Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a small electronic device used for information processing and the like, and more particularly to a small electronic device having a support mechanism for obtaining an appropriate installation angle.

[0002]

2. Description of the Related Art For a small electronic device used as an information processing device, particularly for use on a desk, a hinge for switching an installation angle of a surface of an electronic device operation surface with respect to a desk on which the electronic device is installed to an optimum position which is easy to handle. Mechanisms and stands were adopted. As a conventional small electronic device, a foldable stand mechanism is generally used for a keyboard and a tablet, and a hinge mechanism and the like are often used for a notebook computer and a palmtop personal computer.

FIGS. 13 and 14 are an exploded perspective view seen from the bottom side and a cross-sectional view of a back cover portion of the keyboard for schematically showing a conventional keyboard stand mechanism. The stand 45 is provided at a total of two places on the left and right behind the bottom surface of the back cover 47, and makes the stand 45 swingable. A stand shaft 45a serving as a center of the swing is attached to a stand bearing 49 provided on the back cover 47. It is inserted and rotatably supported on the shaft core 45d. Back cover 4
7 is formed as a leaf spring 46 utilizing its elasticity, and a groove A45b and a groove B45 provided on the stand 45 are formed.
The projection 45 at the tip of the leaf spring 46 engages with the
Is locked at a predetermined swing angle.

When the stand 45 is folded down, the convex portion of the leaf spring 46 engages with the groove A 45 b and is brought into a state of being fitted into a concave portion provided on the bottom surface of the back cover 47. When the stand 45 is raised, the convex portion of the leaf spring 46 is engaged with the groove B45c and the tip is made to protrude from the bottom surface of the back cover 47. In this state, one surface of the stand 45 is fixed to the stand cover provided on the back cover 47. The strength in the state where the stand 45 is erected is secured against the force that comes into contact with the wall 48 and presses the keyboard from above.

The stand mechanism of this keyboard is incorporated in the back cover 47, and the rocking angle at which the stand 45 is locked is in two stages, ie, standing and inverted, so that the setting angle of the keyboard surface is only two stages. . Since only the manual operation of the keyboard is considered in the angle setting with respect to the surface of the keyboard which is the operation surface and the surface of the desk which is the installation surface, there is no correspondence to the angle setting which leans to 60 degrees or more. Since the stand 45 is located in two places on the left and right,
The operation to bring them up and down is two-touch (two hand movements)
Becomes

FIGS. 15 and 16 are an exploded perspective view and a side view conceptually showing a hinge mechanism of a conventional notebook personal computer, respectively.

[0007] The electronic device main body 52 of the notebook computer is placed on a desk or the like. The liquid crystal display unit 51 is supported by the electronic device main body 52 via the hinge mechanism 50. The angle setting of the liquid crystal display surface 53 of the liquid crystal display unit 51 with respect to the installation desk upper surface can be freely adjusted by the action of the hinge mechanism 50. Also,
When the liquid crystal display unit 51 is folded on the electronic device main body 52, it becomes a cover of a notebook computer. However, one of the purposes of adjusting the angle of the hinge mechanism is to change the incident angle of the external light on the liquid crystal display surface 53 to reduce the reflected light to the operator. An operation of pressing the liquid crystal display unit 51 by hand is not considered, and the liquid crystal display surface 53 falls down because the angle holding force of the hinge mechanism 50 cannot withstand a large force of pressing the liquid crystal display unit 51 by hand.

[0008] As conventional small electronic devices other than those described above, Japanese Patent Application Laid-Open No. Hei 8-16522 and Japanese Patent Application Laid-Open No.
There is a device for supporting a 251328 portable computer.

[0009] In these conventional small electronic devices, devices that operate the surface of the device by hand, such as a keyboard, have specialized functions and structures, and the liquid crystal display surface is visually observed like a notebook computer. When confirming, it has such a specialized function and structure. Therefore, conventionally, there was no small electronic device having a function and structure for both manual operation of the surface of the small electronic device and visual confirmation of the surface, and in some cases, a stand mechanism capable of selecting either of them. . In other words, when the surface of a small electronic device is ergonomically operated by hand, the surface is set at 5 to 1 degree with respect to the installation surface.
Although it is necessary to be able to fix at about 5 degrees, when visually observing the surface of the small electronic device, the angle of the surface to the installation surface needs to be about 60 degrees, and both of these two types of setting angles are obtained. There have been no small electronic devices that can be used in the past.

[0010]

As a conventional problem, when the operation surface is manually operated, the angle of the operation surface can be fixedly set by changing the angle of the operation surface in two or more steps from about 5 degrees to about 15 degrees, and In some cases, there has been no small electronic device having an integrated stand function having both of the functions described above, which has a function of setting the operation surface at an angle of about 60 degrees. For this reason, even when the user wants to switch the inclination angle of the operation surface and select the best angle for the operation when operating the small electronic device, he cannot do so. That is, there has been a problem that a sufficient installation environment when a user uses a small electronic device cannot be provided.

SUMMARY OF THE INVENTION An object of the present invention is to solve the conventional problems. When the user operates the electronic device by hand, the installation angle of the operation surface is switched from 5 degrees to about 15 and the angle is changed at each angle. It is an object of the present invention to provide an integrated small electronic device having a function of being fixed and capable of performing a visual operation on an operation surface by switching an installation angle to about 60 degrees.
