Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal computer.

[0002]

2. Description of the Related Art FIG. 6A shows a personal computer.
There are two types, a desktop type shown in Fig. 6 and a notebook type shown in Fig. 6B. In FIG. 6A, the desktop personal computer includes a keyboard unit 20 and a mouse 21, which are input units, an arithmetic processing unit 22,
The display unit 23 is independently configured, and the keyboard unit 20 or the mouse 21 and the arithmetic processing unit 22 and the arithmetic processing unit 22 and the display unit 23 are connected to each other via a cable (not shown). In FIG. 6B, the notebook personal computer is a computer main body 24.
A keyboard section 24 disposed on the upper surface of the computer, an arithmetic processing section (not shown) built in the computer main body 24, and a display section 2 rotatably provided on the computer main body 24.
6 is comprised. In general, a desktop personal computer is a cathode ray tube as shown in FIG. 6 (a), and a notebook personal computer is as shown in FIG. 6 (b).
The display unit 26 is composed of a liquid crystal display unit.

[0003]

However, according to the above conventional configuration, the size of the personal computer largely depends on the size of the display units 23 and 26 used, and therefore the display units 23 and 26 are the same as those of the personal computer. The miniaturization is hindered, and the large display screen leads to the large personal computer.

It is therefore an object of the present invention to provide a personal computer which is small and lightweight and which can be used for a large display screen.

[0005]

A personal computer of the present invention for achieving the above object comprises an input section for inputting data, and an arithmetic processing section for performing an arithmetic operation based on the data input from the input section. In a personal computer including a display unit for displaying the calculation result of the calculation processing unit, the display unit is a front type projector including a projector main body and a screen.

[0006]

Since the display unit is composed of the front type projector, a projector unit that is much smaller than the cathode ray tube or the liquid crystal display unit may be provided on the computer body side, and the screen size displayed on the screen can be reduced. It can be changed arbitrarily.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment of the present invention. FIG. 1 is an external perspective view of a personal computer, and FIG. 2 is a block configuration diagram thereof. 1 and 2, a keyboard unit 3 as an input unit is arranged on the upper surface of the cabinet 2 of the computer main body 1, and an arithmetic processing unit 4 is housed in the cabinet 2. Data is input from the keyboard unit 3, and the arithmetic processing unit 4 performs arithmetic operations based on the input data.
A storage means 5 such as a CD-ROM or a floppy disk is detachably configured in the computer main body 1,
The data stored in the storage means 5 is read out as necessary, and the data is written in the storage means 5.

Further, a projector main body 6 is provided on the side of the cabinet 2 of the computer main body 1 so as to project data such as a calculation result of the calculation processing section 4 to the projector main body 6. The projector body 6 projects the data such as the calculation result on the screen 7. The screen 7 is arranged at a position slightly separated from the computer body 1. That is, the display unit is configured by the front type projector 8 including the projector body 6 and the screen 7.

In the above structure, only the projector main body 6 is attached to the computer main body 1 side, and the projector main body 6 is much smaller and lighter than the liquid crystal display section, so that the personal computer itself is very small and lightweight. To do. Further, since the display screen size of the screen 7 can be freely changed, the display screen can be enlarged without enlarging the display unit.

A second embodiment of the present invention is shown in FIGS. FIG. 3 is an external perspective view of the personal computer, and FIG. 4 is a block configuration diagram thereof. 3 and 4, in the second embodiment, as compared with the first embodiment, a liquid crystal display unit 9 is rotatably provided at the upper end of the cabinet 2 of the computer main body 1, and the display unit has a liquid crystal display. Section 9 and front type projector 8
It consists of and. The difference is that the data from the arithmetic processing unit 4 is configured to be selectively output to the liquid crystal display unit 9 and the projector body 8 via the selection switch SW. Since other configurations are the same as those of the first embodiment, the same reference numerals are given to the drawings and the description thereof will be omitted. still,
The liquid crystal display unit 9 may be replaced by a cathode ray tube.

In the above structure, when the liquid crystal display 9 side is selected by the selection switch SW, the image is displayed on the liquid crystal display 9,
Further, when the projector main body 6 side is selected by the selection switch SW, it is displayed on the screen 7. And screen 7
Since the display screen size of can be freely changed, it can be viewed on a large display screen.

In the first and second embodiments, the projector body 6 is installed in the cabinet 2 of the computer body 1.
Although it is provided on the side surface, it may be provided on the front surface of the cabinet 2,
Further, in the first embodiment, it may be provided on the upper surface of the cabinet 2.

Although the projector main body 6 is provided in the cabinet 2 of the arithmetic processing section 4 in the first and second embodiments, it may be provided separately or detachably.

Further, in the first and second embodiments, the keyboard unit 3 is provided as the input unit, but both the keyboard unit 3 and the mouse may be provided, or only the mouse may be provided.

FIG. 5 shows an example in which a rear type projector is used as the display section. In FIG. 5, the personal computer has a keyboard unit 3 as an input unit, an arithmetic processing unit 4, and a rear projector 11, and the keyboard unit 3 is configured separately from the rear projector 11. The rear type projector 11 has a projector main body 13 housed in a cabinet 12 and a screen 14 provided on the front surface of the cabinet 12, and an image from the projector main body 13 is projected onto the screen 14. The arithmetic processing unit 4 is housed in the cabinet 12.

Since the OHP-compatible direct-viewing type liquid crystal display unit for presentation needs to separately prepare an OHP and a video source to be projected (personal computer or video equipment), compared to the OHP-compatible direct-viewing type liquid crystal display unit for presentation, it is a projector. The built-in personal computer is easy to use.

[0017]

As described above, according to the present invention, since the display unit of the personal computer is constituted by the front type projector including the projector main body and the screen, it is small and lightweight and the display screen is enlarged. There is an effect that a personal computer to be used for can be provided.

Further, according to another aspect of the present invention, the display portion of the personal computer is composed of the cathode ray tube or the liquid crystal display portion and the front type projector. It is possible to use the projector differently from the type projector, and by using the front type projector, there is an effect that a large display screen can be viewed.
