When a main switch (not shown) is turned on, the microcomputer 1 starts its operation from step 101.

In step 101, it is judged whether or not the exposure mode switch 12 is ON. If it is ON, the process proceeds to step 102, and if it is not ON, step 1
Proceed to 07.

At step 102, since the exposure mode switch 12 is in the ON state, the dial 13
Is rotated, and if the dial 13 is rotated, the process proceeds to step 103. If not rotated, the process proceeds to step 107.

In step 103, since the dial 13 is rotated while the exposure mode switch 12 is turned on, the exposure mode is changed in accordance with the rotation amount and the step 1
Go to 04. Then, in step 104, the RAM
If the flag in 7 is discriminated and it is in the series scene mode (indicated as SS mode in FIG. 2), step 1
Go to step 05 and go to step 107 if not in the series scene mode.

In step 105, since the exposure mode has been changed, the flag in the RAM 7 is released from the series scene mode and the series scene continuation flag is cleared. Then, in the next step 106, the display of the "series scene" displayed on the display unit 6 is erased, and a display warning that the series scene mode is automatically released is displayed. Here, the display section 6 is displayed to warn that the series scene mode has been released, but it is also possible to use an acoustic warning means such as a warning by a buzzer.

At the next step 107, the switch SS_SW (series scene setting switch 11) is turned on.
If it is ON, it is judged whether it is step 1
Proceed to 08, and if not ON, proceed to step 113.

In step 108, the flag in the RAM 7 is discriminated, and if it is not in the series scene mode, the process proceeds to step 109. And this step 10
In 9, the flag of the RAM 7 is set to the series scene mode to set the series scene mode. In the next step 110, the fact that it is a “series scene” is displayed on the display unit 6 and the process proceeds to step 113.

If it is a series scene in step 108, the process proceeds to step 111, where the flag in the RAM 7 is released from the series scene mode. Then, in step 112, the display of the series scene displayed on the display unit 6 is erased and the process proceeds to step 113.

Up to this point, if the exposure mode is changed while the series scene mode is set, the set series scene mode is automatically released, a warning is given, and the switch SS_SW is operated again. , Series scene mode can be set. In addition, when the switch SS_SW is turned on when not in the normal series scene mode, the "series scene mode" is set. When the switch SS_SW is turned on in the series scene mode, the "series scene mode" is released. By operating the switch SS_SW11, the series The scene is set and released.

Next, in step 113, it is judged whether or not the switch SW1 is turned on. If not, the process returns to step 101 to detect the state of the switch SS_SW and wait for the switch SW1 to be turned on. .

On the other hand, if the switch SW1 is ON, step 1 is started to start photometry and distance measurement from step 113.
14, the light amount is measured by the light metering circuit 2 to determine the proper exposure value, the light amount of the object is measured to determine the exposure amount, and then the aperture value and the shutter speed are determined and step 1
Proceed to 15. Then, in step 115, distance measurement is performed by the distance measuring circuit 3, the lens (not shown) is operated to focus on the subject, and the process proceeds to step 116.

In step 116, the switch SW
It is determined whether or not 2 is ON, and if not ON, the process returns to step 101. On the other hand, if it is ON, the process proceeds to step 117 to perform the exposure operation, first the aperture control circuit 5 is operated to reduce the aperture of the lens to the value determined in step 114, and then the shutter control circuit 4 is operated. The shutter is controlled at the shutter speed determined in step 114 to perform the exposure operation, and then the aperture control circuit 5 is operated to return the aperture to the open state to end the exposure operation, and the process proceeds to step 118.

In step 118, the film feeding motor 17 is operated to start the film winding operation, and in the next step 119, the magnetic recording circuit 14 is operated to cause the magnetic head 15 to operate the film 1.
Recording of shooting data such as date is started in the magnetic storage unit 8 and the process proceeds to step 120.

At step 120, the series scene mode flag in the RAM 7 is discriminated, and if it is not the series scene mode, the routine proceeds to step 121. Then, in step 121, since the series scene mode is not set, if the series scene continuation flag in the RAM 7 is set, it is cleared and the routine proceeds to step 124.

If the series scene mode is selected in step 120, the process proceeds to step 122 and the RAM
It is determined whether or not the series scene continuation flag in 7 is set, and if it is not set, step 12
3, the series scene continuation flag in the RAM 7 is set here, and the routine proceeds to step 124.

