Abstract: A drive gear (30) is rotated by a motor (28). Drive force from a loading transmission gear (36), which constantly engages the drive gear (30), is constantly transmitted to a loading mechanism (20). In a pick-up moving mechanism (24), an idler gear (33), which constantly engages the drive gear (30), engages a pick-up transmission gear (82) to transmit drive force. The movement of a first slider (101) engages and disengages the idler gear (33) and the pick-up transmission gear (82). The first slider (101) is located at a first position when a disc (D) is not loaded, and is located at a second position when the disc (D) is loaded. A loading mechanism (20) ends a loading operation by moving the first slider (101) to a second position. The transmission and switching of drive force from a single motor to the loading mechanism (20) and the pick-up moving mechanism (24) is ensured.

Abstract: A disk insertion position setting device that can be compactly arranged. First and second sliding members 31 and 32, with disk contacting parts 39 and 41, are provided in a manner enabling sliding in directions that intersect a central line O of a disk insertion direction F. Sliding members 31 and 32 are urged by a spring 33 in directions in which disk contacting parts 39 and 41 approach central line O. A rotating member 34 is disposed in a rotatable manner between sliding members 31 and 32. By means of rotating member 34, the sliding of sliding members 31 and 32 in synchronization in mutually opposite directions is allowed and the sliding of just one of either sliding member 31 or 32 alone is restricted. A compact arrangement is realized by the use of sliding members 31 and 32 that slide in directions that intersect central line O.
