PURPOSE:To facilitate a fitting and detaching work to and from a driving shaft part of a drum, and to improve the work efficiency by allowing a door and drum supporting mechanism to be freely movable in the both right and left directions, and also, allowing the front part to be freely openable and closeable, and allowing a photosensitive drum of a body to be tested which is installed in a machine body to be freely fitable and detachable. CONSTITUTION:To a front part 2 of a machine body (a) including a photosensitive drum 1 of a body to be tested, a measuring instrument group, etc. of the drum 1, and a member for supporting and fixing them, a rail 3 which can move a stage 4 installed in a jump-out state to the front part 2 in the both right and left directions is installed, and also, a front part window part is formed. After the measurement is ended, a drum supporting part 19 is detached from the other end part of the drum 1, and when the stage 4, etc. are slid in the right or left direction, the stage 4, etc. move smoothly through the rail 3. Thereafter, a door body 21 installed so as to be freely openable and closeable is opened, and a parameter setting unit 10 is drawn out. In such a way, the work for fitting and inserting, and detaching the drum to and from the shaft part becomes extremely simple, the processing can be executed quickly, and the work efficiency becomes high. |
