Abstract

PROBLEM TO BE SOLVED: To obtain a tilting mechanism which eliminates a need of operating a movable leg separately when an electronic apparatus is operated and carried by a method wherein the movable leg which is installed at the bottom part of an electronic apparatus body and which is interlocked with a display opening and shutting operation is provided. SOLUTION: First, in a state that a display 1 is shut, a movable leg 3 is pressed to, and housed in, the small-radius part of a cam 6 by the pressure force of a spring 7 and by a reaction force from the bottom face of an installation place due to the own weight of an electronic apparatus body. Then, the display 1 is opened, its movement is transmitted to a gear 5 from a gear 4, the cam 6 is turned, the radius of the movable leg 3 and that of the cam 6 are increased, the movable leg 3 protrudes from an enclosure bottom part 8, the display 1 is opened, the movable leg 3 comes into contact with the large- radius position of the cam 6, the movable leg 3 presses the bottom face of the installation place, and the electronic apparatus body is tilted. In addition, when the display 1 is closed, the movable leg 3 is housed at the 'inside of the enclosure bottom part 8 by the reaction force from the bottom face of the installation place and by the pressure force of the spring 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device, and more particularly to a portable electronic device having a flat panel display.

[0002]

2. Description of the Related Art Conventionally, this type of electronic equipment has a movable leg portion as disclosed in Japanese Utility Model Laid-Open Publication No. There is an apparatus provided with an inclination mechanism for adjusting the inclination by using the above.

[0003]

However, in a conventional electronic device having a movable leg, since the movable leg and the opening / closing of the display are not linked, in addition to opening / closing the display when operating and carrying the mobile device, the conventional electronic device has a movable leg. The legs had to be operated separately.

It is an object of the present invention to provide an electronic device tilting mechanism in which a mechanism for linking the opening and closing of the display and the movable leg is interlocked, so that there is no need to separately operate the movable leg during operation and carrying.

[0005]

In order to achieve the above object, the present invention provides an electronic device tilting mechanism for tilting an electronic device body having an openable / closable display at an angle suitable for device operation. It is characterized in that it has a movable leg provided at the bottom of the electronic device body and interlocking with a display opening / closing operation. Specifically, it has a gear directly connected to the display and a cam directly connected to the gear meshing with the gear, the movable leg is pressed by the cam by an elastic body, and the movable leg is moved by the opening operation of the display. The electronic device tilting mechanism is configured to push the legs toward the floor of the installation site and store the movable legs in the bottom of the housing by closing the display.

In the invention described above, the cam is linked to the opening and closing operation of the display by a gear, and the cam is linked to the movable leg. Therefore, when the display is opened, the cam rotates to push the movable leg, whereby the tilt of the electronic device is obtained, and the movable leg is stored when the display is closed.

Further, when the display is opened at an angle within a predetermined range with respect to the electronic device main body, since the outer shape of the cam which comes into contact with the movable leg is a circle having a constant radius, the movable leg is moved by an external force. Even if pressed, the cam will rotate,
The display never closes. In this range, the movable leg is not extended, and the inclination of the electronic device main body is constant.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is an external view of an electronic device showing an embodiment of an electronic device tilting mechanism according to the present invention. FIG. 1A shows a state in which a display 1 is closed with respect to an electronic device main body 2.
(B) shows a state where the display 1 is opened with respect to the electronic device main body 2.

As shown in FIG. 1, the electronic apparatus comprises an openable display 1 and a main body 2;
When the display 1 is closed as shown in FIG.
Are in the electronic device body 2. On the other hand, (b)
When the display 1 is opened as shown in FIG. 1, the movable leg 3 extends from the electronic device main body 2 and the electronic device is tilted.

The components for interlocking the movable leg 3 with the opening / closing of the display 1 will be described. FIG. 2 is an exploded perspective view showing components of one embodiment of the present invention. The display 1 is directly connected to the gear 4 as shown in FIG. 2, and the gear 4 meshes with the gear 5 directly connected to the cam 6. One end of the movable leg 3 pressed by an elastic body 7 such as a spring or rubber is in contact with the cam 6, and the elastic body 7 is sandwiched between the flange of the movable leg 3 and the housing bottom 8. The other end of the movable leg 3 can protrude from a hole in the housing bottom 8.

Here, the positional relationship of the cam 6 with respect to the display 1 and the movable leg 3 will be described with reference to FIG. FIG. 3 is a side view cut in order to show an operation state of an embodiment of the present invention in detail. FIG. 3A shows a state in which the display 1 is closed. In this state, the movable leg 3 is
And is stored in the housing bottom 8. FIG. 3B shows a state in which the display 1 is opened 90 degrees with respect to the main body, and FIG. 3C shows a state in which the display 1 is opened 180 degrees.
In these states, the movable leg 3 is in contact with the cam 6 at a large radial position, and the movable leg 3 protrudes from the housing bottom 8.

The operation of the tilt mechanism according to the present embodiment will be described in detail with reference to FIG.

First, as shown in FIG.
Is closed, the movable leg 3 is pressed against the small radius portion of the cam 6 by the pressing force of the spring 7 and the reaction force from the floor of the installation location due to the weight of the device main body, and is stored.

Next, when the display 1 is opened, the movement is transmitted from the gear 4 to the gear 5, and the cam 6 rotates,
The radius of the cam 6 at the contact portion between the movable leg 3 and the cam 6 gradually increases, and the movable leg 3 protrudes from the housing bottom 8 against the pressing force of the spring 7 and the reaction force from the floor, and FIG. When the display 1 is sufficiently opened as shown in (b) and (c), the movable leg 3 is in contact with the large radius position of the cam 6, and the movable leg 3 pushes the floor of the installation location to move the electronic device body. Incline. In addition, the opening operation of the display 1 as shown in FIGS.
To the contrary, since the outer shape of the cam 6 is a circle having a constant radius, the cam 6 does not rotate and the display 1 does not close even when the movable leg 3 is pressed by an external force. After the display 1 is opened at 90 degrees, the movable leg 3 is not extended, and the inclination of the electronic device main body is constant.

When the display 1 is closed, the movement is transmitted to the gear 4, the gear 5, and the cam 6, and the radius of the cam 6 at the contact portion between the movable leg 3 and the cam 6 is gradually reduced. The movable leg 3 is housed inside the housing bottom 8 by the reaction force from the floor and the pressing force of the spring 7.

According to the above embodiment, the operation of manually raising and storing the movable legs can be omitted.

[0018]

The present invention is an electronic device tilting mechanism for tilting an electronic device body having an openable / closable display at an angle suitable for device operation, and is provided on the bottom of the electronic device body. By providing the movable leg that is interlocked with the opening / closing operation, it is not necessary to separately tilt the electronic device when using the electronic device, that is, when opening the display.
