  • each cassette may be lowered into playing position by being slid in its main plane, and the apparatus is preferably oriented such that this sliding movement of the cassette occurs vertically downwards between spaced vertical frame plates 36, 38 (FIG. la) from the magazine to the playing position.
  • the bottomless magazine 10 (FIG. 3) is preferably rectangular and formed by longitudinal side walls 40, 42 and end walls 44 and is divided into transverse compartments by means herein shown as partition like elements 46 which project from the vertical side walls 40, 42 of the magazine.

That single cassette is held from falling through the entrance slot 66 by a longitudinal retaining rod 68, the
  • the rod is adjacent one end of the slot so that the cassette starts to fall into the slot when it is brought into operative position above the slot 66 and is held by the rod in such a manner that it tilts away from the adjacent side wall 40 (FIG. 5) ofthe magazine and into leaning engagement with the opposite side wall 42 of the magazine, to insure that upon retraction of the rod 68-the cassette will not stick to the walls of the magazine andwill readily drop through the en trance slot toward the tape transport.

  • vertical guides or grooves 76 (FIG. 1a) adapted to be slidably engaged by the lateral edges of a cassette during its downward movement are mounted on the fixed plate 36 and constrain the cassette movement to a vertical plane.
  • the tape transport includes a movable frame or support 78 (FIG. 1) which carries a drive motor 80 for the capstan 26 and reel drive shafts 20 which comprise the tape and reel drive elements of the tape transport.
  • the support 78 is movable so that the drive elements enter into penetrating engagement with the cassette as the latter moves to playing position.
  • the movable support is carried on the fixed frame 12 by means herein shown as parallelogram links 88 so that the movable support and the elements carried thereby move simultaneously together with and toward the cassette as it moves vertically downward within the guides, and the drive elements enter the cassette (with a linear motion substantially perpendicular relative to the face of the cassette).
  • Means associated with the movable frame of the tape transport also serve to lower the cassette while maintaining it in registration with thetape and reel drive elements so that such elements properly enter the openings in the face of the cassette, said means in this case comprising a pair of pins 90 (FIGS. 1 and 1a) fixed to the movable plate 78 and projecting into the space between the stationary frame plates where they enter tubular members for lugs 92, 94 that project across the vertical path of the cassette and are carried in vertical slots 97, 98 (FIG.
  • each lug 92, 94 is provided with a flange 95, 96 at its base which fit in similar slots 97, 98 in the fixed frame plate 36 so that the lug has straight up and down motion and together the lugs 92, 94 carry the cassette both downward to'the playing position and upward after the playing operation to return it to the magazine at the completion of the change cycle.
  • the tape and reel drive elements on the movable support 78 gradually act on and penetrate the face of the cassette during its lowering movement, and also gradually separate from the cassette during its return movement.
  • the alignment means is shown as a clip 105 (FIGS. 1, l3) fastenedto the movable plate 78 which comes to bear against the edge 106 of a raised projection which is on both main surfaces of the cassette.
  • the alignment clip 105 is carried by the movable plate 78 and is thus gradually moved into engagement with the cassette during the course of its downward movement to the playing position.' Once it moves into engagement with the cassette, it serves as a positive means for positioning the cassette in its final alignment with the tape stretched across the recording and playback heads and pressed against such head by a resilient pressure pad installed for this purpose inside the cassette, the final stage of movement of the cassette being against the opposing force of such resiliently mounted pad.
  • the cassette is carried .upward in the guides 76 by upward movement of the movable tape transport plate 78, and the elevator arm 99 is effective to carry the cassette from the tape transport 11 to the magazine 10, the retaining rod 68 being returned to retain the cassette in the magazine.
  • CHANGER OPERATING MECHANISM In carrying'out the invention, the power to move the components of the changer through the change cycle is provided by linkages operated by motor driven cams A, B and C..As shown in FIG. 1, a motor 101 is fixed to the frame 12. This motor. 101 drives the three cams A, B and C (FIGS. 5,7 and 10) and associated sets of linkages, to coordinatelybut independently operate (1) the cassette retaining means 68 which is effective to hold and release.
  • Cam A is a positively acting face cam formed by a 5 groove 107 in one surface of the member 102.
  • a link 108 is provided having a slot 109 in its upper edge into which the retaining rod 68 fits, and pivoted at its lower 10 end on the pin 110.
  • the link 108 is oscillated to impart the desired motion to the retaining rod by a rocker arm 112 which is also pivoted about the fixed pin and has a follower roller 113 at its lower end which rides in the groove l07 of the cam A.
  • the retaining rod 15 68 is retracted to release the cassette to start the change cycle by motion of the rocker arm 112 produced by the cam A, the retaining rod 68 being returned to block the entrance slot 66 by the completion of 180 of cam A rotation.
  • the link 108 is resiliently connected for movement by the rocker arm 112 by means herein shown in FIG. 8 as a hairspring 114.
