[Example 1 Next, the present invention will be explained with reference to the drawings.

First, a camera, which is a prerequisite for the recording information transcription apparatus of the present invention, will be explained. FIG. 3 is a configuration diagram showing an embodiment of a camera compatible with the recorded information transcription apparatus of the present invention. In FIG. 3, only the main structures of the camera 1 are shown in a simplified manner for the sake of illustration. A film cartridge 2 is loaded into the film chamber 11 on the rewind side. At the upper part of the film chamber 11, rotational force from a rewind motor 6 is transmitted to a fork 5 via a member (not shown).

The fork 5 is attached to the key 1 on the top of the film cartridge 11.
Connect with 4. A projected image of the subject is formed on a screen 18 on a film 15 through an aperture. A spool 12 is provided on the winding side, and an internal winding motor 13 is provided.
The rotational force is transmitted to the spool 12 via a member (not shown). An opening 8.9 is provided in the upper right corner of the aperture. The opening 8 is a light emitting diode (hereinafter referred to as LED).
Perforations 16 and 17 on the film 15 are detected by a photodiode (hereinafter referred to as PD) 20.
D20 is provided on the back cover (not shown) of the camera l.

The luminous flux from the LED 4 for optical recording passes through the opening 9 and is projected onto the film 15 as a narrow beam. Here, it is assumed that the recording format of the optically recorded information is a barcode format. Furthermore, a film 15 is provided on the back cover (not shown).
A recording magnetic head 3 corresponding to the upper magnetic track 21, 24 is provided.

Film 15 pulled out from film cartridge 2
A magnetic track 21 is provided at the bottom of the screen 18 on which the above-mentioned subject image is projected, and an optical track 19 is provided at the top of the screen 18 . These arrangements are the same for the screen 22 adjacent to the screen 18 and other screens housed inside the film cartridge 1. Here, magnetic recording information is recorded on the magnetic tracks 21.24 by the above-mentioned recording head, and optical recording information is recorded on the optical tracks 19.23 by the beam irradiated from the above-mentioned LED 4. It has become so. A perforation 17 is provided at the upper right end of the screen 18 in correspondence with the screen 18. Regarding the other screens, one perforation is similarly provided at the upper right of the screen corresponding to each screen. However, the final screen (not shown) in the film cartridge 2 is also provided with perforations at the upper left end of the screen, and the perforations corresponding to this final screen are used for detecting the end of the film 15, as will be described later. It looks like this.

In the circuit block diagram shown in the lower part of FIG.
U32 plays a central role in performing various controls. First, the recording head 3 is driven via the first recording circuit 33 using information from the first data selection circuit 30 . Further, the LED 4 is driven via the second recording circuit 35 using information from the second data selection circuit 3.The operation of the winding motor 131 and the rewinding motor 6 is controlled by the driving circuit 36. The film 1-5 is wound up and 2-rewinded by the above-mentioned LEDIO and PD2.
0 drive circuit 34, the perforation 16.1
This is done by detecting the position of 7. Recording on the magnetic track 21 is performed while the film 5 is being fed by driving the recording head 3 in accordance with the information to be recorded sent from the first data selection circuit 30. Note that the recording process on the magnetic track 21 is performed only on a portion of the entire area of the magnetic track 21, and the remaining portion of the entire area is used as a recording area for information to be transcribed and information to be added, which will be described later. It is secured as a storage area.

Similarly to the recording operation on the magnetic track 21, the optical 1-
Recording on the rack 19 and the like is also carried out while the film 5 is being fed by driving the LED 4 and emitting light in accordance with the information to be recorded sent from the second data selection circuit 31.

Next, the operation will be explained with reference to a flowchart showing the program of the CPU 32 shown in FIG.

This program is for film 1 in camera 1.
It is assumed that the execution is performed with the positional relationship of No. 5 shown in FIG.

First, by pressing the release button (not shown), the screen 18
An exposure operation is performed (step 41). After the exposure operation is completed, the information from the first data selection circuit 30, that is, the information to be recorded on the magnetic track 21 by the recording head 3, is temporarily stored in the CPU 32. Read (step 42).Similarly, the information from the second data selection circuit 31, that is, the optical track 1 is read by the LED 4.
9 is read into the CPU 32 (step 43). Next, the winding motor 13 is started to wind the film 15, and the next screen is moved to a position corresponding to an aperture (not shown). (step 44) and detect the perforation.
LO is turned on (step 45). Next, the recording head 3 is turned on based on the data from the first data selection circuit 30.
At the same time, the LED 4 is driven based on the data from the second data selection circuit 3 (step 46.
47>. As a result, magnetic and optical recording is made for each track 19.21 on the film 15 as it is being fed. After this, it is determined by turning on the PD 20 that the perforation 16 at the upper right of the next screen (not shown) has reached the position of the perforation 17 shown in FIG. Then, the rotation of the winding motor 13 is stopped (step 49). As a result, the next photographic screen faces the aperture, and the LED lo is turned off (step 50).

