Abstract: A CD player, which comprises a conveying roller, a first sensing rod, a second sensing rod, a linkage member, a first switch and a second switch; wherein the linkage member is used for transmitting the rotation of the first sensing rod to the second sensing rod and provided with a first retaining part, a first clamping part, a second retaining part, a second clamping part; the two retaining parts are respectively arranged on both sides of a centerline of a CD conveying path; when the first sensing rod is prevented from rotating by the first retaining part, the second sensing rod is used for releasing the behavior; and when the second sensing rod is prevented from rotating by the second retaining part, the first sensing rod is used for releasing the behavior. The player can avoid the malfunction of a major-diameter CD detection switch and has a very simple structure.

Abstract: A compact disc (CD) player, which comprises playback substrates, a conveying roller, CD sensors, a CD stopper, a first trigger member, frame members, cam members and moving members, wherein the CD stopper has a major axis and abutting portions disposed at both ends of the axis; the first trigger member rotates when a minor-diameter CD stops at a mounting position on a turntable; the frame members receive the movement of the first trigger member; the cam members are coupled to the frame members; the moving members receive the rotation of the CD sensor and move along the outside diameter of a CD; the moving members are provided with clamping portions and abutted portions configured to be clamped with the abutting portions; and the cam members are provided with clamped portions configured to abut against the clamping portions.

Abstract: A wireless charger installed with a two-dimensional moving mechanism which is simply configured, inexpensive and can be easily miniaturized is provided wherein a table is freely moved in the X-axis direction and the Y-axis direction. In the two dimensional moving mechanism, each pair of X axis pinions are arranged to simultaneously mesh with teeth near both ends of each rack arranged on an X axis slider and Y axis slider respectively. Each pair of pinions are driven by each motor and rotated in synchronization.

Abstract: The present invention proposes a disc player without risk of damaging a disc and which has the ability to achieve the miniaturization and simplification of the construction. A disc is fed by transferring the loading motor power to a roller through a operation means and a clutch means. Further, a guidance rack plate is engaged with the operation means gear by the disc moving power, and a slider is engaged with the operation means gear by movement of the guidance rack plate which receives the power of the loading motor. Furthermore, the clutch means is removed from the power transfer path by the slider movement causing the roller to separate from the disc and move the clamper to the disc clamping position.

Abstract: The present invention proposes a double disc insertion preventing apparatus for a disc player with a simple construction while improving thinning.

Abstract: The present invention aims at providing a pickup unit that can freely select the mounting position of an adjusting screw for making tilt adjustment and facilitates the miniaturization and thinning. An energizing force in the tracking direction at the end of main guide is received by an adjusting plate, and the adjusting plate is apart from the unit substrate by fixing its one end to a unit substrate and bringing its other end into contact with a main guide, and providing a flexible part near the one end and a through-hole near the other end in an intermediate section.

Abstract: The objective of the present invention is to provide a viscous fluid sealing damper having a compact and simple structure in which a sealed vessel is made of a single material having a high stirring efficiency and attenuation rate. The present invention proposes a viscous fluid sealing damper interposed between a first member and a second member for attenuating vibrations propagated between the first and second members, wherein a stirrer protrudes within a sealed vessel filled with viscous fluid and made of a single material from one end toward the other end thereof; a thin-wall is provided between the one end and the barrel of the sealed vessel; a first fitting is provided at the one end outside the outer periphery of the stirrer; and a second fitting is provided on the outer periphery of the barrel of the sealed vessel at a position where it surround the tip of the stirrer and its vicinity; and the first fitting is fitted on the first member and the second fitting is fitted on the second member.
