Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable computer such as a portable personal computer or a word processor provided with a pointing device.

[0002]

2. Description of the Related Art FIG. 6 is a perspective view showing a conventional portable personal computer. In FIG. 6, 51 is a personal computer main body, 52 is a floppy disk device provided in the personal computer main body 51, 53 is a keyboard provided on the upper surface of the personal computer main body 51, 54 is a pointing device, and 56 is arranged in the vicinity of the pointing device 54. A pointing device set switch 57, a pointing device cancel switch 57, and a display 58.

In this portable personal computer,
When performing graphic processing, etc., a floppy disk storing software for graphic processing is set in the floppy disk device 52, and then this software for graphic processing is activated to perform graphic processing on the display 58 to perform graphic or table display. Will be created and edited.

In this case, the pointing device 54, the pointing device set switch 56, the pointing device cancel switch 57, and the keyboard 53 are operated to draw a figure or a table on the display 58. The operation of the pointing device 54 is performed. In this case, the pointing device set switch 56 or the pointing device cancel switch is usually operated by the ring finger or middle finger of the same right hand while operating the spherical surface of the pointing device 54 with the right hand to move the cursor on the display 58 to a desired position. Operate 57.

[0005]

However, when the pointing device 54 is operated by the left hand and the pointing device set switch 56 or the pointing device cancel switch 57 is operated by the right hand, the posture of the operator becomes unreasonable, It had the drawback of being difficult to operate.

The present invention has been made in order to solve the above problems, and makes it possible to operate the pointing device in a natural posture, thereby facilitating the operation of the pointing device and operability. It is an object of the present invention to provide a portable computer with improved performance.

[0007]

A portable computer according to the present invention is a portable computer comprising a pointing device and an input switch for inputting data in response to an operation of the pointing device, wherein the input switch is It is characterized in that at least two of them are provided, and they are respectively attached to different places.

[0008]

According to the present invention, since two sets of input switches are provided at different places, the input switch can be selected according to the operation situation. For this reason, since it is possible to operate with both hands in a natural posture, operability is improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a portable computer of this embodiment, 1 is a personal computer main body, 2 is
Is a floppy disk device provided in the personal computer main body 1, 3 is a keyboard provided in front of the upper surface of the personal computer main body 1, 4 is a pointing device, 5 is a pointing device set switch arranged in the vicinity of the pointing device 4, Similarly, 6 is a pointing device cancel switch.

Reference numeral 7 is a second pointing device set switch disposed on the upper left corner of the upper surface of the personal computer main body 1, and reference numeral 8 is a second pointing device cancel switch. 9 is a display.

2 is an enlarged perspective view of the pointing device set switch 5 and the pointing device cancel switch 6 in FIG. 1, and FIG. 3 is a sectional view showing the internal structure of the pointing device set switch 5 and the pointing device cancel switch 6, The pointing device set switch 5 and the pointing device cancel switch 6 have the same internal structure.

In FIG. 3, reference numerals 5a and 5b denote tact switches for setting the data input by the pointing device 4, and one end of the cact switch 5c is fixed on the personal computer main body 1 and the other end is on the back surface of the switch operating plate 5e. The fixed coil spring 5d is also a coil spring whose one end is fixed on the personal computer main body 1 and the other end is fixed to the back surface of the switch operation plate 5e.

FIG. 4 is a wiring diagram showing a connection relationship between the pointing device set switch 5 and the second pointing device set switch 7, and FIG. 5 is a connection between the pointing device cancel switch 6 and the second pointing device cancel switch 8. It is a wiring diagram which shows a relationship.

Next, the operation will be described. In this portable computer, the pointing device 4 is operated with the right hand to move the cursor on the display 9 displaying various data and processing information, and various data and processing information displayed on the display 9 are displayed. By selecting the desired information from the above with the cursor and operating the pointing device set switch 5, various data and processing information specified by the pointing device 4 are selected, and input / output and processing of the selected data are performed. To execute.

In this case, while the right hand is operating the pointing device 4, the pointing device set switch 5, and the pointing device cancel switch 6, the key operation of the keyboard 3 is performed with the left hand.

At this time, while operating the pointing device 4, the pointing device set switch 5
Or pointing device cancel switch 6
When it becomes necessary to operate, the operator operates the pointing device 4 with the right hand and operates the second pointing device set switch 7 and the second pointing device cancel switch 8 with the left hand.

Since the second pointing device set switch 7 is connected in parallel to the pointing device set switch 5 as shown in FIG. 4, by operating the second pointing device set switch 7, the pointing device set switch 5 is operated. Since the operator operates the pointing device 4 with the right hand and the second pointing device set switch 7 with the left hand, the operator can operate the pointing device 4 in a natural posture. Further, since the operation with the right hand is performed only by the pointing device 4, the operation of the pointing device 4 is performed intensively by the right hand, which facilitates the operation of the pointing device 4. Similarly, with respect to the pointing device cancel switch 6, the second pointing device cancel switch 8 can be used with the left hand, so that the pointing device 4 can be operated in a natural posture.

[0018]

As described above, according to the present invention, the two sets of pointing device input switches having the same function are provided in the portable computer, so that the operator can place the pointing device input switches on the side that is easy to use depending on the situation. Since the pointing device input switch can be used, the pointing device can be operated accurately, and a portable computer with improved operability can be obtained.
