Abstract
A cassette tape recorder in which a supply turntable and a take-up turntable supported by a base are respectively disposed for rotating engagement with a pair of hubs in a cassette, and a pinch roller and magnetic heads are disposed on the base on the front wall side of the cassette for recording and reproducing engagement with a magnetic tape. An actuating push button group including a play button is pivoted to the base on the rear wall side of the cassette by a pivot extending beneath the base. In response to the depression of the play button, the pinch roller and magnetic heads are advanced toward the cassette, and the tape is fed in the take-up direction at a predetermined take-up speed.
Claims8
A cassette tape recorder of the kind using a cassette including a housing which has an upper wall, a lower wall, a front wall, a rear wall, and a pair of side walls, and in which a magnetic tape wound around one of a pair of hubs supported freely rotatably between the upper and lower walls with one end thereof fixed to that hub is guided toward the other hub along a path extending adjacent to a plurality of openings bored in the front wall to be wound around the other hub with the other end thereof fixed to the latter hub, the tape being adapted to be fed at a predetermined take-up speed during recording and reproduction, comprising:
- a base;
- a supply turntable and a take-up turntable mounted freely rotatably to said base and having a center-to-center distance equal to that of said hubs in said cassette;
- means mounted to said base for positioning and maintaining said cassette in a predetermined cassette mounting position such that said cassette is positioned with its front wall directed toward the rear side of said base and said hubs are brought into rotating engagement with said supply and take-up turntables respectively;
- a slide member arranged for sliding movement and carrying at least a recording-reproducing head and a pinch roller at positions opposite to the openings in the front wall of said cassette maintained in the predetermined cassette mounting position;
- guide means mounted on said base member with respect to guide slots formed in said slide member for guiding said slide member in its movement toward and away from the front side of said base;
- spring means for biasing said slide member away from the front side of said base to hold said recording-reproducing head and said pinch roller spaced from said cassette;
- a pivot disposed beneath said base on the rear wall side of said cassette;
- a play button lever pivoted to said pivot for swinging movement around said pivot, said play button lever including an outwardly protruding portion mounted to a play button and an upwardly extending portion extending upwardly through a slot in said base and a slot formed in said slide member, whereby said upwardly extending portion contacts said slide member and presses said slide member toward the front side of said base to bring the at least one recording-reproducing head and pinch roller into an operative position in response to depression swinging movement of said play button against the biasing force of said spring means;
- and
- means for feeding said tape at the predetermined take-up speed toward said take-up turntable by operating in interlocking relation with the swinging movement of said play button.
A cassette tape recorder of the kind using a cassette including a housing which has an upper wall, a lower wall, a front wall, a rear wall, and a pair of side walls, and in which a magnetic tape wound around one of a pair of hubs supported freely rotatably between the upper and lower walls with one end thereof fixed to that hub is guided toward the other hub along a path extending adjacent to a plurality of openings bored in the front wall to be wound around the other hub with the other end thereof fixed to the latter hub, the tape being adapted to be fed at a predetermined take-up speed during recording and reproduction, comprising:
- a base;
- a supply turntable and a take-up turntable mounted freely rotatably to said base and having a center-to-center distance equal to that of said hubs in said cassette;
- means mounted to said base for positioning and maintaining said cassette in a predetermined cassette mounting position such that said cassette is positioned with its front wall directed toward the rear side of said base and said hubs are brought into rotating engagement with said supply and take-up turntables respectively;
- a slide member carrying at least a recording-reproducing head and a pinch roller at positions opposite to the openings in the front wall of said cassette maintained in the predetermined cassette mounting position, said slide member extending on said base from the area adjacent to the front wall of said cassette beyond the area including said supply and take-up turntables;
- first guide means including guide members mounted on said base member with respect to guide slots formed in said slide member and for guiding said slide member toward and away from the front side of said base;
- first spring means for biasing said slide member away from the front side of said base to hold said recording-reproducing head and said pinch roller spaced from said cassette;
- a brake member disposed above said slide member and extending substantially between said turntables and the rear wall of said cassette;
- second guide means for guiding said brake member toward and away from said supply and take-up turntables;
- second spring means for biasing said brake member toward said turntables to make braking engagement therewith;
- a pivot disposed beneath said base on the rear wall side of said cassette;
- a play button lever pivoted to said pivot for swinging movement around said point, said play button lever including an outwardly protruding portion mounted to a play button and a portion extending upwardly through a slot in said base and a slot formed in said slide member and a slot formed in said brake member, whereby said upwardly extending portion contacts said slide member and said brake member and presses said slide member and said brake member toward the front side of said base to bring the at least one recording-reproducing head and pinch roller into an operative position in response to depression swinging movement of said play button against the biasing forces of said first and second spring means;
- and
- means for feeding said tape at the predetermined take-up speed toward said take-up turntable by operating in interlocking relation with the swinging movement of said play button.
