As top about as described in the second and the 3rd embodiment, as long as a plurality of state detection unit stop and detecting in the process of identical developing apparatus state and detect the state of the same developing apparatus 11 that is positioned at developing location or the state of its toner Cartridge 13 at the single of the rotation of rotary unit 4, just can expect and utilize the detecting operation raising accuracy of detection of under the operation state of developing apparatus, carrying out.In addition, even in so-called monochromatic the printing, this image processing system also can produce suitable print image.For example, even when the monochrome image of carrying out the rotation do not relate to rotary unit 4 forms, also can detect the state of developing apparatus 11 of this monochrome component or the state of its toner Cartridge 13.
In first to the 3rd embodiment, various by reference structure examples and processing operational instances are illustrated preferred specific embodiment of the present invention.Yet, the invention is not restricted to the details of above-mentioned example.
For example, the timing (or constantly) about a plurality of state detection unit executing states detect has no particular limits for concrete timing, as long as described a plurality of state detection unit executing state detecting operation in the single of the rotation of rotary unit 4 stops is just passable.
For example, the situation of radio communication antenna 15 is the same, utilize at least one state detection unit under the situation of wireless communication, be desirable to, described a plurality of state detection unit in the single of the rotation of rotary unit 4 stops in different timing executing state detecting operations.The reason of doing like this is, by avoiding avoiding noise etc. at identical timing executing state detecting operation, otherwise the state detection unit of some executing state detecting operation can cause noise, thereby influences the result that other state detection unit executing state detects unfriendly.
First to the 3rd embodiment has illustrated that one of described a plurality of state detection unit utilize radio communication antenna 15 to read the situation of attribute information details.Yet, except reading information, perhaps, also can design and write attribute information as reading substituting of information.In this case, the attribute information of being managed based on the state-detection result or the image processing system main body of other state detection unit execution is specified information to be written.Specifically, except comprising a plurality of state detection unit, perhaps substituting as the part of state-detection, image processing system of the present invention can have the information writing unit, and this information writing unit writes the information relevant with the state of the state of developing apparatus 11 or its toner Cartridge 13 in the storer of developing apparatus 11.Executing state detected and information writes during state detection unit and information writing unit can be arranged as and can stop at the single of the rotation of rotary unit 4.
As mentioned above, it is described that the instantiation of the instantiation of a plurality of state detection unit or information writing unit is not limited to the foregoing description.State detection unit and information writing unit can be designed as by toner concentration optical sensor, toner concentration Magnetic Sensor, residue toner sensor, developing apparatus availability sensor, toner Cartridge availability sensor, utilize the appropriate combination of the DEU data exchange unit etc. of wireless communication to constitute.
The 4th embodiment
Above-mentioned first to the 3rd embodiment explanation be wherein to be arranged at each developing apparatus 11 in the rotary unit 4 exceeds the circumference of rotary unit 4 with uniform spacing situation.Yet the present invention also is applicable to the situation of developing apparatus with non-homogeneous pitch arrangement.
To illustrate now developing apparatus 11 with the situation of non-homogeneous pitch arrangement as the fourth embodiment of the present invention.Fig. 4 A to Fig. 4 C is the key diagram that illustrates according to the principle structure of the image processing system of fourth embodiment of the invention.
In general, the image processing system that is suitable for coloured image can form monochrome image, also can form coloured image.Therefore, the consumption of each color component of YMCK toning dosage is not always consistent.For the big color component of its consumption of toner, the volume that increases toner Cartridge in the developing apparatus can effectively reduce the frequency of replenishing toner.
Therefore, shown in Fig. 4 A, in the described here image processing system, the volume of toner Cartridge 13 of developing apparatus 11 that is used to distribute to the bigger color component of consumption of toner (specifically, the toner of K color component) is greater than the volume of the toner Cartridge 13 of the developing apparatus 11 of distributing to other color component.Therefore, when developing apparatus 11 was installed on rotary unit 4, the arrangement pitch of each developing apparatus 11 was uneven.
Even in having the image processing system of this structure, for example, toner concentration detecting sensor 14 and radio communication antenna 15 also can be used as a plurality of state detection unit.Specifically, be positioned under the state of developing location at the developing apparatus 11 of distributing to the K color component, radio communication antenna 15 be positioned at developing location and distribute to the memory transactions data of the developing apparatus 11 of K color component.And toner concentration detecting sensor 14 detects the toner concentration (referring to Fig. 4 A) of the developing apparatus 11 of distributing to the Y color component.Therefore, toner concentration detecting sensor 14 and radio communication antenna 15 executing state detecting operation in the single of the rotation of rotary unit 4 stops.
Yet, when the arrangement pitch of each developing apparatus 11 is inhomogeneous; For example, when the developing apparatus 11 of distributing to the C color component is positioned at developing location, be positioned at towards the detection position of toner concentration detecting sensor 14 and there be not (referring to Fig. 4 B) in the developing apparatus 11 of distributing to the K color component.Therefore, toner concentration detecting sensor 14 does not have to detect the toner concentration about the developing apparatus 11 of distributing to the K color component.Because the K color component is than the formation influence littler (even when K color component unavailable also can form coloured image) of other color component for coloured image, therefore even when not detecting the state of K color component, also can reduce to minimum for the adverse effect of the picture quality that keeps forming qualitative picture.Yet, in order to keep the high image quality of K color component, other sensor can be set also, be used to detect the toner concentration of the developing apparatus 11 of distributing to the K color component.
For example shown in Fig. 4 C, even in such image processing system, promptly, the developing apparatus 11 of distributing to the K color component is not arranged in the rotary unit 4, be provided with but be independent of rotary unit 4, and the developing apparatus 11 of distributing to other color component YMC is arranged on the rotary unit 4 with proportional spacing, detects the state of Y color component, M color component and C color component during toner concentration detecting sensor 14 and radio communication antenna 15 also can stop at the single of the rotation of rotary unit 4.
As mentioned above, can in the scope of marrow of the present invention, carry out various modifications to embodiments of the invention.
