<p>PURPOSE: To reduce the resistance against the movement between guiding devices by using a flexible belt having a specific shape. CONSTITUTION: The flexible belt 8 at the initial position is positioned on a recessed part 30 in a cassette 29 at the rear side of the tape part, and one side of the belt is clamped with four pins 28 provided on a supporting plate 2 and another side is clamped between two tape putting rollers 12, 13, and a belt putting pin 14 is positioned in a loop of the belt 8. During the tape putting in or drawing out process, the magnetic tape 7 is come to the working state from the initial state and brought into contact with magnetic head means 9, 10 in this working state. The magnetic tape 7 is drawn out from the cassette 29 at this time by two putting rollers 12, 13 and moved to the magnetic head means 9, 10 through there between two pairs of guide rollers 21, 22 and 23, 24, then the magnetic tape 7 is wound round a drum 9 over the angle of 90 deg.. Thus, the resistances against the motion and deformation are small even during the movement between the initial position and the working position.</p> |
