Here, the camera 1 has been described as having both functions of optical recording and magnetic recording, but as described in FIGS. 1 and 2, the camera 1 has at least an optical recording function. Just do it.

Further, before or after the film cartridge 2 is loaded into the camera 1, optical recording on the film is performed by using another device, for example, a device capable of optical recording only without photographing a screen. It is not necessary for the camera itself to have an optical recording function if this is possible.

FIG. 5 is an explanatory diagram showing an example of a procedure for using the recording information transcription device of the present invention. The film cartridge 2 photographed as described above is carried to a developing laboratory (hereinafter referred to as a laboratory) 55 in an undeveloped state. In the lab 55, after the film 15 is developed, the optical recording information is read by the recording information transcription device of the present invention described later, and the same film 15 is read.
After posting on the magnetic track, the customer
Return to container like 56 and return. Gartridge 56
The film 15 which has been subjected to the recording process as described above is loaded therein.
In addition to the subject image, the magnetic track is exposed. The customer loads the cartridge 56 into a known film appreciation device (not shown) and views the image recorded on the film 15. As this film appreciation apparatus, in addition to an optical appreciation apparatus such as a so-called viewer, an appreciation apparatus using electric means for converting an image into an electric signal using a photographing element and then appreciating the image on a television is also conceivable.

FIG. 1 is a block diagram showing an embodiment of the recording information transcription device of the present invention used in the laboratory 55 described with reference to FIG.

A film cartridge 60 corresponding to the film cartridge 56 shown in FIG. 5 contains a film 61 which has been subjected to the development processing. In the film 61 pulled out from the film cartridge 60, an optical track 65 having optical recording information visualized by a developing process is provided at the upper part of the screen 62, and at the lower part of the screen 62, at least a part of an unrecorded part is provided. Existing magnetic tracks
63 are provided. Here, the screen 62 is the first frame of the film 61, and the perforation P ₁
Is provided, the top left corner portion, i.e., on the right top of the next screen (not illustrated) (the second frame) has perforations P ₂ is provided, which is similar to the Figure 3.

The film 61 is wound by a winding motor 74 rotating a spool 72 via a connection mechanism (not shown). The rewinding is performed by the rewinding motor 73.
Is performed by rotating a key below the film cartridge 60 via a connection mechanism (not shown).

A detection signal is generated by the LED 67 and the PD 69 in accordance with the presence of the perforation, and the feeding state of the film 61 is read based on the detection signal to perform positioning.

When reading information on the optical track 65, the luminous flux of the LED 68 illuminates the information pattern recorded on the film 61 with the feeding of the film 61, and the light enters the PD 70 provided on the opposite side of the film 61. Is possible. In other words, the information recorded in barcode format
Input to PD70. The information recorded on the magnetic track 63 is
This becomes possible by driving the recording head 71 based on the information signal while feeding the film 61.

Next, the lower circuit block in FIG. 1 will be described.
The central control is performed by the CPU 81. The recording head 71 is driven via the recording circuit 82. Information to be recorded is stored in the memory circuit 80.
Depends on the information read from The rotation of the two motors 73 and 74 is performed by controlling the drive circuit 83. The optical recording information is illuminated by the reproducing circuit 84 turning on the LED 68, and the PD 70
This is performed by detecting the light receiving signal of. The control such as the feeding of the film 61 is performed based on the light receiving signal of the PD 69 via the perforation by the driving circuit 85 turning on the LED 67.

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

This program is started in an initial state in which the film cartridge 60 is loaded into the recording information transfer 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, par file configuration P ₁ of the film 61 is LED67 and P
The state has not reached the luminous flux portion of D69.

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 1, the first screen, that is, the processing of the first frame is executed.
The counting of this count value is performed by a counting circuit in the CPU 81. Next, the LEDs 67 and 68 are turned on (step 102), and the hoist motor 74 is rotated (step 103). Thus, the film 61 is fed so as to be wound around the spool 72. Then, it is determined whether or not the perforation P ₁ (P _N ) of the first (N) frame can be detected by the PD 69 (step 104). If it can be detected, i.e., the light flux of the perforation P ₁ is LED67 as Figure 1 PD6
Immediately after reaching the position to pass through 9, the optical track 65
Pass through the PD 70, an information signal is output from the PD 70. The optical recording information obtained in this way is once captured in the CPU 81 (step 105), and the captured information is stored in the memory circuit 80 (step 106). here,
In the memory circuit 80, a memory portion, which is an area for storing information for each screen, is determined, and therefore, the address is also determined. Therefore, the information of the first screen is stored in the memory unit corresponding to the first screen in the memory circuit 80.

