A kind of Delevoping cartridge and comprise the handle box of this Delevoping cartridge
Technical field
The utility model relates to the Delevoping cartridge of image processing system use and comprises the handle box of this Delevoping cartridge.
Background technology
Image processing system is a kind of equipment that utilizes photoelectric technology.Photo-sensitive cell is its base components, and photo-sensitive cell has light sensitive characteristic, and under the illumination effect, photo-sensitive cell resistance descends, and electric conductivity increases.In image forming course, evenly fill electric charge with so that predetermined potential on the whole photosensitive member surface band at first for photosensitive member surface.According to the information of image to be formed photosensitive member surface is carried out optionally exposure then, the result forms electrostatic latent image at photosensitive member surface.Again then, utilize electro ultrafiltration etc. to develop, developer is attached on the electrostatic latent image, make electrostatic latent image visual.By transfer process, make the visual image of photosensitive member surface be transferred to image bearing medium again, with by photographic fixing, the result visualization image is secured in image bearing medium to last image bearing medium, obtains needed printed document through fixing member.
Developer is as a kind of important expendable part in image forming course, and common image processing system all has dismountable replacing formula Delevoping cartridge.Accommodate developer in the Delevoping cartridge.Normally, the box that only plays the replenishment developer effect is called as Delevoping cartridge.And developing cell is furthermore arranged, even the box of photo-sensitive cell is called as handle box.A free-revving engine of Delevoping cartridge provides developer, and the warehouse of a receiving photographic developer is at least all arranged usually, and the agitating element that works to prevent developer accumulation in the warehouse in the warehouse.
Along with the carrying out of print job, the consumption of developer, the residue developer of Delevoping cartridge will be not enough to effective imaging, therefore must change the Delevoping cartridge that developer is provided.So the method for residue developer level in the various detection Delevoping cartridges occurred.And wherein a kind of important method is called as light procuratorial organ formula (" beam transmission type ").
Application No. 10/878615, a kind of handle box is disclosed, the detection mode of residue developer level is a light procuratorial organ formula, this handle box comprises photo-sensitive cell, the developer-accommodating part, make electrostatic latent image obtain the developing cell that develops, be positioned at the light path part of propagation, the first developer transmission parts and the second developer transmission parts that are used to detect the residue developer level of developer-accommodating part.The first developer transmission parts transmits developer by himself rotating to transmitting developing cell, coaxial of the second developer transmission parts and the first developer transmission parts turning axle, and after the first developer transmission parts scraped the surface of light path part of propagation, second transmission parts transmitted developer to the surface of this road part of propagation.Since the setting of the one the second transmission parts, such Delevoping cartridge, and under light procuratorial organ formula, the testing result of residue developer level is more accurate.The disclosure handle box residue developer testing process is as follows:
With reference to Fig. 1, Fig. 2, when printing beginning (S1), the coherent signal slave controller 300 of printer prints is sent to the CPU 104 as information process unit, and light receiver is to detecting from light emission part 102 and the light beam L that passes handle box 2.Light receiver 103 sends signal to CPU104, and this signal was represented at predetermined length in the time, the amount (S2) of light receiving part 103 detected light beam L, and perhaps or rather, in the time, light beam L can pass the time span of handle box 2 at predetermined length.According to the relation of residue developer level in the time span that can pass handle box 2 and the handle box 2, it is handle box residue developer level (S3) that CPU 104 represents the conversion of signals of time span with this then.The residue developer level that draws when detection is not the required minimum of effective imaging, here with 0% expression, the normal print routine of then being scheduled to (S5).The residue developer level that draws when detection reaches 0%, will not print operation (S6), and must change handle box (S7) by display part 105 promptings.
With reference to Fig. 3,4,5, first transmission parts, 21, the second transmission parts 22 are arranged, handle box light entrance spare 23, handle box light exit spare 24, and the light exit surface 23a on the light entrance spare 23, the light incident surface 24a on the light exit spare 24 in the handle box 2.Light beam L from light emission part 102 enters handle box through light entrance spare 23, and under the unobstructed situation, light beam L is subjected to light entrance spare 23 in handle box 2, the guiding of light exit spare 24, and along Fig. 3, the dashed path of Fig. 4 is propagated, and arrives light receiving portion 103 at last.
As Fig. 3, the turning axle of 21, the second transmission parts 22 of first transmission parts shown in 4,5 is coaxial in turning axle 25.And in sense of rotation the phase place angle is arranged between first transmission parts 21 and second transmission parts 22, this angle is 60 to 120 degree.First transmission parts 21 plays clear light exit surface 23a and goes up developer D, and second transmission parts 22 plays a part to light exit surface 23a replenishment developer amount D again.When a large amount of developer D was arranged in the handle box, at the swing circle of each turning axle 25, with after the energy printing opacity, second transmission parts transmitted developer to light exit surface 23a to the developer on each light exit surface 23a immediately by first transmission parts cleaning.Thereby in each swing circle, it is very short that the detected light beam L of light receiver can pass the time span of handle box 2.When the developer level in the handle box is smaller, swing circle at each turning axle 25, developer on each light exit surface 23a is cleaned with after the energy printing opacity by first transmission parts, second transmission parts transmits developer to light exit surface 23a immediately and compares less, even do not have, the time span that the detected light beam L of light receiver this moment can pass handle box 2 is very long, along with the carrying out of printing, the further minimizing of developer, arrive certain predetermined value when this time span is long, promptly represent developer deficiency in the handle box 2, handle box is changed in prompting.Light transmission time and the curve of the corresponding relation that remains developer level with reference to Fig. 6 demonstration.
Light receiver 103 is generally phototransistor, and effect is light signal is converted to voltage signal, and when the light time that detects sufficient intensity, the output low-voltage signal is when detecting less than the sufficient intensity light time output high-voltage signal.Therefore in the light testing process, detected result exports with the form of voltage pulse signal, and as shown in Figure 7, high bit representation detects less than light, and low bit representation detects light, and the width t of pulse signal is then representing the time span that detects light.Thereby finally the width t by pulse signal is converted to and remains developer level in the handle box.
The main points of light procuratorial organ formula are light signal is converted to electric signal, and electric signal by the width t of pulse signal and the corresponding relation between the residue developer level, obtains to remain the testing result of developer level with the output of pulse signal form.Yet along with the development in the compatible market of printer, the handle box that a image processing system can supportingly have different manufacturers to produce, Delevoping cartridge.And compatible processing box or Delevoping cartridge can be designed to effectively to become printed document and required lower than the original-pack handle box or the Delevoping cartridge of former image processing system manufacturer production design to little necessary residue developer level, i.e. the higher handle box of efficiency, Delevoping cartridge.When this type of Delevoping cartridge cartridge during in former image processing system; regular meeting the prompting ahead of time of the high Delevoping cartridge of usefulness occurs and changes; yet handle box or still effectively imaging of Delevoping cartridge that this moment, in fact efficiency was high if this handle box or Delevoping cartridge are changed, cause the waste of developer.Therefore, the technical matters that the high Delevoping cartridge of usefulness can not obtain the prompting of Delevoping cartridge replacing accurately appears in regular meeting.
