<P>PROBLEM TO BE SOLVED: To prevent damage caused as a left LED 88 of an LED substrate 69 makes contact with a left light guide plate 35 of a normal start port 30. <P>SOLUTION: A left plate 32 of the normal start port 30 emits light when light is supplied. The left light guide plate 35 of the normal start port 30 supplies projection light from the left LED 88 to the left plate 32, and opposes the left LED 88 via a first gap. A left opposing plate 37 of the normal start port 30 opposes the LED substrate 69 via a second gap smaller than the first one. The left opposing plate 37 makes contact with the LED substrate 69 when the relative arrangement of the two is shifted so that the normal start port 30 approaches the LED substrate 69 as compared with target distance, thus preventing the left light guide plate 35 from making contact with the left LED 88. <P>COPYRIGHT: (C)2012,JPO&INPIT |
