    • A controller of a sewing machine configured to execute a pre-positioning operation including controlling a needle bar driving mechanism, based on a thickness of a workpiece cloth detected by a thickness detection mechanism and a vertical position of a needle bar detected by a needle bar position detection mechanism, to stop a needle bar at a preset position immediately before a tip of a sewing needle pierces the workpiece cloth, controlling a pressure adjustment mechanism to adjust a pressure of a presser foot at a predetermined pressure that allows movement of the workpiece cloth, and controlling a feed dog switching mechanism to switch a feed dog to an inoperative state.
    • 一种缝纫机的控制器,被配置为执行预定位操作,包括基于由厚度检测机构检测到的工件布的厚度和由针杆位置检测的针杆的垂直位置来控制针杆驱动机构 检测机构,在缝纫针的尖端刺穿工件布之前,将针杆停止在预定位置,控制压力调节机构,将压脚的压力调节到能够使工件布移动的规定压力, 以及控制馈送狗切换机构将馈送狗切换到不工作状态。

    • A sewing machine includes a frame support portion, a moving device, a movable member and a detecting device. The frame support portion is configured to be detachably mounted with a mounting portion of an embroidery frame. The mounting portion has a specific shape that corresponds to a type of the embroidery frame. The moving device is configured to move the frame support portion. The movable member is configured to move in a first direction by a movement amount corresponding to the type of the embroidery frame, in conjunction with an operation in which the mounting portion of the embroidery frame is mounted on the frame support portion. The detecting device configured to detect the movement amount of the movable member, and to detect the type of the embroidery frame mounted on the frame support portion based on the detected movement amount.
    • 缝纫机包括框架支撑部分,移动装置,可移动部件和检测装置。 框架支撑部被构造成可拆卸地安装有刺绣框架的安装部分。 安装部具有对应于刺绣框架的类型的特定形状。 移动装置构造成移动框架支撑部分。 结合将绣花框架的安装部分安装在框架支撑部分上的操作,可移动部件被构造成沿第一方向移动与刺绣框架类型相对应的移动量。 检测装置,被配置为检测可移动部件的移动量,并且基于检测到的移动量来检测安装在框架支撑部分上的刺绣框架的类型。
