Japanese Patent JP3769920
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To ensure uniform brightness of a display plate by contriving the attaching structure of an operation knob to a light guide plate, in shch a manner that it can be prevented that a penetrating hole of the light guide plate, to which the operation knob used for display switching, zero return, etc., is attached, casts a shadow and exerts an influence upon the display plate.
SOLUTION: When a rod 40a of a zero return nob 40 is turned in the direction shown by an arrow (b) along a notched part 29 of a light guide plate 20A, the base part 42 of the knob receives the repulsive force of a coil 70 and moves in the direction shown by an arrow (c) along the notched part 29. Thereby a lower end cut division protruding part 45 is engaged with a bottom wall annular part of a cylindrical body 20a from the outside, and the base part 42 of the knob is set in an aperture side penetrating hole part 24a, i.e., a normal position.
