摘要 |
An array of optical fiber sensors is installed in an automatic player piano for monitoring the hammers, and a data processing system produces music data codes through the analysis on the current hammer positions reported by the optical fiber sensors, wherein each optical fiber sensor has a sensor head separable into a head body and a holder so that an assembling worker fixes the optical fiber to the sensor head by pressing the optical fiber to the head body with the holder.
