PURPOSE:To display the color of a developing unit with simple constitution by mounting the developing unit in a copying machine and viewing a label displaying the development color of the developing unit with the eye through an observation window. CONSTITUTION:At the time of the developing unit 3 is mounted in the copying machine, a plate type arm 6 is fallen down horizontally around a hinge at its lower end and set at a specific position of the copying machine, and a copying machine casing 1 is closed. Then, the observation window 2 comes to the position where the color label 4 on the display surface atop of the arm 6 is covered. The arm 6 of the unit 3 taken out of the copying machine is folded, locked by a lock part 6a, and stored. Thus, the color of the developer in the unit 3 is viewed clearly with the simple constitution. |
