Abstract:
1. A magnetic tape guiding device for a transport system of a tape recorder, comprising a pair of pole base assemblies adapted to draw out a magnetic tape and push the magnetic tape to a tight contact with a head drum when a cassette tape is loaded, the magnetic tape guiding device comprising: a tension pole assembly, adapted to apply a tension force to the magnetic tape by pivoting toward an outside edge of a deck of the transport system when the magnetic tape is drawn out; and a supply reel pole base assembly, included in one of the pair of pole base assemblies, and comprising a pole base movably disposed on the deck to be slid when the magnetic tape is drawn out, and a slant pole including a portion angled with respect to the pole base, the slant pole having a central portion with a diameter and a first guide unit to regulate traveling height by contacting an upper edge and a lower edge of the moving magnetic tape, the first guide unit including a sloping guide protrusion disposed at an upper end of the slant pole with an external diameter larger than the diameter of the central portion of the slant pole, the sloping guide protrusion having a lower side that extends at a predetermined sloping angle θ the tension pole assembly comprises a tension arm disposed in the deck to pivot when the magnetic tape is drawn out, and a tension pole extending upright at a front end of the tension arm, the tension pole having a second guide unit to regulate traveling height by contacting the upper edge and the lower edge of the moving magnetic tape, and the magnetic tape travels at a predetermined distance from a surface of the deck as the traveling height is regulated by the tension pole assembly and the pole base assembly.
