<p><P>PROBLEM TO BE SOLVED: To fix a sensor block to a housing in such a way as to be rotatable freely by the use of a smaller number of components. <P>SOLUTION: The sensor block 15 is composed of an external rotating member 151 which is in the shape of a bowl having a diameter larger than a window hole 101a, projects on its pole side from the window hole 101a, and has a translucent pole portion; an internal rotating member 152 formed into the shape of a bowl which plugs up this opening; and a mounting board 153 which is housed in a hollow spherical substance composed of these, and has a brightness sensor mounted on its external member 151 side. A rotation fixing member 16 is formed into the shape having an annular part 161 which is smaller in diameter than the internal member 152, and in which its pole side fits, and is attached to a cover 11 to fix the sensor block 15 by the annular part 161 in such a way as to be rotatable freely. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
