<P>PROBLEM TO BE SOLVED: To provide an apparatus misidentification preventing tablet that allows proper operation of apparatuses without causing a human error, and to provide an apparatus misidentification preventing unit. <P>SOLUTION: An apparatus misidentification preventing tablet includes a combination of: attachment bases 1 and 2 having a plurality of pins 1a and 2a projecting therefrom; and a set of two operation cards 10 and 20 having respective hooking holes 10a and 20a which are arranged line-symmetrically and through which the pins 1a and 2a penetrate. The operation cards 10 and 20 are overlaid and attached to the attachment bases 1 and 2, with the front surfaces or the rear surfaces thereof facing each other. On one end side of the operation card 10, a magnet 11 is provided that exerts a magnetic force on a contact point 33a that is opened and closed by the magnetic force. On the other end side of the operation card 20, a magnet 21 is provided that exerts a magnetic force on another contact point 33b that is opened and closed by the magnetic force. An apparatus misidentification preventing unit includes a combination of the apparatus misidentification preventing tablet and a switch having the two contact points 33a and 33b at each of which a movable part 31 is brought into and out of contact with a fixed part 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
