Abstract
There is provided an electronic musical instrument which enables the whole periphery of at least one pad member to shine by a simple construction, and at the same time maintain durability and low costs, and a shining method therefor. An electronic musical instrument of a drum type detects beats on a surface to be beaten of the pad member, and generates a musical tone signal in response to an output indicative of the detected beats. A light transmitter in a linear form is arranged along the periphery of the pad member and guides light which has been emitted from a light source arranged in the vicinity of one end of the light transmitter and entering the light transmitter via the one end, by utilizing principles of light propagation of an optical fiber, toward the other end of the light transmitter, and at the same time causes at least part of the light entering via the one end to emit out of the light transmitter via a light emitting surface formed by roughening part of an exposed surface of the light transmitter.
