Abstract
Abstract A radio - cassette tape recorder/player system in which mode selection is accomplished with a single-touch operation. Function switches are provided corresponding to OFF or STOP, cassette tape recording/playing, AM radio reception, and FM radio reception. The OFF function switch operates to halt operations for both the cassette tape recording/playing mode and the AM and FM radio reception modes. An electronic control circuit operates a cassette operating mechanism and the radio receiving circuits in response to momentary actuation of the function switches.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
142 words
A radio-cassette tape recorder/player system, comprising; a plurality of switches for effecting at least a cassette tape recording function, a cassette tape playing function, an AM reception function and an FM reception function, respectively; an electrical logic circuit coupled to said switches for controlling the function of said system in response to the switch selected; at least an AM tuner, an FM tuner and a cassette operating mechanism, each being controlled by said electrical logic circuit; said electrical logic circuit including means for controlling said cassette operating mechanism such that at least said cassette tape playing function is directly achieved upon the actuation of only a corresponding one of said switches, regardless of the then effected one of said functions, whereby at least cassette playing may be achieved through the operation of a single switch when switching from others of said functions.
Claim 2
Dependent Claim
142 words
A radio-cassette tape recorder/player system, comprising; a plurality of switches for effecting at least a cassette tape recording function, a cassette tape playing function, an AM reception function and an FM reception function, respectively; an electrical logic circuit coupled to said switches for controlling the function of said system in response to the switch selected; at least an AM tuner, an FM tuner and a cassette operating mechanism, each being controlled by said electrical logic circuit; said electrical logic circuit including means for controlling said cassette operating mechanism such that at least said cassette tape playing function is directly achieved upon the actuation of only a corresponding one of said switches, regardless of the then effected one of said functions, whereby at least cassette playing may be achieved through the operation of a single switch when switching from others of said functions.
Claim 3
Dependent Claim
57 words
A system as claimed in claim 1, wherein said electrical logic circuit includes flip-flop means, and said plurality of switches further includes a stop switch for effecting a cassette tape STOP function, said flip-flop means operating to prevent said cassette operation mechanism from initiating said cassette tape recording function unless said stop switch has been previously actuated.
Claim 4
Dependent Claim
44 words
A system as claimed in claim 2, wherein said electrical logic circuit includes means enabling switching from others of said functions directly to one of said AM reception function or FM reception function, in response to the actuation of a single corresponding switch therefor.
Claim 5
Dependent Claim
53 words
A system as claimed in claim 3, wherein said electrical logic circuit includes means for controlling said cassette operating mechanism so as to direct the latter to achieve said cassette tape STOP function when one of cassette tape playing and cassette tape recording comprises the function effected prior to said switching of functions.
Claim 6
Dependent Claim
45 words
The radio-cassette tape recorder/player system of claim 2, further comprising switch means coupled to said electrical logic circuit for sensing an inter-song interval, and wherein said electrical logic circuit comprises means for operating said cassette operating mechanism in response thereto to perform a song-repeat operation.
Claim 7
Dependent Claim
50 words
The radio-cassette tape recorder/player system of claim 1, said electrical logic circuit comprising storing means operating in response to said cassette tape recording, said cassette tape playing AM radio reception, and FM radio reception function switches for storing a digital bit in response to momentary actuation of said function switches.
Claim 8
Dependent Claim
44 words
The radio-cassette tape recorder/player system of claim 6, further comprising a plurality of tape mode function switches including a fast-forward switch and a rewind switch, each of said fast-forward switch and said rewind switch being coupled to a corresponding input of said storing means.
Claim 9
Dependent Claim
56 words
The radio-cassette tape recorder/player system of claim 6, further comprising switch means coupled to said electrical logic circuit for sensing an end of a cassette tape being played, said electrical logic circuit operating to set said cassette operating mechanism in a stopped state in response to said switch sensing said end of said cassette being played.
