DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic film reading / recording apparatus in a photographic processing apparatus.

[0002]

2. Description of the Related Art In recent years, color films in which a magnetic layer is applied to a film have been devised. When performing printing operation using this film, it is necessary to record and read the photographing information recorded at the time of imaging by the camera, from one of the information has been printed on any kind of conditions upon printing on the film. In order to read this magnetic information, it is necessary to bring the film into close contact with the magnetic head.
Equipment was being developed.

A method / apparatus for bringing a film A into close contact with a magnetic head c by a transport roller unit b having a compression spring a as shown in FIG. Further, a crimping guide d having an upper part formed in the tip shape of the magnetic head c as shown in FIG.
Method and apparatus using. Further, as shown in FIG. 9, a method / apparatus in which the pressing pad e is pressed by the pressing leaf spring f to bring the film A into close contact with the magnetic head c. Further, as shown in FIG. 10, there has been a method / apparatus using a pressing / guiding member g using only a leaf spring. Further, as shown in FIG. 11, the endless belt h is rotated by the driving device i, and the film A is rotated.
There is a method / apparatus and the like for bringing the magnetic head into close contact with the magnetic head c.

[0004]

However, the conventional method and apparatus as described above have the following problems.
That is, as shown in FIG.
When the sheet is conveyed to the side by a roller or the like, the contact area is small and reading becomes unstable. Further, as shown in FIG. 8, it is difficult to process with a guide conforming to the head shape of the magnetic head c, and the adhesion is incomplete. Further, as shown in FIG. 9, when the film is inserted into the pad, the film cannot pass unless the pressure contact is released. Further, in the case of using a plate spring as shown in FIG. 10, there are various problems such as a high conveying force and a resistance when the film passes.

Further, in the case of using a belt as shown in FIG. 11, a driving source for rotating the belt is required, and in order to drive the belt without slipping, it is necessary to increase the tension. There is a problem with passing the film between the magnetic head and the belt. Further, when the belt is driven, the feeding speed of the film is different from that of the other portions due to a belt thickness error or the like, and there is a possibility that slack or the like occurs.

[0006] The present invention has been developed in view of the above points, and an object of the present invention is to bring a film with a magnetic recording portion into close contact with a magnetic head with appropriate strength and to record magnetic recording information on the film. An object of the present invention is to provide a magnetic reading / recording device for a film in a photographic processing device capable of reading or writing data more accurately.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In a photographic processing apparatus provided with a magnetic head for reading or writing magnetic recording information of a film with a magnetic recording portion conveyed by a conveying roller, FIGS.
(And FIGS. 5 to 6) show a first embodiment according to the present invention, wherein 1 is a pair of transport rollers for transporting a film A. A magnetic head 3 is disposed between the two pairs of transport rollers 1, and an endless belt 4 is rotatably disposed at a position facing the magnetic head 3.

The rotatably provided endless belt 4 is rectangularly and rotatably stretched by supporting rollers 5, 5 and flange rollers 6, 6 disposed at four corners. A tension roller 7 is provided between the flange rollers 6 and 6. The above transport rollers 1,
Magnetic head 3, support rollers 5, 5, flange roller 6,
The tension roller 6 and the tension roller 7 are provided on the holding member 8.

The tension roller 7 is provided on the holding member 8 so as to be vertically movable.
The rear part 7a is locked by a spring 10 whose one end is locked by a locking pin 9 provided on the back surface of the magnetic head 3, and the tension roller 7 is constantly pulled toward the magnetic head 3. Thus, the endless belt 4 is stretched with a desired tension.

The endless belt 4 stretched as described above is supported by the supporting rollers 5, 5, the flange rollers 6, 6, and the tension roller 7 so as to be freely rotatable. When the film A is conveyed so as to be sandwiched between the belt 4 and the magnetic head 3, the endless belt 4 rotates in the same direction as the film A with the conveyance of the film A by the action of the conveyance roller 1, so that it is more smooth. Film A
Can be transported. Therefore, magnetic information can be accurately read (or written) from the film.

Further, the tension of the endless belt 4 can also be optionally Adjusts the conveying force of the endless belt A which contacts through the film A to <br/> magnetic head 2 <br/> regulatory can do. It is preferable to use a resin film or rubber belt for the endless belt A.

FIGS. 3 and 4 (and FIGS. 5 and 6) show a second embodiment according to the present invention. In this embodiment, the endless belt 4 is stretched around the outer periphery of a belt holding block 11, and FIG. It is to be able to tension adjustment clause freely by the tension roller 7.

In both the first embodiment and the second embodiment, by moving the tension roller 7, the endless belt 4 can be loosened and easily removed. Further, the film A can be pressed by the endless belt 4 to a position where the magnetic head 3 is pressed slightly below the tangent line at the apex of the magnetic head 3, and the contact surface between the magnetic head 3 and the film A can be made large.

[0018]

As is apparent from the above description, according to the present invention, the film with the magnetic recording portion conveyed by the conveying roller is adhered to the magnetic head by an endless belt rotatable in the moving direction of the film. Since it is transported, magnetic information can be accurately read from the film. Also, magnetic information can be accurately written on the film. Further, since the endless belt is rotatable in the same direction as the moving direction of the film, resistance when the film passes through the magnetic head can be reduced. Further, the endless belt can be adhered to the shape of the magnetic head, and the adhesion of the film does not decrease even if the pressing force (pinching force) on the film is reduced. Further tension low
The tension of the endless belt by adjusting
Can be adjusted.

Further, in the apparatus provided with the fixed endless belt, the film with the magnetic recording portion can be pressed against the magnetic head with appropriate strength without providing a driving device for rotating the endless belt, and the magnetic information can be accurately read from the film. Can be read (or written). Also,
The endless belt tension can be adjusted by adjusting the roller.
The power can be adjusted easily.
