Structure preventing the use of an unauthorized circuit board
View Patent ↗A toner cartridge prevents piggybacking of an unauthorized circuit board over an authorized circuit board. The body of the cartridge includes a flat mounting surface adapted to receive a first circuit board formed in a vertical wall of the waste bin. An upper blocking member extends from a point just above the flat mounting surface to a lower surface of the planar wing. An optional lower blocking member extends from a point just below the flat mounting surface to a preselected point at a still further lower elevation. The upper and lower blocking members obstruct the placing of an unauthorized circuit board over an authorized circuit board.
1. A toner cartridge adapted to fit within a toner cartridge-receiving cavity of a printer, comprising:
a waste bin;
a flat mounting surface adapted to receive a first circuit board; and
a blocking structure that prevents placement of a replacement circuit board into overlying relation to said first circuit board.
2. The toner cartridge of claim 1 wherein the flat mounting surface is formed in a vertical wall of said waste bin.
3. The toner cartridge of claim 1 wherein the blocking structure comprises an upper blocking member extending from a point just above said flat mounting surface to a preselected point at a higher elevation;
whereby said upper blocking member obstructs the placing of a replacement circuit board over said first circuit board.
4. The toner cartridge of claim 1 wherein the blocking structure comprises a lower blocking member extending from a point just below said flat mounting surface to a preselected point at a lower elevation;
whereby said lower blocking member obstructs the placing of a replacement circuit board over said first circuit board.
5. The toner cartridge of claim 1 wherein said flat mounting surface comprises:
an elevated surface adapted to receive a first circuit board; and
a recessed surface adapted to receive a second circuit board having a size that is smaller than said first circuit board.
6. The toner cartridge of claim 5 wherein said structure prevents placement of a replacement circuit board into overlying relation to said second circuit board.
7. The toner cartridge of claim 1 wherein the flat mounting surface has an upper extent terminating at a point substantially related to the first circuit board; whereby no physical structure extends vertically from the flat mounting surface to which a circuit board can be mounted.
8. A toner cartridge adapted to fit within a toner cartridge-receiving cavity of a printer, comprising:
a waste bin;
a planar wing formed in a sidewall of said waste bin;
the planar wing formed on an outboard side of its associated sidewall;
a flat mounting surface adapted to receive a first circuit board formed in a wall of said waste bin; and
an upper blocking member that prevents placement of a replacement circuit board into overlying relation to said first circuit board.
9. The toner cartridge of claim 8 wherein said flat mounting surface comprises:
an elevated surface adapted to receive a first circuit board; and
a recessed surface adapted to receive a second circuit board having a size that is smaller than said first circuit board.
10. The toner cartridge of claim 9 wherein said upper blocking member prevents placement of a replacement circuit board into overlying relation to said second circuit board.
11. The toner cartridge of claim 8 wherein said upper blocking member extends from a point just above said flat mounting surface to a lower surface of said planar wing and whereby said upper blocking member obstructs the placing of a second circuit board over said first circuit board.
12. The toner cartridge of claim 8 further comprising a lower blocking member that prevents the placement of a replacement circuit board into overlying relation to said first circuit board.
13. The toner cartridge of claim 12 wherein said lower blocking member extends from a point just below said flat mounting surface to a preselected point at a lower elevation and whereby said lower arcuate blocking member obstructs the placing of a replacement circuit board over said first circuit board.
14. The toner cartridge of claim 8 wherein the flat mounting surface is formed in a vertical wall of said waste bin.
15. The toner cartridge of claim 8 wherein the flat mounting surface has an upper extent terminating at a point substantially related to the first circuit board; whereby no physical structure extends vertically from the flat mounting surface to which a circuit board can be mounted.
16. A toner cartridge adapted to fit within a toner cartridge-receiving cavity of a printer, comprising:
a waste bin;
a flat mounting surface formed in a vertical wall of said waste bin, said flat mounting surface further comprising;
said flat mounting surface having an upper extent terminating at a point substantially related to the first circuit board; and
whereby no physical structure extends vertically from the flat mounting surface to which a circuit board can be mounted;
a planar wing formed in a sidewall of said waste bin;
the planar wing formed on an outboard side of its associated sidewall;
an upper blocking member extending from a point just above said flat mounting surface to a lower surface of said planar wing; and
whereby said upper blocking member obstructs the placing of a replacement circuit board over said first circuit board.
