Paper roll supporting device for an image forming apparatus

Abstract

A paper roll supporting device for an image forming apparatus includes a pair of flange members to be inserted into opposite ends of a paper roll. Each flange member includes a flange body made up of a flange portion and a cylindrical support portion that is to be inserted into a tubular core included in the paper roll. A claw member has a plurality of claws capable of protruding from the outer circumference of the support portion. A biasing member exerts a pressure on the claw member. Pressing means is slidable in a direction in which the biasing member is compressible. The pressing means receives one end of the biasing member and contacts the inner circumference of the support portion. A lock/release lever is capable of being brought down for causing the pressing means to slide. The claw member causes its pawls to flare in the radial direction when pressed in the axial direction of the support portion. The device with this configuration can be easily locked to the paper roll.
