Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an imaging device for a microscope, which is capable of enlarging and photographing a sample on a microscope with a camera for a silver halide film, a television camera, or the like.

[Prior Art and Problems to be Solved by the Invention] As a conventional photographing apparatus for a microscope, for example, there is one shown in FIG. 5, and a photographing means 2 for a silver halide film in which a microscope 1 has a built-in shutter for exposure control. A silver halide film camera 3 is mounted on the silver halide film photographing means 2. When a television camera or the like is to be used instead of the silver halide film camera 3 as a recording device, a shutter is not necessary because the television camera is a camera including an imaging device such as an imaging tube or a CCD. The camera 3 for the silver halide film and the photographing means 2 for the silver halide film must be removed, and the television camera adapter 4 and the television camera 5 must be attached to the microscope 1 as shown in FIG.

Further, with a microscope incorporating a photographic means for a silver halide film, the photographic means 2 for a silver halide film cannot be detached, and only the camera 3 for a silver halide film can be used, for example, by a bayonet mount type attaching / detaching means. It can be detached from the means 2. When the silver halide film camera 3 is replaced with the television camera 5, the television camera 5 can be attached to the silver halide film photographing means 2 via a bayonet mount type adapter.

However, in this case, since the shutter of the photographic means 2 for a silver halide film is closed, the photographing light does not reach the television camera 5 and photographing cannot be performed. Therefore, there is a disadvantage that the shutter has to be opened by operating the photographic means 2 for a silver halide film.

SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a photographing apparatus for a microscope in which a television camera is mounted on a photographic means for a silver halide film or a microscope having the same, and at that time, a shutter can be automatically opened. The purpose is to provide.

[Means for solving the problem]

The photographing apparatus for a microscope according to the present invention allows a camera for a silver halide film and a television camera to be selectively mounted on a microscope to which a photographing means for a silver halide film having a built-in exposure control shutter is attached. 2. Description of the Related Art A photographing apparatus for a microscope includes a detecting unit for detecting when a television camera is mounted, and a control unit for opening a shutter based on a detection signal of the detecting unit.

[Action]

When the camera for silver halide film is mounted, exposure control is performed by the shutter of the photographic means for silver halide film, and when the television camera is mounted, the shutter is opened.

〔Example〕

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 and 2, but the same parts as those of the above-described conventional device will be denoted by the same reference numerals and description thereof will be omitted.

In the drawing, FIG. 1 shows a microscope which does not have a built-in photographic means for a silver halide film, and 7 shows a photographic means for a silver halide film attached to a microscope 1. As shown in FIG. A shutter 8 for controlling exposure, which is operated at the time of photographing by the camera 3, and a shutter opening / closing control circuit 9 for controlling the opening / closing of the shutter 8, that is, a control means, are built in. Reference numeral 10 denotes a first contact provided on the silver halide film photographic means 7 and connected to, for example, a plurality of terminals connected to the shutter opening / closing control circuit 9, and 11 denotes a television camera 5 connected to the silver halide film photographic means 7. An adapter for attaching to the silver halide film photographing means 7 by, for example, a bayonet mount method. Reference numeral 12 denotes a second contact provided on the adapter 11 and provided with a terminal corresponding to the first contact 10. When the adapter 11 is mounted on the photographic means 7 for a silver halide film, both contacts 10, 12 are electrically connected. (For example, two or more terminals of the second contact 12 are short-circuited), and the shutter 8 is controlled to be open.

Since the present embodiment is configured as described above, when the silver halide film photographing means 7 is attached to the microscope 1 and the silver halide film camera 3 is attached to the photographing means 7, Exposure control is performed by the shutter 8.

Then, instead 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 photographing means 7.
When mounted on, the first contact 10 and the second contact 12 are connected,
A detection signal is sent to the shutter opening / closing control circuit 9 based on the electrical conduction and non-conduction between the terminals, and the shutter 8 is opened.

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

As described above, according to the present embodiment, the shutter 8 is automatically opened when the television camera 5 is mounted, and a complicated operation 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 a silver halide film.
A pair of mounting members 14a with the TV camera adapter 11
In addition, the first contact 10 can be connected to the second contact 12 during mounting.
Are arranged.

Incidentally, the first contact 10 and the second contact 12 constitute a detecting means, but as the detecting means, the first and second contacts 10, 1
A photo sensor 16 and a light shielding member 17 may be used instead of the micro switch 18 (see FIG. 4A).
Alternatively, a micro switch driving member 19 or the like may be employed (see FIG. 13B).

When the television camera 5 is configured to be directly mounted on the silver halide film photographing means 7 or the mounting portion 14a without passing through the adapter 11, the television camera 5 can detect the second contact 12 or the like. Needless to say, means must be provided.

〔The invention's effect〕

According to the photographing apparatus for a microscope according to the present invention as described above,
Since the detection means for detecting this when the TV camera is mounted and the control means for opening the shutter are provided, the shutter opening operation is not required when the TV camera is mounted in place of the silver halide film camera, It has an important practical advantage that it is easy to handle.
