PROBLEM TO BE SOLVED: To provide an inexpensive transfusion device provided with a driving mechanism capable of accurately detecting and controlling the movement of a sucker. SOLUTION: In this transfusion device, by using the motor driving circuit of a pulse start-stop type for performing the driving commands of the moving amount and speed, etc., of a motor 5 by pulses and arranging an incremental linear encoder in a feed shaft direction, the moving performance of a carriage part 8 for the sucker 15 is directly monitored and the correlation of a move command and a feed performance is detected. Further, by providing an established position detection sensor 19 on a part where an absolute position is established beforehand, and by storing/resetting the counter by the output of the sensor generated by the movement of the carriage part 8 and starting the counting of the move command amount for which the move amount per pulse is established beforehand, the absolute position of the sucker 15 is recognized. |
