Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a uniform photographing illumination unit for photographing, for example, a commercial photograph, which is mainly used for photographing medical photographs and the like. It is.

[0002]

2. Description of the Related Art Conventionally, photographing (commercial photograph) of a product published in a product catalog or the like is performed by a special photographing space or photographing for sharpening the details of a subject or preventing a highlight portion from being generated in the subject. Because of the equipment required, they were usually performed by professional photographers familiar with their handling. For this reason, this kind of commercial photography tends to be expensive, requiring a lot of labor and high photography techniques.

[0003] In recent years, in order to save labor in such commercial photographing, photographing tables and photographing apparatuses provided with various photographing functions and lighting functions have been proposed and provided. For example, a "photographing table" described in JP-A-11-258689, an SFC Technical Cube (trade name) manufactured by SFC (company name), and a desktop lighting system D-LS820 (trade name manufactured by Photo Chemical Co., Ltd.) (Product name), Unit Studio II (product name) manufactured by Comet Corporation (company name), Creative Studio manufactured by Take (company name)
A product such as ALS-70, a desktop writing box manufactured by Light Communication Co., Ltd. (trade name) is known.

[0004] In these photographing tables and photographing devices, a plurality of columns and ceiling frames are assembled on a mounting table on which a subject is to be mounted by fitting, screwing, or the like to form a photographing space. An assembling type that is configured to fix or suspend equipment such as a screen, an illuminator, a reflector, and a light diffusing member, and a fixed type that is configured by previously incorporating each of the above equipment in a fixedly formed imaging space. Can be roughly divided into

[0005]

However, in the above-mentioned assembling-type photographing table or photographing apparatus, complicated assembling procedures and disassembly work are required to form the photographing space, and various equipments are also required to be assembled in the photographing space. Takes time. On the other hand, in a fixed type imaging stand or imaging device, since it is not itself configured in consideration of storage and carrying,
It is necessary to secure a dedicated installation space.

By the way, the present applicant has already manufactured and sold a photographing apparatus intended for use in the medical field, mainly for photographing organs and cells, copying and enlarging various medical photographs, and the like. FIG. 8 shows an example of this photographing device. The photographing apparatus 10 includes a stage 1 as a photographing table on which a subject is mounted, and a pair of left and right reflected light illuminators as illumination light sources for illuminating the subject mounted on the stage 1 from left and right. 2. A transmitted light illuminator 3 built in the lower part of the stage 1 for illuminating the subject from below, and a camera 4 for photographing the subject mounted on the stage 1.
Camera stage 5 with stage fixed, stage 1
Is provided with a foot switch 6 for moving up and down by electric power. With this photographing device, a three-dimensional object (for example, 30 cm ×
Digitizing up to 30 cm x 30 cm) is possible.

Therefore, the present inventor has proposed a configuration in which the photographing apparatus is capable of photographing the above-mentioned subject for commercial photography.
We considered adding a new application to the photographing device.
As a result, in order to photograph a subject for commercial photography using the photographing apparatus as described above, the subject placed on the stage 1 must be uniformly positioned so that highlights reflected from the subject are not reflected. It became clear that lighting was necessary. In particular, when the subject was photographed with a digital camera, the dynamic range corresponding to the latitude in silver halide photography was narrow, so that the photograph became extremely prominent due to very slight unevenness in illuminance of the subject.

As a method for solving such a problem, for example, a photo-diffusion box having light-diffusing plates on both the left and right sides and the upper surface of the photographing space on the stage 1 or the photographing space is taken. The apparatus is placed on the stage 1 of the apparatus, the object is placed in a light diffusion box, and the illumination light from the reflected light illuminator 2 as an illumination light source is uniformly illuminated on the object through a light diffusion plate to diffuse light It is conceivable to photograph the subject from the front of the box.

However, the light-diffusing box is an attachment that is required only when a commercial photographing object is photographed using the above-described photographing device. It is unnecessary when used in the original medical field as a photographing device. Therefore, when the light diffusion box having a relatively bulky structure as described above is used as an attachment attached to the photographing device at the time of taking a commercial photograph, the photographing device is required to be used in the medical field. When used in, for example, such a light diffusion box, it becomes an obstacle.

Therefore, the present applicant can easily form a light diffusing box for uniformly illuminating a subject when used, and can easily fold it into a panel when not in use. A patent application was previously filed for a uniform lighting unit for photography that has a structure that is easy to handle and does not bulk during storage. An invention according to Japanese Patent Application No. 11-355286 is provided on a photographing table of a photographing apparatus including a photographing table for mounting a subject and an illumination light source for illuminating the subject mounted on the photographing table. A uniform illumination unit for photographing for uniformly illuminating the subject, a pair of light diffusing plates for diffusing illumination light to the subject, and a holding frame for holding each light diffusing plate. An upper surface link having a central portion pivotally supported and both ends pivotally supported on the upper surface side of each holding frame; and a central portion pivotally supported and both ends pivotally supported on each holding frame. And a back side link rotatably supported on the back side of the vehicle.

The present invention is an improvement of the invention according to the above-mentioned application, in which the structure is further simplified, the handling is simpler, and the rigidity in an assembled state for use is improved. It is an object of the present invention to provide a uniform photographing illumination unit.

[0012]
