Abstract
The automatic sewing machine comprises a sewing head mounted on a table, cloth clamping plates driven by pulse motors in X and Y axis directions of rectangular coordinates on the table, and a pulse generator for applying driving pulses to the pulse motors. The control system of the sewing machine comprises a PROM including a first code region representing the type of control and a second region for storing data required to store data utilized to perform respective sewing steps, a sewing machine operation panel unit including a control signal generator for controlling the operation of the sewing machine, a bus line between the PROM and the sewing machine operation panel unit, a RAM including a first memory region for storing the pulse motor drive pulses and the control signals, and a second region for storing the data corresponding to an address count value for designating an address of the PROM and the type of control and the data in the second code region, a central processor unit, and PROM/ROM connected to the PROM, RAM and the central processor unit through the bus line. The PROM/ROM contains a program of various instruction groups for sequentially forming operation instructions…
