Claims

[Scope of claim for utility model registration] A throat plate with a hole opening upward and downward, a presser foot that is fixed to the lower end of the presser bar and faces above the hole in the throat plate and receives an elastic force that presses against the upper surface of the throat plate, and a needle. A light emitting body is fixed to the sewing machine frame or table horizontally away from the hole in the plate and is capable of emitting light. A photoreceptor that generates a light reception signal in response to light reception and a light blocking signal in response to light blocking, and a light emitting body that guides the light from the light emitter to the hole in the needle plate and irradiates it upward, causing reflection on the entire bottom surface of the presser foot. an optical path guide means fixed to the lower surface of the throat plate with an optical fiber interposed between the light emitter and the light receiver and the hole in the throat plate so as to guide the light downward from the hole in the throat plate and enter the light receptor; and a light blocking signal. or a control circuit for electrically controlling the starting/stopping of the sewing machine, thread trimming, reversal of the feed direction, etc. in relation to the received light signal; and a control device for a sewing machine.
