Description
Technical field
The present invention relates to technical field of imaging, be specifically related to a kind of developer container amount detection unit and imaging device that is used for imaging device.
Background technology
Application number discloses a kind of developing apparatus for the Chinese invention patent Shen Qing Publication instructions of " 200810131782.7 ", as shown in Figure 1, this developing apparatus comprises: possess peristome and take in developer developer container 3, be positioned at the peristome of developer container and be used for the developing parts 1 of bearing developer and be positioned at developer container and be used to supply with the supply part 2 of developer, and a kind of detecting unit that is used to detect the developer capacity is specifically disclosed.As shown in Figure 2, this detecting unit comprises above-mentioned developing parts 1 and supply part 2, in detecting unit, this supply part 2 is used for as the detection part 2 that detects the developer capacity, this detecting unit also comprises detecting device 29 that is connected with developing parts 1 and the voltage source 30 that is connected with detection part 2, wherein, voltage source 30 is used for applying bias voltage to detection part 2, and detecting device 29 is used to detect the electrical signal of reaction on the developing parts 1.Concrete, this developing apparatus can be a printer, and developing parts 1 can be a developer roll 1, and detection part 2 (being supply part) can be a powder feeding roller 2, and developer can be a carbon dust, developer container 3 can be a cartridge 3.
Detecting unit detects the developer capacity to carry out after stopping developing operation, at first, voltage source 30 applies one to powder feeding roller 2 and detects bias voltage, for example 50Hz, 200V, at this moment, on developer roll 1, will produce an induced voltage, after detecting device 29 detects this induced voltage, this induced voltage and pre-set threshold voltage are compared, can draw the capacity of carbon dust in the cartridge 3.
The principle that this detecting unit detects the developer capacity is as follows: can form a coupling capacitance between powder feeding roller and the developer roll, the carbon dust that holds in the size of this coupling capacitance and the powder feeding roller how much relevant.Because of this coupling capacitance, when powder feeding roller is applied in a bias voltage, this ac signal can be sent to and promptly on developer roll, produces an induced voltage on the developer roll, the size of this induced voltage is relevant with the size of coupling capacitance.Concrete: the carbon dust that in powder feeding roller, holds more for a long time, the capacitance between developer roll and the powder feeding roller is also bigger, to the coupling effect of ac signal might as well, the ac signal intensity that transmits between powder feeding roller and the developing roller is also big; Carbon dust in powder feeding roller after a little while, the capacitance between developer roll and the powder feeding roller also reduces, and is also poor to the coupling effect of ac signal, the ac signal intensity that transmits between powder feeding roller and the developing roller also a little less than.And how many what of carbon dust amount in the powder feeding roller are linear relevant with carbon dust amount in the cartridge.Therefore, the detecting unit of printer just can utilize detecting device by detecting the power of the ac signal that transmits between powder feeding roller and the developing roller, also is the size of induced voltage on the developer roll, judges the interior carbon dust capacity of cartridge of printer.
As shown in Figure 3, when machine on the cartridge is promptly packed printer first into, the detecting unit of printer can detect the power of the ac signal that transmits between powder feeding roller and the developing roller, whether the size that also is induced voltage on the developer roll meets the demands, if the coupling capacitance between developer roll and the powder feeding roller is lower than certain setting value (10PF for example, this setting value will with printer, the difference of test environment and difference is arranged, only be example) with 10PF herein, can make that the induced voltage on the developer roll is smaller, then detecting unit will be lower than preset value with detected induced voltage, so printer will think that cartridge is unusual, thereby reports an error, stop to print; If detected induced voltage is higher than preset value, printer will think that cartridge is normal, then calibrates, and relevant information is write carbon powder box chip, ready after, just can start working.
In the normal print procedure of printer, detecting unit can continue detecting that the power of the ac signal that transmits between powder feeding roller and the developing roller is not stopped.When if the coupling capacitance between developer roll and the powder feeding roller has greatly changed unusually because of some, the ac signal that transmits between powder feeding roller and the developing roller also can have greatly changed, if the amplitude of variation of this ac signal surpasses default thresholding, printer will think that cartridge is unusual, and then the data in the modification carbon powder box chip, make the chip data saltus step, thereby finish the life-span of cartridge.Only detect this ac signal fluctuating range in allowed band, printer could operate as normal.
To sum up, printer in fact is provided with a thresholding respectively for the size and the fluctuating range thereof of the coupling capacitance between developer roll and the powder feeding roller, the value of having only this coupling capacitance is greater than thresholding and fluctuating range thereof during less than thresholding, printer is just thought the normal and operate as normal of cartridge, otherwise, thereby can think that this cartridge is unusual and quit work and cause cartridge not use.Yet in actual use, be included in that printer is installed new cartridge or when printer is normally printed, often also have enough carbon dusts in the cartridge, but because various abnormal causes can produce coupling capacitance less than thresholding or its fluctuating range situation greater than thresholding, make printer report an error, cause cartridge not use, this has just caused the waste of cartridge.
