Abstract
In order to make it possible to determine the erroneous insertion of an information recording medium at a position close to a recording medium insertion port by utilizing a notch portion provided at the information recording medium, the present invention relates to an electronic apparatus comprising a recording medium insertion port for taking in and out a memory stick having a notch portion used to prevent erroneous insertion and provided in one corner, and an erroneous insertion preventive mechanism provided inside the recording medium insertion port so as to prevent the erroneous insertion of the memory stick, and recording and/or reproducing an information signal using the memory stick. The erroneous insertion preventive mechanism is moved outside for the notch portion of the memory stick to allow the insertion of the memory stick, and is engaged for corners other than the notch portion to hamper the insertion of the memory stick.
