この発明はテレビカメラの撮像管の撮像面を保
護するようにした内視鏡用テレビカメラ装置に関
する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an endoscope television camera device that protects the imaging surface of an image pickup tube of a television camera.
内視鏡で体腔内を観察する場合、上記内視鏡の
接眼部にテレビカメラを接続し、観察像をテレビ
モニタに写し出すようにすることが行なわれてい

まにしておくと、上記撮像面の電荷が大きくな
り、撮像面が焼き付けを起こして画質が著しく低
下してしまうので、上記撮像面を外部の光から保
護しなければならない。 When observing the inside of a body cavity using an endoscope, a television camera is connected to the eyepiece of the endoscope so that an observed image is displayed on a television monitor. By the way, when the television camera is removed from the eyepiece after observation, if light from the outside is allowed to enter the imaging surface of the imaging tube of the television camera, the charge on the imaging surface will increase. The image pickup surface becomes large, causing burn-in on the image pickup surface and significantly lowering the image quality, so the image pickup surface must be protected from external light.
従来、テレビカメラの撮像面を外部光から保護
するには、テレビカメラの接眼部から外したとき
に、このテレビカメラの入光部に設けた絞りを手
動で閉めたり、上記入光部に自動絞り装置を設
け、テレビカメラの電源を切つたときに自動的に
絞りが閉じるようにするなどして、上記撮像面に
外部の光が入射するのを防止していた。 Conventionally, in order to protect the imaging surface of a television camera from external light, when the television camera is removed from the eyepiece, the aperture provided at the light input section of the television camera must be manually closed, or the light input section of the television camera must be closed manually. An automatic diaphragm device was installed so that the diaphragm automatically closed when the television camera was turned off, thereby preventing external light from entering the imaging surface.
しかしながら、手動で絞りを閉めるようにする
と、この操作が煩わしいばかりか、閉めるのを忘
れてしまうことがあり、確実性に乏しい。また、
自動絞り装置によれば手動のように閉め忘れると

いから、テレビカメラ全体が大形化および高重量
化してしまう。とくに光学機器が内視鏡の場合に
は、テレビカメラが大形化および高重量化する
と、このテレビカメラを支えながら術者が内視鏡
を操作しなければならないから、操作性が低下し
てしまう。 However, if the diaphragm is closed manually, this operation is not only troublesome, but there are also cases where the user forgets to close the diaphragm, resulting in a lack of reliability. Also,
With an automatic aperture device, you won't forget to close it like you would with a manual aperture device, but it requires a drive device and control circuit to drive the aperture to be built into the TV camera, making the entire TV camera larger and heavier. . Particularly when the optical device is an endoscope, as the TV camera becomes larger and heavier, the operator has to operate the endoscope while supporting the TV camera, which reduces operability. Put it away.
この発明は上記事情にもとずきなされたもの
で、その目的とするところは、テレビカメラの大

る。 This invention was made based on the above circumstances, and its purpose is to prevent the TV camera from becoming larger or heavier, and to synchronize the operation of attaching and detaching the endoscope to the TV camera. This TV camera for endoscopes uses a simple mechanism to prevent external light from entering the imaging surface of the TV camera's imaging tube when the endoscope is removed from the TV camera. The goal is to provide equipment.

面に開放して形成されている。 A shutter plate 25 is provided in the space 16 as an opening/closing mechanism for opening and closing one end of the connection hole 17 facing the space 16 . That is, the shutter plate 25 has one radial end rotatably supported by a hinge 26 on one end surface of the space 16 on the connection hole 17 side, and is supported by a spring 27 held by the hinge 26 to allow the shutter plate 25 to rotate freely. It is urged to close one end opening of the connection hole 17. Furthermore, an inner tube 28 whose inner diameter is slightly larger than the outer diameter of the eyepiece 5 is fitted and fixed into the connection hole 17, and the inner tube 28 has an eyepiece as shown in FIG. A substantially L-shaped engagement groove 30, into which a pin 29 protruding from the outer peripheral surface of the inner tube 5 engages, is formed with one end open at the distal end surface of the inner tube 28.

