Abstract
Abstract A tape auto-loading recording and reproducing apparatus comprises means for drawing tape from the interior of a cassette to the outside, through a tape guide member which enters the loop of the tape thus drawn out. As the guide is about to pass through this loop, it engages the tape and pulls it around. A rotating ring-shaped member provided with this tape guide member is adapted to rotate while surrounding a guide drum and, moreover, with an inclination. The tape drawn out of the cassette is pulled around by the tape guide member together with the rotation of the ring-shaped member and is loaded in a predetermined tape travel path, including a passage wherein the tape is caused to contact the guide drum over a specific range of angle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
298 words
A tape auto-loading recording and reproducing apparatus comprising: a guide drum having associated therewith at least one head mounted to rotate in a given plane; a tape cassette containing a tape and having a casing provided with a side opening extending over a small section on one side of said casing; at least one movable lever means having an associated tape drawing and guiding member which fits through a small opening in the bottom of the tape cassette and adjacent said side opening when said cassette is installed in said apparatus; means for moving said lever means through said side opening and out of said cassette in a manner such that said tape is drawn through said side opening and out of said tape cassette; a ring-shaped guide means surrounding said guide drum and rotatably supported with an inclination relative to said given plane in which said rotating head is mounted, said ring-shaped means and said guide drum being located at a position away from said opening of the tape cassette; at least one tapE guiding member fixed to said ring-shaped guide means and disposed to be spaced apart from the tape to engage the tape drawn out of said tape cassette in response to the rotation of said ring-shaped guide means; rotating means operated responsive to a shift of said lever means for rotating said ring-shaped guide means over a predetermined angle on its plane of inclination whereby said guiding member on said ring-shaped guide means moves from an initial position, engages the tape drawn out of said tape cassette at a second position, and then pulls the tape to wrap around the peripheral surface of said guide drum with an inclination relative to the rotating plane of said rotating head; and means for driving said tape.
Claim 2
Dependent Claim
298 words
A tape auto-loading recording and reproducing apparatus comprising: a guide drum having associated therewith at least one head mounted to rotate in a given plane; a tape cassette containing a tape and having a casing provided with a side opening extending over a small section on one side of said casing; at least one movable lever means having an associated tape drawing and guiding member which fits through a small opening in the bottom of the tape cassette and adjacent said side opening when said cassette is installed in said apparatus; means for moving said lever means through said side opening and out of said cassette in a manner such that said tape is drawn through said side opening and out of said tape cassette; a ring-shaped guide means surrounding said guide drum and rotatably supported with an inclination relative to said given plane in which said rotating head is mounted, said ring-shaped means and said guide drum being located at a position away from said opening of the tape cassette; at least one tapE guiding member fixed to said ring-shaped guide means and disposed to be spaced apart from the tape to engage the tape drawn out of said tape cassette in response to the rotation of said ring-shaped guide means; rotating means operated responsive to a shift of said lever means for rotating said ring-shaped guide means over a predetermined angle on its plane of inclination whereby said guiding member on said ring-shaped guide means moves from an initial position, engages the tape drawn out of said tape cassette at a second position, and then pulls the tape to wrap around the peripheral surface of said guide drum with an inclination relative to the rotating plane of said rotating head; and means for driving said tape.
Claim 3
Dependent Claim
64 words
The tape auto-loading recording and reproducing apparatus as defined in claim 1 wherein said tape driving means comprises a capstan disposed at an inclination with respect to the width of the inclined tape and a pinch roller rotatably mounted on said ring-shaped member for pressing said inclined tape against said capstan in response to the rotation of said ring-shaped member over said predetermined angle.
Claim 4
Dependent Claim
96 words
The tape auto-loading recording and reproducing apparatus as defined in claim 1 wherein said tape cassette contains a supply reel and a take-up reel on which said tape is wound, said supply reel and take-up reel being arranged in a side-by-side relationship, and said movable lever means comprising a single movable lever, said means for moving said single lever drawing a guiding member to move toward the tape take-up reel side whereby the tape extends from the supply reel through the guide drum and then through the tape drawing and guiding member to the take-up reel.
Claim 5
Dependent Claim
68 words
The tape auto-loading recording and reproducing apparatus as defined in claim 1 wherein said movable lever means comprises two movable levers having respective tape drawing and guiding members which are disposed within the tape cassette in their mutually closed positions, said moving means for moving said two movable levers mutually apart to pull the tape out of the tape cassette by the respective tape drawing and guiding members.
Claim 6
Dependent Claim
160 words
The tape auto-loading recording and reproducing apparatus as defined in claim 1 further comprising a guide plate, and wherein said movable lever means comprises a first swinging lever having said tape drawing and guiding member at one end thereof, a second swinging lever pivotally supporting the other end of said first swinging lever on one end thereof, and means for urging said first swingable lever against said guide plate to keep said tape drawing and guiding member within the tape cassette; said lever moving means comprising means for swinging the other end of said second swinging lever in the direction opposite to the urging direction of said urging means whereby, while said second swinging lever swings through a predetermined angle, said tape drawing and guiding member moves along said guide plate to approach the axis of swing of the second swinging lever, and then swings integrally with the second swinging lever with the further swing of the second swinging lever.
Claim 7
Dependent Claim
97 words
The tape auto-loading recording and reproducing apparatus as defined in claim 2 wherein said tape driving means further comprises a lever pivotally supported with play at one end thereof on said ring-shaped member and provided at the other end thereof with said guiding member fixed thereto, said lever further rotatably supporting said pinch roller, and pushing means for urging said lever in such a direction that said pinch roller is pressed against said capstan, whereby when said lever is urged by the pushing means, parallelism of the capstan, the guiding member and the pinch roller is attained.
Claim 8
Dependent Claim
80 words
The tape auto-loading recording and reproducing apparatus as defined in claim 1 wherein said tape cassette contains a supply reel and a take-up reel on which said tape is wound, further comprising means for feeding tape by positively rotating said supply reel in response to a tapE fast-forwarding mode of the apparatus and for positively rotating said take-up reel in response to a tape rewinding mode of the apparatus whereby the reel is positively sent out of the tape cassette.
Claim 9
Dependent Claim
68 words
The tape auto-loading recording and reproducing apparatus as defined in claim 1 wherein said rotating means comprises a driving roller inclined at an angle similar to the inclination of said ring-shaped member, said rotating means pressing against a part of said ring-shaped member, and means for rotating said driving roller in response to the shift of said swinging lever means to said predetermined position by said moving means.
