    摘要： A cassette-type magnetic tape recording and/or reproducing apparatus is comprised of a rotary drum unit having a magnetic head or heads for recording or reproducing signals on a magnetic tape, a loading device movable between a first position and a second position by the operation of a single electric motor, a tape guide device responsive to movement of the loading device to extract the tape from a cassette and to guide the tape by being moved between an inoperative position and an operative position in which a preset tape path is defined in proximity to the drum device, and a pinch roller operating device also associated with the loading device for pressing the pinch roller against the capstan or disengaging the pinch roller from the capstan.

    摘要： A recording and/or reproducing apparatus for recording and/or reproducing signals on and/or from a recording medium includes a recording and/or reproducing portion for recording and/or reproducing signals on and/or from the recording medium, a carrying portion for carrying the recording medium, and first and second sliders. The first slider is movable in one direction for moving the carrying portion together with the recording medium up to a specific withdrawal position. The second slider is movable in a direction being substantially the same as the one direction for moving the recording medium carried by the carrying portion to a recording and/or reproducing position corresponding to a position of the recording and/or reproducing portion. The first slider and the second slider are overlapped to each other in the vertical direction.

    摘要： A disk centering apparatus includes a disk table member and a movable member. An inner circumferential portion of the disk table member is secured to an upper portion of a motor shaft. An outer circumferential portion of a greater diameter is disposed lower than an upper surface of and concentrically with the inner circumferential portion and has an upper surface for receiving a disk thereon. Connecting portions extend radially outwardly from the inner circumferential portion. The movable member includes a supported shaft portion mounted for sliding movement on the motor shaft and disposed lower than the disk table member. A guiding portion is provided adjacent an outer surface side of the supported shaft portion and includes a guiding inclined portion formed at an upper portion thereof and a diameter greater than the inner circumference portion. The movable member is biased upwardly in a direction of the motor shaft.
