<p><P>PROBLEM TO BE SOLVED: To provide a system using a magnetic substance for mounting an attachment on a device body, which protects the magnetic substance when handling the attachment and protects the device body. <P>SOLUTION: An attachment 2 is mounted on a device body 1 when being used. The attachment includes a movable magnetic substance 24 that is incorporated in the mounting surface side for the device body 1 so as to be movable in the mounting direction; and a first attraction material 26 that attracts the movable magnetic substance 24 to an opposite side of the mounting surface side. When the attachment 2 is not mounted on the device body 1, the movable magnetic substance 24 is attracted to the opposite side of the mounting surface side by the first attraction material 26, however, when the attachment 2 is mounted on the device body 1, the movable magnetic body 24 is attracted to a second attraction material 14 provided on the mounting surface of the device body 1. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
