(1) Compared to the conventional drive belt/driven belt clamping conveyance system, the number of belts can be reduced to less than half, and since the driven roller means is rotatable as a driven system, the driving torque can be halved. . Reducing the driving torque also produces the effects of reducing the capacity of the motor, reducing power consumption, and improving reliability such as vibration and noise.

(2) Parts such as belts, pulleys, shafts, and bearings, which were required in the belt conveyance system, are integrated by the driven roller means and are no longer necessary, resulting in a reduction in the number of parts and manufacturing cost. At the same time, whereas it was difficult to reduce the minimum diameter of the pulley in a belt conveyance system due to its functionality, this conveyance system has fewer functional restrictions and can be made considerably thinner than conventional conveyance systems. This has the effect of making it smaller.

(3) In the conventional driving belt/driven belt clamping conveyance system, the conveyance between the pulleys on the same conveyance surface side is carried by using an opposing belt as a guide. For this reason, there were constraints on conveyance, such as the pulley setting position, but in the single-pinching conveyance method, the connected roller row plays the role of a guide, so restrictions on the belt pulley setting position can be reduced. .
