Abstract RU 2715590 C2

FIELD: physics.

SUBSTANCE: invention relates to an adapter forming device. Adapter device includes the first fastening element on one side and the second fastening element on the other side. First fastening element is detachably mounted on the image forming device, and the second fastening element is detachably mounted on the accessory. First fastening element has recesses of fastening element from first to third and ledges of fastening element from first to third, located in circular direction. Second fastening element has recesses of attachment element from fourth to sixth and ledges of fastening element from fourth to sixth, located in circular direction. Recesses of the fastening element from the first to the third are the insertion elements inserted into recesses on the other image forming device. Recesses of the fastening element from the fourth to the sixth are the insertion elements inserted into recesses on the other accessory. Smallest range of angles from ranges of angles in the circular direction of the recesses of the fastening element from the first to the third is less than or equal to the smallest range of angles from the ranges of angles in the circular direction of the recesses of the fastening element from the fourth to the sixth.

EFFECT: technical result consists in reduction of deformation and wear of contact pins provided on chamber housing.