  • Said hairspring 114 is wound around a pin 111 and has two arms 114-1, 114-2, which pass through apertures in a flange 115 at the upper edge of the rocker arm 112 CASSETTE TRANSFER MEANS OPERATED BY CAM B As the cassette is dropped from the magazine, it falls onto the cassette transfer means served by the elevator arm 99 (FIG. 12) which is driven by a plate cam B on the opposite surface of the toothed member 102.
  • the elevator arm 99 is moved by a forked link 117 having a follower roller 118 fixed to the link 1'17 intermediate its ends so as to ride on the edge 120 of cam Band pivoted at its right hand end as viewd in FIG. 12 on a pivot 119.
  • Cam B is thus effective followingthe start of the change cycle by means of its rotation to lower the elevator arm 99 and thereby the cassette downward to the tape transport and by rotation of the cam B through during the first portion of the change cycle to move the arm to. its lowermost position (FIG. 13).
  • Cam C is a'face cam formed by a groove 126 in the surface of the gear member 103 and operates a cam follower roller 127 fixed near the left end of the drive link 125 (FIG. 7) which rides in the groove of cam C, the drive link being pivotally mountedat its right hand end.
  • the dwell section provides delay while the cassette is falling from the magazine and being transferred by the elevating arm 99 to the tape transport lugs 92, 94. After the cam C rotates its dwell section past the follower 127, the drive link 125 is driven downwardly by the cam C.
  • the tape transport movable plate 78 initially drops by gravity and accompanies the descent of the drive link 125, the top edge of a slot 128 in the connecting link 124 resting on a pin 129 which extends from the left end of the drive link 125.
  • An interlocking link 130 becomes operative during this phase of the operation (the gravity descent of the cassette and movable tape transport plate) to prevent blocking and damage to the mechanism if, during this phase of the operation, the passages in the cassette do not register with the drive elements carried on the movable plate 78. Such may occur if the cassette is inadvertently placed in the magazine upsidedown, or an obstruction may prevent the cassette from moving together with the movement of the tape trans port by gravity.
  • Non-registration of the passages in the cassette with the drive elements stops the approach movement of the moving plate 78 towards the plane of cassette movement upon the drive elements abutting the outside of the cassette. Since the approach movement of the movable plate 78 is linked with its descending movement the stoppage of one causes stoppage of the other.
  • the drive link 125 is raised by cam C which raises the pin 129 into abutment with the upper edge of slot 128 and thus raises the connecting link 124 to bring the movable plate 78 to its uppermost position freeing the cassette from any interfer ence and allowing the elevator arm 99, responsive to continued rotation of cam B, to raise the cassette and return it to the magazine.
  • the connecting link 124 will descend with the drive link 125 without interruption.
  • the cam C is utilized to positively drive the connecting link downwardly and thereby the movable plate downwardly and into its final playing position with the cassette, assuming the interlock to prevent damage to the mechanism has not come into operation and the cassette is properly registered with the drive elements of the tape transport.
  • this is achieved by utilizing the interlocking link 130 as a means to transmit force from the drive link to positively urge the connecting link 124 and movable plate of the tape transport downward in unison.
  • the interlocking link is pivotally mounted on a pin 131 to the connecting link and is urged counterclockwise as shown in FIG. 7 about its pivot by a resilient spring 132.
  • a pin 133 which projects from the interlocking link 130 into a recess 134 in the fixed vertical frame plate 38 acts as a follower on a cam surface provided by the left vertical edge of the recess.
  • the shape of the edge as shown in FIG. 7a is such that the top section 134-1 of the edge is vertical so that the interlocking link 130 is maintained in its clockwise position as shown in FIG. 7a upon downward movement of said interlocking link with the connecting link 124 at the start of the cassette introduction and movable transport plate movement.
  • the pin 133 rides down the inclined section 134-2 of the recess allowing the link 130 to pivot counterclockwise so that its upper edge 135 is placed under the pin 129 which is carried by the drive link 125 as shown in FIG; 13. Further downward movement of the drive link 125 is effective to positively strike the pin 129 down against the upper edge 135 of the interlocking link 130 to urge the connecting link and movable plate downwardly for the remaining portion of the tape transport plate movement to the. playing position, to positively drive the tape transport movable plate 78 downward during its final increment of motion.
  • the movable plate 78 of the tape transport As the movable plate 78 of the tape transport is driven down by the cam C to lower the cassette into playing position, the plate meets a spring 136 which opposes the final downward movement of the tape transport plate, and stores energy for starting the upward return movement of the plate during the second (cassette return) portion of the change cycle after the cassette has been played.
  • the movable transport plate 78 is latched against the force of the spring 136 by a pawl 137 (FIG.
  • a switch 139 is engaged and opened by the drive link 125 as it is driven by the cam C to its lowermost position; how the control circuit operates will be described in detail below.
  • cam C through the connecting link 124 is also effective to lock the magazine against movement.
  • this is achieved by the connecting link lowering a flat, detent member 142 from a raised position (FIGS. 7, 11) into a lower, locking position (FIG. 13) relative to a magazine locking