In step 124, the series scene start signal is recorded on the magnetic recording layer of the film 18. This step is for when not in series scene mode,
It is set to the series scene mode and is executed when the first picture is taken.

If the series scene continuation flag is set in step 112, the process proceeds to step 125, where the series scene end signal is recorded in the magnetic recording portion of the film 18. This step is executed when the second and subsequent images are taken after the series scene mode is entered.

At the next step 126, all the magnetic recording data to be recorded is recorded on the film, and when this magnetic recording operation is completed, the routine proceeds to step 127. And
In step 127, when it is detected by the film detection circuit 14 and the photosensor 15 that the film 18 has reached the predetermined position where one frame has been fed, the film feeding circuit 16 stops the film feeding motor 17. Then, the release operation is completed and the process returns to step 101 to wait for the next release.

FIG. 3 is a diagram showing information relating to the series scenes recorded on the film when photographed in each of the series scene mode and the non-series scene mode, and this information is the magnetic recording of the film 20 as described above. Layer 2
It is recorded in 1.

The exposure of the film 20 is sequentially performed from the photographing frame 22 on the right side of this figure.

The first shooting frame 22 in this drawing is the case where the series scene mode is set and the first shooting is performed, and the start signal of the series scene is recorded here as described in the flowchart of FIG.

When the exposure mode is changed by operating the exposure mode setting switch 12 and the dial 13 after photographing the photographing frame 24 (for example, the aperture priority A from the program AE).
(Changed to E), series scene mode is automatically released. When the frame 25 is photographed in this state, the series scene mode is released due to the change of the exposure mode, resulting in a non-series scene. As described with reference to the flowchart of FIG. The signal to start the series scene is recorded.

After the photographing of the photographing frame 25 is completed, the switch SS_
When the series scene mode is set by operating the SW, the "series scene start signal" and the "series scene end signal" are recorded from the photographing frame 26 as in the case of the photographing frames 22 and 23.

When the film 20 photographed as described above is taken out to the developing place, the signal of the series scene recorded in the magnetic recording section 21 of the film 20 is read out when the printing is performed and the printing is performed. .

At this time, a series scene end signal is recorded in the shooting frame after the series scene start signal, and the frame is discriminated as a series scene while the series scene end signal is recorded, and the series scene is discriminated. A plurality of frames in a scene will be printed under the same conditions.

Here, a series scene is set only when there is a series scene end signal after the series scene start signal, and when the series scene mode is set and one frame is photographed and then the series scene mode is released, it is regarded as a series scene. It doesn't happen.

As described above, if the exposure mode is changed while the series scene mode is set, the series scene is automatically canceled and a warning is issued. Furthermore, if the photographer wants to set the series scene again, he can operate the switch SS_SW
It can be set as a series scene.

Although the exposure mode is switched by the switch and the dial here, a method of switching only by the switch or a method of switching by the line-of-sight input may be used. Also, the series scene mode setting can be switched by an input method other than the switch.

(Second Embodiment) FIG. 4 is a flowchart showing the operation of a magnetically recordable camera (microcomputer) according to the second embodiment of the present invention, which will be described below with reference to this flowchart. The circuit configuration of the camera is the same as that shown in FIG.

When the main switch (not shown) is turned on, the microcomputer 1 starts operation from step 201.

In step 201, the switch SS
Whether or not _SW11 is turned on is determined. If it is turned on, the process proceeds to step 202, and if not, the process proceeds to step 207.

In step 202, the flag in the RAM 7 is discriminated, and if it is not in the series scene mode, the process proceeds to step 203, in which the flag in the RAM 7 is set to the series scene mode and the series scene mode is set. Then, in the next step 204,
The fact that it is a "series scene" is displayed on the display unit 6 and the process proceeds to step 207.

If the series scene mode is selected in step 202, the flow advances to step 205 to release the flag in the RAM 7 from the series scene mode. Then, in the next step 206, the display of the "series scene" displayed on the display unit 6 is erased and the process proceeds to step 207.

Up to this point, when the switch SS_SW is turned on when not in the series scene mode, the "series scene mode" is set, and when the switch SS_SW is turned on in the series scene mode, the "series scene mode" is released and the switch SS_SW is operated. This makes it possible to set and cancel series scenes.

