1 to 5 show an embodiment of the present invention. The information processing device is a device main body 1 having a keyboard operation unit 10 formed of a key top matrix on the upper surface.
And a display operation unit 2 having a display panel such as a liquid crystal display device on one surface. The device body 1 is a keyboard operation unit 10
Has guide walls 11 on both sides thereof, and the control board 11a is accommodated in the guide walls 11. The guide groove 3 is arranged substantially parallel to the surface of the keyboard operating unit 10.

The widthwise dimension of the display / operation unit 2 is the guide wall 1.
The space between the shafts 1 and 11 is almost equal, and a hollow cylindrical shaft fulcrum 4 is provided at one end of both wall surfaces of the shaft support 4. The shaft fulcrum 4 is fitted in the guide groove 3, and the display operation unit 2 is rotatable about the shaft fulcrum 4 and slidable along the guide groove 3 in the apparatus main body 1
Connected to. The axis fulcrum 4 is arranged on the center line C in the thickness direction of the display operation unit 2 so that the display operation unit 2 can be inverted to the use posture of the display operation unit as described later (see FIG. 2B). Further, the display lower end edge 21 of the display operation section 2 and its opposite side edge are curved surfaces concentric with the axis fulcrum 4 so that interference with the display operation section 2 does not occur when rotating around the axis fulcrum 4. Is desirable. A control board (not shown) of the display panel arranged in the display operation section 2 and a control board 11a on the apparatus main body 1 side are connected by a flexible cable 5 which passes through the hollow portion of the shaft fulcrum 4.

Therefore, in this embodiment, when the information processing apparatus is not used, as shown in FIG. 2, the shaft fulcrum 4 is located at the stroke rear end position, that is, the apparatus main body 1.
And is stacked on the apparatus main body 1 in a state of being positioned near the rear position of. In this state, since the back surface 22 of the display operation unit 2 is exposed to the outside, the display surface 20 is not damaged during transportation or the like.

From this state, as shown in FIG. 3, when the display operation unit 2 is rotated in the direction of the arrow without being moved to stand upright, the keyboard operation unit 10 is exposed to the outside, and the keyboard operation unit 10 is exposed. By operating 10, the processed data can be displayed on the display operation unit 2 or a data processing operation can be performed using a pen (not shown) on the display operation unit 2 (keyboard use posture). As shown in FIG. 5, an elastic locking claw 30 is formed at the stroke rear end position of the guide groove 3, and is formed on the outer periphery of the shaft fulcrum 4 when the shaft fulcrum 4 is located at that position. The engagement recess 41 is locked. The engagement concave portions 41 are arranged at a predetermined pitch angle, and when the display operation unit 2 is rotated, the locking position is changed and the display operation unit 2 is maintained at a desired inclination angle. This state corresponds to the normal use posture of a laptop computer or the like.

From the above posture, as shown in FIG.
Sliding the guide along the guide groove 3 toward the front to position the shaft fulcrum 4 at the stroke front end position, and then rotating the display operation unit 2 backward as indicated by an arrow in FIG. 4 (a). As shown in FIGS. 4B and 4C, the display operation unit 2 can be stacked on the apparatus main body 1. In this posture in which the display operation unit 2 is inverted from the above-described non-use posture, the keyboard operation unit 10 is covered with the display operation unit 2, and the display surface 20 of the display operation unit 2 is exposed on the surface of the information processing device. Therefore, various operations can be performed by operating the display surface 20 of the display operation unit 2 with a pen. Since the keyboard operation unit 10 is not exposed to the outside when the display operation unit 2 is operated, the keyboard is not accidentally pressed. Further, after reversing the display operation unit 2 from this posture, and sliding the shaft fulcrum 4 to the stroke rear end position, the posture can be easily changed to the non-use posture. As shown in FIGS. 2, 3, and 4, the rotation of the display operation unit 2,
Since the flexible cable 5 is only displaced in the folding direction during the sliding operation, the flexible cable 5 is not broken.

In the above description, the display operation unit 2
Shows that the shaft fulcrum 4 can be rotated about the shaft fulcrum 4 at any position in the guide groove 3, but it is sufficient if the shaft fulcrum 4 can be rotated only at the stroke rear end position.

