Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
213 words
A magnetic tape recording and/or reproducing apparatus for recording signals on and/or reproducing signals from a magnetic tape wound on reels in a tape cassette, comprising: a capstan (502) for transporting said magnetic tape at a constant speed in cooperation with a pinch roller; a motor (501) for driving said capstan rotatably; cassette loading means (505) for mounting said tape cassette at a predetermined position; tape loading means (508) reciprocating between an inoperative position where said magnetic tape is within said tape cassette and an operative position where said magnetic tape is drawn out of said tape cassette and loaded in a specific tape path; operating mode changing means (506,507) driven by said motor for changing operating mode of said apparatus from one operating mode to another; a pair of reel turntables (513) engageable with said reels for rotating said reels; reel turntable driving means (509) for transmitting a rotational driving force of said motor to said reel turntables; and clutch means (503,504) for transmitting intermittently the rotational driving force of said motor (501) to said cassette loading means (505), said tape loading means (508) and said operating mode changing means (506,507), whereby cassette loading operation, tape loading operation, operating mode changing operation and magnetic tape transporting operation are performed by said motor.
Claim 2
Dependent Claim
213 words
A magnetic tape recording and/or reproducing apparatus for recording signals on and/or reproducing signals from a magnetic tape wound on reels in a tape cassette, comprising: a capstan (502) for transporting said magnetic tape at a constant speed in cooperation with a pinch roller; a motor (501) for driving said capstan rotatably; cassette loading means (505) for mounting said tape cassette at a predetermined position; tape loading means (508) reciprocating between an inoperative position where said magnetic tape is within said tape cassette and an operative position where said magnetic tape is drawn out of said tape cassette and loaded in a specific tape path; operating mode changing means (506,507) driven by said motor for changing operating mode of said apparatus from one operating mode to another; a pair of reel turntables (513) engageable with said reels for rotating said reels; reel turntable driving means (509) for transmitting a rotational driving force of said motor to said reel turntables; and clutch means (503,504) for transmitting intermittently the rotational driving force of said motor (501) to said cassette loading means (505), said tape loading means (508) and said operating mode changing means (506,507), whereby cassette loading operation, tape loading operation, operating mode changing operation and magnetic tape transporting operation are performed by said motor.
Claim 3
Dependent Claim
15 words
Apparatus according to claim 1, wherein said clutch means (503) is driven by an actuator.
Claim 4
Dependent Claim
22 words
Apparatus according to claim 1 or 2, wherein said operating mode changing means (506) works simultaneously with said tape loading means (508).
