摘要： A miniature handy electric sewing machine includes a casing including a grip portion, a sewing table projecting from one end of the casing, a sewing head pivotally mounted on a rear end of the sewing table and including a sewing needle fastened to its front end, and a cloth presser lever having at its front end a pressing portion which is pressed against an upper surface of the sewing table by a spring force. The cloth presser lever is pivotally mounted on the rear end of the sewing table together with the sewing table. The sewing machine further includes an oscillation mechanism for vertically oscillating the sewing head and a feed mechanism operatively connected to the oscillation mechanism for feeding an object to be sewed by predetermined pitches, the object being held between the sewing table and the pressing portion of the cloth presser lever. An operation lever is mounted at one side of the grip portion for pushing the cloth presser lever against the spring force, permitting the pressing portion of the cloth presser lever to depart above the sewing table. The operation lever may be pivotally mounted on a shaft further mounted on the casing.

摘要： A miniature electric sewing machine includes a shaft support bracket mounted on one side of a casing, a rotatable shaft supported on the shaft support bracket for rotation so as to extend in parallel with the side surface of the casing, a spindle support arm fixed to the rotatable shaft, and a bobbin winder spindle fixed to a distal end of the spindle support arm so as to extend in parallel with the rotatable shaft. The spindle support arm has a length of 35 mm or more. The spindle support arm fixed to the rotatable shaft assumes a position where it is normal to the side face of the casing or another position where the bobbin winder spindle fixed to the distal end of the arm is directed obliquely downwardly. A stopper is formed on the spindle support arm to be abutted against the side face of the casing when the arm is normal to the casing side face, preventing further upward rotating movement of the arm from the normal position. A large diameter bobbin is loosely fitted onto the bobbin winder spindle and subsequently, a rubber ring is attached to the spindle for preventing the bobbin from falling off.

摘要翻译： 微型电动缝纫机包括安装在壳体一侧的轴支撑支架，支撑在轴支撑支架上以便与壳体侧面平行延伸的可旋转轴，固定在壳体上的主轴支撑臂 可旋转的轴以及固定到主轴支撑臂的远端以与可旋转轴平行延伸的绕线筒绕线轴。 主轴支撑臂的长度为35mm以上。 固定在旋转轴上的主轴支撑臂呈现与壳体侧面垂直的位置或固定在臂的远端的绕线筒主轴向下倾斜的位置。 当臂垂直于壳体侧面时，在主轴支撑臂上形成止动件以抵靠壳体的侧面，防止臂从正常位置进一步向上旋转。 一个大直径梭芯松动地安装在绕线器主轴上，随后，一个橡胶环被安装到主轴上，以防止线轴脱落。
