2. Description of the Related Art Conventionally, there has been proposed a negative film provided with a magnetic recording portion for recording information of each frame such as a photographing condition and desired print information at the time of photographing by a camera. Such a negative film is mounted on a photographic processing apparatus while being housed in a film cartridge to protect magnetic information. When a print is made from a negative film, for example, magnetic information is read by a magnetic head provided in a photographic processing apparatus, and the density and color tone of the print are adjusted based on the read magnetic information. In addition, a latent image recording unit using a barcode or the like is provided around the frame, and information such as a frame number recorded in the latent image recording unit is read by an optical sensor provided in the photographic processing device. Conventionally, control of a photographic processing apparatus based on the photographic processing apparatus is also practiced.

[0003]

Conventionally, however, information for each film, such as film sensitivity, has to be input to a photographic processing apparatus by a key operation or the like at the time of processing. It was going to take time.

[0004] Further, it has been considered to clean the film contact portion in the film transport path with a cleaning film. However, in order to clean the film contact portion using this cleaning film in a conventional photographic processing apparatus, An instruction to stop the normal processing operation and to reciprocate the cleaning film on the transport path must be input by a key operation or the like, and the operation is expected to be complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and can save time and effort for inputting information about a film, and can perform a cleaning operation using a cleaning film very easily. It is an object of the present invention to provide a photographic processing apparatus that can perform the processing.

[0006]

In order to achieve the above object, the present invention provides a film cartridge which is removably mounted on a mounting portion provided at one end of a film transport path.
In a photographic processing apparatus in which a film drawn from the film cartridge is transported on the transport path and processed by a photographic processing unit provided in the middle of the transport path, and then the film is rewound into the film cartridge. The mounting portion is provided with a cartridge information sensor that reads information recorded on the surface of the film cartridge, and the transport path is provided with a film information sensor that reads information recorded on the film, and the cartridge information sensor If the interpreted information indicates that the film cartridge contains a cleaning film for cleaning the film contact portion in the transport path, a predetermined cleaning operation using the cleaning film is performed. And then
When rewinding the film on the transport path into the film cartridge, the cartridge ID number read by the cartridge information sensor is compared with the film ID number read by the film information sensor, and if there is a mismatch, an error is displayed. It is what was constituted.

[0007]

In the photographic processing apparatus according to the present invention, when a film cartridge is mounted on the mounting portion, information recorded on the surface of the film cartridge is read by a cartridge information sensor. When the information read by the cartridge information sensor indicates that the film cartridge contains a cleaning film for cleaning the film contact portion in the transport path, the cleaning film was used. A predetermined cleaning operation is performed. When the film is pulled out from the film cartridge onto the transport path, information recorded on the film is read by a film information sensor. When rewinding the film drawn on the transport path into the film cartridge,

Embodiments of the present invention will be described below. 1 is a side view for explaining a main mechanism of a photographic processing apparatus according to an embodiment of the present invention, FIG. 2 is a plan view of FIG. 1, FIG. 3 is a schematic perspective view of FIG. 1, and FIG. FIG. 5 is a plan view of the negative film.

The photographic processing apparatus according to the present embodiment is for producing a print from a negative film.
And a transport path 5 for transporting the negative film 2 having the following from the carry-in port 3 to the carry-out port 4. The transport path 5 includes an exposure unit 6 (an example of a photographic processing unit), a read magnetic head 7, a write magnetic head 8, and An optical sensor 9 is provided.

A transport roller pair 5a is disposed near the carry-in entrance 3 of the transport path 5, and is configured to sandwich and transport the negative film 2. In addition, a transport roller pair 5b similar to this is disposed closer to the carry-in port 3 than the exposure unit 6, and a transport roller pair 5c is disposed closer to the carry-out port 4 than the exposure unit 6.
The conveying roller pairs 5a, 5b, and 5c are synchronously driven to rotate by a motor M. When the motor M is rotated forward, the negative film 2 is sequentially fed from the entrance 3 to the exit 4, and the motor M is rotated in the reverse direction. Then, the negative film 2 is reversely fed from the carry-out port 4 to the carry-in port 3.

A perforation 2b is formed at both ends of each frame 2a on one side of the negative film 2 where the magnetic recording portion 1 is formed. On the other side of the negative film 2, a latent image recording section 10 using, for example, a bar code is formed.

The read magnetic head 7 (film information sensor) reads information recorded on the magnetic recording section 1 of the negative film 2, and the write magnetic head 8 writes information on the magnetic recording section 1. The optical sensor 9 (film information sensor) detects the position of the perforation 2b and reads information recorded in the latent image recording unit 10. Further, the exposure unit 6 irradiates light from a light source (not shown) onto the negative film 2 conveyed onto the exposure stage 6a, and prints photographic paper (not shown) with the light transmitted through the negative film 2. .

