摘要： A switch (50) is adapted to be On when a contact point (52) is at a position to be in contact with a cam surface (47) and Off when the contact point (52) is at a position corresponding to a non-cam surface (48). In the vicinity of the non-cam surface (48) of the cam surface (47), a rib (49) is provided which changes a direction of the contact point (52) when reciprocation of the cam member (43) is changed. Accordingly, even when the switch (50) comes into contact with the cam member (43) moving in a different direction, the direction of the contact point (52) is changed so as to be the same. Hence, the switch (50) is prevented from being affected by a hysteresis caused by difference in directions of the contact point (52).

摘要翻译： 当接触点（52）处于与凸轮表面（47）接触的位置时，开关（50）适合于接通，当接触点（52）位于与非凸轮 凸轮表面（48）。 在凸轮表面47的非凸轮表面48附近，提供了当凸轮件43的往复运动发生改变时改变接触点52的方向的肋49。 因此，即使当开关（50）与沿不同方向移动的凸轮构件43接触时，接触点52的方向变化为相同。 因此，防止开关（50）受到由接触点（52）的方向的差异引起的滞后的影响。

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.

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.