Further, in the above-mentioned embodiment, the case where the engaging claw 30 and the engaging concave portion 41 are combined is shown as an angle stopper for maintaining the display operating portion 2 at an arbitrary inclination angle. In addition, various mechanisms can be adopted. FIG. 6 shows an example thereof, in which the shaft fulcrum 4 is formed in a shape such that it cannot idle with respect to the guide groove 3 and is slidable along the guide groove 3, for example, an oval shape. A torque hinge 8 that can be maintained at an arbitrary angle is incorporated in the display operation unit 2, and one end of the torque hinge 8 is fixed to the shaft fulcrum 4. In addition, in the present modification and other modifications described below, or in the description of other embodiments, components that are essentially the same as those of the above-described embodiments are denoted by the same reference numerals in the drawings. And the description is omitted.

When a rotational torque is applied to the display / operation unit 2 in the above modification, a relative rotational displacement occurs between the fixed end of the torque hinge 8 to the display / operation unit 2 and the fixed end to the shaft fulcrum 4. Since the torque hinge 8 can maintain the original rotation posture against a predetermined rotation torque, the display operation unit 2 rotated by an appropriate angle maintains the inclined posture.

7 and 8 show another modification. This modified example improves the usability by moving the keyboard operating unit 10 up and down, and the keyboard operating unit 10 is supported on a lifter 12 housed in the apparatus main body 1.
The lifter 12 is a frame member having a U-shaped cross section that is housed in the apparatus body 1 so as to be movable in the front-rear direction, and has a V-shaped notch 12a at the front-rear end of the opposing side wall. A lever 13 whose upper end is exposed on the surface of the apparatus main body 1 is connected to the rear end of the lifter 12. The lever 13 is rotatably supported by the apparatus main body 1. When the lever 13 is rotated in the direction of the arrow in FIG. 7A, the lifter 12 moves forward. A notch 12a is formed on the support shaft 10a that is provided on the side edge by the movement of the lifter 12.
The keyboard operation unit 10 placed on the lifter 12 and supported on the lifter 12 receives an upward force by the inclined surface of the notch 12a and moves upward as shown in FIG. 7B. This posture corresponds to the operation position by the keyboard operation unit 10, and again the lever 13 is rotated in the opposite direction to accommodate the support shaft 10a in the notch 12a, and the keyboard operation unit 10 is moved to the lower position to display the operation unit. Two sliding spaces are secured. Note that in FIG. 7, reference numeral 15 denotes a stopper that regulates the vertical movement stroke of the keyboard operating unit 10.

It should be noted that, in the above-described modification, the up / down operation of the keyboard operation unit 10 is performed by manually operating the lever 13, but it can be automatically operated by configuring as shown in FIG. That is, in the modified example shown in FIG. 9, the lever operation protrusion 42 is provided so as to project from the shaft fulcrum 4, and the tip of the lever 13 projects into the traveling path of the shaft fulcrum 4. The lever operation protrusion 42 is formed in a shape that does not interfere with the tip of the lever 13 when the display operation unit 2 moves in a posture parallel to the keyboard operation unit 10 and interferes in the rotation posture.

The lifter 12 is biased toward the front end side of the apparatus main body 1 by a tension spring 14, and at this position, the support shaft 10a of the keyboard operating portion 10 is shown in FIG. 9 (a).
As shown in FIG. Further, the lever 13 maintains the upright posture, and the display operation unit 2 takes the posture in which the display surface 20 is directed to the keyboard operation unit 10 side. When the display operation unit 2 is rotated rearward about the shaft fulcrum 4 from this state, the lever operation protrusion 42 interferes with the tip of the lever 13 as shown in FIG.
Is rotated in the direction of the arrow in FIG. 9 (b). Due to the rotation of the lever 13, the lifter 12 moves rearward against the reaction force of the tension spring 14, and the support shaft 10a rides on the inclined surface of the notch 12a, so that the keyboard operation unit 10 rises.
By maintaining the inclination angle of the display operation unit 2 at an appropriate angle, work using the keyboard operation unit 10 becomes possible. After that, when the display operation unit 2 is further rotated as shown in FIG. 10, the lever operation protrusion 42 moves over the tip of the lever 13 and moves to the front of the lever 13 to release the interference state of both. The lifter 12 that has lost the barrier returns to the original position by the restoring force of the tension spring 14, and the lever 13 that receives the force of the tension spring 14 via the pressing pin 13a also returns to the original position. When the lifter 12 returns to the original position, the support shaft 10a falls again into the notch 12a, and the height of the keyboard operation unit 10 becomes low. Figure 10
As shown in FIG. 10A, the traveling path of the shaft fulcrum 4 is opened due to the sinking of the keyboard. Therefore, when the shaft fulcrum 4 is moved to the front end side of the stroke, as shown in FIG. It is possible to shift to the use posture of the display operation unit located on the surface. Further, when the shaft fulcrum 4 is moved rearward again from the use posture of the display operation unit and then the display operation unit 2 is rotated forward as shown in FIG. 11, the lever operation protrusion 42 causes the lever 13 to move the lever 13 in the counterclockwise direction. Rotate. Since the pressing direction of the lever 13 in this state does not actuate the pressing pin 13a as shown in FIG. 11 (b), the lever operating protrusion 42 does not operate the keyboard operating unit 10 to raise the lever 13 only. After rotating once, it goes around the back surface of the lever 13. In this state, since the keyboard operating unit 10 is in the sinking posture, the display operating unit 2 is further rotated backward to be in a parallel posture with the apparatus main body 1, and when the display operating unit 2 is moved in parallel to the forward posture, it is in a non-use posture. Transition.

