Abstract
The utility model discloses an imaging device for verifying imaging cartridge chips. The imaging device comprises a first transmitting/receiving unit, a first storage unit and a first verifying unit. The first storage unit is used to store multiple identification codes for invalidity verification. The first transmitting/receiving unit is used to transmit detection signals to an imaging cartridge chip for the purpose of acquiring an identification code, to receive an identification code transmitted by the imaging cartridge chip and then to transmit the identification code to the first verifying unit. The first verifying unit is used to compare, one by one, the identification code received by the first transmitting/receiving unit with the multiple identification codes for invalidity verification stored in the first storage unit. If identical, then the imaging cartridge chip is verified as invalid. If different, then the imaging cartridge chip is verified as valid.

Below be that sequence number is an example with the identification code, three specific embodiments of tool are elaborated to the utility model.
First embodiment:
Storage sequence look-up table in the imaging device, the illegal sequence number of a plurality of affirmations of storage in this sequence number look-up table.When imaging is box-packed go into imaging device after, the imaging box chip corresponding with the imaging box set up electrical connection.Imaging device sends the detection signal of the sequence number obtain imaging box chip, receives the sequence number of imaging box chip feedback then, and the sequence number of this feedback is to be stored in the image-forming information of storage chip.Imaging device compares the illegal sequence number of a plurality of affirmations in sequence number that receives and the sequence number look-up table one by one, and it is identical whether affirmation has, if, confirm that then this imaging box chip is illegal, refusal uses; If not, confirm that this imaging box chip is legal, adopt the imaging box to carry out follow-up imaging operation.For example; Specific embodiment one sketch map of imaging device checking imaging box chip process as shown in Figure 6; The storage sequence look-up table comprises 11010001 to 11011111 the illegal sequence number of a plurality of affirmations in the imaging device; When the sequence number that receives the imaging box chip feedback is 11010010; Compare one by one, confirm in the sequence number look-up table, to have identical, be exactly this sequence number be duplicate serial numbers; Confirm that then this imaging box chip is illegal, refusal uses; When the sequence number that receives the imaging box chip feedback is 11101010, to compare one by one, affirmation does not have identical in the sequence number look-up table, is exactly that this sequence number is not duplicate serial numbers, confirms that this imaging box chip is legal, uses the imaging box.
Specific embodiment two
Image forming apparatus stores data rule look-up table, the proof rule of storage sequence number.When imaging is box-packed go into imaging device after, the imaging box chip corresponding with the imaging box set up electrical connection.Imaging device sends the detection signal of the sequence number that obtains imaging box chip, receives the sequence number of imaging box chip feedback then, adopts the proof rule of sequence number to verify.For example; The sequence number that receives is divided into two parts; First is a calculating section; Another part is a part as a result, then calculating section is adopted XOR and checking number to carry out computing, if the result that computing obtains is part as a result; Think that then this sequence number repeats; Checking is not passed through, and confirms that this imaging box chip is illegal, and refusal uses; If the result that computing obtains is not part as a result, checking is passed through, and confirms that this imaging box chip is legal, adopts the imaging box to carry out follow-up imaging operation.
As shown in Figure 7; Fig. 7 is specific embodiment two sketch mapes of imaging device checking imaging box chip process; The data rule look-up table of imaging device is the left-half of figure, when receiving sequence number that imaging box chip sends when being 11011110, use the data rule look-up table sequence number proof rule to the first half 1101 of this sequence number one by one with the data rule look-up table in checking number verify calculating; The result finds and 0011 XOR result is 1110; Confirm that then this sequence number is a duplicate serial numbers, confirm that then this imaging box chip is illegal, refusal uses; When the sequence number that receives the imaging box chip transmission is 11101110; After using the proof rule of the sequence number of data rule look-up table that all checkings in the first half 1110 of this sequence number and this data rule look-up table number are carried out XOR; Confirm that this sequence number is not duplicate serial numbers; Confirm that this imaging box chip is legal, use the imaging box.
Again such as, when receiving sequence number that imaging box chip sends when being 11011110, wherein 1101111 is calculating section; 0 is part as a result, and the proof rule of the sequence number of imaging device is even-odd check, then carries out even-odd check to 1101111; Owing to have 61,, confirm that then this sequence number is a duplicate serial numbers so the result is 0; Confirm that then this imaging box chip is illegal, refusal uses.
The 3rd embodiment:
Storage sequence look-up table in the imaging device is stored the sequence number of used all storage chips in this sequence number look-up table.When imaging is box-packed go into imaging device after, the imaging box chip corresponding with the imaging box set up electrical connection.Imaging device sends the detection signal of the sequence number obtain imaging box chip, receives the sequence number of imaging box chip feedback then, and the sequence number of this feedback is to be stored in the image-forming information of storage chip.Imaging device compares the illegal sequence number of a plurality of affirmations in sequence number that receives and the sequence number look-up table one by one, and it is identical whether affirmation has, if, confirm that then this imaging box chip is illegal, refusal uses; If not, confirm that this imaging box chip is legal, adopt the imaging box to carry out follow-up imaging operation.For example; Specific embodiment three sketch mapes of imaging device checking imaging box chip process as shown in Figure 8; During beginning, the sequence number look-up table of imaging device is empty, after the imaging box of first use is installed to imaging device; The sequence number that imaging device receives the corresponding imaging box chip transmission of this imaging box is 10110101, stores; After the imaging box of second use was installed to imaging device, imaging device received the sequence number that the corresponding imaging box chip of this imaging box sends, with stored compare after, find inequalityly, then note; So analogize, after n imaging box that uses was installed to imaging device, n was a natural number; Imaging device receives the sequence number that the corresponding imaging box chip of this imaging box sends, with stored compare after, find inequality; Then note; If identical, think that then this sequence number reuses, refusal uses n the box that forms images.
In the utility model embodiment; Also specific embodiment one can be combined with specific embodiment two; Perhaps specific embodiment one is combined with specific embodiment two; Earlier the sequence number that receives and a plurality of sequence numbers of being stored are compared one by one exactly; If have identical; Confirm that this imaging box chip is illegal, refusal uses; If not, then adopt the proof rule of the sequence number of being stored to verify that if do not pass through, confirm that this imaging box chip is illegal, refusal uses again; If pass through, confirm that this imaging box chip is legal, adopt the imaging box to carry out follow-up imaging operation.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the scope of the utility model protection.
