摘要： A mechanism for use in a cassette tape recorder automatically changes the mode of the recorder when the end of the tape is reached by sensing the cessation of rotation of the pinch roller. A mode change lever having an elongated hole with converging sides that receives a cylindrical portion of the pinch roller is biased by a spring so that the cylindrical portion engages the converging sides and the mode-change lever tends to rotate in a first direction. Once the pinch roller ceases to rotate, the mode-change lever is moved in a direction opposite the first direction and so that it cooperates with a mode-change drive assembly rotated by the capstan. The mode-change lever is then displaced and releases a mode key, so that the mode of the recorder is changed and is typically shut off.

摘要： A cassette tape recording and/or reproducing apparatus has a rectangular chassis on which a cassette holder is pivotally mounted for angular movement relative to the chassis about an axis extending along one long side of the chassis between an inclined cassette receiving position and an operative position in which a cassette in the holder is loaded flat against the chassis, a pivot on the cassette holder defines a pivot axis which is adjacent, and at right angles to the axis of movement of the holder, and a head base is mounted on the pivot for movement relative to the cassette holder between a rest position, in which a magnetic head mounted on the base extends a relatively small distance into a cassette inserted in the holder, and an active position, in which the head is further projected into a cassette in the operatively positioned holder.

摘要： A cassette tape player utilizes a tape cassette having apertures formed through one side wall of its casing to accept a magnetic head and a pinch roller. The cassette tape player has a body assembly on which the tape cassette is freely loaded or unloaded and a lid supported by the body assembly so as to be freely rotatable for closing and opening the cassette tape player. The tape cassette is inserted into a loading region of the body assembly by closing the lid. A head assembly chassis is supported by one side end portion of the cassette loading portion so that its moves together with the lid. The head assembly also supports a magnetic head holder and the pinch roller. The tape cassette is supported by securing the upper surface wall of the cassette casing by inserting cassette holding members into the pinch roller insertion openings of the tape cassette. These holding members which are substantially parallel to the inner top wall of the lid support one side of the upper surface wall of the tape cassette while spring members provide opposing pressure to the opposite side of the upper surface wall of the tape cassette. The holding member and spring member combination hold the tape cassette for loading in a compact arrangement to ensure efficient use of space in the cassette tape player.

摘要： A cassette tape recording and/or reproducing apparatus has a head base assembly comprised of a first arm mounted, at one end, on the chassis for swinging about a first axis perpendicular to a plane on which a cassette is located on the chassis, a second arm connected in end-to-end relation to the other end of the first arm by a joint structure permitting relative angular displacements about a second axis parallel to the first axis, and a fixed guide post extending parallel to the plane of the chassis and passing slidably through a slot in the second arm for stabilizing the position of a magnetic head on the second arm in respect to a cassette on the chassis. The joint structure includes a screw defining the second axis and being turnable to relatively displace the connected ends of the arms along that second axis for rocking the second arm about the fixed guide post and thereby varying the aximuth angle of the head.

摘要： A translation cam arrangement comprises a translation cam and an accentric gear rotatably secured to the translation cam, and as the eccentric gear is rotated by a driving gear meshed therewith, the translation cam reciprocates in correspondence with various distances between centers of both the gears. Thus, there is no need of another cam arrangement for moving the translation cam.

摘要： In an auto-reverse type tape recorder also capable of repeatedly playing a tape in both directions, the tape travel is not shut off when the mode of operation is manually changed over from the normal run mode to the reverse run mode, or vice-versa, and after a changeover to the record mode, manual changeover operation is locked-out or made impossible in order to prevent the travel of the tape from being inadvertently changed over and, further, the travel of the tape is stopped without fail at the end of either the normal run mode or the reverse run mode.

摘要： A recording and/or reproducing apparatus of a disc-shaped recording medium includes a main body portion, a shutter mechanism, a drive mechanism, an elevation mechanism and an eject mechanism. The main body portion has an opening portion through which a disc-shaped recording medium is inserted or ejected. The shutter mechanism opens and closes the opening portion. The shutter mechanism is provided on the main body portion to be freely movable and closes the opening portion under a state that the disc-shaped recording medium is completely inserted into the main body portion. The drive mechanism rotatably drivers the disc-shaped recording medium. The elevator mechanism is moved up and down in an interlocking manner with a movement of the shutter mechanism. The elevator mechanism mounts the recording medium on the drive mechanism when the shutter mechanism is moved to a position to close the opening portion, while makes the disc-shaped recording medium apart from the drive mechanism when the shutter mechanism is moved to a position to open said opening portion. The eject mechanism ejects the recording medium from the opening portion. The eject mechanism ejects the disc-shaped recording medium made apart from the drive mechanism by the elevator mechanism from the opening portion when the shutter mechanism is moved from the position to close the opening portion to the portion to open the opening portion.
