Summary:PURPOSE:To surely connect an optical pickup device to a magnetic head device even when the verticality and the positional accuracy of a shaft hole and a shaft pin are not finished with high accuracy at a connecting part of the optical pickup device to the magnetic head device. CONSTITUTION:A connecting part 400 of an optical pickup device 5 to a magnetic head device 6 is formed in such a way that the tip part of a shaft pin 406 on one side is formed to be a taper shape and that it is faced with the opening edge of a shaft hole 404 on the other side so as to produce a gap in the axial direction in the raised position of a frame member 23 for magnetic- head raising and lowering use; the shaft pin 406 is coupled to and can be connected to the shaft hole 404 in the lowered position.
