摘要： A full rotary hook unit is provided below a needle plate of a sewing machine and is provided with an outer hook having a beak rotating integrally with a lower shaft in synchronization with a vertical movement of a sewing needle and a middle hook rotatably supported by the outer hook. A needle guide element that guides the sewing needle as well as adjusting the clearance between the sewing needle and the beak is formed independent of the outer hook and the middle hook. A position adjustment mechanism is provided that mounts the needle guide element on the outer hook or an element rotating integrally with the outer hook so as to allow adjustment of the positioning of the needle guide element in an axial direction of the lower shaft, thus allowing the clearance between the sewing needle and the beak to be readily adjusted.
摘要翻译：在缝纫机的针板的下方设置有全旋转钩单元，并且与缝纫针的垂直运动和由外部可旋转地支撑的中间钩同步地设置有具有与下轴一体旋转的喙的外钩钩。引导缝纫针以及调节缝纫针和喙之间的间隙的针引元件独立于外钩和中钩形成。提供了一种位置调节机构，其将针引导件安装在外钩或与外钩一体旋转的元件上，以便能够沿着下轴的轴向调整针引元件的定位，从而允许缝纫针和喙之间的间隙容易调整。

摘要： A wall (35) of an inner loop taker (15) includes a guiding surface (36), a first vertical surface (37) which extends continuously to an inward end (P5) of a guiding surface (36) in a radial direction of the inner loop taker (15) and is parallel to an axial line (L1) of a needle (11), and a second vertical surface (38) which is formed on the inward side of the first vertical surface (37) in the radial direction of the inner loop taker (15) but closer to the axial line (L1) of the needle (11) than the first vertical surface (37) and which is parallel to the axial line (L1) of the needle (11). An angle (θ 3) between a straight line which links the inward end (P5) and an outward end (P6) of the second vertical surface (38) in the radial direction of the inner loop taker (15) and the axial line (L1) is set smaller than an angle (θ 2) between a needle tip guiding surface (72) of the needle (11) and the axial line (L1), while a length (H3) of the first vertical surface (37) is set to be equal to or smaller than a distance (H4) along the axial line (L1) between a bottom end portion (P2) of an inner peripheral surface of an eye (43) of the needle (11) and a needle tip (P1) of the needle (11). With such a structure, breaking of the needle (11) due to collision between the inner loop taker (15) and the needle (11) and damage to a tip portion (40) of the needle (11) is reduced, so that damage to a needle thread (51) which is held between the needle (11) and the inner loop taker (15) is prevented.

摘要： A bobbin (40) which is housed in a bobbin case holder (30) is held, as it is elastically pressed by a peripheral wall (60) of a bobbin case (31). Passing through a gap (122) which is created between an outermost portion of a flange (97b) of the bobbin (40) which is disposed on an open end side of the bobbin case holder (30) and an inner peripheral surface of the peripheral wall of the bobbin case (31) and between the flange (97b) of the bobbin (40) which is disposed on the open end side of the bobbin case holder (30) and the inner surface of an end wall of the bobbin case (31), a bobbin thread (62) which is wound around the bobbin (40) is led outside through the bobbin thread leading hole (70) which is formed in the end wall (61) of the bobbin case (31). When the bobbin thread (62) is led out as sewing is started, since the bobbin (40) is held as it is elastically pressed by the peripheral wall (60) of the bobbin case (31) within the bobbin case holder (30), tension force of the bobbin thread (62) prevents the bobbin (40) from getting displaced within the bobbin case holder (30) in an axial line direction, and hence, an inconvenience that the tension force of the bobbin thread (62) varies is avoided, nonuniform fastening of the thread does not result, and the quality of sewing is improved.
摘要翻译：收纳在梭壳保持架（30）内的线轴（40）被筒管（31）的周壁（60）弹性地按压时被保持。穿过设置在梭壳（30）的开口端侧的线轴（40）的凸缘（97b）的最外部与周边的内周面之间产生的间隙（122）梭壳（31）的壁和位于梭壳（30）的开口端侧的线轴（40）的凸缘（97b）和梭壳的端壁的内表面如图31所示，卷绕在筒管（40）上的底线（62）通过形成于梭壳（31）的端壁（61）的底线导孔（70）被引导到外部。当缝线开始时，当底线（62）被引出时，由于线轴（40）被梭壳（30）内的梭壳（31）的周壁（60）弹性地按压，底线（62）的张力防止筒管（40）在轴线方向上在梭壳保持架（30）内移位，因此，底线（62）的张力变化的不便避免了螺纹的不均匀紧固，提高了缝纫质量。
