PROBLEM TO BE SOLVED: To check insertion of the other recording medium, when either one of two recording media is inserted. SOLUTION: A simultaneous insertion preventive mechanism 24 can install one recording medium inserted first among a first card-like recording medium 26 or a second card-like recording medium 28 and prevents simultaneous installation of two kinds of recoding media by checking insertion of the recording medium inserted later. A first stopper member 30 is displaced in the downward direction in an abutting part 30a by insertion of the first card-like recording medium 26, and a second stopper member 32 rotates backwardly by insertion of the second cad-like recording medium 28. When inserting either one of the first card-like recording medium 26 or the second card-like recording medium 28, the first stopper member 30 and the second stopper member 32 interfere with each other, and operate so as not to insert the other recording medium. |
