摘要： In a magnetic recording/reproducing apparatus having a support which reciprocates between reproduce and stop positions and is biased by a spring in the direction of the reproduce position, a magnetic head which is mounted such that it contacts with a magnetic tape at the reproduce position and disengages from the magnetic tape at the stop position. The head is mounted on the support and a pinch roller is mounted where it can be depressed against a capstan at the reproduce position. The pinch roller is removed from the capstan at the stop position on the support or on a deck. The pinch roller is also biased by a spring in the direction of the capstan. The reproducing apparatus has a magnetic body actuator which mechanically actuates a mechanism which slightly moves the support from the reproduce position to the stop position side to a desired degree so that the magnetic head keeps a slight contact with the magnetic tape and disengages the pinch roller from the capstan. An electromagnetic apparatus latches and holds the magnetic body actuator by magnetic force. A mechanism extinguishes the electromagnetic force by electric signals from a non-signal zone detecting circuit which detects the non-signal zones of the magnetic tape.

摘要： In a mode changeover apparatus for a magnetic recorder/player having a plurality of push-buttons for directing changeover of tape drive modes, a simple and compact mechanism for effecting mode changeover including an eccentric idler, a restraining mechanism, a locking mechanism, an engaging mechanism a locking member, a lever, a releasing mechanism and a holding mechanism. The idler is mounted on a slidable support, and can be rotated through a capstan wheel which is driven by a motor. The support carries a magnetic head, and can be moved by the rotation of the idler. The restraining mechanism restrains the support to a reproduction position. The support is moved to a non-reproduction position through the engaging mechanism and is locked there by the locking mechanism. The releasing mechanism releases the support from the non-reproduction locking. The idler is locked to a state that its smallest radius portion confronts the capstan wheel by the locking member. A small gap can be left between this smallest radius portion and the capstan wheel by the holding mechanism. The idler can be brought into rotating relationship with the capstan wheel by the lever which temporarily releases locking engagement for the idler.Alternatively, a slidable bar, a lever pivoted to an end of the bar, electric switches and a control circuit for a motor are provided. One of the switches is operated by the movement of the bar to shut off and allow current supply for the motor. The other switches are operated by the movement of the lever to control the rotational direction and speed of the motor through the control circuit.

摘要： An apparatus is provided for turning a rotor for each desirable angle by a capstan drive system wherein an eccentric free travelling ring carried by a turnable lever at a point removed from the pivot end of the lever is thus contactable and discontactable with a rotary shaft of the capstan drive system. A small gear is connected to the free travelling ring and is engaged with another large rotor gear for reducing the rotation thereof, the large gear being pivotally mounted on the pivot bearing of the turntable lever. Means are provided for biasing the free travelling ring toward the rotary shaft of the capstan drive system and further control means are provided for interlocking the free end of the turntable lever so as to prevent contact of the free travelling ring with the rotary shaft of the capstan drive system.
