For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with the drawings and specific embodiments the embodiment of the invention is described in further detail.
Embodiment one
The present embodiment provides a kind of Delevoping cartridge, please be simultaneously referring to Fig. 2～Fig. 4, described Delevoping cartridge 1 comprises powder storehouse 10 for receiving photographic developer, is used for stirring the puddle support 20 of developer, developer deliver to developer roll 50 powder feeding roller 30, regulate the powder outlet cutter 40 of developer roll 50 surface development agent layer thicknesses, developer is laid in the developer roll 50 on photosensitive drums (not shown) surface and detects the pick-up unit 60 of powder storehouse 10 amount of residual developer.
Pick-up unit 60 comprises light emission part 601, light receiver 602 and prism 603.
The first surface 6031 of prism 603 attaches and is fixed on the diapire 101 of 10 inside, powder storehouse; The incident end face 6020 of light receiver 602 is installed on the described diapire 101 towards 10 inside, powder storehouse, and the position of incident end face 6020 is corresponding with first surface 6031.
Adjacent and the second surface 6032 of the second surface 6032 of prism 603 and first surface 6031 is acute angle with first surface 6031.The first surface 6031 of prism 603 and second surface 6032 printing opacities, prism 603 is preferably prism; When prism was prism, the 3rd surface can be attached on the sidewall in powder storehouse 10, to guarantee not having light to see through from the 3rd surface.Also can be except first surface 6031 and second surface 6032, other surfaces of prism 603 be light tight, specifically can realize by the modes such as other surface coating light screening materials at prism 603.
The outgoing end face 6010 of light emission part 601 is installed on the roof 102 in powder storehouse 10 towards 10 inside, powder storehouse, and the position of outgoing end face 6010 is corresponding with second surface 6032.
The height of prism 603 can equate with the internal height in powder storehouse 10, also can be lower than the internal height in powder storehouse, and this is that the user can pay close attention to the surplus of developer usually because at the full box of developer or measure when more.Equal the situation of the internal height in powder storehouse 10 for the height of prism 603, pick-up unit 60 can detect the surplus that developer in the Delevoping cartridge is provided in real time.
The below equates to introduce the principle of work of the present embodiment Delevoping cartridge as example with the internal height in powder storehouse 10 take the height of prism 603 (for example prism).
Referring to Fig. 9, be the state of the full box of the developer in the Delevoping cartridge.First surface 6031 and the second surface 6032 of prism 603 are acute angle, because the full box of developer, therefore developer can cover second surface 6032 fully, the light that light emission part 601 sends can't arrive second surface 6032, therefore also not having light transmission prism 603 propagates into first surface 6031, and light receiver 602 does not receive light.
Referring to Figure 10, for the developer in the Delevoping cartridge used state after the part.Because developer makes the part of using up, because action of gravitation, the upper surface of developer can decrease, the AC section of second surface 6032 is come out, the light that light emission part 601 sends penetrates prism 603 from the AC section, and light beam appears from the DE section of first surface 6031, and the relevant position of light receiver 602 can receive light.
See also Figure 11, if corresponding area (being OEE ' O ') is as useful area in light receiver 602 with the OE section, then OD section corresponding shaded area (being ODD ' O ') in light receiver 602 is area corresponding to amount of residual developer.Because OD/OE=h/H, wherein h is the thickness of developer, and H is the height of prism, therefore, and h=H*OD/OE.
Optical receiver can be a kind of or its combination in photodiode, phototriode, photoresistance, the photosensitive circuit plate etc.When optical receiver adopts the photosensitive circuit plate, referring to Figure 12, the M of optical receiver, N position be the two-stage of corresponding photosensitive circuit plate respectively, be directly proportional with area, the light intensity of photosensitive region according to the electric current between the MN, and the relation that the thickness of the area of photosensitive region and developer is inversely proportional to, as long as the control light intensity is constant, the electric current I between the MN just is inversely proportional to h, can convert h to electric signal thus and detect.Figure 13 has shown electric current I between the MN and the relation between the h.Can calculate the surplus of developer by the electric current I between the detection MN.
When optical receiver adopts photodiode/phototriode, can one row's photodiode or phototriode be installed in the MN of optical receiver direction, thereby the principle according to the meeting generation current conducting after receiving light of photodiode/phototriode, judge which photodiode/phototriode conducting, judge thus the separatrix of light part and unglazed part, thereby calculate the surplus of developer.
Certainly, specific implementation also has a lot, and this paper does not enumerate one by one.
Be appreciated that after developer had used a part, the light-receiving area of second surface changed, and calculated thus the surplus of developer because the second surface 6032 of prism 603 provides an inclined-plane.Based on this principle, prism 603 can also be airtight hollow prism, its inner vacuum or be full of other light transmission mediums such as air.
Because at the full box of developer or measure the surplus that user when more can pay close attention to developer usually, therefore the height of prism 603 also can be lower than the height in powder storehouse 10, pick-up unit 60 can detect the surplus of developer in real time when the thickness of developer is suitable with prism height, and other states can think that the surplus of developer is sufficient.
The functional module that amount of residual developer is had an analytical calculation can be positioned at the Delevoping cartridge place the imaging developing apparatus or with the computer of described imaging developing apparatus interconnection on, the present invention does not do restriction to this.
The Delevoping cartridge of the present embodiment, by at Delevoping cartridge powder storehouse diapire a prism being set, utilization amount of residual developer not simultaneously, the area that comes out of a light transmitting surface of prism is different, and correspondence arranges respectively light emission part and light receiver at powder storehouse roof and diapire, calculate the surplus of developer, make the user can before developer is used up, know the surplus of developer in the Delevoping cartridge, and can carry out in advance the preparation that is replaced with picture developing apparatus or its Delevoping cartridge, be user-friendly to.When the height of prism equaled powder storehouse internal height, pick-up unit can detect the surplus that developer in the Delevoping cartridge is provided in real time.
In addition, because existing developer detection is except the light inlet window that utilizes light-emitting component, optical receiver and prism-type, also need in the powder storehouse, mirror surface be set diapire, the parts that form are more, production difficulty and cost are higher, and the pick-up unit in the present embodiment Delevoping cartridge is made of light emission part, light receiver and prism, and number of components is few, and production difficulty and cost all are reduced.
