Thereafter, the subroutine ends and the program returns to the main routine shown in FIG.

(3) Shooting Mode (FIG. 10) When the program proceeds to step S103, the subroutine program shown in FIG. 10 starts. First, in step S301, the process waits for the ON determination of the half-press switch SW1, and when the ON determination is made, the process proceeds to step S302. In step S302, a photometric operation is performed by the photometric element 15 and the photometric device 14, and in step S303, a distance measuring operation is performed by the CCD 13 and the focus detection device 12.

Next, in step S307, the film feed motor 21 is rotated forward via the feed motor drive circuit 20 by a command from the control circuit 11, and the film winding operation is performed. In step S308, a series of magnetic recording operations are performed. That is, after the magnetic head 26 is brought into contact (touch) with the magnetic recording area 52 of the film 50 by the recording magnetic head drive circuit 25, one frame of photographing information is written by the magnetic head 26, and the magnetic head 26 It is evacuated (detached) from the film 50. In step S309, the control circuit 11 stops the normal rotation of the film feed motor 21 via the feed motor drive circuit 20, and stops the film winding operation. The above procedure is well known. Thereafter, the subroutine ends and the program returns to the main routine shown in FIG.

Now, a specific operation of the camera according to the present embodiment will be described based on the above description of the flowchart.

First, when a power switch of a camera (not shown) is turned on, the camera shifts to a mode selection state (step S101). And the mode setting switch SW3
Selects one of the recording-only mode and the photographing mode, and thereafter, the camera operates in accordance with each mode.

First, the recording-only mode will be described. When the recording-only mode is set by the mode setting switch SW3, the fact is displayed on the liquid crystal display device 29 (step S201), and reading of the shooting information is started by turning on the half-press switch SW1 (step S202).

First, the photographing information stored in the memory 42 of the camera 2 is read, and the read information is stored in the memory 34 of the camera 1.
(Steps S203 to S20)
4). Next, the photographing information of the first frame to be recorded (usually the frame with the youngest frame number) is displayed on the liquid crystal display device 29 (step S205). In this state, the recording mode setting switch SW4 waits for the recording mode setting. Becomes When the recording mode setting switch SW4 sets whether to record continuously for all frames or for each frame, different operations are performed based on the setting result.

When the setting to record all frames continuously is made, the state of waiting for input of the setting result from the recording change setting switch SW5 is awaited, and the photographing information for the first frame is changed by the recording change setting switch SW5. When the setting to the effect is made, addition of shooting information by the operation switch group 35,
Changes and deletions are performed (step S208). On the other hand, when the setting for not changing is made, the program waits for an input from the next frame display switch or the full-press switch SW2. When the next frame display switch is turned on, the photographing information of the next frame to be recorded is displayed on the liquid crystal display device 29 (step S211), and similarly, whether or not this photographing information has been changed and a change operation is performed as necessary. (Steps S212 to S213). Then, the above operation is repeated, and the change operation is performed on the photographing information of the frame that needs to be changed. On the other hand, when the full-press switch SW2 is turned on, recording of photographing information starts.

When the setting for recording for each frame is set, whether or not the photographing information is changed is set each time at the time of recording. Therefore, the photographing information is not changed at this point. The recording of the photographing information starts after the SW2 is turned on.

At this stage, since the film 50 has not been wound up yet, the film 50 is automatically wound up to the first frame to be recorded.
0 is read by the magnetic head 26 (steps S217 to S217).
S219). Then, it is determined whether or not the read film information and the photographing information in the memory 34 match, and if they match, the process proceeds to the next operation. The operation is stopped (steps S252 to S256). That is, in this embodiment, since the photographing information is not written on the film at the same time as the photographing operation, the operation of confirming whether or not the photographing information in the memory 34 is the information on the film 50 loaded in the camera 1 is performed in advance. To do it. At the same time, the inconsistency of the contents is displayed by the liquid crystal display device 29 and the buzzer 31.

The information recording operation differs depending on the result set by the recording mode setting switch SW4. First, 1
If it is set to record for each frame, after the first frame to be recorded is detected by the encoder 27 (step S223), the film winding operation is stopped and the photographing information is displayed on the liquid crystal display device 29. I do. Then, in the same manner as described above, the photographing information was changed by the recording change setting switch SW5 and the operation switch group 35, and the photographing information was changed if necessary (steps S226 and S227).
Thereafter, the information recording for one frame is performed after the full-press switch SW2 is turned on (steps S229 to S231).
The above operation is performed for all the frames to be recorded.

