Abstract
Abstract Cassette loading apparatus for video machines, the apparatus having a movable housing which carries the cassette into engagement with the tape driving, play back and recording components of the video machine, and a cassette transport mechanism which transports the cassette from its insertion or rest position into the housing, the cassette transport mechanism being self-powered by a drive motor which moves the transport mechanism and thereby the cassette inward from its insertion position to an intermediate position within the housing. The housing is then moved as a unit to carry the cassette into its operative position. A protective door provided on the front edge of the cassette to protect the tape is displaced from the cassette automatically as an incident to movement of the housing to carry the cassette into its operative position, and is returned to the protecting position when the housing returns the cassette from the operative position.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
171 words
In a machine for recording and playing back information on magnetic tape contained in a cassette, a cassette loading apparatus for automatically placing a cassette in operative position with means for driving the tape and components for recording and for playing back recordings on the tape, and for ejecting the cassette, said apparatus comprising: a housing including means for guiding a cassette upon its inward movement edge forward in substantially a single plane from an insertion position to an intermediate position in said housing or its outward movement to said insertion position; means on said machine supporting said housing for movement of a cassette transversely to said plane between its intermediate position and its operative position; and cassette transport mechanism movably mounted on said housing, including a drive unit and means operated by said drive unit and cooperating with means on said housing for moving said transport mechanism including said drive unit, to transport a cassette inward to its intermediate position or to transport the cassette outward to its insertion position.
Claim 2
Dependent Claim
171 words
In a machine for recording and playing back information on magnetic tape contained in a cassette, a cassette loading apparatus for automatically placing a cassette in operative position with means for driving the tape and components for recording and for playing back recordings on the tape, and for ejecting the cassette, said apparatus comprising: a housing including means for guiding a cassette upon its inward movement edge forward in substantially a single plane from an insertion position to an intermediate position in said housing or its outward movement to said insertion position; means on said machine supporting said housing for movement of a cassette transversely to said plane between its intermediate position and its operative position; and cassette transport mechanism movably mounted on said housing, including a drive unit and means operated by said drive unit and cooperating with means on said housing for moving said transport mechanism including said drive unit, to transport a cassette inward to its intermediate position or to transport the cassette outward to its insertion position.
Claim 3
Dependent Claim
30 words
In a machine, cassette loading apparatus according to claim 1 further including means on said machine supporting said housing for movement transversely to said plane of movement of a cassette.
Claim 4
Dependent Claim
95 words
In a machine, cassette loading apparatus according to claims 1 or 2, further including means on said housing engaged by a cassette during inward transport by said transport mechanism for stopping the cassette in its intermediate position, and means operated by said drive unit and cooperating with means on said housing for continuing to move said transport mechanism and separate the latter from the cassette and from mechanical interference with said driving means for the tape or other components of the machine upon transverse movement of said cassette from its intermediate to its operative position.
Claim 5
Dependent Claim
42 words
In a machine, cassette loading apparatus according to claims 1 or 2, wherein said housing includes sidewalls extending transversely to said plane of movement of a cassette which have means for guiding said cassette transport mechanism throughout the path of its movement.
Claim 6
Dependent Claim
53 words
In a machine, cassette loading apparatus according to claim 1 or 2, wherein said drive unit includes a drive motor and said means operated by said drive unit and cooperating with means on said housing includes a pinion and cooperating rack for moving said transport mechanism under the power of said drive motor.
Claim 7
Dependent Claim
43 words
In a machine, cassette loading apparatus according to claim 4, wherein said guide means for said cassette transport mechanism includes a groove in said side walls of said housing, and said rack is located adjacent and follows a similar path as said groove.
Claim 8
Dependent Claim
21 words
In a machine, cassette loading apparatus according to claim 6 wherein said path of said groove and said rack is L-shaped.
Claim 9
Dependent Claim
25 words
In a machine, cassette loading apparatus according to claim 4 wherein said guide means supports said cassette transport mechanism for movement along an L-shaped path.
Claim 10
Dependent Claim
40 words
In a machine, cassette loading apparatus according to claim 8, wherein said guide means includes grooves in said sidewalls of said housing, and said cassette transport mechanism includes a shaft guided by said grooves and operated by said drive motor.
Claim 11
Dependent Claim
59 words
In a machine, cassette loading mechanism according to claim 9 wherein said cassette transport mechanism includes members guided in said grooves carrying rollers which are engaged by the front edge of the cassette, in carrying the cassette during its inward and outward movement in said plane, when the cassette loading apparatus is oriented such that said plane is vertical.
Claim 12
Dependent Claim
48 words
In a machine, cassette loading apparatus according to claim 3, further including means for engaging the cassette and moving said cassette relative to said stopping means and cooperating with means on said machine to unlock a door in the front edge of the cassette protecting the magnetic tape.
Claim 13
Dependent Claim
59 words
In a machine, cassette loading apparatus according to claim 11, wherein said means for engaging and moving said cassette includes a lever mounted for pivotal movement in two directions and having a pin adapted to penetrate into the cassette upon lever movement in one of said directions and to move said cassette upon lever movement in the second direction.
Claim 14
Dependent Claim
37 words
In a machine, cassette loading apparatus according to claim 11, including means for pivoting said lever in said two directions responsive to the movement of said transport mechanism transverse to said plane of movement of the cassette.
Claim 15
Dependent Claim
28 words
In a machine, cassette loading apparatus according to claim 11, wherein said means for engaging and moving said cassette is operable before said cassette reaches the intermediate position.
Claim 16
Dependent Claim
47 words
In a machine, cassette loading apparatus according to claim 1, moving the cassette within a cubic volume having corresponding dimensions not more than a third greater than the length and width of the cassette nor having a depth greater than about twice the thickness of the cassette.
