Abstract

SE TRATA DE UN APARATO DE TENSION DE LA CINTA DE LA UNIDAD REBOBINADORA DEL CASETE DE LAS CINTAS MAGNETICAS EN SU CAVIDAD, PARA EVITAR QUE EL ANCO CAMBIE EN LA DIRECCION QUE GIRA LA CINTA, QUE SUELE CAUSAR UNA VARIACION DE TENSION, LA CUAL SE ORIGINA EN EL VACIO DE LA CAMARA, Y EL CAMBIO DE POSICION DE LA POSICION DE LA CINTA MAGNETICA RESULTA DAÑADA DENTRO DEL CASETE, LA CUAL SE DETECTA COMO EL CAMBIO DE PRESION CAUSADO LA AVERIA POR DONDE PASA EL AIRE A LA CINTA VIA DE LA CAVIDAD, DONDE APARENTEMENTE SU MEDIDA CAMBIA CUANDO LA CINTA RUEDA. POR CONSIGUIENTE, CON ESTE APARATO PUEDE SER MODIFICADO, DE MANERA QUE RESULTE OPTIMO SU FUNCIONAMIENTO.
