Abstract
To provide a 'disk device' that does not waste a power during waiting for disk insertion and thus can save power consumption. The disk device includes: a casing equipped with an insertion port to which a disk is inserted; a conveying mechanism for conveying a disk, which is provided inside the insertion port; a switching type detecting switch that is switched to a detection state in accordance with a movement force of a disk inserted from the insertion port in an insertion direction; and an optical detecting member that is switched to a detection state when a disk inserted from the insertion port blocks an optical path, wherein when the detecting switch is switched to a detection state, power supply to the optical detecting member is started.
