Abstract
Abstract In a tape guide arrangement for a tape recording and reproducing apparatus comprising a cylinder device (11) provided with a rotary head (13, 14) and a tape position control member (12); a first slant guide member (15) for feeding a tape (T) to the cylinder device (11) to cause the tape to pass said cylinder device with one elongated edge thereof (Te) in contact with the tape position control member (12); a second slant guide member (16) for guiding the tape which has passed said cylinder device to a predetermined direction; a first rotary guide member (21) for guiding the tape to said first slant guide member (15); and a second rotary guide member (22) for causing the tape which has passed through said second slant guide (16) member to pass through a predetermined position;… an improvement wherein each of said first rotary guide member (21), said first slant guide member (15), said cylinder device (11) and said tape position control member (12), said second slant guide member (16) and said second rotary guide member (22) respectively define a portion of a predetermined path for said tape through said apparatus so that said first rotary guide member (21) guides the tape (T) arriving thereat with a first gradient ((-)1) relative to an imaginary plane (Q) to said first slant guide member (15) along a path with a second gradient ((-)2) opposite in direction to said first gradient, and said second rotary guide member (23) causes the tape (T) arriving thereat from said second slant guide member (16) with a third gradient ((-)3) relative to said imaginary plane (Q) to exit therefrom with a fourth gradient ((-)4) opposite in an up and down direction to said third gradient ((-)3).

Claim 1
Independent Claim
299 words
In a tape guide arrangement for a tape recording and reproducing apparatus comprising a cylinder device (11) provided with a rotary head (13, 14) and a tape position control member (12); a first slant guide member (15) for feeding a tape (T) to the cylinder device (11) to cause the tape to pass said cylinder device with one elongated edge thereof (Te) in contact with the tape position control member (12); a second slant guide member (16) for guiding the tape which has passed said cylinder device to a predetermined direction; a first rotary guide member (21) for guiding the tape to said first slant guide member (15); and a second rotary guide member (22) for causing the tape which has passed through said second slant guide (16) member to pass through a predetermined position; an improvement wherein each of said first rotary guide member (21), said first slant guide member (15), said cylinder device (11) and said tape position control member (12), said second slant guide member (16) and said second rotary guide member (22) respectively define a portion of a predetermined path for said tape through said apparatus so that said first rotary guide member (21) guides the tape (T) arriving thereat with a first gradient (6 1 ) relative to an imaginary plane (Q) to said first slant guide member (15) along a path with a second gradient (6 2 ) opposite in direction to said first gradient, and said second rotary guide member (23) causes the tape (T) arriving thereat from said second slant guide member (16) with a third gradient (8 3 ) relative to said imaginary plane (Q) to exit therefrom with a fourth gradient (8 4 ) opposite in an up and down direction to said third gradient ( 8 3 ).
Claim 2
Dependent Claim
299 words
In a tape guide arrangement for a tape recording and reproducing apparatus comprising a cylinder device (11) provided with a rotary head (13, 14) and a tape position control member (12); a first slant guide member (15) for feeding a tape (T) to the cylinder device (11) to cause the tape to pass said cylinder device with one elongated edge thereof (Te) in contact with the tape position control member (12); a second slant guide member (16) for guiding the tape which has passed said cylinder device to a predetermined direction; a first rotary guide member (21) for guiding the tape to said first slant guide member (15); and a second rotary guide member (22) for causing the tape which has passed through said second slant guide (16) member to pass through a predetermined position; an improvement wherein each of said first rotary guide member (21), said first slant guide member (15), said cylinder device (11) and said tape position control member (12), said second slant guide member (16) and said second rotary guide member (22) respectively define a portion of a predetermined path for said tape through said apparatus so that said first rotary guide member (21) guides the tape (T) arriving thereat with a first gradient (6 1 ) relative to an imaginary plane (Q) to said first slant guide member (15) along a path with a second gradient (6 2 ) opposite in direction to said first gradient, and said second rotary guide member (23) causes the tape (T) arriving thereat from said second slant guide member (16) with a third gradient (8 3 ) relative to said imaginary plane (Q) to exit therefrom with a fourth gradient (8 4 ) opposite in an up and down direction to said third gradient ( 8 3 ).
Claim 3
Dependent Claim
