特定や業務管理等にも役立つと考えられる。However, the conventional nailing machine is not provided with means for knowing the number of times of nailing, and since the state of these built-in parts cannot be visually checked from the outside, it is necessary to replace or maintain parts. It is difficult to predict the arrival. Therefore, the user receives the maintenance service when the deterioration of the performance becomes remarkable, which may cause the work schedule to be delayed during the busy season. Further, if the number of times of nailing can be known, it is considered to be useful for identifying the cause at the time of failure, business management, and the like.
