Abstract
Abstract A magnetic recording and reproducing device of the cartridge loading type utilizing for its operation a movement of the magnetic tape magazine in which a magnetic tape is wound on a reel at the time the cartridge is inserted in and removed from the device. Specifically, a video tape recorder adapted to be mounted with a tape magazine has a mechanism for drawing the tape out of the tape magazine and for bringing the tape into contact with a tape guide provided with a rotary magnetic head or with a stationary magnetic head in response to the movement of the tape magazine when it is inserted in the magnetic tape recorder, a mechanism for removing the magnetic tape from the tape guide, stationary magnetic head or the like and returning it into the magazine in response to the movement of the tape magazine when it is removed from the recorder, a mechanism for bringing the tape out of contact with the tape guide, stationary magnetic head or the like for reducing the friction exerted on the running tape when the tape is fast forwarded or rewound, and a mechanism for making it easy to insert the tape cartridge in and remove it from the tape recorder.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
181 words
In a magnetic recording and reproducing device comprising a tape guide including a rotary magnetic head therein, a tape magazine including a magnetic tape wound on a pair of reels mounted therein, and a pair of movable posts for moving said tape out of said tape magazine toward a pair of position control members disposed in the vicinity of said tape guide, the improvement which comprises means for moving said movable posts to bring said magnetic tape into contact with the periphery of said tape guide in response to the insertion movement of said tape magazine through an interlocking mechanical means, said means for moving said movable posts, including a toothed wheel provided on a plate moving together with said tape magazine in engagement therewith, and means for transmitting a driving force from said toothed wheel, wherein said movable posts are engaged with said means for transmitting a driving force, whereby said magnetic tape is brought into contact with the periphery of said tape guide by moving said movable posts by a longer distance than that said tape magazine is moved.
Claim 2
Dependent Claim
181 words
In a magnetic recording and reproducing device comprising a tape guide including a rotary magnetic head therein, a tape magazine including a magnetic tape wound on a pair of reels mounted therein, and a pair of movable posts for moving said tape out of said tape magazine toward a pair of position control members disposed in the vicinity of said tape guide, the improvement which comprises means for moving said movable posts to bring said magnetic tape into contact with the periphery of said tape guide in response to the insertion movement of said tape magazine through an interlocking mechanical means, said means for moving said movable posts, including a toothed wheel provided on a plate moving together with said tape magazine in engagement therewith, and means for transmitting a driving force from said toothed wheel, wherein said movable posts are engaged with said means for transmitting a driving force, whereby said magnetic tape is brought into contact with the periphery of said tape guide by moving said movable posts by a longer distance than that said tape magazine is moved.
Claim 3
Dependent Claim
212 words
In a magnetic recording and reproducing device comprising a tape guide including a rotary magnetic head therein, a tape magazine including a magnetic tape wound on a pair of reels mounted therein, and a pair of movable posts for moving said tape out of said tape magazine toward a pair of position control members disposed in the vicinity of said tape guide, the improvement which comprises means for moving said movable posts to bring said magnetic tape into contact with the periphery of said tape guide in response to the insertion movement of said tape magazine through an interlocking mechanical means, wherein said tape magazine including a magnetic tape wound on a pair of reels therein is provided with an opening at the side walls thereof, a pair of rotatable members are provided in said tape magazine with a part thereof exposed therefrom through said openings, said reels being made to rotate with the rotation of said rotatable members, and a side plate is provided at the position where the exposed part of said rotatable member is brought into frictional contact therewith when said tape magazine is unloaded from said device, whereby the loosened magnetic tape is wound back onto the reel in response to the unloading operation of the tape magazine.
Claim 4
Dependent Claim
212 words
In a magnetic recording and reproducing device comprising a tape guide including a rotary magnetic head therein, a tape magazine including a magnetic tape wound on a pair of reels mounted therein, and a pair of movable posts for moving said tape out of said tape magazine toward a pair of position control members disposed in the vicinity of said tape guide, the improvement which comprises means for moving said movable posts to bring said magnetic tape into contact with the periphery of said tape guide in response to the insertion movement of said tape magazine through an interlocking mechanical means, wherein said tape magazine including a magnetic tape wound on a pair of reels therein is provided with an opening at the side walls thereof, a pair of rotatable members are provided in said tape magazine with a part thereof exposed therefrom through said openings, said reels being made to rotate with the rotation of said rotatable members, and a side plate is provided at the position where the exposed part of said rotatable member is brought into frictional contact therewith when said tape magazine is unloaded from said device, whereby the loosened magnetic tape is wound back onto the reel in response to the unloading operation of the tape magazine.
