PURPOSE:To prevent the wrong insertion of a pack into a magazine by forming a detecting surface which is matched with the direction control surface of the pack, on the opening/closing cover of an opening part for drawing out a magnetic sheet pack. CONSTITUTION:A detecting surface 36 for preventing a tapered wrong insertion is formed in the inside of a rear cover 34 provided so as to be freely rotatable on the upper end of a magazine body, and this detecting surface 36 corresponds to the tapered surface 24 of a magnetic sheet pack 10. Accordingly, when the detecting surface 36 of the magazine side and the tapered surface 24 of the pack 10 are matched with each other, the pack 10 is contained in the magazine body and the front cover 32 of the front of the magazine is closed completely. On the other hand, in case when the pack 10 is inserted in a wrong direction and the tapered surface 24 and the detecting surface 36 are not matched with each other, the pack 10 is not inserted completely, a part is projected from the magazine, and the front cover 32 is not closed completely. In this way, the wrong insertion of the sheet 10 is detected by whether the front cover 32 has been closed completely or not, and the wrong insertion can be prevented.