FIG. 12 shows a reference example . In this reference example , a vertically long slot 16 is formed at the rear end of the apparatus body 1,
A shaft portion 73 formed at one end of the stay 7 is slidably and rotatably fitted. The stay 7 has an appropriate width W, corresponds to the back wall of the apparatus main body 1, and has the shaft portion 73 at the lower end.
The apparatus main body corresponding portion 70 including the display operating portion 2 and the display operating portion corresponding portion 71 whose tip corresponds to the back surface of the display operating portion 2 and is rotatably attached to the central portion of the display operating portion 2 and has an L-shaped cross section. Is formed into a plate shape. Further, as described above, the flexible cable 5 is inserted through the central portion of the shaft fulcrum 4.

In this reference example , when not in use, the back surface 22 of the display operation unit 2 is exposed to the outside as shown in FIG. 12, and the display surface 20 is protected. In this state, the shaft portion of the stay 7 is located at the upper end of the elongated hole 16, and the stay main body corresponding portion 7
Since the wide surface 7a of 0 is along the rear wall of the apparatus main body 1 and the wide surface 7a of the display / operation unit corresponding portion 71 is along the back surface of the display / operation unit 2, the stay 7 becomes an obstacle during transportation or the like. In addition, there is no sense of discomfort in terms of design.

When the keyboard operating unit 10 is used, the display operating unit 2 is rotated by causing the leading edge of the display operating unit 2, that is, the front side edge, as shown in FIG. Since the shaft portion 73 is movable in the elongated hole 16, the rotation of the display operation unit 2 is not hindered, and the keyboard operation unit can be used. If a plurality of recesses are formed in the position of the shaft fulcrum 4 in the posture of using the keyboard operation unit, that is, near the stroke end position, the display operation unit 2 is erected by engaging the shaft fulcrum 4 with the recesses at appropriate positions. Can hold posture.

In this state, the wide surface 7a of the stay 7 is separated from the display operation section 2 and the rear wall of the apparatus main body 1, but the stay 7 is separated from the display operation section 2 and the apparatus main body 1.
Since it is narrower than the width dimension and is arranged at the center in the width direction, it does not appear hidden behind the display operation unit 2 to the user, and there is no visual annoyance.

When the shaft fulcrum 4 is slid forward from the use posture of the keyboard operation unit 10, the display operation unit 2 rotates as shown in FIG. 14, and when the shaft fulcrum 4 reaches the stroke front end position. The display operation unit 2 is stacked on the apparatus body 1 with the display surface 20 facing upward. In this state, the shaft portion 73 of the stay 7 is located at the lower end of the elongated hole 16, the wide surface 7a of the device body corresponding portion 70 extends along the back wall of the device body 1, and the wide surface of the display operation portion corresponding portion 71. 7 a is located between the back surface 22 of the display operation unit 2 and the front surface of the keyboard operation unit 10. In the operation posture of the display operation unit 2,
Since the stay 7 is integrated without protruding, the entire information processing device can be easily grasped and workability is improved. In the description of the present embodiment, the up / down operation of the keyboard operation unit 10 is not mentioned, but the above-described configuration can be applied as it is.

FIG. 15 shows a second embodiment of the present invention. In this embodiment, the shaft fulcrum 4 is formed on the apparatus body 1 side. A shaft forming wall 17 is formed at the rear end side edge of the device body 1 so that the shaft forming wall 17 can be fitted into the guide groove 3 formed in the side wall of the display operation portion 2, and the shaft fulcrum 4 projects from the shaft forming wall 17. Set up. A flexible cable 5 that connects the display operation unit 2 and the apparatus main body 1 is inserted into the shaft fulcrum 4.