By the above-described operation, the operation of recording information regarding the screen 18 on the magnetic track 21 and the optical track 19 while feeding the film 15 is completed.

Here, the camera (2) has been described as having both optical recording and magnetic recording functions, but as shown in FIG.

As explained in FIG. 2, the camera 1 only needs to have at least an optical recording function.

Also, before or after loading the film cartridge 2 into the camera 1, another means 1, for example, optical recording on the film may be performed using a device capable of only optical recording without photographing the screen. If this is possible, there is no need for the camera itself to have an optical recording function.

FIG. 5 is an explanatory diagram showing an example of a procedure for using the recorded information transcription apparatus of the present invention. As mentioned above, the film cartridge 2 that was photographed is sent to the photo lab (in an undeveloped state).
(hereinafter referred to as the laboratory) 55. In the laboratory 55, after the film 15 is developed, the optically recorded information is read by a recording information transcription device of the present invention, which will be described later, and is transcribed onto the magnetic track on the same film 15, after which the customer is asked to put it back into a container such as a cartridge 56. I will return it. The film 15 that has been recorded as described above is loaded in the cartridge 56, and the magnetic tracks as well as the subject image on the film 15 are exposed through the opening 57 of the cartridge 56. The customer loads the cartridge 56 into a known film viewing device (not shown) and views the images recorded on the film 15.This film viewing device is a so-called pure optical viewing device. Another conceivable viewing device is one that uses electrical means to convert video into electrical signals using an image sensor and then view the video on a television.

Now, FIG. 1 shows the configuration of an embodiment of the recording information transcription apparatus of the present invention used in the laboratory 55 described in FIG. 5.

A film cartridge 60, which corresponds to the film cartridge 56 in FIG. 5, stores therein a film 61 that has undergone development processing. In the film 6↓ pulled out from the film cartridge 60,
At the top of the screen 62, an optical track 65 having optically recorded information visualized through development processing is provided.
A magnetic track 63 having an unrecorded portion at least in part is provided at the lower part of the magnetic track 2 . Here, screen 6
2 is the first frame of the film 61, and a perforation P□ is provided at the upper right of the frame, and a perforation P2 is provided at the upper left of the screen, that is, at the upper right of the next screen (second frame) not shown. 3, which is similar to that shown in FIG.

Winding of the film 61 is performed by a winding motor 74 rotating a spool 72 via a connection mechanism (not shown). Further, rewinding is performed by the rewinding motor 73 rotating a key at the bottom of the film cartridge 60 via a connection mechanism (not shown).

A detection signal is generated by the LED 67 and PD 69 depending on the presence of perforations, and based on this detection signal, the feeding state of the film 61 is read and the film 61 is positioned.

To read information on the optical track 65, as the film 61 is fed, the light beam of the LED 68 illuminates the information pattern recorded on the film 61, and the light is further incident on the PD 70 provided on the opposite side of the film 61. This makes it possible. That is, the information recorded in the barcode format is manually entered into the PD 70 as is. The recording information on the magnetic track 63 is recorded by the recording head 71 on the film 6.
This is possible by being driven based on an information signal together with the feeding of 1.

Next, the circuit block in the lower part of FIG. 1 will be explained. Central control is performed by the CPU 81. The recording head 71 is driven via the recording circuit 82. The information to be recorded is based on the information read from the memory circuit 80. two motors 73
．． The rotation of 74 is performed by controlling the drive circuit 83. The optically recorded information is recorded by the reproducing circuit 84 lighting the LED 68 and detecting the light reception signal of the PD 70 . The drive circuit 8 controls the feeding of the film 61, etc.
5 turns on the LE and D67, and is performed based on the light reception signal of the PD69 via the perforation.

3 Next, the operation will be explained with reference to the flowchart showing the program of the CPU 81 shown in FIG.

Execution of this program is started in an initial state in which the film cartridge 60 is loaded into the recorded information transcription apparatus of the present invention and the leading end of the film 61 is slightly wound around the spool 72. That is, in this initial state, unlike the state shown in FIG. 1, the perforation P0 of the film 61 has not reached the luminous flux portions ED 67 and PD 69.

First, the count value N representing the screen number of the film 61 is set to 1 (step 101). If the count value N is ■, the processing for the first screen, that is, the first frame is executed.

This count value is counted by a counting circuit within the CPU 81. Next, the LEDs 67 and 68 are turned on (step 102 >), and the winding motor 74 is rotated (step 103 >).

As a result, the film 6 is fed so as to be wound around the spool 72. Then, it is determined whether perforation 4 P□ (PN) of the 1<N> frame has been detected by the PD 69 (step 104). If the detection is successful, that is, as shown in Fig. 1, perforation P1 converts the luminous flux of LED 67 to PD6.
Immediately after reaching the position where the optical track 6 passes
5 passes through the PD 70 section, an information signal is output from the PD 70. The optical recording information obtained in this way is once imported into the CPU 81 (step 105).
, the captured information is stored in the memory circuit 80 (step 106'). Here, within the memory circuit 80, a memory section, which is an area for storing information for each screen, is determined, and therefore its address is also determined.

