Abstract:

An extruded recording sensor mounting rail for keyboard operated musical instruments, particularly electronic player pianos, which can be used to install recording sensors in a new or existing piano and provide for accurate alignment of the sensors with the individual keys in the instrument. A first flange extending along the rear of the mounting rail is configured for receiving one edge of a circuit board in a sensor assembly, while a second flange and shelf extending along the front of the mounting rail are configured for supporting the other edge of the circuit board and flexible recording sensors. Each flange also includes longitudinal slots for receiving fasteners for joining multiple mounting rails in an end to end configuration so that mounting rail assemblies of varying lengths can be fashioned to accommodate different keyboard sizes and key spacing configurations.
