Summary:PURPOSE:To simplify the constitution of an optical disk record reproducer and at the same time to facilitate the control of a switch, by using a switch driving member which is attached to a pickup attachment member with correspondence to the switch and contains a driving part and a control part formed in a body. CONSTITUTION:A control screw 133 is put through a slit 132 and fitted to a projected part 129, and the angle of a sloping part 130 of a driving part 131 is controlled by the fastening degree of the screw 133. In other words, the part 131 of a control member 129 attached to a pickup attachment member 77 controls the screw 133 so that the part 131 drives a switch 26 when a pickup 25 is set at a base point (inner circumference part of a loaded disk) to the switch 26 for detection of pickup position. In such a way, the part 131 and a control member 126 are formed in a body. This facilitate an easy fine adjustment and also decreases the number of component parts. Furthermore, the workability is improved.
