Abstract: The disk carrier device comprises a carrier roller having a tapered surface with the diameter thereof becoming smaller gradually from the opposite ends towards the center, and a disk guide member integrally formed with a pair of tilted protrusions in the front and rear parts thereof which become gradually lower from the opposite ends towards the center. It is constructed such that the carrier roller is arranged between the pair of tilted protrusions to resiliently clamp the disk between the both tilted protrusions and the carrier roller to thereby carry the disk by the rotation of the carrier roller.

Abstract: The disk carrier device of the present invention comprises a carrier gear rotation-driven by a motor, control members driven by the motor via this carrier gear, for moving in one direction or in the other direction according to the direction of rotation of the motor, and a transmission gear which transmits the rotation of the motor to a feed roller. A rotation control section and a roller position control section are provided in the control member, respectively. At the time of ejecting the disk, with the movement of the control member, the feed roller is made to approach the disk guide by the roller position control section, and then the transmission gear is shifted to the transmission position by the rotation control section.

Abstract: It is an object of the present invention to provide a disk player by which position detection of a disk inserted and discrimination about whether the disk is a large one or a small one can be performed through a simple construction. A circuit board is provided either one side of a pair of detection levers which are rotated to be spread/closed while mutually interlocking with insertion of a disk or a disk guide board to which the detection levers are attached and a contact is provided on the other, and a rotary switch is composed of the circuit board and the contact so that through difference in output signal of the rotary switch, position detection of a disk and discrimination about whether the disk is a large one or a small one are performed.

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: It is an object of the present invention to simplify a structure for alternatively transmitting power to a pickup moving mechanism and a disk loading mechanism by a common motor. A worm gear is attached to the rotary shaft of a motor, a worm wheel meshing this worm gear is supported on a mobile plate 8 that is movable along the rotary shaft of the motor, and first and second gears which are positioned in right and left of the worm wheel to be alternatively capable to engage with the worm wheel are arranged. The pickup moving mechanism is operated by the mesh of the first gear and the worm wheel, and the disk loading mechanism is operated by the mesh of the second gear and the worm wheel.

Abstract: A disc transfer apparatus, which relies on a spring force for inserting a disc and on a motor for removing the disc, is provided to prevent the motor from acting as a load when the disc is inserted. A holding mechanism is provided in the disc transfer apparatus for holding a control gear included in a power transmission path (from a two-way motor for moving a pickup and for moving a push-back member), with respect to an upstream gear and a downstream gear without meshing therewith. The control gear is released from the holding mechanism by ejecting means.

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: A preset fishing line tension measuring device for permitting accurate fishing line tension adjustment with a drag mechanism is provided. A pair of fishing line guides are disposed in a spaced-apart relation to each other, and a tension sensor is disposed such as to provide an increased length of path of the fishing line between the two fishing line guided. Fishing line tension sensed by the tension sensor is displayed on a display part.

Abstract: The present invention relates to a disc ejecting apparatus for ejecting a disc by utilizing a pick-up drive motor. It is proposed to simplify the construction of the disc ejecting apparatus. A slip mechanism is provided in a route leading from the pick-up drive motor to a pick-up, and in the last stage of restoration of the pick-up to an initial position the disc ejecting mechanism is connected to the pick-up drive motor.

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.
