IPC: G10H1/34
Filed: 2007-03-22
Abstract: <P>PROBLEM TO BE SOLVED: To provide a device capable of preventing a decrease in key displacement quantity detection precision due to optical interference and accurately computing a key depressing speed using the same.  <P>SOLUTION: The device which detects by a photoreflector a key displacement quantity for a keyboard musical instrument having a keyboard section comprising a plurality of keys includes a light shielding function for each key to stop optical interference. Namely, light shield plates 400 and 440 stop light sent and received to/from one key from interfering with light sent and received to/from another key, so the effect that a decrease in key displacement quantity detection precision due to optical interference can be prevented is obtained. Further, there is the advantage that it is easy to clean off dirt etc., during maintenance such as tuning of a piano because of a simple light shielding mechanism like this.  <P>COPYRIGHT: (C)2009,JPO&INPIT
