摘要： [Purpose] To obtain a sewing machine comprising a device with which it is possible to easily perform a threading operation in which a needle thread is inserted into the needle hole of the sewing machine needle, wherein the sewing machine comprises a threading device configured so that the needle thread does not drop onto or coil around an operation part (operation part) of the operation lever of the threading device when a thread-hooking operation is completed before insertion of the needle thread. [Configuration] The present invention comprises: a needle bar 52; a threading shaft 53; a thread-holding tool 71; a threading tool 72 provided at the bottom end of the threading shaft 53; an operation lever 4 that has an operation part 41 and moves the threading shaft 53 up and down and rotates the threading shaft in the circumferential direction; and a cutting tool 93 for the needle thread n. The present invention is configured such that a needle thread guide member A, in which an inclined part 1 is formed that guides the needle thread n from the thread-holding tool 71 to the cutting tool 93, is provided between the thread-holding tool 71 and the cutting tool 93, and the inclined part of the needle thread guide member A guides the needle thread n that has been cut by the cutting tool out of the operation range of the operation lever 4.

摘要： A sewing control device includes in a sewing machine having upper feed function a control device which controls feed of an object to be sewn. A lower feed amount setting motor sets a feed amount of a lower feed dog and an upper feed amount change motor changes a feed amount of an upper feed dog. A feed execution range, in which the feed of the object to be sewn is executed by an appropriate feed amount while the object to be sewn is sandwiched between the lower feed dog and the upper feed dog, and a feed non-execution range, in which the feed of the object to be sewn is not executed in a state in which the feed dogs do not act on the object to be sewn, are present. The feed amount of the upper feed dog can be changed only in the feed non-execution range during sewing.
