Abstract:
A pickup device comprising:a movable frame that holds a pickup; a guide shaft that guides travelling of said movable frame in directions along which said movable frame approaches and separates from a disk table; and a tilt adjusting mechanism including; a flat rising end face that is disposed on a support frame and that is perpendicular to a plate face of said support frame, a spring member that is held by said support frame, that is contacted at a straight tip end portion to an end portion of said guide shaft to elastically urge the end portion of said guide shaft in an upward direction along which the end portion separates from the plate face of said support frame, a head screw including a head, said head having a downward-tapered pressing face which is contacted to the end portion of said guide shaft that is elastically urged in the upward direction by said spring member, wherein said downward-tapered pressing face cooperates with the tip end portion and said rising end face of said support frame to pressingly hold the end portion of said guide shaft, wherein said downward-tapered pressing face enables the end portion of said guide shaft to be pressed down while causing the end portion to slide over said rising end face, and a tapped hole which is formed in said support frame, and into which said head screw is screwed, thereby supporting said head screw in parallel with said rising end face, wherein said tip end portion of said spring member straight elongates from a side of said head screw screwed into said tapped hole toward said rising end face while passing below said end portion of said guide shaft and inclined to be lowered as elongating, and a tilt angle of said tip end portion with respect to said rising end face is set to an angle at which said end portion of said guide shaft cannot be pressingly fixed by only said tip end portion and said rising end face.
