PURPOSE:To exactly clean only a fixed heat by constituting so that a tape makes a reciprocating motion, contacting with only a fixed head within a prescribed range in the longitudinal direction, in a state that the tape has been loaded on a prescribed travelling passage. CONSTITUTION:After loading of a tape 5 has been completed, when the quick-feed button is pushed, the takeup reel 3 is continuously rotation-driven by the takeup reel table 32 in the direction as indicated with an arrow. As a result, the tape reel 4 is intermittently rotation-driven by this takeup reel 3 in the direction as indicated with an arrow, and the tape 5 makes a reciprocating motion intermittenly by the joint operation with the coil spring 10. And, one cleaning part 12 sliding-contacts with both the audio head 26 and the control head 27, cleans dirt of them, and the other cleaning part 13 sliding-contacts with the erasing head 28 and cleans it. In this case, these cleaning parts 12, 13 do not contact at all with the video head drum 25. Accordingly, according to said constitution, only the fixed head can be cleaned exactly. |
