Abstract
Abstract A recording and/or reproducing apparatus with a capstan rotatably journalled in two bearings, at least one of the two bearings being movable by an adjusting device so as to adjust the angular position of the capstan. The apparatus has a straight-line guide, along which the adjustable bearing is movable; and the adjusting device is constituted by a movable control slide which has a sliding surface which moves the bearing along the guide when the control slide is moved.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
A recording and/or playback apparatus for a record carrier in the form of a tape, comprising a drive shaft rotatable about a longitudinal direction for transport of a tape; two bearings spaced apart from each other in the longitudinal direction of the shaft, in which the shaft is rotatably journalled; and means for mounting the bearings arranged to permit pivoting of the shaft longitudinal direction and for adjusting the angular position of the shaft relative to a reference surface, said means including an adjusting device for moving at least one of the bearings, wherein the apparatus includes a guide along which said at least one bearing is movable in a direction of guiding, and said device comprises a movable control slide having at least one sliding surface arranged at an acute angle with respect to said direction of guiding, said slide moving said at least one bearing along the guide as the slide is moved.
Claim 2
Dependent Claim
155 words
A recording and/or playback apparatus for a record carrier in the form of a tape, comprising a drive shaft rotatable about a longitudinal direction for transport of a tape; two bearings spaced apart from each other in the longitudinal direction of the shaft, in which the shaft is rotatably journalled; and means for mounting the bearings arranged to permit pivoting of the shaft longitudinal direction and for adjusting the angular position of the shaft relative to a reference surface, said means including an adjusting device for moving at least one of the bearings, wherein the apparatus includes a guide along which said at least one bearing is movable in a direction of guiding, and said device comprises a movable control slide having at least one sliding surface arranged at an acute angle with respect to said direction of guiding, said slide moving said at least one bearing along the guide as the slide is moved.
Claim 3
Dependent Claim
41 words
An apparatus as claimed in claim 1, wherein said guide is a straight-line guide, said at least one bearing being movable in a straight line parallel to the direction of record carrier movement as it is transported toward the drive shaft.
Claim 4
Dependent Claim
54 words
An apparatus as claimed in claim 1, wherein said guide is a slotted hole having straight parallel side walls; said sliding surface is a side wall of a slotted hole having straight parallel side walls; and said movable bearing has a cylindrical portion extending through said holes for sliding engagement with said side walls.
Claim 5
Dependent Claim
17 words
An apparatus as claimed in claim 1, 2 or 3 wherein said acute angle is approximately 85°.
Claim 6
Dependent Claim
28 words
