Disclosed is a support structure of a copier cassette reversing feed roller which can significantly extends a lifespan of a reversing feed roller by preventing the reversing feed roller from being rotated in the direction opposite to a transfer direction of paper as an operation structure of the reversing feed roller, mainly used for a copier cassette for Cannon copiers, is improved. According to the present invention, to prevent excessive friction force from being provided to paper due to a problem of the operation structure of the Cannon cassette reversing feed roller, a rotating body, joined to the reversing feed roller, is fixated on a roller shaft regardless of rotation of the roller shaft of a Cannon cassette. Therefore, the lifespan of the reversing feed roller is significantly extended as the reversing feed roller is prevented from providing excessive friction force to paper. Consequently, unnecessary economic loss and inconvenience resulting from replacement of the reversing feed roller can be eliminated. |
