DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a perspective view showing a use state of a portable information processing apparatus according to an embodiment of the present invention. In the portable removal processing apparatus according to this embodiment, a control board and a liquid crystal display as a display screen are housed in the apparatus main body 1 and input keys 3a, 3b, 3c, 3d (input device 3 FIG. 1 is a perspective view of a place where a user actually holds and uses it with his / her hand 14 as viewed from below. In this portable information processing apparatus, the
There is a feature in that the input operation can be performed with the finger of the hand 14 holding the device main body 1 in a state where the device 14 is rotated by 0 degrees, turned around on the back surface of the device main body 1, and overlapped. This enables an input operation to be used in combination with pen input. For pen input, for example, an input panel such as a well-known transparent tablet using a pressure-sensitive element, which is set on a display screen of a liquid crystal display, is used.

As shown in FIG. 2, the input device 3 provided on the lid 2 is formed inside the lid 2 by a membrane sheet 8 constituting the input keys 3a to 3d, a reinforcing plate 10, and a cover 9 covering these. Then, a flexible cable integrally formed by the membrane sheet 8 and the cover 9 is connected to the apparatus main body 1 so as to be connected to a connector 5a provided on a control board 5 housed in the apparatus main body 1, and an input panel is used. It is used to cover and protect a certain tablet 7 or liquid crystal display 6.

When the lid 2 with the input device is used,
As shown in FIG. 3, the cover 2 is opened at 180 degrees and the apparatus body 1 is opened.
Can be used in a state where the lid 2 is opened 360 degrees and turned around the back surface of the apparatus main body 1 to be overlapped as shown in FIGS. 1 and 5. is there. In addition, when not in use, as shown in FIG. 4, the lid 2 is configured to be freely rotatable so as to cover the liquid crystal display 6 and the tablet 7 and to store them by using them as lids for protecting them. .

As shown in FIG. 1, a portable information processing apparatus which can be used in a state where the cover 2 with the input device is opened 360 degrees and turned around the back of the apparatus main body 1 has the apparatus main body 1 as shown in FIG. The input keys 3a to 3d of the input device 3 can be input with the finger of the hand 14 of the user, and the input operation can be performed in combination with the pen input. For example, as shown in FIGS. By using the lid 2 with an input device having a key arrangement, an input environment and a viewing environment can be improved and a comfortable input operation can be realized.

FIG. 6 shows a lid 2 with an input device provided simply with input keys 3a for input mode switching keys such as handwriting input with a pen and Roman character input when used as a word processor.

FIG. 7 shows the lid 2 with an input device further provided with a screen / cursor scroll key, a kanji conversion key, and an enter / execute key as input keys 3b to 3d. If data is only displayed and viewed without inputting characters with a pen, processing can be performed by providing a screen / cursor scroll key 3b and a confirm / execute key 3d.

FIG. 8 shows the input keys 3a to 3d shown in FIG.
This is an embodiment in which input keys 3e to 3h for instructing the same function are provided on the opposite side, so that the input operation can be similarly performed even when the apparatus main body 1 is held by the right hand. In another embodiment, all the input keys 3a
By providing ~ 3h as input keys for instructing different functions, it is also possible to carry out an input operation by holding with both hands when a character is not input.

As shown in FIG. 9, an input key 11 may be provided on the back surface or side surface of the apparatus main body 1 irrespective of the lid 2. FIG. 10 is a cross-sectional view taken along the line II in FIG. 9. A soft changeover switch 5b for generating an ON / OFF electric signal is provided on the control board 5, and a switch button made of a plastic or the like is formed on the soft changeover switch 5b. 11 is mounted on the lower case 1b so as to face the soft changeover switch 5b, and the switch button 11 is deformed by pressing the switch button 11 so that the soft changeover switch 5b on the control board 5 is depressed.
Is operated as a substitute for an input mode switching key or the like.

The input keys such as the input mode switching key 3a and the screen / cursor scroll key 3b exemplified in these descriptions may be input keys for optimal operation according to the specifications and use of the information processing apparatus. 3 to 3 h are input keys required according to the specifications of the information processing device developed by the maker, and there is no need to stick to the input mode switching key and the screen / cursor scroll key exemplified in the description. For example, a registration / end key for registering a created document may be provided. Also, a large number of deformation patterns can be considered for the number and arrangement of keys. Note that inputs from these keys are input to a control circuit (not shown), and processing is executed according to a preset program.

Next, as shown in FIG. 3, a case where the present invention is applied to a portable information processing apparatus in which standard input keys are fully arranged in the input apparatus 3 will be described. Since the device main body 1 of the portable information processing device is basically made for the purpose of miniaturization and weight reduction, when the input keys of the input device 3 are fully arranged, the key size and Because the key pitch is small and it is difficult to perform input operations with your fingertips,
It is impossible to perform a key input operation in a 360-degree opened rotation state or in a state where it cannot be visually confirmed. Therefore, the device body 1
In order to perform an input operation with a finger having a hand, for example, the function assignment of the key pattern is changed so that any one of the four input keys can be used as an input mode switching key or the like, and a pseudo pattern as shown in FIG. Change the size of the input key. These are input keys 3a to 3d indicated by solid lines in the figure. The input keys 3a and 3b are places where standard input keys are not arranged. In such a case, this area is secured and displayed from the beginning so that the input operation can be performed when changing the key pattern. . Thus, the user can perform an input operation by storing the approximate position. At this time, the input keys that are not used are switched so that they do not respond when pressed (the input keys indicated by broken lines in the figure correspond to the input keys. In practice, the characters of the standard input keys are described. It is drawn with a broken line for easy understanding). For the key pattern switching, a switching touch button 7b is provided on the tablet 7, and the switching is performed on a program set in a control circuit (not shown) by ON / OFF of the touch button 7b.

As another embodiment, a key pattern switching key 12 is provided on the back side of the surface of the cover 2 with the input device shown in FIG. 4 where the input keys are provided (the external surface of the cover 2 when not in use). When the cover 2 with the input device is opened 360 degrees and turned into the back side of the device main body 1, the ON / OFF operation is performed by touching the convex portion 13 on the back surface of the device main body 1 as shown in FIG. Then, a key pattern switching instruction can be generated. Conversely, a convex portion is provided on the lid 2 with the input device, and when the lid 2 is opened 360 degrees and wrapped around the back side of the device main body 1, the convex portion comes into contact with the rear surface of the device main body 1. It is also possible to provide a key pattern changeover switch having a structure as shown in FIGS. 9 and 10 and operate the key pattern changeover switch by the projection.

[0024]

As described above, according to the present invention, the input operation can be performed with the finger of the hand holding the apparatus main body, and the input operation can be performed in combination with the pen input using the input panel superimposed on the liquid crystal display. Therefore, it is possible to configure a portable information processing device that improves the input environment and the viewing environment and realizes a comfortable input operation.
