Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing device,
In particular, the present invention relates to a portable information processing device including a display device such as a word processor and a mini computer and a keyboard.

[0002]

2. Description of the Related Art In recent years, with the advance of technology, miniaturization of such electronic devices has progressed, and book-type products for information processing devices have appeared. By the way, the factors that determine the external dimensions of these products are mainly the flat display device and the keyboard, and since these two devices are configured to be closed face to face with each other,
It is called a book type. By the way, if the key arrangement and pitch of the keyboard are small, it is difficult to use, and if the display is small, it is difficult to see. However, even if the display is considerably thin, it does not cause any inconvenience in operation. However, if the operation stroke of the key is shortened, the keyboard loses the operational feeling, and thus it is difficult to reduce the thickness.

Therefore, for example, a configuration is conceivable in which, when the display is tilted on the keyboard to be closed, each key is forcibly pressed and held by a key stroke.

[0004]

However, when the information processing apparatus is made thin as described above, the strength of the display apparatus itself is insufficient because the display apparatus itself is thin, and when the display is overlaid on the keyboard. In addition, the central part of the display is pushed up by the key top in reverse, the display warps, or
The pressing of the key tops may put stress on the display and cause a malfunction. If the spring of the keystroke is weakened in order to solve this, the feeling of operation is impaired.

It is an object of the present invention to pay attention to the above-mentioned problems, and in order to solve the problems, it is possible to realize a thin type in a folded state without both the display and the keyboard being overpowered. It is to provide a processing device.

[0006]

To achieve the above object, the present invention provides a keyboard in which a plurality of keys are arranged, and the keyboard is rotatably supported on the side of the keyboard. In a foldable information processing device having a display that can be stored at a position, a push-down member that engages at a position that is not related to the operation of the plurality of keys and that can press down the key tops of the plurality of keys at the same time, It is characterized in that it is provided with a pressing means arranged on the display side for pressing the pressing member by the storing operation and a locking means for holding the pressing member in the pressing position.

[0007]

According to the present invention, when the display is rotated to the facing position of the keyboard to be stored, the pressing means on the display side presses a plurality of key tops through the pressing members according to the storing operation by the rotation. The keys are pushed down all at once, and the locked state is held by the locking means without the display surface of the display touching the key tops in the pushed state, so an unreasonable pushing force is generated between the keyboard and the display. In addition, the keyboard can be formed thin to at least correspond to the stroke of the key, and the overall size can be reduced.

[0008]

Embodiments of the present invention will be described in detail and specifically below with reference to the drawings.

FIG. 1 shows an embodiment of the present invention. In (A), 1 is a display (device), 2 is a keyboard housing, 3 is a key, 4 is a hole for pushing the key 3 downward as described later, and 5 is provided on both sides of the display 1. Depressed operation protrusion of the key 3, 6 is a locking member, 7 is a locking release lever, 8 is a locking hole of the locking member 6, and 9 is a display rotating shaft. here,
The display 1 is brought into a closed storage state by rotating the display rotating shaft 9 in the direction of the arrow A using the display rotating shaft 9 as a fulcrum. At this time, the key-pressing operation projection 5 is pressed into the key-pressing hole 4, and Locking member 6
Are engaged with the locking holes 8, respectively.

Reference numeral 10 shown in FIG. 1B is a key pressing plate. The key pushing plate 10 has a key hole 11 at a position corresponding to each key 3, which engages with the skirt of the inclined portion of each key 3, as shown in FIG. Engaged and held. Further in FIG. 2, 1
Reference numeral 2 is a reinforcing rib for increasing the strength against bending, and 13 is a return spring for the key 3.

In the information processing apparatus having the above-described structure, when the keys are operated, as shown in FIG.
No. 0 is supported in a state of keeping contact with the inclined portion of the key 3 that is not operated, but there is no hindrance to the operation of the key 3 that is pressed as indicated by the arrow, and operation is performed with the conventional feeling maintained. I know that is possible. Also, when carrying the device, the display 1 can be closed in a state of being stacked on the keyboard (keyboard housing) 2 by rotating the display 1 around the rotating shaft 9 shown in FIG. ..

FIG. 4 shows the state of being housed in this way. Further, FIG. 5 is a cross-sectional view showing such a closed storage state, in which the key-pressing projections 5 are formed with the key-pressing holes 4 provided at the left and right ends of the keyboard housing 2. Since it is introduced into the housing 2 through the key-pressing plate 10 as shown in FIG.
Is kept depressed, and all the keys 3 are pushed down by the key pushing plate 10 against the spring force of the spring 13. That is, in this state, the height of the top is higher than that of the key 3 shown in FIG.
The stroke is kept low by about 3.5 mm, and in this state, it is set so that a margin of about 0.5 mm is still maintained between the display surface 1A of the display 1 and the key top 3A. The display surface 1A is neither stressed nor damaged.

Further, since the display 1 is held in the closed state by the engagement of the locking member 6 and the locking hole 8, the details will be omitted when the display 1 is started up and put into a use state. , The locked state is released by operating the lock release lever 7 attached via a spring mechanism (not shown), and the display rotation shaft 9 is rotated in the direction of arrow B as a fulcrum, as shown in FIG. The state shown in A) can be restored. Furthermore, as a measure to prevent the key 3 from being inadvertently pressed by closing the display 1 while the power is on, for example, an open / close sensor is mounted and the key 3 is pressed by the key pressing plate 10. It is desirable to configure so that the key input is invalidated or the power is turned “off” before being pressed by.

(Other Embodiments) In the embodiment described above,
As a means for pushing the key 3 when the display 1 is closed, the key pushing plate 1 that engages with the skirt of the inclined portion of the key 3
0 is used to press the entire key 3, and two key pressing protrusions 5 are provided on each of the left and right sides of the display 1 so that a sufficient pressure can be obtained when the key is pressed. The number of such key-pressing projections 5 is not limited to this, and as shown in FIG. 6, there is one at each of the left and right sides of the display 1, and even if there are a total of two, the same pressing function is achieved. In addition, a simple design can be obtained by reducing the number of key-pressing projections 5.

Further, instead of pushing the entire key 3 by the key pushing plate 10, the rows E and F at the front and rear ends of the row of the key 3 shown in FIG. 6 are displayed on the casing of the display 1 as shown in FIG. It is also possible that the upper and lower ends of the body are lightly pushed in, and the remaining keys 3 are pushed in by similar means by a key pushing plate 20 smaller than that used in the above-mentioned embodiment. In this case, the reaction force applied to the display 1 from the keys 3 in the E row and the F row acts as a force to bend the display 1 itself upward because the keys 3 in these rows are located at the ends. There is nothing to do.

[0016]

As described above, according to the present invention, a keyboard in which a plurality of keys are arranged and the keyboard is rotatably supported on the keyboard side, and the keyboard is housed in the facing position of the keyboard by the rotation. In a foldable information processing device having a display capable of, a push-down member that engages at a position that is not related to the operation of the plurality of keys and is capable of simultaneously pushing down the key tops of the plurality of keys, and the display side. Since the display is provided with the pressing means for pressing the pressing member by the storing operation and the locking means for holding the pressing member in the pressed position, the display can be displayed without applying a force to deform the display. The entire keytop can be pushed down in conjunction with its operation when the By an amount corresponding to the keyboard, it is possible to realize a turn entire thickness. Further, since the key tops do not come into contact with the display surface of the display, there is no possibility of being damaged by each other, and the feeling of operating the keys can be maintained as in the conventional case.
