摘要：PURPOSE: A timing roller or timing disk, and fabricating method thereof is provided to be used regardless of a wet atmosphere and 100°C temperature by setting an accurate location of a machine tool, a servo motor and an encoder. CONSTITUTION: A timing disk is composed as a film material(1a), a photo cream layer(1b), and a deposited thin film(1c). After being exposed and developed, a code masking(1d) is indicated as a black. The film material(1a) used as a carrier material is directly combined with a photo layer or a gelatin layer(1b). A transmitter(4) and a receiver(5) arranged on a common unit(6) are located at an external edge of a timing disk(1). The transmitter(4) and the receiver(5) are connected to a control circuit. A reflective layer is arranged on the film material(1a). The receiver(5) transmits a pulse to the control circuit.
