ABSTRACT:
A shutter opening device for opening a shutter of a cartridge when the cartridge is loaded into an information processing apparatus such as a magneto-optical recording/reproducing apparatus has an engagement mechanism which is adapted to engage with a portion of the shutter when the cartridge is inserted. The engagement mechanism causes the shutter to be in an open state during the course of loading of the cartridge. The engagement mechanism is movable with the cartridge in the loading operation while the open state of the shutter is maintained until the completion of the loading to avoid any interference of the shutter with a magnetic field application device.