Next, in step 207, it is judged whether or not the switch SW1 is turned on. If not, the process returns to step 201 to detect the state of the switch SS_SW and wait for the switch SW1 to be turned on. .

After that, when the switch SW1 is turned on, the routine proceeds to step 208 to start photometry and distance measurement. Here, in order to determine an appropriate exposure value, photometry is performed by the photometry circuit 2 to measure the light quantity of the object. Then, the exposure amount is determined, the aperture value and the shutter speed are then determined, and the process proceeds to step 209.

In the next step 209, the distance is measured by the distance measuring circuit 3, the lens (not shown) is operated to focus on the object, and the process proceeds to step 210.

In the following step 210, it is determined whether or not the switch SW2 is ON, and if it is not ON, the process returns to step 201. On the other hand, if it is ON, the process proceeds to step 211 to perform the exposure operation, and the aperture control circuit 5 is first.
Is operated to reduce the aperture of the lens to the value determined in step 208 above, and then the shutter control circuit 4 is operated to control the shutter at the shutter speed determined in above step 208 to perform the exposure operation, and then the aperture control. Circuit 5
Is operated to return the aperture to the open state to end the exposure operation, and the process proceeds to step 212.

At step 212, the film feeding motor 17 is operated to start the film winding operation. At next step 213, the magnetic recording circuit 14 is operated to cause the magnetic head 15 to rotate the film 18.
The recording of the shooting data such as the date is started in the magnetic recording unit of No. 1 and the process proceeds to Step 214.

In the next step 214, the RAM 7
If the series scene mode flag in the RAM 7 is not the series scene mode, the process proceeds to step 215. Since there is no series scene mode here, if the series scene continuation flag in the RAM 7 is set, it is cleared and the process proceeds to step 218.

If the series scene mode is set in step 214, the process proceeds to step 216, where it is determined whether or not the series scene continuation flag in the RAM 7 is set. If not, the process proceeds to step 217 to RAM 7 The series scene continuation flag therein is set and the process proceeds to step 218.

In step 218, the series scene start signal is recorded in the magnetic recording portion of the film 18. This step is for when not in series scene mode,
It is set to the series scene mode and is executed when the first picture is taken.

If the series scene continuation flag is set in step 216, step 21
In step 9, the series scene end signal is recorded in the magnetic recording portion of the film 18. This step is executed when the second and subsequent images are taken after the series scene mode is entered.

In the next step 220, all the magnetic recording data to be recorded is recorded on the film, and then this magnetic recording operation is ended. And the next step 22
1, the film detection circuit 14 and the photo sensor 15
When it is detected that the film 18 has reached the predetermined position where the film has been fed by one frame, the film feeding circuit 16 stops the film feeding motor 17 and increments the value of the film counter in the RAM 7 by one. At the same time, the display on the film counter of the display unit 6 is also incremented by 1 and step 222
move on.

In step 222, it is judged whether or not the film counter of the RAM 7 reaches the number of frames detected by the filmable frame number detecting means (not shown) and the film is finished, and the film is finished. If not, the process returns to step 201 and waits for the next release.

If it is determined in step 222 that the film has ended, the process proceeds to step 223, the series scene mode flag in the RAM 7 is released from the series scene mode, and the series scene continuation flag is cleared. Then, in the next step 224, the display of the "series scene" displayed on the display unit 6 is erased and the process returns to step 201 to end the release operation. Here, the fact that the series scene has been automatically canceled may be displayed on the display unit, or a buzzer or the like may be used to warn the photographer.

As described above, when the film is finished in the series scene mode, the series scene is automatically released.

Further, although the series scene mode is automatically canceled at the end of the film here, the series scene may be canceled when the film is taken out or loaded. Further, the series scene mode can be released not only when the film is finished but also when the film is taken out halfway before the film is finished.

Further, although the series scene is automatically released at the time of film end or film exchange here, photometry is performed when the power switch of the camera is turned off or when the release switch is locked by the switch of the camera. The series scene mode may be automatically canceled or a warning may be issued when the switch is turned off or when continuous photometry is completed.

Further, in the present invention, as described above, the series scene mode is automatically released when it is better to release it automatically. However, it is not automatically released, and a warning is given to the display section. It is also possible to let the user determine whether or not to cancel the series scene only by displaying it.

