Definitions

  • Movement of the linkage into the second position also engages a roller with the cartridge and moves it into a locked position within the player.
  • a solenoid is energized to actuate the overcenter spring to bias the linkage back to the first position for ejecting the cartridge.
  • This invention pertains generally to a cartridge locking and ejector mechanism and more particularly to such a mechanism for a cartridge-type tape player.
  • a linkage is pivotally mounted to the tape player and has an actuating arm integral therewith that extends into the chamber receiving the cartridge.
  • the linkage is connected to one end of an overcenter spring which is used to bias it between first and second stable positions.
  • the other end of the overcenter spring is either fixed to the player for manual operation or is coupled to the armature of the solenoid for automatic operation.
  • a roller connected to the linkage engages a groove in the cartridge and moves the cartridge with the linkage to position the same so that the tape is firmly pressed against the player capstan shaft.
  • a solenoid is energized to once again actuate the overcenter spring to bias the linkage from the second stable position to the first stable position thereby moving the roller and actuating arm, resulting in the cartridge being ejected from the player.
  • FIG. 1 is a front elevation view showing the tape player apparatus in accordance with this invention
  • FIG. 2 is a top plan view of the device of FIG. 1;
  • FIG. 3 is a top plan view similar to FIG. 2 showing a tape cartridge in position in the device;
  • FIG. 4 is a top plan view of a portion of the mechanism shown in FIGS. 2 and 3 and illustrates a second embodiment of this invention.
  • FIG. 5 is a schematic wiring diagram illustrating automatic operation of the device in accordance with this invention.
  • FIG. 1 shows a tape player apparatus 10 that is adapted to receive and play tape cartridges such as 12 (FIG. 3) having a 'multi-track tape therein which is positioned to be engaged by the capstan shaft 14 to drive the tape through the cartridge 12.
  • An electric motor 16 drives a pulley 18 which is connected through a belt 20* the capstan flywheel 22.
  • a miniature switch 24 is responsive to the placing of cartridge 12 in the cartridge receiving chamber 25 of the tape player to energize the motor 16.
  • a magnetic tape reproducing head 28 is positioned by cam follower 30 riding on a cam 32, which has a plurality of ca-m surfaces such as 34.
  • a conductive strip on the tape bridges the contacts 36 to energize a solenoid 38 which operates a linkage 40 toposition the cam 32 so that a difierent cam surface engages the cam follower 30. This repositions the magnetic tape head 28 to play a different set of tracks on the tape.
  • the mechanism comprises a linkage including a first arm or bell crank 47 which is pivotally mounted to the top plate 42 by rivet 49. Extending from arm 47 is actuating memher or projection 51. The projection 51 extends down into the cartridge receiving chamber 25 as shown in FIG. 1.
  • the linkage includes a second ar-m member 53 which is pivotally mounted to the top plate 42 by rivet 55.
  • An overcenter spring 57 has one end connected by spring post 59 to the arm 53. The other end is connected to spring post 61 which is mounted to link 63. Link 63 in turn is pivotally mounted at 65 to the top plate 42.
  • a solenoid 68 is mounted to the player 10 and has an armature arm 70 thereof coupled to link 63.
  • the rivet 72 is fixed to the plate 42 and moves in slot 74 of the armature 70 to guide the armature in a straight fore and aft path during movement thereof.
  • a slot 75 is located in the armature 70 and receives rivet 77 which is fixed to the link 63. With this arrangement, fore and aft movement of armature 70 is translated by the rivet 77 and slot 75 into rotational movement.
  • the overcenter spring 57 is used to bias the linkage consisting of arm 53 and arm 47 into first and second stable positions.
  • the first stable position is shown in FIG. 2.
  • motion of the arm '53 causes the spring post 59 to move to a point past the center of spring 57 such that the spring will snap to the position shown in FIG. 3 thereby biasing the arms 53 and 47 of the linkage to the second stable position.
  • the ejection mechanism is initially in the first stable position as shown in FIG. 2.
  • the tape cartridge When the tape cartridge is inserted into the chamber 25, it moves in a direction towards the rear of the player until the leading edge 80 of the cartridge 12 strikes the actuating member 51.
  • the cartridge 12 in engagement with actuating member 51 causes arm 47 to pivot about rivet 49.
  • arm 47 pivots As arm 47 pivots, it moves with its arm 53 about pivot 55.
  • the end of the overcenter spring on post '59 reaches a position where the spring tension on each arm of the spring 57 will become unbalanced and it will snap to a position as shown in FIG. 3.
  • the roller 82 which is rotatably mounted to the arm 53, engages a V groove or slot 85 (FIG. 3) in cartridge 12. Now when the arm 53 is snapped by the spring 57 to the position shown in FIG. 3, the roller 82 will be engaged with the slot 85 and move the cartridge with it. With the linkage biased to the second stable position, the roller 82 urges the cartridge 12 all the way forward in the chamber 25 and holds it in this position. In this position, the pinch roller 90 (FIG. 3) which is mounted in the cartridge 12 will press against the capstan shaft 14 to capture the tape between the roller and the shaft. Therefore, as the cap stan shaft turns, it rotates the pinch roller to drive the magnetic tape therebetween past the magnetic head 28 to reproduce the sound.
  • Energizing solenoid 68 pulls armature 70 into the solenoid as shown in FIG. 2.
  • This straightline movement of the armature 70 is translated by the link '63 as previously explained into rotational movement pulling post 61, to which one end of the overcenter spring 57 is connected, in the counter clockwise direction as viewed in FIG. 3.
  • Motion of arm '53 to the first stable position removes the roller 82 from the V groove 85 in the cartridge and also causes arm 47 to snap into the position shown in FIG. 2.
  • FIG. 4 shows an embodiment which provides for manual operation of the locking and ejecting mechanism.
  • the spring posts 61a is fixed to the plate 42a of the tape player instead of being connected to the arm 63.
  • the other end of the spring 57a is connected to post 59a which is mounted to the arm 53a in the same manner as is post 59.
  • Apparatus using an exchangeable cartridge including in combination, linkage means, overcenter spring means coupled to said linkage means for biasing the same to first and second stable positions, actuator means coupled to said linkage means and being responsive to a cartridge moving in the apparatus to move said linkage means from said first stable position to actuate said overcenter spring means to bias said linkage means to said seconds table position, ejector means coupled to said overcenter spring means for actuating the same to bias said link age means from said second stable position to said first stable position, and means coupled to said linkage means for engaging the cartridge to move the same with said linkage means being moved between said first and second stable positions.
