Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a document data input device, and more particularly to a document data input device having a foldable electronic image pickup device.

[0002]

2. Description of the Related Art In recent years,
2. Description of the Related Art A document data input device that captures a document using an electronic image pickup device and inputs the document as document data has been widely used. The document data input to such a document data input device is used by being enlarged and projected on a screen by a projection device or input to a personal computer for processing.

FIG. 3 shows an example of a conventional configuration of such a document data input device to which the present invention is applied. In FIG. 3, the document data input device includes a base 1 having a surface on which a document is placed, and a support 2 having one end supported by the base 1 and the other end supporting a camera 4 as an image pickup device. Installed. The support portion 2 has a mounting screw 3 at the tip, and an imaging camera 4 is mounted on the support portion 2 with the screw 3.

[0004] The imaging lens 5 of the imaging camera 4 is directed to the surface of the base 1 on which a document is to be mounted in use. Therefore, it is possible to capture an image of a document by the imaging camera 4.

[0005] In such a document data input device, the imaging camera 3 is bent by bending the supporting portion 2 so that the base portion 1 is moved.
Can be folded in parallel.

In such a document data input device, the imaging camera 4 photographs a document placed on the upper surface of the base unit 1,
The signal is converted into a digital signal by a circuit (not shown) and output. The output digital signal is input to a personal computer or input to a projector.

In the conventional document data input device shown in FIG. 3, when the external light 7 is taken into consideration, the light source of the external light 7 is reflected on the document placed on the base 1 and photographed by the imaging camera 4. The resulting document does not necessarily have a uniform illumination intensity than the external light 7.

Accordingly, document data captured by the image capturing camera 4 is distorted. In view of the above, an object of the present invention is to provide a novel document data input device which avoids the influence of the external light 7 in the conventional document data input device.

[0009]

The basic structure of the present invention for solving the above-mentioned problems of the present invention is as follows: a base portion, one end of which is supported by the base portion, and an imaging camera which is supported by the other end portion; A support portion that can be folded into the portion, and a lid portion that covers the base portion in a state where the support portion is folded.

Further, in another embodiment according to the present invention, a base portion, a support portion having one end supported by the base portion, supporting an imaging camera at the other end portion, and being foldable on the base portion;
In a state in which the support portion is folded, the support portion covers the base portion, and has a pair of lid portions each having one end attached to a peripheral portion of the base portion. It is characterized in that the other end is configured to be in contact at the center position.

Further, as a specific measure, in any one of the above-described configurations, an illumination lamp is arranged inside the lid.

[0012]

Embodiments of the present invention will be described below with reference to the drawings. In the drawings, the same or similar components will be described with the same reference numerals.

FIG. 1 is a diagram showing a first embodiment of the present invention.

FIG. 1A is a side view of a document data input device according to the present invention. Particularly, the state where the lid 6 is closed is shown.

FIG. 1B is a side view of the document data input device according to the present invention with the cover 6 opened.

The document data input device according to the present invention has a lid 6 which is supported at one end by a support screw 61 on the base 1 of the document data input device. Therefore, FIG. 1A shows a state in which the cover 6 is closed and the base 1 of the document data input device is covered.

FIG. 1B shows a state where the lid 6 is opened in the direction of the arrow. The lid 6 is supported by support screws 61 and attached to the base 1 of the document data input device by hinges 63.

FIG. 1B shows a state in which the photographing camera 4 is attached to the tip of the column 2 and the column 2 is raised. An imaging camera lens 5 is attached to the imaging camera 4 with the imaging camera lens 5 facing the upper surface of the base unit 1.

Therefore, when a document is placed on the upper surface of the base unit 1 of the document data input device, the camera 4 can shoot the document through the camera lens 5.
A document imaged by the imaging camera 4 is converted into a digital signal by a circuit (not shown) and output.

Here, the feature of the embodiment of the present invention shown in FIG. 1 is that, in a state in which the lid 6 is opened, that is, in a state where the imaging camera 4 is attached to the tip of the support column 2 and pulled up, the input of document data is performed. The apparatus is in a use state for photographing a document placed on the base unit 1 of the apparatus.

In this state of use, the cover 6 has an illuminating lamp 60 inside it, and illuminates a document placed on the upper surface of the base 1. Therefore, the imaging camera 4 can image a document at a sufficient illuminance.

Here, in the present invention, the external light 7 is blocked by the lid 6, and is applied to a document placed on the base 1.
Irradiation with the external light 7 can be prevented. Therefore, the brightness of the imaging camera 4 is controlled only by the illumination by the illumination lamp 60 mounted inside the lid 6. Thereby, the imaging camera 4 can image a document placed on the base unit 1 with uniform illuminance.

FIG. 2 is a diagram showing a second embodiment of the present invention. The features different from the first embodiment of FIG.
This is a point that a pair of lids 6 divided into two at substantially the center position of the base 1 is formed. The other end of each of the pair of lids is attached to the base 1 of the document data input device by support screws 61. This state is shown in FIG.

FIG. 2B shows a state in which the pair of lids 6 are raised in the directions indicated by the arrows and in directions opposite to each other. Further, the imaging camera 4 is started up by the tip of the column 2, and is in a state of capturing a document placed on the base 1.

Hinges 62 and 63 are attached to portions of the pair of lids 6 connected by the support screws 61 so as to connect to the base 1.

An illumination lamp 60 is provided on each of the pair of lids 6.
Is mounted inside.

Therefore, in the embodiment of FIG. 2, it is possible to illuminate the document placed on the base 1 from both sides by the illumination lamp 60.

Therefore, it is possible to give more uniform illumination to the embodiment of FIG. Further, the lid 6 can block light from the external light 7 as in the embodiment of FIG.

Further, since the pair of lids 6 are opened in opposite directions, the external light 7 exists on the right side in FIG. 2, but even when the external light 7 exists on the left side, the external light 7 Light 7 can be blocked.

In the present embodiment, the lid 6 is the base 1
However, it is needless to say that a configuration may be adopted in which the support 2 is attached.

[0031]

As described above, according to the embodiment, the present invention has the lid 6, and the imaging camera can be folded and stored inside the lid 6. Therefore, the lid 6 is opened in the use state.

Accordingly, the external light 7 can be shielded, and the external light 7 can be prevented from being reflected on a document placed on the base 2.

From this point, the document data input device of the present invention can capture and read document data with more uniform illumination.
