Abstract
Abstract A cassette-recording apparatus provided with cassette centering pins having a locally thickened portion near their conical ends, and resilient means for pressing the centering edges of the openings in the cassette into engagement with the centering pins. Each of the centering pins comprises two parts which are separated from each other by an axial slit, one of the parts being rigidly connected to the frame of the cassette recorder and the other part being resiliently pressed away therefrom.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
173 words
In a cassette-recording apparatus for use with a cassette having at least one centering opening having a centering edge and comprising a deck plate; at least one cassette-centering pin having a longitudinal axis disposed perpendicular to the plate, and having a base connected to the plate and a tip having a locally thickened portion; and resilient means for urging a portion of the pin and a centering edge of a cassette into engagement with one another, the improved centering pin consisting of a unitary molding wherein the pin is longitudinally split along at least part of its length such that the pin comprises a first part and a second part separated from each other by a longitudinal slit extending through the base of the pin, said first part being rigidly connected to said deck plate; and said resilient means comprises a resilient connection of the second part to the deck plate for pivotally urging said second part away from said first part about an axis remote from and parallel to said longitudinal axis.
Claim 2
Dependent Claim
173 words
In a cassette-recording apparatus for use with a cassette having at least one centering opening having a centering edge and comprising a deck plate; at least one cassette-centering pin having a longitudinal axis disposed perpendicular to the plate, and having a base connected to the plate and a tip having a locally thickened portion; and resilient means for urging a portion of the pin and a centering edge of a cassette into engagement with one another, the improved centering pin consisting of a unitary molding wherein the pin is longitudinally split along at least part of its length such that the pin comprises a first part and a second part separated from each other by a longitudinal slit extending through the base of the pin, said first part being rigidly connected to said deck plate; and said resilient means comprises a resilient connection of the second part to the deck plate for pivotally urging said second part away from said first part about an axis remote from and parallel to said longitudinal axis.
Claim 3
Dependent Claim
34 words
An apparatus as claimed in claim 1, wherein said tip is formed on the first part, and said second part is separated from said tip by a transverse slit communicating with said longitudinal slit.
Claim 4
Dependent Claim
18 words
An apparatus as claimed in claim 2, wherein said locally thickened portion is wholly on said first part.
Claim 5
Dependent Claim
202 words
In a cassette-recording apparatus for use with a cassette having at least one centering opening having a centering edge and comprising a deck plate; at least one cassette-centering pin having a longitudinal axis disposed perpendicular to the plate, and having a base connected to the plate and a tip having a locally thickened portion; and resilient means for urging a portion of the pin and a centering edge of a cassette into engagement with one another, the improved centering pin comprising a first part, a second part and resilient means for urging said second part away from said first part, said first and second parts and resilient means being formed from one unitary molding secured to the deck plate; wherein the pin is longitudinally slit along at least part of its length thereby separating said first and second parts from each other by a longitudinal slit extending through the base of the pin, said first part being rigidly connected to the deck plate; and said resilient means comprises a resilient connection of the second part to the first part for pivotally urging said second part away from said first part about an axis remote from and parallel to said longitudinal said axis.
Claim 6
Dependent Claim
202 words
In a cassette-recording apparatus for use with a cassette having at least one centering opening having a centering edge and comprising a deck plate; at least one cassette-centering pin having a longitudinal axis disposed perpendicular to the plate, and having a base connected to the plate and a tip having a locally thickened portion; and resilient means for urging a portion of the pin and a centering edge of a cassette into engagement with one another, the improved centering pin comprising a first part, a second part and resilient means for urging said second part away from said first part, said first and second parts and resilient means being formed from one unitary molding secured to the deck plate; wherein the pin is longitudinally slit along at least part of its length thereby separating said first and second parts from each other by a longitudinal slit extending through the base of the pin, said first part being rigidly connected to the deck plate; and said resilient means comprises a resilient connection of the second part to the first part for pivotally urging said second part away from said first part about an axis remote from and parallel to said longitudinal said axis.
Claim 7
Dependent Claim
77 words
An apparatus as claimed in claim 4, wherein said resilient means comprises a leaf spring, said second part having a base connected to said leaf spring; said molding comprises a mount having an opening into which said second part is axially movable against force of said leaf spring; and said opening has a size large enough to permit limited movement of said second part transversely of the longitudinal axis when said second part is in said opening.