Therefore, the information on the first screen is stored in the memory section of the memory circuit 80 corresponding to the (2)th screen.

The film 61 continues to be fed during the above operation, and the next perforation PN+□ is detected (step 107), and the arrival of PN+1 is confirmed.

When P N+□ is detected, it is determined whether or not the operation has been performed up to the final screen (step 108).

This is done by comparing the count value N incremented by 1 in step 107 with the total number of screens of the film 61. As mentioned above, a perforation is also provided at the upper left of the final screen, so if, for example, a 36-exposure film is fed to the final screen, the count value PN of the perforation at step 107 will be 37, and at the final screen. One thing can be determined. If it is determined that the count value PN is not final yet, add 1 to N and proceed to step 10.
5 (step 109). By the above-described operation, the information on the optical track 65 can be stored in a predetermined area in the memory circuit 80 via the CPU 81 while the film 6 is being fed.

If it is determined in step 108 that the count value PN is the final value and that the storage of information regarding the entire screen has been completed,
The winding motor 72 is stopped to finish feeding the film 6 (step 110). Next, the rewinding motor 73 starts rotating, that is, rewinding the film 61 (step 111). The CPU 81 reads the information stored in the memory section in the memory circuit 80 corresponding to the count value N (step 112 > and reverses the order of the read information (step 113). The reason for performing this reversal operation will be explained below. This is because recording on the magnetic track E described above is performed while rewinding the film, and therefore the information must be recorded in the reverse order.

Then, a signal according to the inverted information is output to the recording head 71, and recording is performed in an area of the magnetic track in which information to be transcribed, which has not been recorded at the time of photographing, is to be recorded (step 114). Note that, similarly to step 114, the information to be added is also recorded in the area of the magnetic track in which the information to be added is recorded, which has not been recorded at the time of photographing.

Next, it is checked whether the PD 69 has detected a perforation one screen before, that is, whether rewinding of one frame has been completed (step 115). When rewinding for one frame is completed, it is determined whether the count value N is 1 (
Step 116>. 7. This is to detect whether or not rewinding has been performed to the first screen. If it is determined that the screen is still in the middle, 1 is subtracted from the count value N in step 117) and step 112. Return to and repeat the above steps. As mentioned above, each time the screen changes due to film feeding, the memory circuit 8
After reading the optical recording information of the corresponding screen stored in 0 and reversing its order, the optical recording information is recorded on the magnetic track as magnetic recording information.

Step 11 indicates that the above processing has been completed up to the first screen.
If confirmed in step 6, a predetermined time delay is performed (step 118).The reason for this delay is that the film 60 is not completely housed inside the film cartridge 61 at the end of step 116, and the film is This is because it takes time to finish storing the film 60 into the film cartridge 61. After this delay ends, the rewind motor 73 is stopped, the LEDs 67 and 68 are turned off, and the operation is completed (step 119).

In the above-mentioned embodiment, the recorded information transcription device of the present invention was explained as a device used in the laboratory 55, but the present invention is not limited to this, and the recorded information transcription function can be installed inside the film viewing device. By giving
It is also possible to configure the system so that the customer operates it to transfer the necessary information. In other words, if the optically recorded information is transcribed as magnetically recorded information before viewing, the operation of the film viewing device can be made easier because all that is required is to read the information on the magnetic track. Become. In other words, if the recorded information transcription device of the present invention is applied to a film viewing device, by using a film in which information has been transferred from optical recording information to magnetic recording information, information to be read when viewing the film can be read out. Since all the information can be reproduced by simply reading the magnetically recorded information on the magnetic track, the configuration of the film viewing device can be simplified.

Further, in this embodiment, in order to record magnetic recording information on the magnetic track 63 while rewinding the film 61,
Processing must be performed to reverse the data order of the optically recorded information that has been read.

However, if you rewind the film after reading all the optical recording information, record the magnetic recording information on the magnetic track when rewinding it again, and then rewind the film, data reversal processing is not necessary. Become.

[Effects of the Invention] As explained above, according to the recording information transcription device of the present invention, the optical recording information provided on the optical track of the film after development is read once, and then the optical recording information provided on the same film is read. It is possible to perform a process of transcribing as magnetically recorded information on the magnetic track located on the magnetic track. Therefore, there is an effect that a large amount of information can be recorded compared to optically recorded information that can record only a relatively small amount of information.

In addition, in the case of optically recorded information, only playback is possible after development, but in the case of magnetically recorded information, when additional information is desired to be recorded, additional recording can be freely performed on the unrecorded portion of the magnetic track. You can also delete unnecessary information.
