(2) Furthermore, in the case of the second invention, a ring-shaped protrusion is formed on the inner surface of the parameter setting unit facing each other, the parameter stage is rotatably mounted between both protrusions, and a stage is provided on these stages. Since the measuring equipment group (corotron, probe, etc.) was attached and the rail was attached to the lower part of the setting unit, the setting unit etc. on the rail paralleled the left and right wall surfaces constituting the aircraft, By expanding the front side wall surface portion that constitutes it, the measuring instrument group mounted on the setting unit can be pulled out at the same time as the setting unit and the like, and by such pulling out, the setting position of the measuring instrument group can be freely set. Adjust,
It also has the advantage that measurement parameters can be changed freely.

1. A photosensitive drum fixed in a quadrangular shape when viewed from the upper side so as to be in parallel with the left and right wall surfaces of the surrounding wall surface which constitutes the measuring machine body, and is horizontally removably fixed. In a photosensitive drum testing device having a measuring device group attached to the outer periphery of the front wall surface portion having a window portion formed at a predetermined position in the surrounding wall surface portion constituting the machine body, while being mounted so as to be deployable outward , The rails for movement mounted on the surface of the front side wall are connected to the door / drum support mechanism that is movable toward both the left and right side wall parts that form the surrounding wall part of the machine and that can open and close the window part. When the front side wall surface portion is opened, the door / drum support mechanism is simultaneously opened, and on the contrary, the front side wall surface portion is shielded, so that the other end portion of the built-in photosensitive drum is supported by the drum support member which constitutes the door / drum support mechanism. Through the department The photosensitive drum testing device is characterized in that

2. A photosensitive drum fixed in a horizontal body in a quadrilateral shape when viewed from the upper side so as to be parallel to the left and right wall surfaces of the surrounding wall surface constituting the measuring body and in a horizontal state. In the photosensitive drum testing device with the measuring equipment group attached to the outer circumference of the, the rails were laid inside the machine in parallel with the front and rear side wall surfaces, and the drum was set in a direction perpendicular to the drive shaft part driven by the motor to allow the drum to move in and out freely. The setting units having the fitting and inserting parts are made to face each other and are established with a predetermined interval, and ring-shaped projections are attached to the inner side surfaces of the facing setting units along the fitting and inserting parts and fixed to both projections. A plurality of parameter stages can be attached via a tool, and the corotron and probe can be attached to the base part attached to the parameter stage, and the lower part of the setting unit cannot be removed and can be moved relative to the rail. The photosensitive drum testing apparatus is characterized in that after the front side wall surface portion is unfolded, the setting unit is pulled out to the front surface portion of the machine body so that the photosensitive drum of the DUT can be freely inserted and removed.
