The luminous flux which is made incident on the light guide member 3 from the light source 2 while totally reflected in the light guide member 3 reaches every part of the light guide member 3. The direct illumination luminous flux from the light source 2 propagates through the light guide member 3, but is made incident at an angle below the critical angle, so the luminous flux exits from the light guide member 3 to illuminate an illumination position 5 directly.  Further, the luminous flux emitted by the light source 2 is made incident from a side part of the light guide member 3, propagated in the light guide member 3, and guided to the opposite side of the light guide member 3, so that a reflecting member 4 formed on the light guide member 3 reflects the light on the illumination position 5. At this time, the luminous flux illuminates the illumination position 5 from the direction wherein it crosses the luminous flux illuminating the illumination position 5 directly.

Abstract: PURPOSE:To reduce the emission or reflection of a noise caused by a frame to a great extent by a method wherein one or more through holes having an approximately the same total area as the plan project area of a type drum are provided on the frame below the type drum. CONSTITUTION:A frame 1 is an integrally molded plastic body with a large through hole 1-a opened on the center bottom thereof. The through hole 1-a is disposed right below a type drum 3 and has an approximately the same total area as the plan project area of the type drum 3. In this manner, with respect to the frame 1 excited by the reaction of the shop/rotation torque of the type drum 3, a sound wave emission area is remarkably reduced. Additionally, the sound wave emitted downward from the type drum 3 excited by the stop/rotation thereof or a hammer 9 striking a type diffuses downward without reflecting through a single large hole or a large number of small holes (which are through holes) provided on the frame 1. Therefore, the emission or reflection of a noise can be reduced to a great extent.
