摘要： A devised shank is provided to a presser foot of a sewing machine in addition to an ordinary shank, such that a special presser group for straight stitching along a fabric edge is attached to the devised shank only, in which the presser foot is attachable to a presser holder, and the ordinary shank is for such as zigzag stitching, and the devised shank is different in an attaching width from the ordinary shank. Signal generating parts are provided to the presser holder, which each issue a signal in response to when the presser foot is attached, and the signal is discriminated with a signal issued in response to a pattern group belonging to patterns selected by a pattern selecting means so that the sewing machine is driven only when the presser group and the pattern group is met.

摘要： The tension of the sewing machine's upper thread is varied automatically, in a variety of ways not requiring conscious participation on the part of the user of the machine. When one of a set of selectable stitch-patterns is selected by the user, an appropriate thread-tension value is automatically established, although the user retains the ability to adjust the automatically established tension value if he wishes. When the user swings the presser-foot lever of the machine up, to raise the cloth presser foot up from the cloth, e.g., for basting work, the thread tension is automatically lowered to a predetermined value suitable for basting, although still adjustable by the user if he thinks necessary. Where a stitch-pattern is implemented using an addressable ROM, tension command data for each stitch of the stitch-pattern may be stored in the ROM, for variation of thread tension from constituent stitch of the pattern to the next. Alternatively, the ROM stores no tension control data per se, and instead a calculating circuit calculates, from the mere stitch-control data presented by the ROM, distance-dependent values dependent upon the distances between successive needle-penetration locations of the stitch-pattern, and from those derives appropriate tension command signals.
摘要翻译：缝纫机的面线的张力自动变化，不需要意识地参与机器的使用者的各种方式。当用户选择一组选择性针迹图案中的一个时，自动建立适当的线张力值，尽管如果用户希望，用户保留调整自动建立的张力值的能力。当使用者向上摆动机器的压脚时，将布压脚从布上抬起，例如用于烘烤工作时，线张力自动降低到适合于烘烤的预定值，尽管仍然可以通过如果他认为必要的话。在使用可寻址ROM实现针迹图案的情况下，针迹图案的每个针迹的张力指令数据可以存储在ROM中，用于将线张力从图案的构成线圈变化到下一个。或者，ROM不存在张力控制数据本身，而是由计算电路根据由ROM提供的单纯缝合控制数据计算取决于针迹图案的连续针刺位置之间的距离的距离相关值，并从那些获得适当的张力指令信号。

摘要： A rows-and-columns array of indicator lamps, each lamp associated with a selectable stitch pattern, is provided on the machine housing, with one pushbutton switch per column of indicator lamps. In a first embodiment, when a particular column and row contain the single illuminated one of the lamps, depression of the pushbutton switch associated with a different column terminates illumination of the presently lighted lamp and instead effects illumination of the lamp of the same row but in the column associated with the newly depressed pushbutton switch, whereupon repeated pressing of the newly pressed switch causes the illuminated state to shift, lamp by lamp, along such column. Alternatively, when the illuminated-lamp indication is located in a particular row and column, depression of the pushbutton switch associated with a different column causes the illuminated-lamp indication to jump to that column, and in particular always to a predetermined lamp within that column, e.g., the first therein. In this way, when the number of selectable stitch patterns is large, a comparatively small number of pushbutton switches can be utilized to control pattern selection in a way involving a regular and predetermined rule of displacement of the illuminated-lamp indication from column to column.
摘要翻译：指示灯的行和列阵列，每个与选择性针迹图案相关联的灯被提供在机器壳体上，每列指示灯具有一个按钮开关。在第一实施例中，当特定的列和行包含单个照明的灯中的一个时，与不同列相关联的按钮开关的按下终止了当前点亮的灯的照明，而是实现同一行的灯的照明，与新按压的按钮开关相关联的列，由此重复按下新按压的开关，使得照明状态沿灯塔沿灯柱移动。或者，当照明灯指示位于特定行和列中时，与不同列相关联的按钮开关的按下导致照明指示灯跳转到该列，并且特别地总是到该列内的预定灯，例如，其中的第一个。以这种方式，当可选择缝合图案的数量大时，可以使用相对较少数量的按钮开关以以涉及从列到列的照明灯指示的规则和预定的位移规则的方式来控制图案选择。
