Cassette adapter for playback device, such as a compact disk player

An adapter for enabling the signals produced by a device of the type having a headphone jack to be reproduced as audio sounds by a cassette player audio system of the type having a cassette palyback deck which may be of the front-loading or side-loading type and which includes at least one reel-drive spindle and a playback head, said adapter comprising:

• a housing of a configuration of a cassette normally used with said playback deck, said housing having at least one opening to receive said at least one reel-drive spindle and a peripheral wall having an opening therein;
• a record head supported in said housing in a position for contacting the playback head of said playback deck when said adapter is received in said playback deck;
• audio circuit means within said housing and electrically connected to said record head for providing audio signals to said record head;
• electrical conducting means passing through said opening in said peripheral wall and having one end coupled to said audio circuit means and another end couple to a plug compatible with the headphone jack of said device;
• wherein said peripheral wall has a rear wall section and two side wall sections, and said opening in said peripheral wall comprises a slot located at the corner of said rear wall section and one of said side wall sections and extending partially along each, said slot having radii at both of its ends, each radius having a dimension greater than the width of the slot, such that said electrical conducting means is releasably secured in either radius and passes through the slot free of interference with and merges from said playback deck even if said playback deck is of the front-loading or side-loading type;
• whereby when said adapter is received by said playback deck and said plug is connected to said headphone jack, the signals produced by said device are applied to said record head and applied thereby to said playback head and thence reproduced by said audio system.

• a housing of a configuration of a cassette normally used with said playback deck, said housing having top and bottom walls, first and second openings which extend through said top and bottom walls, first and second reel hubs substantially concentric with said first and second openings, respectively, and interconnecting means for interconnecting said first and second reel hubs such that when said first reel hub is driven by said one reel-drive spindle said second reel hub is driven by said interconnecting means;
• a record head supported in said housing in a position for contacting the playback head of said playback deck when said adapter is received in said playback deck;
• audio circuit means within said housing and electrically connected to said record head for providing audio signals to said record head;
• electrical conducting means passing through said opening in said peripheral wall and having one end coupled to said audio circuit means and another end coupled to a plug compatible with the headphone jack of said device;
• and wherein said opening in said peripheral wall is positioned such that the electrical conducting means which passes through is free of interference with and emerges from said plackback deck even if said playback deck is of the front-loading or side-loading type;
• whereby when said adpater is received by said playback deck and said plug is connected to said headphone jack, the signals produced by said device are applied to said record head and applied thereby to said playback head and thence reproduced by said audio system.

An adapter for enabling the signals produced by a device of the type having a headphone jack to be reproduced as audio sounds by a cassette palyer audio system of the type having a cassette playback deck including at least one reel-drive spindle and a playback head, said adapter comprising a housing of a configuration substantially identical to the configuration of a cassette normally used with said playback deck, said housing having at least one opening to receive said at least one reel-drive spindle and said housing having a rear wall and two side walls, a slot located at the corner of said rear wall and one of said side walls and extending along said rear wall and partially along said one side wall and having a radius at its opposite ends, each said radius having a dimension larger than the width of said slot;

• a record head supported in said housing in a position for contacting the playback head of said playback deck when said adapter is received in said playback deck;
• audio circuit means within said housing and electrically connected to said record head for providing audio signals to said record head;
• and electrical conducting means passing through said slot and releasably secured in either of said radii, said electrical conducting means being coupled at one end thereof to said audio circuit means and at the other end thereof to a plug compatible with the headphone jack of said device;
• whereby when said adapter is received by said playback deck and said plug is connected to said headphone jack, and said device and said playback deck both are operating, the signals produced by said device are applied to said record head from which they are applied to said playback head and thence reproduced by said audio system.