Therefore, in this embodiment, in the non-use posture, as shown in FIG.
Appears outside and the display surface 20 is protected. When the display operation unit 2 is rotated around the shaft fulcrum 4 from this state, the operation posture by the keyboard operation unit 10 shown in FIG. 16 is entered. In order to fix the display operation unit 2 at an appropriate inclination angle, the angle stopper mechanism shown in FIG. 5 or 6 is configured around the shaft fulcrum 4. When the display operation unit 2 is further rotated rearward from the work posture by the keyboard operation unit 10, the display operation unit 2 becomes parallel to the apparatus main body 1. After that, when the display operation unit 2 is moved in parallel to the front side, As shown in 17, the display surface 20 of the display operation unit 2 appears on the surface, and in this state, the operation using the display operation unit 2 becomes possible.

In this embodiment, since the guide wall 11 does not project to the side edge of the keyboard operating portion 10, the surface of the keyboard operating portion 10 is flat over the entire surface, which facilitates keyboard operation. Since the display operation unit 2 can also have the same area as the device main body 1, the display surface 20 can also be wide.

A second reference example is shown in FIGS. this
In the reference example , the shaft forming wall 17 is provided on the side edge of the rear end of the apparatus body 1.
Is formed, and the shaft fulcrum 4 is provided so as to project inward. At the shaft fulcrum 4, rolling elements 40 (main
In the reference example , a pinion is mounted, and a stopper cylinder 43 having an appropriate number of locking recesses 43a formed on the outer periphery is formed at the tip of the shaft fulcrum 4. The shaft fulcrum 4 and the stopper cylinder 43 are integrally formed. An elastic locking claw 30 is arranged at the end position of the movement path of the stopper cylinder 43. The locking claw 30 is formed integrally with the display operation unit 2. The shaft fulcrum 4 is inserted into the display operating part 2 through a shaft insertion opening 23 formed in the side wall of the display operating part 2 and long in the depth direction, and the rolling element 40 is formed in the display operating part 2 with a rolling path 6 ( In this reference example, it rolls on a rack).

Therefore, in this reference example , the rack 6 is located below the pinion 40 and meshes with the pinion 40 in the display operating portion use posture as shown in FIG. In order to shift from this state to the use posture of the keyboard operation unit, the display operation unit 2 is once slid backward. The parallel movement of the display operation unit 2 causes the locking claw 30 of the display operation unit 2 to be locked in the locking recess 43a of the stopper cylinder 43 (FIG. 21).
(See (a)). After that, when the display operation unit 2 is rotated in the direction of the arrow in FIG.
21A, the display operating unit 2 is maintained in a desired tilted posture in the locked state (keyboard operating unit using posture) by rotating around the shaft fulcrum 4 while successively getting over the locking concave portion 43a. .

Since the locking recess 43a of the stopper cylinder 43 is arranged only from the front surface side to the bottom surface side of the apparatus main body 1, even if the display operation unit 2 is further rotated thereafter, the locking state is not obtained. , It becomes possible to smoothly shift to the non-use posture. To shift to the non-use posture shown in FIG. 22, the display operation unit 2 may be further rotated to be in the posture parallel to the apparatus main body 1, and the display operation unit 2 may be superposed on the apparatus main body 1.

FIG. 23 shows a modification of the second reference example . In this modification, a stopper plate 44 parallel to the rack 6 is integrally provided at the tip of the shaft fulcrum 4. The shaft fulcrum 4 is attached to the shaft forming wall 17 via a torque hinge 8,
It can be stationary at an appropriate rotation angle with respect to the apparatus body 1. In addition, a U-shaped fitting 24 that is opened from the display lower end edge 21 toward the opposite end and that can be fitted to the stopper plate 44 is fixed to the display operation unit 2. When the display operation unit 2 is moved backward from the display operation unit use posture shown in FIG. 23,
The fitting 24 is fitted to the stopper plate 44 of the shaft fulcrum 4. When the display operation unit is rotated from this state, the fitting 2
The shaft fulcrum 4 fitted in 4 is also rotated, and is held at an arbitrary inclination angle by the action of the torque hinge 8 to be in the keyboard operating portion use posture shown in FIG.
When is rotated and stacked on the apparatus main body 1, it shifts to an unused posture.

FIG. 24 shows a third reference example of the present invention. In this reference example , a shaft fulcrum 4 is provided on a shaft forming wall 17 formed on a rear side edge of the apparatus body 1 via a torque hinge 8. A rolling element (pinion) is mounted on the shaft fulcrum 4 so as to be free to rotate, as in the above-described embodiment. Display operation unit 2
The inner rolling path 6 (rack) is formed so that the display lower edge 21 side is slightly shorter than the moving stroke of the pinion 40. Further, the end on the display lower end edge 21 side is movable in the vertical direction, that is, in the thickness direction of the display operation unit 2, and is biased toward the display surface 20 side by the compression spring 26. The side of the rolling path 40 opposite to the display lower edge 21 is fixed, and the biasing side end moves to the display surface 20 side by contacting the push button 25 whose head 25a is exposed on the display surface 20 side. Is regulated. The push button 25 is arranged near the center of the display device 2 by the rack 6 so that the push button 25 does not interfere with the rolling path of the pinion 40.
Is abutted against the push button 25. Push button 2
The end of the rack 6 on the biased side is held at a height in the vicinity of the center of the pinion 40 while being in contact with the rack 5. The second reference
The same components as those of the example are indicated by the same reference numerals in the drawings.

