    摘要： A front loading type disk player which can play both sides of a single disk without ejecting the disk from and reinserting it into the disk player after playing one side. In addition, the disk player can play one or both sides of multiple disks without ejecting or reinserting disks. The disk player includes a movable carrier on which at least two trays are movably mounted. The carrier can be moved in a first direction so as to project from or retract into a housing of the disk player, and the trays can be moved in the first direction with respect to the carrier and a second, vertical direction e.g. perpendicular to the first direction. The trays are moved by moving a chassis, which supports them, with respect to the carrier. The trays are independently movable in the first direction and the chassis 11 is movable in the vertical direction in a stepwise fashion so that the disks stored on the trays can be properly individually placed on the turntable and removed therefrom. In addition, there is a disk player for receiving multiple disks and selectively playing the received disks. The disks are received and stored in a vertical stack in a disk receptor, and a disk to be played is placed on a turntable.

    摘要翻译： 一种前挂式盘片播放器，可以播放单个磁盘的两面而不弹出磁盘，并在播放一面后将其重新插入到磁盘播放器中。 此外，磁盘播放器可以播放多个磁盘的一侧或两侧，而不会弹出或重新插入磁盘。 磁盘播放器包括可移动的载体，至少两个托盘可移动地安装在该移动托架上。 载体可以沿第一方向移动，从而从盘播放器的壳体突出或缩回到盘的播放器的壳体中，并且托盘可以相对于载体在第一方向上移动，并且可以在第二方向上移动托盘。 垂直于第一方向。 通过移动支撑托架的底盘来移动托盘。 托盘可以在第一方向上独立地移动，并且底盘11可以以逐步的方式在垂直方向上移动，使得存储在托盘上的盘可以适当地单独地放置在转台上并从中移除。 此外，还有一个磁盘播放器用于接收多个磁盘并有选择地播放所接收的磁盘。 将磁盘接收并存储在盘接收器中的垂直堆叠中，并且将要播放的盘放置在转盘上。

    摘要： An electromagnetic disturbance power (EDP) checker measures disturbance waves of an equipment under test (EUT), that is, a small electric appliance having a power cord. The EDP checker is capable of detecting and measuring disturbance waves even in sites more confined and having more external disturbance waves than in absorbing clamp method. The EDP checker includes a VHF current probe 2, a matching circuit 3 having input impedance matched at a reception frequency of a measuring equipment (receiver) 6 connected to the VHF current probe 2, and a circuit separating mains 4 for designating terminal impedance of the matching circuit 3 and eliminating influence of power source impedance. Power is supplied from the circuit separating mains 4 to drive the EUT 5 connected to the VHF current probe 2. The maximum value of disturbance power generated by the EUT 5 and supplied through the power cord 12 is measured by the measuring equipment 6 connected to the VHF current probe 2.
