2. Description of the Related Art It has been proposed to record various photographic information such as light source type information and trimming information on a magnetic recording layer of a photographic film or an IC card during photographing (for example, Japanese Patent Laid-Open No. 62-208028 Public bulletin).

0003

[Problems to be Solved by the Invention] Even with cameras that record photographic information, etc., the process of taking out the film from the camera is usually the same as with conventional cameras, and usually takes a specified number of shots for one roll of film. This will be done at the time the photo is taken. However, there may be times when you want to take a new photo using a film with a different sensitivity or another type of film than the film you are currently shooting, and in this case, you may want to rewind the film you are currently shooting.
Load new film into the camera. Further, when the film is being rewound during shooting, the leading end of the film is usually wound up inside the cartridge. Therefore, in order to use the film in the middle of shooting again for shooting, it is necessary to use a film tip ejecting tool or the like to take out the leading edge of the film from the cartridge, which requires a cumbersome operation. Furthermore,
Even when the leading edge of the film is removed from the cartridge, it is impossible to accurately determine the final position of the photographed frames, making it difficult to reload the film. Moreover,
In an information recording camera that stores photographic information on an IC card, it is necessary to compare the film with the IC card that stores the photographic information and then reload the film, making the operation even more troublesome for the user.

The present invention has been made to solve the above-mentioned problems, and even if a film with unphotographed portions that have not reached the specified number of shots is taken out midway through, the film can be reloaded into the camera during shooting. To provide an information recording camera which can easily take pictures again following a photographed frame. Another object of the present invention is to provide a DP reception machine that automatically matches a film photographed using such a camera with an IC card.

[0005]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a camera having a removable IC card in which various information is written. means for reading information identifying the type of film, means for storing the read film identification information in the IC memory, means for storing the number of shots in the IC memory after the shooting of each frame is completed, and a means for reading information for identifying the type of film; an input means for instructing to take out the film and IC memory before the number of sheets has been reached; a means for winding the film into the film cartridge when the input means instructs to take out the film halfway; When the film and IC memory are reloaded, a means for reading identification information of the reloaded film and IC memory and determining whether or not these identification information match, and a means for identifying the film if they match; The camera is equipped with a means for displaying the information and the number of photographed frames, and a means for setting the next unphotographed frame of the film after the photographed frame in the photographing frame when they match. In another invention, instead of storing the number of shots taken on the IC card after each frame has been taken, the number of shots taken is stored on the IC card when an instruction is given to take out the film halfway. . Another invention provides a means for reading photographing information and cartridge verification information stored in a camera IC card, a means for reading IC card verification information recorded on a photographed film cartridge, and a means for reading photographic information and cartridge verification information stored in a camera IC card, and a means for reading photographic information and cartridge verification information stored in a camera IC card. If the information matches,
A DP reception machine is constituted by a means for writing photographing information stored in a camera IC card and cartridge collation information into a print IC cartridge.

[0006]

[Operation] When a film cartridge is set in the cartridge storage section of a camera, film identification information such as the film manufacturer, film sensitivity, number of shots, etc. is read out. This film identification information is then stored in an IC card set in the camera together with the film. and,
Each time a photograph is taken, photographing information and photographed information are stored in the IC card. When taking out the film from the camera in the middle of shooting, when the number of shots that can be taken has not yet been reached, the film halfway take-out switch is operated, and the film is wound into the cartridge. When the partially removed film is to be used again for photographing, the film and the IC card are reloaded into the camera. Film identification information is read from the reloaded film cartridge. Further, the film identification information is also read out from the reloaded IC card. If the identification information matches, the identification information, the number of captured images, etc. are displayed on the display section of the camera. Furthermore, the unexposed portion following the already photographed frame is set in the camera's photographing frame, allowing the next frame to be recorded following the already photographed frame.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 2 shows a film cartridge 10 having a film cue function. This film cartridge 10 is basically the same as a conventional film cartridge, and includes a cartridge body 11, a spool 12 rotatably attached within this cartridge body 11,
It is composed of a photographic film 13 whose one end is fixed to the spool 12 and wound and stored therein. The cartridge body 11 is formed into a cylindrical shape by joining half members made of synthetic resin, and has an opening 16 for the film 13,
A hole 18 is provided for exposing the engagement end 17 of the spool 12 to the outside. And film entrance/exit 16
A light-shielding telescope 19 is attached to. Further, the film storage chamber 20 of the cartridge body 11 has a spool 1
The inner diameter of the film 13 is approximately the same as the maximum winding diameter when the film 13 is wound up. As a result, when the spool 12 is rotated in the film feeding direction opposite to the film winding direction, the leading end of the film 13 is guided by the inner wall surface of the film storage chamber 20, and the film can be guided to the outside through the film opening 16. .

