Device for eliminating curl of recording paper for use in image forming apparatus

A curl eliminating unit for a printing unit, the printing unit having a main body case, a paper tray mounted in the main body case for holding roll paper, means for feeding paper from the roll paper along a paper feed path, and a pivotal cover pivotably mounted to the main body case for providing access to at least the roll paper, the curl eliminating unit comprising:

• a holding member pivotally mounted at each side of said main body case;
• a support roller mounted between said holding members in a manner that permits movement away from and toward the paper tray over which paper being removed from the roll paper passes;
• a curl eliminating plate extending from the pivotal cover and having a nose portion for engaging the paper downstream of said support roller as the paper moves along the paper feed path;
• and
• a restricting member mounted to said curl eliminating plate, said restricting member engaging and restraining said support roller when the pivotal cover is closed.

• a projecting guide portion downstream, on a paper feed path, of the paper tray;
• a holding member pivotally mounted at each side of said main body case, said holding member downstream of said projecting guide portion;
• a support roller mounted between said holding members in a manner that permits movement away from and toward said projecting guide portion and over which paper being removed from the roll paper passes;
• a curl eliminating plate extending from the pivotal cover and having a nose portion for engaging the paper downstream of said support roller as the paper moves along the paper feed path;
• a restricting member mounted to said curl eliminating plate, said restricting member engaging and restraining said support roller when the pivotal cover is closed;
• an expansible coil spring associated with each said holding member for causing pivotal movement of said holding members;
• and
• a stopper at each side of the main body case for engaging said support roller and stopping further pivotal movement by said holding members.
