1. A cartridge comprising:
- a detection gear rotatable about an axis extending in a predetermined direction, the detection gear including a protrusion movable with rotation of the detection gear; and
a memory including a storage region configured to store new product determination information representing that the cartridge is detected as a new product in response to motion of the protrusion and a determination that the new product determination information is not stored in the storage region.

Abstract
A cartridge includes a detection gear and a memory. The detection gear may be rotatable about a first axis extending in a predetermined direction. The detection gear may include a first protrusion movable with rotation of the detection gear. The memory may include a first storage region configured to store, based on the motion of the first protrusion, new product determination information representing that the cartridge is detected as a new product.

14. An image forming apparatus comprising:
a cartridge including; a detection gear rotatable about an axis extending in a predetermined direction, the detection gear including a protrusion movable with rotation of the detection gear; a memory including a storage region; a frame configured to hold the cartridge; a sensor configured to detect the motion of the protrusion; and a controller configured to; determine whether a detection signal which is detected by the sensor is a new product waveform representing that the cartridge is a new product in response to motion of the protrusion, and write, in the storage region, new product determination information representing that the cartridge is detected as a new product, when the controller determines that the detection signal is the new product waveform. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23)
