    • There is disclosed a needle threader comprizing a support provided with a needle accommodating notch and a thread guide groove, and a pair of resilient rollers rotatably mounted on the support and contacting at the respective peripheral edges with each other. In the needle threader, an eye of a needle accommodated in the needle accommodating notch is located on a tangent line passing through the contact portion of the pair of resilient rollers. A thread introduced via the thread guide groove towards the proximity of the contact portion of the pair of resilient rollers is gripped by and transferred through rotation of the resilient rollers, resulting in the thread being passed through the eye of the needle.
    • 公开了一种包括具有针容纳凹口和导线槽的支撑的穿线器,以及一对可旋转地安装在支撑件上的弹性辊,并且在相应的周边边缘处彼此接触。 在穿线器中,容纳在针容纳凹口中的针眼位于穿过一对弹性辊的接触部分的切线上。 通过导线槽朝向一对弹性辊的接触部分的接近处引导的线被夹持并通过弹性辊的旋转传递,导致线穿过针的眼睛。
