Abstract: PURPOSE:To obtain interesting linear shading and to improve a decorative effect by turning on a light source and rotating a cam by external stimulus such as a sound, etc., making the end face of an optical fiber emit light and changing the state of the optical fiber by the press-contact of the cam and the elastic restoration of the optical fiber. CONSTITUTION:When a sensor switch 3 senses the specified sound, a motor 7 is rotated by a transistor circuit and the cam member 9 directly connected to the motor 7 is rotated, then the light source part 5 is turned on. While the optical fiber 10 is pressed to contact and act by the cam member 9, it changes its state and is elastically restored when the pressed state is released. The light from the light source part 5 arrives at the end face 10a from the end face 10b of the optical fiber and it is emitted. When the state of the optical fiber is repetitively changed and restored, light emission on the end face 10a gets from a point state to the linear shading or the contrary. Thus, the interest ing change of the light is enjoyed when it is viewed from the outside and the decorative effect is improved.
