper plate 24. It is stored inside. When the second housing 20 is pushed forward from the first state, the auxiliary leg portion 34 whose tip portion is inclined is pushed up, and the auxiliary leg portion 34 is again notched in the upper plate 24. It is stored in 44 and shifts to the second state.

In such a keyboard support device 10A, in the first state (see FIG. 5), the legs 32 are in a downward protruding posture to support the lower surface of the front side portion of the keyboard 12, and the keyboard 12 is stably arranged. Then, in the first state, the portion of the display surface of the display 22 that covers the second housing 20 is considerably exposed and can be effectively used. Further, in the third state (see FIG. 3), the leg portion 32 is in the folded posture, the upper plate 24 and the mounting plate 28 are overlapped with each other with almost no gap, and no wasted space is generated, so that the keyboard 12 can be arranged at a low position.

Further, the user can insert and remove the second housing 20 between the upper plate 24 and the mounting plate 28, and can switch between the first state, the second state, and the third state depending on the insertion depth thereof.
