Description

  The present invention relates to an input device in a notebook personal computer.

  In recent years, an increasing number of people use notebook personal computers (hereinafter referred to as notebook PCs) outdoors, and notebook PCs are rapidly spreading. In addition, a notebook PC having an input device in which an information input device is configured by a combination of a liquid crystal display panel and a touch panel instead of a general keyboard and mouse pad has been proposed.

  A conventional notebook PC will be described below.

  FIG. 3 shows a conventional notebook PC.

  In FIG. 3, 1 is a display unit comprising a liquid crystal display panel, a liquid crystal display circuit, and the like, 2 is a notebook PC body, and the key arrangement is electrically arranged on the surface of the notebook PC body 2 by a combination of a liquid crystal display panel and a touch panel. An input operation unit 3 that can be displayed and input is arranged.

  The operation of the conventional notebook PC configured as described above will be described below.

First, a basic key layout is displayed on the input operation unit 3 by turning on the power of the notebook PC. It is detected that a key displayed at each position is pressed from the coordinate position where the touch panel of the input operation unit 3 is pressed, and a key code corresponding to the code of each key is generated. As for the key layout, it is possible to freely change the key layout by selecting a desired key layout.

  However, in the above-described conventional configuration, the input operation unit 3 is configured only by a combination of a liquid crystal display panel and a touch panel, and the mouse button for click operation used in combination with the mouse pad operation and the mouse pad is removed. Therefore, only a keyboard input operation is possible, and there is a problem that an input operation using a mouse pad cannot be performed.

  Furthermore, when a conventional input device performs key input, the key operation displayed on the liquid crystal display panel is operated on the touch panel, so that the input operation unit is completely flat, and when operated, a blind touch operation cannot be performed. Had problems.

  SUMMARY OF THE INVENTION The present invention solves the above-described conventional problems, and an object thereof is to provide a notebook PC that enables both keyboard operation and mouse pad operation, has a mouse button, and allows a blind touch input operation. To do.

The invention described in claim 1 of the present invention
An input device for a notebook personal computer,
By configuring the liquid crystal display panel and the touch panel in combination, an input operation unit that displays a keyboard on the liquid crystal display panel and enables operation as a mouse pad by switching;
A mouse button for a click operation used when operating the input operation unit with a mouse pad;
A changeover switch for switching the input operation unit to mouse pad operation and keyboard input operation;
The input device of the notebook personal computer is characterized in that it has the function of improving the operability of the mouse pad operation because the entire input operation unit can be changed to the mouse pad operation.

The invention described in claim 2
2. The input device for a notebook personal computer according to claim 1, wherein an outer frame is provided around the input operation unit, and a blind touch is made possible by providing an outer frame around the input operation unit, and mistouch is reduced. Have the effect of

  As described above, according to the present invention, the input operation unit can be operated by both functions of the keyboard and the mouse pad, and the entire input operation unit can be changed to the mouse pad, so that the operability of the mouse pad operation is improved. Furthermore, the outstanding effect which enables a blind touch is acquired by providing an outer frame around a touch panel.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

(Embodiment 1)
FIG. 1 is an overview of a notebook PC according to the present invention.

  In FIG. 1, 11 is a notebook PC body, 12 is a display unit comprising a liquid crystal display panel, a liquid crystal display circuit, and the like, 13 is a changeover switch for switching the input operation unit to mouse pad operation and keyboard input operation, and 14 is a liquid crystal display. An input operation unit that electrically displays a keyboard arrangement on the liquid crystal display panel by combining a display panel and a touch panel, and enables operation as a mouse pad by switching the changeover switch 13, and 15 is a mouse for the input operation unit 14 This is a mouse button for click operation used for pad operation.

  2A and 2B are detailed views of the input device of the notebook PC of the present invention. FIG. 2A is a plan view when a keyboard input operation is performed, and FIG.

  2 (a) and 2 (b), reference numerals 13, 14, and 15 are the same as those in FIG. FIG. 2C is a cross-sectional view of an input device in which a liquid crystal display panel and a touch panel are combined, and 16 is an outer frame provided around the input operation unit 14.

  The operation of the notebook PC configured as described above will be described with reference to FIGS.

  First, FIG. 2A shows a state where the keyboard layout is output to the input operation unit 14. In this case, the input operation of the mouse button 15 disposed adjacent to the input operation unit 14 is invalidated to reduce erroneous input due to mistouch.

  Next, FIG.2 (b) is the state which made the input device part 14 input operation of a mouse pad. In this case, unlike the keyboard layout, the operation of the mouse button 15 is enabled. 2A and 2B are switched using the changeover switch 13 when switching to the keyboard operation and the mouse pad operation.

  In FIG. 2C, the outer frame 16 is provided to facilitate blind touch of keyboard input and mouse pad input, and to reduce mistouch.

  As described above, according to the present embodiment, the input operation unit 14 is configured by a combination of a liquid crystal display panel and a touch panel, and the changeover switch 13 is provided for switching the input device between a keyboard input operation and a mouse pad input operation. Thus, both keyboard input and mouse pad input can be performed. When the mouse pad is input, the entire input operation unit 14 can be used as an operation area of the mouse pad, and mouse pad input is facilitated by detailed operation by mouse pad operation. Improved operability.

  Furthermore, since the mouse button is disabled during keyboard input operation, erroneous operation of the mouse button during keyboard operation can be prevented.

  In addition, by providing an outer frame around the input operation unit, it is possible to facilitate blind touch of keyboard input and particularly mouse pad input, and reduce mistouch.

  In the above description, the outer frame 16 of the input operation unit 14 is expressed as “frame”. However, a step is provided at the boundary between the input operation unit 14 and the notebook PC main body 11, and the input operation unit 14 is formed in a concave shape. In this way, the same effect can be obtained (FIG. 2 (c ′)).

  Further, if an outer frame surrounding the input operation unit 14 or a plate material obtained by cutting out the input operation unit in a window shape is configured to be detachable, the user's preference can be dealt with.

  The notebook PC according to the present invention has an effect that the operability of the mouse pad operation is improved because both the keyboard and mouse pad functions can be operated on the input operation unit, and the entire input operation unit can be changed to the mouse pad. It is useful as an input device for notebook PCs.
