Abstract

A head drum cleaning device for a magnetic recording and reproducing apparatus comprising a head cleaning lever pivotally mounted to a fixed base plate of the apparatus by a pin fixed to the fixed base plate, a cleaning roller rotatably mounted to one end of the head cleaning lever by a pin fixed to the head cleaning lever, a drive member constituted by a part of a slide base of the apparatus and adapted to drive the head cleaning lever, and a head cleaning lever rotating unit operatively connected to the drive member and adapted to pivot the head cleaning lever through two steps, namely, in toward the drum and then in the reverse direction. The head drum cleaning device has a simple construction capable of achieving a smooth cleaning operation, in that the head cleaning lever is actuated by the drive member mounted to the slide base to clean the rotating head drum. The head drum cleaning device can be applied to compact camcorders such as 8 mm camcorders using the slide base.
