Abstract:
1. An image-forming device comprising: a cartridge receiving portion that receives a cartridge detachably mounted therein; a drive engaging unit that can move between an engaged position, in which the drive engaging unit transfers a driving force to the cartridge, and a disengaged position, in which the drive engaging unit fails to transfer a driving force to the cartridge; and a coupling member that moves the drive engaging unit between the engaged position and the disengaged position in association with mounting and detaching of the cartridge in the cartridge receiving portion, wherein the coupling member includes a first contact member that contacts the cartridge when the cartridge is mounted in the cartridge receiving portion, wherein when the cartridge is mounted in the cartridge receiving portion, the first contact member contacts the cartridge, thereby causing the drive engaging unit to move into the engaged position; and wherein when the cartridge is removed, the first contact member is disengaged from the cartridge, thereby causing the drive engaging unit to move into the disengaged position.
