  The problems of the conventional method of assembling the lock pedestal are as follows. That is, (a) First, since the number of parts constituting the read / write device is large, the pedestal in which the read / write device is built becomes thick in appearance. In addition, the general consumer is given the impression that the thickness balance of the appearance of the vertically long pedestal for the lock is poor. (B) Second, since a plurality of fixing tools are used, it is not easy to set the substrate on the base. In particular, if the read / write device is divided into, for example, a perforated antenna substrate and a device main body substrate on which electronic components are mounted, from the viewpoint of the efficiency of component manufacture and the ease of component replacement, the number of components to be configured As a result, the mounting time for the pedestal increases. (C) Generally, since the antenna of the antenna substrate constituting the read / write device uses an antenna coil in which a conductive material is spirally wound, when a plurality of attachment holes are formed at both ends of the antenna substrate, There are restrictions on the external dimensions and design of the antenna substrate.
