PROBLEM TO BE SOLVED: To properly operate information processing to an electronic medium by preventing the positional deviation of a body to be detected which is set so as to be freely movable in a casing. SOLUTION: The electronic medium is provided with a casing 4 incorporating an electronic part so as to be inserted into an information processor, a slide switch 5 formed so as to be freely movable between first and second positions P1 and P2 of this casing 4 detecting whether the moving position of the slide switch 5 is the first position P1 or the second position P2 where this casing 4 is inserted into the information processor, and for inhibiting the writing of any information in an electronic part according to the detected position, and a projecting part 3b for positioning and holding the slide switch 5 when the slide switch 5 is moved to the first or second position P1 or P2. |