(Third Embodiment) FIG. 5 is a flow chart showing the operation of a magnetically recordable camera (microcomputer) according to the third embodiment of the present invention, which will be described below with reference to this flow chart. The circuit configuration of the camera is the same as that shown in FIG.

When the main switch (not shown) is turned on, the microcomputer 1 starts operation from step 301.

In step 301, the switch SS
Whether or not _SW is turned on is determined. If it is turned on, the process proceeds to step 302, and if not turned on, the step 30 is performed.
Proceed to 9.

In step 302, the flag in the RAM 7 is discriminated, and if the series scene mode is set, the process proceeds to step 307. Here, the flag in the RAM 7 is released from the switch SS_SW and the process proceeds to step 308.

If the series scene mode is not set in step 302, the process proceeds to step 303,
It is determined whether or not the value of the film counter in the RAM 7 reaches the number of frames detected by the filmable frame number detecting means (not shown) and the film is the final frame. Proceed to step and switch SS_S when the series scene mode is not set.
When W is operated to set the series scene, the series scene mode setting prohibition warning is displayed on the display unit 6 because the film is the last frame, and the step 3
Go to 09.

If the film is not the final frame in step 303, the process proceeds to step 304. And
In this step 304, the flag series scene mode in the RAM 7 is set to set the series scene mode, and in the following step 305, the "series scene" is set.
Is displayed on the display unit 6, and the process proceeds to step 309.

Up to this point, when the series scene mode is not set and the film is not the final frame, the switch SS_SW is turned on to enter the "series scene mode", and the switch SS_SW is set in the series scene mode.
When is turned on, the "series scene mode" is released, and the series scene is set and released by operating the switch SS_SW.

Next, in step 309, it is judged whether or not the switch SW1 is turned on. If not, the process returns to step 301 to detect the state of the switch SS_SW and wait for the switch SW1 to be turned on. .

On the other hand, if the switch SW1 is ON, the process proceeds to step 310 to start the photometry m distance measurement, and in order to determine the proper exposure value, the photometry circuit 2 performs photometry to measure the light amount of the subject. The exposure amount is determined, the aperture value and the shutter speed are then determined, and the process proceeds to step 311. Then, in step 311, distance measurement is performed by the distance measuring circuit 3, the lens (not shown) is operated to focus on the subject, and the process proceeds to step 312.

In the next step 312, it is judged whether or not the switch SW2 is ON, and if it is not ON, the process returns to step 301. If it is ON, the process proceeds to step 313 to perform the exposure operation, and the aperture control circuit 5 is first.
Is operated to reduce the aperture of the lens to the value determined in step 310 above, and then the shutter control circuit 4 is operated to control the shutter at the shutter speed determined in step 310 above to perform the exposure operation, and then the aperture control. Circuit 5
Is operated to return the aperture to the open state to end the exposure operation, and the process proceeds to step 314.

At step 314, the film feeding motor 17 is operated to start the film winding operation, and at step 315, the magnetic recording circuit 14 is operated to cause the magnetic head 15 to rotate the film 18.
The recording of the shooting data such as the date is started in the magnetic recording section of No. 3, and the process proceeds to step 316.

In the next step 316, the RAM 7
The series scene mode flag therein is discriminated, and if it is not the series scene mode, the process proceeds to step 317. And
In this step 317, since there is no series scene mode, if the series scene continuation flag in the RAM 7 is set, it is cleared and the process proceeds to step 320.

If the series scene mode is set in step 316, the process proceeds to step 318, where it is determined whether or not the series scene continuation flag in the RAM 7 is set. If not, the process proceeds to step 319. Then, in step 319,
The series scene continuation flag in the RAM 7 is set and the process proceeds to step 320.

In step 320, the series scene start signal is recorded in the magnetic recording portion of the film 18. This step is for when not in series scene mode,
It is set to the series scene mode and is executed when the first picture is taken.

If the series scene continuation flag is set in step 318, step 32
In step 1, the series scene end signal is recorded in the magnetic recording portion of the film 18. This step is executed when the second and subsequent images are taken after the series scene mode is entered.

