Claims

[Scope of utility model registration request]

(1) An operating body that can be operated by hand, a switch that operates by operating the operating body to drive the motor, a clutch mechanism that can transmit or cut off the power of the motor to the main shaft, and a switch that operates by operating the operating body to drive the motor. A stopping mechanism associated with a clutch mechanism is provided to stop the main shaft at a fixed position, and the main shaft is driven by the operation of an operating body, and the main shaft is stopped at a fixed position after performing the required work in that specific rotational phase section. i) A fixed position stopping device for a sewing machine, characterized in that the sewing machine is provided with a blocking means for blocking the action of the stopping mechanism in a specific rotational phase section of the main shaft that performs a required work.

(2) The clutch mechanism has a coiled spring that is loosely fitted into the main shaft and a pulley that rotates in conjunction with the motor around the main shaft, and whose one end is connected to the main shaft, and the stop mechanism is loosely fitted into the spring of the clutch mechanism. When connected to the other end, a regulating body is provided with a regulating part that protrudes from the outer periphery of the regulating body, and an operating body that is always located outside the rotation path of the regulating part of the regulating body and has an elastic acting force directed toward the regulating body. 1. A billing stop device comprising an integrated stopper that enters into the rotation path of the regulating portion when operated.
