Abstract

PURPOSE:To eliminate the need for shutter opening operation and to facilitate the handling by providing a detecting means which detects a television camera being mounted and a control means which opens the shutter of a silver-plate camera with the signal of the detecting means. CONSTITUTION:A photographing means 7 for a silver-plate film which is incorporated to an endoscope is provided with the shutter 8 for the photography of the silver-plate camera and the opening/closing control circuit 9 which controls its opening and closure. When the television camera 5 is mounted on this endoscope, and adapter 11 is mounted on the photographing means 7, then a 1st contact 10 and a 2nd contact 12 are connected electrically to each other to control the shutter 8 into the open state. Therefore, the shutter need not be opened unlike before each time the television camera is mounted to make the handling extremely easy.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a photographing device for a microscope, which enables magnified photographing of a sample on a microscope using a silver halide film camera, a television camera, or the like.

[Prior art and problems to be solved by the invention] As a conventional photographing device for a microscope, for example, there is one shown in FIG. is attached, and a camera 3 for silver halide film is attached to this photographic means 2 for silver halide film. And a silver halide film camera 3 as a recording device.
When trying to use a television camera or the like instead of a camera, a shutter is not necessary since the television camera is a camera consisting of an image pickup tube or an image sensor such as a CCD. The photographic means 2 had to be removed, and the television camera adapter 4 and the television camera 5 had to be attached to the microscope 1 as shown in FIG. 6, which was complicated.

In addition, in a microscope with a built-in photographic means for silver halide film, the photographic means 2 for silver halide film cannot be removed, and only the camera 3 for silver halide film can be used for photographing silver halide film by means of attaching and detaching, for example, a bayonet mount type. It can be attached and detached from means 2. When replacing the silver halide film camera 3 with a television camera 5, the television camera 5 can be attached to the silver halide film photographic means 2 via a bayonet mount type adapter.

However, in this case, since the shutter of the silver halide film photographic means 2 is closed, the photographing light does not reach the television camera 5, and no photographing is possible. Therefore, there was a drawback that the shutter had to be opened by operating the photographic means 2 for silver halide film.

In view of these problems, the present invention provides a photographing device for a microscope in which a television camera is attached to a photographic means for silver halide film or a microscope having the same, and the shutter can be automatically opened at that time. The purpose is to provide

[Means to solve the problem]

The photographing device for a microscope according to the present invention allows a silver halide film camera and a television camera to be selectively attached to a microscope equipped with a silver halide film photographic means having a built-in shutter for exposure control. A photographing device for a microscope includes a detection means for detecting when a television camera is attached, and a control means for opening a shutter based on a detection signal from the detection means.

[For production]

When a silver halide film camera is attached, exposure control is performed by the shutter of the silver halide film photographic means, and when a television camera is attached, the shutter is in an open state.

〔Example〕

Hereinafter, a first embodiment of the present invention will be described based on FIGS. 1 and 2, and the same parts as those of the above-mentioned conventional device will be denoted by the same reference numerals, and the explanation thereof will be omitted.

In the figure, FIG. 1 shows a microscope that does not have a built-in photographic means for silver halide film, 7 is a photographic means for silver halide film attached to the microscope 1, and as shown in FIG. A shutter 8 for exposure control, which is operated when the camera 3 is used for photographing, and a shutter opening/closing control circuit 9, that is, a control means, for controlling the opening and closing of the shutter 8 are built in. Reference numeral 10 indicates a first contact which is provided in the photographic means 7 for silver halide film and is connected to the shutter opening/closing control circuit 9 and is provided with, for example, a plurality of terminals, and 11 is a first contact provided in the photographic means 7 for silver halide film. It is an adapter for attaching to the photographic means 7 for silver halide film, for example, by a bayonet mount method. 12
is a second contact which is provided on the adapter 11 and has a terminal corresponding to the first contact IO, and when the adapter 11 is attached to the photographic means 7 for silver halide film, both contacts 10°1
2 are electrically connected (for example, by short-circuiting two or more terminals of the second contact 12), the shutter 8 is controlled to be in an open state.

Since this embodiment is configured as described above, the microscope 1
When the silver halide film camera 3 is attached to the silver halide film photographic means 7 with the silver halide film photographic means 7 attached thereto, exposure control is performed by the shutter 8.

In place of the silver halide film camera 3, the adapter 11 to which the television camera 3 is attached is connected to the silver halide film photographic means 7.
When the first contact 10 and the second contact I2 are connected to each other, a detection signal is sent to the shutter opening/closing control circuit 9 by electrical conduction or non-conduction between the respective terminals, and the shutter 8 is opened.

Thereby, the image of the sample magnified by the microscope 1 can be photographed by the television camera 5.

As described above, according to this embodiment, the shutter 8 is automatically opened when the television camera 5 is attached, and complicated operations can be omitted.

FIG. 3 shows a second embodiment of the present invention relating to a microscope 14 with a built-in photographic means for silver halide film.
A pair of mounting members 1 with the TV camera adapter 11 of 4
4a, a first contact 10 is arranged so as to be able to connect with the second contact I2 during installation.

Incidentally, the first contact lO and the second contact 12 constitute the detection means, but the first contact 10 and the second contact 12 constitute the detection means.
0.12, a photosensor 16 and a light shielding member 17 may be employed (see FIG. 4 (al)), or a microswitch 18 and a microswitch driving member 19, etc. may be employed (see FIG. 4(b)). )reference).

In addition, if the television camera 5 is configured so that it can be attached directly to the photographic means 7 for silver halide film or the attachment part 14a, etc., without using the adapter 11, the detection of the second contact 12, etc. to the television camera 5 is possible. Needless to say, all you have to do is arrange the means.

〔Effect of the invention〕

As described above, the microscope imaging device according to the present invention is equipped with a detection means for detecting when a television camera is attached, and a control means for opening the shutter.
This has an important practical advantage in that when a television camera is installed in place of a silver halide film camera, there is no need to operate the shutter to open the shutter, making it easier to handle.
