20150045939 | STICHWORK STATUS CHECKING SYSTEM, STITCHWORK STATUS CHECKING APPARATUS, STITCHWORK STATUS CHECKING METHOD AND STITCHWORK STATUS CHECKING PROGRAM - A stitchwork status checking apparatus includes a stitchwork data receiver unit that receives stitchwork data on a stitchwork pattern selected and currently stitched by a sewing machine, a converter unit that converts the received stitchwork data into a unique code, a status data receiver unit that receives a unique code converted based on the stitchwork data currently stitched by the sewing machine, and a code comparator unit that compares a code converted by the converter unit with a code received by the status data receiver unit. The stitchwork data receiver unit receives the stitchwork data through a transmission protocol that surely transmits data to a transmission destination. The status data receiver unit receives the code through a transmission protocol that transmits data to a transmission destination within a short time. | 02-12-2015 |
20150040810 | STITCHWORK STATUS CHECKING SYSTEM, STITCHWORK STATUS CHECKING APPARATUS, STITCHWORK STATUS CHECKING METHOD AND STITCHWORK STATUS CHECKING PROGRAM - A sewing machine includes a temporal memory that stores stitchwork data currently stitched, and a first CRC data converter unit that converts the stitchwork data into unique codes. A stitchwork status checking apparatus includes a temporal memory that stores stitchwork data, a second CRC data converter unit that converts the stitchwork data stored in the local temporal memory into unique codes, and a CRC data converter unit that compares the codes converted by the first CRC data converter unit with the codes converted by the second CRC data converter unit. The stitchwork data stored in the temporal memory of the stitchwork status checking apparatus is the stitchwork data currently stitched by the sewing machine and transferred via a wireless network. | 02-12-2015 |
20150013583 | THREAD HOLDING MECHANISM OF SEWING MACHINE, NEEDLE THREADER THEREOF, AND SEWING MACHINE - A thread holding mechanism of a sewing machine which holds a thread supplied from a thread supply source includes a thread gripper unit that grips one end of a supplied thread, and a thread presser unit structured in a unified manner with the thread gripper unit and provided between the thread gripper unit and the thread supply source. Provided at the thread-supply-source side is a thread guide that guides another end of the thread, and when the thread gripper unit descends below the thread guide, the thread presser unit abuts the thread. | 01-15-2015 |
20150013582 | NEEDLE THREADER OF SEWING MACHINE AND SEWING MACHINE - A needle threader includes a needle bar supporter to which a needle bar holding a needle with a needle hole is attached, a threader shaft supported in a movable manner in a vertical direction and in a rotatable manner, a thread holding mechanism and a threader mechanism which is held by the threader shaft and which comprises a threader hook. The threader hook includes a capturing portion that captures the thread at a tip part of the capturing portion. The capturing portion includes a thread pathway and a thread capturing space. A width of a part where the thread pathway becomes the narrowest is formed so as to be narrower than a width of the thread capturing space. The thread enters or leaves the thread pathway in a tensioned condition, and the width of the part where the thread pathway becomes the narrowest is formed. | 01-15-2015 |
20140373766 | NEEDLE PLATE OF SEWING MACHINE - A needle plate of a sewing machine mounted on an upper surface of a bed of the sewing machine includes a support surface for supporting a fabric pressed by a presser foot, a needle opening through which a needle passes, and a feed dog slot through which a feed dog moves up and down and back and forth.
