    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： 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.

    摘要： A front loading disk player of a type capable of playing disks of different diameters wherein the diameter and proper loading of the disk can be detected at all times with a simple sensor arrangement. The inventive disk player includes a housing, a playing mechanism provided in the housing and including an optical pickup and a turntable, the turntable including a tapered wheel received in the center hole of the disk, a disk conveying mechanism for conveying disks to the playing position, and a clamping mechanism for clamping disks conveyed to the playing position against the turntable. A detector detects the fact that the disk has been clamped against the turntable. This detector further includes a sensor having a detecting point within a range defined outside the outer circumference of the turntable and inside the outer circumference of the smallest diameter disk with the center of the rotary shaft of the turntable as the center of the smallest diameter disk, the range excluding a portion encompassed by a locus of cylinders having a diameter equal to that of the smallest disk circumscribing a reading spot on a locus of reading spots of the optical pickup and being tangent to the outer circumference of the tapered wheel. Further, a second sensor may be provided for detecting the presence of disks of diameter larger than the smallest diameter, the second sensor having a detecting point disposed separately from the detecting point of the first sensor by a distance equal to or larger than the outer diameter of the smallest diameter disk.
