A screen film applicator includes a seat, a positioning member, and a first mechanism, the latter two of which are disposed on the seat. The seat has a track and a positioning portion arranged beside the track. The positioning member is movable with respect to the positioning portion for clamping a communication device. The first mechanism includes a top fixing member disposed on the seat, a moving carriage movable along the track, a bottom fixing member synchronously movable with the moving carriage, and a roller movable with the moving carriage. The top and the bottom fixing members are configured to respectively fix a top releasing film and a bottom releasing film respectively adhered on two opposite sides of a soft screen film. When the moving carriage is moved away from the top fixing member, the roller can gradually press the soft screen film onto the communication device.

An apparatus for attaching a protective film to a film attachment target includes a protective film guide around which a protective film is wound in a roll form; a protective film unwinding roller configured to unwind the protective film from the protective film guide; a vacuum suction guide configured to vacuum-suction one end of the unwound protective film, and to transfer the vacuum-suctioned one end of the protective film to a corresponding end of an area of the film attachment target; a pressing means configured to: press and attach the vacuum-suctioned end of the protective film to the corresponding end of the area of the film attachment target; and then press and attach the protective film to a remaining area of the film attachment target while moving and pressing an area of the protective film overlapping the remaining area; and a cutter for cutting the protective film.
