Cassette changer apparatus having priority eject

Claim 2

Record and/or playback apparatus comprising an input supply of magnetic tape cassettes, an output store for said cassettes spaced from said input supply, a record/playback station intermediate said input supply and output store, conveyor means for conveying individual cassettes from said supply to said record/playback station and thence to said output store, a discharge chute for receiving a cassette conveyed from said record/playback station to said output store, an elevator disposed above said discharge chute for receiving a conveyed cassette and lifting same into said output store, said elevator normally being conditioned to intercept said conveyed cassette and prevent same from being received by said discharge chute; and means for selectively displacing said elevator before said conveyed cassette is intercepted thereby; whereby said conveyed cassette is discharged from said apparatus by said chute when said elevator is displaced.

Claim 3

The apparatus of claim 1 wherein said means for displacing said elevator comprises an elevator drive motor; motor control means for selectively energizing said drive motor; and switch means for selectively applying a control signal to said motor control means.

Claim 4

The apparatus of claim 2 wherein said switch means comprises input means for supplying a signal indicating that a cassette to be conveyed from said record/playback station is a "priority" cassette; signal storage means for storing said signal and for producing said control signal in response thereto so as to actuate said motor control means and energize said elevator drive motor; and means for clearing said signal storage means of said signal when said elevator is displaced to deactuate said motor control means and thus de-energize said motor, whereby said elevator remains displaced so that said cassette conveyed from said record/playback station is received by said discharge chute.

Claim 5

The apparatus of claim 3 further comprising system control means for controlling the conveyance of a cassette from said input supply to said record/playback station and from said record/playback station to said output store, said system control means supplying an actuating signal to said motor control means when a cassette is conveyed to said record/playback station so as to return said elevator to said normal condition to intercept a cassette subsequently conveyed from said record/playback station to said output store.

Claim 6

The apparatus of claim 1 wherein said discharge chute is an inclined ramp; and further comprising a storage bin disposed at the bottom portion of said ramp for receiving a cassette that slides down said ramp.

Claim 7

Record and/or playback apparatus having an input supply of magnetic tape cassettes upon which information is recorded and/or reproduced; an output store for said cassettes, said output store spaced from said supply; a record/playback station intermediate said input supply and output store; conveyor means for conveying individual cassettes from said input supply to said record/playback station and thence to said output store; an elevator at said output store, said elevator including a pivotable platform normally inclined to the path of conveyance of said cassettes to receive a cassette conveyed to said output store and to pivot away from said path of conveyance to load said received cassette into said output store; control means for controlling the conveyance of said cassettes and for sensing when a cassette has been conveyed to said record/playback station; a discharge chute positioned adjacent said pivotable platform of said elevator so as to receive a cassette conveyed to said output store when said platform is pivoted away from said path of conveyance, whereby said cassette slides along the length of said chute; an elevator drive motor for pivoting said platform; an elevator motor control circuit for energizing said elevator drive motor in response to an actuating signal applied thereto; input means for selectively applying an actuating signal to said elevator motor control circuit to pivot said platform away from said path of conveyance prior to the time that a cassette is conveyed from said record/playback station to said output store; and means for applying an actuating signal to said elevator control circuit from said control means when a cassette has been conveyed to said record/playback station so as to energize said elevator drive motor to return said platform to its normal inclination to said path of conveyance.

Claim 8

Record and/or playback apparatus having an input supply of magnetic tape cassettes upon which information is recorded and/or reproduced; an output store for said cassettes, said output store spaced from said supply; a record/playback station intermediate said input supply and output store; conveyor means for conveying individual cassettes from said input supply to said record/playback station and thence to said output store; an elevator at said output store, said elevator including a pivotable platform normally inclined to the path of conveyance of said cassettes to receive a cassette conveyed to said output store and to pivot away from said path of conveyance to load said received cassette into said output store; control means for controlling the conveyance of said cassettes and for sensing when a cassette has been conveyed to said record/playback station; a discharge chute positioned adjacent said pivotable platform of said elevator so as to receive a cassette conveyed to said output store when said platform is pivoted away from said path of conveyance, whereby said cassette slides along the length of said chute; an elevator drive motor for pivoting said platform; an elevator motor control circuit for energizing said elevator drive motor in response to an actuating signal applied thereto; input means for selectively applying an actuating signal to said elevator motor control circuit to pivot said platform away from said path of conveyance prior to the time that a cassette is conveyed from said record/playback station to said output store; and means for applying an actuating signal to said elevator control circuit from said control means when a cassette has been conveyed to said record/playback station so as to energize said elevator drive motor to return said platform to its normal inclination to said path of conveyance.
