ABSTRACT:
A cassette-like housing having a cleaning ribbon mounted therein and wound on a pair of spools. The housing is adapted to be positioned in a playing location of a conventional playing/recording unit to operatively engage the video head and other components of the unit to clean the same. There is a cleaning cartridge to clean the capstan and pinch roller of the unit, and this cartridge is adjustable to be moved between two separate locations. In one location, the ribbon is between the capstan and pinch roller, and in the other location, it bypasses the capstan and pinch roller. There is also a mirror device to activate the shut off mechanism.
