Abstract
A cleaning device for cleaning a rotary magnetic head of a magnetic recording and reproducing device includes a cleaning member which is movable into and out of contact with the rotating magnetic head. The cleaning device is activated through the operation of a manually operable button and under the control of an electronic control device. The cleaning member is automatically brought into contact with the magnetic head to clean the same. The operation of the cleaning device is carried out in association with an operation of a tape loading mechanism of the magnetic recording and reproducing device. The vertical position of the cleaning member is changed when it is contacted with the magnetic head, so that the portion of the cleaning member to be contacted with the magnetic head is changed.
