Winding method and device for photo film and photo film carrier

A winding device for winding a transported photo film about a winder shaft, comprising:

• a tightening guide disposed close to a lapping position defined where a leading end of said photo film becomes lapped on said photo film after making one rotation, said tightening guide pushing said photo film toward a peripheral surface of said winder shaft and winding said photo film so that said photo film is fit on said winder shaft;
• a winder shaft driving unit for rotating said winder shaft at a peripheral speed predetermined to be higher than a transporting speed of said photo film, to remove looseness from said leading end at said lapping position about said winder shaft according to a difference of said speeds in passage of said tightening guide;
• and
• a leading end guide, disposed away from said peripheral surface of said winder shaft, for guiding said leading end of said photo film toward said tightening guide;
• wherein a portion of said photo film near to said leading end, which has not reached said tightening guide, is fit on said winder shaft before said leading end becomes lapped.

A winding method of winding photo film, comprising:

• winding said photo film so that said photo film is fit on a winder shaft using a tightening guide including
• a guide plate,
• a first press roller,
• a first groove, formed in said guide plate, extended in an axial direction with respect to the winder shaft, for supporting the first press roller in a rotatable manner, wherein at least a portion of said first press roller protrudes from said first groove, and
• a bias member that biases said guide plate toward said winder shaft, to press said photo film toward a peripheral surface of said winder shaft, and
• winding a leading end of said photo film so that the leading end of the photo film becomes lapped on said photo film after making one rotation about said winder shaft after winding said photo film in a fitted manner on said winder shaft.

• a bias member that biases said guide plate toward said winder shaft, to press said photo film toward the peripheral surface of said winder shaft;
• a winder shaft driving unit for rotating said winder shaft at a peripheral speed predetermined higher than a transporting speed of said photo film, to remove looseness from said leading end at said lapping position about said winder shaft according to a difference of said speeds in passage of said tightening guide;
• and
• a leading end guide, disposed away from said peripheral surface of said winder shaft, for guiding said leading end of said photo film toward said tightening guide.

A winding method of winding photo film, comprising a step of:

• in winding said photo film about a winder shaft, winding said photo film so that said photo film is fit on said winder shaft before a leading end of said photo film becomes lapped on said photo film after making one rotation about said winder shaft;
• wherein a tightening guide is used for winding said photo film about said winder shaft, and an exit of said tightening guide for said photo film is disposed close to a lapping position defined where said leading end of said photo film becomes lapped on said photo film after making one rotation around the winder shaft;
• and
• a peripheral speed of said winder shaft is predetermined to be higher than a transporting speed of said photo film, to remove looseness from said leading end at said lapping position about said winder shaft according to a difference of said speeds in passage of said tightening guide,
• wherein a leading end guide for said photo film is disposed away from a peripheral surface of said winder shaft, and guides said leading end of said photo film toward said tightening guide,
• wherein said winder shaft includes a core, and a frictional lining member for capturing said photo film frictionally, said frictional lining member having a tubular shape for covering said core, and
• wherein said tightening guide includes:
• a guide plate;
• a bias member for biasing said guide plate toward said winder shaft, to press said photo film;
• and a guide surface formed in said guide plate, said guide surface being an approximately circular arc concentric with said winder shaft except at an inlet portion.
