Therefore, if a part of the sliding contact surface of the cleaning member 32 gets dirty due to sliding contact with the cleaning tape C, the take-up roll 36 (feeding roll 34) rotates a predetermined amount in one direction, so that a new sliding surface of the cleaning member 32 is obtained. The cleaning tape C can be cleaned on the contact surface.

The cleaning member 32 is made of a nonwoven fabric or the like. Further, the take-up roll 36 is wound up with the sliding contact (contact) surface side of the cleaning member 32 with the cleaning tape C facing inward. Thereby, the dirty slidable contact surface of the cleaning member 32 is not exposed, and dust or the like can be prevented from falling from the slidable contact surface.

Also, the replacement timing of the sliding contact surface of the cleaning member 32 is determined from the number of cleanings, for example, replacement after cleaning the entire length of the cleaning tape C once. The timing for bringing the cleaning member 32 into sliding contact with the cleaning tape C is determined by detecting the amount of reel 10 fed (the amount of reel 20 taken up).

Further, as shown in FIGS. 1 and 2, the traveling path P of the cleaning tape C is sandwiched between the pressing roll 42 and one guide roll 38 and between the pressing roll 42 and the other guide roll 38. On the opposite side, a pair of support rolls 46 that support the cleaning tape C against which the cleaning member 32 is pressed in a stretched state are provided so as to be freely rotatable at a predetermined interval.

Thereby, the cleaning tape C can be slidably contacted with the cleaning member 32. That is, the cleaning member 32 can clean the cleaning tape C over its entire length.

Then, the feeding amount of the reel 10 (the winding amount of the reel 20) is controlled (detected), and the end portion of the cleaning tape C in the feeding direction is disposed opposite to the cleaning member 32. Next, the pressing roll 42 waiting at the retracted position is moved in the pressing direction A by the moving means.

At this time, since the cleaning tape C is supported in a stretched state by the pair of support rolls 46, the pressing member 42 moves in the pressure contact direction A of the cleaning member 32 stretched between the pair of guide rolls 38. By doing so, it is pressed against the cleaning tape C (see FIG. 4). When the cleaning member 32 is pressed against the cleaning tape C, the reels 10 and 20 are rotated by a predetermined amount (an amount capable of cleaning the entire length of the cleaning tape C), and the cleaning tape C is brought into sliding contact with the cleaning member 32 relatively.

Thereby, the cleaning tape C is satisfactorily cleaned over its entire length, and the recording / reproducing head 70 is cleaned again by the cleaned cleaning tape C. When cleaning of the cleaning tape C by the cleaning member 32 is completed, the pressing roll 42 is moved in the separation direction B by the moving means, and the cleaning member 32 is retracted from the recording tape T traveling along the traveling path P.

Further, when the cleaning of the cleaning tape C by the cleaning member 32 is completed, the winding roll 36 (feeding roll 34) is moved in one direction (the direction in which the cleaning member 32 is wound) in a state where the pressing roll 42 is retracted to the retracted position. The sliding contact surface of the cleaning member 32 that is rotated and is brought into sliding contact with the cleaning tape C is replaced.

Thereby, it is possible to prepare for the next cleaning operation for the cleaning tape C. Further, since the cleaning tape C can be cleaned until the cleaning member 32 wound around the feeding roll 34 is used up, the cleaning tape C can be cleaned over a long period of time.
