In a disk device, a base body (10) has a drawing lever (80) for inserting a disk, a discharge lever (100) for discharging the disk, and a slider mechanism for pivoting the drawing lever (80) and the discharge lever (100). The slider mechanism has a first cam groove for sliding a first pin of the drawing lever (80) and a second cam groove for sliding a second pin of the discharge lever (100). The drawing lever (80) pivots when the first pin slides in the first cam groove as the slider mechanism operates, and the discharge lever (100) pivots when the second pin slides in the second cam groove as the slider mechanism operates.

该光盘装置，在基座本体(10)上设置插入光盘的引入杆(80)、排出光盘的排出杆(100)以及使引入杆(80)和排出杆(100)转动的滑动机构；在滑动机构上具有使引入杆(80)的第一销滑动的第一凸轮槽和使排出杆(100)的第二销滑动的第二凸轮槽；通过第一销随着滑动机构的动作在第一凸轮槽内滑动，引入杆(80)进行转动，通过第二销随着滑动机构的动作在第二凸轮槽内滑动，排出杆(100)进行转动。

It gets two conclusions. The first one is that the smaller the angle of the parallel joint pole is, the more quickly increasing push-force which acts on the oriented pin does. So it must try to pull out the inserting and drawing mechanism when the parallel joint pole is at the larger angle in order to reduce the extent of the inserting and drawing, i.e. trying to increase L_. The second one is that the forces which are exerted onhydraulic damper is more than the ones which are exerted on the oriented pin.

可知随着平行连杆所处的角度越小，导向销受到的推力增加得越快，所以要设法让插拔机构在平行连杆处于较大的角度时拔出，缩短插拔过程的行程，即应设法增大L_；在插拔机构的工作行程中，液压阻尼器所受到的冲击力大于导向销所受到的推力。
