has many features such as: That is, it is determined which camera optical path is selected based on the signal from the first camera optical path detection switch 20 or the second camera optical path detection switch 21, and the photographing information corresponding to the selected camera optical path is read out from the storage circuit. The display drive/information input circuit 26
function to send new photographic information input from the photographic information input section 25 to the display section drive/information input circuit 26.
Function to read into the memory circuit via the photometry circuit 22
A function to determine the exposure time in response to signals from the camera, and control signals for opening and closing the shutter 16 and winding the film of the first camera 18 and the second camera 19.
This function includes sending the data to the shutter/camera drive circuit 23.

FIG. 3 is a perspective view showing the external appearance of a photography microscope having the optical system shown in FIG. The imaging information display section 24 and the imaging information input section 25 are integrally provided on the input operation panel 31 at the front of the microscope main body 28.

FIG. 4 is an enlarged view of the input operation panel 31.
As shown in the figure, the photographing information display section 24 displays camera optical paths (camera 1, camera 2),
It is designed to display the number of film frames (FRAME), film sensitivity (ASA), reciprocity law failure value (RECIP.), exposure adjustment value (EXP.ADJ.), and exposure time (EXP.T). Further, the photographing information input section 25 includes a film information input switch 29 for changing the film sensitivity and reciprocity failure value, and an instruction for instructing whether or not the film information displayed on the photographing information display section 24 should be stored. A film information set switch 30 is provided for this purpose. Shooting information display section 2
The display contents of 4 and the information input switch 29 of the photographing information input section 25 are arranged in correspondence with each other.
You can accurately update shooting information and perform correction operations while checking the displayed content.

5 and 6 are flowcharts showing an internal processing method by the control circuit 27. FIG. The operation of the photography microscope of the present invention will be further explained using this flowchart. For example, if the optical path switching prism 17 is in the position shown in FIG. The corresponding photographing information is read from the storage circuit and sent to the display drive/information input circuit 26, so the photographing information display section 24 displays the photographing information of the first camera 18 and is used to determine the exposure time. . Furthermore, if the optical path switching prism 17 is located at a position rotated 90 degrees to the right from the position shown in FIG.
It detects that the second camera 19 has been selected by the signal from
, so the shooting information display section 24 displays the second camera 1.
9 is displayed and used to determine the exposure time. The photographing information of the first camera 18 and the second camera 19 is stored in the storage circuit of the control circuit 27 even when the power is off. Therefore, turn the power back on
Even after it is turned on, the previous shooting information will be displayed on the shooting information display section 2 for each selected camera optical path.
4 will be displayed. In this way, the shooting information only needs to be set once for the first time.

The photographing information is updated or corrected by operating the film information input switch 29. As shown in the flowchart of FIG. 6, the control circuit 27 operates the display section drive/information input circuit 26 in accordance with the film information input switch 29, so that the photographing information display section 2
The display of film information in step 4 is changed and the display is made to blink. Next, when it is determined that this new film information should be stored, the film information set switch 30 is pressed. Then, the control circuit 27 reads the new film information as photographing information into the storage circuit via the display section driving/information input circuit 26 and stores it in the storage circuit, and causes the photographing information display section 24 to display the new film information. lights up continuously.

If it is determined that new film information should not be stored, the film information set switch 30 is not pressed and is left as is. Then, after 10 seconds have elapsed since the film information input switch 29 was pressed, the control circuit 27 again reads out the photographing information from the memory circuit before the switch 29 was pressed, and stores it in the display drive/information input circuit 26. Since the photographing information is sent, the photographing information is displayed again on the photographing information display section 24, and the display is lit continuously.
In this way, the setting contents of shooting information can be easily updated or corrected, and when inputting new shooting information, it is possible to instruct whether or not to memorize it, so it is possible to prevent erroneous input, and as a result , it becomes possible to accurately change the setting contents of photographing information.

Note that although the above embodiment shows a case where there are two cameras, the present invention is not limited to this, and it goes without saying that it can be applied to a photography microscope having three or more cameras. .

As described above, the photographic microscope according to the present invention requires setting of photographing information only once for the first time, and the setting contents can be easily and accurately updated or corrected as necessary, thereby eliminating the troubles associated with conventional use. Eliminate the problem.
