Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device equipped with a display device.

[0002]

2. Description of the Related Art An electronic apparatus equipped with a display device such as a word processor and a personal computer comprises a main body housing on which a circuit board and a keyboard are mounted, and a display portion housing on the upper side of the main body, on which the display device is mounted. It is equipped with. Electronic devices equipped with this display device have recently become portable, and along with this tendency, a liquid crystal display device, a plasma display device, and the like are mounted on the display unit casing to be planar. The display unit housings equipped with these display devices tend to be large in size from the viewpoint of usability, and electronic devices equipped with the display unit housings having the size of the entire main body housing have also appeared.

Conventionally, this electronic device has the configuration shown in FIGS. 16 and 17. That is, in the figure, 1 is a main body casing, and 2 is a display unit casing. A keyboard 3 is provided on the front part of the upper surface of the main body housing 1. Display housing 2
Has the same size as that of the main body housing 1 and is equipped with a display device. The rear edge portion is disposed on the upper side of the main body casing 1 and is rotatably supported by the main body casing 1 via the pivot 4, and is raised from the front edge portion side so as to be separated from the upper surface portion of the main body casing 1. So as to stand up by pivoting upward about the pivot 4 or tilting from the front edge side so as to overlap with the upper surface of the main body housing 1 and pivoting downward about the pivot 4 as the center. It has become. The display housing 2 serves as a lower surface when the housing 2 overlaps the upper surface of the main housing 1, and is a surface facing the front of the main housing 1 in which the housing 2 is erected. Display device (not shown)
Is provided.

When this electronic device is used, the display housing 2 is turned up to be started up. At this time, the display device mounted in the display housing 2 faces the front side of the main housing 1.
The operator operates the keyboard 3 mounted on the main body housing 1 while looking at the display device of the display housing 2 from the front side of the main body housing 1. It should be noted that the display housing 2 is rotated upward and is raised to define a maximum rising angle by a stopper (not shown), and is rotated further to rotate toward the rear side of the main housing 1. I try not to fall.

[0005]

However, in such a conventional electronic device, the operation of the display housing 2 is centered on the pivot 4 which is the rear edge of the main housing 1 and which is set at a fixed position. This is rotation, and the rotation is only within the range of the maximum rising angle with the upper surface of the main body housing 1, and the operation of the display housing 2 is limited. Therefore, when the operator operates the keyboard 3 of the main body housing 1 while looking at the display device of the display housing 2, the display housing 2 is displayed at a position that is easy to see when the operator operates the keyboard, specifically, the display. There is a problem in that it is not easy to use because it cannot be operated at a position closer to the front side than the rear edge of the sub-casing 2, and at that position it cannot be tilted to an angle that is easy to see.

The present invention has been made in view of the above circumstances, and when operating the keyboard of the main body housing while looking at the display device mounted on the display housing, the operator can easily see the display housing. It is an object of the present invention to provide an electronic device including a display device that can be freely and easily set in position and angle and has excellent operability.

[0007]

In order to achieve the above object, an electronic apparatus equipped with a display device of the present invention is a main body housing in which a circuit board and a keyboard are mounted and a hole is provided,
A display unit casing disposed on the upper side of the main body casing, in which the display device is mounted, and provided with a long hole along the front-rear direction, and a hinge arm disposed over the main body casing and the display unit casing. , A first shaft that rotatably supports one end of the hinge arm in the hole of the main body casing, and the other end of the hinge arm that is movably inserted in the long hole of the display casing. A second shaft that is rotatably supported, a first friction applying member that applies a frictional force between the first shaft and the hole of the main body casing, the second shaft, and the display unit. A second friction imparting member that imparts a frictional force to the elongated hole portion of the housing is provided.

[0008]

According to the above structure, when the hinge arm is rotated about the first axis which is inserted into the hole of the main body housing and supports one end of the arm, the hinge arm is inserted into the long hole of the display housing. The display unit housing supported by the second shaft that supports the other end of moves along the circular locus drawn with the length of the hinge arm as the radius. That is, the display housing moves about a first axis on a circular locus connecting the front side and the rear side of the main body. Therefore, the operator can move the display housing to a position that is easy to see when operating the display housing, for example, to a position on the front side of the main housing around the first axis.

Further, the second shaft is moved to a predetermined position along the long hole formed in the display housing, and the display housing is rotated at that position about the second shaft. The display unit housing can be tilted by displacing the second shaft, which is the fulcrum of rotation, to an arbitrary position and rotating and tilting.

The first frictional force imparting member imparts a frictional force between the first shaft and the hole of the main body casing to maintain the tilt position of the hinge arm, and the second frictional force imparting member controls the second position. The position and the inclination of the display unit housing can be held by applying a frictional force between the shaft and the long hole of the display unit housing to maintain the inclination of the display unit housing.

With such a combination of operations, when the operator operates the keyboard of the main body housing while looking at the display device of the display housing on which the display device is mounted, the operator operates the display housing with key operations. It is possible to set a position and an angle that are easy to see when performing, and it is possible to improve operability.
