(57) [Summary] (Correction) [Purpose] This is to enable observation using a television camera with a microscope that is normally used for visual observation. [Structure] A light receiving surface D is formed inside a metal mount G having a circular cylindrical shape which is processed so as to be inserted into an eyepiece cylinder of a microscope.
A television camera head B having a structure in which an electronic circuit having a signal is taken out from the rear portion and a rubber packing J for holding the cable is attached, a camera control unit E for producing signals for controlling the same, and between them. The camera cable K for connecting

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to a microscope observation by a television camera, and relates to a device which allows a microscope to be easily and easily observed by a microscope which is normally used for visual observation. Is.

[0002]

[Prior art]

 For microscope observation using a conventional television camera, when using a television camera such as C mount and (ENG) lens mount method, which are standard lens mount methods for television cameras, a dedicated lens barrel for the television camera Since a microscope is used for observation, there is a drawback in that a dedicated lens barrel must be prepared to change from an ordinary observation state to an observation state using a television camera.

[0003]

[Problems to be solved by the device]

 As described in the prior art, there is a problem that a special lens barrel called a television lens barrel must be used in order to use a television camera for microscopic observation. Since it has a structure that does not work, it is troublesome to replace the lens barrel.

In order to solve this point, the eyepiece tube of the eyepiece part of the microscope is standardized in the present invention, and the structure is the same even if the manufacturer or model is different, and the compatibility is excellent. It is a device that can display an image just by replacing it with the eyepiece of interest.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, in the device of the present invention, a television set is so compact that a mount made of metal is inserted into the eyepiece tube so that the television camera can be directly inserted into the eyepiece tube. The camera head is positioned on the image plane in the eyepiece tube.

[0006]

[Embodiment of device]

 The television camera head configured as shown in FIG. 2 is inserted into the one-sided lens barrel of the eyepiece tube so that the microscope observation by the television camera can be performed without using any auxiliary equipment.

[0007]

【Example】

 In FIG. 3, A is an eyepiece tube of a microscope. A television camera in which an electronic circuit part is placed inside a mount G made by machining a metal such as aluminum into a circular tube so as to be mounted in the eyepiece tube. When the television camera head B forming the head B is attached to the eyepiece lens barrel A, the television camera head light receiving surface D of B is aligned with the focus position imaged in C of FIG. In this way, it is possible to perform microscopic observation with a television camera simply by inserting the B television camera head into the eyepiece tube of A without the need for any auxiliary equipment.

[0008]

[Effect of device]

 It is no longer necessary to use a television lens barrel to attach a television camera to the microscope, so that the microscope can be observed by a television camera by replacing it with the one-sided eyepiece lens of the binoculars barrel for visual observation that is normally used. Become.
