Abstract
One end of both pinch roller shafts of a pair of pinch rollers is arranged at the first bearing member, and at the second bearing member the other end is arranged. The first and second bearing members are supported rotatably around a supporting shaft provided in a holder. Hence, the capstan roller can remain tightly in contact with the pinch roller, and the film can be prevented from sliding on the capstan, so that the film can be transported accurately.
Claims14
A film transporting apparatus for reading frames of film images using a film scanner, which transports a developed film at a constant speed by rotating a capstan roller, said developed film being pinched along both outer edges between said capstan roller and a pair of pinch rollers pressed on said capstan roller, wherein:
- one end of both pinch roller shafts of said pinch rollers is arranged at a first bearing member, and the other end of both of said pinch roller shafts is arranged at a second bearing member;
- and
- said first and second bearing members are supported rotatably around a supporting shaft provided in a holder wherein each end of said supporting shaft is coupled to said holder.
A film transport device which transports a film at a constant speed by rotating a capstan roller, said film being pinched between said capstan roller and a pair of pinch rollers pressed on said capstan roller, wherein
- one end of both pinch roller shafts of said pinch rollers is arranged at a first bearing member, and the other end of both of said pinch roller shafts is arranged at a second bearing member;
- said first and second bearing members are supported rotatably around a supporting shaft provided in a holder wherein each end of said supporting shaft is coupled to said holder;
- and
- a clearance is provided between each end of both said pinch roller shafts and each of said first and second bearing members such that said pinch rollers can be parallel to said capstan roller.
A film transport device which transports a film at a constant speed by rotating a capstan roller, said film being pinched between said capstan roller and a pair of pinch rollers pressed on said capstan roller, wherein
- one end of both pinch roller shafts of said pinch rollers is arranged at a first bearing member, and the other end of both of said pinch roller shafts is arranged at a second bearing member;
- said first and second bearing members are supported rotatably around a supporting shaft provided in a holder wherein each end of said supporting shaft is coupled to said holder;
- and
- a clearance is provided between each end of said supporting shaft and each of said first and second bearing members such that said pinch rollers can be parallel to said capstan roller.
A film transporting apparatus for reading frames of film images using a film scanner, which transports developed film at a constant speed by rotating a capstan roller, said developed film being pinched along both outer edges between said capstan roller and a pair of pinch rollers pressed on said capstan roller, wherein:
- one end of both pinch roller shafts of said pinch rollers is arranged at a first bearing member, and the other end of both of said pinch roller shafts is arranged at a second bearing member;
- said first and second bearing members are supported rotatably around a supporting shaft provided in a holder wherein each end of said supporting shaft is coupled to said holder;
- and
- a diameter of said capstan roller is larger than a diameter of said pinch rollers, and a material of said capstan roller is softer than a material of said pinch rollers, so that said capstan roller changes shape by pressure from said pinch rollers such that said pinch rollers inroad into said capstan roller.
