发明名称 Recording apparatus and a drive switching method using a partially untoothed gear for use with said recording apparatus
摘要 A recording apparatus comprises a first gear, a second gear meshable with the first gear, a third gear meshable with the first gear and the second gear. The third gear has a peripheral surface on which a toothed portion meshable with the first gear and an untoothed portion not meshable with a toothed portion of the first gear are disposed opposable to the first gear, and a peripheral surface on which a toothed portion meshable with the second gear is disposed opposable to said second gear, a gear drive switching control unit controls switching such that when the toothed portion adjacent the untoothed portion of the third gear comes into contact with the first gear, the second gear and the third gear are meshed to rotate the third gear to oppose the untoothed portion of the third gear to the first gear, thereby releasing the contact between the first gear and the third gear.
