PURPOSE:To permit the stable sending of a medium in a printing mechanism used in a transactional (or supply) operator such as cash dispensor by using a tractor mechanism of paper sending system. CONSTITUTION:A belt pin 22 is engaged with sprocket pulleys 18 and 21 to form the paper sending mechanism of a tractor structure. Since the belt pin 22 is engaged with the perforation 6 of a paper 1 at many positions, the sending accuracy of paper is raised. Also, a guide plate 7 is integrated with a tractor 16 and thereby the positioning of the belt pin 22 and the perforation 6 of the paper is made easier. A push plate 9 is extended to the upside of the tractor 16 and faced the guide plate 7 to prevent the dislocation of the paper 1 from the belt pin 22. When the push plate-holding shaft 14 is lifted up at an opposite fulcrum 15 as the center by facing the setting direction (J) of paper, the push plate 9 is opened and the truck 16 having the guide plate 7 and the belt pin 22 appears. The paper 1 is rightly engaged with the belt pins 22 on both sides and the push plate-holding shaft 14 is restored to its original position to complete the setting of the paper 1. |
