Total Claims: 4
Claim 1
Independent Claim
217 words
An information recording and/or reproducing system for use with tape-shaped recording media respectively housed in a first cassette and a second cassette, said second cassette being larger than the first cassette in size, said system comprising in combination: (1) an information recording and/or reproducing apparatus comprising: (A) a first chamber for accommodating the first cassette; (B) recording and/or reproducing means for recording information on and/or reproducing recorded information from the recording medium; and (C) first movable means movable from first to second positions for extracting the recording medium from the first cassette and for moving same into a position adjacent the recording and/or reproducing means to allow transducing of signals to or from the medium; and (2) an adapter comprising: (D) a second chamber for accommodating the second cassette; (E) a third chamber adapted to be substantially insertable in said first chamber of said apparatus wherein said third chamber is in physical communication with said second chamber of said adapter; (F) second movable means movable from third to fourth positions for extracting the recording medium from the second cassette and for placing the medium at a predetermined position within said third chamber to relay the medium from the second cassette to said first movable means in the apparatus at said first position of the first movable means.
Claim 2
Dependent Claim

An information recording and/or reproducing system for use with tape-shaped recording media respectively housed in a first cassette and a second cassette, said second cassette being larger than the first cassette in size, said system comprising in combination: (1) an information recording and/or reproducing apparatus comprising: (A) a first chamber for accommodating the first cassette; (B) recording and/or reproducing means for recording information on and/or reproducing recorded information from the recording medium; and (C) first movable means movable from first to second positions for extracting the recording medium from the first cassette and for moving same into a position adjacent the recording and/or reproducing means to allow transducing of signals to or from the medium; and (2) an adapter comprising: (D) a second chamber for accommodating the second cassette; (E) a third chamber adapted to be substantially insertable in said first chamber of said apparatus wherein said third chamber is in physical communication with said second chamber of said adapter; (F) second movable means movable from third to fourth positions for extracting the recording medium from the second cassette and for placing the medium at a predetermined position within said third chamber to relay the medium from the second cassette to said first movable means in the apparatus at said first position of the first movable means.
Claim 3
Dependent Claim
213 words
An information recording and/or reproducing system for use with tape-shaped recording media respectively housed in a first cassette and a second cassette which is larger in size than the first cassette, said system comprising: (1) an information recording and/or reproducing apparatus comprising: (A) means forming a first chamber for accommodating the first cassette; (B) recording and/or reproducing means for recording information on and/or reproducing recorded information from the recording medium; (C) first movable means movable from first to second positions for extracting the recording medium from the first cassette and for moving the medium into a position relative to the recording and/or reproducing means to allow transducing of signals to or from the medium; and (2) an adapter comprising: (D) means forming a second chamber for accommodating the second cassette; (E) means forming a third chamber engageable with said first chamber of said apparatus and in physical communication with said second chamber of said adapter; and (F) second movable means movable from third to fourth position for extracting the recording medium from the second cassette and for pacing the medium at a predetermined position within said third chamber to relay the medium from the second cassette to said first movable means in the apparatus at said first position of the first movable means.
Claim 4
