Claims

[Claims for Utility Model Registration] 1. An electrostatic recording device in which a drum unit is configured to be detachable from the main body so that the rotation shaft of the photosensitive drum is connected to or separated from the rotation drive shaft of the main body. The drum unit is attached to an end of the rotational shaft of the drum unit so as to be slidable in the direction of the rotational shaft, and engages with the rotational drive shaft of the main body at a first position and is engaged with the rotational drive shaft of the main body at a second position. a coupling member that is disengaged; a support member that engages a support portion of the body in its first position and disengages in its second position;
and an electrostatic recording device, comprising an operating member that commonly acts on the connecting member and the supporting member to cause positional changes of the connecting member and the supporting member substantially simultaneously. 2. The electrostatic recording device according to claim 1, wherein the operating member includes a lever rotatably supported with respect to the drum unit. 3 The lever is a first lever that acts on the connecting member.
3. The electrostatic recording device according to claim 2, comprising: a lever; and a second lever acting on the support member. 4. The electrostatic recording device according to claim 2 or 3, which is provided with a forcing means for setting the connecting member and the supporting member to the first position when the lever is released. . 5. The electrostatic recording device according to claim 4, wherein the forcing means includes a spring member that deforms when the lever is operated and returns to its original state when the lever is released.
