Abstract: A disk device for playing back information recorded on an optical disk, includes a device body; a disk tray, moving in the device body between a charging position, into which the optical disk is charged, and a discharging position from which the optical disk is discharged; a chassis, provided in the device body; a turntable, moving between an ascending position and a descending position when the chassis is displaced, and the turntable on which the optical disk is set; and a disk clamper, pivotally arranged on an upper plate of the device body, and clamping the optical disk against the turntable when the turntable is moved to the ascending position. The disk clamper is arranged on the upper plate with a clearance therebetween so that the disk clamper is moved in all radial directions, and an amount of the clearance in a first direction, in which the disk tray moves from the discharging position to the charging position, is smaller than amounts of the clearance in the other directions.

Abstract translation: 一种用于播放记录在光盘上的信息的盘装置，包括：装置本体; 磁盘托架，其在装置本体中在光盘被充电的充电位置与放电位置之间移动; 设置在设备主体中的底盘; 转盘，当底盘移动时在上升位置和下降位置之间移动;以及转盘，其上设置有光盘; 以及圆盘夹持器，其枢转地布置在装置主体的上板上，并且当转盘移动到上升位置时将光盘夹紧在转台上。 盘夹持器布置在上板上，其间具有间隙，使得盘夹持器沿所有径向方向移动，并且盘托盘从排出位置移动到充电位置的第一方向上的间隙量 小于其他方向上的间隙的量。
