Filed: 1994-07-11
Abstract: PURPOSE:To reduce the height of a head drum to a required minimum by a method wherein a twist angle in a path between an inclined guide post for a magnetic tape and a guide roller is made large. CONSTITUTION:A twist angle in a path between inclined guide posts 19, 20 for a magnetic tape 12 and guide rollers 21, 22 is set to be larger than an inclined angle in a direction perpendicular to a mechanical chassis 16 for the shaft of a drum 17. Then, when a loading operation is completed, the upper edge of the head drum 17 does not bump against the inside of the front lid of a tape cassette 1. When the twist angle is made large, it is not required to make the inclination angle of the head drum 17 larger than required. As a result, a large wrap angle can be set without making the inclination angle of the head drum 17 large, and the magnetic tape 12 can be wound in large quantities. Consequently, the height of the head drum 17 can be reduced to a required minimum, and the tape cassette 1 can be mounted in a state that a part of the head drum 17 is positioned at the inside of the front lid 3 installed at the tape cassette.
