摘要： The present invention relates to a tape simulator of a cassette tape type digital audio/video device built in the cassette tape type digital audio/video device and capable of normally operating a cassette deck player by having the tape simulator recognized as a cassette tape as reproducing voice/video digital signals recorded in the device in use of the cassette deck player. The tape simulator of the cassette tape type digital audio/video device according to the present invention comprises left and right reel hubs inserted in both driving reels of the cassette deck player to be rotated; and a rotation speed attenuating unit for attenuating the rotation speeds of the left and right reel hubs to at a predetermined rate by providing resistance to the left and right reel hubs rotated by the driving reels. The rotation speed attenuating unit includes a center gear simultaneously meshed with the left and right reel hubs; a torque producing unit for applying a certain torque to the center gear, or an idle gear meshed with the left and right reel hubs to run idle; and a rubber roller being in rolling contact with the pinch roller of the cassette deck player and meshed with the idle gear. With the structure, overall problems can be solved due to the use of a belt since the use of the belt is excluded.
