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.