The negative film 2 is a film cartridge 1
4. A mounting section 15 for mounting the film cartridge 14 is formed at one end of the transport path 5, and a film winding section 16 is formed at the other end of the transport path 5.
When the film cartridge 14 is mounted on the mounting portion 15,
The negative film 2 is transported on the transport path 5 toward the film winding section 16. further,
The transport roller pair 5a of the transport path 5 and the read magnetic head 7
Between them, a film cleaner 17 for removing dirt on the surface of the negative film 2 is provided.

Below the surface of the film cartridge 14, besides the ID number unique to each cartridge, the manufacturer name of the negative film 2 housed therein, and the film sensitivity (I
Cartridge information recording unit 1 for recording information for each film by a bar code, such as SO100, 400, etc., and the number of photographed films (24, 36, etc.)
8 are formed. When the film cartridge 14 of the mounting section 5 is mounted, the cartridge information recording section 1
A cartridge information sensor 19 (a bar code reader in the present embodiment) is provided at a position facing 8.

When the film cartridge 14 is mounted on the mounting section 5, the information recorded in the cartridge information recording section 18 is read by the cartridge information sensor 19, and the photographic processing apparatus is controlled based on the read information. It is configured as follows.

When the negative film 2 is transported on the transport path 5, an ID number unique to each film recorded in the magnetic recording unit 1 or the latent image recording unit 10 is read, and the magnetic head 7 or the optical sensor 9 reads the ID number. The negative film 2 having been read and subjected to the photographic processing is again put into the film cartridge 14.
When the film is accommodated in the printer, the ID number of the film is compared with the ID number of the cartridge, and if there is a mismatch, the operation is stopped and an error display is performed. Accordingly, even when a large number of negative films 2 are processed at once, the negative films 2 can be surely returned to the film cartridge 14 in which the negative films 2 were originally stored.

Further, the cartridge information recording section 18 of the film cartridge 14 containing a cleaning film (not shown) for cleaning the film contact portion in the transport path 5 indicates that the film cartridge 14 contains the cleaning film. When the cartridge information sensor 19 reads the information shown,
The photographic processing apparatus automatically performs a predetermined cleaning operation that is set in advance by using a cleaning film.

Incidentally, the predetermined cleaning operation means, for example, that normal processing operations such as supply and exposure of photographic paper are stopped, the cleaning film is transported from the film cartridge 14 to the film take-up unit 16, and then the film winding is performed. The cleaning film wound up by the take-up section 16 is transported in the reverse direction and stored in the film cartridge 14. By such a cleaning operation, the transport roller pairs 5a, 5b, 5c, the read magnetic head 7,
Transport path 5 such as write magnetic head 8, optical sensor 9, etc.
The dirt adhering to the film contact portion can be removed.

As the cleaning film, for example, a film in which a urethane film layer is formed on one or both surfaces of a film base, and the dirt on the film contact portion is removed by the adhesive force of the urethane film layer, or a polishing process is performed on one or both surfaces of the film base Is applied to form a relatively coarse matte surface, and the matte surface is used to remove dirt on the film contact portion.

Although a bar code reader is used as the cartridge information sensor in the above embodiment, the cartridge information sensor is not limited to this. For example, information is magnetically recorded on the surface of a film cartridge, and It is also conceivable to provide a magnetic read head and read information with this magnetic read head. Also, a plurality of projections corresponding to the information to be recorded are formed on the surface of the film cartridge, and a detection sensor such as a photoelectric type or a limit switch type for detecting the position and number of the projections is provided on the mounting portion. It is also conceivable to read information by using.

In the above embodiment, a photographic processing apparatus for processing a negative film having a magnetic recording section has been described. However, the photographic processing apparatus is not necessarily required to process a negative film having a magnetic recording section. Further, the film may be a positive film.

Furthermore, in the above-described embodiment, the case where the photographic processing apparatus creates a print from a negative film has been described. However, the photographic processing apparatus is not limited to this, and for example, performs a film developing process. It may be something.

[0023]

As described above, according to the photographic processing apparatus of the present invention, when the film cartridge is mounted on the mounting section, the information recorded on the surface of the film cartridge is replaced with the cartridge information provided on the mounting section. Read by the sensor. If the information read by the cartridge information sensor indicates that the film cartridge contains a cleaning film, a predetermined cleaning operation using the cleaning film is performed. This eliminates the need for inputting information about the film and instructions for the cleaning operation to the photographic processing apparatus by key operation or the like as in the related art, so that the time and effort required for input can be reduced, and the cleaning operation can be performed very easily. it can. When the film is pulled out from the film cartridge onto the transport path, the information recorded on the film is read by a film information sensor provided on the transport path, and when the film is rewound into the film cartridge, the information is stored in the cartridge. The cartridge ID number read by the information sensor is compared with the film ID number read by the film information sensor. If there is a mismatch, an error is displayed. Therefore, the effect that the film can be surely returned to the film cartridge in which the film was originally stored is also obtained.
