Here, when the negative film 12 conveyed through the conveying path 38 is fed into the film accommodating portion 34, first, the leading end of the negative film 12 is wound by the guide plate 128 with the guide roller 52A provided on the guide plate 128. It is guided between the shaft 50 and is sandwiched between the guide roller 52A and the winding shaft 50.

Thereafter, the leading end of the negative film 12 moves while receiving a frictional force generated between the negative film 12 and the peripheral surface of the winding shaft 50, and is immediately guided by the guide plate 140 to guide the guide plate 14.
It is nipped between the guide roller 52B at the end of 0 and the winding shaft 50.

The leading end of the negative film 12 wound around the winding shaft 50 in this manner is restrained by the winding shaft 50 by the intermediate portion of the negative film 12 itself which is newly fed into the film accommodating section 34. The winding shaft 50 is surely wound up.

Further, after the negative film 12 drawn out from the cartridge 20 is once wound up and contained in the film accommodating portion 34, the motors 40 and 44 are reversely rotated to pull out the negative film 12 from the film accommodating portion 34, Frame feed transport. At this time, the negative film 12
The image recorded in each image frame 16A is printed on photographic paper. Further, when the negative film 12 is frame-fed and conveyed, the recording head 62 of the magnetic head unit 58 writes magnetic information to the magnetic track 26 of the negative film 12.

Furthermore, since the dust removing rollers 210 and 220 rotate during this frame-feeding conveyance, the negative film 12 is not subjected to an extra load such as tension.

Then, the negative film 12 having the magnetic information written on the magnetic track 26 is loaded into the cartridge loading section 32.
The spool film 22 is wound up and the negative film 12 is accommodated in the cartridge 20.

On the other hand, when the negative film 12 is conveyed as described above, the height position, which is the installation position of the dust removing roller 220 of the pair of dust removing rollers 210, 220 with respect to the negative film 12, can be adjusted by adjusting the screwing amount. Since the positioning bolt 232 is provided, the contact amount of the dust removing rollers 210 and 220 with respect to the negative film 12 can be easily adjusted, and the dust adhered to the negative film 12 can be reliably removed and the negative film 12 can be stabilized. It is possible to secure the transport that has been completed.

The present embodiment shows an example of the film carrier to which the present invention is applied, and does not limit the constitution of the present invention, and the present invention can have various constitutions.

For example, in the above embodiment, the dust removing rollers are arranged on the pedestal 30 and the cover 36, respectively.
If only one side of the negative film 12 needs to be cleaned, the pedestal 3
It may be arranged on only one of the 0 and the cover 36.

Further, in the above-described embodiment, the clutch material is the one-way clutch, but any other material having a similar function may be used, for example, a structure in which the one-way clutch is built inside the dust removing roller. May be Further, the dust removing roller may be configured to rotate only in the reverse rotation of the above embodiment.

On the other hand, in the above embodiment, the position adjusting mechanism composed of the positioning bolt 232, the coil spring 236, the coil spring 242 and the like is adopted to adjust the installation position of the dust removing roller with respect to the negative film. A mechanism using another known gear or the like may be adopted.
