Electronic musical instrument

An electronic musical instrument of a keyboard type comprising:

• at least one key formed of a light transmissive member, said at least one key having a distal end and a proximal end, part of said key being roughened to provide a diffusing surface;
• at least one detecting device arranged for said at least one key, for detecting a key depressing operation applied to said at least one key;
• a musical tone signal-generating section that generates a musical tone signal in response to an output from said at least one detecting device;
• and
• a light source arranged in the vicinity of the proximal end of said key, for emitting light toward the root portion,
• wherein said key is configured such that light emitted from said light source and entering said light transmitter via the proximal end is guided by utilizing principles of light propagation of an optical fiber, toward the distal end, and at least part of the light entering via the proximal end is diffused at the diffusing surface so as to be visually recognized from outside of said light transmitter.

An electronic musical instrument of a drum type comprising:

• at least one pad member that has at least one surface to be beaten;
• at least one detecting device that detects beats on the at least one surface to be beaten of said at least one pad member;
• a musical tone signal-generating section that generates a musical tone signal in response to an output from said at least one detecting device;
• a case;
• a light transmitter arranged along a periphery of said pad member;
• a light source that emits light toward said light transmitter;
• a light transmitter holder that holds said light transmitter fixedly with respect to said case;
• and
• a tape material,
• wherein said light transmitter is press-fitted in said light transmitter holder via said tape material and held therein.

An electronic musical instrument of a drum type comprising:

• at least one pad member that has at least one surface to be beaten;
• at least one detecting device that detects beats on the at least one surface to be beaten of said at least one pad member;
• a musical tone signal-generating section that generates a musical tone signal in response to an output from said at least one detecting device;
• a case;
• a light transmitter arranged substantially along a whole periphery of said pad member, said light transmitter having a surface;
• a light source that is configured to be sufficiently smaller than said light transmitter, and emits light toward said light transmitter;
• and
• a holder that holds said pad member and said light transmitter fixedly with respect to said case;
• wherein at least part of said light emitted from said light source and transmitted through said light transmitter is visually recognized by being emitted out from said surface of said light transmitter.

• a light source that emits light toward said light transmitter;
• and
• a holder that holds said pad member and said light transmitter fixedly with respect to said case;
• wherein said light source is arranged at a location substantially below said pad member.

A shining method for an electronic musical instrument of a drum type, including at least one operating member at least part of which is formed by a light transmitter, the at least one operating member having one end, another end, a surface to be beaten, and a diffusing surface that is roughened, the electronic musical instrument detecting a beat on the surface to be beaten, and generating a musical tone signal in response to an output indicative of the detection,

• the method comprising the steps of:
• causing light from a light source to enter the at least one operating member via the one end;
• and
• guiding the light entering the operating member via the one end toward the other end by utilizing principles of light propagation of an optical fiber, and causing at least part of the light entering the operating member via the one end to be diffused at the diffusing surface so as to be visually recognized from outside,
• wherein the light source is arranged in the vicinity of the one end of the operating member.