The leading end portion 13a of the film is roundly cut to reduce film feeding resistance when the film is taken out and when the film is guided to the winding shaft on the camera side. A perforation 21 is formed in this tip 13a, and a sprocket on the camera side engages with this to feed the film tip 13a to the winding shaft inside the camera after the film is positioned. Further, the perforation 21 is engaged with a claw on the winding shaft of the camera, so that the film is reliably wound onto the winding shaft. Further, the image recording section 13b has a positioning perforation 22.
One perforation is formed in each frame 23, and by mechanically or optically detecting this perforation 22, each frame 23 of the film is sequentially set in the exposure frame of a camera or the exposure position of a printer. On the opposite side from the photosensitive emulsion surface, a long track-shaped magnetic recording layer 14 is formed in the film feeding direction, and if necessary, photographing information and print information can be magnetically recorded during photographing or printing processing. can do.

As shown in FIG. 3, the camera is provided with an IC card reader/writer 30. An IC card 31 is inserted into the IC card slot of the IC card reader/writer 30. Further, a film identification information reading section 32 is provided in the cartridge storage section of the camera. The film identification information reading section 32 includes nine electrical contacts 33a to 33i and an encoder 34. An electrical contact pattern 35 is formed on the circumferential surface of the film cartridge 19 to indicate film identification information such as the film manufacturer, sensitivity, and number of shots that can be taken. Among the electrical contacts 33a to 33i, the contact 33a is a common contact. Further, 33b to 33d are contacts for identifying film manufacturers, and six film manufacturers are identified by a combination of patterns that contact these three contacts. Also, 33
e to 33g are contacts for identifying film sensitivity, and six film sensitivities, e.g. ISO25, 100, 200, 400,
1600, 3200 are identified. Also, 33h, 33i
is a contact point for identifying the number of shots that can be taken with the film, and the number of shots that can be taken up to four is identified by a combination of patterns touching two contacts.

The encoder 34 has electrical contacts 33a to 33a.
The read signal of the contact pattern 35 from the camera 33i is converted into an information signal indicating the film manufacturer, film sensitivity, and number of shots, and this signal is sent to the camera controller 36. The controller 36 is composed of a well-known microcomputer, and stores the read film identification information in the IC card 31 based on the film set signal. controller 3
6 is also connected to a display 37, an alarm 38, a data generation circuit 39, a release switch 40, and a film winding switch 41.

[0011] The data generation circuit 39 is connected to various switches, a detection section, and the like. The zoom switch 43 sends a zoom magnification signal to the data generation circuit 39 for performing pseudo-zooming printing. Further, the panoramic print designation switch 44 is operated when panoramic printing is desired. The auto date mechanism 45 records the date and time of photography. Further, the light source detection section 46 detects the type of light source and sends it to the data generation circuit 39. The main subject position detection section 47 detects the main subject position and sends it to the data generation circuit 39. The method of detecting the type of light source is described in detail in, for example, Japanese Patent Application No. 1-304487. Also, regarding the method of detecting the position of the main subject,
This is explained in detail in Japanese Patent Application No. 1-208834. The data generation circuit 39 generates data representing various photographic information corresponding to signals from various switches, etc., and sends the data to the controller 36. controller 36
writes various information to the IC card 31 based on the release signal from the release switch 40. At this time, the controller 36 counts the number of frames that have been shot based on the release signal from the release switch 40, identifies each frame based on this count, and displays various shooting information in correspondence with this. Write to IC memory 31. Further, the controller 36 writes photographed information for each photographed frame in addition to each photographic information. In addition to writing this photographed information, the number of photographed frames may also be recorded.

