Abstract

PURPOSE:To decrease the moving time of an article without being affected by the quantity of the aritcle moved by simple circuit constitution by changing over the drive of the motor to gradual decrease speed from gradual increase speed by the quantity of the article moved. CONSTITUTION:The set value of a necessary movement quantity setting circuit 4 is inputted to a movement quantity converting circuit 5, and the quantity of movement is converted into the number of steps of the step-motor 9. One branch of the output is inputted to a half movement quantity circuit 6 decreasing the number of the step to half, and the other branch is inputted to a subtraction circuit 1. Step signals driving the motor, the output of a motor drive circit 8, are futher inputted to the circuit 1. One branch of the output of the circuit 1 is inputted to a comparison circuit 3-1 together with the output of the circuit 6, and the other branch is inputted to a comparison circuit 3-2 together with the quantity of movement 2 required for stoppage at gradual decrease speed not the maximum speed. The output of both comparison circuits is inputted to the motor drive circuit 8 through an or circuit 7.
