Abstract
An arrangement for moving a developer material along the developer axis where a bulk of the developer material is stored in a reservoir located on one side of the developer. The developer consists of the reservoir and a housing having a cavity extending along the developer axis. Several angled ribs are formed inside the cavity. A magnetically transparent sleeve resides inside the cavity and is rotated about the axis. Finally a magnetic element placed inside the sleeve magnetically attracts the developer material toward the sleeve such that the rotation of the sleeve induces the rotation in the developer material. As the developer material comes into contact with the angled ribs, the rotation of the developer material is translated into a lateral motion along the axis by the angled ribs.
Claims9
An arrangement for moving a material along an axis, said arrangement comprising of:
- a. a housing having a cavity, said cavity extending along said axis;
- b. a plurality of angled members formed inside said cavity;
- and
- c. a rotation means mounted inside said housing, said rotation means induces said material to rotate about said axis, said material being in contact with said plurality of angled members, wherein said rotation of said material is translated into a lateral motion of said material along said axis by said plurality of angled members.
A developer used in an output means, said developer comprising of:
- a developer housing;
- a developer material inside said developer housing, said developer material having magnetic properties;
- a developer material supply located on a first side of said developer housing;
- a developer sleeve, said developer sleeve being hollow and formed from magnetically transparent material, said developer sleeve being placed inside said developer housing, said developer sleeve further being rotated about an axis;
- a magnetic element placed inside said developer sleeve, said magnetic element magnetically attracts said developer material toward said developer sleeve such that said rotation of said developer sleeve induces a rotational motion about said axis in said developer material;
- and
- said developer housing having angled ribs formed inside, said angled ribs arranged wherein said rotational motion of said developer material is translated into a lateral motion of said developer material in a direction away from said first side of said developer housing.
A developer used in an output means, said developer comprising of:
- a developer housing;
- a developer material inside said developer housing, said developer material having magnetic properties;
- a developer material supply located on a first side of said developer;
- a developer sleeve, said developer sleeve being hollow and formed from magnetically transparent material, said developer sleeve being placed inside said developer housing;
- a magnetic element placed inside said developer sleeve, said magnetic element further being rotated about an axis, said magnetic element magnetically attracts said developer material toward said developer sleeve, said rotation of said magnetic element induces a rotational motion about said axis in said developer material;
- and
- said developer housing having angled ribs formed inside, said angled ribs arranged wherein said rotational motion of said developer material is translated into a lateral motion of said developer material in a direction away from said first side of said developer housing.
