A belt conveyor having two rollers supported at opposite ends of a support frame and a belt stretched between the rollers, in which a cylinder having an operating rod reciprocatable in a moving direction of the belt is mounted on the support frame; a drum including a one way clutch mechanism therein and having a sprocket wheel fixed therearound is fitted around a transmission shaft integral with one of the rollers; a chain is wound around the sprocket wheel mounted around the drum including the one way clutch mechanism therein; and the chain is connected to the operating rod of the cylinder. When the operating rod of the cylinder reciprocates, the chain is reciprocated by the operating rod. This reciprocatingly rotates the sprocket wheel mounted on the drum in which the one way clutch mechanism is installed. The rotation in a predetermined direction is transmitted, through the one way clutch mechanism, to the transmission shaft of the roller around which the belt is wound. The roller then rotated intermittently in one direction and the belt is fed intermittently.
