Consumable cartridge and printer

Abstract

The application provides a consumable box and a printer. The consumable box has a paper bin. The consumable box comprises a box body and a pressing assembly. The box body protrudes with a mounting column in the paper bin. A label paper roll is sleeved on the mounting column. A paper guide wall is formed in the box body. The distance between the rotating disc and the inner bottom wall of the paper bin is greater than the height of the label paper roll, so that the rotating disc is spaced apart from the label paper roll. Therefore, the rotating disc cannot interfere with the label paper roll. Thus, the label paper roll cannot be spread under the driving of the rotating disc, thereby ensuring the normal paper feeding of the label paper. The driving member can drive the rotating disc to rotate around the axis of the mounting column, so that the pressing member is in the first position of pressing the label paper against the paper guide wall and in the second position of relaxing the label paper. In the second position, the channel width of the paper feeding channel is greater than the thickness of the label paper. Thus, the label paper cannot contact the pressing member when feeding, thereby reducing the friction and ensuring the smoothness of the label paper feeding.
