An endless conveyor belt, equipped with module carriers combined with two stepper motors M1 and M2, a differential gear and four deflection rollers D1 to D4, permits testing four memory modules in a single cycle, while depositing four different sorts of modules. In other words, it permits performing four different steps without any motion occurring at the test station. The conveyor belt, equipped with module carriers, is loaded with memory modules at the loading station. The step width corresponds to the position of the carriers on the belt. Movement is controlled by optical sensors. The step width during loading is identical for motors M1 and M2. The differential gear does not change its position.
