摘要：
An optical sensor (22) for an evaluating device on a sewing machine has a light transmitter (4) and a light receiver (21), which is separate from the light transmitter (4), and is arranged in a needle plate (17) in the path of the beam from the light transmitter (4). The transition (24) between the needle plate (17) and the support (15) is designed as an interface (25) with predescribed positions for transferring electronic signals and predescribed positions being fitted as contacts (26,27) and counter-contacts (28,29).
