PROBLEM TO BE SOLVED: To simplify a pickup inclination adjusting mechanism. SOLUTION: A guide shaft 4 for guiding a pickup 2 is fitted so as to be freely moved up and down in a support shaft 10 erected from a chassis 1. An adjusting mechanism 5 for changing the inclined angle of the guide shaft 4 in a plane orthogonal to the upper surface of the chassis 1, including the moving direction of the pickup 2, is provided with a compression spring 8 for pressing the guide shaft 4 upward, and an adjusting screw 6 engaged with the chassis 1 to bring a head part 60 into contact with the upper end surface of the guide shaft 4.
