Official abstract text for this publication.
A power transmission device includes a drive coupling, a driven coupling, and an intermediate transmission member. The drive coupling receives power from a drive source and rotates. The driven coupling is disposed coaxially on a first rotary shaft of the drive coupling and detachably attachable relative to the main body of the image forming apparatus. The intermediate transmission member meshes with the drive coupling and the driven coupling and is held by one of the drive coupling and the driven coupling in a state in which the driven coupling is disengaged from the main body. One of the drive coupling and the driven coupling, whichever holds the intermediate transmission member, constitutes a retaining coupling including an attachment member attached to one of a drive-side device and a driven-side device, and a stopper assembly facing the intermediate transmission member in an axial direction of the first rotary shaft.
Opening claim text (preview).
What is claimed is: 1. A power transmission device, comprising: a drive coupling to receive power from a drive source of a main body of an image forming apparatus and rotate; a driven coupling disposed coaxially on a first rotary shaft of the drive coupling and detachably attachable relative to the main body of the image forming apparatus; and an intermediate transmission member, including at least a first flange, to mesh with the drive coupling and the driven coupling, the in…
