摘要： In a wire-dot impact type printer a cylindrical platen and a printing paper are rotated or transported at the same rate, by connecting them to a single and common electric motor through a first and second transmission mechanisms, respectively. The first transmission mechanism directly connects the platen to the motor to cause the former to rotate together with rotation of the latter in any direction, whereas the second transmission mechanism includes a clutch composed of a first and a second members rotatable about a common center axis but separately from each other in which the first member is caused to rotate together with rotation of the motor in any direction while the second member is caused to rotate together with the first member being rotated in one direction but prevented from rotating when the first member is rotated in the other direction. In the latter case the platen is rotated for color changing operation, but the printing paper is prevented from running through the printer.

摘要： An electronic sewing machine with a dot matrix display for representing the image of a selected pattern to be stitched, having a first memory which stores stitch control data which may be sequentially read out in dependence upon a selected pattern per rotation of the sewing machine and transmitted to a driving part of a stitch forming mechanism; prior to initiation of the driving part, a calculator receives the read out stitch control data to make calculations for linearly interpolating between the adjacent stitches, thus to repeatedly renew the stitch control data into display data; a second memory stores the display condition data for controlling the cycle of pattern unit to be displayed; a counter counts up the cycles of the selected pattern in reference to the renewed stitch control data. Thus when the display calculations are finished through out the pattern cycles, the sewing operation is made possible, and the calculated display data are temporarily stored in a third memory to drive the dot matrix display of the sewing machine.

摘要： A single-thread chainstitch and a two-thread hemstitch which is made by a single needle are formed simultaneously, a part of the thread (T2) which forms the hemstitch being guided through a loop (1) to form the chainstitch, in order thereby to produce reinforced sewing stitches which come loose only with difficulty even when the thread (T1) of the chainstitch tears. The sewing stitch thereby acquires sufficient strength and stability and is suitable as a sewing stitch with a smaller number of sewing threads.

摘要： An improved method of hem-stitching employing a zigzag sewing machine having a vertically and laterally reciprocating needle adapted to penetrate into a sewn fabric to form lock stitches with upper and lower threads, and having a feeding device operated to feed the fabric in one direction and in the opposite direction, the hem-stitching method comprises: a step to produce at least two stitches at one point adjacent to the edge of the fabric with the feeding operation in one direction; a step to produce at least two spaced apart stitches with the feeding operation in one direction, said stitches being spaced from each other in a vertical direction and laterally spaced from the stitches produced at said one point, and a step to produce at least two fixing stitches with the feeding operation in one direction between the stitches produced at the one point and the stitches spaced from each other in the vertical direction and laterally spaced from the stitches at the one point, the fixing stitches being vertically spaced from each other and connected to the stitches produced at the one point with the feeding operation in one direction, and also connected to the said spaced apart stitches with the feeding operation in the opposite direction; the improved method avoids the troublesome operation of exchanging the presser foot and the need for an additional attachment in the sewing machine.

摘要： A pattern selecting device for a sewing machine of the type having a housing, a panel mounted on the housing for indicating a number of pattern indicia to be selected by the sewing machine operator, and an electronic memory storing a number of stitch control data for producing the stitches in accordance to the pattern indicia. The panel is provided with a first portion carrying a first group of pattern indicia and a second portion for indicating a second group of pattern indicia and a third group of pattern indicia. The pattern selecting device includes two screening plates mounted on the second portion. Both plates are movable relative to the second and third groups of indicia in the second section to selectively hide one of the second and third groups of indicia and visualize the other of the second and third groups of indicia or to hide both the second and third groups of indicia. The device is further provided with a switching arrangement operated to move the screening plates relative to the second and third groups of indicia. The switching arrangement produces a first electric signal when the screening plates hide one of the second and third groups of indicia and visualize the other of the second and third groups of indicia, and produces a second electric signal when the screening plates hide both of the second and third groups of indicia.
