Abstract
A roller spacing device roller mechanisms having rollers in close contact under a given pressure to separate first and second rollers by a constant distance to keep the rollers from touching when roller mechanisms are not used for a long period of time. The roller spacing device comprises a spacing member shiftably mounted between first and second positions on a shaft having a partial D-cut portion and associated with one of the roller members to be separated. The spacing member has a spacing nose overlapped in the second position with an outer circumferential surface of a driving gear connected to the other roller member to separate the first roller member from the second roller member by the constant distance; and a shifting unit shifting the spacing member between first and second positions on the shaft. With this construction, the first and second roller members are separated by a constant distance to keep each roller from touching when the roller mechanism is not driven for a long period of time so as to solve several problems which may be generated when the roller members are in contact under a given pressure for a long period of time.