During the release operation, an image of the subject is recorded on the photosensitive emulsion surface of the film 13 via the photographic lens 48, diaphragm, and shutter mechanism 49, as is well known. In addition, IC
In addition to recording data in the memory 31 each time a photograph is taken, the memory of the controller 36 stores data for one film. Based on the take-up signal, the data may be recorded all at once before or after the film is wound.

The film winding switch 41 is operated to take out a film in which a predetermined number of frames have not yet been photographed. A signal from this switch 41 is sent to the controller 36. The controller 36 takes out the film 13 based on this film mid-takeout signal.
is wound up into the cartridge body 11.

[0014] In addition to the above, the camera may also record information indicating whether or not a strobe is emitting light, subject distance information, focal length information of a photographic lens, and the like. Further, portrait information and background information may be recorded as print designation information for the laboratory, and for example, in the case of portrait photography, exposure may be performed with emphasis on skin color. In addition, as print specification information, information indicating the shooting environment (for example, a candle service at a wedding or an outdoor commemorative photo shoot) is recorded, and when printing, the exposure amount is corrected using general exposure correction data for the scene. You may also do so.

Next, the operation of the above camera will be explained. At the beginning of shooting, there are 10 film cartridges in the camera.
and the IC card 31 are loaded. When the IC card 31 is inserted into the camera, as shown in FIG.
6 reads data from the IC card 31. and,
It is determined whether there is data during shooting. The presence or absence of this data during shooting is determined based on whether or not film identification information is recorded on the IC card 31. If the film identification information is not recorded on the IC card 31, it is determined that the photographing is with a new film, and in this case, the process waits for the cartridge to be installed. When the cartridge is loaded into the camera, film identification information consisting of the film manufacturer, film sensitivity, and number of shots is read from the contact pattern 35. Thereafter, this film identification information is written into the IC card 31, and this film identification information is displayed on the display 37. Thereafter, the beginning and initial feeding of the film 13 are performed. As a result, the leading end 13a of the film is ejected from the cartridge body 11 and wound onto the winding shaft of the camera, and the camera waits for the release operation.

[0016]Furthermore, the film identification information is stored in the IC card 31.
If it has already been recorded, it is determined that the photographing is being performed using a reloaded film, and a display indicating that the photographing is in progress is displayed. As a result, the film manufacturer, sensitivity, number of shots, and number of shots being taken are displayed on the display 37. After this, the process waits for the film cartridge 10 to be loaded. When the film cartridge 10 is loaded into the camera, the contact pattern 35
Film identification information is read from. If the read film identification information matches the film identification information on the IC card 31, the film 13 is fed to the next frame after the photographed frame. This film set detects perforations 22 and performs processing based on the number of perforations detected. After that, the camera waits for the release operation. If the film identification information does not match, an alarm 38 is issued and the cartridge is placed on standby for reloading.

When photographing, as shown in FIGS. 3 and 4, when the release switch 40 is turned on, light metering and distance measurement are carried out as is well known, and thereby the aperture and shutter speed are set and the focus is adjusted. be exposed. Thereafter, the shutter mechanism 49 is activated to form an image of the subject on the photosensitive emulsion surface of the film 13. Further, photographing information from various switches and detection units is stored in the IC card 31 for each photographed frame. Similarly, photographed information is recorded for each frame. After this, the film 13 is advanced frame by frame. When the prescribed number of images have been photographed, the controller 36 issues a film rewind signal to rewind the film 13. Further, when taking out the film before the prescribed number of sheets has been reached, the film winding switch 41 is operated. This switch 41
In response to the ON signal from the controller 36, the controller 36 issues a film winding signal and rewinds the film 13. After rewinding, the cartridge 10 and IC card 31 are removed from the camera.

