Abstract

PURPOSE:To set photographic information only once at the beginning and to vary set contents easily when necessary by reading photographic information corresponding to the detected optical path of a camera out of a storage means. CONSTITUTION:A control circuit 27 consisting of a storage circuit, microcomputer, etc., has many functions, namely, reads the photographic information corresponding to the camera optical path by signals from optical path detection switches 20 and 21 of cameras 18 and 19 to send it to a display part driving and information input circuit 26, reads photographic information from a photographic information input part 25 in the storage circuit, and determines an exposure time from a light metering circuit 22. Thus, the photographic information of the cameras 18 and 19 are stored in the storage circuit of the control circuit 27 even in a power-off state, so the photographic information before the power source is turned on is selected even after the power source is turned on and displayed on a display part 20 corresponding to each camera optical path. Therefore, the photographic information is set only once in the beginning.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a photographic information input storage and display device for a photographic microscope having a plurality of cameras.

With conventional photography microscopes of this type, when taking pictures using different types of film for each camera, the sensitivity settings are set to match the film of the camera being used, but the sensitivity settings must be re-set each time the camera is changed. There was the annoyance of not having to do so.

In view of the above-mentioned problems, the present invention provides a detection means for detecting the optical path of a camera for photographing, a storage means for storing photographing information of a plurality of cameras, and an input for inputting new photographing information and instructing whether or not to store it. means, reading/loading means for reading photographic information corresponding to the camera optical path detected by the detecting means from the storage means and reading new photographic information from the input means into the storage means;

[Due to this, the setting of shooting information such as film sensitivity only needs to be done once for the first time, and the settings can be easily and accurately changed as necessary. This is an attempt to provide a photographing information input storage display device that eliminates the above-mentioned troubles by obtaining the above information, but this will not be explained based on the example shown below. The optical system of the photographic microscope is shown in which 1 is a light source, 2 is a condenser lens, 3 is a field stop, 4 is a relay lens, 5 is a reflector, 6 is an aperture stop, and 7

15 is a photoelectric conversion element, 16 is a shank, 17 is an optical path switching prism that is rotated by a signal from a camera selection switch (not shown), 18 is a first camera, and 19 is a second camera. .

FIG. 2 shows a block diagram of the circuit of this embodiment. 5.20 (denoted as the first camera optical path detection switch, 2I as the second camera optical path detection switch, 22 as the photometry circuit, and 23 as the shutter camera). 24 is a display section for displaying photographing information such as film information; 25 is a photographing information input section used for inputting new photographing information when changing photographing information; 26 is a driving circuit;
27 is a display drive/information input circuit, and 27 is a power ON/OFF circuit.
The control circuit 27 is a control circuit consisting of a memory circuit capable of retaining memory regardless of F and a microcomputer, etc.
determines 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, reads out the photographing information corresponding to the camera optical path from the storage circuit, and drives the display section. sending the new image information inputted from the photographing information input section 25 to the information input circuit 26; The shutter/camera 1 drive circuit 23 sends control signals for determining the exposure time, opening/closing the shutter 16, and winding the film of the first camera 18 and second camera 19.
It has many functions such as sending to. Figure 3 is the first

located on the front panel of the Figure 4 is an enlarged view of the front panel, as shown in the display section 2.
0 displays the camera optical path, number of film frames, film sensitivity, reciprocity failure value, exposure adjustment value, and exposure time as photographic information. The darkest information input section 21 also includes a film information input switch 29 for changing the film sensitivity and reciprocity law failure value, and a film information input switch 29 for instructing whether or not the film information displayed on the display section 20 should be stored. A film information set switch 30 is provided.

Since the human power storage and display device in the photographic microscope according to the present invention is constructed as a series, for example, if the optical path cutting prism 17 is located at 1a° as shown in FIG. , the control 11 circuit 27 detects that the first camera 18 is selected by the signal from the first camera optical path detection switch 20, as shown in the flowchart of FIG.
The corresponding photographic image is read out from the memory circuit and sent to the display unit 1 drive/information input circuit 26.
4 of the first camera I8. A shadow information is displayed and used to determine 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. The second camera 19's shooting information is displayed on the display section 24 and is used to determine the exposure time. be done. Furthermore, since the photographing information of each camera 1'8, 19 is stored in the storage circuit of the control circuit 27 even when the power is turned off, the previous photographing information will remain in the optical path of each selected camera even after the power is turned on again. is displayed on the display unit 20 in response to the above. Therefore, the shooting information only needs to be set once at the beginning.

Further, when changing photographing information, the film information etc. are first changed using the film information input switch 29.

Then, as shown in the flowchart of FIG.
change the display of film information in and make the display blink. Next, it is determined that this new film information should be stored, and the information set switch 30 is pressed.Then, the control circuit 27 controls the display section drive and
New film information is read into the storage circuit as hourglass information through the information input circuit 26 and stored therein, and the display is displayed on the display section 24, and the display is lit continuously. If you decide that you should not write new film information, use the film information set switch 3.
Do not press 0 and leave 15 alone. Then, control circuit 2
7 (l-1: After 10 seconds have passed since the film information input switch 29 was pressed, the photographing information before the switch 29 was pressed is read out from the memory circuit and the display unit is driven.
Since the information is sent to the information input circuit 26, the photographing information is displayed again on the display section 24, and the display is lit continuously. In this way, it is possible to easily change the shooting information settings, or
Notes on entering shooting information: 1. Since it is possible to instruct whether or not to perform φ'', it is possible to prevent erroneous input, and as a result, it is possible to accurately change the settings of the photographing information.

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

As described above, according to the photographing information input storage/display device for a photographic microscope according to the present invention, the photographing information needs to be set only once at the beginning, and the setting contents can be easily and accurately changed as necessary. It has an important practical advantage of eliminating the troubles of the conventional method.
