PURPOSE:To reduce the power and to lessen the tension of a belt by arranging stoppers thinner than slide plates in the belt moving direction on the support surface of the belt, thereby to displace the slide plates between the stoppers in a belt conveyer apparatus with a slide plate. CONSTITUTION:When a belt 3 starts to move, slide plates 9 are displaced on a support surface 2 having a small coefficient of friction with the belt 3 having a large coefficient of friction with the slide plates 9. At that time, the frictional force acting upon the belt 3 is smaller than the frictional force produced by the belt 3 starting to move on the slide plates 9. Accordingly, the starting power of a conveyer is lessened, and the tension acting upon the belt 3 is reduced. When the slide plates 9 are displaced by a distance L, the slide plates 9 are brought into contact with the stopper 10 to be stopped. At this time, the belt 3 is decreased in speed to a certain degree, so that the belt tension is reduced until the steady state. Thus, the power and belt tension can be reduced. |
