Claims

[Claims for Utility Model Registration] 1. A device comprising a support structure and a process unit detachably attached to the support structure, the process unit being attached to a unit frame and the unit frame and having a photoreceptor on its surface. In the image generating machine including a movable photoconductor support means, a protective cover member is further attached to the unit frame so as to be movable in directions approaching and away from the movable photoconductor support means, and the protective cover member is movable in directions toward and away from the movable photoconductor support means. In the state where it is separated from the support structure,
The protective cover member is held in a protective position spaced apart from the movable photoreceptor support means, while when the process unit is removably mounted on the support structure and ready for copying, the protective cover member An image generator, characterized in that the image generator is placed in an exposure position close to a movable photoreceptor support means. 2. The unit frame is attached to the support structure so as to be freely movable in the front-rear direction, and is detached from the support structure by moving the unit frame forward in the front-rear direction, while the unit frame is moved forward in the front-rear direction. The image generating machine according to claim 1, which is positioned in a working position where copying is possible by moving the machine backward. 3. The support structure is provided with a cam means capable of acting on the protective cover member, and when the process unit is mounted on the support structure and moved rearward in the front-rear direction to bring it into the action position. The image generating machine according to claim 2, wherein the protective cover member is brought to the exposed position by the action of the cam means. 4. The support structure includes a lower support frame and an upper support frame mounted on the lower support frame so as to be pivotable between an open position and a closed position, and the process unit is mounted on the upper support frame. The image generating machine according to claim 2, which is detachably mounted. 5. The lower support frame is provided with exposed position positioning means that can act on the protective cover member, and when the process unit is attached to the upper support frame, the upper support frame is moved to the open position. When the upper support frame is placed in the closed position, the protective cover member is placed in the protected position, and when the upper support frame is placed in the closed position, the protective cover member is placed in the exposed position positioning means. , Utility Model Registration Claim No. 4, which is placed in the exposed position.
The image generator described in Section 1. 6. The exposed position positioning means is composed of a positioning projection provided on the lower support frame, and when the upper support frame is placed in the closed position with the process unit attached to the upper support frame,
The image generating machine according to claim 5, wherein the positioning projection acts on the protective cover member to bring it to the exposed position. 7 Utility model registration claims 1 to 6, wherein the unit frame is provided with a biasing means for biasing the protective cover member toward the protected position.
The image generator according to any of the above.
