|20150090169||BUTTONHOLE PRESSER DEVICE AND METHOD OF STITCHING BUTTONHOLE BY USING THE SAME - A buttonhole presser device includes a fabric presser unit; a fabric feed frame unit including a start position detecting member and an immovable receiving portion, the fabric feed frame unit being slidable relative to the fabric presser unit between a start position and an end position of the buttonhole; a button-diameter measuring unit including an end position detecting member and a movable receiving portion, the button-diameter measuring unit being configured to grip a button by being slid relative to the fabric feed frame unit; and a fixing unit that fixes the button-diameter measuring unit to the fabric feed frame unit when the button-diameter measuring unit is gripping the button between the immovable receiving portion and the movable receiving portion and that allows the button to be removed after the button-diameter measuring unit has been fixed to the fabric feed frame unit.||04-02-2015|
|20150068412||ELECTRIC PRESS, BEND-POINT DETECTION METHOD, AND PROGRAM - A detection unit for detecting a press position and a load at the press position; an input/storage unit for inputting and storing a value serving as a reference for determining a bend point in a relation between the press position and the load at the press position; a slope calculation unit for calculating a slope of the load based on the press position and the load at the press position, which have been detected; and a bend-point determination unit for determining a point, at which the calculated slope of the load exceeds the value serving as the reference for determining the bend point, as the bend point are provided.||03-12-2015|
|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. The support surface has small projections and recesses.||12-25-2014|
|20140346264||BOBBIN - A bobbin includes a bobbin main body including flanges at both ends of a bobbin winder spindle for winding the bobbin thread and an outer flange attached to one of the flanges (a second flange) of the bobbin main body. A gap in which a thread end of the bobbin thread is housed is provided between the outer flange and the flange of the bobbin main body.||11-27-2014|
|20140216316||EMBROIDERY CLOTH PRESSER - An object of the present invention is to provide an embroidery cloth presser which prevents a needle thread from being sandwiched between the embroidery cloth presser and a cloth to allow an embroidery frame to move smoothly and which also prevents inappropriate draw-in of the needle thread, that is, prevents a cross-over thread of the needle thread resulting from long-distance movement of the embroidery frame from remaining on an embroidery surface. An embroidery cloth presser is installed on a presser bar of a sewing machine to press a cloth to be embroidered and which includes a projection provided on a bottom surface of the cloth presser which contacts the cloth around a needle and forming, between the cloth presser and the cloth, a gap through which a needle thread passes.||08-07-2014|
|20140209002||SEWING MACHINE - The sewing machine has: a base plate that has a guide slit for guiding a bobbin thread that is set on the bottom face side of the throat plate||07-31-2014|
|20100229739||Imprinter - An imprinter includes a printing base for mounting a card and a print paper to be imprinted on a predetermined area thereof, a carriage that is movable above the printing base, a roller includes a hard material and is provided as is housed within the carriage for transcribing the information represented as embossed on a card, a roller shaft for fixedly supporting the roller, bearings for rotatably supporting the roller shaft at a position of a predetermined height from the card mounting surface of the printing base, and an elastic mechanism provided between the bearings and the roller shaft, the elastic mechanism being radially deformed during an imprinting operation to cause the roller to radially move relative to the bearings so that the embossed information of the card may be transcribed onto the print paper.||09-16-2010|
