PURPOSE: To provide the title method so designed that a fixing device on a frame fitted with an output circuit and a solenoid is detached and the solenoid is rotated downward, through its gravitational force, around supporting pins, thereby facilitating the inspection, repair, etc., for solenoid failures and whether the solenoid is actuated favorably or not.
CONSTITUTION: A solenoid frame 3 fitted with an output circuit 1 and a soienoid 2 is equipped with supporting pins 4, 5 free to rotate, and the frame 3 and a support 10 are set up at their normal actuation positions using a fixing device 12. When the fixing device is detached, the frame is rotated downward away from a needle selection frame 6, through its own weight, around the supporting pins, and when the needle selection frame is lifted, a projection 7 is disengaged from a second projection 8, thereby facilitating the detachment of the solenoid.
