Cassette insertion/ejection apparatus

A cassette insertion/ejection apparatus using a cassette in the form of a housing comprising a top face, a bottom face, a front side face, a rear side face, a left-hand side face and a right-hand side face, in which a pair of hubs are rotatably supported between said top and bottom faces and a roll of tape wound about one of said hubs with its one end fixed to said one hub is extended near and parallel to the openings in said front side face and wound about the other hub with its other end fixed to said other hub;

• in which said top and bottom faces have in their central portions near said openings in said front side face a top and a bottom alto-relievo planes, a sloping plane connecting said top alto-relievo plane with said top face and another sloping plane connecting said bottom alto-relievo plane with said bottom face;
• and in which a pair of cassette locating holes and a pair of capstan receiving holes are cut correspondingly in each of said top and bottom alto-relievo planes, said apparatus serving to set said cassette to the proper operation position and to eject the same from said position and comprising;
• 1. a base member;
• 2. a fixed member fixed to said base member and having a sloping plate rising from front to rear side;
• 3. a supply and a take-up turntables rotatably supported on said sloping plate and separated from each other by a distance equal to that between said hubs of said cassette;
• 4. a group of manipulation levers including an eject lever, disposed in front of said base member;
• 5. a cassette tray for carrying said cassette thereon with said rear side face facing said group of said manipulation levers, said cassette tray being swingable between the proper operation position in which said turntables are received in said hubs of said cassette and the quasioperation position which is separated from said proper operation position by a certain angle about an axis near said group of said manipulation levers;
• 6. a pair of stabilizing means for stably locating said cassette tray in said proper operation position and said quasi-operation position, said stabilizing means bringing said cassette tray in said quasi-operation position into said proper operation position by rotating said tray by the urging force with which said cassette is pressed against said cassette tray and also bringing said cassette tray in said proper operation position into said quasi-operation position in accordance with the actuation of said eject lever;
• and
• 7. a cassette lift-up member having a cassette lift-up arm which abuts against said bottom face of said cassette when said cassette tray is kept in said proper operation position by said stabilizing means and can be rotated up from said position about a certain axis near said manipulation levers, which rotates said cassette lift-up arm a little farther than said cassette tray to lift-up said cassette when said cassette tray rotates from said proper operation position to said quasi-operation position, so that said cassette may slide down guided by said arm, and which then stops said cassette sliding down by engaging said arm with said bottom sloping plane of said cassette.

• in which said top and bottom faces have in their central portions near said openings in said front side face a top and a bottom alto-relievo planes, a sloping plane connecting said top alto-relievo plane with said top face and another sloping plane connecting said bottom alto-relievo plane with said bottom face;
• and in which a pair of cassette locating holes and a pair of capstan receiving holes are cut correspondingly in each of said top and bottom alto-relievo plane, said apparatus serving to set said cassette to the proper operation position and to eject the same from said position and comprising:
• 1. a base member;
• 2. a front panel attached to said base member and having a cassette insert/eject opening and a plurality of perforations below said opening;
• 3. a fixed member fixed to said base member and having a sloping plate rising from front to rear side;
• 4. a supply and a take-up turntables rotatably supported on said sloping plate and separated from each other by a distance equal to that between said hubs of said cassette;
• 5. a group of manipulation levers including an eject lever, disposed in front of said base member and extended outside said front panel through said perforations of said panel;
• 6. a cassette tray for carrying said cassette thereon with said rear face facing said group of said manipulation levers, said cassette tray being swingable between the proper operation position in which said turntables are received in said hubs of said cassette and the quasioperation position which is separated from said proper operation position by a certain angle about an axis near said group of said manipulation levers;
• 7. a pair of stabilizing means for stably locating said cassette tray in said proper operation position and said quasi-operation position, said stabilizing means bringing said cassette tray in said quasi-operation position into said proper operation position by rotating said tray by the urging force with which said cassette is pressed against said cassette tray and also bringing said cassette tray in said proper operation position into said quasi-operation position in accordance with the actuation of said eject lever;
• and
• 8. a cassette lift-up member having a cassette lift-up arm which abuts against said bottom face of said cassette when said cassette tray is kept in said proper operation position by said stabilizing means and can be rotated up from said position about a certain axis near said manipulation levers, which rotates said cassette lift-up arm a little further than said cassette tray to lift-up said cassette when said cassette tray rotates from said proper operation position to said quasi-operation position, so that said cassette may slide down guided by said arm, and which stops said cassette by engaging said arm with said bottom sloping plane of said cassette, when said rear side face of said cassette comes outside said front panel through said cassette insert/eject opening.
