Abstract
A sheet feeding mechanism includes a feeding path, at least one card feeding roller mounted to the feeding path, at least one paper feeding roller coaxial with the at least one card feeding roller, at least one card idle roller contacting with the at least one card feeding roller, at least one paper idle roller contacting with the at least one paper feeding roller, at least one elastic unit connected to the feeding path, and a stroke limiting unit. The at least one elastic unit is fastened to the feeding path. The at least one elastic unit has a stretching stroke. The stroke limiting unit controllably shortens the stretching stroke.
Claims8
A sheet feeding mechanism, comprising:
- a feeding path;
- at least one card feeding roller mounted to the feeding path;
- at least one paper feeding roller coaxial with the at least one card feeding roller;
- at least one card idle roller contacting with the at least one card feeding roller;
- at least one paper idle roller contacting with the at least one paper feeding roller;
- at least one elastic unit connected to one side of the at least one card idle roller, the at least one elastic unit being fastened to one side of the feeding path, the at least one elastic unit having a stretching stroke;
- and
- a stroke limiting unit controllably shortening the stretching stroke,
- wherein when the stretching stroke is without being shortened by the stroke limiting unit, the at least one card idle roller is located in the stretching stroke, when the stretching stroke is shortened by the stroke limiting unit, the at least one card idle roller is located outside a range of the stretching stroke.
A sheet feeding mechanism, comprising:
- a feeding path;
- two groups of card feeding rollers mounted to the feeding path;
- two groups of paper feeding rollers, each group of the paper feeding rollers being coaxial with one group of the card feeding rollers;
- two groups of card idle rollers in contact with the two groups of the card feeding rollers, respectively;
- two groups of paper idle rollers in contact with the two groups of the paper feeding rollers, respectively;
- two groups of elastic units fastened to an upper side of the feeding path, each card idle roller being connected with one elastic unit, each elastic unit having a stretching stroke;
- and
- a stroke limiting unit controllably shortening the stretching stroke,
- wherein when the stretching stroke of each elastic unit is shortened, the two groups of the card idle rollers exceed a range of the stretching stroke, when the stretching stroke is lengthened, the two groups of the card idle rollers are in the range of the stretching stroke.
A sheet feeding mechanism, comprising:
- a feeding path;
- two groups of card feeding rollers mounted to the feeding path;
- two groups of paper feeding rollers, each group of the paper feeding rollers being coaxial with one group of the card feeding rollers;
- two groups of card idle rollers in contact with the two groups of the card feeding rollers, respectively, each group of the card idle rollers being mounted around a pivoting shaft;
- two groups of paper idle rollers in contact with the two groups of the paper feeding rollers, respectively;
- two groups of elastic units fastened to an upper side of the feeding path, each card idle roller being connected with one elastic unit, each elastic unit including a sliding pin, each elastic unit having a stretching stroke;
- an orienting unit fastened to one side of a top of the feeding path, the orienting unit having two groups of orienting slots, the two groups of the orienting slots being disposed towards free ends of the pivoting shafts of the two groups of the card idle rollers, the sliding pins of the two groups of the elastic units being slidably positioned in the two groups of the orienting slots of the orienting unit;
- and
- a stroke limiting unit controllably shortening the stretching stroke,
- wherein when the stretching stroke of each elastic unit is shortened, the two groups of the card idle rollers exceed a range of the stretching stroke, when the stretching stroke is lengthened, the two groups of the card idle rollers are in the range of the stretching stroke.
