It is conceivable that the information will be written using a recording-only device later, but there is a problem that a special device other than the camera is required.

Similarly, since the photographic information is written in the information recording area only with the exposure operation, it is not possible to write the photographic information later in the photographed film by using the information recording device attached to the camera. Therefore, there is a problem that a special device dedicated to recording is required to write the photographing information later.

It is an object of the present invention to provide a camera having an information recording device capable of later writing photographic information on a photographed film without requiring a special device.

In step S309, the control circuit 11 stops the forward rotation of the film feeding motor 21 via the feeding motor driving circuit 20, and stops the film winding operation. The above procedure is well known. After this, the subroutine ends and the program returns to the main routine shown in FIG.

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

First, by turning on a power switch of a camera (not shown), the camera shifts to a mode selection state (step S101). Then, the mode setting switch SW3
Either the recording-only mode or the shooting mode is selected and set by, and thereafter, the camera operates according to 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 the half-press switch SW1 is turned on to start reading the photographing information (step S202).

First, the photographing information stored in the memory 42 of the camera 2 is read, and this is read in the memory 34 of the camera 1.
Stored and stored in (steps S203 to S20)
4). Next, the liquid crystal display device 29 displays the photographing information of the first frame (usually the frame of the smallest frame number) to be recorded (step S205), and in this state, waits for the recording mode setting switch SW4 to set the recording mode. Becomes When the recording mode setting switch SW4 is used to set whether to continuously record all frames or to record one frame at a time, a different operation is performed based on the setting result.

When all the frames are set to be continuously recorded, the state of waiting for the input of the setting result from the recording change setting switch SW5 is entered, and the photographing information of the first frame is changed by the recording change setting switch SW5. When the effect is set, the shooting information is added by the operation switch group 35,
Change and deletion are performed (step S208). On the other hand, if the setting indicating that no change is made is made, the program is in a state of waiting for an input from the next frame display switch or 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, the photographing information is changed or not and a change operation is performed if necessary. (Steps S212 to S213). Then, the above operation is repeated to perform the changing operation for the shooting information of the frame that needs to be changed. On the other hand, when the full-press switch SW2 is turned on, recording of shooting information is started.

When the setting for recording each frame is made, whether or not the photographing information is changed at each recording is set. Therefore, the photographing information is not changed at this point, and the full-press switch is pressed. Recording of shooting information starts after the SW2 is turned on.

Since the film 50 has not yet been wound up at this stage, the film 50 is automatically wound up to the first frame to be recorded, and the film 5 is wound in the middle of this winding operation.
The film information written in the magnetic recording area 52 of 0 is read by the magnetic head 26 (step S217-).
S219). Then, it is determined whether or not the read film information and the shooting information in the memory 34 match, and if they match, the next operation is performed. If they do not match, subsequent information writing The operation is stopped (steps S252 to S256). That is, in this embodiment, since the shooting information is not written to the film at the same time as the shooting operation, it is necessary to confirm in advance whether the shooting information in the memory 34 is the information about the film 50 loaded in the camera 1. To do this. At the same time, the liquid crystal display device 29 and the buzzer 31 also display the content mismatch.

The information recording operation differs depending on the setting result of the recording mode setting switch SW4. First, 1
If the recording is set for each frame, 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. To do. Then, similarly to the above, the recording change setting switch SW5 and the operation switch group 35 are used to determine whether or not the photographing information is changed, and to change the photographing information as necessary (steps S226 and S227).
After that, waiting for the full-press switch SW2 to be turned on, information recording for one frame is performed (steps S229 to S231).
Then, the above operation is performed for all the frames to be recorded.

On the other hand, when it is set that all frames are continuously recorded, the encoder 27 selects the first frame to be recorded.
And information is recorded (steps S236 to S236).
After 238), frame detection (step S241) and information recording operation (step S243) are continuously performed without stopping the film winding operation. Then, the above operation is performed for all the frames to be recorded. When all frames are continuously recorded, the film 50 can be collectively recorded without stopping the film winding operation, so that information can be recorded at a stable film winding speed. Further, in the present embodiment, since only the frames that require recording are selected and the film 50 is wound up, there is less risk of scratching unnecessary portions of the film 50, and the time required for recording information is reduced. Is also shortened. For example, when recording information on only 1 to 5 frames, the information recording operation is completed by winding the film 50 up to the 5th 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 this time (steps S244, S24).
5). At this time, since the magnetic head 26 is in a state of touching the film 50, while the film 50 is being rewound, the photographic information just written by the magnetic head 26 is read, and comparison / collation with the photographic information in the memory 34 is performed. If there is a frame that does not match as a result of the collation, this is displayed (step S250), and the rerecording setting switch S is displayed.
After waiting for the setting by W6, the photographing information is re-recorded if necessary. This re-recording may be performed only for the pieces that do not match.

In the above operation, the touch and detachment of the head 26 is frequently repeated to prevent the film 26 from being scratched by the head 26, and
This is because the film information is not erased more than necessary when the frames to be recorded are not continuous.

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

Therefore, according to the present embodiment, even if the film 50 photographed by the camera 2 having no information recording device is stored and stored in the memory 42,
This shooting information can be recorded in the recording-only mode of the camera 1. Moreover, 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 this embodiment, since the shooting information for each frame can be changed at the time of recording the information, even if the shooting information is forgotten but is taken by a camera having an information recording device, The camera 1 of this embodiment can be used to add shooting information later, and conversely, unnecessary shooting information recorded during shooting can be deleted later.

-Second Embodiment- FIG. 11 is a perspective view showing a second embodiment of a camera having an information recording apparatus according to the present invention. In this embodiment, the memory card 60 is inserted into the camera 2 that does not include the information recording device, and the photographing information is stored and stored in the memory card 60. Slots 1a, 2a of a memory card 60 are formed in both cameras 1 and 2, respectively, and shooting information is exchanged via the memory card 60. That is, in the first embodiment described above, 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 as well, it is possible to obtain the same effects as those of the first embodiment described above.

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

Further, the collating operation of the information on the film 50 and the information in the memory 34 before and after the writing of information is not essential and can be omitted if necessary. On the other hand, it is not necessary to record all of the photographing information on the film 50. When recording all frames continuously, a frame selection switch is provided to select only the desired frame, and when recording one frame at a time, frame skipping is performed. It is also possible to provide a switch to skip pieces that do not need to be recorded.

Further, in the embodiment, the half-push switch SW1 is used for the information reading command and the full-push switch SW2 is used for the information recording command, but another switch may be substituted or a dedicated switch may be provided. Good.

[0069]

As described in detail above, according to the present invention, since the photographing information inputted from the outside can be recorded in the information recording area of the film, the photographing can be carried out by a camera without an information recording device. It is possible to write shooting information later on a film that has already been shot, for which shooting information needs to be written after shooting, such as a recorded film, by the recording-only mode of the camera. Moreover, 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, since it is possible to change the photographing information for each frame at the time of recording the information, for example, in the case where the photographing information is taken by a camera having an information recording device but the photographing information is forgotten to be recorded Even if there is, shooting information can be added later by using the camera of this embodiment, and conversely, unnecessary shooting information recorded at the time of shooting can be deleted later.
