Claims

[Scope of utility model registration request]

A rotating shaft is rotatably supported on a fixed plate provided on the machine body, and each of the rotating shafts is provided with at least one first lever fixed to the rotating shaft and at least one second lever rotatably attached to the rotating shaft. ,
The first and second levers are provided with engaging members that can engage with each other, and the first and second levers are connected via an elastic body, and the first lever is engaged. A holding mechanism that is removably held is provided at a location other than the second lever in the aircraft body, and when the first lever is engaged and held by the holding mechanism, the second lever is attached to the elastic body. The biasing force applies pressure in a direction transverse to the axial direction of the squeezing roller attached to the machine body, and when the first lever is disengaged from the holding mechanism, the first lever and the second lever are An aperture roller attaching/detaching device for an electronic copying machine, characterized in that the first lever is engaged by an engaging member and rotates freely around the rotation axis without being subjected to the biasing force of the elastic body. .
