Abstract
An automatic head cleaning apparatus for a magnetic recording/playback system which has a cleaning roller the vertical position of which is varied so that an area of cleaning member in contact with a head is widened, thereby allowing the useful life of the apparatus to be lengthened. The apparatus comprises an arm pivotably mounted on a pin fixed to base plate which arm is pivoted by being in contact with a moving slant post assembly for causing a tape to be loaded and unloaded on a head drum; an elastic member for biasing the arm in one direction; an operating lever, pivotably mounted on the pin, which is cooperatively connected with the arm; a first member for changing the vertical position of the operating lever in response to a pivoting movement of the operating lever; and a second member for cleaning the head, said second member rotatably mounted on an end of the operating lever which is itself pivoted and moved vertically at the same time, wherein the second member is in contact with the head drum and the head during a tape loading or unloading operation.