The feeding of the film 61 is continued during the above operation, and the next perforation P _{N + 1} is detected (step 10).
7), confirm the arrival of _{PN + 1} . When _{PN + 1} is detected, it is determined whether the operation has been performed up to the final screen (step 108). This is performed by comparing the count value N obtained by adding 1 in step 107 with the total number of screens of the film 61. As described above, a perforation is also provided at the upper left of the final screen.For example, if feeding is performed up to the final screen in the case of 36-shooting film, the perforation count value P _{N in} step 107 becomes 37, and the final Can be determined. If it is determined that the count value _PN is not yet the final value, 1 is added to N, and step
It returns to 105 (step 109). By the above operation, the information on the optical track 65 is transferred to the CPU 8 while the film 61 is fed.
1 can be stored in a predetermined area in the memory circuit 80.

If it is determined in step 108 that the count value _PN is the final value and the storage of the information on the entire screen has been completed, the winding motor 72 is stopped to terminate the feeding of the film 61 (step 110). ). Next, rotation of the rewinding motor 73, that is, rewinding of the film 61 is started (step 111). Then, the memory circuit 8 corresponding to the count value N
The CPU 81 reads the information stored in the memory unit in 0 (step 112), and reverses the order of the read information (step 113). The reason for performing the reversing operation is that the recording on the magnetic track described below is performed while rewinding the film, so that 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 area where information to be transcribed has not been subjected to recording processing at the time of photographing and is to be transcribed (step 114). The information to be added is also recorded in the area of the magnetic track area where the information to be added has not been recorded at the time of shooting as in step 114.

Next, it is confirmed whether or not the PD 69 has detected the perforation of the previous screen, that is, whether or not rewinding of one frame has been completed (step 115). When rewinding of one frame is completed, it is determined whether or not the count value N is 1 (step 116). This is a detection of 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 (step 11).
7) Return to step 112 and repeat the above operation. As described above, each time a screen is changed by feeding a film, the optical recording information of the corresponding screen stored in the memory circuit 80 is read out, the order is reversed, and the information is recorded as magnetic recording information on a magnetic track. .

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

In the above-described embodiment, the recording information transfer device of the present invention has been described as a device used in the laboratory 55. However, the present invention is not limited to this, and a recording information transfer function is provided inside the film viewing device. By doing so, it is also possible to configure so that the customer operates and transcribes necessary information. That is, if the optically recorded information is converted into magnetically recorded information before the viewing, the operation can be performed simply by reading the information on the magnetic track, so that the operation of the film viewing apparatus can be facilitated. Become. That is, if the recording information transcribing device of the present invention is applied to a film appreciation device, by using a film in which information has been transcribed from optical recording information to magnetic recording information, it is possible to read information to be read when appreciating the film. Since all the information can be reproduced only by reading the magnetically recorded information on the magnetic track, the configuration of the film viewing apparatus can be simplified.

In this embodiment, in order to record the magnetic recording information on the magnetic track 63 while rewinding the film 61, it is necessary to perform a process of reversing the order of the data of the read optical recording information. However, if the film is rewound after reading all the optically recorded information, and the magnetic recording information is recorded on the magnetic track when rewinding the film again, and then the film is rewound, the data inversion process is unnecessary. Become.

[Effects of the Invention] As described above, according to the recording information transcribing apparatus of the present invention, the optical recording information provided on the optical track of the developed film is once read, and further provided on the same film. The process of transcribing to the existing magnetic track as magnetic recording information can be performed. Therefore,
There is an effect that a large amount of information can be recorded as compared with optical recording information in which only a relatively small amount of information can be recorded.

In addition, in the case of optically recorded information, only reproduction can be performed after development, but in the case of magnetically recorded information, additional recording can be freely performed on unrecorded portions of the magnetic track when additional recording is desired. And unnecessary information can be erased.
