[0001]

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

[0002]

2. Description of the Related Art Recently, a color film in which a magnetic layer is applied to a film has been devised. When performing a printing operation using this film, it is necessary to read the shooting information recorded by the camera at the time of shooting and record the information on the printing conditions under which the film was printed. In order to read this magnetic information, it is necessary to bring the film into close contact with the magnetic head, and various methods and devices have been developed so far.

A method / apparatus for bringing the film A into close contact with the magnetic head c by a conveying roller unit b having a pressure spring a as shown in FIG. 7, for example. Further, a pressure-bonding guide d having an upper portion formed on the tip shape of the magnetic head c as shown in FIG.

Further, as shown in FIG. 10, there is a method / apparatus using a pressing / guide member g only by a leaf spring. Further, as shown in FIG. 11, the endless belt h is rotated by the driving device i to move the film A
There was a method and a device for bringing the magnetic head c into close contact with the magnetic head c.

[0004]

However, the above-mentioned conventional methods and apparatuses have the following problems.
That is, as shown in FIG.
If it is conveyed to the side by a roller or the like, the contact area is small and the reading becomes unstable. Further, as shown in FIG. 8, it is difficult to process with a guide that matches the head shape of the magnetic head c, and the contact is incomplete. Further, in the case of a pad-like material as shown in FIG. 9, the film cannot pass unless pressure contact is released when the film is inserted. Further, as shown in FIG. 10, a plate spring is used, which has 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 tension. There are problems in passing the film between the magnetic head and the belt. Further, when the belt is driven, the film feeding speed may be different from other portions due to a belt thickness error or the like, and sagging may occur.

The present invention has been developed in view of the above points, and an object of the present invention is to attach a magnetic recording portion-attached film to a magnetic head with appropriate strength, and to provide magnetic recording information on this film. It is an object of the present invention to provide a magnetic film reading / recording device for a photographic processing device, which enables more accurate reading or writing.

[0007]

In order to effectively achieve the above object, the present invention has the following structure. That is, 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, while sandwiching the film between the magnetic head and a rotatably provided endless belt. This is a structure that can be transported.

Further, 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 which is conveyed by a conveying roller, an endless belt which fixes the film at a predetermined position with the magnetic head is used. It is configured so that it can be conveyed while being sandwiched.

[0009]

As described above, in the structure described in claim 1, the film with the magnetic recording portion conveyed by the conveying roller is brought into close contact with the magnetic head by the endless belt which is rotatable in the same direction as the moving direction of the film. While being conveyed, the magnetic information can be accurately read (or written) from the film. Further, as described above, since the endless belt can rotate in the same direction as the moving direction of the film, it is possible to reduce the resistance when passing through the film. Further, since the endless belt can be adhered in conformity with the shape of the magnetic head, the adhesion of the film does not deteriorate even if the pressing force (sandwiching force) against the film is reduced.

According to the second aspect of the present invention, the film with the magnetic recording portion can be appropriately pressed against the magnetic head without providing a driving device for rotating the endless belt, and the magnetic information can be accurately read from the film. (Or write)

Embodiments of the present invention will be described below with reference to FIGS. 1 to 2 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.
(And FIGS. 5-6) shows 1st Example which concerns on this invention, 1 is 2 pairs of conveyance rollers which convey the film A. As shown in FIG. A magnetic head 3 is disposed between the two pairs of conveying 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 rotatably stretched in a rectangular shape by support rollers 5 and 5 and flange rollers 6 and 6 arranged at four corners. A tension roller 7 is arranged between the flange rollers 6 and 6. The transport rollers 1,
Magnetic head 3, support rollers 5, 5, flange roller 6,
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, and
The rear portion 7a is locked by a spring 10 having one end locked by a locking pin 9 provided on the back surface of the tension roller 7, and the tension roller 7 is constantly pulled toward the magnetic head 3. As a result, the above-mentioned endless belt 4 is stretched with a desired tension.

The endless belt 4 stretched as described above is rotatably supported by the support rollers 5, 5, the flange rollers 6, 6 and the tension roller 7, so that the film A is the endless belt. When the film A is conveyed while being sandwiched between the belt 4 and the magnetic head 3, the endless belt 4 also rotates in the same direction as the film A along with the conveyance of the film A by the action of the conveying roller 1, which makes the film smoother. To film A
Can be transported. Therefore, the magnetic information can be accurately read (or written) from the film.

Further, the amount of tension of the endless belt 4 can be arbitrarily adjusted, and the conveying force of the endless belt A that contacts the magnetic head 2 can be adjusted. Further, it is preferable to use a resin film or rubber belt for the endless belt A.

FIGS. 3 to 4 (and FIGS. 5 to 6) show a second embodiment according to the present invention. In this embodiment, the endless belt 4 is stretched around the outer circumference of the belt holding block 11. The tension roller 7 allows the tension to be adjusted freely.

Further, the film A can be pressed by the endless belt 4 to a position slightly pushed in from the tangent line of 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 brought into close contact with the magnetic head by the endless belt rotatable in the moving direction of the film. Since it is transported, the magnetic information can be accurately read from the film. Also, the magnetic information can be accurately written on the film. Further, since the endless belt can rotate in the same direction as the moving direction of the film, the resistance when the film passes the magnetic head can be reduced. Furthermore, the endless belt can be adhered in conformity with the shape of the magnetic head, and the adhesion of the film does not deteriorate even if the pressing force (sandwiching force) on the film is reduced.

Further, in the device provided with the fixed endless belt, the film with the magnetic recording portion can be appropriately pressed against the magnetic head without providing a drive device for rotating the endless belt, and the magnetic information can be accurately obtained from the film. It can be read (or written).
