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 unit. .

[0002]

2. Description of the Related Art A desktop or laptop type word processor includes a base unit having a keyboard and a display unit having a display screen for displaying information input through the keyboard.

The base unit has a front half portion in which a keyboard is incorporated and a rear half portion in which a printer is incorporated. The latter half of the base unit projects above the keyboard, and the display unit is connected to the boundary between the latter half and the first half. And
The display unit is freely rotatable between a closed position where the keyboard is covered from above and an open position where the display screen is erected behind the keyboard and the keyboard can be operated while watching the display screen. I am supposed to get it.

By the way, in the conventional word processor,
In order to rotatably connect the display unit to the base unit, a pair of left and right support walls are provided on the upper surface of the base unit so as to project. The support walls are provided on both left and right sides of the rear half of the base unit, and one end of the display unit is interposed between these support walls and is rotatably connected via a hinge shaft.

With this connection, the display unit can rotate about the hinge shaft between the closed position and the open position. And
When the display unit is rotated to the closed position, the upper surface of the display unit is flush with the upper surfaces of the base unit and the support wall, and the left and right side surfaces of the display unit are flush with the left and right side surfaces of the base unit and the support wall. The word processor as a whole is shaped like a flat box that is convenient to carry.

[0006]

However, according to this conventional structure, since one end of the display unit is supported between the support walls on the upper surface of the base unit, the display unit is rotated to the open position. When moved, the display unit stands up between the support walls, and the existence of the support walls becomes apparent.

Moreover, the display unit is formed in such a size that the keyboard can be completely covered when the display unit is rotated to the closed position, that is, in a plan view, it is substantially the same size as the front half of the base unit. Therefore, notches are formed on both the left and right sides of one end of the display unit so that the support wall can be inserted therein. Therefore, in the state where the display unit is rotated to the open position and is erected immediately after the keyboard, the notch is visually recognized, and the surface having the display screen of the display unit does not have a perfect rectangular shape. The existence of the connection part with the base unit becomes clear.

Therefore, in the conventional word processor, there is still room for improvement in terms of appearance and design, especially when the display unit is rotated to the open position.

The present invention has been made under these circumstances, and when the display unit is rotated to the open position, the connecting portion with the base unit is completely invisible and the appearance is improved. At the same time, it is an object of the present invention to provide a device for writing a sentence, in which a continuous part from the input device to the display unit is neatly assembled and which can have a novel design.

[0010]

Therefore, in the present invention, a box-shaped base unit having an input device for inputting information, and a display unit having a flat display screen for displaying the input information are provided. The display unit is vertically rotatable between a closed position where the input device is covered with respect to the base unit from above and an open position where the input device can be operated while viewing the display screen. In the connected writing device,

At one end of the display unit, a connecting recess is provided which is opened on the surface opposite to the display screen, and at the base unit, a supporting portion which fits into the connecting recess is provided. Between the department
The display unit is characterized in that the display unit is connected through a shaft that is horizontally placed along the left-right direction that is the center of rotation.

[0012]

With this structure, since the display unit and the base unit are connected to each other on the surface opposite to the surface having the display screen of the display unit, the display unit is rotated to the open position. Let me
In the state where the display screen is erected behind the input device, the connecting portion with the base unit is located behind the display screen.

In addition, it is not necessary to provide walls for supporting the display unit on the left and right sides of the upper surface of the base unit, and to provide notches or the like for escaping the walls on the left and right sides of the display unit. Can be formed into a perfect quadrangular shape having no dents, notches or the like at its peripheral portion.

From this, when the display unit is rotated to the open position, the display unit floats above the base unit together with the fact that the display unit often hides the connecting portion with the base unit from the front. The appearance as if it is supported in a state is obtained, and the appearance and design of the continuous portion from the input device to the display unit is improved.
