Bank note conveying apparatus

A bank note conveying apparatus which conveys bank notes along a conveying path in a conveying direction, comprising:

• a path forming member forming the conveying path in a width larger than that of a bank note;
• said path forming member having a widthwise position guide provided along one widthwise end of the conveying path for arranging positions of the bank notes in a widthwise direction of the conveying path;
• a first pinching roller mechanism and a second pinching roller mechanism for sending the bank notes in the conveying path in the conveying direction;
• a bank note widthwise arranging mechanism for directing the bank notes in the conveying path toward the widthwise position guide allowing conveyance of the bank notes in the conveying direction;
• and
• an interlocking mechanism for driving said first pinching roller mechanism and said second pinching roller mechanism in conjunction with said bank note widthwise arranging mechanism;
• said first pinching roller mechanism and said second pinching roller mechanism respectively including:
• a driving roller for conveying the bank notes in the conveying direction and being contactable with either one of two faces of the bank notes;
• a driving rotating shaft for said driving roller which extends in a direction perpendicular to the conveying direction;
• a driven roller which rotates in accordance with the movement of the bank note in the conveying path, said driven roller being provided opposite said driving roller and being contactable with another face of the bank notes;
• a driven rotating shaft for said driven roller which extends in a direction perpendicular to the conveying direction;
• and
• a rotating shaft driving pulley which is fixed to said driving rotating shaft;
• said bank note widthwise arranging mechanism including a widthwise arranging endless belt disposed between said driving roller of said first pinching roller mechanism and said driving roller of said second pinching roller mechanism, and disposed in a position where it is contactable with either one of the faces of the bank notes and provided slantingly with respect to the conveying direction for directing the bank notes toward said widthwise position guide while feeding the bank notes in the conveying direction;
• a driving pulley and a driven pulley over which said widthwise arranging endless belt is looped;
• a driving rotating shaft of said driving pulley provided slantingly with respect to the conveying direction and which extends in a direction perpendicular to said widthwise arranging endless belt;
• a driven rotating shaft of said driven pulley being disposed parallel to said driving rotating shaft;
• a rotating shaft driving pulley fixed on said driving rotating shaft;
• a rotating body disposed at a position where it is contactable with the face of the bank notes opposite to that contacted by said endless belt and having a frictional force against the bank notes which is smaller than that between the widthwise arranging endless belt and the bank notes;
• and
• a rotating body supporting mechanism which rotatably supports the rotating body;
• said driving roller of said first pinching roller mechanism and said driving roller of said second pinching roller mechanism being arranged so that the distance therebetween is longer than the longitudinal length of the bank notes;
• and
• said driving roller of said first pinching roller mechanism and said rotating body of said bank note widthwise arranging mechanism being arranged, and said driving roller of said second pinching roller mechanism and said rotating body of said bank note widthwise arranging mechanism being arranged, such that the respective distance therebetween is shorter than the longitudinal length of the bank notes;
• said interlocking mechanism including:
• an interlocking pulley which is fixed to one of said driving rotating shafts of said first pinching roller mechanism and said second pinching roller mechanism;
• a first interlocking endless belt looped over said interlocking pulley and said rotating shaft driving pulley of said bank note widthwise arranging mechanism;
• a second interlocking endless belt looped over said rotating shaft driving pulley of said first pinching roller mechanism and said rotating shaft driving pulley of said second pinching roller mechanism;
• and
• a shaft rotating mechanism for rotating one of said driving rotating shafts of said first pinching roller mechanism and said second pinching roller mechanism.
