Abstract

PURPOSE:To improve the operability of a personal computer by providing the hinge parts at both ends of a cover part, securing the connection between the cover part and a main body part via the hinge parts at the rear end part of the main body part, and making the cover part turnable toward the main body part up to 180 deg.. CONSTITUTION:The hinge parts 6a and 6b are provided at both ends of a cover part 4 and connected to a main body part 2 at the rear end of the part 2. Thus the part 4 can be smoothly turned within a range up to 180 deg. as shown by the dotted lines. Then the part 4 can be turned and fixed at an optional angle within 180 deg.. Thus a user can use a computer with the part 4 fixed at an optional opening angle within 180 deg.. Then the part 4 can be opened at the most easy-to-see angle and therefore the operability of the computer is improved.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a laptop-type personal computer that has almost the same functions as a desktop-type personal computer and can be easily carried. .

[Conventional technology]

Fig. 2 is a perspective view of a typical laptop personal computer currently on the market with the lid open, and Fig. 3(a) shows the lid of Fig. 2 with the lid closed. The rear view (b) is a plan view of the lid shown in FIG. 2 with the lid closed. 2 and 3, a keyboard 60 is provided on the surface of the main body 52, and a liquid crystal display 72 is provided on the surface facing the keyboard 60 when the lid 54 is closed.
is provided. The main body part 52 and the lid part 54 are connected by hinge parts 56a and 56b.

- The main body section 52 is provided with a floppy disk drive device 62 inside its right side, and a battery compartment 64 and a modem storage section 68 at the rear of the hinge sections 56a and 56b. Furthermore, most of the main circuits are included inside the main body portion 52.

When the lid body portion 54 is closed as shown in FIG. 3, the entire size is approximately the same as a general book or magazine, so it is also called a book-type personal combiator.

[Problem to be solved by the invention]

As shown in FIG. 2, a conventional laptop-type personal computer has a battery compartment 64 and a modem storage part 68 at the rear of hinge parts 56a and 56b.

Therefore, these limit the rotation angle of the lid 54, and the angle at which the lid 54 can be rotated when opened is approximately 135 degrees. This angle of 135 degrees is not a problem when using the main body on a desk. However, when using the device outdoors or while riding on a vehicle, the person's line of sight is not perpendicular to the liquid crystal display section 72, and the contents displayed on the liquid crystal may not be clearly visible.

Practically speaking, from an ergonomic point of view, using a lamp-top personal computer on your lap requires
It is desirable that the opening angle of the lid body portion 54 be at least 155 degrees.Therefore, despite the name "laptop", conventional laptop personal computers are used rather than being used on the lap. However, there is a tendency that the use is essentially limited to desktop use.

The present invention has been made based on the above circumstances, and provides a laptop-type personal computer that has an easy-to-read liquid crystal display when placed on the lap and is easy to use when used outdoors or in a vehicle. The purpose is to

[Means to solve the problem]

To achieve the above object, the present invention provides a laptop-type personal computer in which a main body having a keyboard with a plurality of keys arranged thereon and a lid body having a display panel are rotatably coupled by a hinge. , the hinge parts are provided at both ends of the lid body part, the lid body part and the main body part are connected by the hinge parts at the rear end part of the main body part, and the lid body part is attached to the main body part. 1
It is characterized by being able to rotate up to 80 degrees.

[Effect]

By providing hinges at both ends of the lid and connecting the lid and main body at the rear end of the main body, the battery compartment and modem storage area are protected against rotation of the hinge. It will not be a hindrance.

Therefore, the lid can be rotated up to about 180 degrees, and the user can fix the opening angle of the lid at any angle up to 180 degrees.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the laptop personal computer according to the present embodiment with the lid section tilted approximately 135 degrees. The laptop personal computer shown in FIG. 1 includes a main body 2, a lid 4, and a pair of hinges 6a.
, 6b, the main body part 2 and the lid part 4 are connected to the hinge part 6a.
, 6b. In addition, a battery chamber 14 is provided in the main body between the hinge parts 6a and 6b, and this battery chamber 14 is different from the conventional one in which two batteries are arranged in three rows in the horizontal direction. The difference is that three batteries are arranged in two rows in a horizontal direction. As a result, the width of the battery chamber 14 is reduced, and the lid body 4
The battery chamber 14 does not become an obstacle when rotating.

A keyboard 10 is provided on the surface of the main body 2, and a floppy disk drive bag 5f12 is provided inside the right side. A liquid crystal display section 22 is provided on the surface facing the keyboard 10 when the lid section 4 is closed, and the contrast is adjusted by a contrast adjustment volume 24. It can be adjusted by the adjustment volume 26.

As shown in this figure, the hinge parts 6a and 6b are provided at both ends of the lid body part 4, and the hinge parts 6a and 6b are provided at both ends of the lid body part 4, and
is combined with For this reason, there is no obstacle in the rotation range when the lid body 4 is rotated, and therefore the lid body 4 can be rotated up to 180 degrees as shown by the dotted line in the same figure. Can be fixed at an angle.

When using a lamp-top personal computer outdoors or on a vehicle, the computer is often placed on the lap.

In such a case, the line of sight can be made almost perpendicular to the liquid crystal display section 22 by opening the lid section 4 at an optimal angle of up to 180 degrees, taking into consideration the angle of reflection of light rays from the outside. The displayed content becomes easier to see.

Further, in a normal usage mode such as on a desk, the opening angle of the lid body portion 4 can be fixed at, for example, about 135 degrees.

In this way, the angle of the lid body part 4 can be adjusted in accordance with various usage patterns, and the range of use is greatly expanded and the operability is improved.

〔Effect of the invention〕

As explained above, according to the present invention, there is no obstacle in the rotation range of the lid body that would restrict this rotation, and when the lid is used on a person's lap while riding in a vehicle or outdoors. Since the body part can be opened at an angle that is most convenient for viewing, it is possible to use a laptop-type personal computer with improved operability and a wider range of use.
