The CATV tap assembly of the present invention comprises a tap faceplate and associated components for forming an integrated F-Type connector. The heating elements cause thermochromic media to selectively darken in accordance with selective activation of the heating elements as the media moves in relation to the thermal printhead, to print a desired image on the media. A cavity is formed between the blade and the structure body and also between the seal fin and the partition wall which faces thereto in the rotating shaft direction of the structure body on the upstream side. In one preferred embodiment of the present invention, the steering mechanism includes a rear portion which is nested between two end portions of the front portion and the front portion and the rear portion form a tulip shape.
