Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a writing device such as a desktop or laptop word processor and a portable computer, and more particularly to a structure for rotatably connecting a display unit to a base housing. .

[0002]

2. Description of the Related Art A desktop or laptop word processor includes a base housing having a keyboard and a display unit having a flat display screen.

The base housing has a front half portion in which a keyboard is incorporated on the upper surface and a rear half portion in which a printer and a floppy disk drive are built. The rear half of the base housing projects above the keyboard, and the display unit is connected to the boundary between the rear half and the front half. The display unit includes a closed position in which the keyboard is laid down substantially horizontally so as to cover the keyboard from above, and an open position in which the display screen is erected behind the keyboard and the keyboard can be operated while watching the display screen. It is possible to rotate in the front-back direction over the space.

By the way, in the conventional word processor,
In order to rotatably connect the display unit to the base housing in the front-rear direction, a pair of left and right support walls are provided on the upper surface of the base housing so as to project. The support wall is located at the boundary between the front half and the rear half of the base housing, one end of the display unit is interposed between the support walls, and is connected via a hinge shaft extending in the left-right direction. Has been done.

With this connection, the display unit can rotate about the hinge shaft as the center of rotation between the open position and the closed position. And
When the display unit is rotated to the open position, the operator can freely adjust the standing angle so that the display screen can be viewed most easily.

[0006]

However, according to the conventional word processor, since the angle of the display unit can be adjusted only in the front-back direction, for example, depending on the position of the office lighting or the incident direction of outdoor light,
Illumination light and outdoor light may be reflected on the display screen, making it difficult to see the display screen.

Therefore, in the case where the reflection of light on the display screen cannot be eliminated only by adjusting the standing angle of the display unit, conventionally, the entire word processor including the display unit and the base housing is left and right on the desk surface. In some cases, the word processor is installed in such a direction that the light is not reflected on the display screen.

However, when the entire word processor is rotated right and left, the keyboard on the base housing also tilts left and right with respect to the operator. For this reason,
There is a risk that the operability of the keyboard may be adversely affected, which hinders the input operation.

The present invention has been made in view of the above circumstances, and an installation posture of a display unit is provided so that illumination light and outdoor light are not reflected on the display screen without adversely affecting the operability of the input device. The purpose of the present invention is to provide a device for writing sentences that can adjust the text.

Another object of the present invention is to prepare a sentence that can simplify the structure of the connecting portion between the display unit and the base housing, even though the display unit is rotated back and forth and left and right. To get the equipment for.

[0011]

In order to achieve the above-mentioned object, the text-writing device according to claim 1 is erected in the rear of the input device and a base housing having an input device for information. A first hinge portion having a display unit having a flat display screen and a horizontal axis extending in the left-right direction, and connecting the display unit to the base housing so as to be rotatable in the front-rear direction with the horizontal axis as a rotation center. And a second hinge portion having a vertical axis extending in the vertical direction and connecting the upright display unit to the base housing so as to be rotatable in the horizontal direction with the vertical axis as the center of rotation. It is characterized by that.

According to a second aspect of the present invention, there is provided a base housing having an information input device on an upper surface thereof, a flat display screen, an open position for raising the display screen behind the input device, and the input device. It is premised on a text-writing device provided with a display unit rotatably in the front-back direction between a closed position covering from above and a display unit. A joint member, which is located rearward of the input device and is rotatable around a vertical axis extending in the vertical direction, is provided on the upper surface of the base housing, and the joint member is provided with a horizontal axis extending in the left-right direction. It is characterized in that the display unit is connected so as to be rotatable in the front-rear direction.

[0013]

According to the structure described in claim 1, since the display unit is connected to the base housing through the two shafts of the vertical axis and the horizontal axis which intersect each other,
When the display unit is rotated to the open position, the display unit can be rotated not only in the front-rear direction but also in the left-right direction by itself. Therefore, it is possible to adjust the installation posture of the display unit so that the display screen does not reflect illumination light or outdoor light without rotating the base housing to the left or right, and the operability of the input device is not impaired. .

According to the structure described in claim 2, since the display unit is connected to the joint member rotatable about the vertical axis via the horizontal axis, the connecting portion of the display unit to the base housing is connected. Can be integrated in one place, and the structure of the connecting portion between the base housing and the display unit can be simplified.

Rotates about the pivot shafts 33a and 33b and stands upright behind the keyboard 8. The upright angle of the display unit 3 can be freely adjusted to an angle at which the operator can easily see the display screen 17 or an angle at which the display screen 17 does not reflect the illumination light of the office or the light of the outside.

By the way, the pivot shafts 33a, 33b for rotatably supporting the display unit 3 back and forth are attached to the support walls 30a, 30b of the joint core 25. Since the joint core 25 is rotatably connected to the joint mounting portion 21 of the base housing 2 via the shaft portion 27 extending in the vertical direction, even when the display unit 3 is rotated to the open position, The display unit 3 can be rotated about the shaft 27 so as to swing in the left-right direction.
The horizontal range of rotation of the display unit 3 is determined by the gap 46 between the convex portion 43 and the enlarged portion 44 of the guide groove 42.

According to the word processor 1 having such a configuration, even when the display unit 3 is rotated to the open position, the display unit 3 can be rotated by itself so that the display unit 3 swings right and left around the shaft portion 27. The display screen 1 can be displayed by simply rotating the display unit 3 back and forth.
Even if the reflection of light on 7 cannot be eliminated, it is not necessary to rotate the base housing 2 to the left or right.

Therefore, it is possible to prevent the keyboard 8 from inclining obliquely with respect to the operator, without adversely affecting the operability of the keyboard 8, and preventing the illumination light and the outdoor light from being reflected on the display screen 17. The installation posture can be adjusted and the input operability can be maintained well.

Moreover, according to the above construction, since the joint core 25 for rotatably supporting the display unit 3 back and forth is connected rotatably to the left and right with respect to the base housing 2, the display unit with respect to the base housing 2 can be rotated. The connecting portions of 3 can be integrated in one place. Therefore, the structure of the connecting portion between the base housing 2 and the display unit 3 can be simplified, and the external appearance of the connecting portion can be maintained well. Although the keyboard is used as the input device in the above embodiment, a pen-input tablet may be used instead of the keyboard. Further, the text-creating device according to the present invention is not limited to a word processor, but can be implemented in a portable computer as well.

[0039]

According to the structure described in claim 1, even if the reflection of light on the display screen cannot be completely eliminated only by rotating the display unit back and forth, the base housing is left and right. It is not necessary to rotate the input device, and the input device does not tilt obliquely with respect to the operator. Therefore, without adversely affecting the operability of the input device,
The installation posture of the display unit can be adjusted so that the display screen does not reflect illumination light or outdoor light, and good input operability can be maintained.

According to the structure described in claim 2, although the display unit is rotatable in the front-rear direction and the left-right direction with respect to the base housing, the connecting portion between the base housing and the display unit is provided at one place. Since they are integrated, the structure of the connecting portion between the base housing and the display unit can be simplified, and the external appearance of the connecting portion can be maintained good.
