Claims
- 1. A pole base assembly for a magnetic recording/reproducing apparatus for guiding a tape drawn from a reel through a predetermined path toward a lead surface of a head drum, the pole base assembly comprising:
a pole base disposed to approach and retreat from a side of the head drum when the tape is loaded and unloaded, respectively; a sloping pole, coupled to the pole base and sloped at a sloping angle with respect to the pole base, for guiding the tape fed to the head drum at a predetermined angle, to be substantially parallel to the lead surface; and a supporting holder, disposed on the pole base and configured to support the sloping pole at the sloping angle.
- 2. A pole base assembly as claimed in claim 1, wherein the supporting holder comprises:
a first supporting wall that has a sloping surface for supporting the sloping pole at the sloping angle.
- 3. A pole base assembly as claimed in claim 1, wherein the supporting holder comprises a second supporting wall that has a supporting surface in contact with the supporting wall for supporting the sloping pole.
- 4. A pole base assembly as claimed in claim 2, wherein:
the first supporting wall has a gradually increasing thickness from an upper end to a lower end.
- 5. A pole base assembly as claimed in claim 2, wherein:
the sloping surface has a width that is greater than the radius of the sloping pole and smaller than the diameter of the sloping pole.
- 6. A pole base assembly as claimed in claim 2, wherein:
the sloping surface has a width that is substantially uniform along the length of the sloping surface.
- 7. A pole base assembly as claimed in claim 3, wherein:
the supporting surface is formed at substantially 90° with respect to the sloping surface.
- 8. A pole base assembly as claimed in claim 3, wherein:
the supporting surface has a width that is greater than the radius of the sloping pole and smaller than the diameter of the sloping pole.
- 9. A pole base assembly as claimed in claim 3, wherein:
the supporting surface has a substantially uniform width.
- 10. A pole base assembly as claimed in claim 3, wherein:
the second supporting wall has a sub-sloping surface which is in substantially parallel relation with respect to the sloping surface.
- 11. A pole base assembly as claimed in claim 2, wherein:
the supporting holder includes a bottom surface which is adapted to contact and support a lower end of the sloping pole, and extends at substantially 90° with respect to the sloping surface.
- 12. A pole base assembly as claimed in claim 1, wherein:
the pole base has a supporting hole therein and a supporting boss spaced from the supporting hole, such that a first axis X extends from the center of the supporting hole to the center of the supporting boss, a second axis Y extends in line with the center of the supporting hole, and a third axis Z extends in a perpendicular relation with respect to the first axis X and the second axis Y.
- 13. A pole base assembly as claimed in claim 12, wherein:
the sloping pole is located at a direction angle θ with respect to the first axis X.
- 14. A pole base assembly as claimed in claim 12, wherein:
the sloping pole is disposed on the pole base to have a predetermined slope α with respect to another imaginary axis Y′ which is in parallel with the second axis Y.
- 15. A pole base assembly as claimed in claim 1, wherein:
the sloping pole is bonded to the pole base with adhesive.
- 16. A pole base assembly as claimed in claim 1, wherein:
the sloping pole is formed integral with the pole base.
