Abstract
Abstract Cassette tape recorder for use with a tape cassette having openings for receiving the magnetic heads and the pinch roller at its front side wall and openings for receiving the tape reel driving shafts and the capstan at its upper and lower walls. The tape recorder has a spring biased cassette loading plate movable together with the cassette loaded thereon in the direction parallel to the axes of the reel driving shafts and the capstan toward the inside of the tape recorder with the plane of the cassette loading plate positioned perpendicular to the direction of the movement thereof thereby permitting the cassette to be latched in the operative position engaging with the reel driving shafts and the capstan by latching guide pins of the tape recorder. The magnetic heads and the pinch roller are mounted on a mounting member which is so coupled with the cassette loading plate by coupling means that the magnetic heads and the pinch roller are moved substantially perpendicular to the movement of the cassette loading plate at about the end thereof in the direction toward the openings in the front side wall of the cassette loaded on the cassette loading plate so as to be brought in their operative positions with the tape in the cassette.

Claim 1
Independent Claim
417 words
In a combination of an automobile radio and cassette tape recorder, said radio and recorder having a common casing including a front panel, said panel carrying operating knobs for said radio and being formed with an aperture for receiving a tape cassette having a first wall formed with openings for receiving magnetic heads and a pinch roller of the tape recorder, openings in at least one second wall transverse to said first wall for receiving tape reel driving shafts and a capstan, and guide holes in said at least one second wall for receiving latching guide pins of the tape recorder, the improvement which comprises: a. a base plate carrying said tape reel driving shafts and said capstan, said base plate being inwardly offset in said casing from said front panel; b. a flywheel operatively connected to said capstan for rotation of said flywheel with said capstan; c. a cassette loading plate mounted on said base plate for movement parallel to the axes of said tape reel driving shafts and said capstan, 1. said cassette loading plate extending in a plane transverse to said axes; d. spring means operatively interposed between said cassette loading plate and said base plate for biasing said cassette loading plate away from an operative position adjacent said base plate and in a direction outward of said casing through said aperture; e. latching guide pins mounted on said base plate for engaging said guide holes in a cassette loaded on said cassette loading plate when the cassette is moved inwardly of said casing together with said cassette loading plate, and for releasably latching said cassette in the operative position of said cassette loading plate while said tape reel driving shafts and said capstan respectively engage tape reels and a tape in said cassette; f. a lever member carrying said magnetic heads and said pinch roller; g. pivot means connecting said lever member to said base plate from movement of said magnetic heads and said pinch roller transversely to the direction of movement of said cassette loading plate toward and away from said openings in said first wall; and h. means coupling said cassette loading plate to said lever member for moving the lever member in timed sequence with the movement of the cassette loading plate, and for thereby causing said magnetic heads and said pinch roller to be received in said openings in the first wall of a cassette loaded on said cassette loading plate when the latter enters said operative position thereof.
Claim 2
Dependent Claim
417 words
In a combination of an automobile radio and cassette tape recorder, said radio and recorder having a common casing including a front panel, said panel carrying operating knobs for said radio and being formed with an aperture for receiving a tape cassette having a first wall formed with openings for receiving magnetic heads and a pinch roller of the tape recorder, openings in at least one second wall transverse to said first wall for receiving tape reel driving shafts and a capstan, and guide holes in said at least one second wall for receiving latching guide pins of the tape recorder, the improvement which comprises: a. a base plate carrying said tape reel driving shafts and said capstan, said base plate being inwardly offset in said casing from said front panel; b. a flywheel operatively connected to said capstan for rotation of said flywheel with said capstan; c. a cassette loading plate mounted on said base plate for movement parallel to the axes of said tape reel driving shafts and said capstan, 1. said cassette loading plate extending in a plane transverse to said axes; d. spring means operatively interposed between said cassette loading plate and said base plate for biasing said cassette loading plate away from an operative position adjacent said base plate and in a direction outward of said casing through said aperture; e. latching guide pins mounted on said base plate for engaging said guide holes in a cassette loaded on said cassette loading plate when the cassette is moved inwardly of said casing together with said cassette loading plate, and for releasably latching said cassette in the operative position of said cassette loading plate while said tape reel driving shafts and said capstan respectively engage tape reels and a tape in said cassette; f. a lever member carrying said magnetic heads and said pinch roller; g. pivot means connecting said lever member to said base plate from movement of said magnetic heads and said pinch roller transversely to the direction of movement of said cassette loading plate toward and away from said openings in said first wall; and h. means coupling said cassette loading plate to said lever member for moving the lever member in timed sequence with the movement of the cassette loading plate, and for thereby causing said magnetic heads and said pinch roller to be received in said openings in the first wall of a cassette loaded on said cassette loading plate when the latter enters said operative position thereof.
Claim 3
Dependent Claim
85 words
In a combination as set forth in claim 1, said front panel said front panel being having a length greater than the width thereof, said casing having a front portion adjacent said top and bottom panels substantially equal in width to said front panel, and a major portion remote from said front panel having a width substantially smaller than the width of said front portion, said flywheel being arranged in said front portion for rotation in a plane extending in the direction of said width.
Claim 4
Dependent Claim
43 words
In a combination as set forth in claim 1, said casing having substantially parallel top and bottom panels obliquely inclined relative to said front panels, said flywheel being mounted in said casing for rotation in a plane substantially parallel to said front panel.
Claim 5
Dependent Claim
40 words
In a combination as set forth in claim 1, said spring means biasing said cassette loading plate from said operative position toward a position in which said cassette loading plate extends approximately in a common plate with said front panel.
Claim 6
Dependent Claim
62 words
In a combination as set forth in claim 1, a Cassette receiving pocket mounted on said front panel outside said casing under said aperture for receiving a cassette discharged from said casing when the cassette is released by said magnetic heads and said pinch rollers and said cassette loading plate is moved away from the operative position thereof by said spring means.
Claim 7
Dependent Claim
19 words
In a combination as set forth in claim 1, said base plate being substantially parallel to said front panel.
