Abstract

Abstract A cassette tape player suitable for use in automobile audio systems is provided. A receptacle for a cassette is movably mounted in a chassis at an angle with respect to the chassis bottom. A guide mechanism serves to first translate the receptacle in the oblique position and then turn the receptacle about its trailing edge to place the receptacle in a horizontal position. The guide is designed such that the capstan receiving opening in the cassette in the receptacle is maintained in constant alignment with the capstan during change of the receptacle from the oblique to the horizontal position, avoiding cassette damage and capstan deformation. Electric controls are accommodated in the space between the receptacle and the chassis bottom.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 278 words
A cassette tape player comprising a chassis having upper and bottom surfaces, a capstan extending downward from the upper surface of the chassis, a box-like receptacle for receiving a cassette therein, movably mounted in the chassis at an oblique position with respect to the chassis bottom, the trailing edge of said receptacle being more remote from the chassis bottom than the leading edge, and guide means for first translating the receptacle in the oblique position, and then turning the receptacle approximately about its trailing edge to place the receptacle in a position parallel to the chassis bottom, said guide means including, at least one pair of guide grooves each formed in the chassis and consisting of a first portion extending parallel to the chassis bottom and a second portion following the first portion and forming an angle slightly larger than 90° with the first portion, and at least one pair of guide members mounted on either side of said cassette receptacle and mated with said pair of guide grooves, wherein when said guide member reaches the intersection between the first and second portions of said guide grooves, the cassette in the receptacle is positioned with its capstan receiving opening aligned with the capstan, and when said guide member is advanced along the second portion to pivot the cassette receptacle from the oblique position to the parallel position, the capstan receiving opening of the cassette is maintained in alignment with said capstan, said guide means being such that the capstan receiving opening in the cassette in said receptacle is maintained in constant alignment with said capstan during turning of the receptacle from the oblique position to the parallel position.
Claim 2
Dependent Claim 278 words
A cassette tape player comprising a chassis having upper and bottom surfaces, a capstan extending downward from the upper surface of the chassis, a box-like receptacle for receiving a cassette therein, movably mounted in the chassis at an oblique position with respect to the chassis bottom, the trailing edge of said receptacle being more remote from the chassis bottom than the leading edge, and guide means for first translating the receptacle in the oblique position, and then turning the receptacle approximately about its trailing edge to place the receptacle in a position parallel to the chassis bottom, said guide means including, at least one pair of guide grooves each formed in the chassis and consisting of a first portion extending parallel to the chassis bottom and a second portion following the first portion and forming an angle slightly larger than 90° with the first portion, and at least one pair of guide members mounted on either side of said cassette receptacle and mated with said pair of guide grooves, wherein when said guide member reaches the intersection between the first and second portions of said guide grooves, the cassette in the receptacle is positioned with its capstan receiving opening aligned with the capstan, and when said guide member is advanced along the second portion to pivot the cassette receptacle from the oblique position to the parallel position, the capstan receiving opening of the cassette is maintained in alignment with said capstan, said guide means being such that the capstan receiving opening in the cassette in said receptacle is maintained in constant alignment with said capstan during turning of the receptacle from the oblique position to the parallel position.
Claim 3
Dependent Claim 82 words
A cassette tape player according to claim 1 wherein said guide means further includes a pair of guide tracks each formed in a spring-biased member pivoted to the chassis bottom, and a pair of guide rollers pivoted on either side of said cassette receptacle and mated with said pair of guide tracks, whereby said spring-biased member urges said guide roller toward the chassis upper surface to turn the cassette receptacle to the parallel position after said guide member has reached said intersection.
Claim 4
Dependent Claim 22 words
A cassette tape player according to claim 2 which further comprises means for spring biasing said cassette receptacle to an initial position.
Claim 5
Dependent Claim 59 words
A cassette tape player according to claim 3 which further includes an eject lever capable of exerting sufficient force to overcome the biasing force of said spring-biased member to turn the cassette receptacle from the parallel position to the oblique position, thereby allowing the the cassette receptacle to be returned to the initial position by said spring biasing means.
Claim 6
Dependent Claim 31 words
A cassette tape player according to claim 1 which further comprises electric controls and indicators disposed between the trailing edge of said cassette receptacle and the bottom surface of said chassis.
Claim 7
Dependent Claim 25 words
A cassette tape player according to claim 5 wherein said electric controls and indicators include a power switch, a volume control and a pilot lamp.
