Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image input device used by connecting to a video signal transmitting device or an image processing device, and more specifically, when a still subject is photographed by a video camera. The present invention relates to a photographing device used.

[Background of the Invention]

Conventionally, an image input device having a structure shown in FIG. 3 is known as an image input device for capturing a still image of a still image with a video camera and inputting the image of the object to an image processing device or the like.

In FIG. 3, reference numeral 13 denotes an object whose upper surface is a document to be read.
It is a horizontal base that is a mounting surface of 14, and vertical columns 15 are erected on the base 13. A horizontal arm 16 extending in parallel with the mounting surface is formed at the upper end of the supporting column 15 integrally with the supporting column 15, and a subject 14 on the mounting surface is photographed on the lower surface of the horizontal arm 16. An imaging device 17 including an imaging lens and an imaging element for performing the operation is fixed.

In the image input device having the above-described structure, the distance between the subject 14 on the base 13 and the photographing device 17 is considerably large and the distance is constant. It was necessary to place a high platform 18 on the platform 13 and place a subject on the platform 18, or to equip the photographing device 17 with a long-focus imaging lens. As a result, the entire volume of the device becomes considerably large, so that not only a large storage space is required but also the device is troublesome to handle. Further, when a long-focus imaging lens is used instead of using the base 18, there are drawbacks that the handling becomes more troublesome, the number of interchangeable lenses increases, and the cost of the interchangeable lenses becomes expensive. . For example,
When it is possible to scan up to A4 size originals and a single screen using the long focus lens, the imaging lens and the subject (original)
Since a 8.3x focal length ratio is required to display the Leica film on the full screen without changing the distance to and, in this case, a zoom lens may be used, but the zoom lens is very large. Moreover, it is expensive and expensive. Further, although an interchangeable lens may be used, at least two interchangeable lenses must be prepared, so that there is a drawback that the apparatus price including the interchangeable lens becomes very expensive.

[Object of the Invention]

It is an object of the present invention to provide an image input apparatus which does not require mounting of the above-mentioned stand or lens exchange when performing close-up photography.

[Outline of Invention]

In the image input apparatus according to the present invention, a window is provided through an intermediate portion of a vertical column upright on a base, and an upper end of the vertical column supports a photographing device that can rotate between a horizontal position and a vertical position. A member is pivotally mounted, and a photographing device including an imaging lens and an image pickup device is mounted on the photographing device supporting member at a position corresponding to the window, and the subject supporting device for close-up photographing is close to the window. Is provided. With the image input device of the present invention, close-up photography is possible only by the operation of positioning the photographing device support member at a vertical position,
Further, by making the photographing device supporting member vertical, the space required for storage can be made small.

Example of Invention

An embodiment of the present invention will be described below with reference to FIGS. 1 and 2 of the accompanying drawings.

FIG. 1 is a diagram showing a first embodiment of an image input device according to the present invention. Reference numeral 4 is a base whose upper surface is a surface on which the first subject 5 is placed, 3 is a vertical column which is erected on the base 4 and has a window 3a formed in the middle thereof, and 2 is a dotted line , Which is pivotally attached to the upper end of the vertical column 3 so as to be pivotable between the horizontal position shown by 1 and the vertical position shown by the solid line, 1 is attached to the window 3a on the lower surface of the support member 2. An image pickup device including an image pickup device and an image forming lens attached at a position to be inserted, and 6 is a second object support base provided on the base 4 in the vicinity of the window 3a and adjustable in elevation.

In the apparatus of the present embodiment, when the first subject 5 (read original) is photographed, the photographing device support member 2 is held at the position of the dotted line in FIG. 1 to photograph the subject 5, and the close-up photographing is performed. When performing, the subject to be photographed is placed on the support base 6 and the support member 2 is held at the position indicated by the solid line in the figure.

FIG. 2 is a schematic diagram of an image input apparatus according to a second embodiment of the present invention, and the same reference numerals as those in FIG. 1 are the same components as those of the apparatus of FIG.

In FIG. 2, 8 is a Leica plate film which is a second subject, 7 is a film holder, 12 is a diffuser plate such as frosted glass, 11 is a mirror, 10 is a focusing lens, and 9 is a light source.

The apparatus shown in FIG. 2 is characterized in that the close-up photographing subject is a film or the like, and is provided with the illuminating device as shown in the drawing.

It is needless to say that the structural portion supporting the lighting device and the film holder may be configured to be capable of moving back and forth and moving up and down with respect to the photographing device 1.

〔The invention's effect〕

As described above, the image input device of the present invention does not require a stand for close-up photography and does not require an interchangeable lens, and thus is easy to handle. Moreover, the apparatus price can be reduced as compared with the case where an interchangeable lens is required, and the space required for housing the apparatus can be reduced when the photographing device support member 2 is in the vertical position.
