<p>PURPOSE:To prevent a tape from being run onto a rotary head drum by shutting a gap between a cover body and the circumference surface of the rotary head drum with a tape shutter, which is turned in the vertical direction when the cover body of a tape cassette is opened. CONSTITUTION:The tip of a tape shutter 27 contacts a circumference surface 4a of a rotary head drum 4 and completely shuts a gap A between a cover body 8 and the circumference surface 4a of the rotary head drum 4 when the cover body 8 is opened. Accordingly, for example, even when looseness is generated in a tape 9 between front opening parts 7a and 7b of a tape cassette 7 to be opened by the opening of the cover body 8 and this tape 9 tends to jump out on the rotary head drum 4 simultaneously with the slight opening of the cover body 8, the tape shutter 27 goes to be a wall and the tape 9 is not run onto the rotary head drum 4. Then, the tape 9 is securely guided between the circumference surface 4a of the rotary head drum 4 and the cassette 7 by the tape shutter 27. Thus, the tape 9 can be prevented from being loaded on the rotary head drum 4.</p> |
