ム装着装置。[Claims for Utility Model Registration] A tapered shaft protruding from the axis of an original image drum of an image scanning recording device is fitted into a tapered hole formed in a rotating main shaft of the device main body, and a root portion of the tapered shaft is provided. The bayonet chuck is tightened by engaging a bayonet pawl formed in the shape with a bayonet chuck attached to the tip of the rotating main shaft and rotating an annular nut screwed onto the outer periphery of the rotating main shaft. In the apparatus, the original drum is fixedly held on the rotating main shaft by means of a contact shaft, which is provided upright at a proper position opposite to the bayonet chuck of the annular nut, and the annular nut of the bayonet chuck is fixed to the rotation main shaft. a stopper projecting so as to limit excessive rotation by abutting the abutment shaft when the abutment shaft rotates to a fixed position; and an annular nut on the opposite side of the abutment shaft to the abutment shaft When rotating to the fixed position,
An original image drum mounting device for an image scanning and recording apparatus, comprising a locking clip stop means for allowing the abutment shaft to pass therethrough and holding the abutment shaft between the stopper and the stopper.