In this reference example , the shaft fulcrum 4 is located on the fixed end side of the rack 6 in the use posture of the display operation unit shown in FIG. 24, and the display operation unit 2 rotates around the shaft fulcrum 4 and the apparatus main body 1 Translation along is allowed. When the display operation unit 2 is moved in parallel, the shaft fulcrum 4 moves relatively while pushing the rack 6 against the urging force of the compression spring 26 toward the back surface 22 side of the display device 2 and stops at the stroke end position. 44 is fitted to the fitting 24.
Since the rack 6 is short, it is detached from the pinion 40 in the vicinity of the stroke end position and, as shown in FIG. 25 (a), the urging side of the rack 6 returned to the original position by the restoring force of the compression spring 26. The tip faces the pinion 40. In this state, the tip of the rack 6 on the biasing side functions as a stopper 60 for preventing the parallel movement of the pinion 40. From this state, push the push button 25 and push the rack 6
Is moved downward to open the rolling path of the pinion 40, the display operation unit 2 can be returned to its original position.

Thereafter, when the display / operation section 2 is rotated in the direction of the arrow in FIG. 25 (a), the shaft fulcrum 4 fitted to the fitting 24 is shown.
Also rotates together and shifts to the keyboard operating portion use posture shown in FIG. In the posture of using the keyboard, the display operation unit 2 is maintained at an arbitrary inclination by the torque hinge 8.

After that, when the display / operation unit 2 is further rotated and stacked on the apparatus main body 1, it shifts to the non-use posture. As described above, since the rolling path of the pinion 40 is blocked by the stopper 60 in the non-use posture, the display operation unit 2 is reliably prevented from sliding carelessly during transportation or the like. Further, the push button exposes the operation head on the display surface 20 side and pushes it against the reaction force of the compression spring 26 to release the stopper 60 of the rack 6, so that the push button is pushed to the outside in a non-use posture. No exposure, no accidental push button operation.

In the second and third reference examples , the pinion is used as the rolling element 40 and the rack is used as the rolling path 6, but the rolling element 40 may be a roller. In this case, the rolling path 6 can be formed as a flat surface.

27 and 28 show a fourth reference example. In this reference example, the apparatus main body 1 and the display operation unit 2 are connected by a wide stay 7. The stay 7 has the same shape as that used in the above reference example, and the flexible cable 5 that connects the control board 11a in the apparatus main body 1 and the control board of the display operation unit 2 is inserted through the stay 7. The wide stay 7 can provide a sufficient accommodation space for the wide and thin flexible cable 5.

In this reference example , in the non-use posture shown in FIG. 27 (a), the wide surface 7a of the stay 7 is along the back surface 22 and the back wall of the display operation section 2 and does not interfere. When the display operation unit 2 is moved upward while rotating the stay 7 and stopped at an appropriate position, the keyboard operation unit is in the use posture (see FIG. 27B). In order to fix the inclination angle of the display operation unit 2, the stay 7 and the display operation unit 2,
The connecting portion with the apparatus body 1 can be fastened with, for example, a set screw. From this state, as shown in FIG. 28, when the display operation unit 2 is further rotated and the stay 7 is rotated in the folding direction, the display operation unit 2 can be stacked on the apparatus main body 1 and the display operation unit use posture. Transition. Since the stay 7 is housed on the back surface 22 of the display operation unit 2 in the use posture of the display operation unit, it does not hinder work such as input.

29 to 31 show modified examples of the above reference example . In this modification, the wide stay 7 is rotatably connected to a hinge piece 18 formed at the rear end of the apparatus body 1. The other end of the stay 7 is slidably and rotatably connected to the back surface 22 of the display operation unit 2 via a sliding hinge 74. The stay 7 has a rotary node 72 in the middle portion thereof, and the short stay portion 75 connected to the apparatus body 1 side is positioned along the back surface of the apparatus body 1 in a height position of the back surface 22 of the display operation unit 2. The length is located at.

Therefore, in this modified example , FIGS.
