像や、音声を正常に記録又は再生できなくなる。Problems to be Solved by the Invention However, in the conventional rotary head cleaning device as shown above, the magnetic tape is in a loading complete state or a state close to this (the state shown by the broken line in FIG. 2).
In order to bring the cleaning member into contact with the rotating head,
Foreign matter (dust, fallen magnetic powder, etc.) attached to the rotating head, scraped powder from the cleaning member, etc. scatters as shown in the figure (arrow A), and some of it attaches to the magnetic tape, causing damage to the image, Audio cannot be recorded or played back properly.

る。The conventional rotary head cleaning device has the above-mentioned drawbacks, and the present invention solves these problems.While cleaning the rotary head, it also eliminates the secondary problem of dropouts. The purpose is to provide a rotary head cleaning device that is inexpensive and highly reliable.
課題を解決するための手段
本発明は、上記目的を達成するため、磁気テープの位置

のである。Means for Solving the Problems In order to achieve the above object, the present invention provides a sensor for detecting the position of the magnetic tape (actually detects the position of the member for loading the magnetic tape), and detects the position specified by the sensor. The cleaning member is configured to come into contact with the rotating head when the magnetic tape is located at a position where the magnetic tape is located.

ーニング部材２を、回転ヘッドに当接させる。The tape position detection sensor 4 detects the position of the magnetic tape 3. As shown by arrow A in the figure, the tape position detection sensor 4 detects scraped powder from the cleaning member 2 and foreign matter (dust) attached to the scraped rotating head. The position is set so that no particles (such as magnetic powder or fallen magnetic powder) will be scattered. When the magnetic tape 3 is at the position defined by the tape position detection sensor 4, the cleaning member 2 is brought into contact with the rotating head.
