Coupling device for radio set and small size tape recorder

Apparatus including a radio and a miniature tape recorder, said radio and tape recorder each being capable of independent operation and operation as an integral unit, said apparatus comprising:

• A. a radio operable in a radio or tape mode, said radio including:
• 1. radio receiver means for converting radio signals into electrical signals;
• 2. a speaker for converting electrical signals into acoustical signals;
• B. a miniature tape recorder operable in a record or playback mode, said tape recorder including:
• 1. magnetic tape head means for converting electrical signals applied thereto into magnetic signals to be applied to a magnetic tape head when said tape recorder is in said record mode and for converting magnetic information stored on a magnetic tape into electrical signals when said tape recorder is in said playback mode;
• 2. a microphone for converting acoustical signals into electrical signals;
• C. coupling means for mechanically and electrically coupling said tape recorder to said radio when said tape recorder and radio are to be operated as a single integrated unit, said coupling device including a pocket formed on one lateral side of said radio and adapted to receive said recorder, said pocket being movable between a first position wherein it is closed and a second position wherein it is open;
• D. switch means responsive to movement of said pocket from said first to said second position, said switch means:
• 1. disabling said microphone and applying said electrical signal generated by said receiver to said tape head when said pocket is in said first position, said radio is in said tape mode and said recorder is in said record mode;
• 2. disabling said microphone and applying said electrical signal generated by said tape head to said speaker when said pocket is in said first position, said radio is in said tape mode and said tape recorder is in said playback mode;
• and
• 3. enabling said microphone and applying said electrical signals generated by said microphone to said tape head when said pocket is in said second position and said tape recorder is in said record mode.
