Abstract

PURPOSE:To adequately prevent miserasing and misrecording by providing a switch for preventing miserasing and misrecording in a suitable position of the apparatus and letting this be actuated by the presence or not of any object in the sensing part of a magnetic sheet. CONSTITUTION:When a magnetic sheet 5 is placed on a sheet stage 2 and the sheet 5 is held by bringing down a pressure plate 6, a misrecording-miserasing preventing switch 3 is pressed by the sheet 5 and is turned OFF, and recording or reproducing becomes possible. Here, the magnetic sheet desired to be kept is provided with a hole, notch or the like in the sensing part 7 to be put in contact with the switch 3. If this sheet 5 is loaded on the sheet stage 2 of the recorder-reproducer like the above, the switch 3 goes through the sheet 5 and enters the inside of the concave groove 6a formed in the pressure plate 6. In this state the switch 3 goes ON and therefore even if an operation miss is performed, erasing or superposed recording of the sheet 5 may be prevented.
