 Next, the configuration of an embodiment of the present invention will be described with reference to the drawings. On a bracket 2 mounted on one side of the upper surface of a flat base 1 on which an object is placed, a camera support arm 4 which is extendable and retractable via a fixed shaft 3 is rotatable about a fixed shaft 3 and a notch (not shown) is provided. It is mounted by a mechanism so that it can be positioned and stopped in the one-dot chain line state and the solid line state in FIG. 2, and a video camera 5 is rotatable around an axis 6 and a notch not shown is attached to the tip end of the camera support arm 4. It is mounted so that it can be positioned and stopped by the mechanism in the state of the one-dot chain line in FIG. 2 in which the lens is oriented horizontally and in the state of the solid line in FIG. 3 in which the lens is oriented directly below.

A cover 7 is attached to the one side of the base 1, and a scale-equipped moving rail is provided on the other side opposite to the one side using a groove 8 formed on the side surface of the base 1 as a guide. -When the rail 9 is reciprocally mounted in parallel between the one side and the other side, and the moving rail 9 is located at the other side position of the base 1, the edge heights of both sides of the base 1 When the moving rails 9 are the same and are between the one side and the other side of the base 1, the moving rails 9 are located above the base 1 with their lower surfaces being close enough not to rub against the upper surface of the base 1. 5 and is a positioning pad for the image film, for example, the slide film 10, as shown in FIG.

An upper surface plate 11 forming the upper surface of the base 1, in this case, a semi-transparent plate having an extremely low light transmittance, for example, a methacrylic resin of Mitsubishi Rayon, Acrylite # 001 Fine Matte 2 mm thick semi-transparent plate On the back side of the face plate 11, a backside lighting fixture 12 for irradiating the slide film 10 placed on the back side of the top plate 11 at a shooting position on the top plate 11 so that the video camera 5 can shoot the film. In this case, the base film illuminator 12 having the discharge lamp 15 driven by the well-known high frequency lighting circuit 14 is attached to the reflector 13 having the maximum size of the slide film 10 to be projected, and the irradiation area of the slide film 10 on the top plate 11 is attached. In addition to illuminating only the frame shape, the light from the discharge lamp 15 is guided by the optical fiber cable 16 so as to have a writing size of, for example, A3, A4, B4, B. Instructing Ma indicating the like - click are displayed in characters and the like relief by the light spot or light.

The camera support arm 4 which is rotatable about the fixed shaft 3 has a cylindrical inner arm 4B inserted in the cylindrical outer arm 4A and an outer arm 4A. The length of the camera support arm 4 can be set to an arbitrary length by tightening the screw body 18 attached to the inner arm 4B through the longitudinal groove 17 formed in the arm 4A. In this case, in particular, the flat cable 19 passing through the retractable camera support arm 4 has a base end portion (see FIGS. 9 and 10) of the outer arm 4A at a portion passing through the outer arm 4A. The left side) is fixed to the insulating material attachment plate 21 fixed with the screw 20 via the clip 22, and the posture of the inner arm 4A inner flat cable 19 regardless of the reciprocating movement of the inner arm 4B. Hold the camera at a constant position and hold the slider when the camera support arm 4 expands or contracts. It is designed so that excessive bending force is not applied to the table 19.

Next, the operation of this embodiment will be described. When a normal printed matter or a sample product such as a wrist watch or a ring is projected on the video camera photographing stand 23 configured as described above, the printed matter is placed on the photographing position on the base 1 and the video camera 5 is turned on. By doing so, an image of a printed matter or the like can be projected on a television receiver (not shown). When the slide film 10 is then projected, the lighting device 12 behind the base of the video camera shooting stand 23 is not shown. When turned on, the size of the slide film 10 at the shooting position on the base 1 shines brightly, and when the slide film 10 is placed on this shining part, the slide film 10 is illuminated from the back side and is displayed on the TV receiver. It is clearly projected.

In this case, after the moving rail 9 is moved along the groove 8 to an appropriate position for photographing, one side of the slide film 10 is brought into contact with the moving rail 9 to slide the slide film 10. The film 10 can be taken in a distortion-free posture, and in particular, the scale on the moving rail 9 is evenly scaled to the left and right with the center set to 0. In addition to the easy positioning of the slide film 10, the image magnification of the slide film 10 can be easily known from the scale of the moving rail 9 and the screen size of the television receiver. Positioning the slide film 10 in the left-right direction by appropriately forming a left-right direction positioning means such as forming a stepped recess having a slight incision into the moving rail 9 on one side of the moving rail 9. It can also be easier.

When a printed matter or the like is placed on the base 1 at a photographing position, an instruction to indicate a document size, for example, A3, A4, B4, B5, etc., is given by turning on the base back lighting device 12 by operating a switch (not shown). After turning on the mark and aligning printed matter, etc., the back lighting unit 12 can be turned off as necessary, and then the image can be displayed on the TV receiver. In some cases, the instruction mark can be displayed. The lighting can be independent, and in particular, the surface of the base 1 can be used as a white plate by adopting the lighting system of the instruction mark. In addition, as shown in FIG. By mounting the monitor TV receiver 24 on the cover 7 portion of the stand 23, it is possible to easily set the position and orientation of the writing, the slide film 10, and the like.
