PURPOSE:To allow a device to cost less by changing materials of both pulleys and conveyor belts in such a way that both sides of the belt have the same friction coefficient. CONSTITUTION:A pulley 2 which is installed on a pulley shaft 1, is composed of a rubber roller. And conveyor belts 3 and 4 which are engaged with the pulley 2, are composed of cloth belts of low friction coefficient. This configuration allows friction coefficient to become high at the pulley side surface of the conveyor belts 3 and 4 permitting the rotation of the pulley 3 to be accurately transmitted to the conveyor belts 3 and 4. Here, as friction between the belt surfaces can be reduced, it is possible that leafs and the like can be stably conveyed. And as the belt, both sides of which have the same friction coefficient, can be used, the device is allowed to cost less.