In the next step 322, all the magnetic recording data to be recorded is recorded on the film, and if this magnetic recording operation is erroneously finished, the process proceeds to step 323. Then, in this step 323, when it is detected by the film detection circuit 14 and the photo sensor 15 that the film 18 has reached the predetermined position where one frame has been fed, the film feeding circuit 16 causes the film feeding motor 17 to move. The operation is stopped, the value of the film counter of the RAM 7 is incremented by 1, the display of the film counter of the display unit 6 is also incremented by 1, and the process returns to step 310 to end the series of release operations.

As described above, even if the series scene mode is set for the last frame of the film, the series scene setting prohibition warning is issued without setting the series scene mode.

In addition to the present embodiment, when it is attempted to set the series scene mode in the last frame of the film, it is also possible to set the series scene mode and warn only that there is no meaning. .

In step 403 of FIG. 6, it is judged whether the mode is the constant print condition mode in which the print conditions such as the print time and color correction for all the films are constant, and whether the series scene mode is set or not. If it is in the constant print condition mode, the series scene is not set and the series scene setting prohibition warning is issued in the next step. If the mode is not the constant print condition mode, the series scene is set.

Here, as described in the second embodiment, there is also a method in which the series scene mode is set and only a warning is issued, and whether or not the series scene mode is set is determined by the user's judgment.

There is also a method in which neither the "series scene start signal" nor the "series scene end signal" is recorded when the print condition constant mode is set. By this method, the recording capacity of the magnetic recording section has a margin. It is also possible to record other information.

According to each of the above embodiments, the following effects are obtained.

1) When a different film is loaded, such as when the exposure mode such as the program AE or the shutter priority AE is changed, when the film is finished, or when the film is replaced, the power of the camera is turned off. When it is apparently not consecutive shooting, etc., the mode for automatically recording the series scene signal is released and the photographer is warned, so that unintended photographs will be completed Can be prevented in advance.

2) It is possible to cancel the series scene by notifying the photographer that it is better not to record the series scene, and canceling the series scene by issuing only the warning without automatically canceling the series scene.

3) When it is detected that the film is the last frame, at this time, even if an attempt is made to set the series scene mode, a warning is given without setting, or a warning is given even if setting is made. As a result, unnecessary operation is not performed.

4) In the mode in which the constant print condition signal is recorded, even if an attempt is made to set the series scene mode, a warning is given without setting, or a warning is given even if setting is made. It is possible to prevent meaningless recording operation and increase the recording capacity of necessary information.

Further, according to the present invention, for example, in the print instruction mode in which the recording of the signal to the effect that the continuous plural frames are to be printed under the same condition is recorded in the magnetic recording portion of each frame, the photographing is performed, for example, When an operation that should be canceled should be performed, such as a film rewinding operation or a camera power off operation, the print instruction mode is canceled or shooting in that mode is not appropriate. A warning to that effect is given, or the print instruction mode is canceled and the warning is given.

Further, according to the present invention, for example, in the print instruction mode in which the recording of the signal to the effect that the continuous plural frames are to be printed under the same condition is recorded in the magnetic recording portion of each frame, the photographing is performed, for example, When it detects that all frames have been shot, or that the continuous photometry operation has been finished, it cancels the print instruction mode and warns that shooting in this mode is not appropriate, Alternatively, the print instruction mode is canceled and the warning is issued.

Further, according to the present invention, when it is detected by the film detection means that the film is the last frame, a signal indicating that it is desired to print a plurality of continuous frames under the same condition is recorded. You can prohibit the setting of the print instruction mode that causes the magnetic recording unit to perform shooting,
A warning that shooting in this mode is not appropriate, or
The print instruction mode is prohibited and the warning is issued.

Further, according to the present invention, the second print instruction mode for executing the photographing in which the magnetic recording portion of each frame is recorded with a signal indicating that printing is to be performed under the same conditions for all the films At times, it is prohibited to set the first print instruction mode that causes the magnetic recording portion of each frame to perform the recording of the signal indicating that the continuous plural frames are to be printed under the same condition, or to prohibit the setting of the first print instruction mode. In this case, a warning that the photographing is not appropriate is issued, or the print instruction mode is prohibited and the warning is given.

Therefore, it is possible to prevent the photographer from obtaining the photograph of the exposure which is not intended by the photographer, or to record the meaningless signal to the effect that the plural consecutive frames should be printed under the same condition. Can be
