Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable information processing device.

In recent years, information processing devices such as personal computers have become smaller and more dense, and many portable information processing devices such as notebook computers have been proposed. Under such circumstances, file devices, control devices, etc. are becoming smaller and higher in density, but since the keyboard device that is the input / output unit requires a certain size, it is a constraint for downsizing the entire device. ing.

[0003]

2. Description of the Related Art Generally, in a portable information processing device such as a notebook computer, a display section using a liquid crystal panel or the like and a main body section having a keyboard section on the surface section are foldably connected by an appropriate hinge. In order to further reduce the size of the portable information processing device configured as described above, the numeric keypad (numeric input key) is removed from the keyboard unit or the key top shape is reduced.

[0004]

However, as described above, when the numeric keypad is removed from the keyboard portion or the key top shape is reduced to reduce the size of the keyboard surface, the operability of the apparatus is extremely deteriorated. It had a drawback that it would end up.

The present invention has been made to solve the above drawbacks, and an object of the present invention is to provide a portable information processing device which can be downsized without deteriorating the operability.

[0006]

According to the present invention, the above object is to mount a display section 2 on a main body section having a keyboard section 1 in a foldable manner as shown in FIG. 1 corresponding to an embodiment. comprising the portable information processing apparatus, said keyboard
The display part 1 is orthogonal to the rotation center axis direction of the display part 2.
Formed so that it can be folded in half around the axis, and in the expanded state
This is achieved by providing a portable information processing device characterized in that the display unit can slide in the left-right direction .

In this case, the sliding path of the keyboard section 1
The can also this to place the locking member 3 for regulating the sliding end position of the keyboard portion 1, further, formed by a push button switch for advancing and retracting the locking member 3 on the sliding path of the keyboard section 1, the It is also possible to connect and disconnect the main power source at the sliding end position of the keyboard unit 1.

[0008]

Based on the above construction, the keyboard portion 1 in the portable information processing apparatus according to the present invention is constructed so as to be foldable in half, so that the space can be saved when it is carried. Further, since the keyboard portion 1 can be unfolded at the time of use and a sufficient space for arranging the key tops is secured, it is not necessary to omit the ten-key pad or reduce the size of the key top shape. Operability is not deteriorated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

In the embodiment shown in FIGS. 1 to 5,
The portable information processing device is configured to include a display unit 2 formed of a liquid crystal panel or the like and a control unit 5 connected to the display unit 2 via a back surface member 4, and the display unit 2 and the control unit. By rotatably pivoting 5 on the back member 4, it is possible to arbitrarily change the angle between them.

On the other hand, the keyboard portion 1 has a shaft 7 whose central portion in the longitudinal direction is orthogonal to the direction of the rotation axis 6 of the display portion 2 and the control portion 5.
It is formed so as to be foldable around, and a guide ridge 8 protruding from one side edge thereof is slidably fitted in a guide groove 9 of the back member 4.

The interval between the rotary shafts 6 of the back member 4 is set so as not to interfere with the key tops 10 of the keyboard portion 1 when the keyboard portion 1 is folded and housed. Wiring between the display unit 2, the control unit 5, and the keyboard unit 1 is performed by passing a flexible printed board 12 or a cable through a hollow portion 11 formed in the back member 4, but otherwise. In addition, it is possible to connect using radio waves or light.

In the portable information processing apparatus according to the present invention having the above-mentioned structure, when not in use, the keyboard unit 1 is folded around the axis 7 and the keyboard unit 1 is connected to the display unit 2 and It is in a state of being sandwiched by the control unit 5. The display unit 2 and the control unit 5 are locked by a locking member (not shown), and are locked so that the display unit 2 cannot be opened when being carried.

To shift from this state to the use state,
First, as shown in FIG. 2, the display unit 2 and the control unit 5 are rotated about the rotation shaft 6 of the back member 4 and are developed so as to be substantially flush with each other (see FIG. 4). Next, the keyboard unit 1 is rotated about the axis 7, that is, in the direction of the arrow in FIG. 4 to develop the surface of the key top 10 into a flat surface, and then the control unit 5 is returned to the rear surface position of the keyboard unit 1.

Here, as shown in FIG. 5, the cover wall 13 erected at the free end of the control section 5 is slidably fitted to the slide protrusion 14 on the front side wall surface of the keyboard section 1, as shown in FIG. A slide groove 15 is formed, and the control unit 5 is returned to the original position to engage them, and then the keyboard 1 is slid along the slide groove 15.

On the other hand, a lock member 3 is arranged at a portion that interferes with the sliding path of the keyboard portion 1, and the keyboard portion 1 is slid to a position where the keyboard portion 1 is equally distributed to the center of the display portion 2. When it moves, the sliding operation is locked by the lock member 3, and the keyboard portion 1 is held at that position. This state is the use state shown in FIG.

Further, foldable legs 16 are provided at both ends of the keyboard portion 1, and the keyboard portion 1 is provided.
When you use, you will be standing down.

As the lock member 3, a general mechanical lock mechanism can be used, but in addition to this, a push button switch for moving the operation button 17 forward and backward can be used. In this case, the power can be turned on only when the keyboard unit 1 is expanded at the proper position.

In this way, there is shown a modified example in which the lock member 3 is formed by a push button switch, and the switch is the front side wall surface of the keyboard portion 1 when the keyboard portion 1 is used. The cover wall 13 is arranged at a position that matches both end positions of the cover wall 13.

However, in this example, when the switch is not in use, the operation button 17 is pressed against the cover wall 13 of the control unit 5 to bring it into a disconnected state, and when the keyboard unit 1 is slid sideways during use, the cover is covered. The pressure applied by the wall 13 is released and the wall portion 13 is projected to the front surface side to mechanically lock the keyboard portion 1 and make a transition to a power-on state.

In the above embodiment, the case where the keyboard unit 1 is housed so as to be sandwiched between the display unit 2 and the control unit 5 is shown, but in addition to this, it is shown in FIG. As described above, it is also possible to store the control unit 5 by sandwiching the control unit 5 with the keyboard unit 1. In this case, as shown in FIG. 9, the lower keyboard unit 1 is rotated downward. By unfolding and sliding to the side, a transition to the use state is made.

[0022]

As is apparent from the above description, according to the present invention, since the keyboard portion can be folded when not in use, portability can be improved,
In addition, since the required area is secured during use, it is possible to arrange keys on the same level as the desktop type, improving usability.
