[Industrial applications]

 The present invention relates to a portable computer such as a laptop computer.

[0002]

[Prior Art]

 FIG. 5 is a side view showing the structure of a conventional portable computer, and FIG. 6 is its block diagram. In FIG. 1, reference numeral 1 denotes a main body part in which a CPU 2, a main memory 3 and the like are mounted inside, and an input / output device 4 such as a keyboard 4a and a floppy disk drive (not shown) is provided, and 5 denotes a process in the main body part This is a display unit provided with a display device 6 such as a liquid crystal display for displaying results and the like. Further, 7 is a display memory (or video RAM), and 8 is a display control circuit for controlling the display device 6.

In the above portable computer, the display unit 5 is tilted to the main body unit 1 side when being carried, and the display unit 5 is used as a cover of the portable computer. On the other hand, at the time of use, the display unit 5 is raised to expose the keyboard 4a, and at the same time, the display device 6 is positioned in front of the operator. Then, by operating the input / output device 4, the CPU 2 writes the display data such as characters and figures to the display memory 7, and the display control circuit 8 reads the display data from the display memory 7 to display the characters and figures on the display device 6. Etc. are displayed.

[Problems to be solved by the device]

 However, in the conventional portable computer, since the display device is positioned so as to face only the operator, a person located on the opposite side of the operator cannot simultaneously see the display screen. Therefore, when explaining the result processed by the portable computer to a person on the opposite side, the direction of the portable computer must be changed each time, which is inconvenient.

The present invention is intended to solve this problem, and in the case where processing is performed by a portable computer and the result is used for explanation, the operator does not have to change the orientation of the computer. It is an object of the present invention to provide a portable computer in which a person facing the user can see the same display as an operator.

[0006]

[Means for Solving the Problems]

 A portable computer in which a display device is positioned in front of an operator for use, is provided with a second display device for displaying the same contents as the display device at a position back to back with the display device. Portable computer.

[0007]

[Action]

 In the present invention, the same contents as those displayed on the display device seen by the operator are displayed on the second display device, so that the person facing the operator can see the same display as the operator at the same time. You can

[0008]

【Example】

 1 is a side view of a portable computer showing an embodiment of the present invention, FIG. 2 is a front view, FIG. 3 is a rear view, and FIG. 4 is a block diagram thereof. Here, the same symbols as those in FIGS. 5 and 6 denote the same devices. In the figure, 9 is a second display device which is provided back to back with the display device 6 on the front side of the operator, and 10 is an attachable cover that protects the second display device 9. Therefore, the display unit 5 includes the display device 6, the second display device 9 and the cover 10. Further, as shown in the block diagram of FIG. 4, the display device 6 on the front side of the operator and the second display device 9 are in a parallel relationship.

In this portable computer, the display unit 5 is tilted to the main body unit 1 side when being carried, and the display unit 5 is used as a cover of the portable computer main body unit 1. However, the second display unit 9 is further covered. Protect with 10. On the other hand, at the time of use, the display unit 5 is raised to expose the keyboard 4a, and at the same time, the display device 6 is positioned in front of the operator. Further, the cover 10 is removed to expose the second display device 9. When the input / output device 4 is operated, the CPU 2 writes the display data such as characters and figures in the display memory 7, and the display control circuit 8 reads the display data from the display memory 7 to display the display device 6 and the second device. Characters and figures are displayed on both of the display devices 9.

In this embodiment, the display device 6 and the second display device 9, the display memory 7, and the display control circuit 8 have different configurations. In addition, the display memory 7 and the display control circuit 8 may be included. Further, by allowing the display unit 5 to be set at an arbitrary angle with respect to the main body unit 1, it is possible to use the display unit 6 at the most visible angle when the operator uses it alone. Become.

[0011]

[Effect of the device]

 As described above, according to the portable computer of the present invention, even a person facing the operator can see the same display as the operator at the same time. It is possible to eliminate the inconvenience of changing the direction of the portable computer in each case as described. INDUSTRIAL APPLICABILITY The present invention is particularly effective when used while sitting face to face in a narrow room such as a reception room.
