EXAMPLES Examples of the present invention will be described below.

FIG. 1 shows a schematic functional block of a microscope image taking apparatus according to an embodiment of the present invention. Note that the configuration of the optical system of the present embodiment is the same as that shown in FIG. 4 described above, and therefore different parts will be described in detail here.

The camera detector 2 is attached to each of the camera mounts 10 to 12 having a structure capable of mounting a predetermined camera device.
1 to 23 are provided respectively. These camera detectors 21 to 23 can detect the presence and type of the camera device mounted on their own camera mounts 10 to 12.

A mode selection switch 24 is provided for accepting selection of "silver film camera mode" for shooting with a silver film camera device or "TV camera mode" for shooting with a TV camera device. Since the selection of "camera mode for silver salt film" means the use of the camera for silver salt film and the selection of "TV camera mode" means the use of the TV camera device, this mode selection switch 24 serves as the camera selection means. It has the function of. The mount selection switch 25 selects which of the three camera mounts 10 to 12 is to be used. Reference numeral 26 indicates a shutter manual button, which is used when manually operating the shutter. The mode selection switch 24, mount selection switch 25, and shutter manual button 2
6 are connected to the CPU 27, respectively.

The CPU 27 reads the mode selection input, the camera mount selection input, and the camera detection signal, and controls the operation of the motor 9 and the shutter 7 of the camera selection prism 8 according to the flowchart shown in FIG. Next, the operation of this embodiment will be described with reference to FIG.

By receiving the mode selection signal from the mode selection switch 24, the processing unique to this embodiment regarding the operation control of the motor 9 or the shutter 7 is started.
When the "silver-salt film camera mode" is selected, the exposure correction value, I
The SO value and the like are set. Here, it is assumed that the "silver-salt film camera mode" is selected.

Next, a camera mount selection input is received from the mount selection switch 25, and the presence / absence and type of the camera device indicated by the camera detection signal from the camera mount designated by the selection input is determined. If the camera device is mounted on the camera mount designated by the selection input and the type is a silver salt film camera device, the rotation operation of the camera selection prism 8 is permitted.

If no camera device is mounted on the selected camera mount or a camera device other than the silver halide film camera device is mounted, a new selection input is awaited. This process prevents the photographer's erroneous operation.

Next, the CPU 27 controls the motor 9 to rotate the camera selection prism 8 to reflect the subject light from the objective lens 3 to the camera mount side where the silver salt film camera device is mounted.

Next, when the exposure mode is determined by accepting the exposure mode from the exposure mode setting switch (not shown),
The shutter is opened and exposure processing is performed based on the determined exposure method.

On the other hand, the "T"
When the "V camera mode" is selected, the camera mount selection input is awaited in the same manner as described above, and the presence or absence and the type of the camera device indicated by the camera detection signal from the camera mount designated by the selection input is determined. As a result, if it is recognized that the TV camera device is mounted on the selected camera mount, the rotation operation of the camera selection prism 8 is permitted.

Here, if the photographer mistakenly takes a picture in the "TV camera mode" but selects a camera mount on which the silver salt film camera device is mounted, the camera is selected by the above processing. The rotation operation of the prism 8 is limited. Therefore, it is possible to prevent the silver salt film from being exposed due to an erroneous operation.

The CPU 27 controls the motor 9 to rotate the camera selection prism 8 to reflect the subject light from the objective lens 3 to the camera mount side on which the TV camera device is mounted.

In this way, when the optical path is switched to the TV camera device side by the camera selection prism 8, the shutter is not opened directly but the light amount is adjusted within the allowable range of the TV camera device. After this light amount adjustment, the shutter is opened and the subject image is captured on the image pickup surface of the TV camera device.

As described above, in this embodiment, when the photographing mode desired by the photographer is selected and input from the mode selection switch 24 and the camera mount corresponding to the selected photographing mode is selected and input from the camera mount selection switch 25, the camera is selected. By using the camera detection signals from the detection units 21 to 23,
It is checked whether or not the camera device desired by the photographer is mounted on the camera mount designated by the photographer, and the rotation operation of the camera selection prism 8 is restricted.

Therefore, when the photographer erroneously selects and inputs the camera mount irrelevant to the photographing mode, the rotation operation of the camera selection prism 8 is prohibited and the malfunction is surely prevented. In particular, even if the "TV camera mode" is selected, the silver salt film can be prevented from being exposed when the camera mount of the silver salt film camera device is mistakenly input, which is economical.

Further, according to the present embodiment, when the image is taken by the TV camera, the light amount is adjusted before opening the shutter 7 and the incident illuminance is suppressed within the allowable range of the image pickup device of the TV camera, and then the shutter 7 is opened. Since it is set to open, it is possible to prevent the image pickup device of the TV camera from being destroyed. In particular, this effect is exhibited when a high-sensitivity TV camera device is used as the TV camera device.

In the above embodiment, both the selection input from the mode selection switch 24 and the selection input from the mount selection switch 25 are taken in to judge whether the photographing camera is a TV camera or not. Switch 2
The same function can be realized by either one of the selection input from 4 and the selection input from the mount selection switch 25. FIG. 3 shows a modification of the above embodiment.

This modification is an example in which the shutter control similar to that in the above-described embodiment is realized without selecting the camera mode.
That is, when the camera mount selection input is accepted,
The camera device mounted on the camera mount corresponding to the selection input is determined from the camera detection signal. As a result, if the TV camera device is mounted, it is determined whether the light amount adjustment is necessary before opening the shutter 7. When it is necessary to adjust the light amount because the high-sensitivity TV camera is attached, the light amount is adjusted and then the shutter is opened. If it is not necessary to adjust the light intensity, leave it open.

When it is detected from the camera detection signal that the camera mount is not mounted on the camera mount corresponding to the selection input, a display indicating that the device is not mounted is displayed. With this modification as described above, it is possible to prevent damage to the image pickup device of the TV camera device, particularly the high-sensitivity TV camera. The present invention is not limited to the above embodiments, and various modifications can be made without departing from the gist of the present invention.
