Abstract
A recording and/or reproducing apparatus has a guide drum including at least one rotating head. A tape guide guides a recording tape helically, relative to the rotating plane of the head, around the cylindrical surface of the guide drum. A mechanism is provided for adjusting the tape guide position. The mechanism comprises a member for supporting the tape guide, and means for causing the supporting member together with the tape guide. The height position and the uniformity of tension in the transverse direction of the tape or in the vicinity of the guide drum are adjusted by displacement of the tape guide.
Claims7
In a recording and/or reproducing apparatus having a horizontal base plate, a guide drum including at least one head mounted to rotate in a plane within said drum, the cylindrical surface of said drum being inclined with respect to said base plate, recording tape disposed about a tape supply reel, the guide drum and a tape take-up reel in such a way that said tape defines a portion of a cylinder about said guide drum and the longitudinal center of said tape is disposed on substantially a single horizontal plane, and tape guide means for guiding the tape along a predetermined tape path, said tape guide means including a pair of height position guide means disposed respectively on the tape inlet side and on the tape outlet side of the cylindrical surface of said guide drum, a pair of guide poles disposed respectively between said height position guide means and said guide drum, each of said height position guide means having a pair of flanges for guiding the edges of said tape, each of said guide poles being inclined with respect to said base plate to convert between rectilinear and helical movements of said tape, the improvement in said tape guide means comprising:
- first means for supporting one of said height position guide means;
- first displacing means for causing the first support means and the supported height position guide means to be displaced horizontally and to change the distance between the guide drum and said one of the height position guide means, to thereby adjust the height position of the tape on the guide drum;
- first locking means for locking the first support means after the adjustment of said first displacing means;
- a second means for supporting one of said guide poles between the guide drum and said one of the height position guide means;
- second displacing means for causing the second supporting means and the supported guide pole to be rotatably displaced horizontally and to change the inclination of the pole with respect to the axis of said guide drum, to thereby adjust the uniformity of tape tension across the width of the tape on and in the vicinity of the guide drum;
- and
- second locking means for locking the second supporting means after the adjustment of said second displacing means.
