Abstract
A roller support apparatus includes a compression coil spring, lever, bias canceling member, roller holder, and support. The compression coil spring biases the distribution roller in a direction to come close to the oscillating roller. The lever transmits a biasing force of the compression coil spring to the distribution roller. The bias canceling member cancels bias of the compression coil spring. The roller holder rotatable supports the distribution roller and pivots in accordance with movement of the lever. The support is provided to the roller holder and engages with a shaft portion of the distribution roller. The support brings the outer surface of the distribution roller into contact with the outer surface of the oscillating roller in accordance with pivot motion of the roller holder.
Claims18
A roller support apparatus with which an outer surface of a first roller and an outer surface of a second roller come into contact with and separate from each other by radially moving said first roller, comprising:
- a biasing member which biases said first roller in a direction to come close to said second roller;
- a lever which transmits a biasing force of said biasing member to said first roller;
- bias canceling means for canceling bias of said biasing member;
- a roller holder which rotatably supports said first roller and pivots in accordance with movement of said lever;
- an axial support which is provided to said roller holder and which engages with a shaft portion of said first roller, said axial support serving to bring the outer surface of said first roller into contact with the outer surface of said second roller in accordance with pivot motion of said roller holder;
- and
- an inner frame which is arranged inside a frame and supports said first roller, wherein said lever, biasing member, and bias canceling means are disposed between said frame and inner frame.
