Abstract: A drive gear (30) is rotated by a motor (28). Drive force from a loading transmission gear (36), which constantly engages the drive gear (30), is constantly transmitted to a loading mechanism (20). In a pick-up moving mechanism (24), an idler gear (33), which constantly engages the drive gear (30), engages a pick-up transmission gear (82) to transmit drive force. The movement of a first slider (101) engages and disengages the idler gear (33) and the pick-up transmission gear (82). The first slider (101) is located at a first position when a disc (D) is not loaded, and is located at a second position when the disc (D) is loaded. A loading mechanism (20) ends a loading operation by moving the first slider (101) to a second position. The transmission and switching of drive force from a single motor to the loading mechanism (20) and the pick-up moving mechanism (24) is ensured.

Abstract: A disk insertion position setting device that can be compactly arranged. First and second sliding members 31 and 32, with disk contacting parts 39 and 41, are provided in a manner enabling sliding in directions that intersect a central line O of a disk insertion direction F. Sliding members 31 and 32 are urged by a spring 33 in directions in which disk contacting parts 39 and 41 approach central line O. A rotating member 34 is disposed in a rotatable manner between sliding members 31 and 32. By means of rotating member 34, the sliding of sliding members 31 and 32 in synchronization in mutually opposite directions is allowed and the sliding of just one of either sliding member 31 or 32 alone is restricted. A compact arrangement is realized by the use of sliding members 31 and 32 that slide in directions that intersect central line O.

A head 85 which is capable of moving parallel to the radius of the read/write compact disk to perform reading or writing of the read/write compact disk is provided. Head 85 has a stopper 145 which catches a catching portion 139 of setting/removing lever 136 at a position head 85 approaches closest to turntable 83. Cap portion 123 is provided with a setting/removing device 125.

Abstract: A compact disk changer includes a magazine having an inner body and an outer body that are rotatable independently of one another about a common axis of rotation. The inner and outer bodies are slideably interconnected by a helical member so that relative rotation between the bodies in a first direction increases the axial spacing between them and relative rotation in a second direction decreases the axial spacing. This construction reduces the size of the changer and does not require precision tolerances between moving parts. A plurality of compact discs are stacked within the magazine, and each disk is supported by a disk holder. When the disk at the top or end of the sack is to be played, relative rotation between the inner and outer bodies creates an axially extending space adjacent the selected disk and a playing mechanism is inserted into that space.

Abstract: A head device for a tape player has a head moving plate for bringing a head into contact with or pulling it away from a magnetic tape. The head is attached to a head holder. A forward azimuth adjusting screw and a reverse azimuth adjusting screw are adjustably screwed, in the vertical direction, through the head holder. A head driver moves the head holder up and down along the width of a magnetic tape. When the head driver is in motion, the azimuth adjusting screws are prevented from contacting a surface of the head device, thus reducing wear of the surface. Additionally, while the head driver is in motion, the head is set in a center position. When the head driver ceases motion, the azimuth adjusting screws contact a surface of the head device to adjust the azimuth and cause the head to be held at a height corresponding to the azimuth.

Abstract: A device for fast-forwarding and rewinding a tape includes a base plate supporting a fast-forward and rewind switch. Actuation of the switches rotates a reverse plate. A base plate with forward and reverse operating positions moves the reverse plate between first and second axes of rotation. A switching arm having an idler gear is selectively engageable between a forward and reverse drive system which winds a tape at high speeds. If the device is in a forward mode of operation, the switching arm rotates in the same direction as the reverse plate. If the device is in a reverse mode, the switching arm rotates in a direction opposite the reverse plate.

Abstract: A tape transport mechanism that senses the end of a tape while minimizing but not eliminating back tension at the tape-feeding end. Excessive back tension causes uneven transport in fast forward or rewind. Insufficient back tension causes slack that makes sensing the end of a tape impossible. Both result from keeping the torque identical on both takeup and feed reels. The mechanism automatically switches the torque as the tape reverses so that the takeup reel always has a higher torque than the feed reel, thereby insuring that the tape end is sensed and that tape transport is even regardless of speed.

Abstract: A switching plate includes a cam portion engaging a head moving plate for moving a head on an axis normal to a tape surface during a shifting operation so as to retract the head from the tape during shifts between forward and reverse to prevent surface damage to the tape. The switching plate carries a head driver having tapered ridges upon which a head holder rests. The head holder is movable on an axis parallel to the widthwise direction of tape. Shifting of the switching plate drives the head holder to rest upon elevated ridges for reverse mode operation or upon a second surface for forward mode operation.
