Abstract
To provide a disc drive device which does not spend a lot of money on components and requires the less number of components than the conventional technology and has a function to correctly dispose an inserted disc by a slot-in method at a place where the disc can be driven according to the size of the disc. The disc drive device comprises an abutment pad which receives the inserted disc in a different posture depending on the size of the disc, a coupling member which rotationally transfers by a different distance at a different position according to the posture of the abutment pad when it rotationally transfers along with the bring-in operation of the disc, and a spring which applies a predetermined energizing force to the coupling member. Due to the coupled operation of these components, etc., the inserted disc can be correctly disposed at a predetermined place where the disc can be driven according to the size of the disc.
