Claims

[Scope of utility model registration request]

A loading mechanism used for loading a cartridge with a shutter that accommodates a disk-shaped recording medium into a reading and/or writing device and positioning it at a predetermined operating position, which can now accommodate a cartridge with a shutter. a housing; a shutter release lever pivotally mounted within the housing to engage and release the shutter member when the cartridge with a shutter is inserted into the housing; The disc is movable up and down between an upper position accommodating a cartridge and an operating position below this upper position, and when the housing is lowered to the operating position, the disk in the cartridge with a shutter is housed in the housing. In a loading mechanism in which a shaped recording medium is accessed by a read head, an abutment member that comes into contact with the shutter member when the housing is lowered to the operating position is adjacent to the read head. A loading mechanism characterized by being arranged.
