Abstract

PURPOSE: To accomplish a change in the acceleration and deceleration of the paper feeding by means of a control circuit of the servo motor for driving the paper feeding tractor and a limit value change-over means of the current.
CONSTITUTION: When the switch 15 is put to the position MORMAL, with the setting of the paper feed drive signal FEED-PI, the acceleration/constant speed control circuit 8 is energized to drive the servo motor 4. The acceleration current is limited by the current limiting circuit 14 to make the paper feed acceleration match for the limited value thus obtained. When the SLOW paper feed is selected, the paper feed speed change-over switch 15 is changed over to the position SLOW from the position MORMAL. At this point, with the output of the memory circuit 16, the limit value of the drive current to the servo motor 4 to be selected by the current limited circuit 14 is switched to a smaller one and the corresponding output is given to the acceleration/constant speed control circuit 8 and the deceleration control circuit 11 thereby reducing the acceleration and the deceleration of the paper feed.