On the other hand, if the setting is made to record all frames continuously, the first frame to be recorded is recorded by the encoder 27.
And the information is recorded (steps S236 to S236).
238) After that, frame detection (step S241) and information recording operation (step S243) are continuously performed without stopping the film winding operation. The above operation is performed for all the frames to be recorded. When all frames are continuously recorded, since the film winding operation can be performed collectively without stopping, information can be recorded at a stable film winding speed. Further, in the present embodiment, the winding operation of the film 50 and the like are performed by selecting only the frames that need to be recorded, so that there is little risk of damaging unnecessary portions of the film 50, and the time required for information recording is reduced. Is also shortened. For example, when information recording is to be performed on only one to five frames, the information recording operation is completed by winding the film 50 to the fifth frame.

When the information recording is completed for all the frames to be recorded, the film winding operation is ended and the film rewinding operation is started (steps S244 and S24).
5). At this time, since the magnetic head 26 is in a state of touching the film 50, the magnetic head 26 reads the photographic information just written while rewinding the film 50, and compares / collates the photographic information with the photographic information in the memory 34. If there is a non-matching frame as a result of the comparison, this is displayed (step S250), and the re-recording setting switch S
After the setting by W6, the photographing information is re-recorded as necessary. This re-recording may be performed only for the unmatched frames.

In the above operation, the reason why the touch / detachment of the head 26 is frequently repeated is to prevent the film 50 from being damaged by the head 26, and
This is because when the frames to be recorded are not continuous, the film information is not unnecessarily erased.

The operation when the photographing mode is set is the same as the operation of a camera having a well-known information recording device. That is, when the half-press switch SW1 is turned on, photometric and distance-measuring operations are performed, and when the full-press switch SW2 is turned on, an exposure operation is performed, and then information recording is performed along with film winding.

Therefore, according to this embodiment, even if the photographing information is stored and stored in the memory 42 even for the film 50 photographed by the camera 2 having no information recording device,
This shooting information can be recorded in the recording-only mode of the camera 1. In addition, this can be achieved by using the information recording function of the camera 1 without requiring a special device dedicated to recording. In particular, in the present embodiment, since the shooting information for each frame can be changed at the time of information recording, even if the shooting information is forgotten to be recorded by a camera having an information recording device, for example, Photographing information can be added later by using the camera 1 of the present embodiment, and conversely, unnecessary photographing information recorded at the time of photographing can be deleted later.

Second Embodiment FIG. 11 is a perspective view showing a second embodiment of the camera having the information recording device according to the present invention. In this embodiment, the memory card 60 is inserted into the camera 2 having no information recording device, and the photographing information is stored and stored in the memory card 60. Slots 1a and 2a of a memory card 60 are formed in both cameras 1 and 2, respectively. That is, in the first embodiment, the cable 3 and the connectors 32 and 44 are omitted, and a common memory card 60 is provided instead of the memories 34 and 42. Therefore, according to this embodiment, the same operation and effect as those of the first embodiment can be obtained.

The details of the camera having the information recording apparatus of the present invention are not limited to the above-described first and second embodiments, and various modifications are possible. As an example, the method of inputting photographing information to the camera according to the present invention is not limited to the above-described embodiment, and photographing information can be input by a well-known information transmitting means such as a wireless system.

Further, the collation operation between the information on the film 50 and the information in the memory 34 before and after writing the information is not essential, and can be omitted as necessary. On the other hand, it is not necessary to record all of the photographing information on the film 50. When continuously recording all frames, a frame selection switch is provided to select only a desired frame, and when recording each frame, a frame skip is performed. By providing a switch, it is possible to skip frames that do not need to be recorded.

Further, in the embodiment, the half-press switch SW1 is used for the information reading command and the full-press switch SW2 is used for the information recording command. However, another switch may be used instead, or a dedicated switch is provided. Is also good.

As described in detail above, according to the present invention, photographing information input from the outside can be recorded in the information recording area of the film, so that the photographing information can be photographed by a camera having no information recording device. It is possible to write the shooting information later in the recording-only mode of the camera for a film that has to be shot with shooting information after shooting, such as a shot film. In addition, this can be achieved by using the information recording function of the camera without requiring a special device dedicated to recording. Further, according to the second aspect of the present invention, the photographing information for each frame can be changed at the time of information recording. Even so, the photographing information can be added later using the camera of the present embodiment, and conversely, unnecessary photographing information recorded at the time of photographing can be deleted later.
