ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a storing structure, and more particularly to a storing structure for a document.
BACKGROUND OF THE INVENTION
Generally, a document camera is used to be a peripheral equipment in a liquid crystal projector. For picking up an image of a document, the document camera is performed in a working condition as shown in
FIG. 1. A
document camera
10
includes a camera
15
, a base
13
, an extensible arm
11
having a first hinge
12
connected to the base
13
and a second hinge
14
connected to the camera
15
, and two elongated plates
16
(only one shown in
FIG. 1
) for supporting the camera
10
. When the document camera
10
is not at working condition, the document camera
10
is stored as shown in FIG.
2
. Therefore, the structure of the document camera according to the prior art is space-consumption and also difficult to carry.
Therefore, the purpose of the present invention is to develop a storing structure for a document camera to deal with the above situations encountered in the prior art.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to propose a storing structure for a document camera for reducing space-consumption.
It is therefore another object of the present invention to propose a storing structure for a document camera for conveniently carrying.
According to the present invention, there is proposed a storing structure for a document camera. The storing structure includes a camera for picking up an image of a document and having a first lateral side, an extensible arm pivotally connected to the first lateral side of the camera for adjusting a distance between the camera and the document, a base having a second lateral side pivotally connected with the extensible arm for supporting the camera, a first pivot device connected to the first lateral side of the camera and the extensible arm for pivoting the camera, and a second pivot device connected to the extensible arm and the second lateral side of the base for pivoting the extensible arm to store the document camera.
Preferably, the first pivot device includes a first pivoting shaft disposed on one end of the extensible arm for pivoting the camera, a first inner sleeve fastened on the first pivoting shaft for transferring a pressure from the camera to the first pivoting shaft, and a first outer sleeve disposed on the first inner sleeve and connected to the camera for transferring the pressure from the camera to the first inner sleeve. The second pivot device preferably includes a second pivoting shaft disposed on the other end of the extensible arm for pivoting the extensible arm, a second inner sleeve fastened on the second pivoting shaft for receiving a pressure from the second pivoting shaft, and a second outer sleeve disposed on the second inner sleeve and connected to the base for transferring the pressure from the second pivoting shaft to the base.
Certainly, the first pivoting shaft and the second pivoting shaft can be integrally formed with the two ends of the extensible arm, respectively.
