Abstract: In the present invention, two stitch control signals are memorized in each address, one of these stitch control signals is used as an address signal, the other signal is used as a stitch control signal in its address, and this address signal is the next stitch control signal. Therefore, when the next stitch control signal is an address signal of the stitch control signal to be executed then, the discrimination in a data selector becomes fast and the motion for sending the stitch control signals is quickly executed.

Abstract: In the present invention, a timing pulley is moved to a start point position in which a start point switch is switched on or off by a pulse motor, the start point position is memorized in a memory of a control circuit, key codes of selected pattern selection switches are calculated, a driving step number of the pulse motor is calculated by cam position data of a selected pattern obtained by the key codes, the cam position data being previously memorized in a memory, and position data of pattern cam selected in the present time, the position data being memorized in a random access memory and a cam-follower is moved to the position of the selected pattern cam by driving the pulse motor.
