Abstract: A magnetic tape loading mechanism for a magnetic recording and/or reproducing apparatus is disclosed. The loading mechanism includes a reversible driving motor which can be actuated by signals sent from a positional detector to drive a gear train in order to perform a switching operation of work modes. The gear train includes five actuating gears which are operatively connected to the corresponding members, such as a pair of mounting blocks each having an inclination post and a guide roller provided thereon, a moving post, a tension post and a pinch roller, so that these members can be moved to a predetermined position according to the various time sequences and work modes, to enable the magnetic tape to be led out of a tape cassette located in the apparatus and to be wound around a magnetic head having a magnetic drum, thereby allowing to record or reproduce signals from the magnetic tape.

Abstract: A cassette loading mechanism comprising a movable plate-like member which is maintained on the same plane with a stationary plate-like member and slidable relative to the stationary member. A symmetrical four bar linkage is connected between the two members. The movable member is moved, under the guidance of fixed shaped slots, with a cassette holder into which a cassette is inserted between an unloading position and a loading position by an actuation device acting at one side of the cassette holder. The four bar linkage transmits the actuation to the other side of the cassette holder in a substantially synchronous way to make both sides of the cassette holder move symmetrically and synchronously and thus reducing the risk of jamming.

Abstract: A tape loading device for a magnetic tape recording and/or reproducing apparatus, characterized in a mechanism having slidable plates and linkages for urging movable guide posts, movable blocks, guide rollers, a pinch roller, a tension post, and reel brakes in order to extract a length of magnetic tape from a magnetic tape cassette and moving the length of magnetic tape to various positions corresponding to various operation modes of the tape loading device.
