    摘要: A printer of a wire-dot impact type is provided forwardly of the housing an inlet opening for introducing a printing paper to the inside and has an outlet opening provided at a rear side of the housing for discharging the printing paper to the outside. The printing paper is transported by cooperation of a tractor arranged near the outlet opening and a feed roller arranged near the inlet opening, to thereby run inside the housing in substantially a straight path of travel from the inlet opening to the outlet opening, during which the printing paper is printed by means of a platen and a printing head, both provided between the feed roller and the tractor. A pair of guide members are provided between the feed roller and the printing unit and between the printing unit and the tractor, respectively, to thereby feed the printing paper along the straight path of travel.

    摘要: A pattern stitch sewing machine is disclosed in which enlarged patterns are made possible by storing a plurality of divided part patterns in an electronic memory. Further data for stopping the sewing needle at its lower dead point at the end of each part pattern is provided so that the operator may shift the fabric about the needle in preparation for sewing a succeeding part pattern.

    摘要: The sewing machine is provided with two knobs on the front face of the machine housing and a number of switches indicating different stitch patterns to be produced. These knobs may be selectively pushed or rotated to set the sewing machine between a condition in which the needle and the feeding device are set to produce predetermined stitch coordinates of a selected pattern and a condition in which the needle and the feeding device are adjusted to produce adjustable stitch coordinates. The sewing machine further includes switches operated by the aforementioned knobs and an electric memory connected to a manually operated controller and functioning for controlling the swinging amplitude of the needle and the feeding pitch of the feeding device.

    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.

    摘要: A device for automatically adjusting the tension of a lower thread, which comprises a lower thread bobbin arranged on a bottom plate of a bobbin carrier turnably carrying the bobbin, a loop taker mounted on a magnetic shaft, and an energizing coil arranged around the magnetic shaft and providing together with said bottom plate and magnetic shaft a path of magnetic flux. The device is further provided with a detector detecting the consumed amount of the bobbin thread and a control circuit for energizing the coil when the lower thread is wound to the maximum capacity of the bobbin, interrupting the light of the detector. The detector operates the control circuit to decrease the amount of electric current applied to the energizing coil so as to set the lower thread tension back to its initial predetermined value.
