Abstract

There will be provided a wrong insertion prevention device for a cartridge type recording medium capable of reliably preventing a cartridge type recording medium from being inserted into each unit cell in the reverse direction. The invention includes a wrong insertion detector 12 placed side by side with the cell main body 5 for housing a plurality of cartridge type recording media, for detecting wrong insertion of any of the cartridge type recording media 70; and door locking element 13 for operating on the basis of output information from this wrong insertion detector 12 to regulate a closing operation of the door for a housing which has been opened during an insertion operation of the recording medium 70, and the aforesaid wrong insertion detector 12 is configured by: a reverse direction insertion regulating member 5a installed within each cell 5A in the cell main body 5; and an optical sensor mechanism 6 for detecting a portion of the cartridge type recording medium, the insertion operation of which has been inhibited by the regulation of this reverse direction insertion regulating member 5a, and, which, as a result, has protruded outwardly.
