Description

Camera support structure of a real imager and a real imager provided with the same

The present invention relates to a camera rotating structure of an actual imager, and an actual imager having the same, and more particularly, to a camera rotating structure of an actual imager improved to support a camera rotatably, and an actual imager having the same. will be.

In general, a real imager is a device for capturing an object with a charge coupled camera and displaying it on a monitor, and is a device widely used for academic and industrial purposes. In particular, by combining a lens that can magnify a real object, such as a microscope lens, to a CD camera that captures an object in a real imager, an image in which a fine object is enlarged can be displayed through a monitor. The real imager includes a variety of peripheral devices, for example, a separate device for illuminating the real to improve the clarity of the image displayed on the monitor.

The real imager may be manufactured in various forms in the structure supporting the CD camera. The support structure of the real imager must have access to the real object from various angles so as to most effectively display the three-dimensional shape of the real object to be imaged. That is, it is preferable that the support structure of the real imager has multiple axes of freedom. However, the real imager according to the prior art has a limited degree of freedom, and thus there is a problem in that the actual imaging angle is limited.

According to one example of the prior art, one or two supporters are fixed to one side of a table that mounts a real object as a subject, and a camera head is fixed to an end thereof. Such a fixing method has an advantage that the camera can be stably maintained, but there is a problem in that an input of an image is inconvenient or limited when a volume of a real object which is a subject is large or an area is large.

According to another example of the prior art, the camera head was fixed to the end by installing the support inclined diagonally from one side of the table. In this example, it is possible to reduce the size of the table to be mounted on the real object, but it is difficult to accurately match the camera to the center of the table, and thus, a number of additional parts are required to compensate for such a problem. .

On the other hand, in the real imager disclosed in Japanese Patent Laid-Open No. 7-107377, two supports for supporting the camera are rotatably installed through the joints. That is, the first support may be rotated with respect to the table and the second support, and the second support may be rotated with respect to the first support and the camera. However, in the real imager disclosed in the Japanese Patent Laid-Open Publication, there is a disadvantage in that the camera must be separated when stored without using the real imager. This is because the first support and the second support can be rotated only in the same direction, and therefore the second support is not properly folded on the table due to the volume of the camera when the second support is brought close to the table.

On the other hand, in the Japanese patent, the action of the lock button which performs the locking action in the rotation between the supports is involved. The user can only rotate by pressing the lock button to release the locking action. If you do not support the camera or support with one hand when you press the lock button, the camera may fall on the main unit. Therefore, there is a risk of breakage, which causes inconvenience in use.

The present invention is devised to solve the above problems, and an object of the present invention is to provide an improved camera support structure of a real imager, and a real imager having the same.

Another object of the present invention is to provide a camera support structure of a real imager which is easy to use and store, and a real imager having the same.

Another object of the present invention is to provide a support structure of a real imager in which the support position of a camera can be freely changed, and a real imager having the same.
