DEVELOPING BOX

摘要

A developing box, comprising chips (35, 35', 45, 75, 850) which are arranged on the developing box, and conductive connecting pieces (34, 34', 44, 64, 64', 74). A chip contact head (13) is arranged on a cover (11) of a printer; one end of each of the conductive connecting pieces (34, 34', 44, 64, 64', 74) is connected to chip terminals (351, 351', 451, 751); and when the developing box is inserted into the printer and the cover (11) is closed, the other end of each of the conductive connecting pieces (34, 34', 44, 64, 64', 74) squeezes the developing box while coming into contact with a side surface of the chip contact head (13) on the cover (11), so that the developing box cannot vibrate up and down in the using process.
