Abstract
Abstract A structure improvement of cleaner tape cartridge for video tape recorder/player which is characterized by providing a blockader to the protective cover of said cartridge, when the said cartridge is disposed in the camera or the adapter with larger VHS tape, the blockader can blockade the ultraviolet ray emitted from the interior of said camera or adapter so as to prevent the ultraviolet ray from penetrating the cleaner tape and being received by the receiver and to prevent the cleaner tape from generating wrong rewinding action in favor of smoothly proceeding with the operation of cleaning the magnetic head which is really a simple improved structure capable of developing great effect.
