Guide arrangements for maintaining magnetic tape in proper position
relative to a head
摘要:
A tape guide arrangement for a tape recording and reproducing apparatus comprises a cylinder device provided with a rotary head, a first slant guide member for feeding a tape to the cylinder device, a second slant guide member for guiding the tape from the cylinder device into a predetermined direction, a first rotary guide member for guiding the tape to the first slant guide member, and a second rotary guide member for causing the tape from the second slant guide member to pass through a predetermined position. Each of the first and second rotary guide members is provided with an axis of rotation substantially perpendicular to an imaginary plane defined in relation to positions which are set on the first and second slant guide members and the cylinder device, respectively, and through which an elongated edge of the tape passes. Further, the first rotary guide member is so positioned that the tape is led to the first rotary guide member with a first gradient in reference to the imaginary plane and then guided to the first slant guide member with a second gradient opposite in up and down to the first gradient, and the second rotary guide member is so placed that the tape is guided to the second rotary guide member from the first slant guide member with a third gradient in reference to the imaginary plane and then leaves for the predetermined position with a fourth gradient opposite in up and down to the third gradient.