When accepting DP processing, the camera IC card 31 is loaded into the IC card reader 61 of the reception machine 60, as shown in FIGS. 5 and 6. The reception machine 60 includes a reception machine main body 62 made of a well-known personal computer, an IC card reader 61, and an IC card writer 63. The IC card reader 62 reads film identification information and shooting information from the IC card 31 on the camera side.
This is sent to the reception machine main body 61. The reception machine main body 61 displays the read film identification information on the display 65. Further, reception information such as a reception ID number and reception processing details are input into the reception machine main body 61 by operating the keyboard 66. The input reception information and photographing information are written to the print IC card 67 by the IC card writer 63. When a predetermined number of orders is stored in the print IC card 67, the film cartridge 10 and the print IC card 65 are sent to a developing laboratory.

At the time of acceptance processing, as shown in FIGS. 5 and 6, first, the IC card reader 61 reads film identification information from the IC card 31 on the camera side. This is then displayed on the display 65. The operator compares this display with the film identification information of the film cartridge 10, and if they match, inputs the reception information using a key. The reception machine main body 62 reads data from the camera-side IC card 31 and transfers the data and reception information to the print IC card 65. Thereafter, the camera-side IC card is taken out from the reception machine and returned to the user. Furthermore, if the DP reception store does not have such a reception machine, the film and IC card are sent to a photofinishing laboratory, where the same reception processing is performed.

[0020] The above embodiment has been explained by taking as an example a camera of the type that takes the film out of the cartridge and takes pictures one after another. The invention may also be applied to a pre-winding type camera in which the film is sequentially wound and stored in a cartridge. In this case, identification information for identifying whether the photographic film is a pre-winding film or another method is stored in the IC card. In addition, in the above embodiment, the contact pattern recorded on the circumferential surface of the cartridge was used as film identification information, but in addition to this, the film manufacturer, sensitivity, number of sheets, etc. were recorded using a bar code or Carla code method, and this was optically recorded. may be detected. Alternatively, a magnetic recording surface may be formed on the circumferential surface of the cartridge, and the film identification information may be magnetically recorded on this surface.

Further, in the above embodiment, the operator takes the film cartridge 10 and the IC card 31 at the time of DP reception.
In addition to this, automatic verification may be performed using the reception machine. In this case, as shown in FIGS. 7 and 8, an individual ID number 72 of the film cartridge 71 and a bar code 73 representing the ID number 73 are written on a part of the surface of the cartridge body 70 during manufacturing or use of the film cartridge. Record it at the time.

At the time of DP reception, as shown in FIG. 7, a DP reception machine 80 similar to that of the above embodiment is used. In this case, a cartridge checker 8 is installed in the reception machine main body 62.
Connect 1. This cartridge checker 81 is equipped with a barcode reader 82 and reads the individual ID number barcode 73 of the film cartridge 71. This read signal is sent to the reception machine main body 62. The reception machine main body 62 receives the individual ID from the cartridge checker 81.
The number is compared with the individual ID number recorded on the camera IC card 83. If the individual ID numbers match, the reception machine main body 62 further reads the photographing information from the IC card 83 and records it on the print IC card 65. Further, if the individual ID numbers do not match, an alarm is generated and writing of photographing information and the like to the print IC card 65 is stopped. In this embodiment, the film cartridge 71 and the camera IC card 83 are identified based on the individual ID number recorded on the cartridge body 70.
In addition to this, a magnetic recording layer may be formed on the cartridge body 70 and the individual ID number may be magnetically recorded thereon. Furthermore, an individual ID number or the like may be recorded on the magnetic recording layer at the leading end of the film.

[0023]

[Effects of the Invention] As explained above, according to the present invention,
Film identification information is recorded on the film cartridge, and this information is read and stored on the camera's IC card, so even if the film is removed from the camera in the middle of shooting before the specified number of shots has been reached, the film and its IC card will remain intact. Automatic verification can be performed. Moreover, since the photographed information is recorded on the IC card, the unexposed portion of the reloaded film corresponding to the next frame following the photographed frame can be automatically set at the photographing position of the camera. Further, when accepting DP processing, it is also possible to automatically compare the film and its IC card.
