The present invention provides a communication system and a communication method, whereby a communication status in wireless communications can be arbitrarily designated at the mobile station side, thereby enabling the optimization of communication costs according to the communication status, the structure of the communication system including a mobile station 20 and a base station 30. The method includes the steps of providing an electronic device substrate, mounting an electronic part on the electronic device substrate, removing the tape member and the metal film from the electronic device substrate, and forming a conductive structure at a position corresponding to the metal plating layer. The pick-up gear is rotated when the motor is rotated in a first direction, the feed gear is rotated when the motor is rotated in a second direction, and the discharge gear is rotated constantly in one direction regardless of the rotation direction of the motor. The substrate is configured over a second buffer layer such that the second buffer layer substantially encompasses the whole substrate to decrease damage to the substrate when the side of the substrate is collided with an external object.
