摘要： A disc unit includes: a slide stopper adapted to switch a state of the unit between an initial state, a guide-restricted state and a movement-unrestricted state by sliding in right or left direction; and a first plate spring and a second plate spring for biasing the slide stopper in the guide-restricted state or the movement-unrestricted state in a direction to return to an initial position. With this arrangement, the slide stopper can be constantly returned to the initial position unless in the guide-restricted state and the movement-restricted state. Thus, with a simplified arrangement, the disc unit can be switched between the initial state, the guide-restricted state and the movement-unrestricted state.
摘要翻译：盘单元包括：滑动止动件，其适于在左右方向上滑动来在初始状态，引导限制状态和移动无限制状态之间切换单元的状态; 以及第一板弹簧和第二板簧，用于在导向限制状态或运动无限制状态下将滑动止动件沿着返回到初始位置的方向偏压。通过这种布置，除非在引导限制状态和运动限制状态下，滑动止动器可以不断地返回到初始位置。因此，通过简化的布置，可以在初始状态，引导限制状态和移动无限制状态之间切换盘单元。

摘要： A disc unit includes a push arm for providing a predetermined clearance between a periphery of a large-diameter disc and a guide lever used for guiding insertion and ejection of the large-diameter disc. The clearance is formed by moving the guide lever toward a left wall when the large-diameter disc is clamped on a turntable. With this arrangement, when the large-diameter disc is mounted on the turntable, the rotation of the large-diameter disc is not hindered.
