  • Patent number: 12286737
    Abstract: A needle plate has a needle hole and a guide hole communicating with the needle hole. The guide hole is located near a front side of a sewing machine and positionally deviated from an up-down movement trajectory of a sewing needle in a rotating direction of a rotary hook. The needle plate has a groove formed in front of the needle hole and extending from the guide hole in a direction opposite to the rotating direction of the rotary hook. While the groove is open upward and at its portion leading to the guide hole, the other portions of the groove are defined by a bottom surface and side walls. In a sewing operation, depending on a direction in which a member holding a sewing workpiece moves, the lower thread passes through the guide hole to be guided to the front of the needle hole via the groove.

  • Patent number: 12281422
    Abstract: A presser foot device includes a pressing member and a guide member provided at the lower end of the pressing member. The guide member has an opening section provided to allow an upper thread to pass therethrough in a rotating direction of a rotary hook, and a restricting section provided to restrict movement of the upper thread in a direction opposite the rotating direction of the rotary hook. Upon determination that a direction in which a next stitch is to be formed belongs to a predetermined hitch-stitch forming area, detouring movement of a frame, holding the sewing workpiece, is carried out. This detouring movement includes moving the frame in such a direction in which the upper thread moves out of the opening section and then further moving the frame to a target position corresponding to the next stitch such that the upper thread abuts against the restricting section.

  • Patent number: 12281423
    Abstract: A rotary hook includes a bobbin case housing a lower thread bobbin, an inner rotary hook and an outer rotary hook. A needle drop hole is provided in an upper front surface of the inner rotary hook, and a recess is formed therein at a position deviated from the needle drop hole in a rotating direction of the outer rotary hook. The recess opens forward and upward and has a rear wall. The bobbin case provides with a thread take-up member for directing a lower thread, paid out from the lower thread bobbin, toward the recess. The lower thread paid out from the lower thread bobbin is passed through the recess via the thread take-up member and then directed to a needle hole of a needle plate provided above. With this arrangement, it is possible to structurally avoid occurrence of a hitch stitch caused by the lower thread.

  • Publication number: 20250091344
    Abstract: A liquid discharge apparatus includes a liquid discharge head and circuitry. The liquid discharge head discharges liquid droplets. The circuitry causes the liquid discharge head to selectively discharge two or more types of liquid droplets having a first droplet having a first discharge volume and a second droplet having a second discharge volume larger than the first discharge volume to form an image of dots of the first droplet and the second droplet on a medium with gradations according to a gradation value of the image on a portion of the medium. Further, the circuitry monotonically decreases a number of white pixels without discharging the liquid droplets on the medium with an increase in the gradation value.
