JPS63271215A - Television camera device for optical observation device - Google Patents

Abstract

PURPOSE:To easily connect a camera head and to spread the video observation of an object to be observed by providing a fitting means with a means to be coupled with respective lens barrels having different fitting size. CONSTITUTION:The camera head is fitted to the lens barrels 12, 13 of a microscope 11 through a camera holder 17. The camera holder 17 can be switched to a lens barrel with different fitting size, e.g. an eyepiece lens barrel 12 and a camera lens barrel 13, by properly replacing and using a mounting part 24A or 24B. Thereby, video observation can be executed also by a microscope having no camera lens barrel 13. Consequently, the camera head 18 can be easily connected to various optical observation devices and the video observation of object to be observed can be spread.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a television camera device for optical observation devices such as microscopes and endoscopes.

[Prior Art] Conventionally, a television camera device in which a camera head is attached to a lens barrel of a microscope has been used for clinical examinations, research, practical guidance, and the like. According to this television camera device, for example in the operating room! The specimen set in the III microscope can be imaged with a camera head, and the imaged results can be observed on a monitor TV installed in a remote laboratory or recorded on a videotape using a video tape recorder. becomes.

[Problem to be Solved by the Invention 1] However, in the conventional television camera device, the camera head is attached to a dedicated camera lens barrel provided on the microscope. For this reason, a camera head cannot be attached to a microscope that is not equipped with a dedicated camera lens barrel, and those
With the A-microscope, it is not possible to perform the above-mentioned observation using a monitor television or recording using a video tape recorder.

Furthermore, the camera head can only be attached to a camera lens barrel of a specific mounting size. For this reason, even if the microscope is equipped with a lens barrel dedicated to a camera, a camera head other than a camera head that is compatible with the mounting size cannot be applied, and it is difficult to use the camera head in combination with multiple microscopes.

The present invention aims to popularize video observation of iSl objects by easily connecting a camera head to various optical observation devices.

[Means for Solving the Problems] The present invention provides a television camera device for an optical observation device in which a camera head is attached to an observation lens barrel of an optical observation device by an attachment means. The attachment means is provided with means that can be coupled to lens barrels of different attachment sizes.

[Effect]

According to the present invention, the attachment means for attaching the camera head to the lens barrel can be attached to each of the lens barrels of different attachment sizes.

Therefore, camera heads are not limited to lens barrels exclusively for cameras.
It can also be attached to an eyepiece barrel or the like having a different mounting size from the camera-specific lens barrel, and video observation can be performed even with an optical observation device that is not equipped with a camera-specific lens barrel. In addition, the camera head can be attached to lens barrels of different attachment sizes, so
Can be used with multiple optical observation devices.

That is, the camera head can be easily connected to various optical observation devices, and video observation of objects to be observed can be popularized.

[Example] Fig. 1 is a sectional view showing the main parts of a television camera device according to a first embodiment of the present invention, Fig. 2 is an exploded sectional view showing a camera holder according to the first embodiment, and Fig. The figure is a perspective view showing the camera holder, and FIG. 4 is a schematic diagram showing an example of use of the television camera device.

In FIG. 4, reference numeral 11 denotes an IIL microscope, and binocular eyepiece barrel 12. It is equipped with a lens barrel 13 exclusively for the camera. Also,
14 is a camera controller, 15 is a monitor television, and 16 is a power supply circuit.

A camera head 18 is attached to the lens barrels 12 and 13 of the microscope 11 via a camera holder 17 as shown in FIGS.
is now installed.

In this embodiment, the camera radar 18 is a CCD (Cha
rge Coupled Device) The imaging section is composed of a solid-state imaging device, and the housing 19 is equipped with an aperture adjustment ring 20, a focus adjustment ring 21, and a focus lock ring 22 (see FIG. 1).

The camera holder 17 includes a pod part 23 and, for example, two types (or three or more types) of mount parts 24A and 24B that can be attached to and detached from the pod part 23. The camera head 18 is attached to the Pode part 23, and the Pode part 25A is
A window 23A is provided for holding the camera head 18 at 25B and allowing the rings 20, 21, and 22 to be operated. As shown in FIG. 2, the mount parts 24A and 24B are exchangeably joined to the pod part 23 and integrated into the pod part 23 with bolts 25C. The mount portion 24A includes a mounting hole portion 26A with a large diameter DI that matches the mounting size of the camera lens barrel 13, for example, and the mounting hole portion 2
6A is attached to the camera lens barrel 13 and locked with the bolt 25D (see Fig. 1 (A)), the mount part 24B
For example, the mounting hole 26B has a small diameter D2 that matches the mounting size of the eyepiece barrel 12, and the mounting hole 26B is attached to the outer diameter part of the eyepiece barrel 12, and the bolt 25E is attached to the mounting hole 26B. It is locked (see FIG. 1(B)).

Next, the operation of the above ff1l embodiment will be explained.

According to the first embodiment, the camera head 18 is connected to the microscope 1.
The camera holder 17 attached to the camera holder 1 can be attached to lens barrels of different mounting sizes, for example, the eyepiece lens barrel 12 and the camera lens barrel 13, by appropriately exchanging the mount parts 24A and 24B.
Can be attached to each.

Therefore, the camera head 18 can be attached not only to the camera lens barrel 13 but also to an eyepiece lens barrel 12 or the like having a different mounting size from the camera lens barrel 13.

It does not have a dedicated camera lens barrel 13! Video observation can also be made using an Il microscope. Further, since the camera head 18 can be attached to each lens barrel of a different attachment size, it can be used in combination with a plurality of microscopes 11.

FIG. 5 is a sectional view showing essential parts of a camera holder according to a second embodiment of the present invention.

The camera holder 31 does not have the mount parts 24A, 24Bt as in the camera holder 17, but has two types (there may be three or more types) of large-diameter mounting holes 33A and a small-diameter hole in the pod part 32. A hole attachment portion 33B is provided. Note that 32A is a window, and 25A, 25B, 25D, and 24E are bolts similar to those in the camera holder 17.

Even in this second embodiment, the camera holder 31 has a large diameter attachment hole 33A, for example, for a large diameter camera lens barrel 13.
, and a small diameter attachment hole 3 is attached to the small diameter eyepiece barrel 12.
By appropriately selecting and using the attachment holes 33A and 33B, for example, by attaching the eyepiece lens barrel 12 and the camera lens barrel 13, it is possible to attach the eyepiece lens barrel 12 and the camera lens barrel 13, respectively.

Note that the attachment means of the present invention can also be widely applied to television camera devices for other optical observation devices such as endoscopes.

Further, the attachment means of the present invention may be provided with a filter such as an optical IJJR filter in a fixed or detachable state.

Furthermore, the attachment means of the present invention may be integrally molded with the housing of the camera head.

[Effects of the Invention] As described above, according to the invention, video observation of objects to be observed can be popularized by easily connecting a camera to various optical observation devices.
