Abstract
A disc drive device includes a disc conveyance mechanism, a slide cam and a trigger slider. The disc conveyance mechanism has a cam driven element protruded on a movement route of the slide cam and a conveyance roller energized in a direction coming into pressure-contact with a disc by an elastic member. The slide cam has a cam contour part moving the conveyance roller in a direction being spaced apart from the disc against an elastic force of the elastic member while pressing the cam driven element. The cam contour part has a flat surface part formed in parallel to a moving direction of the slide cam, in order to move only the trigger slider, while restraining the slide cam by contact pressure of the cam driven element to stop the slide cam temporary, when conveying the disc inside a cabinet toward an aperture side of the cabinet.
