It is rotatable about its center, and it is rotatable about the display panel part that can be stopped from the folded state overlaid on the top surface of the device body to an appropriate angle and the hinge shaft at the front end of the device body. There is a keyboard section that can be in a state of folding the display panel section in the folded state on the upper surface side of the device body and a state in which it is inverted and rotated to the front side of the device body, and a front end portion of the device body. It is configured to be rotatable about a hinge shaft, and to be provided with a handle portion that serves as a tilt leg at the time of use at a position around the lower portion on the front end side of the device body.

(Operation) If it is a portable electronic device having such a configuration,
Not only the display panel section, but also the keyboard section can be rotated, so when not in use, the display panel section,
It is possible to store the keyboard part etc. together.

Therefore, it becomes possible to further reduce the area occupied by the device on the desk or the like when not in use.

(Embodiment) FIG. 1 is a perspective view showing a stored state of a portable electronic device according to an embodiment of the present invention. Further, FIG. 2 is a side view showing a usage state in which the same device is developed.

A keyboard unit 9 having a hinge shaft 6 for rotatably mounting a display panel unit 8 having a display surface 4 and a keyboard 5 at the front end of a thin box-shaped device body 1 having various processing circuits, power supplies and the like built-in. A second hinge shaft 7 is provided for rotatably attaching the handle and the handle 2. As described above, in this embodiment, the handle portion 2 and the keyboard portion 9 are attached by the common hinge shaft 7 provided at the front end portion of the device body 1 and substantially at the center in the height direction. Slightly above,
A hinge shaft 6 of a display panel unit 8 is provided near the upper end of the front end of the device body 1.

A floppy disk drive 3 is attached to the front end surface of the device body 1 as an external memory, and a groove portion 10 is formed on the upper portion of the hinge shaft 7 of the keyboard portion 9 for facilitating gripping of the handle portion 2. .

Then, with the hinge shaft 7 as the center of rotation, the keyboard portion 9 is substantially half-opened in front of the main body of the device, and the keyboard 5 is rotated in the reverse direction to expand upward, and the display surface 4 is moved forward about the hinge shaft 6. Raise the display panel section 8 toward
It can be in use.

At this time, by rotating the handle portion 2 to below the bottom surface of the main body 1 and engaging with the taper portion 11 formed on the side surface of the main body 1, the device main body 1 and the keyboard portion 9 can be provided with an appropriate slope that is easy to use. It is made possible.

Further, the display panel portion 8, the keyboard portion 9 and the like are turned down on the upper surface of the device body 1 to be closed or put in a portable state. A one-touch lock mechanism 12 is provided at one end of the keyboard portion 9 and can be locked with the main body 1 when the keyboard portion 9 is closed.

In this way, compared to conventional electronic devices of this kind,
It is possible to further reduce the equipment installation area when not in use.

FIG. 8 is a side view comparing the sizes of the electronic device shown as the conventional example and the electronic device of this embodiment when stored. The difference in depth between the conventional device (b) and the device (a) according to the present invention can be clearly discriminated. Of course, the width of the device is almost the same unless the size of the display surface or the width of the keyboard is changed, and therefore the difference in the depth dimension shown in this figure directly becomes the difference in the bottom area.

In this way, by folding the keyboard part, a three-layer structure of the main body, the display panel part, and the keyboard part is formed, and the installation space at the time of storage can be reduced.

In addition, since the size of the data display surface is limited due to the portable type, this type of device is inferior in viewability to a CRT device having a wider screen. For this reason, such a large-screen display device may be connected and used instead of the display panel unit attached to the device.

However, if the electronic device shown in the conventional example is CR
If a CRT device is placed behind the main body when connecting a T device, etc., the display panel of the main body and the CRT screen will overlap.

On the other hand, when the CRT device or the like is placed close to either the left or right side of the main body, the movements of the line of sight looking at the keyboard and the line of sight looking at the display panel become large in the left / right and up / down directions, which makes it easy to get tired.

FIG. 9 shows an explanatory view when a CRT device or the like is connected and used instead of the display panel section. (B) is a case where the conventional device as described above is used. In order to use the keyboard, the display panel section must be set up, so CR
The screen of the T device becomes difficult to see.

In comparison with this, in the electronic device of the present embodiment as shown in (a), only the handle part and the keyboard part are opened, and the display panel part can be used even when the display panel part is turned down on the upper surface of the device body. Even if a large CRT device or the like is connected and used, there is no problem in viewing the screen, and the amount of movement of the line of sight is the same as the display panel section of the device, making it easy to see.

Furthermore, as shown in FIG. 10, when carrying,
In the case of the device as shown in the conventional example, since the fulcrum of the handle is located at the lower rear part of the main body, there is a problem that the main body is tilted as shown in FIG.

On the other hand, in the electronic device of this embodiment, since the hinge shaft for the handle part, which is common to the keyboard part, is provided substantially at the center in the height direction of the front end part of the main body, even if it is lifted, as shown in FIG. As described above, there is an advantage that it is easy to carry without tilting.

The detailed configuration of the hinge mechanism of the portable electronic device of this embodiment will be described below.
