    • The apparatus for automatically changing records comprises a rotary store (3) rotating about a tube (2) which is inclined at about 45` with respect to the horizontal plane. The tube (2) carries a housing (4) containing a control mechanism to pull out a record (5) from the store (3) by means of a lever (18) and to bring it to its reading position (51). This control mechanism also provides for the setting into position and the withdrawal of a pickup arm (20). Owing to this inclined arrangement of the store (3), the overall dimensions in depth and height are less than in known apparatus.

    • A disk changer for CD and DVD disks including a rotatable platter with several slots each adapted for receiving a disk generally needs two optical sensors. The first sensor is adapted for detecting the number of a related slot of the platter and for providing a stop signal for the rotation of the platter. The second sensor is adapted for detecting the presence or absence of a disk in a given slot. Said sensors and their associated evaluation circuits are expensive components. Therefore it is an object to simplify the means for realizing said sensors. Said second sensor has the form of a link (8) hingedly mounted between its two ends (10, 11) a first end (10) of the link (8) contacting the surface of the disk (4) and a second end (11) of the link (8) cooperating with said first optical sensor (6). By this solution said second sensor and its associated evaluation circuit can be omitted substantially reducing the total costs of the changer.
    • 用于CD和DVD盘的盘片更换器包括具有适于接收盘的多个槽的可旋转盘,通常需要两个光学传感器。 第一传感器适于检测盘片的相关槽的数量,并提供用于盘片旋转的停止信号。 第二传感器适于检测给定槽中磁盘的存在或不存在。 所述传感器及其相关的评估电路是昂贵的部件。 因此,目的是简化实现所述传感器的方法。 所述第二传感器具有铰链安装在其两端(10,11)之间的连杆(8)的形式,所述连杆(8)的与盘(4)的表面接触的第一端(10)和第二端(11) )与所述第一光学传感器(6)协作。 通过该解决方案,可以省略第二传感器及其相关的评估电路,从而大大降低了更换器的总成本。

    • The invention relates to a motion control system for driving a motor-driven device precisely to a predetermined position in a short time. More particularly, this invention relates to a CD-carousel loader having a precise and short access to the next information medium. The object of the invention is to provide a motion control system for a platter of a CD carousel which requires little outlay and satisfies the requirements in respect of high positioning accuracy, short motion duration and self-locking. According to the invention, this object is achieved by means of a drive system comprising a motor driving circuit and a braking circuit having a common input terminal responsive to a pulse signal during a deceleration period in front of a predetermined position of the motor-driven device. The field of application of the invention is associated with apparatuses for the recording or for the reproduction of information with a device providing the scanning or recording system with the information medium by a platter of a CD carousel.
    • 本发明涉及一种用于在短时间内将电机驱动装置精确地驱动到预定位置的运动控制系统。 更具体地说,本发明涉及一种具有对下一个信息介质的精确和短时间访问的CD转盘装载机。 本发明的目的是提供一种用于CD转盘的盘片的运动控制系统,其需要很少的花费并且满足关于高定位精度,短运动持续时间和自锁的要求。 根据本发明,该目的是通过一种驱动系统实现的,该驱动系统包括马达驱动电路和制动电路,该制动电路具有在马达驱动装置的预定位置前面的减速期间响应于脉冲信号的公共输入端 。 本发明的应用领域与用于通过CD转盘的盘片向扫描或记录系统提供信息介质的设备记录或再现信息相关联。