る。 According to the connecting device 6 having such a configuration, when the endoscope 1 is removed from the connecting device 6, the shutter plate 25 pivotally supported in the space 16 is attached to the spring 27 as shown in FIG. Power connection hole 17
Since the connection hole 17 is closed, no light from the outside enters the image pickup tube 13 of the television camera 7. In order to connect the endoscope 1 to the connecting device 6, the pin 29 protruding from the eyepiece 5 is aligned with the engagement hole 30 of the inner tube 28, and the eyepiece 5 is inserted into the connection hole 17. As shown in FIG. 3, since the shutter plate 25 is pushed up by the eyepiece 5 against the biasing force of the spring 27, the eyepiece 5 protruding into the space 16 and the imaging tube 13 are optically connected. be done. Once the eyepiece 5 is inserted to a predetermined position, turning the eyepiece 5 in the circumferential direction will position the pin 29 at the end of the engagement groove 30 and fix the eyepiece 5 to the connecting device 6. .
また、接続装置６に接続した接眼部５を接続時
と逆の手順で取り外すと、接眼部５によつて押し
上げられていたシヤツタ板２５がばね２７の復元
力によつて再び第２図に示すように接続孔１７を
閉塞する状態に戻る。 Furthermore, when the eyepiece 5 connected to the connecting device 6 is removed in the reverse order of the connection, the shutter plate 25, which had been pushed up by the eyepiece 5, is reactivated by the restoring force of the spring 27 as shown in FIG. The state returns to the state in which the connection hole 17 is closed as shown in FIG.
すなわち、シヤツタ板２５は接眼部５を接続孔
１７に挿脱する動作に応じてこの接続孔１７を開
閉するから、接続孔１７から接眼部５を取り外す
という操作だけでテレビカメラ７の撮像管１３に
外部の光が入射するのを防ぐことができる。 That is, since the shutter plate 25 opens and closes the connection hole 17 according to the operation of inserting and removing the eyepiece 5 into and from the connection hole 17, the image capturing of the television camera 7 can be performed simply by removing the eyepiece 5 from the connection hole 17. External light can be prevented from entering the tube 13.

た。 5 and 6 show a second embodiment of this invention,
In this embodiment, the shutter plate 25 is divided into two parts, and each shutter plate 25, 25 is pivotally connected by hinges 26, 26, respectively, and springs 27,
It was energized at 27. In addition, a pair of shutter plates 25,
25, these shutter plates 2 are attached to their free ends.
Stepped portions 31, 31 are formed which can polymerize when 5, 25 are closed and reliably block external light.

きる。 According to this configuration, the pair of shutter plates 25, 25 open and close the connection hole 17 in conjunction with the operation of inserting and removing the eyepiece 5 into and out of the connection hole 17, as in the first embodiment. Since the rotation radius of the plates 25, 25 is approximately half that of the shutter plate 25 of the first embodiment, the axial dimension of the space 16 can be reduced by that amount. That is, the main body 15 of the connecting device 6 can be made smaller.

部３５，３５を設けた。 Figures 7 and 8 show a third embodiment of this invention,
In this embodiment, the shutter plate 25 is divided into two parts as in the second embodiment, but the shutter plates 25, 25 are not directly pivoted to the main body 15 and can be opened and closed. That is, a pair of connecting members 32, 32 are pivotally attached to the main body 15 at their proximal ends by shafts 33, 33, and the connecting members 32, 32 are attached to the shafts 33, 33.
The shutter plates 25, 2 are attached to the free ends of the connecting members 32, 32 while holding the springs 34, 34 that bias the free end sides of the connecting members 32, 32 in the axial direction of the main body 15.
5 is pivotally connected by hinges 26, 26, and springs 27, 27 are provided at the hinges 26, 26.
Then connect the shutter plates 25, 25 to the connecting members 32, 3.
2, that is, when the eyepiece 5 is not inserted into the connection hole 17 as shown in FIG. was held in a closed state. Furthermore, protrusions 35, 35 are provided at the proximal ends of the connecting members 32, 32, which protrude inward in the radial direction of the connection hole 17 when the pair of shutter plates 25, 25 are closed.
