Patent ID: 8353475

Claim:
A roll recording material transport device comprising: a pair of roll holders attached to respective ends of a roll portion of a roll of recording material; a pair of spindles that engage with the pair of roll holders and support the roll portion; a spindle driving source that rotates one of the pair of spindles on the driving side in the forward direction and the reverse direction; a driving side support mechanism and a driven side support mechanism that support one of the pair of spindles on the driving side and the other on the driven side, respectively; a transport roller that pinches and transports the roll of recording material pulled out from the roll portion; and an assist executing section that executes assist control in which a rotating force in the direction of transporting the roll of recording material is applied by the spindle driving source through the driving side spindle and the driving side roll holder in an engaged state to the roll portion, wherein when the rotation of the roll portion is at a stop, the driving side spindle, driven by the spindle driving source, overcomes the frictional force with the driving side roll holder and rotates relative to the driving side roll holder and goes into an engaged state in which the rotating force for the assist control is applied to the roll portion, wherein the driving side support mechanism and the driven side support mechanism include support frames, and wherein the support frame on the driven side includes a friction applying member that generates the frictional force of the driven side spindle.
