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 invention seeks to provide a disc centering device of simple arrangement in a disc player for laying large and small size discs. One of paired, i.e., left and right, leading members and a trigger member also serve as a pair of small size disc stoppers, and the other leading member is provided with the sole function of correcting the deviation of the small size discs. Thus, the problem of the difficulty of positioning by providing the paired leading members with stopper function, is solved with a simple arrangement.

Abstract: The invention is a proposal of a pick-up drive apparatus for a disc player, which permits reducing the rotation resistance offered by a feed screw for driving a pick-up. A guide shaft and a feed screw are disposed side by side. an engagement part of a coupling member is held in radial and elastically forced contact with the feed screw. With rotation of the feed screw, the coupling member is thus advanced and retreated in the axial directions of the feed screw. A pick-up seat carrying a pick-up is caused to follow the coupling member for advancement and retreat along the guide shaft. The coupling member is mounted on the guide shaft for rocking movement and axial advancement and retreat. The coupling member has a pair of clamping pieces clamping the feed screw from the opposite sides in the direction of rocking movement. The engagement part is formed on one of the clamping members.

Abstract: The present invention seeks to provide a disc transfer apparatus, which permits increasing the disc kick-off extent while holding a constant distance between a transfer roller and a turntable. A disc transfer apparatus is disclosed, which can choose either one of a play-back base fixing mode, in which a transfer roller is held at a disc transfer position while restricting motion of the play-back base relative to a housing, thereby permitting loading/unloading of disc, and a play-back base release mode, in which the transfer roller is held at a non-disc transfer position while holding the play-back base in a floating state relative to the housing.

Abstract: The present invention relates to restrict a disk playing base plate against movement in back-and-forth directions, lateral directions and vertical directions relative to a housing by making use of the movement of a roller holder supporting a disk carrier roller. A pair of (i.e., left and right) side plates 11 of the roller holder has roller holder contact parts for restricting movement in the back-and-forth, lateral and vertical directions, and the top and bottom plates of the housing have housing contact parts corresponding to the roller holder contact parts. When a disk carrier roller is in a disk carrying position, the front part of the disk playing base plate is restricted against movement in the back-and-forth, lateral and vertical directions relative to the housing.

Abstract: It is sought to simplify a disc centering device. Stopper portions for centering a small-size disc are provided on disc sensors, and guide portions are provided, which, when the disc sensors are moved with insertion of a large-size disc, engage with the disc sensors to move the stopper portions to the outside of a disc transport path.

Abstract: A resin composition has a phase separation structure having at least two phases and inorganic particles having a mean primary particle size of 0.1 &mgr;m or less. The phase separation structure includes a matrix phase and a disperse phase. The inorganic particles are mainly present in any one of the matrix phase, the disperse phase, and the interface between the matrix phase and the disperse phase. The resin composition has a high thermal expansion coefficient and elastic modulus, and thus provides an adhesive for semiconductor devices which has excellent reflow resistance and adhesion.

Abstract: When a roller holder attached to a floating chassis of the disk player rotates to raise a carrier roller from a disk non-carrying position to a disk carrying position, a convex portion of the roller holder is engaged with concave portions of the main chassis from above so as to fix the floating chassis to the main chassis in the back and forth directions as well as the right and left directions. The roller holder further rotates about a fulcrum to raise the floating chassis. As a result, the floating chassis is made to abut against another part of the main chassis from below to fix the floating chassis to the main chassis in the vertical direction.

Abstract: A simplified device is provided for fixing a floating chassis to a main chassis. The floating chassis fixing device has a control member movably mounted on one side of the floating chassis, a push-in member for transferring a disc to a playing position and a disc guide for guiding the disc to the playing position, which are coupled to the control member such that they are interlocked. When no disc is loaded, the control member, the push-in member and the disc guide are engaged with the main chassis to fix the floating chassis to the main chassis.

Abstract: To simplify the construction of a manual operating device for an auto-reverse cassette tape recorder, in which the feed direction of the tape is reversed by depressing an FF operating member and a REW operating member at a time. A FF/REW locking mechanism is rocked to a greater extent when a REW operating member is depressed alone than when an FF operating member is depressed alone. An auto-reverse mechanism is operated with the greater extent rocking movement of the FF/REW locking mechanism.

Abstract: In an operation switching apparatus for a tape recorder installed on a car etc., the present invention intends to improve a construction of a control cam plate for controlling various operation modes, to simplify mechanisms installed in the apparatus, to stabilize a control operation and to easily design a reduced size of the apparatus. A reversible rotary drive motor (16) drives a control cam plate (80) forward and backward. On the control cam plate (80) are provided a head moving cam (90) and a mode selection cam (92). A tape direction switching mechanism (100) and a FF/REW switching mechanism (120) are controlled by a common mode selection cam (90). By the control cam plate (80), various operation modes are selectively carried out. The control cam plate (80) is operatively connected to a cassette loading cam plate (60). The control cam plate (80) and the cassette loading cam plate (60) are driven by a single drive motor (16). After a cassette loading, both cam plates are disconnected.

Abstract: A tape cassette loading apparatus wherein various components can operate smoothly at suitable timings with a simple construction. A pivotal lever is pivoted at an initial stage when a tape cassette is inserted into a cassette holder, and a controlling member is moved a little forwardly by the pivotal lever. The movement of the controlling member is detected by a position detector, and a loading motor is controlled in response to a detection signal from the position detector. The controlling member is driven to move forwardly and backwardly by power of the loading motor, and a changing-over operation between loading and unloading of a tape cassette and a mode position changing-over operation of a head mounting plate are performed by the forward and backward movement of the controlling member.
