Abstract
Abstract A recording or reproducing apparatus comprising first means for moving a cassette or a rotary head drum between a position where the cassette and the drum relatively go away from each other and a position where the cassette and the drum relatively come near to each other, detection means for detecting whether or not the cassette is loaded, pulling-out means for pulling out a record bearing medium from the cassette, the pulling-out means being movable between a first position where the pulling-out means is positioned in the cassette and a second position where the pulling-out means has wound the pulled out medium about the rotary head drum by a predetermined angle, and second means responsive to the detection means for moving the pulling-out means from the first position to the second position when the cassette is loaded and for moving the pulling-out means from the first position to a third position which is a middle position between the first position and the second position when the cassette is not loaded.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
202 words
A recording or reproducing apparatus for use with a cassette housing therein a tape shaped record bearing medium, comprising: (A) a rotary head drum assembly having at least one rotary head for recording signals on or reproducing signals from the medium; (B) first means for selectively causing said cassette and said drum assembly to relatively come near to each other and to relatively go away from each other; (C) detection means for detecting whether said cassette is loaded or not; (D) loading means for pulling out the medium from said cassette and for engaging the pulled out medium with said drum assembly, said loading means including at least one movable member which is selectively movable to a first position for pulling out the medium from the cassette, a second position for engaging the pulled out medium with the drum assembly and a third position between said first and said second position; and (E) second means responsive to said detection means for operating said loading means, said second means moving said movable member between said first and said second positions when the cassette is loaded and moving the movable member between said first and said third positions when the cassette is not loaded.
Claim 2
Dependent Claim
202 words
A recording or reproducing apparatus for use with a cassette housing therein a tape shaped record bearing medium, comprising: (A) a rotary head drum assembly having at least one rotary head for recording signals on or reproducing signals from the medium; (B) first means for selectively causing said cassette and said drum assembly to relatively come near to each other and to relatively go away from each other; (C) detection means for detecting whether said cassette is loaded or not; (D) loading means for pulling out the medium from said cassette and for engaging the pulled out medium with said drum assembly, said loading means including at least one movable member which is selectively movable to a first position for pulling out the medium from the cassette, a second position for engaging the pulled out medium with the drum assembly and a third position between said first and said second position; and (E) second means responsive to said detection means for operating said loading means, said second means moving said movable member between said first and said second positions when the cassette is loaded and moving the movable member between said first and said third positions when the cassette is not loaded.
Claim 3
Dependent Claim
44 words
The apparatus according to claim 1, further comprising: means for receiving said cassette; said first means being arranged to selectively cause said cassette receiving means and said drum assembly to relatively come near to each other and to relatively go away from each other.
Claim 4
Dependent Claim
35 words
The apparatus according to claim 2, wherein said drum assembly is fixedly arranged while said receiving means is movable; and said first means is arranged to move said receiving means relative to said drum assembly.
Claim 5
Dependent Claim
19 words
The apparatus according to claim 1, further comprising: control means for sequentially operating said first and said second means.
Claim 6
Dependent Claim
51 words
The apparatus according to claim 4, wherein said control means is arranged to firstly operate said second means to move said movable member from said first to said third positions and then operate said first means to cause said cassette and said drum assembly to relatively come near to each other.
Claim 7
Dependent Claim
48 words
The apparatus according to claim 4, wherein said control means is arranged to firstly operate said first means to cause said cassette and said drum assembly to relatively go away from each other and then operate said second means to move said movable member toward said first position.
Claim 8
Dependent Claim
19 words
The apparatus according to claim 1, further comprising: control means for concurrently operating said first and said second means.
